Internet Contact Provided His First Hard-Core MFM Approaching the door of the top-floor flat, having ascended four flights of stairs, I was slightly apprehensive, but very excited. I was about to be part of my first hard-core MFM threesome. The excitement of stranger sex added extra spice to the occasion. It was a warm summer afternoon, and I was certainly of a very sunny disposition as I looked forward to the excitement ahead. But I have to confess that I could have done without the four sets of stairs which separated the front door from my destination. I had previously had a three-in-a-bed scenario with a friend and his girlfriend, but that was more of a drink-fuelled scenario, with gentle fucking in the spoon position in the middle of the night, rather than full-on multiple-position hardcore action. The three-in-a-bed with my friends had just happened. But this was a planned and pre-arranged encounter with a couple whom I had met via the Internet. Kristen, a tall, sexy, slim brunette with 34B breasts, opened the door. She was dressed in an Agent Provocateur bondage-style outfit, which was more a series of thin black leather straps outlining her crotch and breasts, than a proper garment. Decorative rather than functional, its function was to tease and enhance, so for the purposes of its designated use, I guess it could indeed be described as functional. Kristen welcomed me, brought me into their living room, and introduced me to her boyfriend, Artie. I welcomed the opportunity to take a quick refreshing shower. Then I rejoined Kristen and Artie in their living room. Auvet had been spread on the floor. After a short chat, Kristen and Artie began their floorshow. I had intended to watch for about ten minutes, but within a minute or two I felt compelled to join in. After kissing and fondling Kristen all over her sexy body, Artie and I removed her skimpy leather outfit and her black silk thong, revealing her juicy shaven pussy. We alternated our oral and manual endeavors between her breasts and pussy, then added a rabbit vibrator to penetrate her cunt and stimulate her clit. With us guys standing and Kristen kneeling, she took Artie's seven-inch cock in her mouth, and I watched my first reality porn, up-close and personal, rather than on-screen. I had wondered whether I would be uncomfortable in such close proximity to another man's erection, but the situation posed no such problems. Such was the sexual frisson in the room. I presented my insistent cock before Kristen's mouth, and she proceeded to demonstrate her expertise in the art of fellatio. Then, switching from one cock to the other, the greedy girl sucked and licked our erections as if that were her vocation. We changed positions several times, and then with Kristen on all fours and her mouth clamped around my dick, Artie approached her peachy buttocks and inserted his member into her sopping wet pussy. There was no mistaking Kristen's pleasure. With a cock at each end, her spit-roast got under way. Wanting a close-up view of the penetration, I crawled under Kristen to get into a 69, with my face below her pussy, to watch Arties shaft plunge in and out of her lovely cunt, while I rubbed her clit. After some more switching, Artie reached his climax, and decided to allow Kristen and I to enjoy some one-on-one fucking. He left the room to let us play. For the next quarter of an hour, we indulged in some more oral sex in various positions before fucking in cowgirl, missionary and doggy positions. When we finished up, tired and sweaty, our orgasms were intense. . . .
