I have also had the occasional slap on the ass and liked that a lot. So as we emailed back and forth more of what he wanted started to emerge.I was to...wear some sheer to the waist pantyhose that were to be black. When I came into his apartment I was to immediately strip down to just the pantyhose, turn around and face the wall with my legs spread apart and away from the wall and put my hands on the wall. That was all he told me about the start and said I would get further instructions once. She stayed stubbornly still. “Alli, please…” She laughed. “Poor baby, so close, but so far away! Ooohh, look!” I looked; what she was drawing my attention to was the fact that my clear leakage had been replaced by a long, slow flow of milky white semen, like a slow-motion cumshot, which gently oozed out of me and ran down my cock and balls and over her fingers before dripping to the floor of the shower. It seemed to go on and on, like a gentle river, with no spurting or spritzing as it ran out. But then I thought about the sex vixen across the room, and I nodded.My girlfriend stood up from me sensually and grabbed Grant's hand, pulling him across the room as she sauntered towards Melanie. Grant, hard cock poking out in front of him, lunged forwards, groping my girlfriend's tit with one hand and yanking off her shorts with the other. Her juicy ass swaying, her big tits bouncing, Grant rubbed his cock against my girlfriend's thigh and dug his lips into her neck, making her tilt her head. She looked totally fucked out but for the bikers it was just a horny sight to see a well fucked-out Biker slut dancing while the cum running down her legs.The concert was over and the Bikers walked back to their chalet. On the way back they got a lot of compliments on their horny Biker slut.When John asked if she had any sense for more, she was a little drunk drunk so that she was still horny and it made her really not much out so she said, John, I've never enough! Again a couple of horny drunk.
