Karen loved cum. She loved cocks of course, and preferred bigger over smaller, but most of all she loved cum. She loved knowing she had caused such a reaction in a man so as to make him orgasm, she loved watching it explode out the end of a hard cock, she loved the taste of it as it spewed into her hungry mouth, but most of all she loved to feel it as it shot up inside her pussy or ass.
When Karen was in university she had a bit of a reputation. Being brought up a good Catholic girl she was trying to save herself for marriage, but after the first time she held a boy's cock in her hand and watched it explode as she jerked it off, she became a popular date as she pretty much would jerk off anyone just to see and taste his cum. Yes, she quickly learned the easiest way to dispose of cum was to swallow it, so she would catch as much as she could in her hand and then lick it all up, or lick it off her lucky date's chest. That was in her sophomore year - in her junior year she first began sucking those dates' cocks as well and always swallowed, or at least swallowed as much as she could, licking any remnants from her hands seductively in the hopes of getting a second taste before the night was over.
Once she was a senior and sharing a house with 4 other students inevitably she picked up where she left off, with the added freedom of being away from home and living in a coed environment. She discovered that one of her housemates had a particularly large cock, larger than any man she had been with before and as it happened, they had a lot more in common and began dating. One thing that made them compatible was his open mind about Karen's fetish and allowing her to indulge when she felt the need or desire. Given how much cum she was getting on a daily basis from her boyfriend, she didn't have as many regulars as she had before but she certainly lived the cliche of sucking off classmates in the stacks of the library when the opportunity presented itself.
Inevitably, she found herself invited to a party where she was the only woman and there were a dozen horny 21 year olds. They were all fit, good looking and thankfully well groomed so that she didn't have any gross stinky cocks shoved in her face. She knew before she got there the likely outcome so it wasn't exactly a surprise and she was actually looking forward to the challenge. They all hung out in the living room drinking and partying, and taking turns dancing with her. She wasn't shy about feeling their cocks while dancing and soon she found herself in nothing more than her panties, with a couple of guys sandwiching her while she stroked both their cocks. The first time this happened she crouched down and began alternating between the 2 cocks in her mouth and while she was swallowing the first load the second guy exploded all over her face and hair.
A dozen horny young men with a very sexy and willing woman ready and willing to service them can produce a lot of hard ons and a lot of cum. Karen did her best and managed to get through the first round with all of them, but by the time she was half way through the second round she was really starting to slow down. Unfortunately for her, the guys were still horny so they began teasing her that she had another way to satisfy their needs. She had so far been able to put off her boyfriend on going all the way but now she found herself with 6 hard cocks still needing draining, and 2 of them really intriguing her as they were even bigger than her boyfriend. As she was sucking on one guy someone pulled her panties aside and began rubbing his cockhead against her soaking wet slit. Karen had exceptionally large labia and the boy took delight in seeing how they extended even more as she became even more aroused. Finally he pushed and she had her very first cock inside her. To say she loved the feeling was an understatement. Soon she was pushing back trying to get more and more of his cock inside her. When he came and she felt him explode inside her she came herself and her pussy clamped tight around the cock milking every last drop from him.
By the end of the night all 12 guys had fucked her pussy at least once and 4 even took her anal cherry. When she woke up around 7am everyone else was passed out so she decided to slip out and head back to the house before anyone else woke up and wanted to fuck her again.
I woke up around 8am and immediately checked my phone. I knew Karen was going out last night but I hadn't heard from her so I was a bit worried. There was a text from about 1am assuring me she was fine and that she was just going to crash at her friend's place and she would be home in the morning. I was relieved she was okay and began to fumble about getting ready to go shower. I looked out my window and saw a car out front with Karen in the front seat talking to an older guy. I saw her head disappear into his lap and can't say I was surprised since I knew how much she loved sucking cock and I never begrudged her of her need for cum. After a couple of minutes I saw her head reappear and then she got out of the car. I was surprised to see that all she wore was a man's dress shirt and the driver got out of the car and was following her inside. Curious, I waited a couple of minutes and then quietly made my way over to her room and put my ear to the door. I heard her thank him for the drive home and the use of his shirt.
"You are very kind saving me from a pretty embarrassing walk of shame this morning. I guess I could have Ubered but I'm not sure how the driver would have felt about a naked woman in his backseat."
"He would probably want to fuck you, just like me"
"Really? Again? Even with all the cum you know is inside me?"
"I think it's sexy knowing you have so much cum in your pussy. You would be my perfect girlfriend"
"Careful what you wish for. My boyfriend doesn't mind me sucking off a few extra cocks but believe it or not 12 hours ago I was a virgin and I don't think he will be very happy finding out I gave it up in a crazy gangbang."
"If he doesn't want you I would be honored to have you"
"You're sweet, and you do have the biggest cock I've ever seen so stayed tuned, I might be calling you later today! Thank you again and here is your shirt"
"Damn you look sexy. I've never seen a woman with such a sexy pussy. I really need to fuck you again"
"You need to be gentle. Tell you what, sit in that chair and I will ride you until you cum inside me. Your cock is too delicious to say no to."
It went quiet for a bit and then I could just make out the two of them breathing heavily. Karen began to moan as she orgasmed on his cock but he kept going and going.
"How do I make you cum? My pussy can't take much more"
"I need to be on top"
"Fine, just hurry. And please, try to be quiet"
