You and my girlfriend have been practically inseparable since summer camp in the seventh grade. All through high school you took the same classes, worked the same after school job at the cinema, and then you even shared a dorm the first two years of university. It would have been three if she hadn't moved in with me, but after a few tears, you found it in your heart to forgive me (even if you still jokingly bring up how I stole your bestie away from you).

Suffice it to say, it's no surprise that you hang out with us all the time. I've never exactly minded. I mean, we get along well enough, and if nothing else it's always incredibly easy to tease and wind you up to add some spice an otherwise boring afternoon. Sure, Katie might scold me a bit after, but I've seen her do it, too. You've just got one of those adorable, pouty faces that's too much fun to fluster. Honestly, it feels like you're asking for it sometimes.

Yeah, you're the eternal third wheel, but no one seems too bothered by the arrangement. After all, the more the merrier for most things. Our movie nights are the stuff of legends, and your love of nerdy shit has sparked a cultural renaissance in my apartment. But as far as the more intimate things go, Katie and I have never really shied away from indulging ourselves just because you're around. PDA is par for the course when we're out and about, and sharing that dorm freshman year, you had to put your earplugs to the test whenever I slept over (which was pretty much always).

It's no big surprise that you've heard some downright decadent dirty talk when we're out together. You've soldiered on through your fair share of us feeling one another up with promises of what's to come once we're alone. Today's more of the same for the most part, but Katie's apologetic look throws a wrench into the usual script.

"I'm sorry, babe," she assures me with a gentle, soothing pat on the arm. "You know how my mom is, I didn't even know she made plans for us until she sprung them on me."

"Come on," I urge, winding a possessive arm around her tiny waist, urging her in closer. "You don't even have time for a quickie? It's not like she's out front yet."

Playfully swatting my shoulder, she effortlessly turns my lusty embrace into a sweet, squishy hug, even tiptoeing up to rest her cheek against mine. "But she will be soon, and you know she'll go weapons-grade-guilt-trip if I make her wait even five minutes."

"Five's all I need if you break out that new lingerie again," I interrupt with a lecherous arch of a brow. I'd gladly indulge in some self deprecation if it led to self satisfaction.

"Oh stop," she snorts, finally breaking free from my embrace. "You can keep it in your pants until I'm back tonight, if I survive. Or go jerk off or something," Katie huffs. "Either way, just behave."

"I'm always on my best behavior around you," I hum glibly, tugging her back in once more. But this time it's more sweet than salacious, greedily stealing another hug from her before she descends into the depths of an entire afternoon with Dear Mother. We all know she's going to need it. "Love you. Good luck with the Queen Narcissist, give her my regards." Pecking her cheek, I crack a wry grin to undo all my efforts to amend my behavior. "Just know I'm insanely horny right now and you're absolutely missing out at least two and a half orgasms you'll never get back."

With an airy sigh, she just shakes her head as she peels herself away from me to grab her bag and head for the door.

"Keep him out of trouble, okay?" she laughs, casting her glance back across her shoulder toward you.

Somehow I'd forgotten you were even still here. But then, so was the couch, and I rarely thought much about that either until I needed to lay on it. For a moment, I wonder why you aren't trying to tag along with Katie, but then I remember you're even more terrified of her mom than she is.

As the door clicks shut, I turn to you with a wide grin, my mischievous eyes chasing down your shy gaze. "So, how are you keeping me out of trouble? I mean, I am a bit of a handful."

Hooking up with my girlfriend's best friend, the perennial classic. Several ways to play it. Are you eager to get a little something for yourself, after seeing what Katie's been getting all this time? Indifferent to the idea, but you'll do anything to treat that separation anxiety from your bestie? Reluctant, but too shy to say no? Maybe this is just a roundabout way for you to get closer to Katie? Hit me with your take.

Some of the kinks I'm interested in for this scene include cheating, casual sex, barebacking, size difference, risky sex, semi-public, lingerie, and creampies.

Limits are non-con, abuse, bodily fluids that aren’t saliva or sexual, rimming, and darker themes. I'm also not into guys, even if you're playing female characters. Sorry!

Hit me with a message to hammer out the details, or feel free to jump in where the prompt left off. DMs, chat, roll with whichever, just send me more than a one liner.

I dunno about this one, it feels like a bit of a mess. I threw it together just to get the idea written down, but it still feels like it's missing something. Probably more typo-riddled than I'd like, too, since I jammed it out right before bed. Caught more than one incorrect 'you's that should have been 'she's already since I'm so used to not having to refer to multiple characters. I don't expect anyone to do any free editing for me, but if you happen to see something that sticks out, I'll fix it in my next pass.

I could certainly work some descriptions in there, but it's running a bit long as it is, so I dunno where I'd best squeeze them in, or what I might trim to make it work. Starting with the interaction and then going into the 'hey here's some third wheel lore' also crossed my mind, but I don't know if that really fixes my problems.

Either way, I'll gladly accept some notes on how to make this more enticing to someone who's not sold on the premise alone (because it feels like that's all there really is here). I'm not married to the title either, but I love a good pun so I just rolled with it.
