[Senpenbankashiki (DATE)] Medicine to Become Another Person 1.2, 2.2, 3.2, 3.4 [Learn JP with H]

A mysterious bottle of medicine lets whoever drinks it slip into another person's skin, dropping its owner into a classmate's chilling confession about stolen pool-class panties—and into the sweat-slicked body of Akane Makino herself, heart racing as unfamiliar sensations take over in the empty locker room. Woven between those chapters, a big-breasted older sister's fixation on little sister Yukari spirals from secret peep photos and borrowed panties to a chloroform rag bought for the night she finally stops holding back. Possession, guilty masturbation, and desire that keeps finding new bodies to haunt make every swap riskier than the last.
