I rather love weekends when my children go to visit family members, or when we can manage to schedule them both with a sleep-over on the same night. Opportunities to stay in hotels overnight are much enjoyed as well. Sometimes though, parents have kids in the house when urges which refuse to be deferred rise up.
On those occasions the radio/CD player we keep in our room proves itself indispensable and though we may not use the D rings he installed in a doorway, there are claws and teeth, and dark, hot fantasies whispered that are ever so much louder in our minds than they can be in the quiet stillness of a school night in an average suburban home.
Just as is true for everyone, we find ways to do what we really want to do.
