You don't mention required ladies age/type of girl/blonde/busty/otherwise criteria?
Don't use agencies personally but have had encounters with some of the Sugarbabes Int/UK Sugarbabes ladies in other scenarios:
Louise - extremely filthy when I used to see her back in the day, all action, great oral, fucking, A level, CIM etc
Harriet - ditto, no A level but ex porn star, v slutty, massive enhanced tits to spunk all over, talks dirty, toy show etc
Karlie Simon - v horny blonde, big, enhanced tits, great OWO, attractive, fun lady
They all dress to thrill if you're into that.
Depends on what you want, young, under 25 or someone who's experienced/knows how to please as these 3!
Can't comment on other SB ladies or other agencies/ladies listed as I've never used
Good luck!
