It's fun, I like most of the guys there, some are jerks, but that's to be expected, my classes are okay for the most part. I do well. My Dad supports me in my education. He gets involved when I need him to be. Otherwise he's not all over me and into everything I do. I love him. He rocks. The assignment in Mr. Hardwood's Male Physiology class is a research project where we're supposed to stimulate the penis for extended periods of time and then measure the amount of sperm ejaculated at the end of that session. Mr. Hardwood our teacher has been leading class discussions and demonstrations on the various techniques, body parts, responses, observations, and other stuff we'll need to know to gather data for the project. Coach Long was a guest in the class and we learned how to read non-verbal signs of a pending orgasm. We then had to practice at home with our Dad or other Male family member. When my Male Physiology class begins, we're to write the previous nights edging figures on the class chart. I did so again today recording an edging session lasting 32 minutes for my Dad. I noticed that almost all the other figures were larger too. It seems that with practice our techniques are getting better and we're able to know better when an orgasm is going to happen, and stop it. For this class, Coach Long was again invited back into the class room and Mr. Hardwood demonstrated testicular stimulation, along with all the other techniques we'd learned so far. It was a fantastic demonstration. Coach Long was totally naked this time and Mr. Hardwood wanted us to take note of abdominal contractions and flexing as the glans and testacies were stimulated at the same time. Because we had only one piece of data for the chart when we entered class (Our Dad's length of time being edged) the demonstration session lasted most of the class time because there was nothing to discuss. The figures spoke for themselves. What was fascinating about this demonstration was that Mr. Hardwood was able to keep Coach Long on the edge of orgasm for a full 50 minutes. Every seven minutes Coach Long would be close to a powerful orgasm showing all the signs; tight pulled up scrotum, hard heavy breathing, sweating, head thrown back, eyes closed, flexing his abs and legs, and then Mr. Hardwood would bring him back down. He would allow Coach Long to rest for one minute and then start the ministrations to Coach Long's cock again. Bringing Coach Long to the edge yet again while not inducing an orgasm. I'd never seen so much pre-cum issue from a cock before as it did from Coach Long's that day. We all took careful notes about how Mr. Hardwood touched Coach Long's balls with his finger tips and how he swirled his other fingers around the head of Coach Long's cock. We learned that a cock ring is very useful for this as it holds the penis hard and erect while keeping the balls tight and away from the body. At the end of the class demonstration Coach Long was sweating profusely and breathing hard, as if he'd been pumping Iron for an hour. His veins were prominent, his muscles hard from flexing, and his hair matted from the sweat. His cock still dripped pre cum. Mr. Hardwood said, "Class let's thank Coach Long again for his help with this demonstration." We all thanked the Coach and watched him as he dressed and left the class room. Once Coach Long had left Mr. Hardwood made this observation. "It's clear that within the next few days of edging Coach Long will not be able to handle an edging session that lasts one hour. Although he's been able to handle the build up, most men are not able to last 10 minutes after edging for several days in a row as will be the case with Coach Long. Particularly if the edging sessions consist of several minutes of focused penile stimulation followed by a minute or two of rest. This causes a build up of sensations and anticipations that drive men over the edge. I predict that Coach Long will have an orgasm within 10 minutes of the final edging session when all techniques are used together. He will assist us in demonstrating and I also predict he will ejaculate well over 20 milliliters of sperm." "The last edging technique we will demonstrate with Coach Long will be nipple stimulation. The male nipples when touched and stimulated produce great waves of pleasure that directly effect the sensations felt on the glans. Couple that with testicular stimulation and most men have an orgasm with in 10 minutes." Minutes before the class bell rang Mr. Hardwood said, "Tonight is the third night of your homework assignment with your Dad or male family member. Since you practiced last night with out inducing an orgasm, I suspect some Dad's will not be able to hold back an orgasm tonight, and because you're still learning to read non verbal signs you'll probably induce an orgasm without seeing the signs; it's bound to happen. Don't worry. Do your best. Take your readings and measurements and tomorrow document them on the chart." Testicular stimulation with Dad "Hey Dad tonight we have a new technique to practice. You interested in helping me?" I asked my Dad as we sat around the dinner table. "Sure son I'd be happy to. What is it?" "We're adding testicular stimulation to the practice sessions. I'm supposed to stimulate your glans and frenulum and then also practice stimulating your balls." I answered. "Last night was good, you had me on the edge a few times. Can I have an orgasm tonight?" Dad inquired. "Well it's not an issue if you do, but I'd like to practice all techniques and make all the observations I can of the non-verbal signs. It's important that I know these. The best way to learn is constant practice." "If you have an orgasm too soon, I might not take you through all the pleasure sectors our text book addressed. I'm supposed to look for signs that your orgasm is near; like your breathing coming faster, you might sweat more, you will produce lots of pre-cum, your cock will be really hard, and your balls will pull up." I added, trying to sound knowledgeable. "Okay." Dad said. "As you know I'm happy to assist you. You still want me to remain silent while you practice?" "Yes please remain as silent as you can. It does a few things. It allows me to concentrate and practice my technique and it will help you focus too. You'll want to try and steady your breathing. Talking might break our concentration." I again tried to sound like I knew what I was talking about, I didn't but I was ready and willing to learn. As we sat at the table and ate dinner, I thought it might be interesting to just practice now, while Dad was eating. He'd be focusing on his meal and I could get my homework done at the same time. That would leave time for other stuff later. "Um Dad may I be excused just for a minute? I'd like to get some things." "Sure son." Dad answered. I got up from the table and headed to my room to collect my things for the class research project. Cock ring, timer, measuring vial, and Jack off cream. When I got back to the table Dad was still eating, but this time he was also reading the evening newspaper. I felt a bit hesitant but I had no reason not to trust Dad. "Dad, I'd like to start the practice session right now, here at the dinner table. You won't have to do a thing, you can continue to eat and read. I'll wash up the dishes and clean the kitchen if you say yes. Practicing now will save me some time for gaming later. Is it okay?" "So you want to practice your edging techniques on me right now, here, at the table?" Dad asked as he looked over the top of the newspaper at me. "Yeah, is it okay Dad?" I asked. "Well as long as I can finish my meal and read the paper, sure practice all you can." With Dad's agreement I took my things, lifted up the table cloth and slipped under. The table cloth fell back down behind me and I looked straight at the pant legs of my Dad. I moved up to his legs and reached up and began the awkward process of unbuckling his belt, unbuttoning the top of his pants and unzipping his fly. By the time I'd gotten all that done his cock was beginning to grow in anticipation and strained against his pant legs. "Dad stand up a bit would you please." I asked. When my Dad stood, I swiftly lowered his pants down to his ankles. Now exposed to view were two nicely haired muscular legs and a noticeably hard cock tenting his boxers. I started the timer and then moved my hand inside Dad's boxers and pulled his cock and balls out the front opening. I slide the cock ring down over his now engorged cock and over his balls. I was ready to do my homework. I started with the basics, swirling my fingers around Dad's cock head, stimulating the frenulum and feeling each pulse and swelling. Dad instinctively moved his knees further apart, but his pants sort of acted to restrain his feet from moving. What I also noticed was Dad's cock became super hard. I think it had to do with his upright sitting position. Something in his having to sit upright on a chair caused his cock and balls to stiffen more. I also noticed Dad had moved to the edge of the chair. All this was interesting and I made note of it in my mind. As Dad spread his legs with each swirl of my fingers I felt a pulse in his cock and witnessed the first flow of pre-cum. Again knowing what to do I spread the clear slick fluid all over Dad's cock. I heard him stifle a moan; his legs tensed for a minute and shook. As I worked on Dad's cock under the dining table, Dad must have been busy eating and reading above. I did not hear anything from him, but I did hear soft moans and whimpers as I gently touched his balls with my finger tips while at the same time stimulating his glans with my other fingers. Since I was to practice testicular stimulation this time I now focused my attention on Dad's tight ball sack. The cock ring forced his balls out so I had easy access to them. They were nice sized, and the scrotum was smooth. It dawned on me then that maybe Dad shaved his balls. Hmm I thought that's interesting. I wonder if shaving one's balls heightens the sensations when they are stimulated. What I did now to Dad's cock I know would meet with Mr. Hardwood's approval. After all, copious amounts of pre-cum were flowing from Dad's cock head so it only made sense I stroke his raging hard on with one hand while gently touching and stimulating his balls with the other. I did this for several minutes. I first started with his right testicle as it hung down lower than his left. I gently scraped it with my finger nail. I then moved over to his smaller left testicle and did the same thing to it. Dad's knees were spreading, shaking, and moving with each touch I made to his balls. Again I think I heard soft moans of pleasure from Dad, but it was hard to tell. I continued to stimulate his glans, but this time I used the ball of my hand to surround his entire cock head as it allowed me to stabilize his cock at the same time as I stimulated his balls. I noticed his scrotum was pulling his balls up with greater frequency. Constant stimulate of Dad's frenulum was causing intense pulsing of his cock and pre cum was flowing freely. I moved my left fingers to his cock head and this time swirled my fingers faster, back and forth around the head of his cock. The large amount of pre-cum made this easy to do. I then gently scarped my finger nails on Dad's ball sack. First stimulating one ball and then the other. Because I was right there, up close to his cock and balls, I could in fact see some change in his cock. It did appear to grow tighter or bigger. I thought I saw his cock head swell but because I was under the dining table the lighting was, needless to say, not the best. I was doing my homework basically by touch and feel. What happened next was amazing. With out any notice, without me conclusively feeling any hard pulsing from Dad's cock or seeing any immediate swelling in his cock head, Dad's legs stiffened, he moaned out loud and said, "Ugh son I'm coming, I can't hold back any longer. I can't take it!" and rope after rope of white cum hit me in the face! Dad shot, bucked his hips, shot again, bucked his hips and shot yet again! Six times in total, each load being warm, white, salty, and slick. A powerful long lasting orgasm. I did my best to stop the timer, collect Dad's sperm in the vial and see at the same time! "Dad what happened?" I wailed as I sat down on my butt and looked at Dad's still pulsing cock. "You were supposed to hold back from having an orgasm." "Son your technique is fantastic. When you started to stimulate my balls while at the same time stimulating my cock head I couldn't hold back any longer. It was too much for me son. I tried I really tried to hold back." He panted. At this point I crawled out from under the dinner table and was greeted by Dad's handsome smiling face. Mine still had some cum on it, but I used the measuring vial to collect it. With Dad's powerful and unexpected orgasm over I looked at the timer it read 45 minutes! "Wow Dad, you lasted 45 minutes. I edged you for 45 minutes and the time flew by. I thought I was under the table for just a few minutes before you came." I said with surprise in my voice. "Amazing Dad. I had no idea. This seems to confirm Mr. Hardwood's thesis, the longer the edging session, coupled with the intensity of the stimulation, produces a larger load of sperm. I can hardly wait to report my findings. But I wonder if this will be accurate information as I was not able to collect your sperm as it dripped off my face. Maybe I should not report this data as being accurate." I said with consternation in my voice. "Whew son I don't know about the figures but with each new technique you learn and practice the better it is for me and the harder it is to hold back my orgasm. There were times I thought I was gunna blow. I'm sure Mr. Hardwood will be okay if you provide an explanation for the data being inaccurate." Dad was looking at me and smiling, I could tell he loved me. He said, "I'll finish my dinner son, and then you can clean up as you promised." "Okay Dad." I said with a smile. My Dad is the best.
