To be able to handle a two girl meet. I often find I’m exhausted with one but really want to try out two. Greedy I know.
Not really greedy; it's a service some girls offer and we're hardly likely to be offered it in our private lives, are we?!
I was in a similar position a couple of years ago. I'd had a
really bad MFF early on in my punting days where two young SPs from a Parlour I visited in those days also offered the service when they weren't on the Parlour's rota. Basically they took a foolish middle-aged man's money for an hour of very little activity. So, ever since, a good MFF had been a kind-of, 'must-do before I retire' with me.
May I suggest that you do as I did a couple of years ago: visit your Regional Board; and ask fellow-punters on there for their recommendations of SPs who provide MFF; then see at least one of the girls you choose - preferably, both - individually to see if you get on with them. During your time with her/each of them, explain what your hopes are for your hour with the two of them.
And good luck!
