Cock blocked :/

My husband works 10pm-7am and comes home to sleep until 1 while the kiddos are in a summer program. Once they get home, there's no alone time. Needless to say, there's been a lack of knocking boots in our house lately. Weeeelll today, we finally got a free moment to get busy. Not 5 minutes into it, I hear a car honk. Then I hear some chatter. There stands his mother, and her friend, outside our bedroom window. LUCKILY we have dark curtains. They stood out there hollering," hellloooo, open uuuup!!"
