I kept secretly dosing my brother and sister-in-law, who despise me, with an aphrodisiac and seeding their frustrated bodies with love juices. I have been allowed to stay at my brother's house for a month to find a job. My brother's wife Kaoru-san seems to despise me, but I was looking at her with sexual eyes. I want to have sex with Ms. Kaoru somehow. I continued to secretly give Kaoru-san an aphrodisiac that I bought on the Internet. As the days went by, Kaoru-san's behavior became obviously strange. The effect of the aphrodisiac was real.
