Sci-Fi Story - Ad Man 4

He was out of control with the thrill of what he saw and what was happening. He couldn't wait to get like Larry. He couldn't wait. And suddenly, without a stroke, his groin exploded with the start of an orgasm that radiated through his body, contacting him into a total body spasm that traveled back into his groin, down the length of his wonderful cock and finally rocketed him into space, a space he never even imagined possible. He thought his joints would fly apart as he shot volley after volley of hot, thick cream, jerking with ecstasy as it hit the mirror so hard it splashed all over him and Larry. And it just kept coming, and coming, pumping up from some place so deep he didn't know it existed. It hit him in the face and all over his chest and stomach.

He saw it hitting Larry, matting the hair on his gargantuan chest, plastering it down as it ran down his abs. Finally, after what must have been more than a minute of full ejaculation, it slowed and stopped. Larry was laughing, rubbing the cum into his hair, massaging his tits with its slippery lubrication. Tucker did the same, taking his lead from the hunk beside him. He felt so good, his body felt so good under his hands. His cock was still hard, still, to his amazement, throbbing, wanting more sex.

Then Larry reached for him, pulled him over, and began to massage the sticky fluid into his pecs and all the way down his abs. As soon as Larry touched him, he knew he had waited his whole life for this. He sucked in his breath and Larry leaned forward and placed his mouth on Tucker's. The feel of a firm mouth surrounded by stiff, scratchy whiskers made him suck his breath in again, almost to the point of fainting with passion, and he felt Larry's tongue press in to explore. He let himself lean hard into Larry's body to hold himself up, felt his pecs press against the hard, enormous mass of Larry's. He felt Larry's huge cock find his abs and start to work up them as they moved closer together.

Then his own cock touched Larry's pubic hair and the base of his dick. Larry pulled him closer until both their cocks were pressed between their rock hard bellies, rubbing against each other, stimulated by the hair on their bellies. Tucker felt almost weak, swept into a tide of erotic, male passion. Larry kissed him hard, moving from his mouth and pressing his lips and tongue into the soft flesh under Tucker's jaw line, his chin, sucking on the cleft in his chin, working it with his tongue, then down his throat to his chest, where he buried his face in Tucker chest hair, licking deep into his cleavage and cuts, sucking and nipping at his nipples. He grabbed Tucker's hard, round butt and pulled him closer still, pushing their groins hard together. Then, before Tucker knew what was happening, Larry had wet his fingers with Tucker's spunk and was working it between his buns and into his asshole.

Tucker realized what Larry intended to do, and there was no way he could make himself want to stop him. He was so hot and so horny that he wanted more of everything, wanted to do, to know everything that could be done with and to the male body. He worked on Larry's pecs, massaged them hard, pressed the heels of his palms into their dense mass, lifting their incredible weight. He couldn't believe his own would soon be this massive, and he couldn't wait to feel it on himself.

Larry turned him around, reached under his arms, around his lats, and grabbed his pecs to pull him close from behind. Tucker felt the head of Larry's cock against his butt, pushing between his buns, separating them with its fist-sized head. He was so hot he didn't care how much it hurt; he wanted to feel Larry deep inside him. Larry was telling him how hot he was getting , how big. He told Tucker to flex for him, and Tucker felt hot and powerful as he raised his arms in a double biceps. His arms were getting huge. He looked in disbelief at the size of his biceps, how they peaked. He heard Tucker saying what great fucking arms, what great fucking tits, as he massaged his pecs harder. And then, with a slow, deliberate thrust, Larry was inside him. He slid the entire length of his cock in, slowly, filling him, deeper, deeper, until Tucker felt himself stop against the dense hair and hard flesh of Larry's groin. He closed his eyes and a groan escaped his lips.

Larry held him there for a minute, not moving, just pressing himself hard into Tucker. Tucker felt the fullness of Larry in him. Then Larry slowly moved his hands down Tucker's torso, across his swelling, growing muscles, until he had taken Tucker's cock in his hands. As he slowly began to stroke the length of Tucker's cock, he withdrew himself and pressed himself back inside Tucker in the same rhythm. He gradually increased his tempo, withdrawing himself slightly more each time, until he was pulling out past the rim of his cockhead, feeling the flaring edge pop out and back in again, slamming Tucker's hard ass each time he rammed himself in to its full length. Tucker felt the heat increase until he felt white hot.

His moans became open mouthed groans, increasing in volume and intensity with Larry's pounding rhythm. He felt Larry's breath, hot against his neck. He was nearing orgasm. He could feel it building in him until he felt himself rocked by another nuclear explosion, like before but stronger, squeezing him to the center of his cells, his body alive with pulsing, shocking, jolting sexual electricity. And as he watched thick streams of white cream jet out of his cockhead he felt Larry inside him jerking hard, convulsing with his own release, filling him with hot juice. He felt himself fill up until Larry's cum was leaking out and running down his butt and dripping off his balls.

When their convulsions finally subsided, they both collapsed on the floor in the pools of their cum, laughing, rubbing handsful of it onto each other, plastering down their hair, slipping and sliding their hands over each other's incredible muscles. Larry suggested a swim in the pool, and they went out to his patio. Tucker felt magnificent. He could feel himself still steadily swelling bigger, harder, denser, his body hair filling in, his dick and balls growing more and more like Larry's. Then, suddenly, he felt his muscles start to cramp. Deep in his bowels, where he had taken Larry's load, he felt heat building and radiating.

It felt kind of good, kind of sexy, but it also felt strange. He felt his muscles draw into themselves in a deep, but not a painful cramp, and then relax for a second or two, and then draw up again, almost like mild convulsions. He told Larry how he felt, and he went to the side of the pool where he could stand and lean against something for support. He laughed at himself for reacting, but the feeling of convulsing grew stronger, even though he was not outwardly convulsing. He looked at Larry watching him, and he saw amazement, maybe fear in his friend's eyes. And then he knew what was happening. Somehow, taking Larry's cum must have increased the activity of whatever was causing his transformation.

The rate had increased. He was growing so fast he could see it, and so could Larry. He could feel it. Suddenly he was on a rocket. He could feel his arms getting thicker and heavier, even as his lats flared and pushed them out, up. His pecs were ballooning inside his skin, broader, thicker. They were growing so big so fast he thought his skin would split. He could hardly see over them. He could feel his butt, where he was leaning, growing bigger, thicker, harder, literally pushing away from the side of the pool. His thighs pushed away from each other as they grew bigger and bigger, until he had to bend his knees to stand.

His cock throbbed, reaching a spontaneous orgasm again, spraying his cream into the pool. He heard himself saying Oh, God! Oh, God! Oh, God! over and over again. And his orgasm didn't stop; he just kept shooting spurt after spurt, and his cock kept growing, bigger than Larry's. He could feel the weight of his balls against his thighs, almost to his knees. He had to see. It was hard to get his arms around the mass of his torso to reach them, but he lifted them and they were bigger than Larry's, too. They were the size of softballs. He wished he could get to a mirror. He knew he was bigger than Larry all over, and he was still swelling, exploding with mass. Christ! This was incredible! Would he be able to walk?
