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.
