Last night I went to a party with my girlfriend, got drunk, and lost track of her at some point. At like 4 a.m. I went to go tell the host of the party bye and walked in his room, I walked in on my girlfriend and another guy making out in bed, before I could process it was her I saw the covers moving up and down really fast and he started breathing really heavy and thrusted, that when I rushed out. The lights were dim and they were probably really drunk so they never even saw me. I’m pretty sure I walked in right as the guy was c******. I’m so embarrassed I don’t even know what to do.
