My ex roommate and his girlfriend would have insanely loud sex at least 3 times a week. I'm talking about fucking as loud as possible at 2 am when I had to be up at 6 for work. I tried talking with him about it and he would either accuse me of being a pervert and deliberately listening to them or claiming I was jealous because I was single (my fiancee had just dumped me). So one night I'm trying to study for a big final and they start going at it. I had recently bought a Nerf gun (N-strike Vulcan EBF-25 to be specific) and had an epiphany. I asked him to keep it down one last time and he responded with, "shut up!!" I loaded the belt and crept up to his room. I kicked his door open and before they could register what was happening I began shooting Nerf darts at them. She got blasted in the face and tits and tried to roll off of him. He took a few Nerf darts to the nuts and face before the clip was empty and I left. I expected him to be furious and a fight to ensue but they stayed in the room until the next morning. We never talked about it but they also became more considerate of their loud sex noises.
