[Morris] Looking for a Flat (Kinshin Soukansha no Nichijou) [YxTL]

Miku corners her brother with a sensible pitch—pool their rent for a roomier Tokyo apartment—but her real negotiating tactic is dropping to her knees and demonstrating exactly what cohabitation offers him. What starts as reluctant sibling bargaining dissolves into breathless rounds of oral worship and desperate lovemaking, until a nameplate pairing his name with hers hints the apartment hunt was settled before he ever said yes. Her cheerful confession about being sent to bring him home for the family business leaves him wondering whether he signed a lease or walked straight into his little sister's trap.
