I was still getting over my daughter Tina was 5 months pregnant by some boy at school. She was only 16 for fuck sake, too young. Her mom excepted it. Anyway my wife was heading away for a few days with her book club, a few days holiday leaving Tina and me to try to get on after falling out over pregnancy. It was the first night and we decided to try and get on, so had a movie night. As we watched the movie Tina started to cuddle up to me and I noticed her nighty had rise high also how big her tits had become. The thing was I getting aroused by her. I know it was wrong and my problem was not only was she my daughter, but pregnant women turned me on. As we cuddled up I strokes her shoulder letting my hands stroke her and slowly down making sure I touching the side of her breast. She just smiled that’s nice dad. I became more bold and started caressing breast. Suddenly she began stroking my cock through my trousers. Oh dad I’m making you hard. My face turned red with guilt. But when she undone my zip and took my cock out. She stoked it up and down then she lay done and began sucking it. My hand slipped up her nighty and began playing with her pussy, which was wet. For such a young girl she could suck cock. It was my turn I got her naked and began sucking and licking her sweet tits, and those beautiful brown nipples. Mmmmm yes dad she shouted use me. I caressed her body before burying my head between her legs and licking her sweet pussy. Pushing my tongue and fingers inside her to made cum. I felt her juices cover my face. I then slid my big hard throbbing cock inside her. And began fucking her with hard strokes and soon I found a rhythm to we I fulled her with my sperm. Omg I just fucked my teenage daughter. After we finished we lay in silence for about ten minutes. She got up and went out off the room. I sat thinking what I done when the door opened Tina was standing naked, she looked to me and said dad come to bed please. I got up followed in to my room. She got into bed opened her legs and said fuck me again. I was soon inside her I wanted to kiss her taste her, smell her own her. For the next couple days and nights I took every chance to make love to her. When my wife came home she asked me what had changed, we looked very close. When I left you were disgusted with her. I replied I come to my senses. When my daughter has her baby she had a boy. But unfortunately she fell out with her partner. We all worked together but when we could I ended up fucking her. Can’t complain about sex because I was now fucking both my wife and daughter. Tina has shocked me by suggesting that we should have a threesome, but I’m not that brave yet or can I, we see.
