I asked an escort i saw fairly regularly about doing a duo with her flatmate who id also seen.
They werent into each other so all the attention was on me which i loved and it was a great Xmas present.
Only problem is the shagging part doesnt really flow like in the movies, to much changing of condoms.
Heard a few comments on here that one girl is more like an extra ehilst the other does all the work..a bit pointless booking a duo.
. It really worked out for me, but id imagine in most cases the fantasy is better than the reality, but something u should experience at least once.
