Hanayome Shuryou ~Zettai Kairaku no Hakudaku Indoku~

The protagonist is the heir to a prestigious family with a 1,000-year history. Despite being a boy, he is given special treatment at the family's prestigious boarding school for girls. Perhaps due to the influence of the imperial studies he was taught from a young age, he has a strong desire to dominate and possess, and a sexual preference for fellatio, which satisfies this desire. He also has a unique constitution, in which his semen has an aphrodisiac effect. As a side effect, he has been forced to ejaculate daily since adolescence. One day, upon the death of his father, the head of the family, he became the heir to the family. Since one of the conditions for inheriting the family estate is marriage or engagement, he is forced to quickly find a spouse. The protagonist immediately selects three suitable candidates from the school he attends as his bride, and using the aphrodisiac properties of his semen and the power of his family as his weapon, he takes action using all means at his disposal.
