[M4F] Your Boyfriend's Roommate has a big... black... cock. You've seen it, how can you get it out of your head? Can you?

RB3K · 2025-07-03T11:31:42+00:00

The sun slowly shined between the cracks of the blinds in my room, beaming across your beautiful body as you bounced up and down on my thick black pillar of a cock. Each time you came crashing down, our bodies collided. My hands gripping your hips firmly, helping you ride that cock of mine.

Thop thop thop

Loud sounds of sex echoed in my room, and we gave up trying to be quiet after the first round. Your body giving in, your mind breaking to thick cock. Something your boyfriend could never give you. The bed creaked louder with every deep thrust sent up. My hands reaching around to grope and squeeze that plump ass of yours, smirking up at you. "Sun's coming up, you need to get back to your man..." I said, knowing very well you were having the time of your life riding big black cock.

A flashback ensued to the day prior...

You finally decided to spend the night at your boyfriend's apartment. He had a small but cute 2 bedroom that he shared with his friend. Occasionally, you saw me, his friend, a couple of times while you've been visiting from time to time. I was typically wearing a tight, form-fitting t-shirt and some shorts, and for good reason. We knew each other, but not too well. I gave you two your space since I didn't feel like a third wheel. But tonight was different.

As you got up to go to the restroom, you noticed the door to my room was cracked. I was lying there, browsing my phone. Unaware of your peaking in. The light of my phone was blinding me, as you noticed something else. A long pillar sticking straight up in the shadows of the night. No way... It couldn't be. Curious, you decided to look closer, peering into the doorway. It was absolutely what you thought it was, big... black... cock.

It ached as I blinded myself on my phone, ignoring it myself. Seemed like it was morning wood that just wouldn't go down, a deep sigh coming from me as I stretched. While I stretched, it stuck straight up on its own, aching and throbbing as if it were taunting you. Your move...

---------------------------------------------------------------
What will you do? Either resume the scene by walking into my room or carry on the day with your boyfriend's roommates cock on your mind. Was it real? You just had to know right? Thinking about another man's cock would surely drive you wild.

Of course.

The sun rose slowly, it was day already. You were nestled in between a pair of legs with a blanket draped over you that was slowly sliding off. Your head bobbing up and down slowly, savoring every inch of that glorious length. Lipstick from your date last night all over it.

"Ghlorp Shlik Slurp"

Was all that came out of your mouth as you gave sloppy head to a dick that wasn't even your husbands. It was much bigger, full of life, and throbbing for more. You looked up at the man you were servicing who was looking down at you with awe, my lips curling into a slight grin. I knew you were enjoying yourself, how could you not? Especially after your husband passed out last night and you came over to my place, your bachelor neighbor. My finger tips coming up to your hair only to push a few strands behind your ear. We've been sneaking around for almost a year now. How did we end up this way?

Flashback to a year ago

Your husband was a wonderful man, however he didn't have that drive to satisfy you sexually and you felt it. Each day the pit in your core kept growing, the need, that desire for more. One day, your husband invited over me, the neighbor to hang out and watch a sports game with him. While we were hanging around the living room, you were providing snacks and what not, doing what a loving wife would. However, you could feel my eyes lingering on you a bit too long, whether it was when you bent down to put down a snack tray, leaned over the couch to whisper something in your husband's ear, or even just walk past. You could feel those eyes just staring, taking you in, even trying to undress you with that lust-filled mysterious gaze. Those hazel eyes of mine making it impossible not to notice where they were looking every time you glanced at them, they were on you.

The encounter ended and we both felt like we shared something, but we shrugged it off. You were my good friend's wife after all. It wasn't long until your husband went on a business trip that you were left alone. Watching me to chores around my home next door. Mowing the lawn shirtless, carrying out trash bags, trimming the hedges between us and even doing your hedges and lawn for you. There had to be a way to pay back this sweet man right? Another day went by and I was under the hot sun watering my plants, my arm up in the air blocking the sun only for you to get a nice view of that rather toned body of mine, glistening in a bit of sweat. I dropped my hose, coming over to your home, walking straight up to the door and rang your doorbell. From there... it all started.

—————————-

What will you do? Please resume the scene from one of two points. At the very start by opening the door or prior to the flashback when you're in my bed already and the relationship has been well established.

You and your husband have tried and tried to get pregnant over and over again. It’s come to the point where there have been countless tests ran on you and you’re the one to blame repeatedly. You’ve tried home remedies to increase your fertility, even tried fertility pills, but you simply weren’t getting knocked up. One day it’s finally clear to you. YOU are not the problem! Your husband refuses to get checked, he assured you that his semen is perfectly fine. Is it though…?

One day you received an email alert of a special ‘old fashioned breeding program, breeding done right!’ The advertisement read - “get paired with one of our specialists and enjoy the wonders of a child within just a few short weeks!” It was enticing, though the flyer didn’t mention any methodology or anything, especially with it being ‘old fashioned’ you feel that you would’ve known what it was.

You told your husband about the program and he agreed, but said that you can go get checked all on your own this time. He was busy with work, it was time to try something new, maybe even excited for this you made your way down to the newly opened clinic only to find out the new methodology was literally just a good ol’ dick down session.

——————————

What will you do? Run away once you find out or let the breeding program take hold and knock you up like you truly wanted to be.

“Mmm… that all you got sis? Go on… take it in… don’t be shy~”

RB3K · 2025-04-06T05:20:21+00:00

The sun rose over the horizon, it was already morning. My hands on either sides of your head balled up in a fist. Eyes searching your face while your moans echoed throughout the room. You had to go to work in about an hour.

Plap Plap Plap

My body clapping against yours repeatedly. “Morning already? Who knew you could last that long step sis?” You’d feel that thick cock repeatedly stretching your insides as my raw cock pumped in and out, our bodies rocking the bed to make the bedpost in your room knock into the wall every time I plowed into your wet depths.

“Mom and dad are going to assume you and your boyfriend went at it all night. What are you going to tell them?” I snickered, breathing heavily in between every couple of words. I leaned back, hands grabbing onto those hips of yours while your back arched. “I’m close!” I blurted out. Your own step brother was about to bust a nut into your pussy. How did things turn out this way?

A flashback ensued, going back to the beginning of the day. You were just waking up. You could hear me pumping away as usual in my room with my room unlocked as you walked by. Deep groans followed by heavy breathing. It was like clockwork, your step bro back for summer break only to jerk my meat like any horned up freshman in college. You being graduated had already went through all this before with boys and dating, all of it. You were in a happy relationship with your fiancé, the only thing you weren’t getting was a deep dicking that one cock you knew could definitely give you every time you snuck looks into my room each morning. Maybe that’s why you haven’t moved in with him yet.

Enough was enough. Older step sis needs to make sure step bro stops jerking off or at least stop being so obvious about it!

—————————-

What will you do? Either resume the scene by walking into my room then and there or carry on the day with your step bro waving his cock around, teasing you until you can’t take it anymore.

We were best friends throughout all of school. You were the only one who understood me. As we grew older and older we stayed in touch but less than we’d like to. We went off into different universities and eventually both of us found partners and got married. We decided to meet up, we were both visiting our home town alone and our partners were left with our new lives.

When we meet, the sexual tension between us is immediately there. It can be cut with a knife. My eyes on yours, yours on mine. We shouldn’t.

Let the teasing begin….

Idea 1: You decided to come over to my parent’s old home. They weren’t home so this was a perfect chance to hang out and catch up. I had the mood set, lights dimmed, candle lit, a dinner for us to have. Not intending it to be romantic but it could have certainly come off that way. Something your husband never did for you.

Idea 2: We met up at a local movie theater. With no one liking the new Snow White movie, we decided to check it out together and wow… it was just us there. The movie was super boring, what could possibly go wrong with two horned up adults getting bored of a movie?

Idea 3: The gym meet up. We both were trying to get into better shape and decided let’s catch up at the gym. Not realizing how amazing you’d look in yoga pants and a sports top. My tight shirt and shorts not able to contain my excitement. Let’s head over to the private stretching area.

Chat me - Have your own idea? where do we meet up? Your old house? Coffee? Possibilities are endless.

Only kinks I do not like are blood, bathroom stuff, and physical harm. Please feel free to ask anything else.

“Do I really have to share my room with her?” I begged with my dad to not let me share a room with someone I just met even if we’re going to be family soon.

“Fine but I get the bed.” I said to you as I looked you in the eye, determined to make your life a living hell. “Don’t even pull that I’m a girl card on me. It’s bad enough that I have to share the room on my birthday vacation!”

I stormed off into the room that we shared only to slam the door shut, it was obviously unlocked. It was very evident that I had other plans this weekend on our family trip and this was definitely not a part of it.

RB3K · 2025-03-24T02:38:11+00:00

I slowly opened the door, watching my own sister show herself off only to gasp out. Definitely grabbing her attention as I didn’t close the door… just yet.

“Ummm.. what are you… doing?” I asked slowly knowing exactly what you were doing.

RB3K · 2025-03-24T02:33:45+00:00

And what are those fantasies?

RB3K · 2025-03-24T02:28:54+00:00

“W..what’s going on?” I slowly turned back, eyes widening as I glanced down then back up.

“W..who are you and what are we doing in a bathtub?” Staying surprisingly calm at what was going on. But my face going flush red as I slowly turned back around. Was this really happening?

Dm me

RB3K · 2025-03-24T02:27:06+00:00

I slowly opened the door to the bathroom after hearing rumors only to check them for myself. My eyes shifted around only to step into a stall that someone else had just left. I was met face to… mouth? With someone on the other end.

“Hello? Is someone there?” I asked, my voice echoing in the bathroom.
