Jack was a gay guy in his late thirties, tall, sufficiently fit, with a broad hairy chest, brown hair, and a well-groomed beard that had always earned him the envy and at the same time the admiration of other men. That morning, to maintain his fitness and to vent the energy and stress accumulated after a week's work, he had taken his canoe and, paddling, headed into the heart of the lagoon that rose not far from his town. It was the middle of July, the sun was high in the sky, and after not even twenty minutes his tight-fitting, white sports shirt had already become completely soaked, highlighting vividly what was down there. However, his muscles, tense from exertion, continued to paddle vigorously even though copious rivulets of sweat had already trickled down wetting his swimsuit.
As the hours passed, the temperature reached 30C, which forced Jack now entirely soaked to look for a place to cool off. He thus decided to land on a small island formed by the tide. The sun was at its peak and there was no trace of shade but the lagoon water, though swampy and still, appeared as perfect for finding some refreshment. As soon as he disembarked, his foot sank into an ankle-deep ochre-colored mud but this did not disturb Jack's soul in the least; he had always liked the feel of mud on his skin and so, ignoring the grip, he slipped his other foot into the mud as well and stood up. The weight of his body made him sink down to his calves but allowed him to pull the canoe more toward shore to avoid losing it in the current that was created in the lagoon with the changing tide.
Lifting the canoe caused him to sink to his knees, and Jack realized that it would be a shame to muddy his own swimsuit unnecessarily. Unsure what to do, he looked around: he was completely alone. So he decided to take off his shirt and sit back down on the canoe and rinse his feet and remove his swimsuit to remain completely naked so that nothing of his clothing would be stained with that mud. His chest hair glistened in the sun drenched in sweat and his body slowly began to recover from fatigue. He rose to his feet and spotted on the opposite shore of the islet, a body of water that looked clearer. He decided to walk to it but after a few steps the mud suddenly became deeper. Jack found himself mired up to his thighs and when he tried to wriggle out he sank to his balls. An electric rush of arousal ran through his entire body: he had never felt anything so pleasurable.
Immediately he longed to sink deeper into that mud. He contracted his biceps and with vigor began to stir and activate the slime that surrounded him. The swamp began greedily to pull Jack's body down into its embrace and as the mud began to envelop his body and his cock he felt a mighty erection spring up from beneath the surface.
His cock, however, was not the ochre color Jack had expected as the mud stirred up with the movements of his arms had brought back a stickier black, pungent smelling mud on top.
Jack overwhelmed with excitement abandoned the idea of cooling off in the nearby body of water and began to move with his whole body trying to sink completely. The mud reached his navel, then his nipples and mingled with the sweat that his hairy chest was dripping.
As if in a trance, Jack made the mud reach shoulder height with his last effort and was completely enveloped by it. Never had he felt this way and never had he thought a swamp could turn him on so much. He slipped his big arms into the mud and with his right hand took hold of his throbbing penis. With a tremendous effort he began to masturbate as with each movement the mud enveloped his body a little more making him feel heavier. With his left hand he moved closer to his asshole and thinking back to his last intercourse he imagined how exciting it would be to be penetrated there by Mike, his boyfriend, in that black embrace of the swamp that left no escape. Pressing down on his ass with his left hand and jacking off with his right he exploded beneath the surface as by now the mud had taken him up to his chin mingling with his dark beard. He stayed there for a while, exhausted from the effort but fulfilled from the experience he never thought he would have. He breathed deep and struggled to pull himself out of the swamp as large lumps of mud slid down his beard, arms, pecs, and cock still enveloped in that black ooze. With a last effort he threw himself into the water and after thoroughly rinsing himself off, he dressed and began paddling home. That evening he would talk to Mike about it. He was certain that the experience with him would be on an even higher level...
