I think that I'm alone at home, I'm so horny that I decide to try our family dog's knotted cock! I start tasting and sucking the knotty cock, until I notice that you're spying on me from behind the edge of my bed! Although you're my brother, you blackmail me: I have to fuck you and the dog until you both cum, like a good reluctant sister, I accept! I start giving your hard cocks a sloppy blowjob, licking, sucking and doing handjobs, until you both cum at the same time in my mouth, filling it with a lot of cum! You make me ride your cocks, first your big brother's cock and then the dog's knotty cock, making me moan loudly to orgasm, until you both cum in my tight slutty pussy, getting me pregnant! Watch how I humiliate myself for you even more with my dripping pussy full of cum, peeing all over the floor! You turned your sister into a nasty knotty bitch!
