Birthday Celebration Takes A Turn

This is an experience I'll never forget from back when I was still with my girlfriend, Ellie. This took place about a year and a half into our two year relationship, smack dab in the middle of our kinky phase that defined the final year of our being together. At this point, I was caged to (now Mistress) Ellie for about 3 months now, and so desperately horny and submissive that I'd have done anything for my Mistress. She kept me constantly sexually depraved, often uncaging me just to edge me and tease me, or wearing provocative clothing in front of me, or watching TV while playing with my cage with her feet in the evenings. I would often lick her out or worship her feet, and spent many evenings as her footstool. It was a fun relationship defined by dominance and humiliation and I loved every second of it.

My 26th birthday was particularly fun. I'd been told to head over to Mistress Ellie's apartment at 4, and to be wearing panties over the cage. An unusual request but nothing out of the ordinary. I did as I was told, and arrived fashionably early. I knocked and was greeted to Mistress Ellie wearing a brand new black latex mini-dress that I'd never seen before. She looked incredible, tying the look together with black stilettos, pantyhose, and makeup that clearly took her a while to do. I was instantly sent into subspace. I went to walk in but she put a hand out to stop me while i was still in the hallway.

"Is that how you greet your Mistress?"

Still in the hallway but with nobody around, I got down on my knees and put my face to her beautiful toes, which were peeking out of the front of her 6 inch heels. I gently kissed each foot in the hallway, praying nobody would be leaving their apartment at this hour. Thankfully, Mistress Ellie granted me entry and I crawled into her apartment. She shut the door behind me and I got a quick look at her place before averting my gaze back towards the floor. It was immaculately clean (as usual) save a chair out of place and her play box (which he had gotten rather familiar with) beside it.

Mistress Ellie sat on her couch and had a look at me.

"Strip down to your panties, bitch."

I obliged and she had me kneel in front of her. She caressed my ass cheek and gave it a smack. Then she pulled the panty string up my crack, giving me a bit of a wedgie. Then she leaned back, placed her left foot on my back and her right foot in front of my face. When I went to worship her foot, she kicked my face away gently.

"Only when I say, little boy" she cooed.

I waited patiently for instruction, staring at her beautifully pedicures toes inside of the seductive heel.

"You like these? You got them for me today. I saw them and couldn't help myself. Surprise! You got me this dress too. Don't you love it?"

I wasn't shocked that she used my money to buy herself a gift. She'd done it before. At this point in our relationship, I trusted her enough to know she wouldn't abuse my finances and could be trusted as an approved user on my credit card. As long as she was getting things like this, I really had no issues with her using my money.

"You look incredible, Mistress. The dress looks amazing. You know how much I love latex."

"I do indeed, you depraved little bitch. Good boy. You can start kissing my foot."

I got licking and she leaned back to enjoy the worship. After a minute or two, she used her left foot to jab at my cage a little bit, partly inspecting her property and partly getting me even hornier. I was rock hard in the cage and she obviously could tell.

"Go get the big plug out of the toy box. Go to the bathroom, take a shit if you must, and come back out with the plug in your asshole. I'll give you 5 minutes."

I rushed to the box to fetch the butt plug in question. It was indeed large, and girthy, and Mistress Ellie used it occasionally on me, although typically as punishment. I went to the bathroom to find a bottle of lube on the counter (nice of her). I didn't have to poop so I went about placing the plug in straight away. It didn't go in easily but with some pushing I was eventually able to violate my sphincter enough to get it in. In sat snug in my anus, large enough to spread my sphincter and long enough to tickle my prostate when I moved. I hated this plug and Mistress knew it. What did she have in store for me today...

I came out of the bathroom, with my cage, plug, and panties, to find my Mistress still on the couch, fingering herself with her legs spread wide. She beckoned me over, and as I came closer, she grabbed my hair and pushed my face into her pussy. Horny as I was, I ravenously started licking her clit as she had trained me to do over the many months of our relationship. It didn't take her long before she was approaching climax. She wrapped her legs around my head as she orgasmed, moaning loudly as I locked and sacked her clit relentlessly. As she calmed, I slowed down until eventually she pulled my face away.

"Good boy. I've trained you well at that. Hopefully this won't be the only time I come tonight. And who knows, maybe you'll get to join the fun as well."

With that she reached down and took the cage in her hand. She fondled my balls and gently scratched at them with her manicured nails. If I could have gotten any harder, I would have. She inspected the plug in my ass and played with it a bit. She pulled it in and out, slowly fucking me with the plug. It was uncomfortable but I moaned, loving the combination of pleasure and pain that Mistress Ellie was dishing out. She settled the plug back in its place in my asshole, then brought me over to the chair. My hands were tied behind my back, and my legs tied to the legs of the chair, both at my knees and at my feet. Legs spread and arms bound, I was at her mercy with my caged cock exposed.

"Happy birthday, honey. I think you're gonna like tonight."

With that she procured the key to my cage out of her cleavage. She knelt down, bringing her face close to the resin cage, and took the cage in her hand. With the key still out, she played with the caged cock a bit more, even giving it the occasional lick. I was fully in subspace, and began begging for her to let me put of the cage.

"Please Mistress, please let me out. It's been so long. I'm so horny, please please." I pleaded. She laughed seductively and kept playing as I continued to beg.

Eventually, she put the key in the keyhole and turned the lock. She took off the cage, leaving the base ring in place. My cock sprung to attention, rock hard and sticking up. She giggled at the sight. I could have come instantaneously if she had just stroked me even once, but she didn't. She always seemed to have a sense of when I was very close to orgasm.

With my dick rock hard, Mistress Ellie went over to the toy box and sifted through the contents. Eventually she found what she was looking for. It was a dildo gag, with dildos on either side of the gag harness. The smaller of the two sides was for the wearer of the gag, penetrative their mouth, holding them silent, while also giving them the opportunity for a little cock sucking practice. Mistress Ellie enjoyed this toy, and used it often to convert her slave boyfriend into a proper fuck toy. This time, however, she took the larger side of the gag into her pussy herself, fucking herself standing up getting her juices all over the dildo right in front of her helpless slave. She did this a couple times, going in and out with the dildo, before removing the gag from her pussy and bringing it to my mouth. Holding the gag with her hand, she began throat fucking me with the dildo coated with her juices. I would have loved it if she weren't fucking me so vigorously with the dildo. I gagged and drooled, all while she continued fucking my mouth with the business end of the gag. Eventually I could feel tears coming out of my eyes as the gagging continued, Mistress smiling every time my gag reflex went off.

"That's it bitch, take that cock in your mouth. Let it slide down your throat, bitch boy. Mmmmm, good boy."

Eventually the gag reflex calmed down, and she was able to hold the dildo in my mouth, pushing against my throat for longer. After a couple minutes of this, she secured the gag in place around my head, backwards, so the larger side was still affixed in my mouth instead of sticking out. I disliked the dildo permanently filling my whole mouth, but with the dildo secured she once again focused on my dick, still rock hard from the attention I was receiving from my beautiful Mistress. She gently caressed my cock, never stroking but doing everything else to keep my right on the edge of cumming. She continued this for a minute or two, caressing my balls and cock and keeping me aroused for her enjoyment while the dildo tested the patience of my gag reflex. I was on cloud 9.

So much so, that I almost didn't hear it, but a phone vibrated from the corner. Single vibration, so a text. Mistress Ellie got up and checked her phone. I couldn't see her reaction but she came back into view shortly after.

"Oh, you have no idea what's coming little bitch."

With that, she began a bit of a strip tease. The latex dress came off slowly and seductively, revealing a lingerie bra and panty set that I bought for Mistress a few months prior. The latex fell to the floor and she picked it up and draped it over my face. The bit of sweat on the dress, the unique smell of the latex, and the shine that I could feel was captivating. But I couldn't see what was coming next. I was taken in by the sensory overload of the latex on my face so much that I didn't register what my Mistress was doing. All of a sudden, I felt Mistress take my erect cock in her hand and dunk it into a bowl of ice water. It shocked me and I gasped. The bowl of water had the desired effect: I shrank almost instantly, and Mistress Ellie seized the opportunity to place the cage back over my dick. With that, the latex dress came off my head, and I was able to see again. She no longer had my key around her neck where it usually was. Furthermore, I saw a butt plug in Mistress' ass and she started touching up her makeup. What's going on?

"I know you thought tonight was about you, honey, but it's not. It's about me and what I want. I met a guy named Jack at the gym hes agreed to explore some kinks with me that I can't with you. As a birthday gift, I'm gonna let you stay and watch. If you don't want this, too bad. Suck it up, it's happening. Tonight it's about me. If you wanna reconsider this relationship after what you see here tonight, we'll cross that road tomorrow. But don't you ruin this for me, bitch."

With that harrowing warning I was left super confused. What was about to happen? Mistress Ellie laid out all the toys in the toy box on the table then went to the other room, coming back holding a posture collar that I had never seen before. The kind that covers your whole neck and keeps your head facing forward.

"I'm definitely using this on you after today, but tonight, it's for me."

She put on the collar in the mirror, securing it snugly before heading by to the front door and kneeling, legs spread. And arms at her knees in a submissive position. And we both waited, her collared and kneeling, waiting with her head affixed forward, and myself, toed to a chair with a dildo secured all the way into the back of my mouth, plugged and in panties. Mistress Ellie's knees

After a couple minutes, a man walked into the apartment and locked the door behind him. He locked eyes with my Mistress, standing over her, and caressed her lips with his hand. He never once looked at me.

"Well you wasted no time getting straight into it. You do everything I told you?"

"Yes sir. Everythingyou requested is on the table there. I had most of it already. " She responded submissively.

I'd never seen my Mistress like this before, relinquishing control so readily. But I could tell this 'Jack' guy was in complete control.

"Good girl." He ran is hands through Mistress' hair then in a flash he whipped his cock out, which was huge, and held it in front of Mistress Ellie's face. She gawked at the size then eagerly and ravenous took it in her mouth and started sucking. The sound of her choking on the giant cock permeated the air and I couldn't help but be aroused, albeit humiliated, at the scene unfolding in front of me. The shift in power dynamic was sudden, and I found myself at the bottom of the bottom of it all. Caged, sucking on a plastic cock with panties on, I hoped and prayed that Jack wouldn't look at me, but it occurred to me that he must have been informed to my presence by my Mistress. The humiliation was intoxicating.

Jack fucked Ellie's mouth until tears of her own started to come out, ruining the makeup she had worked so hard on. When he was done with her, she looked like a slutty mess. Her lipstick smeared across her face and her mascara streamed down her cheeks. Jack slapped her across the face, spit at her, then slapped her across the other side. Then he shoved his dick back in her mouth and throat fucked her harder than Mistress throat fucked me earlier. I watched intently, and Mistress Ellie shot me the occasional glance, even though her head was fixed forward by the posture collar. I was helplessly sitting there, watching my Mistress, my keyholder, get absolutely manhandled into submission by this new person. And she was loving it.

Jack didn't cum from the face fucking he was giving my Mistress, but eventually he pulled out, slapped his submissive across the face again, and made her stand up. She stood straight, and he ripped the lingerie bra off her body. He then proceeded to do the same thing with the panties. Ripped off, leaving just her pantyhose intact. I was shocked. Jack then walked over to the table to inspect the toys she had laid out for him. He grabbed a segment of rope, then came back to Ellie to bind her hands behind her back. The bond reached up to her elbows, and her arms were tightly bound together in an uncomfortable position. Jack went back to the table and grabbed a leather hood, usually used on me, but tonight got wrapped around Ellie's pretty face. The only holes in the hood were two nose holes and a larger hole where her mouth is. Over the hood went a red ball gag, completing the look. My Mistress was now fully at Jack's mercy, and therefore so was I. My new captor had still yet to acknowledge me in the room, even though I was intently staring, shocked at the events transpiring before my eyes.

Jack cleared some space off the table, then bent my Mistress face down across the table and spread her legs wide. He bound Ellies feet to the legs of the table ensuring her ass and pussy stayed fully exposed as she was bent over. Jack inspected the plug in her ass, pushing and prodding it while she gently moaned through the gag. He spanked her ass, hard, a few times, and we both watched it turn cherry red. Eventually he pulled out the plug, slowly, to maximize her discomfort. The plug popped out leaving her asshole slightly agape. Jack placed the sullied plug on the table and retrieved a set of nipple clamps. He stood Ellie up, feet still bound to the table, fixed the clamps tightly to her nipples, then used a segment of rope to loop the nipple clamps to the other side of the table. As he tightened the slack of the rope, she bent back over the table, until her titties were pointed up towards the table where the rope was affixed.

Bent over the table, ass exposed, Jack stood behind my Mistress, spit into his hand and used the saliva as lube, before shoving all 8 inches of his cock up Mistress Ellie's ass. She gasped at the whole length of cock violating her at once, and instantly started to whimper. She was in pain, and I began to struggle in the chair. Jack didn't relent. He thrust his cock deep into Mistress Ellie's ass, spanking her already red ass and using her bound arms as leverage to get even deeper. Her whimpers turned to moans as she took the cock more readily. A couple minutes went by of Jack pumping his cock into Mistress Ellie's ass and Ellie began to scream through the gag as the whole scene intensified. He grabbed both her arms and pulled her close as he thrust into her ass, cum jutting deep into her anus as he came. He pulled out and walked to the bathroom, leaving Ellie bound, legs quivering and cum dripping out of her ass. She had clearly orgasmed as well, maybe more than once, from that ordeal.

I heard the toilet flush and Jack came back out of the bathroom. He grabbed the same butt plug that was in her before and abruptly shoved it right back up her ass, without lube, blocking all the cum that was in there from escaping. He then proceeded to remove the gag from Mistress' mouth, and loosened the rope on her nipple clamps. Still bound, he stood her up, held a hand around her neck and kissed her deeply. Fully in his subspace at this point, she returned the kiss and he shoved his tongue into her mouth, probing and exploring her dominantly. After passionately kissing for a couple of minutes, Jack replaced the ball gag and left Ellie bound to go get dressed and get ready to leave. He returned to untie her legs, but left her bent over with her arms still tightly bound, hood, gag, and nipple clamps still in place.

With that, he finally turned to me.

"She is quite the fuck. Shame you'll never know, sissy boy. I'm out. Go untie your Mistress. Or don't, and leave her like that." He untied my hands and with that, Jack left without a word of goodbye to Mistress Ellie.
