Millie's daughter has seen me fucking Millie in the ass

"Mom, what the fuck is this?" The young woman who I realise must be Millie's daughter Ashley screams from the doorway.

Both Millie and myself are shocked by her sudden appearance, neither of us have heard her come in.

Ashley is just standing there, staring at her mom. Millie tries to speak:

"Ashley, it is not what it looks like." She starts out.

"Well mom, dad has barely finished moving his stuff out of the house, and it looks like you are already inviting men in to fuck you in the ass!" Ashley shouts. Then continues: "But explain to me how this is not what it looks like?!"

Millie seems totally lost for words, so all that she manages to say is:

"I was not being fucked in the ass..."

Ashley just stares at her mom in anger, then says: "Whatever mom, you're just a butt slut!" Then stomps upstairs to her room and slams her door shut.

I give Millie a big hug to calm her, but she seems to be very relaxed about it all, surprisingly. She looks ahead of her with a bit of a blank expression, then says:

"Sorry about that, as you can see Ashley is taking this divorce pretty hard." Then continues: "Sugar, thank you for an amazing night and morning, but I need to get to work now, I will text you later."

I tell Millie that I've had an amazing time too, ask if I can shower before I head out, so I take a shower in the downstairs bathroom while Millie showers in her ensuite bathroom. I realise that Millie must be running really late, since she comes into the bathroom I am in with her American Airlines uniform on after just a few minutes and gives me a goodbye kiss and rushes of.
