Only ever had one MFF, a waste of time to me.
Booked an escort one lunchtime for 30 mins. Turned up at address and she was there with her friend, both good looking and fit. Went upstairs and they said £60 for one for half hour or £100 for both. Only had £60 on me so said only one, the original one I had booked. They had just joined AW and asked if I could take some photos of them on her camera. I was happy to oblige so took some shots of them together.
They then said as a thank you they would both take part in MFF. Anyway, they were like hyena's after a carcase, as soon as I got one off my dick the other was in there, lasted about 5 minutes before I shot my load.
And one of them did not even get her knickers off.
So for me, lesson learnt, prefer one on one, you can then concentrate on what she is doing without paying attention to some one else.
