Cucked By Dungeon Master Ch 04

------KRISTEN------

I'll admit I fucked up. And now that my multiple earth-shattering orgasms were just a tickle and hum ligering in my body, I felt the weight of guilt in my heart return. I walked, shamefully, from the bathroom after cleaning Mark's cum out of me to return to Ben's bedroom. Despite the guilt, I'd be lying if I said there wasn't a part of me that wanted to head right back into that living room.

I had made enough dog-shit, selfish, decisions tonight. I would return to Ben's room and get my lying out of the way. The least I could do is get Ben to cum after what I had done.

I cracked the door and found Ben laying exactly where I left him, his cock still hard. Normally this sight would excite me, but between the guilt and the nigh-paranormal fucking I had just received, I felt only dread. I closed the door and approached the bed.

Trying to sound normal and chipper I said, "Hey baby, you awake?"

"I want to cum so fucking bad, what happened!?" He asked sounding excited. His tone made me feel a little more secure that he wasn't skeptic about what happened.

I climbed on top of him, hovering my tits above his face. I tried to come up with a bullshit story for him on the fly.

"It was so easy baby. I just went out there and started touching my boobs, pushing them together. He was timid at first, but when I said you were asleep he came running over to me." I said, thinking that sounded mostly realistic.

"Fuck baby, did he touch you?" He asked, breathing heavy.

"Oh my god yes. It took no convincing, he felt me over my clothes but that wasn't enough for him. He put his hands under my shirt and took my tits out for me. He was so aggressive baby." I said, testing his limits.

"Did you like it? The way he touched you?" He asked.

"Fuck yes" I moaned before I could think to obfuscate the truth, I rolled with it, "He wanted me so fucking bad, it was so hot. He would have done much more if I didn't stop him"

Ben moaned beneath me, "What did he try?"

"Well. He got hard. I mean he was only wearing boxers so it's hard not to notice, and it was... I mean it was REALLY hard not to notice." I teased.

"He's... Big?" Ben asked, sounding timid but clearly VERY aroused.

"Do you want to know that?" I asked, genuinely puzzled.

"Yes" he said, and I replied honestly - Yes.

"Did you want to touch it?" He questioned, I could feel his body squirming beneath me.

"God baby his hands felt so good. They way he hungrily groped my tits was incredible, and knowing you were in here patiently waiting for me to be done was so fucking hot. I was super turned on, so... yeah I wanted to. But I was a good girl." I lied. I was anything but a good girl tonight, at least as far as Ben would be concerned, "Do you wish I did?"

"Yes!" Ben said immediately, catching me completely off guard. Was this just fantasy? Not what he really wanted? Or was he just so fucking turned on that he would say anything?

"Maybe I will next time. I'll stroke his big cock while he touches my tits, do you want that baby?"

"I'm going to fucking cum!" He said, squirming heavily beneath me. Quickly I lined myself up and slammed my pussy down on him. I figured Ben deserved to cum inside too, I'd already need to get a morning after pill so why not take all the loads I can. He immediately unloaded inside of me, and I pulled myself off of him shortly after. I gave Ben a kiss, ran to the bathroom for the second time tonight to remove cum from me and ran back to the bedroom.

Ben was lying in his normal position on the bed now, I hopped up and cuddled next to him.

"That was so fucking hot baby." I said, "I love how worked up this gets you."

"I thought I heard you say, 'fucking' something while you were out there, what was that?" He asked.

I was shocked at the sharp change of direction, and tried to rack my brain for what what he might have heard. I wasn't exactly being quiet out there, so I just made up a quick, related, lie.

"He tried to suck my nipple, I told him to 'fucking stop'" I said, leaning over and kissing him on the cheek playfully, "Maybe next time."

Ben just laughed, and he fell asleep pretty quickly after that. I stayed up awhile longer, feeling two emotions. Guilt for what I had done, laying in my boyfriends arms being lovingly cuddled. And absolute desire of it's rawest form, my body was vibrating in anticipation of the next time I might get Mark alone.

------BEN-------

When I woke up, it took a few seconds for the events of last night to come back to me. We definitely got a bit too drunk and made some decisions in that horny state that I wouldn't have made sober. But I was suprised to find I was more turned on by it than overwhelmingly jealous.

At the end of the day, although Kristen pulled a lot of what I said out of me, I felt like the driving factor in what had happened. I had told her to go into the living room, I helped set the rules for what she would do. She even double checked with me to make sure we were understood with how far it would go. And I completely trusted that nothing else happened. I mean, if she did cheat why on Earth would she admit that she saw his - big - cock in his boxers? Or that she wanted to touch it?

A picture flashed in my mind of Kristen stroking his cock, while he played with her tits on the couch. Immediately I was hard as fuck. Briefly I revelled in how insanely fast this fetish had hit me. The pangs of angst and longing were a fucking drug and I needed a fix. I loved my daydream and fantasies, but the rush of her ACTUALLY going out there last night was INSANE, such an adrenaline rush not knowing what was happening for the - admittedly long - time she was out there.

I rolled over and woke up Kristen by playing with her tits again, it wasn't long before she turned over to me with a lusty smile.

We played again that morning. I had her replay last night for me again, she was light on the details but it was enough for me. We even talked a little bit about what we should do to continue this fantasy for us. We settled on some teasing suggestive texts and photos while she wasn't with me. Our DnD sessions were on Saturdays and she would usually go back to her place Sunday nights to get ready for work the next day, which left us plenty of time away from each other to play.

First thing was first though. We needed to leave the bedroom, and Mark might still be out there. For the first time in forever, I felt nervous about leaving my bedroom. Facing the man who groped my girlfriend, even if he thought I didn't know about it it would be weird.

Kristen also seemed nervous, but we both took deep breaths and exited into the kitchen.

Mark was indeed still there, again he was gathering his DnD stuff to take home.

My heart was pumping when I saw him and my voice caught in my throat. Suddenly looking at Mark in a completely different way. This, apparently, well-endowed and aggressive man who just hours ago had his hands on my girlfriends tits gave us both his usual friendly smile.

"Morning guys! Sorry I slept in a bit again, I'm just heading out now."

Both Kristen and I were a little quiet, just trying to get through this conversation more than anything. He got his things together and said, "Thanks again for your hospitality" looking more at Kristen than me before we said our goodbyes and he left the house.

It's hard to explain the feeling of standing in front of a man who thinks your girlfriend is cheating on you pretending like nothing is happening. All three of us had little secrets we were keeping from each other, with the exception of Kristen and I. At least, that's what I thought at the time.

Once Mark left Kristen and I did our usual morning routine. We got breakfast, hung out and watched some TV and she headed out a little earlier than she normally did. She said she had to go shopping before the work week started and that sounded understandable to me. We kissed, and talked a little more about her sending me some suggestive texts to keep this fantasy rolling and have us both all turned on during the week, before saying goodbye.

I ran to the bedroom and immediately started masturbating to what Kristen told me happened last night. Filling the spaces between her words with thoughts about what COULD have happened. As I felt more comfortable with my relationship, my kink, and all that has happened, my fantasies got darker. I imagined her gagging on his cock, titfucking him, fucking him even. I had masturbated and cum once already when I got a text message from Kristen.

"Mark's gonna come over baby, but we're just gonna talk -winky face-"

Seems the teasing began sooner than I expected. I stroked my cock and responded.

------KRISTEN------

Technically I DID need to go shopping, but not for food or toiletries or other general home goods. I had taken two loads inside of me last night after years of being very careful with Ben and various FWB before him. I needed a morning after pill something serious. I had used them in the past and while I didn't like the emotional rollercoaster they sent me on, they had always been effective.

I used the bathroom at Ben's house before I left, and that's when I noticed I had a new text. From Mark.

"We should talk, mind if I come over?" it read.

Yeah, talk, I'm sureeeee.

The part of me that hated Mark and his pompous douchebaggery was still there, though smaller now. He was a dick, don't get me wrong, and he definitely carried himself like he could have me whenever he wanted, like he was King-badass Mr. Steal yo Girl. But fuck man, was he wrong? I had NEVER felt so sexually fulfilled as I did last night. He knew exactly what my body craved and exactly what to do. I felt myself getting wet with my phone in my hand as I finished up in the bathroom. Fuck it.

I texted Mark my address and tried to retain some of my dignity, "JUST TALKING" I wrote.

Ben and I kissed at the door and I promised I would play into his fantasy with some texts throughout the week. He wanted me to tease him and send pics or roleplay what I wanted to do with Mark etc. If only he knew.

I had to drive in the opposite direction of my house to go to the pharmacy to get the pill. I threw the package in my glove compartment, and drove home thinking about what a horrible girlfriend I was. Sure Ben enjoyed some of it, the teasing, the talking, the suggestions, even what he believed was mild play last night.

I had some kind of excuse, however flimsy, the previous times. "I didn't exit the bedroom with intent to fuck Mark, I promise baby!" or "I was turned on and he took advantage of me in the bathroom, I promise baby!"

But now? Even in the best possible interpretation of what I was doing from Ben's perspective would be fucked up. Inviting the guy who just played with my tits to my apartment to 'talk' without Ben's approval? Like what the fuck was I doing?

In some sick way, I thought I could retroactively make everything I was doing okay if I could get Ben to the point where he wants me to fuck Mark. Obviously I was doing all sorts of mental gymnastics to justify my actions, but when the gold medal is a cock that sends you to the fucking astral plane it's hard not to. A sick thought crossed my mind and I texted Ben.

"On my way home! Mark's gonna come over baby, but we're just gonna talk -winky face-"

He wanted me to tease him while I was gone right? So Ben thought it was a fantasy when it was actually happening, at least I told him right? If I got caught, maybe it was just a misunderstanding? The pit in my stomach knew this was hollow reasoning.

"Oh shit baby. Tell me how it goes! Maybe send a pic if you get a chance" He replied, returning my winky face.

I pulled into my apartment complex, and saw Mark already standing outside of my apartment leaning against the door. I gathered my nerves and walked up to the door.

"Hey gorgeous, still love that outfit, you actually live really close by to mine." He said looking me up and down. I didn't bring a change of clothes to Ben's so I was still dressed in the outfit I wore to DnD.

"Thanks" I replied, trying not to give in to the quivering way his words made me feel, and rushing to put my key in the door and open it. I walked inside first and he followed, closing the door behind us.

"Your cuck is fucking oblivious huh? There's no way he didn't hear SOMETHING last night but he acted like everything was cool." He said once we were both inside, still standing right by the door.

"Cuck?" I asked, "What the hell is a cuck?"

"What? Ben! You don't know what a cuck is?" He asked, seeming genuinely befuddled.

I didn't. I liked the things I liked, sexually, but this kind of thing had never come up on my radar.

I shook my head.

"Holy shit. Cuck's are guys who like their girlfriends or wives or whatever messing around with other men. Usually..." He said moving closer to me and placing a hand under my chin, "Men who fuck them better than they can."

My body shuddered at the thought. Fuck, he WAS right. Ben definitely enjoyed the thought of me messing around with Mark at least, and as much as I hated to admit it, Mark DID fuck me better.

"You said something like 'He wanted me to think he was asleep and I could only play with your tits' or something like that, right? So he sent you out there to me under those instructions?" He asked, and I nodded.

"And what did you tell him we did?" He asked

"That you played with my tits, and got hard, and wanted me to do more but I said no." I said flatly. Goddamnit I was in a fucking trance with this guy again. I shook myself and removed his hand from my chin.

"Look Mark, he may be into the idea but he doesn't know half of what we've done. I feel like fucking shit about it. He may eventually want it but it's not like he's begging me fuck you, I've cheated, TWICE, and I hate it." I blurted out, finally speaking out loud the emotions that had building up inside me.

"Oh you hate it huh?" he said, stepping closer and placing a hand on my hip, and pulling my body into his.

"So I should just leave? Let you be a good girlfriend to your cuck? And I should just dutifully wait until Ben is ready?" He asked, a soft smile on his face.

This was my chance to say the right thing, for the first time in the last week or so to actually prioritize my relationship over Mark's cock. Staring Mark in the eye, our bodies pressed together, I spoke my truth.

"No."

"Good girl." He said, running his hand from my hip to between my legs, I moaned slightly when he made contact.

"It's just us here, and we have plenty of time, we can be ourselves, you know what I mean?" He said as he started rubbing the outside of my pussy.

My legs were shuddering in anticipation. He was right, again. It was just us, sure I told Ben Mark was coming over to talk. But that was just fantasy as far as he was concerned. I could spin it however I wanted. And fuck, maybe if I had a moment to just let loose I could get this out of my system. I was here already. Might as well make the most of it. I'd like to say I struggled with the decision, but I didn't.

"Yes Daddy." I said sweetly.

"Then get to work, princess." He commanded and I obeyed.

Immediately I fell to my knees in the entryway of my apartment and started working Mark's shorts off. He stepped out of his shorts and underwear as his heavy cock bobbed in front of me like a lure for sluts. I took the bait.

It was just Mark and I. No prying eyes or ears, and plenty of time. I could actually take things slow.

I didn't.

I grabbed behind his thighs and pulled my head as far down on his cock as I could. With Mark, I wasn't a sweet doting girlfriend, I was a cumslut yearning to be filled, tossed around, used. Getting his tip in my mouth isn't easy with how girthy he is, but I was hungry for it and I quickly worked him inside of me. When I reached as far as I felt I could go I pulled on his thighs, pulling it deeper inside my mouth and causing me to gag and rip my mouth from him.

A large glob of saliva trailed from my mouth, connecting his cock and my lips like a perverted version of the spaghetti scene from Lady and the Tramp. As I caught my breath the spit fell to my breasts and my shirt.

"Up" He commanded, and I was on my feet in an instant.

Quickly and aggresively he tore my clothes off of me, pulling my top over my head and my skirt down off my body - discarding both by the front door. As he worked my skirt off I unclasped my bra and unceremoniously tossed in the pile.

"While I am here. No clothes. Understood?" He said.

"Yes Sir. No clothes when Daddy is here." I replied. All traces of 'Normal well-adjusted citizen' Kristen had disappeared. Once again, I was completely under his spell. Gotta work on those saving throws.

He pushed my tits together with both hands, pinching the nipples for a moment before releasing them and continuing to massage them.

"I can be good, see? I'll just play with your tits since that's all Ben wants." He teased. What a fuckin' dick. I fully give myself to him, follow his instructions, fall under his sex trance and he pulls back. The ebb and flow fucking killed me. I groaned loudly, frustrated.

"Oh? Do you want more than that? Against Ben's wishes?" He knew the fucking answer.

I nodded meekly.

In a flash his hands left my tits and one slammed into my throat, pushing my back against the wall with a loud THUD.

"Say it out loud. Ben can't hear you." He demanded.

He squeezed my throat and with his free hand slapped my breast - hard. And Ho-lee-shit folks lemme tell you I didn't know I was into that but GOD DAMN. My legs almost buckled. Maybe the straight guys reading this won't understand but the ladies will. A powerful man putting you in your place, doing what he wants with your body, reminding you of his strength. It's a primal sort of lust with a touch of fear for seasoning.

I was in shock, the sudden flash of aggression, the pure power of his thick arms and strong hands. My body flooded with fear and my pussy just FLOODED

My mind broke in that moment, whatever part of me was still hanging on to the idea of being Kristen - Ben's girlfriend - taking part in a fantasy for my boyfriend and going a little further than I should vanished. I was a slut, a tool. Mark was my God, who would bestow upon me intense pleasure in exchange for my complete submission.

"It doesn't matter what Ben wants" I croaked, feeling a weight lift from my chest. Finally speaking the truth, "Fuck me"

Another slap came fast and hard, I squealed in both pain and pleasure as his heavy hand made contact with my tits.

"Good girl." He pulled my head from the wall by my throat and started pushing me backwards towards the living room. He flipped me around with what felt like no effort and bent me over the arm of the couch. I fell forward, hard, and caught myself by placing my hands on the cushion to keep my face from slamming into the couch. Immediately came a barrage of spanks, I felt my ass jiggle and tense as the pain came and my body shuddered with anticipation.

He rubbed his long shaft along my ass before I felt it line up with me and he thrust inside fast and hard. This was different than last time. Last night in Ben's house he teased me, poked and proded until I was so turned on I placed him inside of me willingly. Today, he was taking it. I was a willing slut and he knew it. I was his good girl, his princess, to do with as he pleased.

"FUCK!" I yelled as he slammed into me.

His body fell over mine until I could feel his hard abs and chest on my back and shoulders. One large arm looped around my neck until he had me in a chokehold. He squeezed and began his relentless thrusting.

When I tell you my brain fucking MELTED. I felt like a trapped animal. Expertly captured by a predator who was tearing into me. For some reason I became overwhelmed with emotion. I felt like this was my purpose, finally fulfilled.
