Take control

You push her avainst the wall and pin her. You lift her dress up just enough to put your hand underneath and reach in between her legs. Your hands find her completely soaked panties.

"You've been a tease all evening, now it's my turn to give you back a little," you say as you slowly start running her clit.

As soon as you start rubbing she struggles a bit, "no not here."

You pin her again and say,"if the cab is fine and the lobby is fine then this is fine too."

You push your finger up her vagina even though she tries to resist it. She tries to push your hand off but you continue rubbing.

You push your middle finger up her vagina and rub her clit with your thumb as her resistance breaks and she starts moaning louder. You start squeezing her tits with your other hand as you continue fingering her harder.

The lift starts moving up again but you don't stop. "The lift is going to reach the floor in 10 seconds, that means you have 9 seconds to cum," you say as you push another finger up her vagina and start fingering her harder.

As the lift continues to go up she starts moaning louder as her orgasm builds. You continue fingering her harder and harder as the bell rings and she cums in your hand. You pull back right away as the door opens and the two women waiting outside to enter stand shocked as Pam just about opens her eyes and catches her breathe again.
