In the dimly lit room, the solo boy's asshole gapes, a dark, inviting maw. He lubes up his hand, fingers, and wrist, then pushes his hand inside, inch by inch. His body responds, leaking lubrication and farting loudly as his insides protest the intruding fist. He loves the feeling of fullness, the taboo of the act, and the shameful sound of his body releasing gas with each thrust. His balls hang heavy, swinging with each movement, as he brings himself closer to a messy, anal-only orgasm.
