First steps in to mild dom and nipple pain

I never thought this would be me but my interest has been awoken in mild dom
Started punting in March
I am 68 six foot and never had a problem with sex
I started punting and just stayed hard for the full hour
The punts were enjoyable but I just do not come
By chance I came upon mild dom had booked a 3sum and one girl had called in sick so meeting the other girl I mentioned my disappointments
I would hire this girl as a sales person
She asked if in my new circumstances I was interested in things other that blow jobs and fucking
I said yes and she said trust me what else could I say but yes
She left the room and came back with a bag
Ropes out she tied me to the bed (new to me) she put on a blind fold and the nipple clamps
She proceeded to fuck my ass with a dildo and give me a blow job while tugging on the nipple clamp chain
Could not come as anal does nothing for me
But the sensation from the clamps had me thinking
It was a great punt and totally forgot about my first 3 some
I recently had the three some and it was everything I expected but still did not come
In the last 10 minutes I asked one of the girls to bit my nipple
She did and I heard my self saying harder
The other girl joined in and the bit my nipples so hard while one girl rode me cow girl
Had I think the longest shudderingly body wide orgasm ever
So now I am interest to learn about mid dom or at least nipple play
Two days on my nipples are still sore but when I touch them just think of that body wide orgasm
Question
Are there any does and don’t s
What pressure can be applied
For how long can pressure be applied
Would like to hear if anyone else is in to this

Well I'm not into this so I have no advice to offer on the detail, but good luck with it. I hope it continues to work out well. But my first reaction on reading your post was, Christ these women put a helluva lot of work into arranging and satisfying your needs. It doesn't begin to compare with the typical, "Pay up, let's get it over with, and then fuck off" level of service for most ordinary punts nowadays. I may give it a try!

An interesting thread.

In the last few year i had had my peritoneum stroked, its hugely arousing and I have wanted the g/f to go further.

I suspect she would be repulsed! However, if does suggest I am open for some anal play, perhaps even a strap-on

I use Annabella’s and Milton Keynes escorts never had a girl that did not put her all into trying to satisfy me
They also do a loyalty program so every sixth hour is free Those hours are even better
