Cucked by a dog

Story Script:

NARRATOR: She knelt on the floor, her boyfriend, Mark, forced to watch as their massive dog mounted her from behind, its thick cock sliding deep into her waiting asshole.
ACTOR1: That's it, you dumb mutt... fuck my ass harder than my pathetic boyfriend ever could.
NARRATOR: The dog's thrusts became frantic, its knot swelling and locking inside her as it emptied a huge load of hot dog cum deep into her bowels.
ACTOR2: Please, baby, stop this...
ACTOR1: Shut up, you worthless cuck. Your only purpose is cleanup. Get over here and open your mouth.
NARRATOR: She positioned her ass over his face, and with a strained grunt, she pushed, forcing a wet, gushing fart that expelled the warm, thick canine seed directly into his mouth.
ACTOR1: Swallow every drop, you fucking loser. Now suck his dick clean. Show me you're good for something.
NARRATOR: Trembling, he obeyed, taking the dog’s still-dripping cock into his mouth, tasting the mix of her ass and its cum as she laughed cruelly above him.
