Millie wants me to worship her feet

I stand up and take off my swim suit, and Millie looks at my hard cock with an appreciative look, but out loud she says:

"Start jerking that little cock of yours."

I start stroking it slowly, looking at my step-mom laying on the sun lounger naked in front of me touching her pussy. We stay like this for a while, then Millie says:

"Sit down."

I sit down on the sun lounger, still jerking my cock.

"Sit so that you are looking straight at me." Millie says in a commanding voice.

I shift one leg over the sun lounger, so I am sitting with one leg on each side of the sun lounger, looking straight between Millie's legs at her pussy.

We sit like this for a while, Millie slowly touching her pussy, and I am slowly stroking my dick. Then, Millie raises one of her feet up into my face, saying:

"Kiss my feet."

I hold her foot with the hand I am not jerking my cock with, and start kissing her ankle, then up along the top of her foot until I reach her toes, which I suck on one at a time.

"That's a good dirty little boy." Millie says, then:

"Now the other one."

She raises up her other foot, and withdraws the one I have been kissing before. I start kissing the ankle of that foot, then go through the same steps with that foot as I did with the previous foot.

As I am sucking on her big-toe, Millie says:

"Control yourself and stop stroking your cock."

I do as she says and stop touching my cock. Millie moves her foot down, then spreads her legs wide and starts rubbing her pussy.

The sight of my step-mom masturbating in front of me is making my cock twitch with horniness, but I resist the temptation to go back to jerking it.

Then, I see Millie move her foot, and she puts it on my cock, moving it up and down, and then she moves her other foot to the other side of my cock, gripping it tight between her feet and using her feet to jerk my cock.

Millie starts rubbing her pussy more intensively, and at the same time she moves her feet faster up and down my shaft. My step-mom is moaning loudly now, and I feel that I am close to cuming, and Millie must feel this too since between moans she says:

"Do not cum yet Matt."

"I am trying." I respond.

Her feet feel so good on my cock, and I am struggling not to cum. Millie rubs her pussy very rapidly now, and she is raising her hips up slowly, saying:

"Almost Matt."

I don't reply, I am just looking at her feet jerking my cock, her naked big tits, and her fingers rubbing her pussy.

Then, when I feel that I can no longer restrain myself, Millie screams:

"Now Matt!"

I let go, and watch my cum shoot out onto Millie's feet, and I see her hips raising rhytmically up and down and hear my step-mom shout out her pleasure, she is cuming too I realise.
