This sounds like Maria in Yaletown. I recommend her highly. She will give you a tug as part of the $60 if you hint at it and are polite. She's a little shy, but will do it, and will also allow some breast play with her top pulled up and her bra pulled down a little bit -- she won't go fully topless.
A very nice blonde Polish lady, with great massage skills, and I think her shyness adds to the eroticism of the tug. Her apartment is immaculate, BTW.
Search here for her contact info (Maria Yaletown), and please don't PM me, because I won't answer. I've been getting too many mindless pm's lately, seeking info that is either easily searchable or unrelated to anything I wrote.
