In the dim light of his room, he teases his pucker with the cold, smooth crystal tip. Slowly, he pushes it deeper, his breath hitching as he feels the plug fill him. He works it in and out, his asshole clenching around the toy, his body responding to the kinky pleasure. He leans back, legs spread, and fucks himself with the plug, his cock hard and leaking, until he can't take it anymore, pulling out the toy and stroking his cock until he cums.
