Mark had another idea or two of what he wanted to change for Aidan today. While Aidan himself got something to drink in his kitchen, Mark went into Aidan´s bedroom and quickly found Aidan´s masturbation sock hidden under his mattress. It had been the only exception when he made the rest of Aidan´s socks vanish, but now he had a new purpose for it. So, with the sock he went back to the laptop.
Just before Aidan returned from his kitchen, Mark changed the masturbation sock into a collar for Aidan. Before his eyes, the sock got longer and thinner, merging from a hollow cloth sock into a compact leather band. Out of its former opening formed a small buckle to close it, while the very tip turned into the pin to fit in. Along the now leather band formed a couple of small metal spikes on the outside, while between them were about five small rings to connect something. Finally, just opposite of the buckle, around the former heel of the sock, a clasp formed, which remained empty.
“What are you doing there now, Mark? Another idea?” Aidan asked, not sure if he should fear Mark´s ideas right now. As far as he knows, until now Mark hadn´t changed anything, beside making sure he wouldn´t get ill anymore and wasn´t bothered by the temperature as much. But what if Mark´s ideas got worse for him?
“Oh, I just looked for something. But yes, I have another idea for you. Aidan, you will put on this collar here, it should be fitting. Afterwards you won´t be able to take it off again yourself, but it won´t bother you wearing it around your neck.” Mark answered him, holding the open collar towards Aidan.
Aidan looked at Mark a bit annoyed for this. While he took it and put it around his neck, buckling it on the back of his neck, he said: “Mark, you know I´m not your pet or something. So why a collar? And why is it so damp?” Just after buckling it, Aidan got a whiff of something from the collar, wrinkling his face disgusted. “And what is that smell?”
Mark grinned at him, knowing his explanation would make Aidan angrier, but also that it would soon be forgotten as well. “I thought it fitting. And the dampness is completely normal. And the smell is your own cum in the material. After all, it has been your masturbation aid before. That reminds me, Aidan, you will forget how to masturbate like you did with it and won´t try anything like that. The only way to get release that you know off is by sucking yourself and swallowing it completely, and that you won´t do as often, as your bear with being horny rather than anyone seeing you suck yourself.” Then, Mark grinned more evilly.
Aidan looked horrified and disgusted at that, and needed a minute to say something. “You have made this from that old cloth thing I use to masturbate? That´s disgusting to even think about. And why do you want me to be horny all the time?” Seconds later, the whole thing was forgotten by Aidan. He felt his cock tingle a bit, and his balls felt rather full, but he wouldn´t touch any of it right now. Not in front of Mark at least.
Mark grinned still, seeing that Aidan still wrinkled his face from the smell of the cum in his collar. But as he now couldn´t take it off, and found wearing the damp leather normal, he wouldn´t do anything against it. And Mark had made sure that the leather would stay damp and reeked of Aidan´s cum, but only Aidan himself would notice this. As he made the collar, Mark made sure others would see a completely normal collar, with no smell beside leather from it.
