The brother who doesn't come home until late at night, the sister-in-law waits for him without sleeping. To fill the loneliness, as we talk, we gradually become attracted to each other... I've been holding back all this time so as not to cross that line, but with the sister-in-law's promise of 'just kissing,' we start a life of making out constantly... However, suddenly my brother gets transferred. The sister-in-law and I are separated...! At this point, just kissing isn't enough anymore! I push down the hesitant sister-in-law and go for penetration! Understanding that it's an abyss of adultery, but unable to stop the forbidden sex!
