[Sabashi Renya] Nee-chan to Chome Chome [Decensored]

Yuuma believes his passionate nights with his sister are a secret, but an outdoor tryst with another woman in a floral yukata sets the stage for a revelation neither girl ever intended to keep. When his sister and her rival finally corner him together, they admit they have known about each other all along and want him to say outright that he craves them both without holding back. Cornered between two eager lovers who even helped cover up his 'whole room thing,' Yuuma finds his guilty little harem is only just getting started.
