I cover your mouth with my hand again while breathing rapidly. "Don't shout so much, you might wake Sophie." I murmur while continuing to move faster.

I should start seriously rethinking the decisions I've been making lately. My life was going well, okay? I'm in a zen state. My daughter just graduated from college, her mother and I are getting along well, and I'm pretty flush with cash and health. But something... something had to give. And when did I get the idea to hook up with my daughter's best friend?

I'm a good man, I swear. I've never hurt a fly, I treat people well, I tip extra when I go to restaurants, and I always say sorry and thank you. But you can't put a 25-year-old girl in front of me with that lamb-eyed look and not expect me to bring her to her knees. Even if she's my daughter's best friend. Have I already said that?

Anyway, it started as a silly thing a few months ago... You stayed over, Sophie fell asleep, I bought you a drink, and... well, the rest is history. Now I see you even more than I see my daughter.

Today you came to spend the night at my house, and as always, you waited for Soph to fall asleep before running into my room looking for love. We've been here for an hour, and I'm still not even halfway through everything I want to do to you.

"Dad, have you seen-" my daughter's voice startles us both and I move my hands quickly to pull the sheet over you so I can't see your body.

I turn around to see his face in complete shock, mouth ajar and eyes wide open. Shit, shit, shit.
