It's all too much...

She suits her words and strokes your cock. Her small hands afford her the ability to double pump, popping your head into her cute little plump lips and sucking the tip while she works your shaft.
"Here." You reach into a nearby vanity drawer, pulling out some lube. "This should move things along. We don't have a lot of time..."
She pops the bottle, drizzling the lube on your cock. "Can I still...I mean...is it bad to put it in my mouth after..."
"It's non-toxic, honey. It'll probably taste a little weird to you but..." you groan as she attempts to itch her tonsils with your dick head. "Fuckkk....Allison....you got to work....your way up to that..." The poor girl is gagging and spitting up on your dick, her eyes are bulging and watering intensely. "Alli..." she won't stop...she continues to **** her throat and stroke the base of your shaft. Okay...if she's going to insist.
You grab her wrist, guiding it to your hip. "No hands, honey. The best girls can go no hands." You put your own hands on the back of her skull.
"Allow me to help you out." You apply steady pressure, and start to fuck her throat.
"RRR!!!! RRR!!!!" she gargles in alarm, her hands flailing on your legs. Her eyes are leaking tears down her face now, and her chin is just a mess with sticky saliva, and it's starting to coat her tits and legs. You release her skull, and she finally pulls off, coughing profusely and spitting onto the floor. "Fuck!!!"
You feel a pang of guilt, worried that you crossed a line. She looks up at you, rapturously.
"That was so intense...I... wow...I never expected you to be so forceful, Uncle James." She strokes your cock some more. "It doesn't really need the lube anymore." she giggles.
"Are you okay?"
"Yeah...I just needed to catch my breath." Suiting her words, she gets right back into giving you an amazing blowjob.
It doesn't take long before it's all too much. You're going to blow. Should you tell her? You look down at her face, and she meets your eyes with her baby blues as her cheeks puff out and suck in. Oh god...
