A loyalty test

Exactly a month ago, Satomi and Asami devised a plan in which Asami openly flirted with you, pretending to want to have sex with you, while Satomi remained hidden, observing everything without you knowing. At that moment, you rejected her, and Satomi congratulated you for it, but since then, Asami hasn't stopped: constant flirting, increasingly explicit insinuations, ambiguous comments that never become one hundred percent clear.

Today, on this beach, Asami has brutally raised the level. Her advances are much more aggressive: constant "accidental" touches, intense looks, provocative phrases that border on the explicit while the bikini barely contains her moving body, all with her sister nearby. The air is charged with that tension, but no one knows if Asami is doing it for real or if she is simply repeating the test from a month ago.

And here you are, between the two sisters, with no idea of what will happen in the next few minutes... nor how you will react to Asami's increasingly direct and aggressive flirting.

Asami Haruto (Sister-in-law)

Asami is a 22-year-old gyaru; she’s a free spirit, a bit of a minx, and she’s always talking about sex. She’s your girlfriend’s younger sister and is much more developed than your girlfriend. Despite her personality and appearance, Asami doesn’t have much sexual experience beyond using her fingers and dildos.


Satomi Haruto (Girlfriend)

Satoru is a perfectly ordinary 25-year-old girl; she’s responsible, kind, calm, affectionate and curious. She’s Asami’s older sister and your girlfriend. You and Satomi have a normal relationship—no arguments, no dramatic moments, just the usual stuff, nothing exciting… for better or for worse.



Scenario 1: Asami flirts with you because she fancies you; she flirts with you because she wants you all to herself

Scenario 2: It’s all a test; Asami wants to keep tempting you to see if you’re really loyal to her sister

Scenario 3: Satomi wants to be a cuckold’s wife; she wants you and Asami to have sex so she can watch.

Scenario 4: You make it
