Rene and I were very close. I had been playing dress up with her for years. I got into  Little League baseball, and I hadn't dressed for month's. One day a few weeks after  school started Rene  needed  "sister time " Dad was away for 2 more days, so it was cool. I didn't have practice or a game, so I said of course. I looked through my choices and found a peasant dress and a low pair of heels. Just a little blush and lipstick and I was set. I wore the shoulders down. Rene was waiting for me on her bed. She had a Polaroid camera and took 2 pics of me. She made sure I blew a kiss in the  second one. I played it up for her. Then she said sit down with me.  She told me she had a secret that could never get out. Her best friend  Mexican girl named Martha was dating a high school boy. OK so what is the big deal? She said Martha was a woman now. I must have looked confused about that. She had gone all the way with him. Oh my  that was big news.  The high school boy had a friend who wanted to  go out with Rene. She said that they were big jocks and really popular with the girls at the  high school. She said they were on the JV football  team. I didn't know that meant Junior Varsity. Not the big deal team. But she needed to tell me everything.  

Martha met him roller skating on a Saturday night. He got her number and  called a couple times a day. They went to a movie and a couple of other places.  No big deal. They started  making out followed by a bit of  touching her toys.  that led to her first hand job. He had to tell her how that was done. They  progressed to  blow jobs and  finger banging her anytime she let him. They were ready to go further and she gave it up in the  back seat of  his Nova. All of this happened in about 7 weeks.  My cock was hard and I had trouble hiding it. The  silk panties felt great and  the mental pictures were hot!  Rene  had met his best friend at the skating rink last week and he had been calling her. Tim and Ron, real high school football stars.  Ron wanted to take out Rene. She said she was really interested in him. Mom's voice called out to  get things ready for dinner. I  couldn't quite stand up because my hardon was going to be  noticed by Rene and Mom to. Rene noticed that I was trying to cover up my cock. She giggled and said just wash your hands before I  help set the table. 

At dinner Mom said I was as pretty as always. She asked why. I didn't want to snitch just because I  told her. She smiled and said good enough for me!  After dinner Rene dropped a Bomb. I couldn't tell anyone about Martha or my pictures would be found at school! I panicked and I begged her to give them back. She said no of course. I was really hurt by that. She  knew I was not going to tell  anyone about Martha and Tim. She said that it was because she was the only one who knew. Yeah fucking Right! So Ron came over to meet Mom and Dad. Mom said as long as it was the 4 of them there was nothing to worry about. Dad reluctantly agreed. I would be filled in on Rene's progress in  about a month. They had been making out and Ron wanted her to give him a hand job on their next date. Rene had touched it through his jeans but hadn't actually seen his  cock yet.  She asked me for a big favor. She said Martha  almost freaked out when he  first showed her his cock. She said she didn't want to seem like a that when it was her first time to see it. My cock was hard again and I almost freaked out when she asked me to show her mine! Mom had run to the store so now her chance , before she would see Ron's cock. Your my sister! I know I was being,stupid but Rene said she would give the pictures back, so I agreed. I stood up lifted the pesant dress  and told her Ok. She pulled my pantied down and slowly reached out to touch little brothers cock.NoI didn't almost cum it was weird ,and nice.She asked if my cock(thingy)was huge. I told average,Iguess. She told me what Martha said Tim had said. His 5 inches was pretty big. I had 5 and 3 quarters. And I was still in JR high school  . I felt kinda proud about that!She stroked my cock and  made a couple comments. I liked her steady hand and her eyes following her hand on my cock.We heard the door close and my cock was quickly back in the panties. She and I talked about it after dinner. We agreed weird but nice. I quickly offered any more help she  might need. She smiled knowing that meant anything. I hoped I could but I wasn't really was't ready at alL.
