In truth, Asuna is exactly his type—older and well-endowed, she's the perfect woman for him. But Daisuke, inexperienced with women, struggles to close the gap between them, growing increasingly frustrated. Finally, in a fit of desperation, he resorts to peeping on her in the bath—only to face an unexpected turn of events. Rather than getting angry, Asuna loses her composure and begins seducing him with her massive breasts. In that moment, their feelings unexpectedly collide.
