You become their pony boy

You feel them clip something cold to each side of your gag and throw something large and heavy onto your back. You try to look around but the gag in your mouth is jerked another way and you see Elsie holding a set of reins that's now connected to your gag. Someone else, presumably Amber, is attaching some sort of belt to your chest and waist.

"Ah...such a cute pony boy!" Coos Morgan who's still watching. "Amber you're a natural at securing that" Elsie adds as you feel the belts tighten on you.

"Thanks, my mom showed me how to do it. Said they were necessary skills for a college girl." and you hear the girls laugh a little.

"Amber, you get the honors of the first ride!" Morgan instructs.

You feel Amber's slight frame slide on to what you now assume to be a saddle of some kind. She takes the reins from Elsie and places her heels onto your thighs gently kicking them. Seeing no other option you start to move forward. Amber gently guides you around the room in a few loops and figure eights. She starts to head towards the door and says "Maybe we should go outside and explore the hall?"

You flush with embarrasment at the thought and try to turn away from the door but Amber jerks the reigns back towards the door and digs her heels in. "ah come on, just a quick ride outside?!"

She leads you all the way to the closed door and reaches for the handle...before sliding off next to you laughing.

"Oh my....ga....sh, you were...actually go to let me....oh...you are going to be so much fun!"

Elsie chimes in laughing as well "can you imagine that prude RA if she caught us in the hall?!"

"Good point! Maybe we should, could be thrilling!" and the girls all laugh again.

"All right freshies" Morgan interjects "time to switch."

With a little "Ah" Amber hands the reigns over to Elsie who hops on. The weight difference is negligible, but Elsie was rougher. Where Amber's had been been gentle and somehow kind, Elsie's were rough, frequently jerking you side to side or back suddenly to stop, giggling almost every time. In essence, she was treating you like a bucking bronco regardless as to your behavior.

"Ok girls" Morgan says "that's enough footage for the initiation. Not to mention ****"

Footage? Oh no, she must have filmed it all.

You feel Elsie dutifully slide off and Amber removes the saddle. You didn't realize how tired you were before now, but your arms and back and aching. Not to mention the bruised on your thighs from Elsie's repeated sharp kicks. They guide you to Amber's bed where you collapse exhausted.

"That's it for me! I need to head out, I'll see you all tomorrow" Morgan says "take care of your toy for the night!" she adds with a wink and then leaves the room.

"He was such a good pony" Amber says "I think he deserves a reward!"

"Hmm...I don't know. I thought he was kind of stubborn" Elsie replied "I think we should punish him."
