I'm a 28 year old bi guy, fairly slim and straight acting. I've been meeting guys off here for a few years to suck them off, letting them cum in my face and hair, or in my mouth (though I never swallowed unil recently). I recently registered for a different site in addition to this one, and have had quite a few experiences with a guy I met on there. The first time we met, we had been speaking on MSN about how I wanted the evening to go. I had been gagging to get my ass fucked for quite a while, and the guy seemed keen to be the first to do it! He lives very close indeed, walking distance in only a few minutes (which has turned out to be quite useful for short notice meets). I had made an excuse to my girlfriend (who is unanware of my activities) so I could get away for the evening. When I arrived, as arranged his door was unlocked and he was nowhere to be seen. On the ground just inside were leather wrist and ankle cuffs, and a collar with written insructions on what to do next. I was to strip naked (I had trimmed my body hair as he liked his men as smooth as possible, I couldn't shave completely as my girlfriend might get suspicious), put on the restraints and wait for him 'in a position he would like to find me in'. I stripped down, made a bit of a botch at putting the cuffs and collar on, and waited kneeling on the floor. He came down from upstairs, gave his approval and showed me up to the bedroom. He was quickly naked, guiding me down onto my knees so his rapidly stiffening cock was at face level. It looked great, and as I sucked it greedily, imagining how it would feel stuffed into my tight virgin arse he looked down approvingly. 'You've done that before', he said. 'Mmmhmmm' I nodded in agreement, my voice muffled by his hard cock. He led me over to the bed, where there were chains attached to each of the 4 corners so the cuffs could be attached. He lay me on my back, sideways across the bed, and attached the cuffs to each corner, splaying my legs wide with my head hanging upside-down slightly over the edge of the bed. A few guys I'd met before had used my mouth this way, though I'd never been tied down before! He straddled my face, positioned his cock at my lips, and started thrusting in and out of my mouth. I was moaning with pleasure, struggling against the restraints whilst trying not to gag on his length as he thrust it deeper. When he'd had enough of this he pushed me forward, so my head was back fully onto the bed. He reached into his bedside draw and took out a dildo, not a scary massive one or anything, and rolled a concom onto it, explaining he would be using it to open me up a bit. He went round to my feet and unclipped the chains from them. He lifted my legs up in the air so my bumhole was fully exposed, and started licking. I was gasping as his tongue darted in and out of me, and around my hole, the feeling was so intense and seemed to go on for a lifetime. I felt him squirt some lube on to my hole, and he started working it in and around with his finger, probing deep into me to spread it as much as possible. Next thing I knew I could feel the tip of the dildo nudging against me. The work he had been doing down there seemed to have done the trick, as it slipped into me easily. I moaned as he moved it in and out slowly, checking to make sure I wasn't groaning with pain. I assured him that I wasn't! He moved back around to my head so I could lick and suck his cock and balls as he did this. As is licked around the bottom of his balls, the urge to return the favour he'd done me earlier overcame me, and I moved my head slightly so I could get access to his hole. Today was certainly one for a lot of firsts! He appeared to enjoy that immensely, and soon he was rolling on a condom, lubing his hard cock up and removing the dildo. Again he lifted my legs in the air, and I felt him slide in easily and start up a rhythm fucking me. I struggled against the arm restraints, squirming and attempting to rock my hips to get him in as deep as possible. It felt great, lying there with my legs in the air, helpless, finally getting the fucking I had been longing for. All too soon he had to slow down to avoid cumming. He pulled out, took off the condom and unchained my wrists from the bed. I was moved so my head was at the top of the bed, propped up on a pillow, and all the chains were put back on, ankles included. He straddled my face and began fucking my mouth again, looking down at me as he did so. He started wanking his cock whilst I licked his balls for a bit, and soon he was ready to cum. We had agreed that he could cum in my mouth and I would make my first attempt at swallowing, but he was just a split-second too late getting his cock back in and he shot his load all over my face (I wasn't disappointed, this is my favourite way to take cum!). I sucked his cock gently as it softened, trying to get as much out as possible, getting a little bit to swallow, but most of it was plastered from my lips up to my eye. He unchained me, I cleaned up and we agreed to do it again soon. I had a few red marks where the collar and cuffs had rubbed during my struggling, but fortunately my girlfriend didn't notice! My ass wasn't sore or anything, I was amazed at how easy it had been, and he commented that first-timers are usually a bit more difficult to get into. We've met a few times since then, I've swallowed his full load now (yay!) and soon he's going to arrange for another man to join us so I can live out my fantasy of being spitroasted (can't wait for that one!).
