Don't do it! The more you're told not to do it, the more you want to try it. In this case, it's "blow job and real sex". However, the weak-willed beautiful masseuses get excited when they see the customers' rock-hard dicks, and before they know it, they're sucking the dicks with their pure mouths. In the end, they even have sex... The fact that it's forbidden seems to make them even more excited.
