SW-662 - Tsundere Little Sister's Seduction: 'I want to do it with you!' She strips down and begs for it!

My sister Yui is back home and acting like a total tsundere. Caught her sniffing my underwear and masturbating because she's obsessed with me. When she finally admits she wants me, she doesn't hold back. I couldn't resist—we went straight to the bedroom for a wild night.
