I had conversed with Mistress Islya a few times over text and on the phone to plan the session so she had a very good idea of what floated my boat so to speak.

I had locked my cock away in chastity earlier that morning as Mistress had instructed

I arrived at the dungeon and was greeted by the most amazing sight of the beautiful Mistress Islya in thigh length boots and a very sexy outfit, along with a very large strap on cock standing erect from her erotic region.

“you may enter slave” she said with a very wicked grin on her beautiful face.

She directed me to the dungeon and told me to be naked and kneeling on the floor in front of her throne in 5 minutes. I quickly complied and also fitted the cuffs that were left out for me.

Mistress Islya entered the room and ordered me into the sex swing suspended over the bondage bed and restrained my hands above my head and put my feet in the stirrups, gagged me and then picked up a butt plug, lubed it, grinned at me and pushed it into me, laughing as I tried in vane to wriggle away from it until it popped inside me and there it stayed.

“Dont go anywhere slut, i’ll be back soon, or maybe not so soon” and she turned and walked away and out of the room, clicking the door shut as she left.

And so there I was, unable to move or escape, cock locked away in chastity, straining at the bars, my hole plugged by the rather large butt plug, unable to hear much outside of the room as the music played, wriggling in anticipation and discomfort in equal measure.

After what seemed like hours but was probably about 30 minutes i heard her thighboot heels walking across the floor outside the room, i held my breath and turned my head to the door, but the footsteps receded as she walked away again, my heart was pounding in anticipation.

After about another 5 minutes I heard the foot steps again, this time they stopped right out side the door and the door handle moved and Mistress Islya strode in, closed the door behind her and walked to the far side of the dungeon, her figure was mind blowing as she slowly walked away from me. She turned, hands on hips, grinned and said “I hope your ready for this slut” as she poured a little lube onto her cock, her hand wanking it as she slowly walked towards me grinning.

When she reached me she said nothing, simply used one hand to twist and pull the butt plug out of me with a pop and instantly replaced it with her huge black strapon slowly being pushed inside me, a little at a time, all the way in until it was buried inside me. My cock was practically bending the chastity device bars as Mistress started to fuck me, grinning at me as she could see me staring in disbelief at her fantastic huge breasts as they swung back and forth as she rammed her cock into me…………….

The rest of the session I will leave to your imagination, needless to say I am now hooked, obsessed and devoted to my wonderful Mistress Islya
