[Starmine18 (HANABi)] Boku to Onee-san no Kimochii Obenkyou Preview Ban [Tamamo]

A lovestruck classmate dreams of walking to school with Kaede-kun next year, but his real after-hours tutor is a masked onee-san whose enormous bust barely stays contained. She answers his phone mid-session, then bends him over the desk for gloved prostate massage, buzzing toys, and clothed paizuri that leaves the boy a trembling mess beneath her. Femdom teasing and a whiff of netorare promise plenty more feel-good lessons ahead.
