The protagonist, Tomigato Daisuke, acquired a huge amount of money through foreign exchange trading during his university days. He used this money to invest in real estate and stocks, becoming a wealthy man at a young age.
Using his huge wealth as a weapon, he got whatever he wanted and slept with all the women he wanted, but he soon grew tired of it as there was nothing that money couldn't buy.
Daisuke had become bored with life because of his huge wealth, but one day he became very interested in something that money alone couldn't buy… married women who were in love with other men.
Daisuke doesn't need to work because of his wealth and is not bound by time, so he builds an apartment building in the suburbs just to make a move on married women. He lives in the apartment building himself as the owner and begins to look for married women to target.
Just as he is getting frustrated because he can't find anything that suits his taste, a couple moves into the apartment building, his hunting ground. Intensely attracted to the beautiful and ideal married woman, Terauchi Kasumi, Daisuke sets his sights on her, approaching her as both the owner and a resident of the same apartment building.
He skillfully elicits her worries, and learns that she wants a child but her husband refuses to get pregnant. He waits for the daytime, when her husband is away at work, and succeeds in having a physical relationship with her, exploiting the gap in her heart that craves a child.
Daisuke is more than satisfied with his daily lust for Kasumi's body, using her weakness in their relationship as a weapon, but some time after seducing Kasumi, another couple moves into the apartment building that is his hunting ground.
The new married woman's name is Yazaki Mimori. Daisuke is attracted to her, who has been a housewife for 10 years and has a ripe body, just like Kasumi, and he approaches Mimori using the same methods as Kasumi and gains her trust, only to learn that she is suffering from infertility.
When Daisuke finds out that Mimori wants to conceive just as much as Kasumi, he doesn't hesitate to impregnate her and plot to have her conceive his child.
He exploits a gap in Mimori's heart, who is suffering from infertility and a sexless marriage, and succeeds in having a physical relationship with her.
Both Kasumi and Mimori realize that continuing their physical relationship with the protagonist would be a betrayal of their husbands, but they continue to have sex because of the pleasure Daisuke gives them.
Kasumi and Mimori… Daisuke makes good use of the time when their husbands are away to relentlessly impregnate these exquisite females.
Terauchi Kasumi is a newlywed who has been married for only six months.
Yazaki Mimori is a mature, veteran housewife who has not yet been blessed with a child.
With Daisuke's penis far more manly and sturdy than his husband's, and his sex with him full of strength and vitality, the two wives gradually succumb to pleasure and begin to happily accept Daisuke's impregnation.
