"Can you give me a blowjob?"

I say, looking up at Millie.

She thinks for a second, then says:

"Okay."

My heart skips a beat on hearing this. Wow, my big fitted step-mom just agreed to suck my cock!

In front of me, Millie slowly drops to her knees, looking me in the eyes as she does so. Her hands reach for my belt buckle, undoing it, then she unbuttons my pants and slides them and my underwear off slowly.

My cock is right in front of her face. She uses her fingers to push it closer to her, then runs her tongue from my balls up my shaft to the top of the mushroom, all the while looking me in the eyes. I smile down at her, I have been hoping for this moment to happen for so long.

Millie kisses the head of my cock, opening her lips slightly, touching it with her tongue. She then moves down again, and again runs her tongue all the way up my shaft to the tip, then whispers:

"Merry Christmas Matt."

Then she opens her mouth and takes the head of my cock in.

I let out a groan and raise my hips, pushing my cock upwards into Millie's mouth. Millie does not object, allowing my cock deeper into her mouth. We hold still like that for several seconds, then I move my hips down and Millie follows them down with her head, holding my cock in her mouth.

Millie then moves her head up, then down again, and starts a slow bobbing motion. I groan with pleasure, she is great at sucking cock, much better than any of the college girls, I think to myself.

Millie now starts to move her tongue against my shaft as she is sucking, creating an amazing sensation as she simultaneously lets out little moans, making my cock vibrate in her mouth. Again I groan with pleasure, using my hand to caress her cheek, whispering:

"This feels amazing Millie."

So far, Millie has only taken about two thirds of my cock into her mouth, but now she starts pushing deeper. I feel the tip of my cock pushing against her throat, then her throat opens up, and the head of my dick goes down her throat. Millie now has the full length of my shaft in her mouth, holding it still, her tongue reaching out of her mouth, touching my balls.

Millie then moves up about an inch, my dick head escaping her throat, then she pushes down again, taking me into her throat again, making it feel like she has a second mouth in her mouth, sucking on the head only.

I groan with pleasure as Millie continues this for over a minute, then she moves her head up, her hand grabs my shaft and she starts jerking it.

I feel I am very close to cuming so I say:

"Can I cum in your mouth?"

"Mmhhmm." Millie replies, not missing a beat in her joint mouth and hand movement.

"You going to swallow?" I ask.

"Mmhhmm." Millie replies.

Hearing that puts me over the edge and my cock starts spasming, and I empty my cum into Millie's mouth. Millie just keeps sucking as her mouth fills with my cum, and keeps sucking it for a few seconds after I have emptied my load.

Millie straightens her back, looks at me and opens her mouth. It is full of my cum. Her mouth closes, I see her throat move as she swallows my cum, then she opens her mouth to show me, saying:

"Wow, so I got a white Christmas after all." Then she starts laughing, saying:

"Merry Christmas, I hoped you enjoyed your present Matt."
