Pervysage503 pushes their limits in this cock-ring endurance test. The tight band of rubber around the base of their engorged cock keeps the blood flowing, maintaining a constant state of arousal. They stroke, tease, and torment themselves, the shaft glistening with pre-cum, the head swollen and sensitive. The game is one of balance, of pushing just a little further, of finding the edge and backing off before tumbling over into sweet release. The cock-ring, a relentless taskmaster, ensures that the struggle is real, the pleasure intense, and the ultimate goal, orgasm, remains elusive, a prize to be won after days of denial and torment.
