This story was done by request. It is the third story in the series. One was in the gay incest section and one was in the bisexual incest section. They are basically the same but different. This one merges the two into one story so if you like this one you might like the other two. The name of the gay version was "Role Playing Step-Son" and the other one was called "Role Playing Step-Daughter". Role Playing Step-Children by: Playtime69 "Hey, kids. Time to get up." I told my two step-children as I entered their room. The children were my wife's children from a previous marriage. They were twins, one boy and one girl 15 years old. The kids really loved me and enjoyed the special time we could spend together, especially when their mother was not involved. Being twins they were pretty much the same size and had similar looks. I guess the biggest difference was one had a penis and the other had a pussy. Kimberly was my step-daughter and Christopher was my step-son. They were small for their age but very healthy and full of love and happiness. Kimberly, or Kimmy as I called her most of the time had long light brown hair and green eyes. Kimmy had a cute set of 34A breasts and a figure that had just began to take shape. She was a little short and quite thin for her age, and was very cute. Christopher, or Chris as I called him most of the time, and Chrissie when his mother was not around was cute with medium long light brown hair and green eyes. Chrissie had a cute cut 5" completely shaved cock with smooth bare balls. He had a figure that many girls would have liked to have had. It would not have been hard for him to have been a girl and I guess that was why Chris played like he was a sissy girl baby when we played our little games. He was a little short and also quite thin for his age, and was cute on the girlish side. "Come on you two. Your mother has gone to work and today is Sunday. I thought we could make this a special play day. So get up and let's eat breakfast." I said with more firmness. This being a play day did the trick. They loved when we had a special play day. It was different each month but most of the time was exciting. Chris was out of bed first before I made it out of the room. "Chrissie! Looks like you are ready for play day already." I said as I looked at his 5" hard male member. "Daddy!" He yelped. I just smiled. Just as I went to the kitchen I heard Kimmy giggle when she noticed his hard dick as it left the room. I checked on Amber as I passed her door. She was still asleep so I thought I would let her sleep a while longer. Amber was Jill and my biological daughter. She was only nine months old and as cute as a bug. Amber was a good baby that did not cry or fuss much which was nice being I normally had to get up early to take care of her when my wife was at work. I worked late shift so I would not get to bed until three or four each morning. My wife, Jill, worked early shift so she would get up and go to work early in the morning. This would leave me to see to the children each day until my wife would get home. I fixed breakfast as my two 15 year old children got cleaned up and made it to the kitchen. They both were still naked just like I was. None of us liked wearing many clothes so when Jill was at work we allowed ourselves to have some extra freedom. "Daddy, what are we going to do today?" Kimmy asked. "I thought we would go to the park. I will fix a picnic lunch and thought we would take the diaper bags and would spend the day having some fun." I answered as I placed their plates in front of them. "Goodie." Kimmy chirped. Chris also piped in with, "Fun." "I even got us something special for today." I mentioned with a silly grin. "What?" They both asked at the same time. Smiling I replied, "You will see. Just finish your breakfast first." We all finished eating as we talked about what we would do at the park. When finished we all worked together to clean up the dishes. I told the kids to go wake Amber up, feed her, and to get her diaper changed and dressed while I got stuff together for the day. I laid some stuff on their beds and got the diaper bags and the picnic lunch ready. I went to the kitchen where I found them just finishing up feeding Amber. I put Amber in her play pen while the kids and I got ready to go. "Oh, Daddy! They are so cute." The kids said as they saw the matching diapers on their bed. "I thought it would be fun if we all wore matching diapers today. I found these online and was able to get all the sizes we needed. I got plenty so we can match all day long." I said with a smile. Kimmy was just about to slip on her diaper when I said, "Hold on there little girl. You know the rules. You and Chrissie need to go shave your privates while I do mine. Then I will be back to watch you pee before dressing." They scampered off to the bathroom to shave. They loved shaving together because they would help each other to make sure all the hair was gone. I went to my own bathroom and also shaved my privates. When finished I headed to their bathroom to watch them pee. I found that they would hold their pee until they were diapered so they could fill it up faster. I liked it to be a while before having to change them. "Hurry Daddy! I got to go." Kimmy called out as I got close to their bathroom door. I entered the bathroom and Kimmy quickly sat on the toilet and spread her legs just in time for the pee stream to start flowing. She really had to go bad as it seemed not to want to stop. Chris then took his turn. He sat down and spread his legs and soon his little dick was pouring its pee right into the toilet bowl. I was next. I sat down and spread my legs so the kids could see my pee as it escaped my freshly shaved dick head. We then used some baby wipes to get cleaned up and then we all dresses in our diapers. Kimmy put on a cute little short skirt and short tee shirt. Chris put on a pair of shorts and a tee shirt. I then dressed in a pair of shorts and a tee shirt. I then changed Amber into her little matching diaper. We grabbed all our stuff and out the door we went. Soon we were at the park. I found a spot far away from anyone else and completely hidden. We had done this before so there was little to be said out loud. We simply began to strip. We all removed all our clothes except our diapers. It was so cute seeing all three of the kids wearing the same pretty print diaper. Then when you added my matching diaper clad private area to the group it was enough to make anyone shoot a load of cum. We threw a ball around a while making sure we drank lots of liquid. We had been there an hour or so when we stopped to take a break. "Anyone need a diaper change?" I asked. Chrissie said, "I do not know. Maybe." "Guess I will need to check." I said as I reached out and felt his diaper covered privates. It was not full but felt like he had made a deposit. I then reached over and felt Kimmy's diaper. It was a little fuller but still did not need a change. I checked Amber and her diaper was filled and needed to be changed. I laid out the diaper changing mat and the twins gathered around to watch. I pulled Amber's diaper off leaving her completely naked out in the open. I used the wipes and cleaned her little baby slit up and slipped on a clean diaper. "What about your diaper, Daddy?" Kimmy asked. "Well check and see." I told her. She reached out and grabbed my hard cock through the diaper. She quickly said, "Daddy. You are hard. Your diaper is wet too but is not too full yet." I giggled and said, "Yeah. I know." I handed them all a drink and I too drank a big bottle of water. Amber had her bottle so we all sat there on the blanket drinking lots of liquid. It was not long when I began to fill my diaper up. I had drank so much I knew my diaper would not hold it all. "Chrissie, my diaper if full but I still need to pee. Can I put some in your diaper?" I begged. He jumped up and pulled on the waist band of his diaper. He pulled it out from his body as I stood up and positioned myself in front of him. I pulled my semi erect dick from my own diaper and let it hover just above his opened diaper. I let the flow of pee begin. It was a strong stream than hit his hairless now growing little dick. The stream splattered on his privates and ran down across his shaved balls and was soaked up by his diaper. It was not long after I began peeing on my step-son that he began to add his pee to mine. His diaper began to fill up quickly so I cut off my stream and asked Kimmy if she had room for some of Daddy's pee. Smiling she said she did and she too stood up and pulled her diaper away from her body. I positioned my dick above her opened diaper and began to pee on my step-daughter's little hairless pussy slit. Watching my pee hit her tight pussy not only relived the pressure in my body but was causing me to get hard. By the time I was emptied I was hard. I stuffed my 7.5" erect cock back into my wet diaper as I suggested we all get changed before eating lunch. "You first Daddy." Kimmy suggested. I laid out the changing pad again and laid down. Kimmy tore off one side of my diaper while Chrissie tore off the other side. They pulled the wet diaper forward and my hard cock popped out. The smell of fresh pee and a hard cock was more than Chrissie could take and soon he was sucking my dick with all his might. He played with my balls as I laid in a soaking wet pee filled diaper. The next thing I know I felt his finger being inserted into my asshole. He began giving me a massage internally as he sucked and pumped his mouth up and down on my dick. Kimmy not wanting to be left out began to give me a French kiss that was the best ever. Our tongues were playing touch and tickle as her small fingers began to play with my nipples. My mouth being busy and in the position that I did not want to change I began to pump my dick in and out of my step-son's mouth to let him know I was about to blow. He caught on quickly and began to suck more as he shoved his fingers as far up my ass as he could. I exploded with a super big load a hot thick cum. He sucked and drank my load like a pro. When my balls were drained and my breathing back to normal he pulled his fingers from my hole and allowed my now limp dick to plop from his lips. Kimmy wanted to also taste my cum so he moved from French kissing me to French kissing her twin brother. I watched as they kissed. Their lips locked together and their tongues played in each other's mouth. Their bodies pressed together and their diapers rubbed tightly against each other. I laid there watching until they pulled from each other. I knew they did not stop because they were finished. I knew they would not be finished until they had both cum but first things first. They pulled the soaking wet diaper from under my butt , cleaned me up, and put a new diaper on my private area. I told Kimmy to lay down and had Chris tear off the sides of his sister's diaper. He pulled the wet diaper down allowing the world to see her perfectly shaved hairless pussy slit. Chrissie began to lick her slit to clean it up. I watched as I could tell his dick was about to pop out of his diaper. I reached out and ripped the sides off his diaper letting it fall to the blanket. I pulled it away and watched as his super hard 5" dick bounced up and down. "Fuck her. Fuck your sister. I know you want to and I am sure she wants you too." I told Chrissie. He lifted up and looked at me. He then looked at his sister and before he could say anything she pulled him on top of her naked body. I picked Amber up and sat her in my lap pointed at her half brother and sister. Amber and I sat quietly and watched. Chris lowered his body down on top of his sister until his dick made contact with her pussy slit. Kimmy reached between them and guided her brother's dick into her super wet pussy. Kimmy moaned as her brother began to slip his manhood into the baby pussy underneath his body. His cock found its way deep into a hole it had been in many times before. "Oh, Sis. I love the feel of your little young baby pussy hole." Chris moaned. "I love you, Chrissie. Your little hard shaft inside my tight baby hole feels so good and right. Fuck your sister and fill me up with your special milk." Kimberly begged. Chris had no control left. His hard cock was buried balls deep into his 15 year old twin sister. Her butt still laying on a wet diaper that was filled with her pee. My 9 month old daughter was still sitting in my lap watching her half brother and sister fuck each other. All this pushed me over the edge and I began to rub my own hard cock through my diaper. "Fuck me Chrissie! Fuck my baby pussy!" Kimmy begged. "Oh Baby! Your bald baby pussy is so hot. I cannot hold back any longer." Chris moaned as he pounded in and out of his sister's tight cunt. Two minutes later he blasted a load of cum so hard and big that Kimmy squealed as she too came at the same time. Their cum mixed together as I continued to watch the show. When his balls had been emptied and their orgasms had subsided, he pulled his semi-erect prick from her bald pussy slit. Their cum flowed from her hole like a river and splashed onto her already wet diaper. They kissed one more time before I sat Amber off to the side and cleaned her up putting her into a clean fresh diaper. I then cleaned up Chris and re-diapered his lovely hairless private area. We took a break from sex and ate lunch. We then all laid around in our diapers before getting up to take a walk. We walked around hoping no one would see us in diapers. We ran across a couple of kids that looked close at our diapers but said nothing. It was kind of exciting having other children see me in a diaper and wishing that they too wanted to play diaper games but not knowing who they were that thought quickly faded. We played ball some more before doing another diaper change. "Chrissie, would you like to make a deposit inside your daddy's hole?" I asked Chris. "I sure would." He quickly replied. "Lay down and I will get you ready." I heard Kimmy tell her brother. He laid down and she ripped the sides off his diaper. I watched as her lips wrapped around his growing shaft. She took him right up to the point of no return before pulling back. With his hard shaft waving in the air, he stood up and Kimmy told me to lay down. She ripped the sides off my diaper and she then sucked me until I too was hard. She had me to get up and she then laid down where I had been and proceeded to take her diaper off. "Stick that big cock into my pussy, Daddy." Kimmy begged. I bent over and easily pushed my big hard cock into her well cum lubricated snatch. I pumped a few times then told Chrissie to shove his dick into my asshole. He quickly did as I requested. I laid on Kimmy with most of the pressure on my arms as not to crush my little daughter. Chris began to pump his cock in and out of my hole. Each time he went into my ass he pressed me into Kimmy's pussy hole. So as he fucked me I fuck his sister. With some warning from Chris I was able to time my ejaculation to match. Chris shot his load of cum into my asshole causing me to shoot my load into Kimmy's tender baby pussy. My load splashing inside her pussy caused her to also cum. I looked over to check on Amber and saw her with her hands on her diaper. I was not sure if she was imitating what the rest of the family was doing or if it was because she needed a diaper change. I checked and she did need a diaper change which I did. I then cleaned and diapered Chrissie. Kimmy was next with a cleaning and new diaper. I was last and allowed both the kids to clean and diaper me. We then dressed and left to go home. By the time we got home we needed one more change which we quickly did. We all showered and got dressed in real clothes before Jill got home. When Jill got home she would always find Amber squeaky clean and in a fresh diaper and clean clothes. Kimberly and Christopher would be dressed in shorts and tee shirts. I too would be dressed in shorts and a shirt. Dinner would be almost ready and soon we would be eating a nice dinner and chatting about our day, well parts of it anyway. The End
