"I'd like to go down on you."

I say it as sensually as I can.

Millie grins, showing her teeth, obviously pleased. "Oh, Matt. That's an amazing idea." She quickly sits up and brings her legs from under her and spreading them around my legs. She's grinning at me and licking her lips very sensually. I can see that her pussy lips glisten with her excitement.

I kneel between her legs and lean down, stretching out my legs behind me. I can smell her muskiness, and a thrill runs through my body. I'm going to lick my first pussy. I look up at my step-mom as I lean into her crotch. She's smiling down at me, tousling my hair. I turn back to her cunt and breathe in her aroma deeply. It's a gorgeous peach of a cunt. Then I lean down flick my tongue on her pussy lips.

Millie moans, and I see her eyes close as I look up. I start lapping at her pussy, using long strokes like she was an ice cream cone. She tastes wonderful, a little salty with a great flavor I'd never had before. I reach up and caress her huge tits as I go to town on her privates.

"Oh, Matt. I can tell you're not well-practised at this, and that makes me hornier that you're doing this. Your tongue feels amazing," Millie says as she slowly gyrates her hips, and her hands join mine to massage her tits. I dig deep in her cleft, pulling a louder moan from her throat. When I find her little bump above her slit, Millie squeals and her hips surge up, smushing her pussy into my face.

"Oh, Matt! Yes, keep that up. I love your tongue!" she says, panting as her excitement increases.

I start squeezing her tits and pinching her nipples as I twist my tongue, drilling into her pussy. No longer stroking my hair, she's now gently pressing my head deeper into her cunt. I suck on her clit, which makes her thighs clench around my head.

"Oh, yes! Yes! Oh, Matt! Make me cum, Matt! I wanna cum on your tongue!" she says, and then she screams as her thighs squeeze my head. I can feel her juices flowing freely out of her pussy, and I lick them up as best as I can. I keep licking and sucking until her orgasm subsides and her legs part to let my head go.

I gently fondle her tits as we both come down from this amazing time. I look up as I hear her pant. She's smiling at me with a hot glaze.
