Post-handjob relaxing

I keep my eyes closed as I'm coming, feeling the pleasure as my cock jumps in my step-mom's hand. Then, I feel Millie's hand on my cheek, and I open my eyes to see Millie's face close to mine. We look each other in the eyes for a moment, then Millie closes her eyes, leans in closer, and her tongue gently touches my lips. I open my lips slightly, and our tongues meet, and we share a protracted kiss.

After a while, Millie breaks away from the kiss, moves her head away a few inches and says:

"Matt?"

"Mmmhhmm?" I mumble in reply.

"Matt, I don't like to sleep alone, so do you want to sleep in here tonight?" Millie asks.

I cannot believe what I am hearing, so I just reply:

"Sure."

I must have sounded too enthusiastic, so Millie says:

"Just sleeping Matt, you promise?"

"I promise." I reply.

"Great." Millie says, getting up and turning the lights off.

The room gets dark, but not completely, and I see the silhouette of Millie's figure against the window as she slips out of her bathrobe and crawls into bed.

"Good night Matt." Millie whispers and gives me a light kiss on the lips.

"Good night Millie." I whisper back.

Millie rolls over on her side, and soon I hear her breathe rhytmically, but I am laying there awake, my cock hard at the thought of my busty step-mom being nearly naked next to me.
