Author's Notes: This could be 616 comics continuity but I was imagining MCU because Cobie Smulders is so hot. Tony and her finding a quiet room at the back of the licarrier during Avengers Assemble.

Maria Hill couldn't believe the position she'd found herself in. She was stripped to her underwear, and her wrists and ankles were tied to the bedposts, spreading her body for all to see. Tony Stark stood, taking a sip of the drink in his hand as he looked her up and down. Maria was always so detached and professional. How had he broken down her defences so easily and got her to agree for this. She tensed up as he reached out to trail his finger slowly down her smooth, flat stomach. The ice cubes in his glass clinked as he took another sip.

"Relax Hill, it's just a little bit of fun. You know you want this." He murmured in his usual sarcastic tone, teasing her.

"But I'm still not going to make this easy for you." She shot back with a grin on her face.

He placed the glass on the bedside table and moved up closer to her. He ran his finger over her lips, tracing their outline before dipping it into her mouth. She sucked on it, flicking her tongue over the tip of his finger. He moaned, leaning in closer.

"Fuck Maria, you're so hot. I can't wait to see how you look when you come undone." He whispered in her ear before moving away to take another sip of his drink.

The coolness of the ice cubes sent shivers down her spine as he trailed them down her chest, circling her nipples before moving down further. He teased her clit with the ice, making her gasp before he finally slipped a finger inside her. She moaned, arching her back as he moved his finger in and out of her slowly, building up a rhythm. He watched her face, loving how he could make her lose control.

She was so wet and ready for him that he couldn't resist any longer. He slipped off his pants and climbed onto the bed, positioning himself between her legs. He teased her entrance with his cock, making her squirm before finally pushing inside her. She gasped as he filled her up, moving slowly at first before picking up the pace.

"Fuck Tony, harder!" She moaned, urging him on.

He grinned, obliging her request as he slammed into her over and over again. Her legs tried to kick in pleasure but the ropes around her ankles kept them forcefully in place. He could feel her walls tightening around him as she got closer and closer to the edge. He reached down to rub her clit, sending her over the edge.

She screamed as she came, her orgasm rippling through her body. He groaned, following her over the edge as he came inside her. They lay there, panting and sweaty as they caught their breath.

"Fuck Stark, that was amazing." She murmured, her neck arching up so he could kiss her.

He grinned, kissing her oblingingly. "I told you it would be."

He untied her wrists and ankles, pulling her into his arms as they lay there in silence. Maria couldn't believe what had just happened. She had never let anyone tie her up before, but there was something about Tony. And she was glad she did because that was the best sex she had ever had.

"So, do you want to do this again sometime?" He asked, looking at her with a mischievous glint in his eye.

She grinned, kissing him again. "Only if you promise to make it even better than the last time."

He chuckled, pulling her closer. "Don't worry Agent Hill, I always deliver."
