Millie gives me a handjob

Millie is jerking my cock very slowly and gently under the blanket, and I feel her second hand slipping in under the blanket, and this hand she uses to start massaging my balls.

I hear Millie whispering to herself:

"This is so wrong, he is my step-son, but I cannot help myself."

I am really struggling to control my breath and pretend that I am sleeping, and I feel my hips start to move with the pleasure of Millie's gentle tugging on my cock.

Millie must be sensing my pleasure through her hand, and she starts jerking my cock a bit faster, and squeezing my balls in a way that she must have read about in the Kama-Sutra.

She briefly let's go of my balls, and pushes my blanket aside, and then her hand returns to my balls, her other hand stroking my cock.

The pleasure is getting really intense now, and I cannot keep from moaning loudly with pleasure. Millie whispers:

"Matt, if you are awake, pretend you are sleeping."

I don't answer her, but I feel I am about to cum, and Millie feels my balls tighten, and whispers:

"Cum for me Matt."

Hearing that, my cum spills into my step-mom's hand, and she slows her jerking me down to a slow pace and milks out all my cum.

Millie takes her hand of my cock for a while, and then I feel her tongue on my stomach, and I realise she is licking up the cum that has landed there!

She then takes a tissue and cleans me up thoroughly, then pulls the blanket back over me, and quietly walks out of my room closing the door behind her.

My eyes have been closed throughout this entire amazing experience, but as soon as I hear the door closing I open my eyes. I look around for a while, smiling to myself, and then I turn to my side, and this time I have no trouble falling asleep.
