I let my married neighbor finger me after a party once our spouses were asleep
Do you two mess around like this often?
I heard she wants to do it again.
You shouldn't cheat on your spouses. They would be hurt to find out that you went behind their backs.
That's not the case, I'm the injured party.
Cheating on your spouse behind their back would make them the injured party. Hopefully you understand how doing something like this could really make them upset.
