I wish I could hold a pets head very close to my mouth. I'd ever so gently lick at their outer ear while they tensed up, trying not to squirm in my grasp while I gave them some veryyyy uncomfortable attention.
If they did try to move I'd grip their head harder, reminding them exactly who is in charge. I wouldn't be surprised if they started to whimper when they felt my tongue start going deeper.
Down deep into their ear canal, the stretch almost painful but too overwhelming to really be able to process if what they were feeling is pain or pleasure.
The pressure would get the worst when they feel me just about to enter into their skull. Their blood would be pounding in their ears and my hot breath right outside would probably be making them drool and squirm by now. My grip stays tight on them as I prepare to penetrate their body through a hole that was never meant to be penetrated.
The pressure would grow and grow until *pop* like that my tongue has made it into their skull, their poor brain is defenseless now. My pet by this point is absolutely limp, the pleasure and heat of everything overwhelming them into a nearly comatose state while I have my fun.
All my pet would be able to do then would be drool and leak while my tongue explored every ridge and crevice of their brain. Nothing would be safe from me. My tongue would dig out all their memories and emotions and turn them completely blank.
At this point I wouldn't need to grip their head so tight anymore, merely cradle them against my chest while I took care of the poor, drooly thing. I think I would have fun playing with the various groups of nerves in their body, making them twitch or cry out when I hit a good spot.
When I found a *very* good spot I don't think I would let up, I'd bully my tongue into their brain deeper and deeper to force as many orgasms as I could out of them.
By the time I finally do pull my tongue completely out of their body the first sensation they actually feel again is how tingly and spent they are. Their poor ear is sore and leaking in my saliva meanwhile their privates are dripping and soaked in their own cum. Their body can't help but shake from what it knows I did to it, even if my pet can't remember. I'd be sure to soothe my pet and help them calm down. Giving them plenty of water and a snack to eat before letting them fall asleep, with no idea of what their master had just spent hours doing to them.
