The twink's uncut cock throbs with need as he relentlessly teases his foreskin, pushing himself to the limits of endurance. His muscles flex and tense, his body aching for release. He bites his lip, his breath ragged, as he struggles to hold back, but the tension becomes too much. With a guttural groan, he surrenders, his uncut cock pulsing as it coats his abs in hot, sticky cum.
