TIFU by meeting the world's biggest piece of shit and inviting him into my house. Please listen straight guys!

I fucked up around 4:00am this morning. Being gay isn't all great. There are a lot of gay creeps out there...

So it's 4:00am and two hookups already flaked out on me. I want to go to bed but need to fap. Halfway to relief a guy pops up on grindr. I do a quick pic and stat check. He's decent looking and disease free so it's safe. I give him my address and wait. I really really wanted a blow job.

Guy arrives with some 420. We smoke and rage about the injustices of circumcision and the dangers of marriage. We get each other. He really opens up. Tells me a story of how he meets straight guys, blows them, and collects their sperm. It's really simple:

Fake account on Tinder, okcupid, whatever. He's got this hot girlfriend you see. She wants to do it with another guy. He wants to please her and is looking for a guy. He's sorry but can't bare to watch his girlfriend screw another guy. Still, he wants to be part of the three-way. He also needs to check you out. He can stop by the day before you screw his girlfriend. He'll blow you to complete the three-way and make sure your not a psycho. He's done; you're not a psycho. Tomorrow is on! Also, your semen has been saved in a bottle. It will eventually get added to this year's cum jar. Sadly the hot girlfriend never shows up.

I can't fucking believe I let this piece of shit into my house. I kissed him too. :( Guys, if someone asks you to suck his dick before you can screw his girlfriend, run.

TL;DR I met a truly horrible person and befriended him.
