The door to the bedroom slammed open as Tony was kissing you passionately. The whole ride back home was pure hell for him who couldn't wait to feel you and make sure you forget all about Steve and the others. You seemed to be too drunk to protest and your love for Tony got the worst of you. The whole day didn't go fair, but you didn't manage to protest.

"Fucking provocative dress." He mumbled, taking it off of your body. "Dressed up all pretty for them, didn't you?" He growled, placing kisses over your cleavage, making sure to leave marks. He loved creating them, knowing he was the only one to do so. "Just for you, Tony." You moaned out loudly, as his fingers rubbed over your panties. He placed you in the middle of the bed, towering above you. His hand reached behind you and unclasped the black lace bra you were wearing. He quickly drew all his attention towards your breasts, licking and biting your nipples. You were a moaning mess when he suddenly stopped. You looked down, confused, only to be met with his brown eyes. He seemed to be thinking of something before a smirk appeared on his face. "Ride me." He said and your lips parted when you remembered the deal. Your expression quickly changed, desire flashing in your eyes. Tony sat, leaning against the headboard of the bed. In a flash, you were straddling him, kissing his jawline and the spot under his ear which drove him wild. A silent moan left his lips, which got you even more wet than you already were. You loved all of the sounds he made, even if he wouldn't let you hear him often. Probably he didn't find it manly. His hands were now squeezing your ass, enjoying the fact you wore a thong, one he bought you.

You took off his shirt and threw it to the side. You were about to unbuckle his pants, when he pulled you into another kiss, biting your lower lip. You moaned into the kiss and felt his bulge under yourself. His one hand reached into your panties and started to rub your clit. "I want you, daddy." You moaned seductivly grinding against his hand. "Mhh." He hummed, satisfied with the name. "Go ahead, then, sweetheart."

He placed his hand on the sides of the headboard, letting you do everything. You took his errection out and fisted him a few times, all while looking into his eyes. The feeling of your small hand around his cock got him excited, as he started to become inpatient. His jaw clenched and you knew you should do something by know. Still, you enjoyed teasing him. He was about to snap, when he suddenly saw you pushing your underwear to the side and sitting down on him. He sank right im and you took a deep breath feeling the stretch. "Tony..." You whined. "You'll take it, I know you can." He said his hand coming up to your cheek, caressing it softly. "My good girl." He mumbled out kissing your neck. That was when you gained confidence and started to ride him slowly at first. You picked up your path and were now moving faster on top of him. Tony's head was thrown back in pleasure. He couldn't get enough of you. His strong hands landed on your hips, guiding you gently. You had to place your hands on his chest for support. His tongue came out to wet his lips at the sight.

The light of his arc reactor illuminated on your face and he saw sweat forming on your forehead. Your eyes were shut in pleasure, lips swollen from all the kisses. Your breasts jumped with every move, covered in hickeys. He left one on your neck. Shape of an heart. "I'm close, Tony, please." You moaned out. "Please what." He demanded. "Fuck me!" You whined out looking at him with innocent eyes. He smirked before pulling out of you. "All fours." He said patting your upper thigh. You didn't waste time and got on your hands and knees, pushing your ass up. A harsh slap could be heard and Tony hummed out, satisfied as he saw his handprint on the cheek. You were about to beg for him to do something when he thrusted into you aggressively, pushing your head into the pillow. He fucked into you fast and hard, just how you liked it. Your moans were muffled as you couldn't keep your orgasm any longer. Tony noticed it too, feeling your walls squeezing him impossibly tight. "Cum." He said, and you did, cumming over his length as you squeezed the sheets in your hands. You felt him fill you up as well. As he pulled out you whined, feeling the emptyness. "You did so good, baby." He praised and turned you around, kissing you lustfully, before disappearing into the bathroom and coming back with a wet cloth to clean you up.

Later that night, your head was layed on Tony's chest as you slept peacefully. He was awake for the past few hours. Watching you sleep. You looked angelic to his eyes. Your perfect body wrapped in a thin sheet and letting out small snores every now and then. He on the other hand, had massive troubles sleeping, to the point where it was dangerous for his health. He had dark circles under his eyes, which looked red due to the dryness. A sigh left his mouth as he got up from the bed, carefully placing a pillow under your head, to not wake you up.

Time didn't seem to pass. Tony had been in the lab for half an hour by now and continued staring at his watch. His eyes followed the tracker, that seemed to move in slow motion. He was deep in thought, which resulted in not hearing the door open. You stood there watching him with a frown on your face. You were wearing Tony's shirt, nothing underneath, so you started shivering.

"Tony?" Your small voice could be heard through the room. He flinched at the sound and quickly turned to look at you, which seemed to be too much. He felt dizzy and saw some black dots appearing in front of his eyesight. He blinked a few times, expecting it to pass, which it did not. He stumbled backwards gripping his desk to keep up. You quickly came to his side supporting his weight. "Is everything okay? Why are you not in bed? What happened?" You asked, looking panicked. His eyes closed again, in an attempt to come to his senses. Even your voice seemed distance to his ears. When he opened his eyes he saw a glass of water you held to him. He quickly grabbed it, downing it in two sips. Fortunately, it helped and he now saw your worried face. You called his name again, which got his attention this time. "Yes?" He replied, raspy voice. "A-Are you okay?" You asked, confused about his calmness. "Absolutely." Your lips parted and you went to protest. "You can go back to sleep Y/N." He said, looking straight into your eyes. "I can- what? Are you out of your mind? You almost passed out!" You said raising your voice. You couldn't help it. He wasn't taking this seriously. His eyes met yours again and you zoned out. They seemed tired and restless, making shivers run down your spine. He breathed out sitting down on his chair. You bit on your lip, nervously, thinking of what to do. Your thoughts were interrupted when he suddenly called your name. You looked at him expecting a reply.

"You should move in. Live here."

What? "What?" You asked, thinking you heard him wrong. "Live with me." He said, again, expression stone cold. "I-" You started, but stopped, meeting his gaze.

"Come on, let's get you to sleep." You spoke softly, this time, helping him get up. He was about to say something. Protest. Say no. But he stayed quiet. You fascinated him, again. There was something about you that got him into this relationship. Before you he wouldn't even bother to think of having a girlfriend, but with you he felt different. You made him feel something, he thought he wouldn't feel again.

You cared about him.

That's how he found himself, laying in bed, head placed on your stomach. It was an unusual situation of physical touch you two didn't share often. Your manicured nails glid through his hair, caressing his scalp. It was around an hour later, when, finally, you heard his breathing slow and calm. You peeked your head forward, only to see his eyes closed, features looking, well... peaceful. It was a mood you seldom saw him in. A small smile crept up your face and layed back down, calmer than before. With a satisfied look on your face, you fell asleep as well.
