I have spent a while training my sphincter to take bigger toys but this mistress I saw had one bigger and thicker but I wanted to take the challenge on.
We eventually got down to business, I got on all fours on the bed and she stood behind me. I love a toy with a big bell end and she had one. After a lot of lubing and prepping she teased my bum lips with the bell end, gently pushing her weight against the toy and pulling back out, slowly slowly, each time I could hear lots of slopping and slurping as its stretched my hole bigger and bigger. I could feel my sphincter stretch a bit each time trying to take on this huge bell end. It must be four inches wide this gorgeous head was. I couldnt see what she was doing, she must of had a great view of my bum hole as it tried to take on this mighty member.
She got a nice rhythm going getting that head and thick shaft in there and it wasnt long before the head went through my sphincter and into my rectum.
WOW, I said its gone in and she had to stop as it had locked inside solid. My sphincter had got a right grip on the bell end, like it didnt want to let go. She gently pulled back on it while I arched forward and pushed on my sphincter to try and eject while getting my arms round behind and spreading my ass cheeks as wide as I could.
The head eventually popped out followed by a great sloppy fart. She laughed as that happened, then she used her ring finger to run round my bum lips as I requested her to while I kept my cheeks spread wide.
It was an intense feeling as that head went in, I was hot and sweating but I said go back in again please. She teased me again with that big head and eventually it went in again. We repeated this over and over for a while until eventually she could get that huge head in my rectum then it would come straight back out again with out too much hassle.
She pulled out and I spread my ass cheeks wide, she said gosh I can see straight down inside you, its like a little cavern lol.
I said can I lick the bell end please, and she brought that monster round to my face. The bell end was so smooth and shiny, I said I want to lick it and taste it. The head was too big to get in my mouth, my mouth just wouldnt open wide enough. I licked it all around, got my tongue right under the corona of the huge bell end and licked down the shaft.
It tasted fantastic. I said go on then put in back in please.
