I struggle to sleep

I go into my room, and just sit down on my bed, feeling very turned on, but at the same time confused. I don't really know what to make of the conversation I just had with Millie, but eventually I start to feel tired, so I get undressed, and climb in under my sheets. However, I am still feeling confused, so as I lay in bed my mind wanders and I am not drifting of to sleep.

Over an hour must have passed, but then I hear the door to my room silently open. I look over, and see Millie's silhouette in the doorway. She is just standing there watching me, but it is dark in my room, so it will take some time to for her eyes to adjust, so I close my eyes and pretend that I am sleeping.

After a few minutes, I hear that Millie is silently walking into my room, and soon I can smell the scent of her perfume next to me, and also hear her breathing. It is amazing how the other senses take over when one's eyes are closed, I think to myself.

I hear Millie's piyamas ruffle, and the scent of her perfume has grown stronger. She must have knelt down next to my bed.

Millie stays still for a while, then I feel her hand move in underneath my blanket, moving slowly until she finds my thigh, then crossing it. I feel my cock starting to grow hard, and very soon I feel Millie's finger making contact with my cock. She slowly runs her finger over it, feeling its hardness. I hear her whisper:

"This is so wrong."

Then, her hand closes around my cock, and she starts to jerk it.
