Post-shower, the mature man towels off, his body still damp and glistening. His gaze falls on his favorite adult toy, a replica of a full, plump mouth, complete with realistic teeth. He smirks, his cock twitching in response. Settling into his armchair, he lubes up the toy and his cock, then presses the mouth against his eager flesh. He gasps as the teeth graze him, a sensation that sends waves of pleasure and a hint of pain coursing through him. He strokes himself in time with the toy's suction, his grunts filling the room. His body tenses, and with a final, shuddering thrust, he comes, his cum spilling out, coating the toy and his hand.
