Teen Failed Experience With Prostitute

I was an 18 year old 6th form student. We were at a history seminar in London. Near Kings Cross, so the phone boxes all had adverts for prostitutes in them. So I skipped one of the lectures, phoned one of the numbers and turned up at the address having withdrawn some cash. I hadn’t realized the woman ‘specialzed’ in enormous boobs. They were huge, and I didn’t really fancy her much. But I didn’t want to be rude, so I got naked and started kissing her. I was an inexperienced virgin so I asked her to show me where the clit is. She did and for some reason I started licking it. I was really getting off on muffing her. Then I felt her naked foot start massaging my cock as she started to moan and her clit expanded and started to pulse. This sent me over the edge and I ended up coming on her foot. So I left still a virgin, but looking back on it I had a much more unique experience that I still fantasize about.
