Punishing My Brother by: Playtime69 I was 17 years old when my parents left me in charge of my younger brother. They decided to take a long weekend trip out of town and left me to watch after Andy my 12 year old brother. My name is Brian and I just graduated high school and was planning to attend college in the Fall. I had big plans which included going to medical school once I had my undergraduate degree. I had good grades in school and had taken some college classes during my senior year in high school. I had a job which required some of my time each day, so when my dad asked me to watch over Andy I agreed with the understanding that he would be on his own until I got home from work around 3:00 each day. They had warned Andy to be good telling him his best friend James could hang out with him but not to get into trouble. With plans made our parents left town and I headed off to work early Saturday Morning. The job I had was not too demanding but was not going to help me get ready for college either. I walked into the house shortly after 3:00. Things looked to be ok at least there was no obvious damage, but then I did not see my brother either. I called out with no response. Starting to worry, I headed upstairs to his room to see if they were up there playing a video game. Opening the door I looked in and was stunned by what I saw. Both Andy and James were sitting on the floor in front of the TV. There was a video game on the screen but they were not playing. They were just sitting there. Both of the boys looked to be asleep, or were they? "Andy." I called out. There was no response so I tried again. "Andy, you ok?" Still nothing so I entered the room and thumped him on the ear to get his attention. Andy looked up at me with a glazed look in his eyes. He smiled at me, giggled, and said, "Oh, hi Brian. Whhhaaaatttt'ssss uuuuuuppppppp?" Looking in his eyes and listening to his slurred speech I determined he was drunk. I looked at James and he too had the same look on his face but he could not talk. I found a couple glasses and took a sniff of the contents and determined they had been drinking bourbon. I took the glasses down stairs and found where they had gotten into our father's liquor cabinet. "Great. This is all I need. Two drunk kids. And I will get blamed." I thought to myself. I began to work out a plan that would keep me out of trouble. The first thing was to make sure they were ok. Then they will need to sleep it off. Finally, James' folks will never need to know. I headed back upstairs and determining they had not drank enough to get sick or harmed I proceeded to the second part. They would just have to sleep it off. I figured that by 8:00 they should be able to eat something which would help. I helped my brother into bed removing his shirt and pants so he would be more comfortable and would rest better. Next I helped James to the bed. I took his shirt and pants off also and helped him to lay down next to my brother. I turned off the lights and closed the door. I did some work in my room while the two kids slept it off. Mom called and I told her everything was ok and for them to have fun. I told her we were going to have pizza tonight for dinner and for her not to worry. I checked on the two a few times and finally just before 8:00 I found them to be coming to. I got them out of bed and told them to get dressed. I explained they needed to eat so we were having pizza. About then the phone rang. It was James' mother wondering where James was and why he was not home. I told her that they must have lost track of time and that we were just about to have pizza. I asked if it would be alright if he ate first before going home. She said it was alright if he was not causing any problems. I said everything was fine and would send him home in an hour or so. Deciding I was going to have to do all I could to make sure James' parents did not get suspicious, I went back to my brother's room. They were still sitting on the bed in a daze. They had got dressed but that was as far as they got. "That phone call was James' mother wanting to know why he was not home yet." I announced. "With a scared look on his face James asked, "What did you tell her?" "I told her that you two had lost track of time and that we were about to have pizza and asked if you could stay and eat. She said that was fine." I told them. "Thanks." James said. "You are not off the hook yet. Unless you want to get caught you will need to do what I say." I told them both. "Ok." They replied. "First you two will need to take a shower while I order the pizza. To save time you will need to shower together." I began saying. "Together?" Andy complained. "Yes. There is nothing wrong with two guys showering together. So get to it. NOW! Unless you want me to call James' mother back and explain what you two did today before I got home." I threatened. "NO! WAIT! We are going." James yelled out and in 10 seconds flat he was naked and on his way to the shower his 3" limp dick flopping around as he headed off. Andy quickly stripped and with his 2" dick he too headed off to shower. I yelled at Andy to put on clean clothes when he was finished and I grabbed up James' clothes to throw them in the dryer to air out. I did not have time to wash and dry them so I figured if I just fluffed them up with a couple dryer sheets they would not smell so strong of alcohol. I tossed the clothes in the dryer and ordered the pizza. The pizza was delivered before they were finished so I set the table and when Andy was dressed he came downstairs. I yelled up to James and told him to come on down that I had his clothes in the dryer taking the smell out. He walked down naked and looked more sober now. He dressed and we all ate. I explained that I had covered for them and that James had better not tell anyone, but also that they would have to promise never to do that again. Once James left I took Andy to his room to talk to him as I had more plans for his punishment. "You know Mom and Dad left me in charge and I cannot let you completely off the hook. You know what Dad would do to you so I figure I had better punish you like he would have done if he were here." I began telling Andy. "No! Please! I promise I will never do that again." Andy begged. "Would you rather me tell Mom and Dad?" I asked. "No! Not that. Anything but that." He pleaded. Looking him in the eye, I said, "I think this calls for seven smacks to the ass. Do you think that is fair?" He looked down and continued to plead for me not to spank him but he liked the alternative even less. I then gave him the choice to get spanked or for me to tell Dad and let him take care of it. He finally agreed that seven licks would be the best all the way around. I told him to get ready and I went to get the paddle. I returned to find him bent over the edge of the bed. "Oh, no! You know the rules. All spankings require a naked ass. So, off with the clothes." I demanded. He pulled his pants off and bent over again. I told him to get his underwear off or else. He then quickly removed his underwear and stood in front of me naked. His cute little 2" limp dick was totally bald. His balls tucked between his legs still tight against his body. He was cute and the longer I looked at his male parts the more interested I got. He finally turned around and bent over expecting me to begin spanking him. His butt was as cute as his dick was. It was a sweet tight looking butt that was screaming for some attention. Just as I was about to take the first swing something came to me. I could use my brother in my medical training. I had wanted to get some real person to learn male body parts from and now was my chance. "Andy. Were you serious that you would do anything to keep from being spanked?" I asked. Andy raised up and looked at me saying, "Yeah, I guess." "Well, you know how I plan on going to medical school so I can be a doctor, right?" I started building to the final end result. "Yeah." He simply replied. "I have been wanting to do some examining of the male body. So if you let me 'play' doctor with you then we will forget about this spanking thing that you should be getting. How does that sound?" Finally getting to the decision time for Andy. Andy looked at me wondering if I was serious or not. He then asked if it would hurt. I told him that part might be uncomfortable but should not hurt too much. I explained I wanted him to do a mock visit to a doctor for a physical. Which would mean several questions and some tests along with the exam. He stood in front of me still naked thinking. Eventually he said he would be willing instead of being spanked. I told my brother to get dressed and come to my room. While he dressed I got things ready. Andy walked up to my room and was a little confused to see me sitting in a chair outside my door. I told him I was the receptionist and would ask some questions before he was going to see the doctor. He said he understood. "Do you have an appointment to see the doctor? " I asked Andy. "Yes, I do. My name is Andy and I am supposed to have a physical today." My brother now was getting into the mock examination. I figured he was making sure I would not spank him later if he did not do what I wanted. "Nice to meet you, Andy. Have a seat and I will let you know when I have a room for you." I said still being the receptionist. I then went into the room and got the rest of the things ready. A couple minutes later I opened the door and called my brother into the room. I told him I was now the nurse that was going to do some basic stuff before he got to see the doctor. He understood and sat down in the chair I had ready for him. I asked him some basic questions that I already knew the answer to but was trying to make this as realistic as I could. I got his name, age, address, phone number, reason for seeing the doctor, and a few family history questions. I then took his blood pressure and pulse. Taking notes on everything for future reference was just another step I took to continue with this plan. When I had all the information I felt I needed, I told him to strip naked and sit on the bed and wait for the doctor. He giggled at having to be naked but never complained. I walked out leaving my brother alone in my room to strip. I told him the doctor will be in to see him soon. I then walked out and gave him time to strip and get on the bed. A few minutes later I walked back in to see Andy naked and sitting on my bed. "Hi, Andy. My name is Dr. Brian. How are you feeling today?" I began with. "I am feeling much better than I was earlier today." He stated. I chuckled then said, "I bet you do." I looked over the notes from the nurse and commented, "I see your pulse and blood pressure are a little high. This could be from you being nervous. We will check again later to see if I am right." I began the exam by looking in his ears, eyes, and throat. I commented that his eyes looked pretty red but compared to earlier they were not too bad but his throat was a little red which might be from drinking strong alcohol and being so young. I listened to his heart and lungs and said everything sounded good. I did all the basic stuff you would find with a basic exam. I wrote everything down for later use. "Ok. It all looks good so far. Now I would like to do two more tests. I would like to check your testicles for lumps and then I want to do a prostrate exam." I told my brother. "Ok." Andy agreed. "You will need to stand up and I will check your balls for lumps that could mean a problem." I told him. He stood up and I gently took hold of his still limp dick with one hand and began to check his balls with the other. I tried not to squeeze too hard but I wanted to do the test correctly too. When I was finished I told him the next test was not going to be so pleasant. I got some lube and told him to bend over that I was going to have to insert a finger into his ass to check his prostrate. This made him very uncomfortable but when I reminded him of the alternative he promptly turned around and bent over. I put some lube on my finger and placed it at the entrance to his butt hole. I then began to push until I got it inside. I began to probe inside his body to check what I needed to check. I found everything to be normal. I pulled my finger out and cleaned his butt crack with a tissue. I then cleaned my hands while he stood up and faced me. When he turned around I noticed he was hard as a rock. His tiny 2" limp dick was now a much longer steel rod. "Looks like you ended up liking that test." I mentioned. Giggling he said it did kind of feel good once my finger was inside him. Not knowing why but my dick began to rise at the thought of my actions causing him to get an erection. Up till now all I had said, thought, and done had been professionally accomplished. But, now with the exam over with and his hard cock in front of me my thoughts had began to change. "Thanks for letting me do the examination. How would you like to be a part of a sex study I have been wanting to do?" We had never been a sexual family. It was not like we never saw each other in underwear or naked before but we just never did or said anything sexual. So, when I brought this up it took him by surprise. I could tell he was thinking about it by the way he looked at my growing package under my shorts. It had probably been a long time since he has seen me naked and I know he had never see me hard so he was probably wondering how big I was. After a few minutes he finally asked, "Will I get to see you naked?" "Sure at some point if you would like. Here look." I said as I pulled out some papers I had been keeping records on. I then explained, "I began keeping records of the size of my dick and different cumming information since I was 11 years old. I had always wanted to keep records on other boys but never got the nerve to ask anyone, until now." "Mom and Dad will never know, right." He checked. "Oh, No. Never." I stated. "Ok then. I will do it." He agreed. I told him the first thing was to get some personal information and some measurements. I told him first I needed a measurement of him limp so for him to go watch TV until he was limp and without thinking about sex he was to run back to me so I could get a quick limp measurement. I told him that this measurement would probably be the hardest to get. He laughed and agreed as he told me he was usually pretty horny and was hard most of the time. I laughed and told him I was the same way. He ran off to the living room and turned on the TV and waited for his dick to go back down. Being 12 years old I knew it was not going to be an easy task so I just sat and waited. Eventually I heard him running up the stairs so I got my ruler ready and as soon as he walked into the room I shoved the ruler next to his cock and held it out to get a good measurement. His limp dick measured 2.25" which was not too bad for a 12 year old boy. "Next I will need a measurement of you hard. That should not be too hard to get but to help I will ask you some questions for my data charts." I told him. He agreed and I began to get the information I wanted. He said he began touching himself when he was 11 but did not know how to jack off till about three months ago. He had been shooting cum for about a month. He had not tasted cum yet. When I began to ask questions about him doing things with other boys he got real quiet but his dick began to spring to life very quickly. I finally got out of him that he had jacked off with James several times and they both enjoyed it. They had never fucked or sucked each other either. They had touched each other but had not jacked each other off. Then Andy told me something that surprised me. He said that he was not opposed to experimenting with another guy. This information was very helpful because now I figured I could have some fun playing with his cock and he would probably play with mine. I finished with the questions and found his cock was almost as big as I had seen it earlier. I asked him what I could do to make him as hard as possible. To my surprise he answered my question in one word. He simply said, "Strip." I figured he had done a lot for me this was the least I could do for him right now. I removed my shirt dropped my shorts and then removed my underwear. My hairy semi erect cock plopped out into clear view. That was all it took and he bounced up to full mast in seconds. I grabbed the ruler and found him to be a good 3.75" long and a decent thickness. "Now we need some cum shooting measurements and times." I began saying. I had found out he had not cum in a few days so I told him this first time would not mean too much but would need be to done for a base. I said we would need to measure how long it would take, how much cum was shot, and how far it shot. Then in 24 hours we would do the same thing again and would have to do it every 24 hours for a week. This was really making him happy because he had enjoyed cumming and knew now it would even be more fun. I suggested that he should talk to James to see if he wanted to be a part of the study. It was getting late but not too late to call so he called James and they talked a while. James said he would love to be a part of the study and that he could come over tomorrow after dinner. I really hated to do this but I told Andy we would just postpone the first cum until tomorrow and would do both at once. He did not want to wait but said he would. We decided we would go to bed so we would not be tempted to jack off too soon. The next day I had to work but got home as soon as I could. I made sure neither of the boys had jacked off and we soon had dinner. James came over just as planned and I went through the same exam and set of questions I had gone through with my little brother. James was 13 years old and was just getting hair around his cock. He measured 2.75" soft and 4.25" hard. He did not have any lumps on his balls and his prostate seemed to be fine. I did notice he liked me sticking my finger up his ass and that it went in a lot easier than they did with my brother. I did not ask anything at this point but I did make a mental note about it. "Like I explained earlier, the next step is for me to get some information and numbers from cumming. What I will do is jack each of you off one at a time. The one not being jacked off can sit and watch but they are not allowed to touch their dick. I will get three different bits of information. One will be the length of time it takes to cum from start to finish. The second number will be a measurement of how far you shoot your cum. Finally, the third will be how much cum you shoot. Is this ok with you two?" I explained and checked. They both said it sounded like fun and looking at both their erect cocks sticking straight out I felt like they were ready. I set up the things I needed to get the measurements and had Andy sit in the 'examine' area first. I started the timer and began to jack him off. Stroked fairly fast at first then after a minute or so I picked up speed. James was watching what I was doing and Andy was looking at James' cock at the same time. It only took a few minutes before Andy expelled his load. I wrote down the time it took, how far he shot, and how much he came. I then set up for the second participant. I told Andy and James to switch places and began to jack James off. It took him longer to cum but shot further and with slightly more cum. I could not tell which one enjoyed the test more as they both had really big orgasms. "Thanks guys. I really appreciate this. Now I would like to know if you would agree to a month long study. Let me explain. Starting tomorrow for seven days we will do this same thing that we did today. I will jack each of you off and write down the information. Then the next seven days we will go through a different method giving me a second set of data. The third will be another way and then the fourth seven days will still be something different. I will explain the method on the first day of the seven day period. Waiting to tell you the method helps not to damage the data. Does this sound alright with you two?" I questioned. With a big smile James asked, "So we will each get to cum 28 days in a row?" "That is correct." I answered. "I'm in." Andy quickly agreed. "Me too." James added. "There is just one thing I will have to ask of you both." I told them. "What is that?" They both asked at the same time. Chuckling I said, "I will need you both agree not to play with each other or your own cock. And, no cumming at all unless I do it to you or are in the same room so I can get the information for my study." They smiled at each other then again they said together, "Ok. We promise." I told them that it was important to do this about the same time each day. We discussed the possibilities and since there was no school till the Fall we would do it after diner each night. We would take turns doing it at James' house and our house depending on who was home. James had a little 9 year old brother that he wanted involved in the study but since he was not cumming yet it would not do any good. I told him we might do something after the 28 day study was finished but not to tell him anything until this study was over. He agreed but said it would be hard to keep him in the dark for long especially if we did the research at his house. Things were going well and we had no issues. I was getting some really good information for my study and the weekend was coming up. We had almost got through one week and the only thing I found an issue was my own excitement. I had no idea I would be getting so horny from jacking off two young boys so I was really glad it was Friday. I had a date with my 16 year old girlfriend, Amy. Amy was a hot little number that I had been going out with for a couple years. We had been fucking for about 6 months and had been making plans for the future. Her parents really liked me and I liked them too. It was an overall good situation, that is as long as they did not find out I was depositing cum in their daughter's pussy every chance I got. After diner the boys met in my room for their daily 'milking' and once we were finished I took a shower, got dressed, and headed to Amy's place to pick her up. We were going to a movie where I was hoping she would play with me during the show. I arrived only to find out that her parents had just left for a diner engagement and that Amy was all alone. We had a few extra minutes to spare so I asked her if I could come inside, giving her our special, "I want to fuck you," smile. She let me in and we instantly began to kiss. Barely making it to the living room before my pants and underwear was off. I reached under her short skirt and pulled her panties down as I laid her back on the couch. I parted her legs and slipped my super hard cock into her tight pussy in a matter of seconds. "What the fuck?" Amy moaned. Not know what she was talking about I continued to fuck her tender pussy. I pounded her hard and fast and just before I pumped my cum deep inside her she exploded with a massive orgasm herself. I finished delivering my load just as her orgasm was subsiding. "Wow. That was my biggest orgasm yet!" Amy said. She then asked that probing question, "Why are you so horny and how did you get your cock to be so big?" Trying to down play the reason I asked, "What are you talking about? We have not fucked for almost a week and it is the same cock that I have always had." "Oh, No! There was something different this time. You were a wild man and your cock was twice the normal size. Soooooo?" She continued digging. I continued to put off the real reason all while getting dressed and getting into the car. I thought I had her taken care of until she brought up the possibility of another girl. That was the last thing I wanted her to think. I loved Amy and would do nothing to hurt her. I figured it would be best if I just told her the truth. It was just a study any way and had nothing to do with me having sex with the boys, not really. I then told Amy about the study I was doing and what all it entailed. By the time we got to the movie theater I was hard again just from thinking about the study. We got out and she looked down seeing my big bulge she said, "Ok. I see you really do like this study you are doing. I guess it is ok with me. I will enjoy it too." I was not sure what she was talking about and I certainly was not going to ask now that I got her calmed down. We went into the movie and sat down. There was no one right next to us so she proceeded to play with my cock and I slipped my hand under her skirt. We were getting close to another orgasm when a couple sat down just behind us in a position they could see so we stopped before getting caught. When the movie was over I took her home and walked her to the door. Her parents were home so I figured I had better take her inside and talk to them for a few minutes. We chatted for a while before I told them that I had to work the next day and that I needed to get home. Amy walked me to the door giving me a good night kiss. I was so horny again that I almost jacked off on the way home. As soon as I got home I went to my room and stripped. I got into bed and began to jack off. My door opened and looking up I saw Andy standing there. I quickly told him I was busy. With a smile Andy said, "I see. Can I watch?" "You know the rules. You cannot play with yourself. Can you watch without getting so horny you have to play with your cock?" I asked. "Of course." Andy replied. "Ok, then. You can watch if you pull your pajama bottoms down so I can see you dick." I stated. Without a word he walked over to my bed and dropped his bottoms. His cock now growing quickly was tempting. I stared at his now hard hairless boy dick as I pumped my cock. I blew my load in record time. I was not sure if it was all the talk Amy and I had, the playtime we had in the movie theater, or looking at Andy's prick sticking straight out at me that did the trick. I just know it was an excellent orgasm with lots of cum. I told Andy thanks for letting me look at him but reminded him not to touch his cock. He gave me a brotherly kiss on the lips and headed off to bed. That night I slept as sound as a rock. We finished up the week with the study and the start of the second seven day period was met with excitement. Soon as the boys showed up for their daily cum shoot, they wanted to know what was going to be different. "Are you ready to some extra fun this week?" I asked. They both were already naked and their dick hard and ready to squirt. This told me the answer to the question without them even saying a word. I asked them if they knew what butt fucking was. They did know but they said they had never done it before. I looked at James and asked him if he had ever had anything up his ass. Eventually, he said he had shoved a hairbrush in his butt hole to see what it felt like and that he liked it so much that he does it from time to time. "Well this week you two will be butt fucking my ass." The reason you will be using me is that way you both can be using the same hole and I can get some good information." I began to explain. This must not have sacred them because their cocks just got bigger and harder, if that were even possible. I explained, "You each will have to wear a condom so that I can measure how much you cum each day. During this week I will be keeping track of how much time it takes from the time you enter my ass until you shoot your load and how much you shoot. From the time you enter me until you cum you will need to fuck me as fast and hard as you can. I do not want you to stop and start or try to prolong the event, ok?" With pre-cum oozing from their dick heads they agreed. I told them that Andy would go first today then James would go first tomorrow. Each day they would alternate. I slipped a condom on Andy's stiff dick first followed by James' cock. I lubed up my asshole and put some on their rods and with the timer ready I had Andy enter me. Andy did not have a very big dick so there was no pain at all. I did feel him inside me but was not something that was all that noticeable. He came pretty quick then removed his rod so James could have his turn. James' rod was longer and thicker and I could definitely notice him being inside me. There was no bad pain but there was a little discomfort at the beginning. By the time he came it was feeling rather pleasant. He too came pretty quick. When I measured the amounts I found they both shot more cum than when I jacked them off. I found this interesting. The next six days was a lot of fun. I enjoyed getting my ass plugged by two young boys each day. I did want to know what it would feel like to have cum squirted inside of me and was hoping once this study was over that one or both would help me out with this question. The third seven day period was set aside for oral sex. Again to keep things level I had to do the job myself. This was by far my least favorite method as they still had to wear condoms because there was no way I could get a good measurement of their cum each day. They each were suited up with a condom and one at a time would lay down in front of me. I would them suck them off with my mouth. I would also slide up and down as I sucked. It was probably because of wearing a condom but I found they took a long time to cum and would not cum near as much as the other methods. Now with the three main ways of coming tried and the data recorded I wanted to do more of an interest or preference study. Along with the types of information recorded for each method I added one more bit of information for this next seven day period. For the last seven day period I let them choose which of the three methods they wanted for their daily cum. I did add the possible choice of them using each other's asshole as an option. I was not surprised that the first day Andy wanted to try James' butt out. I think he had wanted to do this for some time and when given the choice he jumped at it. James also wanted to put his cock into Andy's asshole. This was a tight fit and was a little painful for Andy but he managed. This produced a very quick time for James and his cumming. The amounts of cum pretty much were the same though. They did enjoy being able to choose the way of cumming. I did find they like fucking much better than the other methods with oral being last on their list. This very well could have been because they had to wear a condom. With all the data collected and all four of the seven day periods finished I wanted one last cum recorded the exact way the first time was done. This way I could see how day one compared to what would happen after 28 consecutive days of cumming. I set it all up and took the readings and found that after 28 days of cumming it took them longer to shoot and they produced less amount but then on the other hand they still enjoyed it just as much. I wanted to do something special for them for all the hard work they had done for me so I asked Amy for a suggestion of what I could do for them. I had kept Amy informed on what all was going on with the study and she was also getting a lot out of it because I was always super horny and fucked her to really big orgasms. I was a little surprised when she gave me her suggestion. "I do not know if you will like my suggestion but it will be one more bit of information you can add to the study." She began telling me. She then dropped the big idea on me. "Let them fuck my pussy." My cock shot up instantly when she suggested that. It was not because I wanted my girlfriend fucked by someone else but the thought of watching another cock slide in and out of her hole was very exciting to me. Knowing that it was someone that was just doing it for sex made it alright in my mind. I would make them wear a condom so I could record the amount of cum but I did think they would enjoy it. I asked the two boys if they would give me just one more day. I did not tell them why and I do not think they cared knowing they were going to cum again with my help. They showed up at the right time. I told them to strip, which they did quickly. I slipped a condom on each of the cocks then I stripped myself. They still did not know what was going to happen. With their stiff cock coved in a rubber and them ready to explode one more time there was a quiet knock on the door. I thought they were going to jump out of their skins. I told them it was ok and I went to the door and opened it. Amy walked in and said, "Hi boys. Want to fuck my pussy?" If their cocks had went down any from fright at the knock on the door they went right back up when she asked the question. They both said they did so Amy began to take her clothes off. I thought the two of them were going to explode before they even entered her pussy. With Amy totally naked she laid down on my bed. I let them flip a coin to decide who fucked her first. The winner was my brother. Andy jumped on the bed shoved his cock into her hot wet hole and began to fuck her like he was possessed. He shot his load faster than he had cum in any of the past sessions. The amount of cum he shot was also a record amount. Next up was James. He was not so fast as Andy in getting to her pussy but was not hesitant either. He fucked her longer and harder but still came more than he had cum with any other method. Now with my girlfriend laying on my bed still naked after being fucked by two young boys, I figured she needed some pleasure so I decided to show the boys how to make a girl happy. I climbed on top and began to fuck her with long steady hard strokes. She was beginning to moan as her pussy was tightening up around my dick. I knew she was just about to cum so I stepped up my speed and hardness and in no time she was spraying cum on my cock. I made my deposit inside her and got off. My cum began to ooze from her pussy as I climbed off the bed. I looked over and saw both boys hard as a rock once again. The thought hit me about letting them fuck her again and allow them to make their own deposit inside her. I whispered in her ear my idea and I could see in her eyes she was very much willing. James was first and as soon as his naked stiff penis entered her hot slippery hole he exploded. He had not even taken a minute before he added his cum to the mix. He admitted that it was the best thing he had ever felt. Andy took a little longer. Probably because he was not quite as old and needed more down time in between fuckings. He too came pretty quick and by now the cum was really flowing from her hole. Watching her get fucked again turned me on even more and now I too had to go one more round. Jumping into bed with her, I quickly shoved my now hard dick back into her sexy cum covered hole. I worked on her about five minutes before she came again followed quickly by one more blast of my own cum. Her pussy was overflowing with cum and with the bed now soaked we all got cleaned up and dressed. We each gave each other a nice long kiss. I explained that this was the end of the study and they were never to shove their cock in my girl's pussy again. They understood but also now had other means to an orgasm. Not long after this last day, Andy told me that him and James now butt fucked each other every chance they got and he wanted me to know how much they both appreciated me teaching them about sex, even if it was just a study. The End
