Getting on your knees

As you walk back to the entrance your pussy is dripping so much juices down your perfectly smooth thighs that you have to keep your legs wide to avoid making a splashing sound with every step. This of course doesn't stop you from turning the vibrating anal beads to the highest setting, the beautician pushed them so far up your ass that you feel your belly vibrate.

The beautician is behind the counter talking to another customer, but from your point of view you can see that she is wearing nothing from the waist down. Once the other customer has left you approach the counter

"I'm terribly sorry, I forgot my wallet in the car, can I go get it?" you say
"That's not allowed, but I think that we can arrange something" she replies
"What do you mean?" you fake innocence
"If you can't pay in cash, since I treated your pussy well it's only fair that you treat my pussy well in return"
"Your wish is my command"
"Then I hope you are comfortable on your knees"

You don't need further encouragement: you get on your knees behind the counter and start licking her pussy passionately, she has a mild taste, vaguely salty. Soon enough your face is half covered in her juices, but you keep working.

As your hands caress her legs and butt you notice that she is wearing a buttplug, this reminds you of the anal beads rumbling in your ass, the vibration has moved them back and one is even slipping out, the vibration directly on your anal rim is making it quite loose.

The beautician notices that you slowed down because you were lost in thought and she pushes your head against her pussy. You go back to licking faster than before and you start teasing her butthole, pulling on the buttplug until it's half-way out just to push it back inside until the safety knob disappears, she then pushes the knob out and your repeat.
You hear her breath quicken, but she maintains her composure pretty well.
