[Sakeitiba (Samon Shiu)] Riyuu wa Fumei daga Ecchi Shite Kureru Kouhai [mysterymeat3]

When a boy works up the nerve to text his underclassman Kurashiki-san a request no sane girl would honor, she simply replies 'wait a sec'—and delivers. Deadpan and utterly unreadable, she tongues his filthy cock clean, strokes him off at school while muttering that he's a pervert whose requests are 'very unique,' and grants every depraved demand he dares to make. The tension between his near-tearful gratitude and her total, emotionless compliance hangs over every after-school encounter, because even he doesn't know why she'll have sex with him.
