[Mogiki Hayami] Hugely Crazy Sexy Onii-chan 1-3 [Hergothical]

A sly, boundary-free older brother with a pretty face and an unmistakably creepy streak keeps his younger brother Naoto right where he wants him—pinned down, sweaty, and moaning for him not to stop. Teasing over a mysterious girl from the city spirals into jealousy-fueled confessions, kisses, and anal sessions that claim Naoto's virginity, all while the smirking older sibling coos that his flustered little brother is adorably dumb for caring. Even a casual round of video games with a shy visitor named Makoto can't dull the charge, as every domestic moment bends toward the older brother's next wicked advance.
