[Mizuyuki] "Someday, Again" (Amami)

Tojo and Tegawa have turned studying into the sweetest kind of bribery — every good grade earns time in bed, where her huge breasts heave and her voice leaks on its own before she can stop it. Playful teasing over prepping her ass for anal as the 'next reward' gives way to breathless, sweat-drenched lovemaking between two sweethearts who already know each other's bodies by heart. By the final page they're tangled together in the sheets, trading promises of maid outfits for good results and attending the same school, proving the real reward was never the grades at all.
