Mixed-Gender Circle Jerk

I spotted an ad online where a guy was going to organize a circle jerk. Of course I responded with a degree of excitement. He sent the time and hotel room information where it was going to occur. I arrived ten minutes early. I couldn't help myself. The host greeted me at the door naked, with a good, solid hardon. He was quite tall, thin, fit, with long blond hair tied in a ponytail. He beckoned me in, and sat back down in the chair where he had been casually wanking while watching some porn on the TV that he had hooked to his laptop. I took off my clothes right away and laid out on his botel room bed, starting to stroke myself as I watched the totally typical porn along with him. I started to get hard, but not entirely. He, we'll call him Brian, and I talked. He has been married twice and is now divorced. He drives a truck for a living. He considers himself mostly hetro, but enjoys circle jerks. He isn't much interested in getting jerked, oral, or anything else by a man, but has the quirk that he really likes having guys cum on him. On his legs, or his chest and stomach. He says it dates back to his first wife who introduced him to swinging. She'd sometimes do things where other guys' cum would drip on him, and he found it very appealing. So now he likes to have guys ejaculate on him. We talked and watched the porn for about ten minutes when there was a knock on the door. It was a tall, medium built man named Marty, also about 50 years old. Brian introduced him to me as his "jerk off buddy." Evidently, whenever Brian is in town and in the mood, he and Mark place ads online and work out these circle jerks. They weren't sure who was coming. It might have been just the three of us. And that would be fine by me, even if we did nothing but stroke next to each other. I'm easily satisfied. I did make a mental note to cum on Brian, when the time came. As is typical with posting such events online, they had around 8 respondants, but quite often, many of them will get cold feet, or fail to show up for one reason or another. But no worries, there was another knock on the door, and in walked Sam. Another tall, fit guy, but perhaps a bit heavier than any of the three of us. He was well tanned - all over. We got to talking, and Sam said he likes giving head. I told him that whereas I'm mostly a handjob guy, I wouldn't mind a good blowjob. So, with me laying face up on the bed, and him face down between my legs, he went to work. And he was good. I did start to get fully hard. I worry about that. Sometimes, with a new person, or in a new setting, it takes me at least a half-hour to relax enough, or whatever it is, so that I can become fully erect. I suppose it is from a lifetime of trying to suppress erections at nude beaches, in locker rooms, and such. As he was sucking on me, another knock, and Brian let in Marvin, a shorter fellow who was also fit, and with an academic look. I felt quite bold to be receiving a blowjob as the door opened, and a strange man walked in, seeing me instantly. He too disrobed, and he seemed to be more of a voyeur, sitting on a shelf along the window in the little motel room. and just stroking himself while watching the porn on the TV, Brian stroke himself, and Sam giving me my blowjob. Marvin asked Bruce whether any women were coming. Bruce said no. Marvin commented that Marty had said possibly a woman might come. Marty interjected that he had indeed invited a woman, but he doubted she'd actually show up. Her name was Lori. It seems both he and Brian knew who she was, and seemed to have had some past experience with her of some sort. Just the thought that a woman could have showed up got me harder, and I had to ask Sam to take a break for a second so I wouldn't cum. I could easily imagine how cool it would be to have a circle jerk with a woman involved. That thought got me ridiculously horny. Another knock, and John arrived. He might have been around 70. Bald, tall, and also fit - fit for any age, but making 70 look great. Oddly, every man there was quite fit. I don't know why. I would have been fine with someone who may have been flabby or fat or whatever, but even happier that we were such a healthy group. The evening was going nicely. Sam had moved on to jerking himself. He didn't require reciprocation from me, even though i offered. John, on the other hand, seemed to like some attention from me, so I started in on him with a very gentle handjob. He stayed soft for a good five minutes and I was worried that he might just not harden up. But after a while, he became very hard indeed. I asked him a couple of times if I should do anything different - I had been alternating between ever so lightly touching his frenulum, then the tip of his dick, then actually stroking him in earnest a bit. He said 'no', that he was just totally enjoying what I was doing. Then, another knock at the door, and in walked Lori. A real, live woman! And good looking at that. She was only around 35 or so, and although not tall, and rather rounded, you wouldn't call her fat by any means. She was just built a bit on the thick side. Or maybe not. I mean, her ass was small and tight, it's just that she had big, gorgeous boobs, with pretty pink nipples. She had olive skin and long black hair, like a southern Italian model. Lori started taking off her clothes, and I was suffering from great amazement. Was this woman really going to join in our circle jerk? But no, she stopped removing clothing at a sort of one piece swimsuit-like thing. She hugged Brian and Marty, and then kind of sat innocently in Marty's lap pressing his impressive erection against his belly. I asked what she particularly enjoyed, and she said she loves watching men jerk off. OK, I could be happy with exactly that! I do have a bit of an exhibitionist streak. We all talked a bit, then she stepped out of her little suit, and was totally naked, just like all of us. But not like us at all. Every time I looked at her, I got electric shocks throughout my body. She had a small, thin patch of black hair on her pussy, and at one point, as she changed her position, I got a glimpse of her dark, puckered asshole. This was while Sam had resumed blowing me, and by God, I lost it. I came! I could have prevented that if I had been thinking more clearly. I wanted to tell Sam to stop, but I got confused and called him Brian, and so he didn't respond, and kept going, so I came. But no problem. The evening was just too good for me to wilt away into nothing, although for a few minutes, I considered going home early, and it did take me a while to get it up again. Lori started getting more involved. She started handing out blowjobs like they were candy on Halloween. At the same time, she was gently pushing a tiny little vibrator against her vagina, which had a fairly rapid effect on her. She was squirming in delight. In my limited experience, it is a very rare woman indeed, who can feel free enough to be like this in a group of men, most of whom she didn't know. At one point, she was sucking on a happy guy while laying with her upper body on the bed, but her knees on the floor, giving me a delicious view of her beautifull, dark butthole. I love looking at women's assholes. I can't explain why. Even more, I love playing with them, given the opportunity. I just went ahead, reached out, and started rubbing my index finger around her anus. I was concerned she might not like that. I was preparing to be embarrassed if she told me to stop that. But my attention had an immediate electrifying effect on her. She started bucking, and pressing her butt back to get my finger to start penetrating into her. So I did just that, pushing it farther and farther in - ever so slowly, while stroking myself with my other hand. My recent ejaculation was forgotten, and I was getting all hard and horny again. And she was having a grand time also. She seemed to have forgotten the guy she was sucking as he then backed away, and while I pushed my finger all the way into her butt and pressed lightly this way and that, she went crazy! That sent her into a crashing orgasm. The evening wore on. At various times, pretty much all the guys sucked her tits, ate her pussy, or got a blowjob from Lori. Sam came when she blew him, and because our host Brian had said he likes having cum on his body, he pulled out of her mouth, and squirted some of his sperm on Brian. Shortly after, Sam dressed and went home. Now, John and the others had got involved also with Lori, trying do with her pussy what I had done with her asshole. I think a lot of guys don't realize that in some circumstances, a woman can derive even more joy from the one opening than the other. She announced that she wanted someone to cum on her tits. I was ready, and so I voluneteered. She was having a great time getting what appeared to be three fingers simultaneously, and I started stroking over her chest. At the same time, suspecting she wanted more butt action, I pushed my finger back into her butt, and she had another crashing orgasm. That sent me over the edge, and so I came on her tits. She then climbed on Brian, spreading my cum onto his chest, which seems to have made his day. Like all good things, the evening came to an end. We all thanked Brian on our way out. He told us that he was very pleased we came, that he thought it was a very successful evening, and he plans to do it again in a month. He'll drop us an email the next time he's coming to town. We also thanked Lori, who turned it around and let us know that she was very, very happy to have been with us.
