Now it must be known that Kevin wasn't gay and neither was Calvin but they were the greatest of rivals.
Calvin almost always won out when pitted against Kevin in any sporting event.
And Calvin wasn't a good sport about winning or losing. He rubbed his wins in Kevin's face and on the few occasions that Kevin won it was intolerable how Calvin treated Kevin. He could have been friends if they were just rivals but it was the way he won or lost that irked Kevin.
So when Kevin found himself and Calvin in the locker room alone he made a little wish to his penis and soon Calvin was rubbing up against Kevin's cock. As it got longer and thicker Calvin laid himself down on a weight bench that inclined at the top exposing his ass to Kevin's cock. As Kevin shoved his cock deep inside of Calvin his wish continued. Kevin's cock got longer and thicker till every bit of Calvin's pelvis was shattered. But it kept expanding and expanding till his ass could easily pass a bowling ball with room to spare. When it had expanded to twice the size of a bowling ball Kevin had wished Calvin's pelvis would heal in that form giving him what looked like an over exaggerated pear shape. His legs stuck out so there was a good foot and a half between his legs. He waddled, not due to weight but due to the position of his legs and the shape of his ass.
Calvin would never be able to win any event against anyone ever again. He couldn't control his bowels and wore a dildo strapped in to keep himself from dripping but the greatest humiliation was that he was pregnant with Kevin's child.
Now when Kevin asked his penis to wreck Calvin's ass the genie in his cock told him that revenge wishes had consequences and having a child with Calvin seemed to be the consequences of wrecking Calvin.
