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

Naoto's innocent question to the impossibly calm man he calls 'onii-san' backfires spectacularly when the teasing older guy decides to show him exactly what 'eroticism' really means. Overwhelmed by a warm mouth wrapping around his dick and skilled hands working him open, Naoto's protests of 'don't say that to me!' dissolve into breathless cries of 'right there!' as the confident seducer takes him in heated anal intercourse. This first of seven chapters thrives on the delicious tension between Naoto's flustered innocence and his onii-san's unhurried, experienced touch.
