Koji is a perpetual employee who doesn't get excited. - Today, I won a big win at a horse race and went to a super high class soapland to reward myself, but... my wife's mother showed up there! - ! - "Oh, mother-in-law!?" "Koji-kun!?...Please! Don't tell everyone!" Koji forgets his own situation where he is betraying his wife and is surprised to see the hidden face of his mother-in-law, which he did not know. - but…. - "Hey, you never come to a shop like this...Isn't that the girl you are? If you keep it a secret, I'll give you a great service..." Even though she's the mother of my wife, she has a tremendously voluptuous body that I've been curious about for a while. - When you give in to the temptation and surrender to what you are told... an unprecedented, transcendent technique begins to envelop your whole body! - !
