[MUDR-107] Ma sœur, qui est une monstre du sexe, fréquentera une école de jour à partir du printemps. Avant qu'elle ne déménage, nous avons eu trois jours de sexe sans arrêt dans ma chambre.
On the day my parents leave the house for a memorial service, I find myself alone with my sister, who is about to move out soon. She's always been the pride of the family, smart and cute, but seeing her defenseless figure... I couldn't resist my desires and forced myself on her. Then, she confided that she might have a stronger sexual appetite than others... From that day until she moved out, we had sex repeatedly... This is a record of those days.
