In the quiet of his room, the young man's imagination runs wild. He pictures mom, her curves, her scent, her soft moans. His hand wraps around his hard cock, a surge of pleasure coursing through him. He pumps his length, his fantasies growing more intense, more taboo. He can feel his orgasm building, his body tense, his breath ragged. With a final thrust, he cums, his semen spurting out, marking his release, his secret, his solitary sin.
