I have just seen a client who had began pushing boundaries at end of booking he paid for 30 mins yet claimed he paid for an hour, he couldn't cum  and asked for money back as I couldn't make him cum, my arms were in acute pain he could see and still demanded pushing me way over time. I just stopped and got dressed.
 He was told to stop as he was demanding I wank him harder and harder and suck him while I wanked him at a speed. I was unable too, my hands and arm were shaking
He then said I tried but wasn't good enough that if he knew it would be that bad he would have got another girl in another area, he tried calling various escorts and got upset when he couldn't get through. I asked him to leave I felt very uncomfortable. He was not violent or abusive just humiliated me verbally 
I gave him excellent oral he said and sex at first ...
