I got there was slightly buzzed (helps me last a bit longer) I had scheduled 2 days ahead. When I showed up the 1st girl came down and gave me head (covered) but when she said "ima have the 2nd girl come down and finish you" I blinked and was like "I thought this was fs" she told me it was 180 for 2 girls bj but I had texts that said fs so I asked instead of arguing about it what the price to have fs with just her would be and she responded an extra 100 so I obliged but I feel scammed and robbed. Is this common? What could have I done different? Just take the semi L and get head from 2 girls?
