Silliness. No point to it. It’s like xeroxing your ass while taking a dump… nevermind. I just saw the point to it….

HAWT

Funny. But you can hardly pull off the uber-intellectual sounding narration if you don’t know how to pronounce “coitus”…

Just when I thought nothing can surprise me, here comes sex in MRI porn. I almost got wet watching that. It was somewhat… arousing. NZ Girls likey likey! Lolz!

Eeew. That was disgusting. It looked like H.R. Geiger’s Alien giving somebody a blow job.

Looking more closely… :^)

Either the man is pretty long, or the woman is pretty shallow. He bumps her cervix with every thrust.

Wow, that’s hot.

Rule 34 now expands to MRI porn.

Disturbing and kind of gross. And I was totally looking at the wrong thing - it took me a couple of seconds to realize the penis was actually a little to the left…

That looked sort of violent.

It focused just on the woman. I wanted to see some flapping testicles.

sweet jesus is that Laura Linney narrating?

My penis just inverted itself, and then it started crying. I didn’t think that was possible.

This almost ruined sex for me. Almost.

The still photos from this study are years old already. I’m surprised they could actually make a video. I didn’t realize that MRI can grab a full image so quickly.

ain’t it great to be a scientist? just write up a proposal and bam! you have yourself some naked people doing it in a big magnetic tube.

I really needed new ‘material’. This fits the job nicely :)

This is even worse than those night-vision sex tapes. What celebrity scandal is this supposed to be, again?

Can someone tell me who that bald man covered in silver paint who is shining a flashlight on the scientist is? Right around the 2:00 mark. Because that is what I’m focusing on right now.
