I'm staying at my brother's house for a month while I'm job hunting. My brother has a beautiful wife called Hikari, but I'm not very good at socializing and I don't have a girlfriend, so just having such a beautiful woman under the same roof as me made my heart pound. I wanted to touch that body somehow...I wanted to lick it...I wanted to have sex with her. So while my brother was away on a business trip, I decided to secretly give Hikari an aphrodisiac.
