Caught by the cleaning lady

We have a lady come by the house once every two weeks to clean the stuff my wife hates (dusting lamps, cleaning tub, etc). Some days I work at home and know to plan my naked exercise routine for later in the day.We were on vacation the week before so my wife re-scheduled the lady and didn't tell me. I was on the treadmill about 25 minutes into a 40 min run when the lady comes walking into the room. I'm hot, sweaty, and my man meat is flopping around like a runaway firehose. She dropped her cleaning supplies and ran out of the room.I quickly ran to the bedroom, grabbed some shorts and found her in a spare bedroom. She began apologizing as if she had done something wrong. I told her not to worry, that it was my fault. I think she was relieved to hear that I wasn't angry and I was glad she realized it was a complete accident.
