Losing control

It was around 10 o'clock Friday night. Mom and sis and myself was wacthing tv. Mom stood up and said I'm off to bed I have to work tomorrow and starts to down the hallway. When sis jumps up and yells mommy wait, and takes off behind her. She said I"m tired I'm going to bed soon I love you and hugs her I yell dont forget Josh is coming over after work amd spending the night. He is going to help me in the yard like dad asked before he left. I love you. Laying on the couch it was about 5 minutes later sis came out. Not paying attention to sis I was watching the movie. She came over and laid on top me. I say get off me Im watching this.I feel her rubbing her little breast agianst my arm. I can feel her pussy through her panties she going up and down on my leg. I knew thats what she had on thats all she would wear around the house. I keep tring to push her off of me but she wont stop all of sudden we slid down to the floor we rolled around some. I rolled her over to her back she grabbed my arm and rolling over ending up on top of me. She straddling me smashinh her firm tits against me. She slids up my chest now her tits are pressing against my face. She slid back down I feel a strange pressure against my cock. She looks at me smiling she said that feels good dont it. I like it as she keeps rubbing on me. Every once in awhile I feel her press down and holds it. I buck up kneeing her in her tight ass lifting her up hooking her legs with my arms pulling her over my head. Thats when I seen she didn't have any panties on so when she went over her pussy rubbed from my chin to my forehead. She rolled to the side to her ass with her knees up. In shock I roll over to my side facing her. Before I could say anything she spread her legs and puts her hand between her legs. She says I can't believe you done that. I blurt out let me see your pussy. She says ok she raises her hand. Now I can see it up close. I say open it up I want to see everything turning red I say I havent see one for real. My sister puts a hand on either side seperating pussy open with her thumbs. She shows me her tiny little hole. I say can I get closer. Moving up I see the light pink inside the hole looks to be about the size of a dime. Asking may I touch the outside Moving her hands I reach out I start by running my finger between her inner thigh and the mound of her pussy. I can feel her thin pubic hair as I run my finger around the top then down the other side. I run my finger up the slit then back down. I start to go back around and the door bell rings I say shit as I jump up with a major hard on. We both jump on the couch and sis covers up I pull it over my hard on I yell come in comeand sits down. Josh saus what have you been doing wrestling and laughs. WE start watching the movie explaining things to Josh at it goes on. Josh asked got something to drink? I said yeah go get what ever you want. I feel my sister slip her foot betwen my legs rubbing my balls through the leg of my shorts. She grabs my foot and and moves it up her leg. I can feel my foot run over her knee starting up her thigh. I feel my toes on her inner thigh thats when she she holds it there. I try to move my toes but she holds them. Josh walks back in so sis pulls her foot back so I try to but she wont release it. After the movie was over Sis got up and said Im going to bed. When she gets up her ass was out showing her pussy to ma. By the time josh turned to see whats going on sis has pulled her shirt down and went to bed.
