[Ringo no Naru Ki (Kise Itsuki)] I Wish I Had Not Known [DevilDongTL]

A collared schoolgirl offers herself to an older man, insisting she can satisfy him better than her classmate ever could. Bound in cuffs and dragged along his leash, she endures fingers and toys until the hurt melts into helpless, squirting pleasure she can no longer pretend to resist. And just when she thinks he's shown her everything, he teases that even more mind-breaking things are waiting out there.
