[Nadadekoko] Beware of Gacha and my Oniichan! (COMIC LO 2020-02)

Suzuka would rather burn her entire allowance on gacha pulls than look up from her phone, but her doting big brother knows exactly how to barter — a ¥20000 gift card earns him the right to grind against her pantied ass and prep her slick little cunny for her very first time. What starts as lazy frottage while she scrolls half-interested escalates into fingering, then her blushing and sweating balls-deep beneath her oniichan as she learns sex is a pleasure two people share. And once the deflowered little schemer realizes her body prints money, she's already angling for her next ultra rare off a walking wallet who may never financially recover.
