As Luke waddled out the locker room he come up to James. James is the forward for the team and very familiar with Luke.
Dude what the hell happened to you? James queries.
Don't know but damn look at this thing.
He pops open his pants and drops that sucker to the floor.
James is stunned by the look and in that few moments of shock Luke spins James around and drops his pants as his cock is hardening.
If there had been anyone else in the area they would have heard a high pitched scream and would have sworn it was a girl. But James had never been fucked by a man and in fact never had sex with a girl. He was confused by his orientation but as that python made it's way up his back side Luke just kept thrusting.
It took over an hour of thrusting for Luke to come to a climax. James passing out from time to time from sheer exhaustion. But when he came he felt every once of the sperm enter him.
James was pressed against the lockers but as he filled with Luke's sperm his belly rounded out and pressed him away from the lockers and even deeper onto Luke's cock.
As Luke finished he noticed that his watermelon sized balls had returned to his normal egg sized balls and that every ounce of his sperm was deep inside of James.
Luke spun James around and patted him on the belly. Damn look at that. Neither James nor Luke could have expected the next revelation. Not an ounce of sperm escaped James' ass. Like some other animals his sperm formed a mucus plug and it held the sperm inside of him. And although Luke wasn't waddling because of his huge balls his cock still made him walk funny and it would take a week to build up the watermelon sized balls again. He had wondered if James was still plugged if he could fill him again because he really liked this huge belly on him and if he was able to release the sperm by that time he wondered if he waited if his balls would become bigger and he could really fill James. And even though James didn't have the equipment he wondered if his new body would impregnate James.
