This very very late, but this is part of the Darcy Smut challenge.
Darcy stood in front of the microwave in the lounge area of the tower, watching as the timer clicked down. She had put a couple of S'mores in there, having a huge chocolate craving that she couldn't for the life of her get enough of. "Oh thank god." She flung open the small door and grabbed the first S'more. Biting down into it, chewing quickly to eat the whole thing. "Dang it." She groaned as she finished it, the marshmallow wasn't cooked enough and the chocolate wasn't melted enough. She was not satisfied.
She glared down that the plate that had the remaining s'more like it was all its' fault. "Damn you to hell." She growled.
"Well I don't know what I did this time." Johnny stated as he walked into the room. "But I'm sorry."
"Not you." Darcy stated as her glare remained on the S'more. "It's not doing it right."
"Doing what right?" He asked standing next to her.
"The S'more, it isn't doing its job."
"Being the perfect S'more." She wined. "All I want is the fantastic campfire S'more without the whole campfire."
"Well maybe I can help with that Lewis." He picked up the Marshmallow and set his finger on the chocolate, flames burst out of his hands and instantly the chocolate melted and the marshmallow cooked. He put the S'more together and handed it her. "Here you go." He smirked as he watched her picked up the messy treat and take a big bite out of it. She let out a moan and licked her lips. "Is the perfect S'more now?"
She licked the runny chocolate off her hand. "It's so perfect, I may be in love with you."
"For my S'more roasting skills?" He laughed as she finished eating the treat.
She chewed the rest and swallowed it. "Well you're hot to." She shrugged, "So I guess you got two things going for you." She sighed and looked down at her plate. "To bad we don't have anymore, I would kill for another one."
Johnny frowned, looking around. "We don't have anymore?"
Darcy shook her head. "Nope."
He sighed. "Damn and now I wanted one." He smirked. "Guess I'm going to sample yours'."
She arched an eyebrow. "I just ate mine Storm."
He smirked and cupped her cheek. "I can still taste it." He whispered as he kissed her, wrapping his other arm around her waist. She moaned into him as she wrapped her arms around his neck, pulling him closer as she opened her mouth.
He could taste the S'mores, the marshmallow and chocolate still on her lips and his tongue brushed against her lips. He pulled her close as he pushed them against the counters. His hand on her waist crept up underneath her shirt.
"Seriously you two?" Tony groaned from the doorway. "There are others who eat in here."
Darcy and Johnny pulled away from each other to glare at Tony. "We were busy here." Darcy growled.
"Yea, I was just wondering when this honeymoon phase was going to end because I can't deal with this and save the world." Tony stated with annoyance as he walked to the coffee maker.
"Until we screwed in every room of the tower." Darcy joked.
Tony rolled his eyes. "Been there, done that."
"If you don't mind." Johnny stated. "We're leaving to go to the grocery store."
"What do you need? We have everything here?" Tony looked around confused.
"We're out of chocolate and marshmallows." Darcy smirked and Johnny's hand on her waist squeezed a little.
"God, just go. Go on and have your kinky sex elsewhere." Tony left the room in a huff without his coffee.
"I wonder if we can get away with having sex in his lab?" Johnny asked.
Darcy smirked and looked up at him. "S'mores first. We're not finished yet." She pulled him down for another kiss.
