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 saw my male friend getting excited and turned on when he saw girls' panties. Could this mean that my brother will get excited and go crazy too? One day, I flashed my panties to him... and won in seconds. "Sakika... Don't underestimate your brother... Hide your panties..." lol There's no way I'd hide them lol Every time I showed him my panties, he attacked me and screwed me. Big brother, that's so uncool lol But! Forbidden brother-sister sex might be possible!
