Dirty
Billy woke up in the middle of the night, thirsty.
Instead of going to the kitchen though, he goes to his parents’ bedroom, while they were about to have sex and his father had a condom in his hand.

"What are you looking for?" Billy asked.
"Aw, well..hmm.. I’m looking for a little mouse!" the father lied.
So, Billy spontaneously: "Why..? To “jump” it..?"
