You can sense the burning lust that's growing inside Coach Zeb - one look at the crotch of his pants is all it takes. Slowly, he unzips the front of his track suit. Underneath, he's wearing a shiny latex suit - like an elaborate version of the one the team had on earlier. He pulls off his pants as well, and tosses them aside. He stands in front of you, in the shiny bodysuit, which conforms perfectly to his body, even his raging, erect cock being perfectly encased in it. His muscles are impressive, outlined under the shiny material - he's easily as big as you, you guess.
You take a step back, a little overwhelmed by what's going on. Coach Zeb just chuckles, a low, deep rumble. "Very hot there, boy. Making me very, very horny..." You can see his skin turning red, veins starting to show, even a few under the latex... And sweat beginning to drip down his temples. "Ohhhh... yeah...." he groans, his voice deepening slightly, as his body begins to throb and swell, his muscles getting bigger with each heartbeat, his height slowly increasing, his frame becoming wider and thicker. You take another step backward, your legs bumping against a bench. Zeb's laugh returns, deeper and thicker, as the latex thins, being stretched by his massive body. Even Coach Zeb's cock is getting bigger, as are his latex-encased balls, the big fucktool throbbing obscenely.
You're shocked and frightened, and turned on all at the same time. Your own dick is hard as a rock, watching Coach Zeb turn into a freakish musclebeast, a seven foot behemoth, packed with what looks like five hundred pounds of solid muscle. He's breathing heavily, his massive chest straining the latex, each striation of his monstrous pecs clearly visible, his nipples thick and jutting. He looks down at you and your cock and grins. "Like what you see?" he rumbles, his voice so deep and sexy. You nod slowly. He laughs, and steps up right in front of you, his huge tool pointed at you. "Give it a good lick..." he purrs, his voice so deep and resonant, you can't help but lean forward, bending over to take as much of that huge, latex-covered muscledick into your mouth. You lick it slowly, feeling it throb under your tongue. "Oh fuck yeah..." Zeb groans, his big hands moving to the back of your head, holding you in place as he starts shoving his massive rod deeper into your mouth and throat. You gag on it, but he doesn't let up, his already big cock growing larger and harder as his excitement rises.
Just as you think you're going to pass out from having that massive tool shoved down your throat, Zeb pulls out. You stare straight ahead with blurry eyes, his monstrous musclecock filling your vision. Your focus returns, and you look up to see his immense body, bigger and freakier than before. He grins at you, and grabs you with both big hands, hoisting you effortlessly into the air. "Hope you got that cock nice and lubed up, 'cause Coach is feeling like giving that nice ass of yours a ride!"
You moan in response, as you feel Zeb's huge prong nuzzle at your ass. It's so big, so thick... you wonder how it will ever go in. But then Zeb starts pushing you down, down on his monster cock, slowly forcing it up your tight, muscular ass. You cry out, in pain and pleasure, producing deep chuckles from the huge brute. He pushes in further, harder, and you can feel it hit deep inside, as he gives one more brutal shove. You cry out, but your voice is drowned out by his roar of pleasure and domination. He starts fucking you in earnest now, pumping his big stick in with hard, quick strokes, driving your prostate wild. Your own dick is hard as a rock, and after a minute of mind-blowing stimulation, you cum, all over the shiny latex covering Zeb's brick-like abs. He grins at you in satisfaction, and seems to redouble his efforts, fucking you harder and more brutally than before, using his massive body to full effect, pounding your ass with his throbbing musclecock. You feel that massive tool swell even larger inside you, hard as stone, and then he comes, head thrown back, roaring like a wild animal, still pounding his big dick as he explodes. His entire body seems to flex all at once, getting bigger and freakier, and the thin latex seems to tear in several places at once, no longer able to contain Zeb's freakish mass. You can feel his hot, thick cum fill you, as the latex suit seems to fade away to nothingness, disappearing entirely.
