Reunited with My Respected Mentor Who Advised Me to Attend College Through a Delivery Health Service, I Can Only Reach Orgasm by Obediently Having Sex. Igarashi Natsu
"No, sensei... please, not intercourse..." Natsu works at a delivery health service to pay her tuition. One day, she's sent on a job only to find her former teacher waiting for her. She tries to end the session quickly, but when her teacher—using a fake name to bypass the shop's restrictions—whispers, "You don't want your mother to find out, do you?"—he forces himself inside her, making her climax against her will. The man who once taught her now devours her body like any lust-driven older man. Though sleeping with him feels utterly degrading, she can't deny the pleasure she begins to feel.
