Secretly giving her sister-in-law an aphrodisiac

I decided to stay at my brother's house for a month to look for a job. My brother has a beautiful wife named Hikari-san, and I'm not very sociable with people and don't have a girlfriend, so I'm always happy to have such a beautiful person under my roof. home. I want to touch that body somehow… I want to lick… I want to have sex. So, while my brother was on a business trip, I decided to secretly give Hikari an aphrodisiac.
