"Am just being silly, come pick it up when you are ready"

I need to be discrete here, so even though she asks me to be clear, I stay discrete and text back:

"Am just being silly, come pick it up when you are ready"

She writes: "Ok, I finish work at 8pm so is around 9pm Ok?"

"Perfect, see you then!" I text back.

A few minutes before 9pm, Millie walks through my door, she works for American Airlines, and is looking very sexy in her uniform. Millie takes of her jacket and hangs it, and her big tits are straining her white blouse to the limit.

I hand Millie a copy of the term paper I have written for her, and she is delighted as she flips through the pages.

"Matt, how can I ever thank you for doing this for me?"

I know what I want to say, but instead I say:

"No problem Millie, friends helping friends that is all."

She gives me a big hug, her big tits poking into my chest.

"That you wrote this paper for me has to be our little secret Matt."

"My lips are sealed, I promise" I reply.

"Are you good at keeping secrets Matt?" She says and starts to unbutton her blouse. I look at her mesmerised.

"Do you like big tits Matt?" I nod. She has now unbuttoned three of her blouse buttons, I can see her white bra holding in her big tits under it now.

She keeps unbuttoning her blouse, she is finished, she holds it open to show me her bra. She pushes me down on my bed, sits on top of me, straddling me.

"Do you want to touch my big tits, Matt?"

She guides my hands to her breasts, I start to squeeze them. She reaches behind her, and undos her bra, holds it for a while for effect, then drops it, and her naked tits are in my hands.

They are amazing, even bigger than I thought, obviously fake but well done, very firm with brown pointy nipples. I am fascinated by them, and she can tell so let's me play with them for a small eternity with a big smile on her face.

She slides of me, starts to undo my pants, then jerks them and my underwear of in one motion.

"You like your cock sucked Matt?" She asks with a smile.

"Well, I sort of hinted that I would suck your cock if you wrote that paper for me, did I not, I had so much fun teasing you over text about it earlier today." She says and smiles, then licks the full length of my cock.

"Mmmhhh, you like that?" She says. Licks my cock again, sucks on my balls a bit.

"Get ready, for I am about to suck your cock like it has never been sucked before!" She says, as she puts her lips around my dick and deepthroats me to the hilt in one smooth motion.

She comes back up, looks at me, smiles, says: "Wow, big tits and deepthroats, what a woman!" Takes my cock in her mouth again, sucks it, looks at it appreciatively, sucks it some more.

She shifts position, looks at me, says: "Now it is time for some serious cock sucking!"

She begins to furiously deepthroat me, and it is making some very sexy noise, I cannot hold back any more, so I shout:

"Oh my god, I am cuming Millie!"

She hears me, gives me a thumbs up, and I cum in her mouth. I can see her throat moving as she swallows every drop of cum that I shoot in her mouth.

She stands up, looks at me, smacks her lips, says "yummy, today's protein shake for Millie Smith" and puts her bra on, buttons her blouse, puts on her jacket and walks towards the door.

As she exits she blows me a kiss and says: "Remember, our little secret..." then she closes the door behind her.

I am still laying on my bed in complete shock, but very pleased with myself.
