Fuck me! Is there such a thing as a 4" dick
Presuambly she is talking flacid or circumference (is that how you spell circumference)
No, she is talking what is technically known as 'crap' :
the stuff that exudes from both ends of certain prostitutes when they want a "do everything" profile and and a "do fuck-all except vanilla" service.
A more extreme variation is (after she has taken five minutes to stash your cash in her high-security toilet tank) is:
"Oh my period's just arrived unexpectedly so it'll have to be just oral. Is that ok?"
If it's not ok, of course, well fuck off back home; minus your cash "for her time", minus the money spent on petrol or taxis.Shoodve gone tae UKP!
