Stepdaughter Caught Me Red-handed

When I have a moment alone in the house I'll often check the hamper for a pair of my stepdaughter's panties, jerk off to them, then put them back.

Yesterday she came home early from school because it was a final exam day. I wear headphones so I can enjoy the grunts, groans, sighs and whimpers of the porn clips I watch. My step-daughter must have heard either the sound of me stroking my wet, lubed cock, or the faint and tinny sound that escapes from headphones. She opened the door to her mom's and my room and caught me red-handed.

I've talked her down from telling her mom right away. I told her it would break up our family immediately. Most of all, I think it's fair that I have a chance to explain myself. I'll be working from home again Monday, she's done with school, snd and my wife works in-office, so Monday will be my chance to apologize.

Has anyone else ever been through a similar situation? What do you say to show it's just a fantasy, not something you would ever want to act on.

Thanks for reading. I am honestly panicking.
