Yes, in her mouth

The orgasm is coming on too quickly and who could really stop such an eager and beautiful nympho from doing what she's doing. So instead you just grunt an encouragement at her and bring your hands to the back of her head. Helping her to pick up speed but also slide deeper down with each movement. Her lips are about as far as she can go and you can just about feel the back of her throat with each Bob of her head. Her hands have long been unable to find any space on your shaft and so it's moved to gently massaging your balls, which have been made fairly wet by the saliva dripping down from your well sucked cock.
You can't help but be impressed by her complete lack of a gag reflex as she effectively fucks her own throat. Her tongue having to just settle with moving around the base of your shaft.
You're now on the very cusp of orgasming so you make a split second decision. Grabbing her head you pull and hold her down onto your cock as you begin to cum into her mouth. Her eye open wide at first and glance up to you in confusion. But as you begin to grunt and she feels your thick cum shooting into her mouth she reacts.
Soon you feel her mouth and cheeks working to suck your cum down as fast as its coming out. The pressure adding an intensity to your orgasm as you slowly begin to come down. Releasing her head from your tight grip. This allows her to slowly slide back from your cock before fully pulling back.
She let's out a cough then a few smaller ones, clearing her throat, as she catches her breath.
"That was good... You're a natural," you offer rather flatly.
"Thanks... See you later?" she says as she begins to stand. A disappointed look in her face as she realises it's seemingly over for now.
"Yeah, I'll be in touch," you offer as she gets up and leaves and you collapse back into your chair in a post orgasm haze.
