In the dimly lit, sterile room, a latex-clad figure lies back, his eyes closed, breathing in the cool, sweet air of nitrous oxide. As the N2O takes effect, his balls begin to swell, the skin stretching taut against the inflating testicles. He moans, his cock twitching in its latex sheath, as the pressure builds in his sac. The blue bags of flesh grow, engorged and sensitive, straining against the confines of his latex pants. The soloboy's breath comes in ragged gasps as he edges closer to the point of no return, his balls aching, pulsating, ready to burst.
