Lost in his private world, the man leans back, legs spread wide, and pulls out a gleaming glass bottle from his stash. He teases his tight asshole with a lubed finger, moaning softly as he breaches his own forbidden entrance. With agonizing slowness, he pushes the cold, smooth bottle deep inside, gasping at the intense fullness. He begins to thrust, fucking himself harder and faster, his breathing ragged and desperate. His free hand strokes his throbbing cock in time with the bottle's movements, driving himself closer to the edge. With a final, guttural groan, he explodes, his hot cum spilling over his fist as he continues to fuck himself relentlessly.
