Thanks pal , i take it .... u have seen them
Yes, all of them except Penny Pocket. In my experience they provide a top notch service (as illustrated by their reviews). They all seem to be up for rough sex and are submissive however I personally have relatively limited experience regarding such stuff. I'm not sure how much "degradation" they'd be up for.
As long as you make it clear what you're looking for (during comms) and they agree to it then I'm almost certain you'll have a good time. Obviously I can't really comment on Penny Pocket (also note that she's outcall only) but her profile and her reviews on here definitely suggest she's up for almost anything you can throw at her. If you do want to see her make sure you read all her review threads as there's some useful info in there including her verification pic. There's also some links to her social media, they might not work now but I do recall they did make her look a bit mental and I'm sure she did also post whinging/ranting about one of her clients (not outing though).
