Stay and take it.

You look around at your surroundings, the idea of running crosses your mind, but you have no idea where you'd go and you have no idea how far you could even get in this gear. You hang your head down and let out a sigh.

"That a girl." Sam says as he lightly strokes the side of your face.

Sam soon moves over to the Pony Boy, unhooking the chains connecting him to the cart. You hear loud clopping as he dances behind you.

"Woh boy!" Sam says "Look at how much you're exciting him. He just can't wait to fuck you."

To your surprise, you look down to see you cage shake. Are you getting excited?

Sam pushes lightly on your back guiding your front half down slightly, causing your ass to raise as much as it can in this position.

"I'll have to give our boy here some help getting inside of you, or else your ass would take a pounding of a different kind." Sam says, moving back behind you. Sam takes the Pony Boy's cock in his hand. "My god! He's really been pent up. his balls are so heavy, you're going to be cream filled."

Again, this should terrify you, cause you to want to fight back, but for some reason, you feel yourself assisting as you begin to back up as you feel the guided cock tap your asshole.

"Aw! Looks like he's not the only excited one." Sam says as you feel a hand firmly grope your ass. Sam moves further away, the cock still in hand. That's when you hear the loud smack from Sam spanking the Pony Boy. This is all it takes, Sam's hand pulls away leaving nothing to stop the Pony Boy's cock from slamming inside of you. You grit your teeth as it forces its way completely into you, unsure if your as can even take that kind of stretching. Luckily it does, you feel the Horse Man behind you lean against your back as you feel his balls smacking against your cage. You can't believe that just happened, you also can't believe how good it feels.

He wastes no time, backing up, sliding out of you, only to ram back in. You'd be lying if you said it didn't hurt, but the pleasure you're getting overpowers it. You both moan at in unison as he continues thrusting.

"My god this is hot!" Sam exclaims as he steps back to admire the scene. "Who knew you'd be a perfect breading mare?"

Your mind can't focus on Sam, as it's fully focused on the pounding you're currently experiencing. For its size, you're surprised the Pony Boy's cock is able to slide in and out so quickly, rapidly stretching you again and again. If your cock was free, it would surely be at full mass. Somehow your mate is able to speed up even more, fucking you at full ****. From your experience of being on the other end of this, you can tell it wont be long until the hose of his is spraying. Now you start to worry a bit. If he was as full as Sam said he was, what does that mean for your insides.

You feel him start to shake, knowing he's only moments away.
