Desperation clawing at him, our bound amateur struggles, muscles straining against the restraints. Sweat beads on his slim body as he fights to hold back the flood, but it's no use.

Loud moans escape as he finally relents, cumming hard into his hand, the room filling with the scent of sweat, piss, and release.
