Stupid ex wanted me back a few months after she broke up.
Told her we could try but she has to really put a lot of effort in it.
I lied. I never would want her back but I wanted to have easy sex.

We fuck and I push her into doing anal. She never wanted to do it before.

Push her into a threesome with my new fwb.

Push her into being a slut for me and my friends.

Enjoy her for a bit and then tell her that we don't have a future.
