‘Anyway… We should get back to the dorm. I know you’ve got that programming assignment to work on, and I have some… stuff to do before I meet ...amien tonight.’ We walked out of Burger King into the driving sleet. It was frigid and wet and ugly out. Sophia latched onto my arm, staying close to me for warmth and balance as we walked. I couldn’t help but be excited, I knew I didn’t have a chance in hell with her, especially with that perfect boyfriend of hers, but that didn’t mean I wasn’t wildly.

With my hands firmly grasping one breast in each hand, I slowly plunged my penis into my sister’s clutching vagina, inch by inch, till I was completely buried in her.We lay like that for a minute, kissing hard as our bodies melded into each other below. Then, it was time to fuck. I started thrusting.
