[Hotate-chan] Voluptuous Teacher [SaLamiLid]

Nanako-kun's failing grades land him in remedial lessons with Satou-sensei, a deadpan beauty whose enormous chest straining against her blouse makes concentrating impossible. Once class ends, the unflappable teacher flips her switch and takes control—mounting him with relentless cowgirl intensity, milking him between her slick breasts, and ignoring every desperate plea to pull out until he's cumming inside her. Declaring his special extra-curricular training will continue at her house, she rides him until his grades 'somehow' improve.
