Gishi Saimin
義姉サイミン
A young man lives under the same roof as his beautiful older stepsister, constantly tormented by his forbidden desires for her. Unable to control his growing obsession, he stumbles upon a mysterious hypnosis app on his phone that promises to make anyone obey his commands. Seeing this as his only chance to fulfill his darkest fantasies, he decides to test the app on her, unsure if it will actually work.
To his surprise, the hypnosis takes effect immediately, and his stepsister begins to lose her inhibitions under his influence. As he pushes the boundaries further, their relationship transforms into something twisted and carnal, with her becoming a willing participant in his every whim. But as the line between reality and manipulation blurs, he must confront the consequences of using such power over someone he claims to care about.
