Two of my housemates, Tim and Cara were there too.I should explain. I live in a co-op with Tim, Cara, two other guys and one other women. We share a h...use not far from downtown. Tim is 6'3 and extremely handsome. With bright blue eyes and wavy brown hair, Tim is thin but athletic. Cara is taller than I am. She is about 5'8 or so, but we are both thin, so we often share clothes (that night she was wearing my Capri pants). Anyway, she's a blonde and I am a brunette. Since this is an erotic story.

I’m not gonna allow any of our boisterous Canadian crew to take advantage of Zupi’s lack of social skills.”“I’ll keep an eye out on things, Mike. I’ll make sure the other girls in our group don’t pressure Zupi.”“Thanks. I love you, both!” I said and wrapped my arms around their shoulders. When I eased off my hug, I began to walk towards the men’s restroom.When Lisa saw where I was headed, she grabbed my arm and said, “Here, we’ll wipe off your cheeks,.
