Aah, mine was cracking on for 15 years ago at the ripe old age of 25, where the relatively new technological marvel (at the time) that is the Internet led me to a review site and, from there, towards an SP a couple of towns away. My choice was made for three main reasons - she reviewed well, she offered 15 minute bookings and I could get there, back and dispense with the deed in my lunch hour, whilst still having time for some actual lunch.
I already knew she was 20 years my senior and the only thing that caught me off-guard was that she looked to be a frequent visitor to the sun-bed salon. In reality, I later found out that she went abroad quite a lot and was a bit of a sun-worshipper.
The experience was divine and my fifteen minutes was a whirlwind of selfish indulgance - exquisite kissing and some oral that left me in a bit of a tizz. The age difference was something of a turn-on and the fact that she was also rather attractive, had an amazing figure and was just a lovely person didn't hurt either.
I clearly did quite well for my first time in comparison to some and had the pleasure of visiting said SP frequently for the next ten years. Happy days!
