Same hole

It doesn't slow down, the thrusting against your hole only gets harder and faster. Rex thrusting into your throat has become faster and more frantic as he gets closer to cuming. Keeping his large knot outside your muzzle before stopping and holding your head down as streams of cum hit the back of your throat as you're forced to drink it down. Rex soon letting go on your head, letting you pull away and getting a few good breaths.

Butch forces the knot inside your ass before it gets too big, not wanting to break thier new breeding bitch. You can feel it getting larger as you yelp and howl as it stretches and tears inside of your ass. Butch holding on as you try to buck and bite him off of you, having a hard time reaching the smaller dog. The knot firmly stuck inside as you soon feel warmth as his seed start to fill your bowels.

"Ya got her good Butch." Rex says with a barking laugh.

"Next time maybe she'll keep her word on letting me breed her." He smirks "That ass was worth it though."
