When Kevin got home that evening, he found Chrissy and Mark on the couch. They were far from each other, almost awkwardly so. Mark looked very casual, playing on his phone. Chrissy, on the other hand, was red faced and out of breath.
"Hey, Kev," said Mark, standing up, towering over Kevin. He flashed a cocky grin as he gave Kevin a friendly, but slightly painful, slap on the shoulder. "I gotta meet Beth for a drink- so..." Mark's smile got mischievous for a moment, "... Chrissy's all yours."
With that, he left toward the door, leaving just Chrissy and Kevin in the common room. There was silence as they studied each other.
"Um," she said, looking up at Kevin awkwardly. "Let's go to our room."
"Sure," said Kevin, a little confused. What had happened?
They walked in and she shut the door behind them. "Lie down." Kevin looked at her blankly. "Please," she begged with a hint of desperation.
Kevin, still confused, lay down on the bed. Chrissy stripped off her pants and her panties, climbed up next to him on the bed, and, without warning, straddled his face.
Oh god, he thought, she is absolutely soaked. Her whole inner thigh was practically glistening with it.
She began rocking on his face and Kevin eagerly began to lick along with her. She was moaning so loudly already.
Kevin loved eating her out like this- looking up at her huge tits, even though they were still in her baggy sweater, and feeling her buck against him with pleasure.
"Oh, my god," she moaned. "Oh, my god, Kevin, yes. That is sooo good. Keep going."
He was hard as a rock, trapped in his jeans. What had happened while he was out? Mark did something, obviously. The thought made Kevin even hornier.
He noticed her eyes were closed, tight. He gently lifted her off him so he could talk. "What are you thinking about, baby?" he said, before he dived back into eating her.
There was a beat while she thought about her answer. "Um, you, baby... how good you're eating me out..."
He lifted her again. "What are you really thinking about?"
"Um... are you sure... are you sure I should say?"
"Yes, baby," he replied between licks, surprised by how desperate he was. "I want to hear it. I like hearing it."
Her whole body shook as she answered. "I'm... I'm thinking about... Oh god, Kevin, I'm thinking about Mark."
His erection was painful in his pants. "Talk dirty, baby," he said. "Talk dirty to me... like you're talking to him." He dove back in, licking her desperately.
"Oh, god, babe... are you... are you sure?"
Kevin just squeezed her ass in encouragement.
"Oh god, oh god... oh Mark, fuck me. Fuck me, please, I want you to fuck me so bad." She was really grinding on his tongue now. "I want to be your slut, Mark. Let me choke on your dick, come fuck my tits, do whatever you want to me just... use me. Whatever you want!"
Holy shit, thought Kevin, she was being filthy. His cock pulsed, painfully hard in his jeans.
"Use me like a dirty little whore while my... My boyfriend is in the next room. Use me, let me feel that cock inside me, choke me, whatever you want. I want to be your little slut, please, please, oh god... I want to be your little bitch."
She grabbed the headboard and really grinded into Kevin. Kevin did everything in his power to keep up, pleasuring her all he could. She was close to a massive orgasm, he could tell.
"I want to suck on your cock on the couch while you watch sports on TV. I want to lick your balls in the shower. I want you to fuck my big tits when Beth's not in the mood. I want you to use me, use me, use me, oh God. I want you to fuck me, not just... not just because you want to, but just because you can. You can take me. You can take me wherever. Oh, god.
"Oh god, please, fuck me. Please use me. Oh god, please, please, please fuck me, fuck me, fuck me MARK!" she screamed. Her orgasm took over, causing her to clench down, squeezing his head between her thighs. Kevin could hardly breathe as she rode it out, shaking.
It has to be the biggest orgasm he'd ever seen her have.
Finally she came down from it. Her hands slowly explored her own body, squeezing and feeling and enjoying the sensations. With a few deep breaths, it was over, and she released her thighs, freeing Kevin from the world's best prison.
She climbed down next to him, out of breath. She immediately began kissing him all over his face. "Thank you, thank you, thank you," she said between each kiss. She held him tight. "That was sooo filthy. So, so good. Thank you. I am the luckiest girl in the world."
Kevin smiled at her, letting her enjoy this post-orgasm euphoria.
"Chrissy," asked Kevin. "What happened today?"
She turned towards him, snuggled against him as he lay on his back. Her huge tits were pressed against one side of his chest. Her smile was mischievous. "Whatever do you mean?"
"Please."
Her hand found his belt, masterfully taking it off with one hand and reaching the button. "Ohh, you mean between Mark and I?" The button popped open, and she zipped down his zipper. "Are you sure you want to know?"
Kevin nodded desperately.
"Well, okay. I can tell you about our little massage." She reached into his underwear and pulled out his cock. "Wow," she said with genuine shock, "you are already so hard!"
"Chrissy."
"Okay, you get your story." She began to stroke him, gently, slowly- almost absentmindedly. "So I was there, reading my book on the couch when Mark came back. He went to his room and changed, and came back, and his shirt was off. So he was just in his gray sweatpants. Now... I'm trying to read my book, right? I want to be good, but he begins massaging his own muscles, and... He was just looking really sexy, right? So I was looking at him a little bit. I noticed how his stomach has that... V shape. Like around his hips. I don't think I've ever seen someone with that in real life.
"He looks at me quizzically- he asks me, directly, if I'm checking him out. I blushed and apologized. He said he didn't mind, but asked me if I was breaking that rule. I told him that The Rule had changed, and I was okay so long as I kept my hands to myself."
"He asked directly about The Rule?" asked Kevin, his curiosity getting the better of him.
Chrissy nodded. "So, we're in there, a few more minutes, just hanging out. He put something on TV while I was reading, he was playing on his phone. Then, out of nowhere, he asks me if I would do him a huge favor. He was in a great deal of pain, he said, and was wondering if I wouldn't mind massaging him. I told him, no, at first- obviously that would be breaking the rule- but he came over next to me and showed me exactly where it was sore, and- I don't know, his smell kind of enveloped me, and he was so close, I just... I feel like I wasn't even thinking straight. That's when I said I'd check with you... and I did.
"So, when you gave me the OK, I told him I'd do it. He thanked me, and I told him to lay down on the couch. I kneeled right next to him and started massaging. And... wow. Those muscles. They're... insane."
"Yeah?" asked Kevin, his insides twisting with humiliation, jealousy and arousal.
"Oh, yeah. It felt like trying to massage iron, or something. But he told me I was making him feel good. His smell was... it was even stronger now. I was above him, rubbing all over his chest, near his arms. Across his biceps. He kept telling me how good I was making him feel, and the more I did, the more I kind of... lost myself. I couldn't believe how defined each muscle was. Sometimes I found myself running my fingers along them, rather than just massaging, you know? ... Wow, your cock is like... pulsing. I've never felt it like this."
