No explanation necessary. Emma pulls her inside.

The hum of the plane's engine suddenly turns to a piercing white noise in your ears as you start to register what's happening. You're going to be arrested, probably put on a sex offender registry, probably barred from flying. Everything is crashing down around you. You're in a daze and can't even begin to blather some kind of excuse. The stewardess looks between you and Emma, not sure which is more shocking: Emma with her hair mussed, face shiny with spit and tongue lolling out, shorts around ankles and breasts swaying, or you with your enormous cock hanging out of your pants, standing at attention between Emma's ass cheeks, twitching softly as it longs for more. The silent moment drags on for ages, and then a hand shoots out and grabs the stewardess by her blouse. It's Emma's.

She pulls the stewardess in close and locks lips with her, her uniformed body now blocking the view of the bathroom from the aisle. The stewardess is so surprised that she doesn't even fight it. You absently note that her name tag reads 'Sherry'. In fact, standing right next to them, you can see that Emma isn't just giving her any light smooch. Emma is using her tongue to search Sherry's mouth, and her eyes subtly change from angry to amorous. Maybe it's the overpowering sex smell. Maybe it's Emma's boldness, after all, it's definitely getting you off. Maybe it's something in Emma's spit now that she's spent so long on Slave4U. But a half a minute later, still locking eyes with Emma, Sherry takes two steps back and pulls the curtain closed that separates the aisle from the back of the plane. You barely manage to maneuver out of the bathroom before she returns and almost pounces on Emma. Emma is happy as a kitten and quickly undresses Sherry from the waist up. You're so bewildered that you just sit back and enjoy the show, stroking your dick while Emma does the impossible and gives Sherry's miniskirt-clad ass a hearty smack. You would probably have gotten sued for doing that just a few minutes ago, and yet, there it is.

Enough of watching, you're in the fast lane now. Use it or lose it! Emma and Sherry's makeout session is spilling out of the bathroom and into the plane's rear room, and you're not just going to hold your dick while it's happening. Emma shimmies all the way out of her booty shorts and tosses them away with a flick of her ankle, leaving her indecently, beautifully, rebelliously nude. You fish your phone out of her pocket and snap a pic. She sees what you're up to and whispers to Sherry, before leaning back against the bathroom door and cocking her hips out. Sherry kneels down in front of her and starts to lick her pussy while Emma giggles and smiles for you. She seems so innocent even though she's just seduced a flight attendant and gotten completely naked on an airplane, which is probably a few different federal crimes. You get another great picture of her throwing up the middle finger and sticking her tongue out while holding Sherry's head down against her slit, which will make a great wallpaper. It'll probably turn up as evidence in a courtroom in a few months, but you don't even care. You're having the time of your life with your manic pixie dream slut.

You put your phone back in your pocket and hurry over to Emma. You start to kiss her as she strokes your cock, Sherry still tonguing her cunt with gusto. Emma moves Sherry's head aside with her spare hand, and you can feel a tongue on your cock as you start to position yourself to fuck your girlfriend. You lift Emma's leg up above your shoulder and smoothly thrust up inside of her, Sherry lubing you up the whole length. It doesn't take long before you gush inside of her, feeling your semen dribble out of her hole and onto Sherry's waiting tongue. This is impossible, you think. I don't care, you think a split second later. You pull out of Emma delicately and Sherry pulls double duty cleaning your cock and sucking cum out of your slut's snatch. You chuckle as you remember the only words Sherry spoke to you when you first arrived: "Welcome aboard, sir, if there's anything you need, I'll be glad to assist."

You and Emma are both panting and out of breath. Sherry unlocks the flight fridge and fetches you both a pair of miniature bottles of rum, which you accept graciously. You all start to come down from your intense sexual high and realize you need to clean up fast. Sherry gets her blouse back on and fixes her hair in the mirror, while Emma rolls her tank top back on and dons her booty shorts once more. You zip up, and you and Emma both give Sherry a deep tongue-kiss before stalking off back to your seats. You're still shaking with disbelief by the time you hit the tarmac in California. You reason that it must have been the gust of concentrated sex smell from the bathroom, combined with Emma's aphrodisiac-laced kiss and the sheer adrenaline rush that kicked Sherry's sex drive into high gear. It could've been a complete freak accident of brain chemistry, all you know is that you had sex with your girlfriend and got a stewardess to help you out and there's no police waiting for you in customs.
