Office jerk off

So it's Monday and I was feeling horny and my gf is away at the moment so I had no sex this weekend. Didn't feel like working so I've been sitting my office reading the posts on this site. Had to do something so I got my cock out and jerked off and shot cum all over my desk. Cleaned up with some tissues and then my assistant comes in and asks what's that on my desk. I obviously missed a bit and she was pointing and some jizz. I said I didn't know so she takes a tissue and wipes it up. Now I wonder if she realized it was cum.
