Millie shows me her tits

Millie unclasps her bra, but holds it in place with one hand over her breasts, looking at me, smiling as she sees the look of anticipation. She waits a few seconds, then let's her bra fall to the ground, revealing her big tits.

I just stare at them in their nude majesty. They are so firm looking, and her light brown nipples are pointing straight at me. I feel my cock twitching in my pants, and I reach out to touch them, but Millie pushes my hand away, saying:

"Only looking, Matt."

I move back, and continue to enjoy the display of my step-mom's gigantic breasts.

Millie smiles at me, then says:

"So, is the mystery gone?"

"You have beautiful tits." I say in response.

Millie looks down at her tits, saying:

"Well, thank you, Matt."

I notice that my hand is squeezing my dick through my pants slowly, but I cannot contain it, so I keep going. I see that Millie notices, but she pretends she has not seen it, just looking at me smiling. Then I hear myself saying:

"Do lots of guys try to date you, since you have big tits?"

Millie bursts out laughing, saying:

"What sort of question is that?"

I blush, but then work up a bit of courage, saying:

"Have you had a dick between them?"

Millie laughs loudly, then looks at me, saying:

"You are getting a bit bold, are you not?"

"It's just that, it looks like, you know, they'd be perfect for..." I hear myself stutter.

Millie looks at my hand stroking my cock through my pants, and says:

"Show me your cock."

Without hesitation I stand up and drop my pants, my cock springing out and pointing straight at Millie.

"Wow, nice and hard already." She says, giving my cock an appreciative look, then says:

"What about your cock, Matt, has it ever been between a pair of tits."

I blush and shake my head.

Millie pushes her big tits together and says:

"Well, I have had plenty of cocks between my tits."

Without thinking, I start stroking my cock.
