Ichika, who is about to get married, is introduced to a man who is an old friend of her fiancé. Ichika, who happened to be left alone with the man, is forced down and has sex with him. The affair that started collapsing doesn't stop, and she ends up enjoying rapid-fire, multi-orgasmic sex while hiding it from her fiancé...

















Honestly, it wasn't quite what I expected. If the title says 'infidelity experiment,' it didn't *need* to be about the boyfriend actually cheating. A simpler story – like suddenly being left alone with the boyfriend's best friend, then getting pressured as the drinks flow, and ultimately giving in – would have been more engaging, I think.
That ripe, erotic body is driving me wild! Everyone loves Seta-san's breasts, and she's such a lewd actress, it's impossible *not* to get hard!
