Make me ... feel like ... such a ... slut."I knew I couldn't hold out much longer, and was looking for a chance to take a break."Aggggh," she complain...d, when I pulled my finger out of her ass.I stopped thrusting. "Do you want me to put it back?" Hmmm." You'll have to tell me if you want me to put it back." YES, damn it! Put it back in, PLEASE!"The tip of my finger was no sooner back in her when she took over, carelessly ramming her ass back at me with abandon. All I had to do was to hold on. We are in our twenties now, both 5’4’’ 110 pounds, skinny with short dark hair and small elfin features. We aren’t completely identical of course, no one is I guess. Kirsten’s face is a bit narrower, her boobs a bit bigger. Everything else on our bodies is the same, and believe me we have gone over each other with a fine tooth comb many times. I remember the first night we hooked up clearly. It was after grad, we were both wasted, eighteen and high on life. We had gone to the school’s safe. I feel juice drip out of me as the sweetness of the sting arouses me even more.Using the nectar seeping from my flower, Doug wets his fingertip and presses into my rosebud. My tight muscle resists his gentle touch but stretches as he probes into me. I gasp as my ass sucks in his finger. I feel his finger stroke my smooth canal as my sphincter closes around him. He slides his finger in and out, picking up speed as he fingers me faster and harder. I moan and whimper as the pleasure makes my pussy. I was starting to get a funny feeling as I waited for her to come out. After a moment the door opened, and Jessica peeked out. “What are you waiting for?” she asked, waving me in, “C’mere.”I looked back over my shoulder to see if anyone was looking, satisfied that no one was around I went into the women’s room. The box of rubbers was on the sink and Jessica was still holding the cucumber. “Here, hold this for a minute,” she said, shoving the cucumber at me.“What the hell?” I asked, taking it.
