Synopsis:

A double-release from Toka Minamoto! The ruthless war between a big sister’s relentless, steamy assaults and a little brother struggling against their forbidden bond begins now!

Yuu is a slightly timid boy with a major soft spot for the "Onee-chan" type. Yurika is a mischievous beauty who happens to have a thing for "Shota younger brother."

Thanks to their parents’ remarriage, these two are officially living together.

You’d think their one-shota interests would align perfectly—but think again! While Yuu is desperately trying to stay a "good boy" and keep his hands off her, Yurika is pulling out all the stops to corrupt him!

From crashing his bath time to playing "sexy tutor" and even "play wrestling"... under such a relentless barrage of steamy attacks, can Yuu possibly hold out without finally losing control!?
