What is squashing ?
I mean it sounds obvious but is it just holding down ?
I’ve seen a lot of subs over the years, and done everything on your list (well not sure what squashing is), unfortunately I’m mostly into the mind fuck stuff rather than the physicality, so I do slap, choke spank etc, but it’s never particularly hard, as I’m to busy calling the girl names and controlling her orgasm and toilet usage.
I will suggest a couple of girls, I have seen this year, but just be completely honest in your contact explain what you want cos I can’t remember who does what exactly. By the way these are mostly outcall
Baby Carrie (really embraces the sub dynamic, orgasms easily with spanking and dirty talk)
Erotic Emms (great all round sub who will rim you until your eyes water)
Little kinky miss (although I’ve been told she has stopped offering sub services, if squashing is grabbing an ample feminine body this girl is perfect)
These are just ones I’ve seen this year, look through my reviews for previous years and see if any are still working.
Sorry on phone tricky to do links, just look at my recent reviews.
