Did an overnight for around £400 but I was a regular so I suppose it was sort of mates rates. We agreed 12 hours but it was more like 15...........................
She arrived around 18.00, we had a quick chat then went up to bed for a few hours of making love. I'd ordered a take-a-away so we had our food and a few drinks. Back upstairs for a few hours then we sat cuddled up watching films.....................think we headed up to bed around 2am, made love then snuggled up and fell asleep.
I woke up around 7am and was conscious that she'd be leaving so brought her coffee and toast to bed, she woke up and gave me a blow job then showered and gave me a big hug before leaving. It was around 9am when she left so as I say around 15 hours together.
The whole experience was pretty amazing but I think it helped that I'd seen her around a dozen times beforehand, I did plan to repeat it but shortly after met someone and ended up in a long term relationship.
My advice is go for it, but choose the girl carefully and if you can book her before if just for a few hours, it's a long time to spend together and you do have to plan things, like how much sex and when you're both going to get some sleep...................
Good luck !!!
