She looks flustered

You see Lily sitting upright, legs pressed firmly together. Finally she turns to face you, and you can see she's biting her bottom lip. Her cheeks are red, and her chest is rising and falling rapidly with heavy breaths. You worry she's holding in something difficult, some anger or condemnation.

Then you see the look in her eyes, and her appearance transforms as you see her in a whole new light. Her gaze is wide-eyed and intense, but not hostile. She's not red with anger, she's flush with arousal. Her legs are clenched because she's rubbing her thighs together to stimulate herself. Your fiancee is all hot and bothered, and you think you know why.

"Lily, did you get wet thinking about me fucking the flight attendant?" you ask, your trepidation melting into excitement.

Lily releases her bottom lip from between her teeth as she wiggles in her seat, then gives you a silent nod. You can't help but grin with almost childish glee. Your fiancee is a sex-fiend, and you love her for it, now more than ever.

"Did you do it?" she asks breathlessly, her voice barely audible. Now it's your turn to nod.

"In the bathroom, fast and hard," you reply.

It occurs to you that as amazing as your sex life with Lily is, "fast and hard" could never really describe it. And the thought of finally getting to experience that floods you with a fresh wave of euphoria.

"Fuck, that's hot," Lily exhales, looking up at you, eyes wide.

"I wish you could have seen it," you say, putting your arm around her shoulders. She melts against you, resting her head on your chest.

"Me too," she whispers back, placing her hand on your crotch.

Normally that would have had you hard in seconds, but you're way too sexually exhausted to grow aroused right now. Instead, you settle for letting your arm slip down Lily's back, rubbing it all the way down until you find her ass. You rub and squeeze it, causing Lily to squirm against you and make a happy sound.

"Do you want to get off?" you whisper.

Lily hesitates, then nods her head. She reaches out with one hand between her legs, but you grab her by the wrist. She looks up at you questioningly.

"You can cum, but only if you're thinking about me and the stewardess," you instruct. "Understand?"

Lily gives the tiniest of nods, and you release her wrist. Her hand flies to her crotch, and she slips it beneath her leggings. She wastes no time, rubbing her pussy quickly and with more and more **** by the second. You can see her eyes are closed, no doubt visualizing what you commanded her to, and you hear quiet moans as she bites her lip to try and contain the noises.

It takes scarcely a minute for her to reach climax, worked up as she is, and she gasps out your name as her body convulses against yours. Then she goes limp, head falling to your lap, hand still buried between her legs. You do her the favor of extricating it, noting how her fingers glisten with wetness. You dry them off with a napkin, then look down.

Lily hasn't moved an inch, and from the slow rise and fall of her chest you surmise that she's succumbed to post-sex exhaustion. You smile and pull the blanket tightly over you both, and settle into your chair to enjoy the rest of the flight in your fiancee's company.
