I am not that flexible. I rather wish I was.
One of my persistent fantasies is a Dominant who wants to modify my body. Not in a creepy way, but improve it. Make me more flexible, so he can tie me in more interesting ways. Or maybe stronger kegel muscles so that I can please him better when we fuck. Or stronger hands so that I can give deeper, longer massages.
I want him (or her) to mold me physically so that I am more pleasing and more capable. Decide on a exercise routine for that purpose. Monitor the results. Enforce consequences for non-compliance or not meeting certain goals.
Partly, it’s the focused control that interests me. Partly, it’s the genuine desire to be more pleasing, and to get to that point interests me. Partly, it’s the idea that the person has the right to modify me that interests me.
I so deeply, truly want to be molded. Not to make me no longer who I am. But to make me my best self possible, by both of our standards.
