[Kumano Tooru] The More We Fight... (Kenka suru hodo)

Dan Toshirou is the strongest fighter in the belt, feared by every delinquent around, yet he refuses to throw a single punch at his persistent challenger Sajima—driving the scrappy tomboy to a furious breakdown over being denied a real fight. When her provoking finally pushes him too far, Dan tears her uniform open to expose the soft, full breasts she's been hiding beneath her crossdressed bravado, and their rivalry ignites into something far more physical. What follows is a rough, muscle-on-tomboy coupling where Sajima discovers she loves being overpowered by the man she wanted to beat, gasping for harder thrusts even as he lifts her off her feet and finishes deep inside.
