Kyle grinned at the enhanced twins and then turned his attention to the rest of the party.
"Now that the twins are properly equipped. Let's play a game!" He said with a showman's flair, "The winners of the game will get to make a request. The losers, well, depending on how hard you try, that'll be up to me."
"Cain twins, your goal will be to outlast each other. The first to come loses." Kyle said.
The twins looked at each other with a competitive glint in their eye. Each wanted to be the one to determine their little brother's fate. They could help him out, make life easier for him, or they could help themselves by changing him. Considering he was the reason they were here in the first place, a little justice might be due.
"Now," Kyle said, "I need two volunteers. Just by volunteering, you'll each get a reward but the winner will get to make a request."
Tyler Meadows, a receiver on the football team raised his hand with a little hesitation. He was quickly followed by Michael Royce a member of the swim team.
"Players come on down and choose your partner." Kyle beckoned with a showman's gesture.
Tyler took his place in front of Dan and Michael in front of Dave.
Kyle addressed his volunteers, "Lets make this more enticing, you're both stripped down to your jock and speedo."
Instantly, both young men were wearing only the bare minimum. Neither of them even tried to cover up. By now, they'd seen too much. Tyler's ass was nicely framed with the straps of his jock, his farmer's tan on full display. His opponent was in his school speedo, his body relatively devoid of tan lines except for a bit lighter area in his thighs that showed he sometimes wore the trunk speedos to practices.
Kyle walked around the four participants. Explaining the rules. "The twins will stand side by side, shoulder to shoulder and it will be your job to get them off. The first one to get their twin to cum will be the winner. You're free to do whatever it takes to win."
Both Michael and Tyler seemed to shiver with disgust but they remained silent eyes on the request that might get them out of this hellish party.
"Dan and Dave get ready!" Kyle said, "Tyler and Michael get in your starting positions!" Both volunteers dropped to their knees in front of their twin.
"Ready, set GO!" Kyle shouted the word Go with such enthusiasm that it took all of them by surprise.
Tyler got to work, grabbing Dan's meaty shaft with his large right hand and working it as he rolled the massive balls around with his left, working with pace and rhythm. Michael didn't. Instead of starting to work on Dave's cock, he sprung up and went to where the younger Cain brother was standing and slicked his hands on his still dribbling cock smearing the aphrodisiac liquid all over his palms and fingers. He returned in front of Dave with a raging boner in his speedo from his contact with the stuff. He began to work Dave's shaft panting from both his effort and his own arousal because of Cain's pre.
Tyler noticed his opponent's actions and began to work harder. With a disgusted groan, brought his mouth up to lick the tip of Dan's cock. Dan gave a low moan and placed his hand on the top of Tyler's head. Tyler hated it. He hated everything about it but he kept going because he knew if he worked at it he could at least make a request and not end up like Cain or Chad.
Michael also began to lick the cock before him. He didn't want to and wasn't excited to but the smell of Cain's goo was just too good to pass up. He greedily lapped at the substance with much greater vigor than Tyler had mustered.
Both twins were getting close. They were holding back but their earlier encounter with Cain and the growth in their organs prior to the match meant that each of them were on edge from the beginning.
Dan wanted to win though and so he decided to break Dave's concentration. With a gasp, he got the idea. He watched as Michael brought the wide top of his brother's head into his mouth and as his brother bucked his hips, Dan slapped his ass.
That was all it took. Concentration was broken and Dave shot his load. The first blast filled Michael's mouth and he recoiled. The rest of the spurts hit him in the face and chest. Dan quickly came but Michael was able to dodge the load. The two guys in the front row in front of him had their shoes and ankles plastered with the spunk.
"Michael wins!" Kyle shouted.
