A group of University of Iowa students learned a lot more about geometry than they wanted to when their math TA accidentally sent them a file attachment of her homemade porn, instead of answers to the homework. For example, they could clearly see that her boobs were elliptical. Maybe they were supposed to calculate their area? Here's what she sent over:

Looks innocent enough…But when her students opened it, there was no such homework key. There was only this:

HELLO. That's the TA having cyber-sex on Google+ Hangouts with her boyfriend. According to the students who received the little gift from God, the file contained exactly 100% photos and .gifs of the cyber-sex and 0% math homework. Total Frat Move, who gained access to the file, offered up this deeply arousing description of what was happening in the .gifs:

The images are from a video chat that is quite sexual in nature. It appears that two people are “cyber-sexing” from different locations using video equipment. Both are nude and, well, “engaging” themselves in a sexual manner. They appear to be having a grand time.

A grand ol' time indeed. Thankfully, her students immediately took to Twitter so they could share the wonderful news with the rest of the world:

University of Iowa spokesperson Tom Moore released a statement insisting that the whole thing was an accident and that the TA "regrets her actions." And we'd like to release this statement, "Where the fuck was she when we were in college?" Silly TA, that's why you name files things like "Google+ Hangout Sex Episode 103: Do Not Send This To Students Ever. Ever." Problem solved.
