In the privacy of his bathroom, a hung stud, anonymous but for his meaty cock, decides to indulge in some solo pleasure. He's got a penis pump at the ready, and with a greedy gleam in his eye, he lubes up and slides it over his thick shaft. The pump hums to life, sucking and releasing, mimicking the tight, wet feel of a mouth or pussy. His breath grows ragged as he watches his cock swell and throb, veins popping out like ropes. When he can't take the teasing anymore, he removes the pump and takes over, stroking furiously. In no time, he's grunting, his abs clenching as he pumps out a massive load, the cumshot coating the tiles and leaving a sticky mess.
