I have two pretty funny stories..
FIRST I was sharing an incall with another provider and my room was a wreck so I was using hers for an appointment. My client was sitting in a chair in the corner and I was giving him a very sexy lap dance... when suddenly the other girl's little black dog pushes the door open and runs in barking VERY LOUDLY. I tried to get the dog out but she hid from me! The other girl had to come and call her dog...so embarrassing!
SECOND I was at an outcall in Arlington with a really awesome client. He reminds me so much of one of my best friends so we always have a great time. Well he liked having the TV on in the background---it just happened to be playing Blades of Glory. Right in the middle of a very intimate moment, the little boy in the movie starts yelling "STRANGER DANGER!" and we both burst out laughing. It was hilarious but it ruined the mood
