"What was that you said?" Marty asked.
I didn't answer, but I opened my mouth and turned it toward Seth's dick and took the bulbous head in. I licked and sucked, and Seth gave little whimpers of pleasure. "Get your tongue under it," he said, and I complied. He entered me about three inches and I thought I'd gag. "Don't think gag," he directed. "Lift your chin to give it a straight shot and push your tongue and under it as far as it can go. And open wide, very wide. Loosen your jawbone. You can do it." I did so, and he slid in a little farther. Then me began to slowly pump in and out, fucking my face but not trying to give me more than I could manage.
Meanwhile, down below, Marty had withdrawn his prick most of the way and was pushing back in. He reached my prostate again with his cock and he was rubbing up against that and giving me a not-unpleasurable sensation. Other than the one painful punishment thrust, he hadn't been doing more than slowly working his way in at this point, holding for me to stretch to be able to accommodate him. After he had gotten past the sphincter, I no longer felt great pain and the sensation of being stuffed beyond limits, and shortly I could feel I had loosened and relaxed and a felt the whole length of him glide on in. I could feel his pubic hair mashing down on mine.
"There," he grunted, "you did it. You did fine. You've got one sweet, big ass channel." He didn't do any pumping at that point, but he did move his pelvis around, rotating his cock inside me. My prostate liked that just fine, and it served to loosen and widen the canal some more. He came back up on the hot tub seat with his knees, so that now me was hunched over me. He pushed my legs down toward the deck at an almost impossible angle, so that now we was hovering over me, with his ramrod almost on the vertical.
It was then that Seth jerked out of my mouth with a grunt and spurted cum all over my chest, and as that happened, Marty began his pumping action in my ass. In and out, short strokes and then long strokes. Wiggling his pelvis and rotating his dick around, stretching and filling me. Seth changed positions again, without me being able to escape. He turned around on me, putting my head firmly between his knees and kneeling there. His hands went to my dick and my balls. He played with the balls for a while and then got hold of the cock and started stroking and pumping it. He and Marty did some kissing without letting it interfere with their other activities. And then I felt lips on the tip of my cock, and Seth took me on to the root in one slide, showing me that, indeed, it could be done. In turn, I showed him I wasn't taking any of this passively. I pulled his butt cheeks apart and started tonguing and rimming his asshole. I then fisted a hand and started pushing the knuckles at his hole, and, to my surprise, they started working their way in. Seth's only response was to wiggle his ass in pleasure, which I increased by taking his dick in my other hand and starting to milk him.
Marty, Seth, and I came at just about the same time, and, with a combined scream of release, followed by a sigh of relief we all were back in the hot tub, soaking away body fluids. I wasn't really in any condition to look where I was going, however, because when I went to sit down on the hot tub ledge, Seth was under me. I struggled and objected, but he had only of those beefy arms around me and the other was on his dong, which he guided to my newly plowed asshole as I came down. I managed to stop, at first, when helmet of his cock was just at my entrance. But Seth held me there steadfastly and slowly, ever so slowly, my leg muscles gave way and I descended down his gigantic tool, feeling every inch in both length and diameter as I was skewered until my butt was nestled up against his upper thighs. I panted and moaned, while Seth clucked sweet nothings in my ear and nibbled at my neck.
"Oh, Gawd, no, Seth. You're too big. Let me go," I whined.
"You've already taken me in, Glen. From here, just take it and enjoy it. You now know there isn't anyone you can't take. I'm ten inches long and mighty thick, Glen. There aren't many bigger than that. Just relax. That ointment we used is good stuff, and, as Marty said, you've got one incredible ass canal."
When I had stopped panting and groaning, Seth pulled my knees up and into my chest and began gently rocking from front to back. His rock-hard, yet flexible dong was rubbing my prostate and other nooks and crannies up my ass channel in a way that gave me a whole new sensation, and I found that I could accommodate him without pain now. I was lulled into a sense of relaxation, but the two weren't finished with me yet.
I had about dozed off in exhaustion, when I felt Seth standing up. He still had me folded into his chest by the knees, and he bore my weight as if I were a rag doll. He didn't go far, however, he just moved up to where he was perched on the rim of the hot tub. That's when Marty came back into view. Seth leaned back so that my butt was lifted in the air and there Marty was, with more ointment, and spreading it around my now-occupied asshole. I don't know how he was doing it, but he was managing to get a few fingers into the hole above Seth's buried dong.
"What are you doing?" I cried. "Oh, no, not that."
"Such a sweet hole and channel, Glen," Marty cooed. "And so flexible. It opened right up. More than I thought possible for a first time. Have you and your wife been playing rear-entry games? Don't do anything rash, Glen. Just hold very still there, for me . . . and for your sake."
And then he did it. I felt the head of his cock at my hole above Seth's rod and slowly, ever so slowly, he was entering me as well. He was half way in when he slowly pulled out again and then in, a little farther than the first time, and then slowly out and slowly back in. Seth was giving little yelps of pleasure at the friction Marty was bringing to bear on his buried cock between kisses he was enjoying with Marty. His cock began to do some involuntary pumping as well. I passed out before they were finished.
