Tell them you put some Juckreizpulver / Ameisen /whatever into their payamas and watch the show LOL

Why not join in with and have some fun and drinks? It doesn't have to be perverted. 

From the sounds of it you're bored and awkward about. Being drunk will probably fix that :P 

Off topic: yay, I understand all the perverted German comments. *learning language skillz* 

I understand your pain. 3 German girls in one place at the same time, drunk and in party mood? You poor thing. I've lived in Germany long enough to know just how harmful this can be to a man's sense of estetics... Close the door, go to sleep or take a walk and try to forget. Time will heal the wounds :P

A good story from a guy on a video game forum who probably looks and has the personality of Sheldon Cooper from the Big Bang Theory. Picture/video proof or it did not happen.

Go and jerk off. As soon as you are done, you won't give two shits about any of them.

huh? what did he say? his girlfriend has two friends visiting her and they do the typical stuff? what exactly sounds like a story there? he even said that some comments are like to expect on the internet but pretty unrealistic.

Get drunk with them,have an orgy (the getting drunk is your excuse) and then wake up smiling in the morning.Chances are you could do it again while sober.

jemand der zu so einer einer Zeit im netz rumhängt während 3 besoffene mädels bei ihm rumhängen kann wohl nur aus nord lüdenscheid kommen.

(wenn sie hässlich sind werd erst mal besser selber besoffen)

Wow, people in here watch wayyyyyy too much porn. Also, cool story, OP.

Like any guy who isn't rich can actually get a foursome with three hot girls.
