[Sniff Dogs (Ujiie Moku)] My Pupil is a Grade School Anal * Bitch [The Blavatsky Project]

A doting teacher and his young pupil Eri share a secret anal-only arrangement, with the plaid-skirted girl eagerly taking everything he gives—beads, tail plugs, and deep backdoor pounding included. Between breathless gasps and heart-marked moans, Eri confesses how embarrassing it is while her sensei marvels at how amazing her tight grade-schooler rear feels. The story closes with a sweet aftercare scene where Eri, back in her hoodie and skirt, thanks him for the 'medicine' that made her feel much better.
