Yuka is a cute younger sister who spends all day lounging around in her room, doesn't have a job, and is told to do naughty things by her sweaty, stupid older brother. Yuka-chan, who doesn't even like her, and who has a blood relation to her, kisses her on the tongue, puts his dick in her mouth, and thrusts her pussy without using contraceptives, and she has no choice but to orgasm♪
