[Hashida Mamoru] Imouto 69 Ani (Aimai Kanin) [Yxplore]

Chika comes home late from club activities to find her brother already waiting, and their after-school routine skips the shower entirely—she's going down on him before her uniform is even off. The siblings ease into a familiar 69 before drifting to the bedroom, where Chika sweetly asks for it raw and from the front, ribbon still tied as he spreads her thighs. Their well-practiced lovemaking turns playfully jealous when he teases that 'loving it the most' implies others, ending with the possessive girl riding him bare and declaring his cock belongs to her and her alone.
