[Starmine18 (HANABi)] Pleasure Studies with Onee-chan [ArkOfLight]

A masked tutor with enormous, heavy breasts takes her little brother's poor study habits firmly in her gloved hands, declaring she'll reset his discipline by squeezing the bad parts right from the source. Every lesson comes laced with pleasure—edging blowjobs hidden beneath the desk during English drills, counted strokes and paizuri-style teasing that leave the sweating schoolboy a blushing, drained wreck who can barely hold his pencil. And when he performs well, his onee-chan rewards him with five round trips of her looped fingers, promising that as long as he keeps studying, she'll keep milking him without ever letting him go all the way.
