That night as we cuddled up to sleep she seemed to be spacing out so I asked if she was ok. She replied “what?” as if I had startled her or she ha... been lost I repeated my question and she smiled mischievously and said “oh I was just wondering when we'd have that 3some.” I returned her smile and in a joking tone answered “ I been waiting on the willing stranger to materialize and appear at our door.” We both laughed and tightened out grip on each other. Perhaps she wondered as I did as I. I was bucking my hips back onto to his big black cock.“The fucking slut loves it,” Steve said as he and Phil gave each other a high five. “FUCK ME FUCK ME,” I screamed out backing my pussy harder onto his cock.I felt my eyes roll up into my head. A strong and powerful orgasm came over me. My pussy gripped at his cock as my body rocked with my orgasm. I rather went limp as my orgasm rocked through out my body.“SHIT man the slut is coming on my cock,” I think Steve yelled out.I felt him slam his. I realised it was a girl fairly early on by the pigtails in her hair, she must be doing a bunk off school I thought as it was a Tuesday afternoon. She had her head down reading so maybe she was doing some study of woodland plants or something like that, maybe we could swap if she had any face photos. I did not want to appear to be sneaking up on the girl, that would be behaving like a dirty old man, or a voyeur with my camera. I deliberately made noises of someone approaching so she would not. Because of her nymphomaniac inclinations, she always used to tease me and my other male collegues: spanking our butts, “accidentally” touching our cocks, lots of indecent proposals…and more, no matter the age or looks. Just cock to be. All in all, for a working place, a real sexual harassment. But none of us was too bothered because of these little “games”, so we forgave her and none of us complained about this to the big boss. The funniest thing is that I wasn`t very interested in all that at.
