I lead you into the barn and truss you to the milking stand. Your heavy udders hanging down as you are tied on all fours with your legs spread wide. I would attach the electric milking pumps and gently finger you to orgasm. Then as you enjoy the glow while letting down your milk, I would lead in my large dog and watch you panic and pull at your bonds as he starts to sniff and lick your wet cunt.
The pumps stretching your nipples into the tubes and his hot tongue slipping over your ass and labia and darting deeply inside you. You cum from the fear and the hot K-9 lounge in your cunt. He jumps up on your back seeking your dripping sex with his large pointed red cock. I help him find your hole and he shoves his cock deep inside you in one push.
Your moans of shock, pleasure and pain make me so hard I am throbbing. He fucks you hard and fast and you feel him continuing to swell inside you. You feel his knot pushing against your labia with each thrust. He thrust harder and you scream as his knot stretches you and pushes inside you. You can actually feel the hot dog sperm squirting inside you. You begin to buck and thrash as the long orgasm rockets to another level of intensity when his knot swells and presses hard on your g-spot.
You are panting so hard you may pass out. I wet the fat butt plug with the dog sperm leaking from your knotted cunt and push it into your ass. You look so hot! Your breathing is so heavy, and your drooling. You are literally leaking from every hole, tits included. I pull your head up by the hair and force my cock into your mouth. I explode instantly. My cock throbbing, fucking your face, pumping my cum down your throat, as I enjoy what I am watching. I can feel you shaking from the waves of painful pleasure. After a time his knot goes down and he pulls from you with a ‘plop' sound. I hold a wine glass to your cunt and catch a half a glass of dog sperm as it leaks from your hole. Releasing the suction from your tits and untying you I give you your dog cum to drink as I finish draining the milk from each tit with my mouth. You watch as the dog happily drinks a bowl of your milk while you sip and savor his cum.
