Nariyuki→Papakatsu Girls!! The Animation  

Two teenage girls, Chihiro and Eri, engaged in conversation over burgers after school. As their discussion progressed, Chihiro shifted the subject."Could you please listen to my problems?" she asked Eri. Chihiro disclosed that her sexual relationship with her boyfriend was unsatisfying, prompting Eri to share her own experiences and emphasize the pleasures of sex."Indeed, my last client was quite the prize! I can hardly recall how many times he brought me to orgasm! So, would you be interested in observing us?" Initially hesitant, Chihiro eventually agreed and stated that she would simply watch them.
