MRI images of sex
 

I can't imagine having sex inside an MRI machine, but some couple did it for the sake of science, so that scientists could examine the resulting images of sex as seen from the inside.

All in the name of science, of course. Enjoy.

It's not NSFW, I don't think.

Oh how very odd.

That's hot.

It's like witnessing a murder by stabbing.

Weird

I'm so fuckin' jealous!! he got a prize for making a bad porno!!
