Reaching back, he can feel his teammates cum dripping out of his gaping ass onto the tile floor of the locker room showers.  It gives him an instant hard on, but they have trained him not to touch his own cock, while they are in the room. So he stands there awkwardly, with a boner, massaging the cum back into his stretched out hole, waiting for them to finish their showers and leave, so he can stroke himself to the memories of getting gangbanged.
