I push my cock all the way in

Millie's pussy feels so incredibly wet and warm around my cock. It feels incredibly tight I think, but then I really have nothing to compare with, as this is the first pussy I have ever had my dick in.

So, thinking with my little head instead of my big head, I start pushing my cock deeper into my step-mom's pussy.

"Matt, take your dick out of my pussy, now!"

Millie screams as she feels my cock pushing in deeper. I now have my cock all the in Millie's pussy, and I just leave it there incredible waves of pleasure vibrating through my body.

Millie grabs my arms, and shakes them, saying:

"Matt, take your cock out of me, now!"

I just hold still, my cock buried all the way in Millie's pussy, and I mumble:

"This feels so fucking good!"

"Matt, I am your step-mom, I am not having sex with you!" Millie says, trying to make her voice sound stern, but I think I detect some weakening in her tone of voice, is she turned on as well, I wonder to myself, thinking of how wet her pussy is, so she must be turned on.

I slide my dick out slowly about half way, then push it back all the way into Millie's pussy again.

"Matt, stop fucking me!" Millie shouts, and starts wiggling her body under me, trying to shift her body away from underneath me. I am now pumping my dick in and out a bit faster, and am feeling amazing sensations in my cock, now I realise why everyone talks of fucking as an incredible thing.

"Matt! I am your step-mom, you need to stop fucking me!"

Millie screams loudly, and starts wiggling wildly underneath me, but this increases the amount of movement her pussy makes around my dick, and I am within seconds of cuming I feel, and four more pumps in and out of Millie's pussy I feel my cum emptying into my step-mom's pussy.

Millie feels this too, and screams:

"Matt! No!"
