Lincolnshire for decent escorts reminds of the days when Wales had wet and dry counties. In comparison, Lincolnshire would be dry.
For a university city, Lincoln has a lack of quality service providers, the best I've see was classynewmilf.
Boston has a large Eastern European population, and for a sea port, has a couple of parlours and no one to recommend.
In Grantham, again the quality reported by members is variable, Imogen99 and Serena99 seemingly offering a bait & switch service. Eastwards, theres missfucksalot, but I am turned off by her close-ups with a black cock. Just a personal thing.
The county has it's share of ladies past their sell by date, either in looks or figure. There's bugger all worth mentioning in Stamford, Skegness, Spalding or Louth, so not sure what to suggest, other than asking a lady who does outcalls from Nottinghamshre if she'd mind travelling.
You may be lucky to find someone touring, but again, is it what you want?
I've been visiting customers in the county for 5 years, staying overnight at least once a month, and in that time, I've seen just five escorts - it's that bad.
