The big-assed athlete from the prestigious track and field club gets his asshole developed by the coach and becomes addicted to anal pleasure. During lower body strengthening training, he is tasked by the perverted middle-aged coach to train with a 1cm air chair while straddling an erect dick! Dripping with sweat, legs trembling while trying to keep the wide stance, but unable to endure it any longer and get anal penetrated! The coach's rock-hard dick waiting below thrusts into the asshole, making it spasm to orgasm! Even after cumming multiple times, the non-stop internal ejaculation thrusts drive him into a fall of anal pleasure!
