paul, a curious and horny 18-year-old, indulges in his favorite solo activity - fist fucking. He lubes up his tight hole, pushing his fingers in, one by one, until his entire fist is buried deep inside. He moans in pleasure, his cock rock hard, as he begins to fuck himself with his fist. The sound of his wet, sloppy fisting fills the room, driving him closer to the edge. He adds more lube, increasing the intensity, his body trembling with each thrust. His breath hitches as he feels his orgasm building, and with a final, deep push, he comes undone, his cock exploding all over his hand and stomach.
