Just cum in her mouth

As I feel my balls contracting, I am quickly trying to figure out what to do. Seems a bit weird to ask a woman twice my age whether I can cum in her mouth. She is certainly showing her experience with sucking dick as she is working away at me, and she must know about the cum situation that will arise if you suck a man the way she is sucking me?

Maybe announce: "I am about to cum!" when I am close?

My train of thought is interrupted by Millie shifting technique again, she pushes my dick as far down as she can, moves her tongue along the shaft like she is licking it, even though it is deep in her mouth, and then uses two fingers to massage the part of the shaft that is not in her mouth.

This feels amazing, and without warning I blow my load into her mouth and as my dick is deep in her mouth it goes down her throat.

Millie is totally unprepared for this, so she chokes on my cum, she manages to keep from throwing up, but coughs massively. Her lips are covered in a mixture of cum and saliva, it has dribbled of her face down on her tits, and she is furious!

She grabs her jacket of my bed, picks up her bag, and storms out of my room without saying a word or cleaning up.

I run after her, but she is storming away, and meets a group of students that live down the hall from me. Her cum covered lips and sweater tell the whole story, and they start cheering and high fiving me as Millie storms away
