"Azusa Igarashi, a beautiful girl with an intense desire to lose her virginity despite the pain—repeating 'It hurts (but I want it inside), it hurts (but I want it inside).' Though she's dated over 20 men by age 18, she's never fully taken a penis inside her because the pain was unbearable. Her untouched, delicate breasts remain as pure as the pink hue of her nipples, preserving her virginity until now. As her soft hair is brushed aside, her erotic switch is triggered. She calls her first penetration ritual the 'push-in-and-pull-back breakthrough strategy,' determined to overcome the pain and embrace a new experience."
