I take my dick out

Hoping that it will turn Millie on, I unbutton my pants and take my dick out. It is rock hard. I slowly start to stroke it while looking at my step-mom, but rather than looking horny she looks horrified.

"You like it?" I ask, trying to reach for Millie with the hand that is not stroking my cock, but Millie takes a step back so that she is out of my reach.

I let my hand drop and look at Millie, she looks like she is in complete shock and is just staring at my cock, which I'm slowly stroking.

"Why don't you kiss it?" I say, looking Millie in the eyes, then looking down at my cock.

Millie seems to get her composure back on hearing that, and she turns her back to me, saying:

"Matt, just go to your room."
