"I might be better than your wife..." A middle-aged salaryman is cornered by a young female employee and sinks. More gentle than my wife... cuter than my wife... she loves me more than my wife... a more erotic woman than my wife... the sexuality of a middle-aged man who has sunk... I want to have sex with "Mai" every day, every night! Many times! As many times as you want! Uncontrollable lust! I'm sinking without brakes now! Should I stay overnight today? "Okay, but I want you to do it many times..." A peerless mistress beauty who makes me sink until I lose my reason, even though I have a wife and children!
