A lone man, Alejandro, delves into the carnal pleasure of solo anal masturbation. He starts by gently teasing his tight asshole, rimming it with his tongue, tasting his own salty sweat. Then, he slips in one finger, then another, pushing deeper until he's stretching himself with four digits. His asshole clenches around his fingers as he pumps in and out, moaning softly. The sound of his wet fingers slapping against his hole fills the room, driving him wild. He's lost in his own world, fucking himself harder, faster, until he can't take it anymore and his cock explodes, spraying thick ropes of cum all over his abs.
