[Hayake] Hentai Ani ni Goyoujin (Nani Suru no!? Onii-chan!!)

A brother's open appreciation for 'little sister' erotica gets him caught red-handed by the real thing—his elementary school sister Shiori, who punishes his perversion with a swift kick before he pins her down and forces himself into her impossibly tight heat. Her protests dissolve into overwhelmed, cock-drunk gasps as he pounds her into the mattress and finishes deep inside, leaving her dazed and twitching while he checks if she's okay. The real payoff comes after round two, when Shiori reveals she's confiscated every one of his porn magazines—because from now on, if onii-chan needs release, she's the only outlet he gets.
