ADN-693 I secretly gave my brother's wife, who despises me, an aphrodisiac and impregnated her with my seed. - Kaoru Yasui

Synopsis

I've been staying at my brother's house for a month while I look for a job. My brother's wife, Kaoru, seems to despise me, but I see her in a sexual way. I want to have sex with her somehow. I keep secretly giving her aphrodisiacs I bought online. As the days go by, it's clear that something is wrong with Kaoru. The aphrodisiac was really effective.
