Last night I was taking a bath and dozed off. As,I was sleeping in tub I got a h****** for some reason. It had felt like there was a hot moth on my Johnny. I wake up to find my cousin giving me head. I wad grossed out by it but it felt good. I've came allot but something about her made me Fill the back of her throat up plus her mouth. I was so into it I had her stripped and had us having s** In bathtub. I ended up c****** inside her and she wasn't on birth control.all while I did this my fiancee is in other room. How should I tell my fiancee that I possibly could've got my cousin pregnant?
