I am a single step dad. My step daughter is 20. She had asked if her friend and her could sleep at my place after a party they were going to. I never turn her down when she wants to come over. I went to bed while they were out, but I woke to bumping and giggling. They were obviously drunk when they came home. I didn't think anything of it and dozed back off. I heard them come into my room. They were giggling but whispering. Then they were on my bed. I stayed 'asleep'. THen one of them pulled the covers back, and then I had 2 sets of hands rubbing my crotch. I instantly got hard. They giggled and joked and played with me. Eventualy I was out of my boxers and they were rubbing and kissing my cock. I could feel I was close to cumming, but I didn't want to stop the fun. I just let my orgasm go. They giggled and kissed my cumming cock. Then they left. That was 1 month ago and nothing has been said about it and nobody is acting any different. I know its wrong but I want it to happen again.
