Watching a movie

Millie picks a comedy, and as it starts on the TV screen she walks around and turns the lights off, then sits down next to me on the sofa. Millie snuggles up quite closely to me, and wraps herself up in a blanket. The movie starts, and we watch it in silence, then after a few minutes Millie asks me if I'm cold. It has gotten a bit chilly, so I nod, and Millie then wraps the blanket around both of us.

We watch the movie in silence, it is actually quite funny, so Millie is laughing loudly, then I feel her hand resting on my thigh under the blanket. I peek at Millie from the corner of my eye, but she is fully focused on the movie. We sit like that for a while, then I work up the bravery to put my hand on Millie's thigh. Millie does not react to this, she is just laughing at an awkward scene in the movie.

We stay like that for a while, each of us having a hand on the other's thigh, then I feel a bit brave, so I start to slowly rub my step-mom's thigh with my hand. Then, to my amazement, Millie's hand starts rubbing on my thigh. I feel my cock starting to grow hard, and I start massaging Millie's thigh more intensively, and I hear Millie's breathing get a bit louder, and her hand moves to my crotch area, sliding over the lining of my shorts, probing around a bit, then closing around my cock.
