Cheating on Kate

When she was being sort of a bitch, I'd been angry, but I definitely hadn't been mad enough that I wanted to ruin her relationship.

That hadn't changed. I didn't want to ruin my housemate's relationship. My best friend's relationship.

I didn't *want* to.

But in the morning, I just couldn't make myself go to class.

God, it sounds so pathetic, doesn't it? Like, I'm a grown woman. It's not like I was being held hostage by the president's daughter or anything like that.

There was absolutely nothing stopping me from going in that day.

...but his command had been ringing in my head all night. I had no idea what was going to happen, but...god.

I couldn't wait to find out.

The previous night I'd barely slept, and I stayed in my room the next morning when I heard Kate's voice. I couldn't face her.

I tried to tell myself that I wasn't going to do anything, that I was staying home because I felt sick, but I didn't even believe myself. It's not a good sign when you can't even convince yourself of your lies.

Instead, I just lay in bed, my mind racing as I tried to process exactly what was happening.

*Okay, Luke wants to fuck me, that's pretty obvious. And he wants to keep it a secret, which means he doesn't really care about me, just wants to score while still being with Kate, because he's a player and I'm a hot girl, and it's actually the perfect cheat. He doesn't have to worry about me telling Kate because he knows I don't want to ruin my own relationship with her, so I'll keep quiet no matter what...*

*Obviously I gave myself to him too easily. I have to tell him what happened last night, that it was a one night thing we should both forget.*

*I'd been mad at Kate for throwing our friendship away for a guy, but I was about to be the one to ruin it forever, because of what? Because I'm too horny? No, that can't happen.*

Then I heard the front door shut, and I listened, and I couldn't hear Kate any more.

For a while I didn't hear any movement whatsoever, and I thought maybe Luke had left too. Maybe he felt guilty about yesterday too, and realized it was wrong, and had just gone home...

Then I heard footsteps approaching. Slow, calm, measured.

My heart started racing.

"You in there?"

Luke was outside my door, and he wanted to finish what he'd started the previous night.

What *we'd* started the previous night.

I opened the door defensively, most of my body behind it, ready to slam it closed.

"Hey," I said.

"I thought you had a class," Luke said with a smirk on his face.

"I have a cold," I replied quickly, completely unconvincingly. "You shouldn't come in. I don't want you to catch it."

"How will I nurse you back to health then?" he asked smugly.

"Listen, um... forget about yesterday. Kate's my friend. I can't do that to her, so let's just pretend nothing ever happened so nobody gets hurt, alright?"

"Sure," he said, reaching out and taking my hand. "We'll forget about yesterday. Just like we'll forget about today."

It was like my hand wanted to be guided. It didn't even fight back.

I was soaking wet. I hadn't been able to get off the previous night, while I wasn't sleeping. I'd touched myself, but I'd felt too guilty to cum, so my pussy was still very much famished.

"You just want to fuck me," I whispered to him.

"I don't just want to," he whispered back. "I'm going to. Because you want me to."

He guided my hand to stroke him, and I didn't even notice when he let go, because I was doing it on my own.

I'd made out with someone about four months ago, but we'd stopped at petting. I hadn't had sex for more than half a year, so....yeah. I really wanted to fuck Luke.

But I knew I shouldn't. I knew he would just use me...but a part of me knew I'd love to get used. To just be fucked for pure lust. Why can men have casual hookups and us girls can't?

Fucking your flatmate's boyfriend is pretty far from a casual hookup, I guess.

So I tried to fight it. "I'm not just some slut you can play with."

He put his hand on my cheek and lightly caressed my face, before running his thumb over my lips.

"This is not a game for me, Amelia," he said, pushing his thumb into my mouth. "I'm risking everything here. Now, which one do you want me to fuck first, your wet little pussy or these pretty lips?'

I'd never had anyone talk to me like that before. Every guy I'd been with was super respectful and gentle with me. Hell, when Sam had tried to kiss me a few days ago, he hadn't been able to stop apologizing when I leaned away. He'd looked genuinely scared that I would think of him as a rapist or someone who'd tried to force himself on me.

And here was Luke, treating me like I was his fuck doll. Like I was some high-tech sex toy that could talk and respond, but was programmed to obey his every command.

Maybe this was why Kate was so loud with him.

I stayed silent, so he answered for me. "We'll start with your mouth, okay? Get on your knees, baby."

Luke pushed me down firmly but not forcefully, relying on my obedience instead of his strength. Once I was kneeling before him, he started stroking my hair.

I don't know how he was so sure he could control me. He just knew that he could do anything to me. And part of why he could was that confidence.

I'd be lying if I said I didn't like sucking cock, but I didn't just blow any guy who asked for it. It took time to build enough trust with someone for me to take their cock inside my mouth. Like, for me that was even more intimate than sex.

"Take it out," he commanded me, and I pulled down his pants. He was already erect, and his cock almost hit me in the face as it was freed. "Careful," he warned. "It's very stiff."

"I can see that."

I'd touched him the previous night, but I hadn't really worked out how big he was. It kinda just stopped me in my tracks, because I wasn't sure how I was going to handle it.

"Are you okay, princess?" he eventually asked me, looking down at me as I stared at him with awe.

"Yeah," I replied shyly. "You're just a little bit big."

He wasn't the biggest I'd ever seen - I had a short relationship with a guy once who was well-hung, but he was pretty awful in bed. Like he was a no-foreplay-just-ram-it-in-and-cum-in-2-minutes guy. Sex often hurt with him.

"If it makes you feel better," Luke said, "Kate couldn't take it either."

His little comment just made me so mad, I wanted to show him that I could do it.

"You'd be surprised what I can do that she can't," I said, grabbing his cock and leaning closer. I started gently licking its head, lubricating it before trying to take it inside my mouth.

After giving it a few licks, I began to kiss the head, letting more and more into my mouth with each kiss.

My entire body was throbbing.

As soon as I had the whole tip inside my mouth, he said "Did anyone ever tell you before that you look beautiful with a cock in your mouth?"

So fucking cheesy. So why did it make me smile?

Once I got a rhythm going, I went deeper and deeper. I can't deep-throat, but his penis was pretty close to hitting the back of my mouth. It actually felt somewhat uncomfortable, but I tried my best to impress him, and to show him that I could do it better than Kate.

He frequently complimented my efforts, calling me a good girl and assuring me that I was doing great. At that moment, I felt like it was my job to please him, that he was somehow above me. Like it was a privilege that I, out of every girl, got to take his cock inside my mouth.

My knees starting hurting too, but I didn't care.

After a while he said "Baby, you're doing so good that I'm gonna cum inside your mouth. But don't worry. I'm sure you'll be able to get me hard so I can destroy that tight little pussy of yours, too."

I nodded, increasing the tempo, focusing on his sensitive head rather than trying to take in the whole shaft.

A minute later, he exploded into my mouth. He came so much that I couldn't take it all and pulled away halfway through, so ended up covering my whole face with his seed.

I should have felt terrible. I just made my flatmate's boyfriend cum. With my mouth.

All over my face.

But I was just so turned on, I couldn't even feel bad.

After cumming into my mouth and all over my face, Luke just panted "You're so fucking sexy," pulled me up and - my face still covered in his cum - he just kissed me. And we just made out, our saliva and his cum mixing in our mouths as our tongues twisted and turned around each other, while my cum-covered face rubbed against his stubble, and it was just so dirty, yet so fucking sexy. Like no guy ever did something like that to me. They want their cum inside your mouth, but they are disgusted by the idea of tasting their own. He wasn't - I think he even enjoyed it in a twisted, narcissistic way.

That was our first kiss, too. I'd sucked this guy off before I'd ever kissed him. Our first kiss was while my face was covered in his cum.

God it was fucking hot.

After making out for a while, I pulled away and told him that I needed to text my friends, ask them to take notes on my next two classes as well.

"It's going to be a long day, isn't it?" he replied with a smile.

We took a quick shower, during which I managed to get him excited again. Partly because of our wet, naked bodies, partly because we continued to make out while getting clean.

By the time we were done, he was as hard as ever. I was so ready to fuck him. I couldn't have cared less about Kate in that moment, I just wanted him inside me.

But when we got back into my room, he pushed me onto the bed. "If you don't mind," he said, "I'm going to eat that tasty-looking pussy of yours first."

I told him that he didn't need to, that I was already wet, but the next second he was between my legs, eating me out...and this is when I realized why Kate was screaming so loudly all the time.

It took him less than five minutes to bring me to the edge of cumming. I started panting "You can stop, I'm gonna cum, you can stop, ahhh..."

I wanted him to put it inside me before I came, but he didn't. He wanted me to orgasm before he fucked me. To sort of tie up the game.

And I did. And god it was powerful; I was still shaking a minute later. And while I was panting, post-orgasm, he climbed between my legs and positioned his cock over my pussy.

"See," he said. "You don't get my cock that easily. You have to earn it."

I still wasn't sure whether it was going to hurt or not, because my last time with a cock his size hadn't exactly been a great experience.

"Let's see how eager this pussy is," he said, slowly inserting his throbbing hard-on inside me.

It actually slid in rather seamlessly. I'd never felt so stuffed down there before, but it didn't hurt. I just looked down and saw it disappear completely inside me.

"You're really fucking tight," he whispered.

"You're really fucking big," I moaned back.

It wasn't long before Luke was all the way inside me. I felt like I couldn't breathe, like I was completely stuffed. His huge cock was filling me up. It was too much, almost.

If I hadn't been on fire with arousal, I would have been in pain. But knowing that I was taking Luke's entire cock inside me, the cock that I'd thought about so many times when I got off, when I listened to him fucking Kate...it was such a thrill, I could barely feel the discomfort.

"Fuck me," I moaned. "Please..."

He didn't say anything in response. Like, I don't know what I expected: "Sure thing, Amelia, that sounds swell!"

But he just grinned, and - almost as slowly as he'd pushed his thick cock inside me - started slowly withdrawing.

Remember how I said I'd felt completely stuffed? Well, basically as soon as he started pulling out, I started to feel empty.

I'd had his cock inside me for all of five seconds, and already I was missing it. Yearning for it. I wanted it. I needed to feel him inside me again.

"Fuck me," I moaned once more, and his grin widened. I could feel his skin against mine. The abs I'd admired for the last few months were pressed up against my flat stomach; his chest was pressed against my tits, flattening me. He was on top of me, dominating me, owning me.

I was so fucking wet. Even though I'd just cum a few minutes ago, the feeling of his cock inside me...I'd never been so turned on in my life.

"Fuck me," I pleaded again, and my eyes widened with delight as he finally obliged.

You've got to realize, I wasn't normally like this. Like, if you passed me in the street, you might notice that I was a little curvy, but you wouldn't see me and think "Oh hey, there goes a busty slut who likes to get fucked really roughly."

And like, I *wasn't*.

I like rough sex, sure. Who doesn't? But I also liked gentle, loving sex. Sex where your partner stares into your eyes and tucks your hair behind your ears and tells you how beautiful you are.

I hadn't dated someone seriously for six or seven months, so yeah, I was a little more worked up than usual. But my ex had been a guy like Sam - a sweet, nice guy. And I don't mean a quote-unquote Nice Guy, I mean a really decent, loving guy. We'd only split up because he'd had to go back to Australia - it wasn't like I had cheated on him with a well-hung stud. I hadn't spent the relationship craving hardcore rough sex or anything like that.

I swear, I was just a nice, normal girl.

There was just something about Luke. He just *did something* to me.

And I loved it.

In response to my third plea for him to really fuck me, Luke started pounding into me. *Hard*. He was sort of on one elbow as he did, to give himself the leverage to ram his thick cock into me, fast and steady. His hands were running all over my body, his rough hands on my skin, occasionally grabbing my hips or my boobs. All the sensations started to blur together - the pain, the pleasure, his hands...

At first I'd been pushing back against him, grinding my hips into him, like I wanted even *more* of his huge rod inside my petite body. But as the pleasure started to overcome my brain, I just lay there. I'd heard someone describe girls who did this as "starfishing", but judging by the look on Luke's face, he didn't mind. He used me like a limp doll as I moaned and writhed with ecstacy.

It wasn't long until his eyes lost focus. "I'm gonna cum," he grunted, and I nodded. I wanted it - I wanted to feel him cum inside me.

I wanted him to use me as his sex doll. It was the hottest thing, I'd ever, ever done.

"Me too," I gasped, and my words were enough to make him shudder. After three fast, sharp thrusts, I felt his entire body tense up, and I could feel a warmness between my legs.

"Oh godddd..." I moaned, and there it was - my second orgasm of the morning. My toes curled and my eyes rolled back in my head as I twitched with pleasure, getting off at the feeling of his cum filling me.

After a few gasping, shuddering moments, Luke rolled off me. His grin was back, as his eyes scanned up and down my naked body. I should have felt bad, or at the very least self-conscious...but I didn't.

I'd seen Kate naked plenty of times, and I knew I had a better body than hers. I had the body of a porn star - she had the body of a girl next door. She was the kind of girl you'd take home to meet your parents.

I was the kind of girl you'd sneak out of dinner with the parents to get a back-stoop blowjob from.

"I never imagined this would happen when I swiped right on Kate," he chuckled, and I couldn't help but smile.

Horrible, I know. But the fact that we were cheating on Kate, cheating on my best friend...god, it turned me on in a way that I couldn't explain.

I loved it. Admitting that made me feel worse than I'd ever felt in my entire life. But it was true - fucking my best friend's boyfriend was the hottest thing I'd ever done, and I couldn't wait to do it again.

And I knew we *would* do it again. And again, and again, and again, and again...

Cheating on Kate

by BurroGirl18

Chapter 3

So yeah, the thing with Luke wasn't a one-off.

It was so intense, and I was overflowing with such a mix of different feelings. From lust to jealousy, just...everything. One second I'd feel regret and resentment, the next second I couldn't stop thinking about him and how good he made me feel. Then I'd get jealous of him and Kate...because even though we were having fun behind her back, they were still together, and they still fucked regularly, and whenever I overheard them it felt like I was being cheated on or something.

Like, one part of me felt super guilty for even doing this to Kate. Ever since it started, I was super nice to her, to make up for something that she doesn't even known about. Another part of me felt like I was being used, that I deserved better than being someone's secret lover. I deserved someone's full attention...but, of course, Luke had been filling a hole in my life.

Not like that. You know what I mean.

I was definitely being used by him, but I was also *using* him, so as long as I didn't fall for him...

Which, of course, I couldn't control.

Last time I mentioned Sam, Luke's friend. The guy Kate wanted me to hook up with.

Well, after our "disaster date", I kept in contact with him. As friends.

At first we both avoided *any* contact. I guess he felt embarrassed that he misread my signals and tried to kiss me, and I didn't want to feel like I was leading him on.

But after me and Luke hooked up, I messaged him. Since then, we'd been on friendly terms.

And then we started hanging out. I guess I sort of wanted to make Luke jealous as well? Sam and I were hanging out strictly platonically - we talked about it, and he basically agreed to being friendzoned.

It was sort of strategic, too; I wanted Kate to not suspect anything. So having her see me with Sam would make it less likely that I was a threat, or that I was going to go after her boyfriend.

That I was going after her boyfriend several times a week. And before. And simultaneously...

We were smart about it. It wasn't like that night on the couch - we never again fooled around while Kate was in the apartment. But that's the thing about giving your boyfriend a key and letting him always be over...

It gave us a lot of opportunities, you know?

I say we never did anything while Kate was around...and we didn't.

Not really.

I mean, sometimes when she left the room, he'd throw me a look. A really firm look. An "I want to be inside you look". A look that screamed "I want to bend you over and fuck you hard, right now" so loudly, I'm surprised Kate didn't hear it.

At first I just blushed, when he looked at me like that. I was so paranoid about my best friend finding out - it was bad enough that we were fooling around at all, but doing it in front of her?

Fuck. It made the whole thing even hotter.

That's what got me. At first, I'd just shake my head at him, and try to look unsuspicious. If Kate guessed what we were up to, I knew that'd be it. It'd be the end of a lifelong friendship.

But it was such a turn-on, it wasn't long before I started doing it back.

Just small stuff. "Fuck me" looks when she left the room, or slowly tracing one hand up my leg when I was on the couch and she wasn't looking in our direction.

We never, like, sneaked away to the bathroom so I could give him head.

But I'd be lying if I said I hadn't fantasized about that. More than once.

Anyway, Sam. I actually got to really like him as a friend. He's, like, super kind and super smart...I'm just not attracted to him.

He was basically the opposite of Luke.

So we bonded. I think it actually made Luke somewhat uncomfortable, but he tried to play it off like he was totally cool with it. He even joked a lot about me hooking up with his friend. I often teased him back that I might, cause he actually gave me his full attention, and I wasn't going to just be a side-chick for him.
