You're my brother and you come into my room to show me your new big dog! As soon as I pet him, the dog gets excited and starts humping my leg, rubbing his hard cock on my thigh! He approaches my face with his cock and puts it in my mouth, I'm sucking the dog's cock in front of my brother's eyes! He fucks my face with his knotted cock, making me drooling with rough deepthroats until he cums in my mouth! Tasting the dogs cum turns me on, turning me into a disgusting knotty bitch! I bend over in doggystyle to get mounted by the big dog, I get fucked hard in different positions up to the knot of the cock, moaning loudly and having an intense orgasm! I beg for a creampie inside me, until I feel a big load in my pussy! Your sister got breeded by a dog knotted cock!
