Hitozuma Heaven 2 -Hanshoku Mansion Hitozuma no Shikyuu o Kodane de Mitasu | 人妻天国2 ～繁殖マンション、人妻の子宮を子種で満たす～

The protagonist, Daisuke Fugou, acquired a vast amount of money through foreign exchange trading during his university days. With that money, he invested in real estate and stocks and became a wealthy man at a young age.

Using his immense wealth as a weapon, he acquired whatever he desired and had as many women as he wanted, but there was nothing that money couldn't buy, and he soon grew tired of it. Daisuke, who had grown tired of life because of his enormous wealth, became interested in things that money could not easily buy, such as women who were in love with other men and married women.

As Daisuke did not need to work because of his wealth and was not bound by time, he built an apartment building in the suburbs solely for the purpose of seducing married women. He lived in the apartment as the owner and began scouting for target married women.

Unable to find a women to his liking, Daisuke was getting desperate when a couple moved into his hunting ground, a mansion. Drawn to the beautiful and perfect-looking wife, Kaori Terauchi, Daisuke targeted her and got closer to her as the owner and a resident of the same mansion. With his skillful words, he found out about her worries and learned that she wanted a child but was being denied pregnancy by her husband. Timing it so that he could catch her when her husband was out working, Daisuke succeeded in exploiting the gap in her heart that longed for a child and had a physical relationship with her. Daisuke was greatly satisfied by the days of taking advantage of Kaori's weakness, having a relationship with her, but some time after he had charmed Kaori, another couple moved into his hunting ground, the mansion.

The new wife's name is Misao Yazaki. Daisuke was attracted to her mature body as she had 10 years of experience as a housewife, and he approached Misao in the same way as he did Kaoru and gained her trust. He then learned that Misao was struggling with infertility. Daisuke learns that Mimori wants to be impregnate just like Kasumi and without hesitation he plans to impregnate Mimori with his own child. He succeeds in entering into a physical relationship with Mimori, who is suffering from infertility and sexlessness.

Kaori and Mimori both recognized that continuing their physical relationship with the protagonist was a betrayal of their husbands, but they continued to have physical relationships with him because of the pleasure that Daisuke gave them. Kaori and Mimori... Daisuke repeatedly planted his seed in these beautiful women's bodies, making effective use of the times when their husbands were not around.

Kaoru Terauchi is a newlywed who has been married for only half a year. Mimori Yazaki is a mature housewife who has not been blessed with children.

As the two housewives experience Daisuke's vigorous sex, which is much more virile and powerful than their husbands, they gradually succumb to the pleasure and come to accept Daisuke's seed-planting with joy.
