Being Vocal for your Sub as a Pleasure Dom
Dirty Talk, Praising, and fixing that good girl kink a sub has can be difficult but comes easier with more and more practice and communication. As a pleasure dom, I get turned on by knowing my partner is thoroughly enjoying themselves. This means complimenting them and praising. Something where allowing your more "primal" side to come out can help with.
Be vocal, tell them how good they're doing, praise their body and mind, how proud they're making you. And then take it away in little moments with "control/strength" to show the Ying and Yang of both pleasure and dominance.
