It was meant to be a threesome, but I accidentally cucked my fiancé.

Last year for our anniversary, my fiancé and I had our first threesome. This brought to reality a fantasy he had shared with me, and with some collaboration we agreed on some ground rules, and who our 3rd would be. He wanted a woman, I didn't. We compromised and brought in another guy. We spent weeks talking about our rules, expectations, hopes, and of course, who the 3rd should be.

After a lot of deliberation, we decided that we would bring in his room mate, As it was his senior year, there would be no awkwardness lingering between them, and he was reasonably attractive. My fiancé would be in charge of the planning.

A Friday night a couple weeks later. My fiancé came to pick me up from my apartment. As we drove to his place we reiterated the ground rules. He didn't want me to kiss him. We weren't going to let him cum inside of me. And either of us could end it if we felt like it was too much to handle. I had no idea all 3 of those rules would end up broken.

We walk in sit together on the couch, we all have a beer in hand and start to talk. It's almost funny how casual the conversation is, despite all of us knowing why we are there. My fiance broke the ice, he pulled me in for a kiss. I was nervous, but the beer was helping. My heart was beating out of my chest. As we kiss, I reach my hand out for his room mate, I find his hand and move it to my lap, I return my hand to his crotch and start to rub him through his jeans. He slowly starts moving his hand up my thigh, pushing my skirt up. My fiancé pulls my shirt up and unhooks my bra. It's flung across the room. As if on a timer, both these men latch themselves to my breasts. I have to admit the attention is sexy.

I move my hand to his pants and try to work on the buckle. The angle is awkward and I can't seem to unlatch it. He stands up, unbuckles and slides his pants fully down. My fiancé is starting to rub my pussy through my panties as he nibbles on my nipple. I'm shocked at the view in front of me. His cock is average in length, but he is thick. He's got to be twice as thick as my fiancé. Almost acting on instinct I reach out and grab him, slowly stroking with one hand. He is standing in front of me, we lock eyes. He knows I'm shocked, the look on his face tells me this isn't the first time he's made this impression on a woman.

Suddenly I feel my fiancé pull me back. He kisses me roughly while trying to pull of my skirt. He is moving fast. I think he might be jealous of my reaction to the larger cock in the room. He pushes me back on the couch, I look up at him and he is rolling a condom onto himself. He quickly pushes himself into me and starts thrusting into me, hard and fast. He isn't talking, I think he is still mad about my reaction. I am spurred on by his jealousy, for some reason it's only making me want the other guy more. I reach out for his cock, dangling above me. He quickly kneels on the couch next to me and lets his cock rest on my lips. His fingers are playing with my nipples and I can't help but to start to give him little kisses on his hard cock head, in between kisses I move to licking him, he starts to thrust his hips so I'm licking and kissing up and down his shaft. He's letting out these soft little groans that are making me want more. I open my mouth and he slides in, I envelope his cock with my tongue, he starts to thrust and push himself further and further into my mouth. His balls hitting my face with every thrust.

Suddenly I feel my fiancé start to jerk, and groan. The unmistakable signs that he has already came. He pulls out and starts to take off the condom. He looks at me, I make eye contact with him, while his room mate is fully in my throat. He looks hurt, he knows I've never given an enthusiastic blowjob like this to him. "My turn, let me get one of those condoms." the room mate says while pulling out of my mouth. "Oh, uh. I only brought the one." "No worries!" he says as he runs down the hall way to his room. My fiance looks at me, and says "Babe. Let's go. I don't think I can do this" I'm really frustrated, "What?!" I say in an angry whisper. "I don't want to see him fuck you, please babe."

I'm just getting more frustrated, and honestly I was disappointed I wanted to feel him inside of me. "Babe, just wait." I tell him. "You never know, you might like it, plus you'll get hard again and can go a second round with us! If you still want to stop we can, I promise." I know it's a lie as I'm saying it. I realize how badly I need to be fucked. He comes back into the living room, my fiancé is sitting in the chair sulking. The room mate opens his hand and he has a whole roll of condoms. I quickly grab one. I can't open it up fast enough. I roll it onto his cock, he is rock hard. I swear I can feel him throbbing. I lay back on the couch, legs spread wide. He kneels between my legs and positions himself at my now soaking wet pussy.

He pushes into me, but he is thick. It takes a while for me to adjust. Before he is even half way in, I can't contain myself "Oh, holy shit." I blurt out. "You're so big." I instinctively cover my mouth, I know he's going to be mad I'm saying this about another man. My fiancé stands up and says "Babe, we gotta go." I can barely hear him. My ears are ringing, I can feel electricity running through my muscles. The room mate doesn't stop, he actually seems to be going faster. He looks at my fiancé and says "You're not gonna blue ball me, are you bro?" I start to shake as an orgasm wracks through my body. I am cumming on his cock, while my Fiancé starts to literally beg me to leave with him "Babe, please stop!" I hear him, but I can't respond (oops, there goes rule 1). My body feels like I am no longer in control of myself. My legs wrap around him, pushing him deeper inside of me, and my nails are clawing down his back and he takes deliberate thrusts to make himself fully inside of me. He leans in and whispers in my ear " Am I bigger than him?" I weakly respond with a "yes" between moans. "Yes, what?" he says firmly "Yes, you're bigger than him." I respond honestly.

My fiancé is yelling now, begging him to stop. "Bro just shut up, let her enjoy herself for once." He leans down and starts to kiss my neck. I keep my eyes closed so I don't have to see my fiancé. I feel guilty, but it feels too good to stop. He grabs me and picks me up, he sits down on the couch and holds me while I ease myself down onto him. He is stretching me in a way I am definitely not used to. His hands are on my ass as he guides me up and down on his cock. Suddenly we're kissing (oops, rule 2). Something clicks in my brain and I can't help myself. I start bucking wildly on him, I want to feel him deep inside of me. I putting everything I have into this, I reach back and start to rub his balls as I grind on him. He is kissing my neck. I feel the familiar feeling in my muscles, as I'm brought to my 2nd orgasm of the night on his cock. "Fuck baby, has he ever made you cum twice in one night?" trying to catch my breath, I muster a "no". He gives my ass a spank, and says "I'm going to make it 3." He lifts me off of him again. and moves me to my knees on the couch. He positions him self behind me, his hard cock ready to take me from behind.

I stop him, I turn around and pull the condom off, tossing it to the floor. I get back on my knees, and he quickly slides inside of me. It feels as good as I imagined it would. I can feel his balls slapping against me, he grabs my pony tail and pulls my head back. He kisses me one last time and I feel his cock start to shoot his seed deep inside of me. It felt like it was never ending, and finally. He collapses next to me, both of us sweaty and exhausted. As I'm sitting there I can see my fiance, clearly conflicted. On one hand, I broke all of the rules, but I can see his cock in his hand and he is slowly stroking himself. I stand up and walk over to him. I lean down and give him a kiss. He starts to stroke himself faster. I reach down and stop his hand. I whisper into his ear "Thank you baby" and I get on my knees in front of him and easily fit him in my mouth, I can feel him in the back of my throat, i bob up and down on him, and sure enough within a minute he is cumming in my mouth. We get dressed and drive home in silence.
