Karate instructors stripped down and fucked like animals after class

Empty dojo, mats still warm, only the ceiling lights humming. The two ripped senseis (one tall, one stocky) lock the door, bows turn into hungry kisses. Gis drop to the floor, belts used as cuffs. She pins him against the mirror, drops to her knees and swallows his thick cock while he groans. He flips her, bends her over the heavy bag, spreads her legs and slams in raw from behind (every thrust echoing off the walls, her palms slapping the mirror). They switch: she rides him on the mat, hips grinding hard, sweat flying, both still wearing their black belts around their necks. Final minutes he lifts her against the wall, legs wrapped tight, pounding until she screams and cums. He pulls out and blasts thick ropes across her abs and tits while they both collapse laughing and panting on the dojo floor.
