"Should we go back to bed after breakfast?"

I suggest, thinking that spending the day fucking Millie would be a great way to spend the day, then I wonder if she will still let me fuck her once in a while when my dad comes back.

My thoughts of a great summer spent secretively fucking my big titted step-mom are sadly erased very quickly, when Millie says:

"Matt, last night was us both releasing the sexual tension between us, you did realise that was a one-off, right?"

My heart feels like it is sinking, but I try to act cool and casual, like a sexually experienced grown-up rather than the novice 18 year old I am, so I say:

"Naturally. Was just suggesting that we rest a bit, in bed, I mean."

Millie gives me a look that shows me that she knows that I am lying but she is going to let it slide, and says:

"Good we are on the same page that last night will not be repeated. I'm going outside, you think about what you want to do today while you finish your breakfast, then come find me."

With that she walks outside, and I watch her ass swaying as she walks, thinking to myself that I wonder if she takes it in the ass.

I take my time to finish my breakfast, then I go outside. Millie is on one of the sun loungers reading a magazine, and when she hears me come out she looks up and asks:

"So have you thought about what you want to do today?"
