Cum on her face.

You pull out and and grab the nurse, bringing you to her knees in front of you. Instantly, she turns her face up, batting her eyes at you, cupping her huge tits and squeezing her cleavage together, opening her mouth and sticking out her tongue. "Cum for me, yes, all over my face, cum on my face, yes, yes yes..."

Your cum jets out, shooting across her face, some ending up in her hair blonde hair and on her white nurse's cap. You keep cumming and cumming, splattering white everywhere on the blonde's upturned face, across her red leps, over her tongue. She laps up everthing she can reach, squeezing her huge tits as you cum, and cum, and cum, and cum, covering her in your seed.

Later, on the street heading home, you almost can't believe what just happened. But sure enough, the money is there--and the memories. All in all, you'd have to say this counts as quite a successful venture.
