Smatters glides lazily up and down the central aisle, his shadow casting itself across the beige carpeting and creme walls. Ms. Carte and the twin Spancers are in the cockpit, piloting. This leaves just you, Whitney, and Mom to while away the 15 hour trip together.
Of course, there isn't an in-flight movie.
What the flight does have is ample space and nicely adjustable seats.
You lie atop your mother, the seatback reclined to its limit. You fuck her as deeply as your cock can reach, the tip of it kissing her womb. You bask in the soft give of her flesh underneath you and the hot, inviting folds of her most intimate place. You squeeze her breasts, each one warm and weighty in your violating hands. You entwine your legs with hers, angling yourself so that you can force your throbbing dick to its root inside her.
Your jackhammer thrusts transform your hips into a blur of motion. Mom's head lolls to one side as she cums wetly around you, doped on incestuous pleasure. You can feel her shuddering from the inside-out.
When she speaks, her voice has the quality of someone talking through the whirring of electric fan blades. "Al-aa-baaa-ssterrr," she groans. "Yoo-oou're beee-ing t-tooo rouuuugh--"
She says this -- but even as she does, she runs her fingers through your hair and draws your face closer to her neck. Her cream pools on the faux-leather seat underneath you.
It is true you're being rough, though. You want to be rough. You want to make sure she remembers the shape of your dick and the hot, filling sensation of your seed pouring into her. No matter what happens next, she won't forget that. You won't let her.
Behind you, Whitney watches the spectacle. Her spats are bunched around her ankles and her legs are spread wide as she masturbates openly. She uses one hand to molest her own cunt and the other to tweak her nipples, first one and then the other. She chews on her lip and her face contorts in orgasm as she drinks in the lewd show.
"I'm cumming," you tell her. You don't break pace.
She grunts and groans unintelligibly, twists and turns her face from side to side. She tries once more to speak, but the exertion of getting fucked so hard robs her of breath. She begins to pant like a bitch in heat as your orgasm mounts and you prepare to let go.
You make a guttural noise and blow your cum inside. She reaches down to grab your ass, as if trying to force your spurting cock even further inside her. Her belly, arms, and neck muscles go taut, straining, as you mark her with your semen.
As always, very few sensations can compare to relieving your aching lust inside your own mother.
When you finish emptying yourself, you dismount. Dazed, you stumble back and fall into the seat beside Whitney, who's still busy masturbating.
Whitney sees her opening. She stands, kicking off her spats. She falls to her knees in front of Mom and pushes Mom's quivering knees apart. When she catches sight of the mingled fluids spilling from Mom's cunt, she licks her lips and coos in delight.
"Stop--" Mom says breathily. She runs a hand through her sweat-slicked hair, trying to muster energy. "Wait... if you do that so soon... I'll go craz-- unnnffff--" Whitney cuts Mom's protest off by latching her lips around her pussy. Mom writhes, lifting her butt from the seat and arching her back to offer herself up to Whitney's suckling mouth and tongue.
You slump in your chair and enjoy the sapphic obscenity.
