[Hairu Nukemichi (Siina Yuuki)] Boku Swap Ane ~Akogare no Onee-chan to Karada o Irekaerareteshimatta Boku [Full Color]

A studious boy who idolizes his doting older sister gets far more than he bargained for when a body swap leaves him inhabiting her voluptuous form, and her bold blonde friend wastes no time introducing him to pleasures only a woman's body can feel. The game turns when the sister reclaims control, pinning her brother down and declaring his memories and body hers with a merciless titjob he cannot resist. By the final page, selfie sticks and tangled threesomes give way to an even bolder promise: next time they will drag the sullen second sister into the swap and see if she gets dyed too.
