1973.
I saw a card in a newsagent's window near Leicester Square and rang the number. The "receptionist" was a bit curt but told me the address which was in Kensington. When I got there it was an attractive dark haired lady in nice dark blue underwear and stockings probably in her early 30's. She said it was £12 for a "full service" and I handed the money over. There was no kissing but quite a lot of mutual fondling. She started paying me lots of compliments whilst touching my cock like "I hope it doesn't get any bigger" and "if girls knew you had this they would be queuing round the block". All good for the ego, of course, but sadly just her being nice and I bet she said that to all the boys.
Anyway, down to the business in hand. She took off her knickers to reveal her hairy pussy (de rigueur back then). She didn't take her bra off so I asked her to do so. Her tits weren't particularly big but nice and firm I recall. When we got on the bed she played with my cock some more and she then asked me if I wanted some French. Naively and innocently I didn't have a clue what she was talking about so just said "yes please" to go along with the flow. I really just couldn't believe it when she started sucking my cock! Wonderful!
I started to touch her pussy and then licked it. It smelt and tasted nice, was very clean but seemed quite powdery I recall. I presume that's something she put on it to smell nice. I could tell she now wanted to move things along so she put a condom on my cock with her mouth, guided me on top of her and then put my cock in her pussy. After a few minutes in this missionary position I came. Again, wonderful!
She tidied us both up and whilst chatting though she did say that I was very young and that I should be finding myself a girlfriend rather than visit her. I told her that I had one but unfortunately she wouldn't let me fuck her (things were much different back then!) and hence my visit to her. She smiled knowingly, we said our goodbyes and I left with a veritable spring in my step and a smile on my face that lasted for days....
Sorry, this has now seemed to turned into a bit of a very self indulgent belated review.
