My boy didn't have to ask, if he saw me getting naked and laying on the bed he knew we were going to play. He only ever initiated it outside of the bedroom in one situation. If I came home from school and no one else was home, he'd greet me at the back door and after "saying hello" would run upstairs barking. he'd bark until I followed him to find him jumping around on my bed, wagging his tail with his red rocket starting to poke out. He knew I could not resist and in a matter of seconds I would be naked under him getting covered or filled with his cum.
