"Shit!" he exclaims, rubbing them with his finger. They're so big! How's he gonna hide them from his mates?!
Frowning, he moves away from the mirror, doing his best to force his lips shut (no easy task!) and then jumps as one of his crewmates races in, his eyes wide, his right hand clamped to his mouth.
"What's wrong?" the first lad mumbles, momentarily forgetting his condition.
"My teeth!" the other answers, rushing towards the mirror. "Something's wrong with my teeth!" Lowering his hand, he leans over the sink, peering closely at his reflection. "Jesus!" he exclaims in horror, "What's goin' on?!"

The seat of his shorts now bulged considerably, and eagerly he gripped the stiff, throbbing protrusion, squeezing and working it.

The front of his white cotton shorts looked like Mount Everest!
"Oh man!" the other moaned. "This is SO good!" With one hand squeezing his pulsing tail, the other went to work between his legs. "Come on, Joe, " he exhorted his wide-eyed friend, "You gotta do this too...."
