Little Sister's Careless Panty Flash Seduction: Tsundere Hikaru - Hikaru Minazuki

My little sister brought her boyfriend home, telling me "You absolutely can't peek in our room," yet she secretly meets with him anyway. Fully aware of my presence as her older brother, she deliberately provokes me by licking her boyfriend's cock. He ends up ejaculating immediately, leaving her visibly frustrated and unsatisfied. Later, when we're alone at home together, I try to focus on playing video games, but I can't help noticing her accidental panty shots—soon, I'm fully erect. Noticing my arousal, she mocks me at first, but when she spreads her legs, she becomes excited herself, and our relationship takes a deeper, more sexual turn. Unable to control our desires, I insert a vibrator into her, causing her to start pissing. I make her take my cock deep into her throat, crossing the final line. As my cock penetrates my little sister's slit, she becomes so aroused that she can't stop peeing again.
