SONE-732 — My Little Sister, Who I Used To Play Wrestling With, Has Been Showing Me Her Panties A Lot Recently. What Will You Do, Big Brother? Go For It!? Saki Shirakami

I'm a little sister who used to lose to my brother in pretend wrestling games until recently. I've never won anything against him. It's frustrating... So frustrating... But! Recently, I witnessed my male friend getting excited and horny at the sight of girls' panties. Could this mean that my brother will get excited and go crazy too? One day, I flashed my panties to him... and I won in seconds. "Sakika... Don't underestimate your brother... Hide your panties..." lol There's no way I'm going to hide them lol Every time I show him my panties, he attacks me and screws me. Big brother, you're so uncool lol but! Forbidden brother-sister sex might be possible! *Warning: Sakika's panties digging into her meaty butt and her white skin peeking out from her panties are too erotic*
