In the quiet hours, when she's away, he succumbs to the primal urge. A solitary figure in his room, he sheds his clothing, his cock already swelling with anticipation. He runs a finger along its length, smearing the pre-cum that beads at the tip. His grip tightens, his strokes growing faster, more insistent. His other hand reaches down, cupping his balls, then trailing back to tease his ass. He gasps, his body arching as he brings himself closer to the edge. His strokes become frantic, his breath ragged, until he finally finds his release, his cock pulsing as he coats his abs with his warm, sticky cum.
