When I was about 14-years-old, my 19-year-old sister asked me to play a game where one of us would lay down and close their eyes while the other could touch wherever they wanted. The person being touched could not open their eyes. I had never even seen a naked girl so I was really excited about this! It was my turn to lay down first. I was wearing old slightly ripped pajamas with no underwear. I closed my eyes and my sister began by touching my chest and legs. I had a raging hard on, and she unclasped the little metal button holding my erection in. When my cock popped out, she must have just looked at it for a couple of minutes because she stopped touching me. She then touched the head of my penis and touched my balls with her fingers. She tried to close the clasp, but it was worn out and she just sort of pulled my unbuttoned pj pants to cover my hard on. She said ok time to get up, and I sat up with my erection protruding from my pjs sticking straight up.
It was then her turn. I touched her body a little, and then pulled her sweater up. She had big tits, and I touched them and played with her nipples. I unbuttoned her pants, and touched her through her underwear. She was moist and I put my hand inside to try to touch her pussy. I rubbed it and tried to find her opening to put my fingers in but I think she didn't want me to go that far so it was game over.
