I have always known both of my roommates to be very affectionate with one another, and I also know them to be very sexual and outgoing. However, I never knew how close they *really* are until one Friday afternoon when I came home from work early.
It had been a very light day at work, and as I had put in a great deal of overtime earlier on in the week, my supervisor told me to go ahead and knock off early. I was quite pleased and was hoping to find my roommates at home...perhaps we could all go celebrate.
I unlocked the door and headed upstairs to change clothes, noticing that neither of my roommates were anywhere to be found downstairs. As I walked up the stairs, however, I heard some strange sounds coming from Shelley's bedroom. Her room is at the very top of the stairs, and as I approached the landing, I could see Shelly, completely naked, straddling someone on her bed. Needless to say, I was very surprised, and as I tried to sneak into my room, I realized that Shelley was straddling my other roommate, Kara!
I was completely shocked...all I could do was stand and stare as Shelly rocked her hips, grinding herself into Kara's naked mound, with her head thrown back and moans of pleasure escaping her lips. Just as I realized I was staring, Shelley looked right at me, smiled, and began to orgasm. Even as the orgasm rocked her body, she never lost contact with my eyes, which were glued on her lovely naked form.
