I calmed down but the words cock and fuck were bouncing around in my head. The woman began to moan loudly again, forcing herself on to his cock with h...r cunt (another rude word bouncing around in my head). The man was breathing hard now, muttering that he was close. I watched enthralled as his movements sped up until I could hear the noises his cock was making in the woman’s wet cunt. I realised that my own sex (cunt) was wet, too. Again, I had to shove my hand in my mouth as the man pulled his. She pulled my mouth to one and let me suck on her nipple for a while and then she pulled my head to the other one and let me suck on that one for a while too. I could feel each nipple harden in my mouth and I could tell that Marilyn was enjoying it too even though she tried very hard not to let her brother know that.When Marilyn thought that I had had enough she got on his bed, centered herself on it, and then opened her legs up to allow me access to her pussy. Pete kept telling me what to do. When he saw my body quivering violently, he stepped back and pulled out a large knife and he continued pinching a nipple.My eyes opened wide and a high pitched “noooooooooo,” escaped my mouth. I could not move from the electricity moving through my nipples down to my cunt. My legs were jelly and my heels pointed out from my body and my legs automatically spread open. My hands were trying to crab his wrist but could only shake.He placed the knife between my breast and in one VERY, VERY easy. I sucked her lips and boobs . I played with her boobs while was telling the answer. I liked her nice ass and I spanked her when ever Anup gives wrong answer. He was not ok with me spanking her naked mom but he had no option so he studed well and completed the syllabus in 20 days. He had 10 days to practice. Divya was so happy by his son’s improvement. Me : Bitch today is 21st day get ready to give me a nice blow jobAnup : Please don’t make my mom suck your cock I can’t watch thatMe : ok I won’t.
