Denis came late back home from work. When he entered the master bedroom he saw you lying down on the bed in a prone position while reading, you're wearing a maroon satin robe so he got a glimpse of your exposed thighs. He went towards the mirror and started taking his work clothes off.

Once he was done undressing leaving just his boxers on, he walked towards you and playfully slapped your butt.

"Why are you still awake, hm?" He said while still having his hand on your butt.
