[Rudy Saki] When My Friend Became a Tomboy [Full Color]

When a 'TS virus' that flips people's sexes sweeps the nation, the narrator's childhood best friend Takumi catches it and turns into a brash, sharp-tongued tomboy who still lounges around their shared apartment half-naked like nothing happened. Between towel slips, a mortifying caught-masturbating moment, and weeks of mounting frustration, the two finally tumble into bed—where Takumi gasps through her first time, eagerly tries riding, and confesses she wants to fuck every day. Even after that night she plays it cool around their friend group, only to tug his sleeve, blush furiously beneath a ¥2,000 hotel sign, and snap 'You coming or what!?,' with a beach epilogue where a messy finish across her chest leaves her pouting that he made her bikini dirty.
