My absolute bulletproof kink is spanking. I could get spanked forever. Just makes me melt.
My partner made a flogger (yeah, he had some leather lying around and just decided "hey, I'm gonna make this!" I keep telling him he could sell custom sex toys haha) and I love that as well. Especially on my back. Nothing beats hands, though
Some other fetishes/kinks:
-Biting the crook of my neck/shoulder
-Orgasm denial (both to me and to others. When I'm a Domme, I almost always do this)
-Edging others (goes along with the previous) or making them edge for me
-Worshipping someone's body
-Getting cum on me. My face, my breasts, my body in general...
-Having rope UNTIED at the end of a rope bondage session. It's like a... warm fuzzy aftercare kink.
Ugggh now I'm like... I NEED MY PARTNER IN MY BED RIGHT NOW but he's sleeping in my metamour's room ;___;
