I went over to my sisters house and she said her hubby (my step-brother in law) was extremely horny and hadn't cum in a few days. I wasn't sure why she was telling me this until I found out he was saving his load for me. I licked and sucked his cock up and down, with my step-sister helping me every now and then. I could feel it getting harder and harder, with the head of his cock growing until I felt him explode in my mouth. Mmmmm ... that warm think cum!! I just LOVE it. This was SOOO taboo ***This is the MP4 version, presented in 640x480p.***
