Ben and Matt relaxed together one night, an evening of condomization followed by Matt showing off his swollen belly at the club had left the burly boy satisfied and sleepy. As he rested his heft on the couch, however, Ben was tapping away at his laptop.
“What are you working on so hard?” Matt said in half interest, scratching his massive gut. Most of his attention was focused on a movie he was watching, and he didn’t notice Ben had plugged the Chronivac into his laptop.
“Nothing,” Ben said, feverishly scanning a drop-down menu marked “Muscle.” After some more typing, he closed his laptop, stood up, disconnected the Chronivac and took it with him out of the room. “Bring me a beer while you’re up,” Matt called, not taking his eyes from the screen.
A few moments later Ben reappeared, and sat down next to Matt on the sofa. “Here’s your drink,” he said, a gentle grin on his face, and handed a cool bottle to Matt. Matt grabbed it and took a sip. “They sure loved me tonight, didn’t they?” He said, and gave his belly an appreciative grab. “We’re really living the good life.”
“And I think things are about to get a whole lot better,” Ben added, popping open his own bottle and taking a swig. He wrapped an arm around Matt and pulled him in close.
“I know we already did it tonight...” Matt said sheepishly. “But how about another load, big boy?” He reached out and gripped Ben’s oversized cock through his pants leg. The thing was already at half-chub and didn’t take much work to find. “It would be my pleasure,” Ben said. With the push of a button Matt was a condom again, and rolled onto Ben’s log of a cock.
Jerking off was much more difficult now that Ben’s dick was two feet long, but being stretched so far was indescribable to Matt. The aching emptiness he felt upon becoming a condom was filled completely, blowing far past satisfaction and into ecstasy. As Ben pumped, he grinned down at his boyfriend’s distorted shape wrapped so tightly around his giant cock. He felt his beanbag nuts tense, and started jerking faster. “Get ready for it...” he grunted. “Serve your purpose... to take my cum!”
With a loud splash, Matt ballooned outwards as he was filled with the biggest load Ben had given him yet. He immediately sagged from the weight, but even then it didn’t stop. Matt tried to cry out in pleasure as he was stretched even farther, but even if he could make a sound as a condom, his face was quickly pressed against the floor as the sheer volume of cum weighed him down to the ground. The flow continued, seconds turning to minutes as Matt started to wonder though the mind-numbing pleasure when the cumming was going to stop.
Suddenly, Matt could feel his hands on the floor again, and he blinked a few times as his vision returned. He was human again, his face still pressed against the floor. Suddenly, with a wet slurp behind him, he felt the shock of having Ben’s cock pulled from his ass, and the rest of his body slumped to the floor. He rolled over onto his back and smiled when he saw the flesh-colored mountain before him, if his belly was big before it was absolutely enormous now. Ben’s colossal load had been absorbed into his body and made him nothing less than a cum blimp. “Ben!!” Matt said excitedly. “You have to see how my—“
Matt’s eyes bulged in surprise as he spotted Ben. The man stood over him triumphantly, flexing and rubbing his arms, having suddenly packed on some serious beef. Satisfied with the results of his tinkering, he looked back at Matt and grinned proudly. His cock limp on the floor did nothing to diminish the sheer masculine power he was already radiating now.
“Damn, a whole twenty minutes, give or take... I knew it’d be a lot, but I didn’t think we’d run out the timer... What do you think?” He said, and continued posing. “I messed around with the Chronivac a little. From now on, whatever weight you gain from my cum, I’ll gain exactly as much muscle. That should keep you from getting too much of a swelled head next time we go out.”
“Um... I don’t know if I’m going anywhere like this,” Matt said, trying to lift himself from the floor. His girth was already turning out to be somewhat unmanageable.
“Well I mean if you’re not up for it, I could always hit the town on my own,” Ben said, and bounced his proud new pecs. “I definitely want to keep this going...”
