“What is this?” Ivy asked. My long and curly haired dark chocolate roommate was referring to the small black and red pile of leather and chain lying on my bed. She had asked quite innocently when she first came in, picking up soda cans and trash around the room. Then she looked at it with novelty when my face went beat red and I couldn’t answer right away. Now she was standing over me, hands on her hips waiting for an explanation.

“It’s---nothing.” I mumbled, looking away from her questioning eyes and pearly smile.

“Nothing huh? Looks like something.” Coyly she lifted the leather and let it hang in her hands. By the way she analyzed the leather and chain she clearly had no idea what it was. It was a piece of adult equipment that I’d rather she hadn’t seen, that much she knew.

She turned to me. “Come on Penny. All of us girls have our dirty little secrets. You tell me yours and I’ll tell you mine.”

“It’s---well---“ I torn between talking my way out of the situation and coming clean. Ivy was my roommate and a friend I could trust. Plus I was no good at lying and she was no good at letting things go. But my dirty little secret as she put it was so embarrassing. Could I really tell her about my guilty pleasure?

“It’s a ponygirl harness.” My stomach tied into knots like never before. The embarrassment would not end I realized as my roommate looked at me with a puzzled expression. I would have to explain. “You---well---I wear it.”

“Oh---OH, I see now.” Ivy exclaimed, seeing the harness in a new light.

“Actually, you have it upside down. Here.” I flipped the harness over and turned it around before hanging the heavy shoulder straps in her hands.

“Isn’t this how I had it? Ugh---I guess I don’t see. Put it on and show me.”

“What? Oh, no. I couldn’t.”

“Oh, come on. Well, whatever. You don’t mind if I try it on do you?” Ivy held the harness up to her and gazed at herself in the mirror.

“It---um---won’t fit.” I said honestly. I had bought it custom to fit me with little slack. Since Ivy was noticeably taller than me her shoulders and more significantly her private area would be very uncomfortable if she could get in it at all.

Ivy didn’t know this and took it as an insult to her figure. Her gorgeous body would make any man look twice and then probably run into something but for reasons beyond me she was incredibly self conscious about her weight. I knew I wouldn’t be able to explain what I meant without making the situation worse.

Still I had to try. “It won’t fit vertically. You’re taller than me. That’s all. I didn’t mean---anything else.”

“Sure. I’m fat vertically. I understand.” She scowled.

“Okay, fine. I’ll put it on and show you.” Driven by guilt I took the harness from her and set to putting it on over my clothes. It wasn’t as easy as I had thought.

Normally, when I was safely behind locked doors I would strip down and let the smooth leather glide across my bare skin with ease. I had never tried it over jeans and a T-shirt before and it was proving to be quite impossible.

“You know what you have to do.” Ivy said with a cheeky smile. I stared at her. Surely she didn’t expect me to expose myself in front of her. She pulled up a seat and made herself comfortable, leaving no doubt. With a sigh I headed to the bathroom but was stopped short. I looked back to see Ivy on her feet, her hand firm around my shirt tail.

“I don’t think so. You go in there and you’ll never come out.” She was probably right but so domineering. I thought about telling her off but couldn’t find anything to say. I had insulted her. She had the right to be a bit bossy with me.

So I returned to the center of the room and she in the chair. She had seen me in my underwear before as I had her but having to undress in front of her was a little weird. My shirt and jeans fell to the floor unceremoniously, revealing a very plain black bra and matching panties. I would be able to fit in the harness now no problem, but a subtle and playful shake of Ivy’s head denied me the option.

Taking another deep breath I unhooked my bra and let it fall to the carpet, my small but perky breasts free to the world. “Satisfied?”

With another coy laugh she pointed to my panties.

“Oh come on! This is ridiculous. There is absolutely no reason to take those off.” I remarked, finally showing some backbone.

“No need to get bent out of shape, Penny. I just want to see a---what was it? Ponygirl? If you think ponygirls should wear panties underneath then by all means. Keep them.” Ivy said.

Damn her. No ponygirl would wear panties underneath their harness. Though I was ponygirl in fantasy only, wearing panties in such a fashion did seem wrong. Losing them would mean showing my sex but only for a moment. Then the harness would hide it again.

I lifted the band over hips and let my last article of clothing fall onto the pile. Ivy looked me in the eye and did not stray. Somehow this was more unnerving than if she had looked. At any rate it was time to don the harness and get this over with.

I slipped the first leg through, then the second before pulling the harness up my waist and over my shoulders, with ease. After adjusting myself just a little I was harnessed. My sex was hidden by a simple leather strap that went up my behind. It spared my precious spot but left my ass hanging out and vulnerable. Although my breasts were supported, framed by leather and cold metal links, my nipples were clearly visible.

I looked at Ivy who had left the chair and was circling me, examining the harness in its entirety. She dropped to her knee, her face inches from my pussy. To my surprise she grabbed the harness and gave it a firm tug.

“You’re right. It would never fit on me.” Ivy said finally, “I don’t get it though.”

“What do you mean?”

“Don’t get me wrong. You look hot. Like really hot. But you don’t look much like a pony. What exactly is a ponygirl anyways?”

I paused for a moment, having never really thought about it before.

“Well, they dress up like ponies, prance around, pull carts, stuff like that.” I explained, “They usually have a trainer or something to control them.”

“And you do---have a trainer I mean?” Ivy asked.

“Um---no. I usually play around by myself when no one’s around.”

“Oh, Penny. That is the saddest thing I ever heard.” Ivy rose to her feet and circled around wrapping her arms around me from behind. “A ponygirl without a special someone to guide them, like a lost sheep without a Sheppard. Strayed, disconnected, lonely.”

It was true. Playing ponygirl in my room was wonderfully erotic but ultimately incomplete. A ponygirl was rather useless without someone at the reigns. I had always envisioned a tall, built man taking me from society and making me his beast of burden. Sometimes he forced me, sometimes I came willingly, sometimes I begged him to take me and use me. It was my fantasy.

“Penny, I can’t believe you haven’t asked me yet.” Ivy whispered in my ear.

“Asked you what?”

“What my dark, dirty secret was. You have shown me yours it is only right to show you mine.” I could feel Ivy blow on my neck sensually. “I like to dominate girls and make them mine.”

I heard a subtle and heavy click, deafening in comparison to Ivy’s sweet whispers. She was giggling softly as I stared at the source of the noise, a purple bicycle lock, my bicycle lock, used in a way I had never imagined before. The purple ring ran around a link in my harness just above my belly button before running through the bars at the end of my bed.

“What are you---?” I turned my head to speak only to meet her lips in my first lesbian kiss. I was surprised. Her tongue entered my mouth forcefully but gently at the same time. Caught up in the moment, I returned her kiss. We locked lips for a several minutes, her strong arms keeping mine pinned to my sides. Finally she broke away leaving me linked to the bed and breathing heavily.

Ivy smiled as we returned to earth. Then she strolled over to the pile of clothes and lifted my jeans.

“What are you doing?” My hands were clasping the bike lock as I watched her rummage through my pockets. She finally found what she was looking for, my keys. With a tooth faced grin she held a small purple key up for me to see, the key to my bike lock, my freedom. “Ivy, let me go.”

Ivy frowned before slapping my exposed ass lightly. “Ponies don’t talk. You know better than that.”

Again she wrapped her arms around me from behind locking my arms to my sides. I struggled but she only laughed at my resistance. Her soft hands ran across my skin and stopped at my breast. With a handful of my flesh she pinned my shamefully erect nipple between her fingers, rubbing and pinching until the pleasure overwhelmed me. I stopped struggling and sighed in ecstasy.

“You know, if you really want to be free there is nothing holding you. Just take off the harness and you’re free. What’s the matter? Didn’t think of that? Or maybe you’re enjoying this as much as I am. Maybe you don’t want to be a closet ponygirl anymore. Hmmm---what’s this?”

I looked down at the keys in her hand. The first was easily recognized as my car key, the second was to my bicycle lock, but the third and final key was unmarked. I glanced across the room at the trunk in my closet. Ivy followed my eyes and let me go to investigate.

I gasped, realizing the situation I was in. That trunk held all my remaining pony gear, most of which required a second person and hence had never been used. If I didn’t free myself I would lose the option very soon.

But I hesitated.

Ivy was not a good person. She rummaged through my clothes, took my keys and was about to go through my most personal things. I needed to stop this before my life was in her hands as well.

Fear for my well being welled up inside but I was already consumed with something else, lust. I had never been so aroused in my life, and by a girl. Her words had struck home. I didn’t want to be a closet ponygirl anymore. I was compelled to remain.

The trunk swung. “Wow.” Ivy said with wide eyes. She was probably seeing quite a few things she had never seen before. “You are quite the naughty roommate aren’t you? I can’t believe you hid all this from me.”

Like handling fine silk she lifted the gear and carefully placed it on the bed in front of me. First my bit and bridle complete with blinders, then my pony shoes, then my tail, then my leather cuffs, and last and certainly the most terrifying, my riding crop.

Ivy looked over the equipment laid out before her for some time like she was trying to piece together a difficult puzzle. Then it occurred to me that she probably didn’t know how to use some of it, like the bridle and cuffs. Finally she faced me with the crop firmly in hand.

“So you’re still here. I’m so glad.” She plopped back down in the chair. “Well, suit up and don’t stop until I see a pony.”

She expected me to put the gear on myself to my disappointment. The trainer from my fantasies always put the equipment on me and usually against my wishes.

A sharp pain across my ass jarred me from my vision. Ivy grinned, the crop in her hands primed to strike again. I turned to the bed and picked up the nearest item, the pony tail, jet black to match my raven hair. I screwed it into the back of my harness immediately, pausing only once to rub the mark left by the crop. Ivy didn’t seem to mind, mesmerized by the tail that was quickly becoming part of me.

Once fully inserted, I gave the tail a swirl which she enjoyed wholeheartedly. Another small tap told me not to dawdle. Damn it. She wasn’t giving me time to think. I could only keep going or risk punishment.

The shoes were next, black knee high boots that laced all the way up, a four inch heel without the heel. Bracing myself on the bedpost I slipped the first one on and then the second. Bending over at the waist and giving my roommate even more access to my rear, I set to lacing the boots.

Ivy swatted my ass playfully testing different strokes and giggling joyfully. I took it as motivation to hurry up. I laced the boots to the top quickly and tied them off. At full height I was now several inches taller.

I grabbed the next article, the bit and bridle, fast enough to avoid the crop.

“Not that one Penny. Not yet.” She said firmly.

I replaced the bridle and took the only other item left, the cuffs. Though I consider the cuffs a single item they are really a combination of four leather cuffs and six tiny locks all joining together to create what is in my opinion the ultimate arm binder.

I put the cuffs on one at a time, one on each wrist and one above each elbow, secured with a lock. With the final locks I linked my right wrist to my left elbow and vice versa. When the last click rang I was done and could only stare at the corresponding keys sitting on my nearly empty bed.

At that point I lost it and had a mild panic attack, realizing that I was now stuck. The bed jerked as I fought the bonds holding my arms and the bike lock holding me in place.

I froze suddenly. My fight or flight response was overshadowed yet again by another sensation. Standing on her tip toes to adjust to my new height Ivy was whispering reassuring words of comfort into my ear while stroking my exquisitely aroused sex. I had no idea when she reached her fingers under my harness and into my spot but they were too heavenly to fight.

“It’s okay, Penny. You’re not a closet ponygirl anymore. You’re an owned ponygirl. Congratulations, Penny. You’re mine.” She said, as she worked me with her strong but gentle fingers.

The words seeped in. I understood now why I had to put the gear on myself. She didn’t want to take me. She wanted me to give myself to her. And I had. I had put everything on for her and put myself in her hands. I was hers and the last item would make it official.

At the moment I could scream for help or try to talk my way out of the situation. But once the bit was in place I would lose my voice and be nothing but an animal, her animal.

Satisfied that I was calm and docile, Ivy left my aching sex and began stroking my hair into a ponytail, not a typical ponytail but one positioned much higher on my head. Then with agile fingers she placed the bridle over top. The blinders hampered my vision to what was directly in front of me. This instilled some fear but I remained motionless.

Ivy faced me looking into my nervous but aroused eyes. “Open your mouth.” She ordered.

I opened my mouth wide for her. She pinched my nose shut and kissed me hard and deep. It was the hottest, kinkiest and most romantic kiss I ever had. Finally and at the same time too soon she broke away and let me breathe again. I was still gasping for air when she shoved the bit in deep and let it fall into position.

The bit was coated in rubber but still hard and nasty tasting. Ivy looked over her handy work as I tried to adjust to the foreign object.

“Now you look like a pony.” Ivy said with a smile. I glanced in the mirror and saw myself for the first time. The girl in the mirror was one I could hardly recognize, a fully dressed ponygirl, a girl that couldn’t help but smile from behind her bit. I circled as much as the bike lock would allow and shook my tail.

I looked at Ivy as to say, “What happens now?”

Reading my expression, she smiled but said nothing. She didn’t need to. As Ivy unlocked the bicycle lock and freed me from my tether she could have only been thinking one thing. “What wouldn’t happen?”

When a closet ponygirl meets a wannabe dominatrix the possibilities are endless.
