Bound by chastity, our eager male masturbates relentlessly, unable to control his urge. He fingers his ass, stretches it wide, and lodges a colossal dildo inside. The toy's curve hits his prostate, sending waves of pleasure. He moans, writhing, as his cock leaks pre-cum. The cage can't contain his lust. He grinds harder, faster, and suddenly, he's cumming. But the cage holds, and he cums again, and again, until his abs glisten with his load.
