ZEX-397 Strong sexual incest with a younger sister who hates her to death! I reversed my position with an aphrodisiac and made me go crazy lol Mikako Abe

Yosuke ends up living with Mikako after his parents remarry. Lustful to live with the opposite sex, he searches for Mikako's underwear, but ends up finding out. Mikako, who is disgusted with Yosuke, rejects him out of physiological disgust. Still, Yosuke can't give up on Mikako and uses the aphrodisiac he bought to make Mikako his object. Even though I don't like it with my mouth, my body feels it...
