Post-blowjob relaxing

Millie looks down at her cum-covered breasts for a while, then looks up at me, giving me a brief smile, then gets up and walks to her room and I hear her turning on the shower.

I stay seated, just enjoying my post-fellatio moment, and after a few minutes Millie comes back out, wrapped in a towel. She smiles a brief smile, then says:

"Matt, I'm quite exhausted, so I'm going to bed if that's okay with you?"

I nod slowly, really enjoying Millie asking me for permission to do things. Millie sees me nod, so takes that as me saying "yes", so says:

"Good night Matt."

"Good night Millie." I reply, then Millie heads to her bed room.

I stay awake for another hour or so, watching a bit of TV, then I go to bed as well.
