T., I brought you something that I think will look adorable on you." He reached in his jacket pocket and pulled out a pale blue wool hat with the...M.I.T. logo in big and bold navy blue letters on the front. "Oh! That's so cute!" I squealed. He laughed again. He successfully put it over my wild hair and on my head, and smiled. "You look just as cute as I imagined." He lightly pinched the tip of my nose. "Thanks so much, Michael." "No problem, babe.

They're all I've got ..." I wouldn't say that," Rob smiled, pulling my upper body close to hisagain. "You have a lot more than just perfect breasts going for you."I giggled again, absolutely loving. My sister put her arms around my neck and kissed me as we came together, I fired streams of hot baby cum deep into her tummy as she groaned into my mouth the feeling making her cum as she milked every drop of cum from my cock with her cunt as we grunted into each other’s mouths. We stayed locked together kissing for ages as my cock went limp in my sexy hot, freshly filled little sister until she fell asleep on me snuggling up to me.After watching my sister doze off I wrapped my arms around her. Ironically, what made this experience even more deliciously-depraved for me, was the fact that I was seeing a counsellor for sex-addiction at the time and I got a huge kick out of divulging my sordid secrets to her, in explicit detail.
