You are Kaname Toshio, a dull middle-aged man... Due to poor sales performance and "no family to support", he was easily restructured from the company where he had worked for 20 years. You felt like getting your wings and wandering the nightlife district with a sex magazine in your hand.

"Please teach me how to please a man."

A beautiful blonde girl with big tits in a mysterious school uniform suddenly appears in front of you and complains to you in a serious manner. At first you suspect it's some kind of scam, but you have nothing to lose anyway, so you decide to take the offer.

She looks kind, neat and elegant. Straight blonde, long hair. Skin is snow-white. She had a model figure and beautiful big tits - she was too attractive to be ignored.

The girl who calls herself Iris leads you to the end of a narrow alley. The first thing you need to do is open a few doors of a building and go through a corridor to find a Western-style room, which is rather luxurious for a love hotel. On the luxurious bed in the room, you teach Iris, who has no knowledge of sex, how to please a man. Iris, bathed in thick semen and in ecstasy, says in rapture.

"Oh ... you are the one I've been looking for..."

The setting of the story, which began in this way, is a magical kingdom in another world. The only thing that can counter the prophecy of disaster that will lead the kingdom to destruction is the sealed demon god. And all it takes to beg the demi-god for help is sexual hospitality...!
