Not sure of your preferences regarding the service provider (age, physique etc) whether your looking for parlour or indy, with a dungeon or domestic setting etc as well as area or distance your willing to travel
A good Dom in a domestic setting is Mistress Kinxx who specialises in pegging. I dont know if shes currently working with the covid situation External Link/Members Only or External Link/Members Only
In a parlour setting Mistress Martine at Roses Retreat could be worth a visit. Ive not seen her for pegging but had a really enjoyable dom session with her External Link/Members Only
Yes, this is very important information to be able to help.
There are quite a few dungeon options, but I would highly recomend Mistress Martine at Roses. She absolutely blows my mind with her domme service, and is superb at pegging. You almost feel like the strapon is a real cock permanently attached, due to the skill with which she uses it. Let them know in advance so she brings stuff in with her.
Also Libby and Amber there.
Christine, Scarlet, and possibly some others at Sheridans - ask Nicola for advice.
Milly, McKenzie, Harriet at La Maison (thanks for the tip on Lara).
SallyWhore and the blonde reception lady (Cheryl?) at indigonile
On the dungeon side there are many Mistresses:
Miss Kitty
Mera already mentioned, lovely lovely girl
Teressa
Sheba
Rhianne
The Countessa
Pamela Isley
Victoria
Dahlia
Nyx
Brown
Eliza Lou (Halifax)
Kristina (Huddersfield)
Good question to ask, even if some feel you're leeching.
I worry how many decent posters we lose here by jumping down their throats too easily - it's at least provided a useful thread.
