Another party, another cellar - Part 3

I stayed in the sling for about thirty minutes and enjoyed every second of it. My young friend did go first, and he felt delicious. Then he slipped off his rubber and moved round to stand by my head so I could suck on him. While I did this, my earlier pool friend suited up and took his turn in me. Two other very hard guys were standing close by and watching our show. They were stroking unashamedly. My pool friend was clearly going for it, he was pumping me hard and deep. One of the wanking watchers stepped in and started sucking me. So now I had my ass filled, a cock in my mouth and my own being sucked. Sex was all around me! Then I could feel pool friend jerking as he came hard inside me. He groaned as he released his load, before pulling out. The second wanking watcher then took over his position. I looked up at my young friend who winked and smiled, indicating the new guy was following the rules. New guy was nearer my own age, and like me his cock was about eight inches and quite thick. He took it slower as he pushed inside. The guy who had been sucking me started sucking on new guy's nipples which he really seemed to like. I soon managed to relax and take new guy inside fully, and he got into a nice rhythm. I can't explain it but the sling really helped with how we were fucking, there was no awkwardness at all. Gravity was taken care of, and though the sling moved from side to side, it's design gave us stability to pump. When new guy started to get close he pulled out, slipped off his rubber and after a few strokes with his hand, sprayed his load over my belly. To my surprise my young friend who had started the ball rolling clearly wanted more as I could see him preparing. Before I knew it he was back inside and pumping away. My wanking watcher went back to sucking and stroking me. Now, I can take a lot, I can sometimes edge for hours. But this guy was sucking hard and I knew I was going to blow soon. I wasn't going to fight it, in fact in that sling i couldn't. I love cumming with my ass filled, it's so intense. When the first spasms hit me it made me writhe and jerk against the restraints. My sucking pal took a mouthful and let the rest shoot up into the air. My young pumping friend slowed his action as he watched me explode, and whistled his approval. I never did see him shoot his load, I'm sure he had plenty more fun that day. He pulled out and let me relax a little before helping me out of the sling.
I eventually made it back upstairs and remember gasping in some fresh air when I reached the garden. It had been a great party and although I never made it back down those steps that evening, I would do it all again in a flash!
