Here's a reply back from the txt I sent her asking if the £70 was correct.
"Normally is £100 for 1 hr, which includes normal sex, BJ, massage, French kiss, 69"
So it's not £70 after all. Obviously only advertised at £70 to lure people in. I also asked if there were any hidden extra prices to pay, but all she replied back with is that she only does incalls, and works until 22:00.
