After secretly giving my sexually frustrated sister-in-law aphrodisiacs for a month, she was now gushing for my penis while her love juices flowed freely. (Ninomiya Hikaru, SAME-052)

To find a job, I need to stay at my brother's house for a month. My brother has a beautiful wife named Hikari. Because I'm not very sociable and don't have a girlfriend, just the thought of living under the same roof as such a beautiful person makes my heart race. I want to touch her body... lick her... have sex with her. So when my brother is away on a business trip, I decide to secretly drug Hikari.
