My fiancé's friend is a registered sex offender. After serving his time in jail for a few months my fiancé offered to let him stay with us. Now I've only met him a few times before when I was pregnant and he's always been quiet around me so I just had to trust my fiancé's judge of character, especially since they've known each other since they were children and are like brothers . Apparently this friend was 23 when he was flirting with a 17 year old at the time he was convicted (he's 27 now). My fiancé and I have a 4 year old girl so obviously I expressed my concerns and he assured me nothing would happen. Sure enough he's kept to himself and would only make small talk to me in the morning before going to the guest bedroom the rest of the day. On Christmas Eve we decided to play some family games together and were sitting on the couch playing on his switch. My daughter occasionally would stick her butt out and shake it whenever she won or was winning the game we were playing. I just told her to knock it off. A few moments later she spread her legs wide open exposing her pink panties and the sides of her bare pussy lips. She started scratching and rubbing and expressed that she was itchy. This time my fiancé told her to stop it or we would stop playing games together. She did twice more only less widespread as to not be so obvious. Each time I checked my fiancé's friend's face for a reaction but his face was turned towards the screen. I did catch him quickly trying to look from the corner of his eyes. It made me feel so hot. Eventually I got up and took her to the bedroom where I told her I would put on medicine to make the itchiness go away. She loves spreading her legs and did so after I took off her panties. I took my time rubbing Vaseline over her tiny pussy. She even spread her lips for me so I got a close view of her cute little clit and extremely tiny hole. After a bath I let her suck on my nipples for the little milk I still have left. I was so wet from the day that I just started fingering myself as she suckled. Once she fell asleep I ran my wet fingers over her bare mound carefully. She didn't budge. So I ran my index finger between her smooth pussy lips. I want to watch my fiancés friend drench her pussy in cum. I want him to let her suck his cock and watch her tiny hands grip him. I never thought I would be turned on by something so wrong. I want him and some perverted friends to rape us both and use us as fucktoys whenever my fiancé is at work.
