姉孕プリンセス

あらすじ

I'm now totally confused... I've suddenly become the king?! Also, the girls I make pregnant will become my wives...? Is it true? But Riko, a daughter of the previous king, and Viola, a princess of the neighboring country, actively approach me... As a matter of fact, I'm in love with Yoko. I'll have to make Yoko pregnant while I escape their approaches. Any good ideas...? If Yoko gives birth to a boy, and Riko and Viola give birth to a girl, everything will be ok.... Yoko doesn't know the details, so she might refuse to have sex with me...
