This story is real.

I had been a good slave for a long time, but a couple of years ago I discovered my facet as a Master, and since then I've had several pups, two of them more or less regular.

During my time as a slave, I had a Master who used me regularly. Then he got a boyfriend, and we ended our BDSM relationship, although we remained friends and saw each other from time to time to have lunch together.

About a month ago, I had one of my pups tied up in a cross, with the anal hook nice and tight, a gag in his mouth, and clips on his nipples. I whispered in his ear if he wanted to have a session with two Masters at once. I saw his cock getting even harder and he started to drool. He immediately said yes. He tried to say something else, but due to the gag, I couldn’t understand him. I could only see the drool dripping from his mouth.

At the end of the session, I wrote a message to my former Master, proposing if he wanted to have a session with one of my pups.

Since we split up, he hadn’t had any BDSM relationship again, and I thought this proposal might motivate him to want to have a session together again. I wasn't sure if he would accept since he has a good relationship with his boyfriend.

I crossed my fingers. After several hours, he told me he was interested in going back to BDSM. Ufff, what a thrill, I thought.

We arranged to meet on a Tuesday, the three of us, in one of those dungeons that are rented out. But one day before, the pup told me he couldn't come. I told my former Master, but he replied that we would still have the session, but I would take the place of the dog. I remained thoughtful. It had been years since I had been a slave, but going back to being one for my former Master excited me. I obeyed.

At the appointed time, he entered the dungeon. I was already naked and prepared. He told me he had bought me a gift. He took out a gray and black dog mask, one of those neoprene ones with ears and a removable snout. The first thing he did was put it on me, tie me to the cross, secure me tightly with some straps, and start torturing my nipples, my balls, and my cock. I didn't remember how hard it was to be a slave, but my excitement at being with my former Master made me shudder with pleasure.

He started putting clips on my armpits and groin. I didn't remember how painful they were...

He continued playing with the clips, and after a while, he told me he had bought me another little gift. He pulled out a new nipple clamp. When he pressed a plunger, three small hooks came out from the other end. Once placed on my nipple, he released the plunger, and they dug in strongly. I begged him to take them off, but he continued playing, applying them to my nipples, enjoying using the little gift on me.

Then he released me, stuck an anal hook in my ass, and tied me to one of those benches to receive spanks. He gave me a few, and then positioned him...
