We shared dinner at a fast casual joint downtown. I was acutely aware of being barely dressed in my gym shorts and t-shirt, largely because Eliza and Sukis made a point of touching me seductively at every opportunity. My cock remained at least partially erect at all times which they seemed to view as a celebration of their control over me. I was embarrassed, but somewhat happily complicit in this feeling proud of my status as their slave. It was a conundrum but one I was secretly enjoying.
"That was delicious."
Eliza downed the last sip of her wine and began to rise. Suki popped up excitedly.
"Yay, toy shopping. This is going to be great fun."
I rose to join them, taking care about how I stood, since my cock was pretty hard to conceal, being rock hard and tenting my gym shorts for all to see.
"Looks like Jack is excited about new toys, too, Sukes."
Suki laughed and pointedly brushed her hand against the evidence.
"What sort of toys do you have in mind?"
"I thought we'd let my new friend Domino make suggestions. She was very helpful when I was shopping for my new cock. She really knows the inventory and she's a highly experienced Domme I think."
"Cool, let's go."
Suki drove us a few blocks to the store where we parked and went inside. It was large and modern, with displays of mannequins wearing fetish gear and arrangements of all varieties of equipment for kinky play.
"Hello, Domino."
Eliza greeted a severe, tattooed brunette dressed in black leather vest and tight, torn jeans.
"Eliza, right?"
Eliza nodded.
"I wanted to introduce you to my friend, Suki and our slave, Jack. We've come to do some shopping to outfit our new home."
"Have you had a chance to try out your new share?"
"Yes, this afternoon."
"Were you on the receiving end, slave?"
"Yes, Miss Domino."
"Did you enjoy it?"
"Yes, Ma'am."
"He came quite explosively, I was very pleased."
"Mmm, good boy. You're lucky to have a Mistress who lets you cum, many don't."
"Yes, Ma'am, both my Mistresses are wonderful. I adore them both."
She looked Miss Eliza in the eye.
"What did you have in mind?"
"We don't have much in the way of toys, I thought you might have suggestions."
She pointedly looked at the tent in my gym shorts.
"Have you thought about chastity? At least when you're out in public with him you might want to control that thing."
Eliza and Suki exchanged a look and nodded in unison.
"I think that we both like how ready he always seems to be, but you're probably right about public displays of erection."
The three women shared a smile and gentle scoffs at Suki's wordplay.
"We have a fitting booth in back where we could try out a couple of models and sizes. It's important to get the sizing right."
"Perfect."
"Come."
Domino led us toward the back of the store and through a nondescript door marked "PRIVATE." She gestured toward me.
"May I?"
"Yes."
Miss Eliza gestured permission to me and Miss Domino slipped her hand under the waistband of my shorts to fondle my swelling erection.
"Pull your shorts down and spread your feet, shoulder width."
She leaned over and handled me thoroughly, cupping my balls, stroking my cock, pulling twisting squeezing, totally investigating my genitals. She even tested my urethra, slipping her pinky into the hole.
"How do you use him most? Pegging? Do you let him have penetrative contact? How does he tolerate pain?"
"We both peg him regularly. He has awesome oral skills which we both use daily. We don't really torture him much, although he seems to endure pain well. He's a good fuck, sometimes we'll both ride him at once, one on his face one on his cock."
"How do you punish him?"
"He has rarely required punishment. He's very obedient."
"Very good. Now we came back here to fit him for chastity. Do you want to see a variety or do you have a preference."
"What would you recommend?"
"Well, the first question is do you want it be comfortable for him or does he need it be restrictive and harshly controlling?"
"I'd say comfortable, Suki?"
"Could you show us different types?"
Domino smiled at Suki's implication of cruel possibilities.
"Excellent. I'll bring a selection."
She turned and left the simple room.
Miss Suki grabbed my balls and squeezed firmly.
"I think harsh might be kinda nice, remind him he's a slave, put him in his place, keep that rude cock from poking out and inviting attention from strangers."
Miss Eliza shrugged and smiled.
"The control aspect makes sense. We do want him to feel owned certainly."
She grabbed my cock and squeezed it hard, pulling it down painfully.
"It is, after all our cock."
"Yes, Miss Eliza, it is."
The door opened and Domino entered carrying several different styles of chastity enclosures.
"Okay ladies here's several different types for you to check out."
She showed my Mistresses a cage like brass colored enclosure, a smooth plastic sleeve sort of deal, a chrome curved device, a nasty looking cage with a rod that it seemed was to be inserted in my urethra like a sound, and a nasty bit of business, a ring lined with sharp spikes.
Suki picked up the last one and studied it closely. I didn't like the looks of it and her interest in it scared me a bit.
Domino raised the smooth blue plastic one and held it out.
"I think this should be a good fit. We do have other sizes if you'd prefer a smaller one."
"If we select that model, we want it to suppress erection without causing him undue discomfort."
She noticed Suki admiring the spiked ring.
"That device is called Kali's teeth. It's particularly cruel. If the enclosed cock begins to erect the tiny spikes dig into it inflicting great pain which consequently curtails the completion of the process. This blue one inflicts little or no pain, it merely contains the cock preventing it from becoming fully erect. This cage like one is uncomfortable, inflicting some pain when the erecting cock presses against the bars."
"Which do you recommend?"
"They each have their uses. I would recommend reserving the Kali's teeth for punishment."
"Are these correctly sized for Jack's cock?"
"The teeth will be fine. I think we should try the blue one on though, assuming you are considering either of them."
"Let's try the blue one then."
Domino grabbed my balls and squeezed hard, then slapped the tip of my cock until my erection ebbed, then slipped the blue sleeve over my wilting cock, forcing it down until I was fully contained in the tight passage. It forced my dick down in the position where it customarily resided when flaccid.
She gestured to Eliza and Suki in presentation.
"How does that feel, slave?"
"It's uncomfortable, Miss Eliza."
"But not terrible?"
