When my drunken sister comes home, her eyes are already blurry from alcohol, but she deliberately spreads her legs in front of me, pretending to be drunk to expose her soaking wet pussy. Her pink labia glistens with juices, and she pants while murmuring, 'Brother, sister is so itchy... come help me scratch it.' She fingers open her slit, juices flowing, tempting me to dive in and lick her plump clit wildly. Sister moans incessantly, her huge breasts swaying, her pussy clamping tightly on my tongue. Finally, she rides my cock, wildly twisting her waist to fuck, her alcohol breath mixing with her screams, squirting her climax all over me, completely becoming brother's exclusive sex toy for release!
