You don't....

You feel your cock escape through the top of your pants as Bianca's eyes move to it longingly. She uses her other hand to unzip you and lets your bare dick out, and it throbs as she continues to finger your ass in the dark corner of the club.

You move your leg so it covers what you're doing a bit more, and you start to pull her pants down more to give yourself more access. You use your other hand to graze your fingertips across her balls, and you hear Bianca moan in your ear.

You grab the lube that Bianca used and spread some on her cock to help jerk her off. As you move your hand up and down, you feel some precum across the top as your reward.

Bianca then slides a second finger inside you!

Despite the pain, you miss how good it is to be filled up as Bianca then slides your pants and underwear to your knees, revealing you to anyone watching.
