Extreme Heat: Iron Man 3 smut

I don't usually do this, but I saw IM3 last night...and...well...it gave me a few ideas. Probably just a one-shot, enjoy.

Soon after dealing with the “Mandarin” once and for all, at Tony Stark's new house...

Bathrobe-clad Pepper walked into Stark's workshop, where he was scribbling formulas on a sheet of paper in the temporary absence of his holographic computer setup.

“Tony...I know you're working on the cure but-”

“What is it, Pepper? I'm trying to make sure I don't lose you, but I can't finish this formula if you distract me.”

“I know, it's just that I think Extremis changed me more than we thought...I'm really embarassed...”

“Embarassed, Miss Pots? How very unlike you.”

“Shut up.”

“No, really. I kind of like that side of you. When was the last time you showed it? High School?”

Pepper grabbed Stark's underarm and lifted him off the ground with her genetically enhanced strength. “Tony, this is a SERIOUS problem.”

“Jeez Pepper, no need to be hot headed.” Pepper glared at him. “Ok ok, show me what's wrong now.”

Pepper put Stark back on the ground roughly, then pulled her bathrobe apart. A huge dick now sat nestled between her slim and toned legs. Tony's eyes widened a bit, but he recovered quickly.

“Huh...so that's what Killian meant by perfect. Different strokes, and all that.”

“Tony-”

“Does it work?”

“W-what do you mean?”

“C'mon, give it a little fappy fappy. I'm kind of curious about this now.”

Pepper blushed furiously, but silently acquiesced. She awkwardly stroked her soft cock, having never done it from this perspective before. It immediately began filling with blood, and her veins flashed red with the signature Extremis energy as Pepper's arousal caused her to let out a breathy moan involuntarily. Her cock got bigger and bigger, finally reaching full erection even beyond that of hung porn stars.

“Ohhhh, Tony...is this how it feels for you?”

“No, I usually don't masturbate. That's what I have you for, right?” Tony smirked.

Pepper knew Stark was teasing her, but she played along and let herself get a little angry. She felt Extremis powering her body up, and she felt her cock grow slightly. In addition...she felt something else. Something was gathering inside her, and it wanted out. She stroked faster and more roughly, then with both hands. She needed the release, whatever it was. Her whole body was heating up, and it wasn't just Extremis.

“Tony...I...”

“Point it over there, I like being dry.”

Pepper turned slightly towards one of Tony's Ferraris on the other side of the workshop. Suddenly, her brain sparked and she moaned.

“AHHHHMMMMMFF&#8
