in experience stopping can lead to agitation if you request money back..
i had a woman take money agreed dfk, when i tried to kiss her kept moving head away, refused my request to give my £50 back,
no money back even though 100% her fault, even giving attitude, so carried on, real boring, she gave me owo, told me before i cum let her know, so she can get her mouth off..
i said ok, when climax came i did not tell her, cum in her mouth and then all over her face, she hated it, i could not care, she conned me out of money..
got my clothes on and left and told her shit service and never coming back..
