[Chonmage Teikoku (Magekichi)] Childhood Friend Cuckolded by a Middle-aged School Teacher [Black Grimoires]

Ami would give anything for her childhood friend Kou, and their middle-aged teacher Koyama knows it, pinning the petite schoolgirl on his lap and fingering her untouched pussy until she tearfully begs him to take her virginity. When Kou stumbles onto the scene, the older man turns her defloration into a cruel spectacle, ordering the boy to take a closer look as Ami, trembling in her stockings, sobs for him not to watch. Her sacrifice for Kou-chan's sake becomes the teacher's plaything, and her small body is claimed completely while her helpless childhood friend witnesses every thrust.
