"I tried wearing a thong for the first time, and it's super sexy, you know!" My younger sister came to show me her thong crotch and ass! Trembling ass and exposed pussy! I can't take it anymore, let's have sex! Tsubomi Mochizuki

My younger sister, who bought a thong for the first time, got excited by its daring design. Her butt was almost completely exposed, and although she was confused by the sensation of the fabric digging into her crotch, she felt a strange pleasure. Seeing my younger sister like that, I got intensely aroused. Captivated by her thong-clad figure, I groped her ass, savoring its softness and scent. I shifted the thong fabric aside, inserted my erect dick into her pussy, and she began to moan cutely "ahn ahn." Further excited by her voice, I fully savored her slippery, tight pussy. Feeling happy about having sex with my younger sister, I enjoyed the sweet time with her.
