this actually happened last thursday, but with the whole sex rule i'm posting today.

everything was going fine that evening, and things were getting a bit hot texting my long distance girlfriend, alex. as things usually went, we started sending pictures via snapchat, getting increasingly scandalous with each picture. it got to the point where we were both masturbating, and sending videos via snapchat to each other of it. the way it was working, we basically did one for one, where i sent her one and she responded with one. i sent one where i was getting really heated, but then for a good 5 minutes i didn't get one back. that's when i looked at who it got sent to. instead of sending it to my girlfriend, alex, i sent it to my gay male friend, alex. what's worse is i said in the video explicitly, "ooo yea, i'm stroking my hard cock for you, **alex**". 

i have class with this guy monday, and we sit next to each other in econ.
i fucked up.

TIFU by sexting to the wrong person who shares my GF's name
