[Ronrinri Ronri] Miyu-chan's Feelings (COMIC LO 2022-07) {Mistvern}

A bespectacled tutor wins over a doting single mother and starts visiting her quiet, soft-spoken daughter Miyu twice a week, but lessons stretch later and later once mom steps out. Miyu's shy curiosity about adult kissing melts into fingering, defloration, and nakadashi, her tiny body squirming through cowgirl while her sensei casually takes a phone call from the mother mid-act. By the final page the guilty tutor and his smallest student have declared themselves a full-on lovey-dovey couple.
