Me, Hunterdnrc, frost, and Reflectant were screwing around in a build server one night, and I started to build a vortigaunt piggyback ride vehicle.
Eventually it turned into a Vortigaunt blowjob machine.
Reflectent took the screenshots and compiled it into a Gif, I posed it and held the chair up, Frost was the blowjob recipient , and Hunter was off screen being AFK.
It was pretty lulzy. No online session of Gmod will ever amount to that one.
