[Hochidonmai (Donburako)] Ore no Coach ni Natte kudasai! {Chin²}

Young soccer player Haruto, wearing his Kouya Fighters number 9 jersey, begs his bespectacled coach to take charge of his training—and the man happily obliges with a very private practice session. Between a beaded anal toy the coach 'picked especially for him' and lessons in nipple training that supposedly build a better footballer, Haruto goes from nervous first-timer to a trembling, red-cheeked mess repeating 'please take care of me.' Once the toys have loosened him up, the coach pins the tiny player down on the floor and pounds him hard from behind, driving Haruto to breathless moans about weak spots being rubbed exactly right. A teasing tale of endurance drills where sweat, blushing, and whimpers count as cardio.
