Tell her to use her mouth.

"Mmm...sounds good..." she licks her lips and gives your shaft a few prepratory strokes, then takes you into her mouth. She slowly draws back, looking up at you with her blue eyes, then takes you back in, all the way, deepthroating you with a little muffled grunt. She squirms in excitement and starts bobbing her head, red red lips wrapped around your shaft, going faster and faster, her eyes watching yours, one hand caressing your balls as she takes you deep in each time, her tongue caressing the underside of your shaft.

She senses you getting close and squirms around more. One hand cups her breasts through that tight little uniform, squeezing and kneading them, while the other continues to fondle you. "Mm-hmm, mm-hmm, mm-hmm," she issues muffled encouragement, eyes glittering, flushed with anticipation as you get closer and closer, and she bobs her head fast, blonde hair flying, kneading her huge breasts.

Finally you cum, exploding into her mouth. Her eyes go wide and then she swallows busily, trying to keep up with the flow as you come and come and come, some of it escaping her lips to dribble down her cheek as she swallows and swallows, her tongue milking you, her hand caressing your balls, trying to get every single drop.

When you finally finishe she falls back, face flushed and hair wild, and you can see her savoring the taste of you on her tongue as she pinches and twists her nipples through the fabric of her uniform.

"Mm...nice, Tiger. Very nice. But now I'm all worked up again." She licks a bit of white from the corner of her mouth and shivers. "Tell you what. Let's go get your payment for...services rendered, and then you can wait for me to get off work in an hour...if you want."

Back in the lobby you collect your payment and sit down in one of the comfortable chairs to wait. Looks like this had turned out to be a very successful venture, after all.
