The bumpy ride can’t be comfortable for Loki, and the rough landing must be worse. He doesn’t complain though, he’s too busy strutting over to the bar to crack open a seltzer water. Tony collapses on the sofa with a stretch and yawn, grinning at her with almost as much pride as Loki himself.

“See, Pep? Totally harmless.”

That sends Loki into another fit of giggles, which turn into groans as the convulsions rock his stomach. She hasn’t seen him so energized in all the time they’ve been together. It’s wonderful to see. Grin threatening to split his face, he leans complacently on the bar and takes dainty sips of his bubbly drink and preens like a peacock at Tony’s drunkenly mumbled compliments.

Left to their own devices both of her boys could very well pass out from forgetting to eat, or drink, or sleep. It warms her to see them so well fed and happy. She steps away to clean off her makeup and slip into a cozy nightgown.

When she returns Tony is snoring on the couch while Loki leans on the bar and finishes kicking off his pants. Bare of all but his tunic and socks he’s as lanky and elegant as ever, rubbing absently at his stomach with an easy smile.

“I think I’m ready for bed.” she says.

“Hmmm, bed.” he agrees. Shuffling closer, she can’t help her eyes falling to the heavy sway of his cock under the long tail of his shirt. It’s been a long day, and her eyelids feel heavy, but it’s always a treat to have Loki to herself. His skillset is very satisfying to monopolize.

After a moment of consideration she slips under his arm and walks with him to the bedroom, fingers playing at the silky linen of his tunic. Flicky lazily in the direction of the couch, Loki plops Tony on the far end of the California king and settles himself in the middle. Normally she would fight him for the position, but she supposes he has earned it.

Laying on her side, she snuggles under his elbow and grazes her nails over the bare skin of his legs and over the slight bump of his stomach. With a deep groan his eyes flutter shut and his cock twitches, just an indistinct bulge under the fabric but growing fast.

“You seem pleased.” she says evenly, catching his slitted eyes in a molten stare as she slips under his shirt to touch skin to skin. He hums, almost a catlike purr.

“I’m not accustomed to eating so much anymore.”

The skin of his stomach heats under her touch and he starts rocking his hips unconsciously, breathing steadily heavier at the tease of his shirt on his cockhead. Warmth pools between her own legs at the sight of him relaxing and silently opening himself up to her attentions. His blooming trust always leaves her wanting more once they’ve come, wanting to see how capable he is of being nice and good when the circumstances suit him.

“Anymore?”

Loki’s lip twitch down, just a flicker before it’s hidden. “As a boy I couldn’t get enough. But in the void…”

Not wanting to lose the moment she palms his length and distracts him with slow, sensual touches and raise up on her elbow to align their lips.

“I’d like to see you eat more.” she dares to say, pecking at the corner of his mouth, his cheek, and back to his lips for something deep and hungry. “I worry about you.”

“I forgot how good it feels. To go past full, I mean.” Loki rumbles when they part, his breath rich with all the flavors he’s tasted tonight. He must like the belly rubs, because once both her hands are busy he does it to himself, eagerly shoving his tunic higher and spreading his fingers around the little mound under his belly button. It’s an impressive trophy, his normally trim waist puffed out and swollen with his success.

He’s becoming more and more excited, pulse hammering in his neck as she jerks him faster and faster. Hands wandering up and down his body, Loki stops to pinch at his nipples just as she moves to cup and fondle his balls and he moans, quiet but unrestrained. He’s normally reserved in bed, like he’s been trained over years and years to keep absolutely silent. The lapse of his control makes heat spike in her groin and she throws her leg over his, straddling him and rubbing under her body sings from the delicious friction.

Making up her mind about how she wants the evening to go, she slides the rest of the way between his legs and sucks languid kisses in the crease of his hip. Without a hint of hesitation he spreads for her, bare and begging silently with helpless thrusts into empty air.

“Hmm, you’re so sexy with your little bump.” she sighs, giving in to his desperation and sucking his head into her mouth. Gasping, he hands fly to cup the back of her head, to hold her hair out of her face in that gentlemanly way that Tony’s always too far-gone to imitate. Really, she thinks the world would be shocked by how considerate Loki is. WIth her at least, she can’t know how he is with others, but with her he is nothing short of genteel.

“I-It’s not so small is it?” he says in an unconvincing light tone. Is he self conscious about the size? With a strong suction she takes him deep and pulls off, following her lips with rapid strokes of her hands.

“We can make it bigger.” she says, too light headed to question the strange turn this encounter has taken. Loki lurches in her hand, arching in a fevered thrust that sends precome dripping onto his chest, only to be smeared and spread over his bulging belly in a filthy display.

“Oh, you like that idea? Do you want to get bigger? Want to get all round and sexy for me?” she asks. The words catch up to her after she says them, and in the haze of giving head and the intoxicating tingles coursing through her slick lips all she feels is hot. She likes the idea of Loki being healthy, of his sharp collar bones and protruding hips softening with soft mounds of fat. He would be so much more pleasant to cuddle too, which would surely get Tony on board with it.

Loki comes apart while she contemplates, cheeks flushed and hands dug into the sheets to steady himself against the urge to thrust deeper. She hums, her free hand wandering up to cup and caress his bulge, and that’s all he can take. He comes, his hands tugging at her in warning but she stays where she is. He’s done so good today, he deserves a reward, and sucking him all the way through his orgasm seems a fair trade.

She gags at the taste, and Loki lets out a high noise like a bird, the sudden tightness sending him even higher into ecstasy. It seems to last a long time, his body twitching and eyes wide and unfocused at the overwhelming rush. She pets him through it, all the way up to the dip of his pecs and back down to his swollen belly, slowly and sweetly coaxing him through wave after wave. Sadly she needs air to live, so she eventually has to slip away and cough through the uncomfortable mouthful.

“By the stars.” Loki pants, covering his face with his arms and bucking mindlessly into the circle of her hand, drawing out the final descending aftershocks. Once she can finally breathe normally she wipes her mouth on his shirt and smiles.

“That looked like a good one.”

“Verily.” Loki groans. That indolent smile makes a comeback, stretching across his face like it’s unfamiliar land and it’s not sure where the boundaries are. She’s certainly never seen him smile so much in one evening before.

Straddling his leg, she drags a hand down her own stomach and rubs indulgently at her clit while her lips spread and slide over lean muscle. With sex drunk eyes Loki observes, the heat of his gaze driving her higher rather quickly.

“Do you want a hand?” he asks, although she can tell by his sleepy expression that he’s drifting off.

“Well I already have this very comfortable leg.” she says, although it comes out closer to a pitchy sigh. It really would be a better ride if Loki gained a little weight, just a little bit more of a cushion for her to plow into...yes, that would be just perfect. She pictures him, plumped up and happy like he is now, bent over the dresser so she can see his newly rounded ass wiggle when Tony fucks him.

Lazily, Loki sits up and drapes his arms over her shoulders, holding her close and hunching to lick and suck at her nipples and the nape of her neck. Long, sensual pulls with just the right amount of teeth to send hot sparks through her core. Her breath sticks in her throat at the rush of pleasure and Loki smirks, always a good sign in the bedroom.

“I believe we can make it more comfortable.” he says, barely more than a gravelly whisper as he slips his right hand between them and a little egg vibrator materializes in his hand.

‘Oh fuck, yes.” Pepper smiles, throwing her head back and angling her hips up to give him room. “You have the best ideas.”

“I have very inspiring muses.”

Loki drives the slim silicone between then and after he turns it on Pepper’s grasp of the situation turns into more of a blurry rush. Unlike Loki she is not at all quiet or polite. She rides his leg until he’s half asleep under her, just gazing at the rhythmic bounce of her breasts and holding the vibrator still for her to rut against. The final orgasm seems to roll over and over, the pleasure shooting up her chest and around her neck and buzzing, deep and delicious through her tired muscles.

“Mmmmm, thank you.” she sighs, satiated and exhausted. Loki chuckles, turning off the vibrator and guiding her to lay between him and Tony. The sheets smell musky, rich with the scent of her men and a faint sex stink that she’s learned to like well enough. She presses up to Tony’s back and hugs him from behind, curling close to the wall of his strong body and melting when Loki presses up behind her, locking her between them in a safe little valley. Her favorite place to be.

She wants to kiss Loki goodnight but that would require rolling over, and that’s just too much effort. Instead she satisfies the urge with a firm peck between Tony’s shoulder blades that bring up into a drowsy half-sleep.

“Wassit?” he mumbles, flopping on his back and blinking blearily. His nose wrinkles, and then his lips turn in a playful glare. “Awww, did you guys do it without me again?”

Loki’s rumbling snickers join her softer giggles and Tony throws his pillow at them. Chuckles become deep bellowing laughs.

“Dammit, you could at least let me watch. Or hell, record it. Jarvis, did we get a recording of that?”

“I expressly forbidden to record intimate moments without unanimous consent, sir.” Jarvis says without an ounce of apology.

“Oh come on.” Tony grumbles, rolling back onto his side with a huff. His head hangs uncomfortably with his pillow and without so much as a word Loki kicks it off the backside of the bed.

“I hate you all.” Tony says, throwing off the covers and stomping around to find his pillow in the dark.

“You’ll just have to stay awake next time.” she teases, tossing the covers over her and Loki and settling into a growing sleepiness.

“Next time?” Tony says, pausing in his search. “Why do you need to specify a next time? Next time for what?”

Loki smiles in Pepper’s neck, and she wordlessly agrees to keep this a surprise.

“Goodnight, Mr. Stark.” she intones, and ignores any further questions.
