The younger brother mistakenly drank an aphrodisiac and raped his sister-in-law

To look for a job, I decided to stay at my brother's house for a month. My brother has a beautiful wife named Hikari, and I don't get along very well with him, I don't even have a girlfriend, so just having such a beautiful person under the same roof is my heart. was arrhythmic. I want to somehow touch that body… I want to lick it… I want to have sex. So, I decided to secretly give Hikari aphrodisiacs while my brother was on a business trip.
