I pulled her shorts down as she tried to hold them up. "Take them off, I know you don't have underwear on." "Dad! what?" "I watched you change Sara I ...as in your closet when you came home." "What, dad I'm a little young for you, and I am your daughter." I grabbed her shorts and pulled them down, her pussy looked so nice. "You know you want an older guy you can have sex with." I grabbed her arms and her hands touched my dick. "Dad uh dad I'm not...no.....let go." I turned her around and grabbed. Blimey! I undid my jeans and pulled them down, along with my y-fronts. I moved back and took in the scene of Anne staring into my eyes while her pussy was wet and open waiting for me. “I'm on the pill, its OK,” she said.I plunged right into her, losing my virginity, my engorged knob encased in her tight hot and wet hole. I put my hands around her and pulled her bottom towards me as I gave it to her. I thrust in and out while my brother stood rapt at the sight of his girlfriend being rogered. My nipples are very sensitive. Now the dress. I slipped my arms in and lifted it over my head letting it fall down over my body. It barely covered my groin and the little black panties weren’t doing a good job of containing my cock. It was standing out to one side hard. God, I was scared but felt so fucking sexy. I decided to walk downstairs and see what happened.As I entered the living room David was pouring wine into two glasses. He looked up. “Oh baby you look good dressed like that…” He. I danced with several of the men and because of my 'tipsy' condition most of them thought they could get away with grabbing a feel or pushing their hard cocks into my leg or belly, but I pretended to ignore it which only made them bolder. Even when I got caught under the Mistletoe and the kisses got a little heated, I didn't care. After all, I would be going home to Danny and he would be getting all the benefit of the sexual heat that the guys were generating in me. And they were causing me to.
