Julien has been playing the perfect boyfriend to Shane for a while now, but Julien has gotten bored of normalcy.
Julien has been having sex with Shane for a while, but Shane never showed any signs of getting muscular like Julien thought he'd might from his cum. Julien expressed to Shane that he wanted to spice things up, and Shane thought he just meant like dress up or verbal domination, so he suggested Julien can treat Shane like a dog and also to start calling him slurs.
Julien tried out the verbal domination part, and he enjoyed it quite a bit, but it didn't quite have the effect that seeing Shane grow would do. Maybe next time it will be different?
