Never underestimate the power of teaching your sub that you love to hear when they're grateful, to say thank you properly in full sentences with why they're grateful, and encouraging them to express their gratitude as early and as often as they can no matter how perverted it is sometimes.
"thank you for cumming in me."
"thank you for writing your name on my chest."
"thank you for correcting me."
"thank you for making that phone call for me."
"thank you for tying me up."
"thank you for letting me have alcohol."
"thank you for letting me make your drink."
"thank you for driving us to dinner."
"thank you for bruising my ass."
"thank you for fucking my face and turning off my brain."
"thank you for enforcing my bedtime."
"thank you for being my dom and everything you do for me."
Kinky gratitude is a helluva drug. Doms need gratitude kinks like subs need praise kinks.
