The gym is filled with the grunts of exertion, but the air is thick with a different kind of tension. Adam, the trainer, seems to be the only one aware of the subtle changes in his clients' bodies. He watches, entranced, as one by one, the straight men's cocks begin to swell, their shorts struggling to contain their growing lengths. He can't resist the temptation to 'adjust' their positions, causing them to blush and shift uncomfortably, their erections now obvious. The game of cat and mouse continues, the gym filling with the scent of sweat and precum.
