My girlfriend Yuka's friend, the active gravure idol "Mia", was also my friend, but we had been attracted to each other for a while. During the three days my girlfriend was away on a trip, the emotions that Mia and I had been holding back were released and we ended up together... A forbidden relationship for three days until my girlfriend returned... I should never have gotten involved... But super busty gravure idols are so attractive... A disgusting video of me losing my mind and devouring her...
