DANDY-484 "I give my sister an aphrodisiac and my boyfriend a sleeping pill!

A brother is so in love with his sister that he wants to have sex with her. When his sister's boyfriend, the object of his jealousy, comes to visit, he tricks them both into giving the boyfriend a sleeping pill and the sister an aphrodisiac. Although the brother makes advances on her in front of her sleeping boyfriend, the sister is reluctant, but the aphrodisiac makes her feel aroused. However, it doesn't end with this one time, and the sister becomes addicted to the immoral acts with her brother, who is seeking her body without her boyfriend finding out, and eventually she even asks for creampies herself...
