Not a fantasy, one that is practical, possible and available.
Many years ago at a flat in Swindon with some very pretty ladies was the first time I saw the "Double Decker" offered and I've just seen it mentioned on another Welsh thread.
Simply it is an hour booking at the hourly rate for the establishment but you get to choose two girls, one for the first 30 minutes who then leaves, you have shower and recovery time before your alternative choice joins you for your second 30 minutes. There is no girl on girl interaction, just two 30 minutes bookings back to back.
I doubt if I could manage the recovery turn around now but if I could I would go for;

I've visited both for seperate sessions but if my body could cope, one after the other would be great fun, I think
Of course you have the difficulty of choosing who goes first
