So not clop, its just love... and perhaps some bondage

NP: Why did I even come to you for help.
DaBunK: Because I am the only one that isn’t insane.
NP: That’s hard to believe.
DaBunK: Yeah me too, but tell me. Clop or no clop?
NP: No clop. Do you understand.
DaBunK: I promise nothing.
NP: Okay, maybe a bit of clop.
DaBunK: I didn’t understand, what did you say?
NP: Okay, do as you want. Make it juicy.

DaBunK: FUCK YES! Now where is my NSFW tag?

“Can’t believe that they ran out of regular potion,” I grumbled as we made our way back to the bureau, “Now I’m stuck as a mare in heat. Great what next, a drunk griffin attacking America?”

We were in the main common room but we had decided to go back to our rooms to pack. I troted back behind most of the group as I was still getting over the four legs and the naked all the time thing. It was confusing at first to trot but I had it down really well now.

*thump*

“Owww, my nose.” I whined, as I rubbed my muzzel.

“Its a muzzle Natie, not a nose.” Zach said, pulling me up to my four new limbs.

“Thanks.” I replied as his eyes began to wonder towards my flank, “My eyes are here Zach.”

“Sorry, but its just your such a pretty mare.” He said, blushing and looking deeply into my eyes.

“Thanks but would you quit looking at me like that.”

“Sorry but its... it’s just you’re such a pretty mare.”

“Will you two be quiet I’m trying to think of which dress I can take with me.” Snorted an angry, Strawberry Frosting.

“Sorry... we’ll be quiet.” whimpered Zach, putting his tail between his strong hind legs.

‘Well he is a cute stallion... what am I saying... He is one heck of a stallion, not a single lick of fat in his body and look at those strong hind legs. I bet you he could buck a tree straight out of the ground.’ I thought to myself as images of him flashed across my mind.

“What the hay did I just think?” I whispered to myself as my new mare brain was craving for him. Heck every part of me was craving for him and his sexy body.

So here I was, in my room with Zach helping me pack to go to Equestria. I didn’t have much besides a dress that Frosting had helped me pick out as another mare made several because of her new cutie mark. It was a nice plain dress that complemented my coat. It was pretty and I liked it but I couldn’t decide if I should wear it or just pack it away and wear it when I am in Equestria.

“Zach,” I said turning to him, “Do you think I should wear this dress now or later?”

“Well the dress would cover up your beautiful body, but it would make you look pretty.” He said, slowly approaching me.

“Zach. Why are you looking at me like that?” I said backing up until my rump hit the bed that I fell onto my back with, exploding my nether regions.

“Its just that you’re a pretty mare and you want to get out of heat right.” He said, as he put his strong forelegs on my chest.

“Yeah, but...” I said, biting my lip.

‘He is such a handsome stallion but do I really want to do it with him, I mean he was a man not too long ago and I was a dude too. But then again, he does have that gruff sexy stallion look to him.’ I thought to myself as I began to feel something moist gather around my tail.

“I’ll take that as a yes.” He said as he slowly began to nibble on my chest. Slowly caressing the short yet soft brown fur that I had. I could feel his breath against my skin, it was warm and I could feel more and more of it.

Slowly he began to kiss my chest and moved his head down with each once, until he was kissing right between my legs.

“Are you ready?” He asked, with a smile ten miles wide.

“Please be gentle.” I whimpered, as I looked away.

He slowly began to lick,each one sending shivers throughout my body. He kept on licking until I felt him enter. His tongue was soft yet course and I could feel it inside me, touching the wall. He stopped, why did he stop?

“Why did you stop? I waaaassssz...” I began to ask him as he had raised himself upon me. I spotted his massive member, no way that that would fit inside me.

He just chuckled and then slowly ran the tip against my flank. He was teasing me as he knew I was craving for it. But the wait had stopped, he placed it right against the lips and penetrated me. I could feel the whole length of it throbbing inside of me, rubbing up against the walls and causing me to near on cream myself just of the thoughts of it.

He slowly began to thrust and with each thrust came a whinny of ecstasy and pleasure throughout my body. He presses his lips against mine as he began to slide his tongue down my throat in an effort to silence me. It worked and it made me feel wonderful, I slid my hoof behind his flank and held on tight to him.

I could feel a heat beginning to emanate from my flank. I broke away from the kiss and tried to say but I couldn’t as I cried in pure pleasure.

“Oh god I’m going to cum!” I cried out, as the pressure was so immense, I couldn’t hold myself.

“Sweet Celestia!” I finally cried out as I came which cause him to deposit a heavy load inside of me. I could feel it hitting the back of me with force, it felt amazing. I rode out the ecstasy as long as I could until it subsided. Both my body and mind cried out for more but sadly he slid off of me and lied down next to me placing his strong foreleg over my chest.

I rolled over facing him, I felt his warm breath against my muzzle. I intern placed my foreleg over his back and pulling him close for a hug.

“So I take that you enjoyed it?” He asked, with a smirk across his face.

“That... that was amazing.” I stuttered out,

“Want to try for round two?”

“We can’t, we’re leaving for Equestria soon.” I replied, breaking away from the hug. “But we could try for round two in Equestria.”

“Let me help you pack then.” He said, hopping up in a flash.

“Good now help me with this dress.” I said, dragging my tail against his jaw making sure to wave my flank straight in front of his face.

“Sure thing sexy.” He said, as he picked up the dress and packed it away in a saddle bag that was given to us. I had basic supplies that would help us survive in Equestria, but it didn’t matter that much.

“Okay done lets go!” He stated, as he dragged me to the common area by my tail.

“About time you showed up.” Said Frosting, tapping her hoof against the ground, “The boat is going to leave soon and what took you so long because I heard screams?”

“I tripped over myself and hit my head against the bed.” I blurted out, in an attempt to cover over that I was having sex with Zach.

“Oh well... lets get going because that boat isn’t going to wait forever.” Said Frosting, with a look on her face that gave me the feeling that she knew what we were really doing.

The end
