I work for a large company with alot of employees nationwide, and last night one of the area managers had an “unofficial” Halloween event at his house last night. I wasn’t going to go since I didn’t have a date but one of my coworkers convinced me to tag along with her since she didn’t have a date either and I decided it would be a good networking opportunity to meet some people from other parts of the company. I threw together a quick costume with some stuff I had, just a cape and mask nothing special. So we get to the party, there’s probably about 150-200 people there in a very large house drinking and mingling. About an hour in things are pretty boring (think typical work party with upper management) and I excused myself from a conversation I was in to use the restroom. I walk toward the back of this unfamiliar house and find a restroom, do my business and head back to the party. As I’m walking down the hall and put my mask back on a hand grabs mine and a dark haired woman (my “date” has blonde hair) pulls me towards the door to the back yard. Completely taken off guard, I instinctively follow this woman thinking maybe something is wrong. As we rush out the door to the backyard I hear her saying something along the lines of “I was looking for you, I found the perfect spot… right over here…” but I didn’t quite catch the whole point of what she was saying. She pulls me behind a small shed (pool house, garden shed?) away from the party and immediately gets to her knees and says “I can’t believe we’re gonna do this here this is so bad” with the biggest naughtiest smile on her face as her hands are on my crotch and pulling at my belt. I tried to stammer out that I’m not who she thinks I am but it just came out “uh- I- uh- wait…” but my manhood was already half at attention and my thought process was breaking down in the heat of the moment. I decided fuck it, I’m just gonna go with it. She was a pretty attractive late 20’s female and she was excited to suck a dick so why not, right? She proceeds to open my pants and pull out my almost hard unit and immediately a look of shock comes across her face as she realizes “oh shit you’re not Cory!” (Fake name obviously). Immediately I feel horrible for not saying something and I try to apologize “I’m sorry, I tried to say something but you were moving pretty fast and…” I was reaching up and pulling my mask off at this point when she got that naughty smile on her face again and said “no, leave it on” and took my cock into her mouth. She proceeds to go to work on my cock, going as deep as she can and just being an all around slut of a cock sucker. At this point I’m stuck between complete ecstasy getting my dick sucked and complete panic trying not to get caught by her husband/boyfriend who’s probably looking for her by this point. After a few minutes of some amazing head I’m about ready to bust, I tell her “I’m gonna cum” and she just continues going to town like it’s her job. I instinctively put a hand on the back of her head and hold her in place as I drain my balls into her mouth. After a few seconds she swallows everything and tells me “You’re much bigger than him, this was fun. Thanks.” Flashes me a sweet little smile and struts back inside, leaving me standing in the garden behind a shed with my dick hanging out wondering what the fuck just happened. I get myself together and head back inside a minute or two later (as to not be seen too close together with mystery woman) and find my friend group. About 30 minutes later I happen to see her across the room holding onto the arm of a man about my height with a similar outfit and the same mask on. And I mean HOLDING onto his arm and laughing, joking, conversing, obviously playing it up as the wife/girlfriend to make her hubby look good at his company party. My date and I left shortly after, never spoke to mystery woman again or even knew her name or who her hubby was. I’ll be going to the Halloween party again next year.
