[M]y stepdaughter walked in my o[f]fice right as I was cumming.

Admittedly, it was my fault for leaving the door cracked. But then again, I wasn’t in my office for the sole purpose of masturbation.
After spending a few hours working on a paper, I noticed that I was becoming more and more distracted by a persistent erection. So I decided to take a break and enjoy a fap. I went over and lay down on the couch where I do my reading, fished out the ole purple headed yogurt slinger, closed my eyes and let my imagination take me away for a moment.
Right at the moment of orgasm, I quickly grabbed my towel and discharged a weeks worth of stress into it.
But while my dick was pulsing something caused me to look at my door, and standing there watching me shoot semen into a rag was my 19 year old stepdaughter!
I was paralyzed. I couldn’t react fast enough out of shock and due to the fact that I was in the midst of erotic rapture. She didn’t say anything, just closed the door and left. I have no Idea how long she was there watching me.
This occurred last night. I haven’t faced her yet, and I am not sure how either of us are going to react moving forward.
Background: my wife and I are separated, and my stepdaughter chose to live with me while attending university. We actually have a wonderful relationship. Sometimes I get the feeling that she is almost flirtatious, but then again, she’s just got a bright, bubbly personality.

But she just watched me cum! I mean, I know everyone is bored in this quarantine. But who watches their stepfather masturbate?

What. The. Fuck. Do. I. Do?
