Kevin nodded. "Yeah, I have no idea why I like this so much."
Chrissy cocked her head. "You sure you sure you want me to keep talking about this?"
"Please don't stop."
Chrissy smiled. "So he asked me if this broke the new Rule, and I said no, we decided to change it again- so long as everyone has their underwear on, we're OK. No worries about shirts or pants, but underwear stays on. He nodded after that and let me massage him for a while. I think, at this point, I was kind of enjoying it more than he was."
"He complained that the angle was a bit weird- me kneeling next to him- and that it looked uncomfortable, which it kind of was. So he asked if I could straddle him on the couch."
Kevin felt like he saw stars for a second so much blood was rushing to his cock.
Chrissy smiled, noticing his reaction. "I thought about resisting, you know, all the things I could have said, but... I don't know, I was just kind of lost in it and I... I wanted to. And it wasn't against the rules. Everyone would have their underwear on. It would just be little me straddling Mark. So... I said OK, and I got on top of him."
Kevin couldn't believe it.
"So, I got on top of him- I straddled him around his stomach. He's so much bigger than me, you know, so that was the best place to massage his chest. We tried that, at first, but he told me that my jeans were digging into him. And he asked if I wouldn't mind taking them off. With that cocky smile of his."
She began to stroke Kevin faster now, getting into her own story.
"I wanted to say no to that cocky smile, so he knew he couldn't get everything he wanted, but... there's something about obeying him, doing what he says, especially when I know it's wrong... it was just so hot. And it still wasn't against the rules. You said underwear, after all. So there was another layer to go.
"I almost did say no, but he cupped my cheek in his big hand, and said, 'Please? Don't you want to make me feel good?' And, I don't know, I just... I just did. I wanted to make him feel good, so... I gave in again. I stood up, peeled off my pants, and got back on top of him with just my panties.
But I'm soaked, of course. Like... dripping. As soon as I straddle him, he pushes me down so I'm pressed against his stomach. And he can feel it. ...you're sure you want to hear this?"
Kevin nodded his head, never so sure of anything in his life.
"So he got his hands behind his head, now, I'm straddling him, practically soaking his stomach, and all the while he's getting this chest massage. He's looking pretty kingly. He asked me, totally knowing the answer, if I was so wet because of him. I told him yes. Then he... he asked me if you ever get me so wet."
"Me?" asked Kevin.
"Yeah. You. He said, 'Does Kevin ever get you like this?'"
"What did you say?" Kevin was almost begging for the answer.
"I said 'Not like this, no.'" She looked at Kevin carefully, making sure he was OK with that, but Kevin was completely lost in his own arousal. "You like that? You like it when you're compared with him?"
Kevin nodded. "Yeah, I... I do."
She jerked even faster now. Kevin knew he would not last much longer if this story got any dirtier. "So he suddenly reaches around with one hand, and takes the back of my sweatshirt, and bundles it up in his hand so it's really tight on me." She sits up. "Here, reach around me with your hand, let me show you what I mean." Kevin did so, grabbing a handful of her sweater, pulling it in so it was tight around her. "No, more than that. Use both hands so you can see what it would be like if you had big hands like Mark."
His cock pulsed at the offhand comment, which Chrissy may not have even meant as humiliating. Why did it turn him on to be compared to Mark like that?
Kevin did reach around with both hands, and made her baggy sweatshirt tight fitting by bunching it in the back. You could basically see everything like that- her tight waist, the curves up to her huge boobs.
"Like that, yeah," she said. "He did that and said, 'Damn, you really know how to hide these things.' And there was something about that one hand at my back, tightening my clothes around me in his grip- like it felt like with one hand he would be able to pick me up like that- I felt myself get even wetter.
"Mark smiled at me, and asked me to start massaging him lower. And I did. Then he asked to go lower again. Which I did. Then he asked again, and I had to slide down on him. He said lower even more, and now I was massaging his abs. Until finally..."
Kevin was so close to cumming.
"I was on top of... him. Of his crotch. Of his... cock." Kevin could see she was getting aroused again at the thought, but he was way ahead of her, reaching new heights. He could not believe allowing them to have a massage had led to all this, but he was not complaining. "There was just my lace panties and a pair of gray sweatpants separating his cock from my soaking wet pussy."
She paused, mischievously letting this moment linger. "Please," begged Kevin. "I am so close."
"You want me to keep going?"
Kevin nodded.
"You want to hear what it was like when your girlfriend was straddling Mark's hard, fat cock?"
It took all his willpower not to cum right then, but somehow he managed, and nodded again.
"Well... okay. I landed right on top of it. I don't know how big it was, but it felt like I was straddling a baseball bat. Just as hard, too. I felt it, right on my pussy. He asked me, 'Do you feel that?' And I nodded. And he said, 'You like the way that feels?' And his hand started to explore me. They felt so big..."
"Bigger than my hands?"
Chrissy smiled, realizing how much Kevin loved the comparisons. "Yes, way bigger. He was exploring my body, and I was... I couldn't help it... starting to rock back and forth. Sliding my wet pussy on that hard cock of his. I kept going up and down but there didn't seem to be an end to it, it was... huge, and that was making me even wetter."
"Oh, god," said Kevin, losing control.
"You like hearing about that, huh? You like hearing about what a dirty slut I was for Mark, don't you? You want to hear all about how easy it was for him to get me all soaked, to get me on top of him just by asking, don't you? You had to take me on so many dates till I did that for you, but not Mark. Mark gets what he wants."
"Oh, god!" said Kevin, dangerously close.
"He felt me all over... he felt all over your girlfriend. He was groping my big tits while I slid up and down his cock. Well, I bet my tits didn't seem so huge in his big hands. Here, why don't you grab me like he was..."
She grabbed one of his hands and placed it roughly on her breast.
"... no, see, that doesn't feel right. He doesn't have little boy hands like yours, he has big hands. He was getting more of a handful of my big tits than this. It felt so good, baby, I've never been touched like that. Does that turn you on, hmm? Knowing I like his big hands over your little ones?"
Kevin nodded frantically.
"But his big hands weren't the star of the show, were they? No, all I could think about was the big cock between my legs. How hard it felt. How thick it was. How good it felt to slide up and down, feeling as much as I could of him. Dry humping him on the couch, it felt so naughty, so filthy, it felt even better than you and I fuck. Can you believe that, baby? Just dry humping his big cock was a good as you fucking me with your..." she hesitated before taking a risk "... small dick."
"I'm cumming!"
Kevin shot rope after rope as Chrissy kept jerking him. They all landed on his chest and stomach, covering himself in another massive orgasm.
Kevin took a few deep breaths and came down from his high, pleased, but full of confusing emotions.
"How was that?" asked Chrissy, handing him some tissues for cleanup.
"That was... that was amazing," said Kevin genuinely. "This shit is so hot."
"You're not mad?" she asked, genuinely.
His eyes shot over to hers. She seemed worried. "Why, because you straddled him?" He had a sudden realization. "Wait, I couldn't even make it through the story without cumming. Did you guys go any further than that?"
She blushed. "Just straddling! And the dry humping, I guess. But he reached a hand under my sweatshirt, and I just... realized that while it didn't break The Rule... it wasn't very much in the spirit of it, so... I told him to stop after that."
"He wasn't mad you stopped it?"
She shook her head. "No. He's a cocky asshole, but he's respectful. He took his hands off immediately and threw on a shirt."
Kevin thought about this.
"You're okay with it?" she asked. "I mean, I can tell it's turning you on. It's turning us both on. But... are we OK with where this is going?"
Kevin thought about it. "I am. This is crazy, but... I don't know. It just feels so good, and... I know I love you and nothing you do with Mark is going to change that."
Chrissy snuggled close to him. "Good," she said with a content smile. "I feel a little mean with all the comparisons..."
"No, it's... I don't know why. That's the best part. The more humiliation, the more I seem to like it."
He was about to turn and say something loving to his girlfriend, when suddenly, there was a sound through the bedroom door.
"Okay, guys! I'm leaving. Keep having fun in there!" said Mark. You could hear his smile in his tone. There was a sudden slam of the apartment's main door, and then, a harsh silence.
Chrissy and Kevin looked at each other, faces suddenly beat red. Mark had been here the whole time? He hadn't left earlier?
Chrissy turned on her back and covered her face in her hands. What could he hear from the common room? These walls were paper thin. Did he hear Chrissy screaming Mark's name, begging to be fucked? What about her telling Kevin the story? They weren't sure what he heard, but they both had the same thought: things were about to get much worse.
And better.
