Consent goes both ways, by the sounds of it you may have made her think you were enjoying the night. You reciprocated even though you were uncomfortable.

Neither of you communicated properly. She didn't ask for consent and you didn't ask her to stop. Both you and her need to do better.

If something makes you uncomfortable, then PLEASE communicate that, FFS.

As a top/dom (whatever word you need to use), I always ask for consent but I also need to TRUST that my partner will communicate if anything makes them uncomfortable. Consent is active communication throughout the entire night, so if I get consent to touch my partner, I expect them to tell me when they stop enjoying it too. I can't ask for consent repeatedly every 10 seconds throughout the night, there needs to be communication the other way as well. If my partner lies to me and doesn't let me know when I'm making them uncomfortable, that destroys the entire night for me. Because my pleasure comes from my partner's pleasure. So if they are uncomfortable and hiding that from me, then yeah it hurts a lot.
