Okay so loads of you have been asking for dominant Jace with Clary and the only way I could really think to do it without their feelings getting in the way (I know I know it's fictional) was if they weren't together, so this is set when Clary first arrived at the institute and Jace does not feel romantically for her whatsoever, he just thinks she's hot XD

All characters belong to Cassandra Clare!

Clary pushed the door to the room open. She had never been in this room before, she had only ever seen Jace enter it once or twice. Before she entered she didn't really think there would be anything significant about it, she thought it would just be any other room which she would look around briefly and then leave, she was just trying to learn her way around the building. What she wasn't expecting was to see Jace standing in the middle of the room… in a leotard. He was standing with his arms held aloft half way through a plie which Clary could only identify thanks to her ballet lessons as a young girl.

"Jace?" She spluttered.

The golden haired head shot up and his eyes met Clary's, filled with rage. He straightened up, his muscles clenching which would have been comical thanks to the skin of the leotard, the pink leotard clinging at his body but he looked so filled with rage that Clary considered running from the room. As she turned to the door though, he grabbed her in his steel iron grip, pulling her towards him.

"What the fuck are you doing in here, Fray?" He spat.

Clary's lips parted, she opened and closed her mouth constantly like a goldfish. She tried to struggle against his hold but it was no use, he wasn't only a strong boy, he was a strong shadowhunter, even if she punched him with all the force she could muster it probably wouldn't hurt him. "I… I was just exploring and I-"

Jace relaxed his hold on her slightly but he didn't release her. He clenched his jaw, staring her down.

"Didn't I tell you to stay in your room anyway?" He said, his words laced with venomous anger.

Clary's wide innocent eyes made him feel sick, her little girl act was starting to get tiring. "Isabelle came in and asked why I was sitting staring at the wall, I said you told me to and… and she said not to listen."

Jace yanked her arm, hard. "Well you listen to me, not Isabelle, not even Alec and Hodge, me! Do you understand? I bought you here, you're my guest."

"You're not treating me very well for a guest." Clary retorted angrily, though she instantly regretted it when he flared up with even more rage.

"Fine. You want me to treat you like a guest? I'll treat you like a guest."

Still holding her, he used his free hand to slam the door shut and lock it, and then he pulled Clary to the centre of the room.

"Strip." He barked.

Clary hesitated, her hands hovering uncertainly at the edge of her borrowed top from Isabelle. Irritably, Jace rolled his eyes and ripped the shirt off of her, dropping it to the floor. She wasn't wearing a bra, and gasped loudly when Jace reached for her boobs and squeezed each nipplee hard.

"Ow!" She hissed, "Jace, what are you-"

"Shut your mouth, Fray." He sneered, hands going to the poppers of his leotard. Seriously, it has poppers!? Clary thought to herself, Is he a baby now?!

His giant dick freed itself from the leotard, but he kept it on the rest of his body.

Clary let out a shaky breath, she had been thinking of seeing his cock for days but didn't think it would be like this, she thought it would be romantic and that he would tell her loved her, she had imagined his gentle hands holding her carefully like a delicate doll… but then she did love him, he didn't really love her, did he? She probably didn't even love him but she definitely thought having sex with him would be a lot nicer.

"It's not going to suck itself." Jace snapped, shoving Clary's shoulder down so hard that instead of landing on her knees she just fell in a heap on the ground.

She knew there would be a bruise there later as the floor was stone, but didn't bother complaining, clearly he didn't care. She got to her knees and stared at his member uncertainly, she had never seen a dick before.

"I don't know how…" She started, but she was interrupted by his cock entering her mouth uninvited. She would have gasped but her mouth was so full of dick she couldn't make a sound, it was rubbing against the back of her throat. He had his hand in her hair and was yanking her head backwards and forwards, seemingly forgetting her head was attached to her neck, it was straining so much it hurt. This went on for a while, Jace made low, growling noises which she found so sexy and masculine, despite him being in a leotard he was still so hot.

He pulled out of her and told her to close her eyes. When she didn't, he just shrugged and started rubbing his cock with his hand, and then he squirted cum right onto her face.

"Shit!" She cried out when a drop landed in her eye.

"Well I told you to shut your eyes and you didn't listen to me,it's your fault for being a stupid bitch."

"Excuse me?!" Clary spluttered.

"Shut up Fray." He rolled his eyes and then, still with his hand tangled into her hair he pulled her to her feet and started marching her to the table in the corner while she was still blinking cum out of her eye.

She barely registered what was about to happen when he had her bent over the table, he pulled her trousers and knickers down and he was pounding into her so hard that she screamed and her body writhed in pain, though she couldn't move under the weight of his hold of course. The realisation hit her then, this was how she was losing her virginity.

"Jace, I really don't care if you do ballet you didn't have to fuck me- ah!"

She started moaning against her own will then, she didn't want to be enjoying it… though if she wasn't it would have been torture so it was slightly good. He came again, only this time inside of her.

"Are you wearing a condom?" she gasped, turning her head to look back at him.

He rolled his eyes, "We'll get Magnus Bane to fix you up a fetus deletus potion."

He pulled out of her and then started slapping her butt, leaving scorching red hand marks against her pale cheeks.

"You're not going to tell anyone about this, are you?" He grunted, pausing in his spanking.

"No." Clary squeaked, letting out a mewl of pain as he connected his hand to her ass again.

"And you're going to listen to everything I say and never disobey me?"

"No!"

Spank, spank, spank.

"Are you going to be my little bitch mundane?"

"I'm not a mundane-" Spank, "Yes! Yes."

"Yes what?" He growled, spanking again.

"Yes I'll be your little bitch mundane." Tears pricked the corners of her eyes and she waited for him to slap her again, but he just closed the poppers of his leotard and walked back to his balance beam.

"Go to your room and finger yourself, don't stop even if somebody enters the room." He said tiredly.

"Yes. Okay," She gasped, and then pulling her jeans back up she fled from the room.

Also idk why I added Jace in a leotard, the idea just came to me and I found it funny haha XD Yeah this is more of a comedy lemon I think… hope that's okay with you guys!
