The man's cock, a thick, veiny beast, is adorned with a tight, shining cock ring, accentuating its size and stiffness. His strokes are slow, methodical, each one sending a jolt of pleasure through his body. He leans back, eyes closed, lost in the sensation of his oily skin sliding against his engorged flesh. His moans grow louder, more insistent, as he fights to hold back his orgasm. But the pleasure is too intense, and with a final, guttural groan, he lets go, his cock pulsing as he cums, his body shaking with the force of his release.
