Ask her to give you a blowjob

"Actually, I can think of something you can do right now."

"R-really?" she says, surprised. "What is it?"

"Why don't you give me a nice blowjob now?" At your request, her expression changes from adoration to disappointment. However, she keeps up the smile.

"Well, I did say anything, but..." she goes silent for a while. "Okay, sure. My place is pretty nearby."

"Here will do." you say, already unzipping your pants. You pull out your cock, as if you were ready to use a urinal. The lady looks hesitant again, but she crouches down to bring her face to your crotch level.

The first lick sends shivers down your body. She takes it into her mouth, evidently experienced. You're hardly surprised. A woman this hot probably had tons of guys hitting on her. She works your cock until it is fully erect, then started bobbing her head quickly. You close your eyes, enjoying the great service.

You feel your cock sliding into her moist, hot mouth. Her soft tongue massages the underside of your shaft while the head slides in until it hits the back of her throat. She expertly sucks you for several minutes, until you feel like your climax is coming soon.

Both hands on the wall, you thrust your hips forward, pushing your cock into her face. She has nowhere to retreat. You feel your cock penetrate the tight opening of her throat. Luckily, she doesn't gag and lets you do as you wish for now. You fuck her mouth. Already close to cumming, the extra tightness of the deepthroating sends you over the edge. You start cumming in her mouth, filling it with your hot seed.

You cock slips out of her mouth then, shooting more cum on her dress. Her face looks messy and wrecked.

"Did you like that?" she said, panting heavily.

"Yeah, totally." She takes some paper towels out from her handbag and cleans herself up, handing you a couple as well.

"Then, I'll be going home. Thanks for saving me." she says after she is done. Her tone was very businesslike.
