[Hinotsuki Neko] Tell Me! Mating Teacher! ~Teaching Making Babies with Your Body~ (COMIC Grape Vol. 104) [Insomnum] [Decensored]

Ms. Takamine expects an ordinary school day until Mr. Yoshida commandeers her homeroom for a hands-on lesson in baby-making, with the flustered teacher pressed into service as his living visual aid. Coached through stroking him, foreplay, and a full 'impregnation' demonstration before her wide-eyed students, she fights to keep her composure even as her trembling body betrays how thoroughly the lesson lands. What begins as coercion curdles into eager commitment as she vows to keep demonstrating non-stop until she becomes a mother herself.
