[minovskyy]

yes this is an exploration of guilt and culpability but it could also be a sex thing if you just give me a minute

if you hit a girl's cervix hard enough it resets her brain like an emergency button

[mastersoverminds-6]

I have an idea! How about I choke you with my cock until your brain reboots into safe mode. Then I can tinker with all of your brain's security settings until you're nice and compliant~

I love that tipping point in a breath hold, when you’ve held it for so long that your heart just- stalls. And suddenly starts beating slower and more forcefully, more labored. Like each beat is its last desperate cry for oxygen. Ugh, it feels so good every time. (the breath hold starts at 0:16 and I hold it until 1:45)

"It's in your heart." Love dialog like this. Wish writers would include more of it. That always seems to be a missing element. Good verbal descriptions to further stimulate the imagination.

"Put your hand on the blade. Do you feel her heart beating?" Perfect touch

You know when your heart over extends its beat and you feel it g u l p blood like it filled up too much and it has to pump once really hard just to gulp it down and then go right back to normal? G o d it feels good sometimes.

Decided to try a push method I’d seen on here, to try and make my heart act up since it’s being stubbornly calm and steady today. Basically you do a push while standing, then crouch down as you exhale and hold your breath there. My first push was so intense, I started seeing stars and my legs got weak, but I stayed standing. I managed to hold the push for nearly a minute and then crouched down as I breathed out.

Feeling my heart pause for so long between each beat was so fucking fun oh my god. And those beats were so forceful they felt like a fist was beating on the inside of my ribcage. It was so beautiful to hear and feel my heart struggle like it did… So much so that I immediately did it all over again a second time >;)

> Ouaauhhh . hello sailor

Listen to my heart as it fights to pump correctly, skipping away in my chest as it begs for your mercy after each experiment have only worsen its condition.

Just look at her, how pathetic it can’t even beat a minute without stumbling over itself… just imagine how bad can it get? It’s calling for another experiment…

|| Recorded this when my heart suddenly went crazy… wonder if I can record more… sorry for the bad quality! Hope you enjoy my failing little beats…

Also, to clarify! There was no pressure involved or anything like that, it really just went crazy
