I took her right leg up with my right hand and tried to thrust inside her, it was damn painful and she screamed and bite my shoulder on my left. She b...te me so hard, I’m not sure now that probably she was virgin or in periods, I don’t know still, but she was sobbing wasn’t moving and even I had immense pain since I felt all my penis was so deep inside and my skin over the penis was so pulled back due to sudden thrust inside her. We both were just still like that. Shower was on one side and. “Then kiss me” she said, adding another beautiful smile. I leaned over and she and I locked lips. I opened my mouth and she actually sucked out all of the contents. As she did, HE sat next to her, watching intently and fondling her breasts. She smiled and tuned her head toward him…. And to my surprise, he leaned over and kissed her and she passed him his own cum that was inside her cunt, my mouth, her mouth and now his! Once the contents were inside of his mouth, she turned to me.“Any left down. .." I interrupted, "Carrie! Sleeping with your sister is not something I imagined I'd have to do to win her favorable report. Is this really something you want me to do or is this some pressure that you don't understand from your sister?" I want this to happen." Carrie kissed me passionately. She explained, "I love my little sister. Until we grew apart because of being apart for university and other responsibilities, we were so close. I look at this as bringing us back together again with you. Gina leaned down and whispered in my ear. "I was surprised when she asked if she could suck on you, too." She kissed my cheek. "Go with it. She has been so lonely since dad left; I think she could use it." But she's your mom!" I protested, as Nancy started to suck on my balls."And you're hard as a rock, and enjoying what she's doing." She gave me a quick peck on the lips, and then said, "Consider this retribution for your evil ways in manipulating us." I knew she wasn't being serious with her.
