This is very sexual. Clary is 18 and Jace is 29, so if you don't like that...

Disclaimer: I don't own TMI


God, he's so sexy, standing there and writing on the board. The muscles in his arm are flexing so deliciously. I can just imagine other muscles flexing under his black t-shirt. He probably has abs since he looks like he's in such a good shape. Especially his ass. It looks so nice in his black pants.

He turns around, revealing his angelically handsome face. I can almost hear all the female students sighing.

"Who can tell me the answer?" he asks. I turn to look at the complicated math equation on the board. I have no fucking idea what the answer could be.

Since Kaelie seems to be the only one who knows, she gets to answer. She used to be so bad at math, but when Mr. Herondale became our new math teacher, she suddenly got so good. But I think she has the wrong tactic. Sure, she gets some compliments from him how well she did, but that's it.

I on the other hand… I don't actually have any tactic. I just really suck at math and I can't seem to understand no matter how hard I try. So, me sucking at math got me some tutoring with him after school. There's something else I'd like to suck. But I'm afraid that is not a part of our tutoring sessions. Yet.

As Kaelie answers the question, her voice is very sultry and she's trying to push her chest forward. Mr. Herondale remains unaffected. It makes me so happy.

Again, she has the wrong tactic. Like Kaelie, I don't dress too slutty. I always wear sexy clothes to school to impress him, but at least I can say that I'm wearing something. Kaelie's clothes are more like strips of fabric. Today I'm wearing very tight black jeans and a red lacy top that reveals appropriate amount of cleavage. The color of the top matches pretty well with the red of my hair and brings out my green eyes more.

Kaelie has never gotten any reaction out of him no matter how hard she tries. She just doesn't know the right moves. But I do. I always innocently tease him during our tutoring sessions. Like how I always put the tip of my pen into my mouth and suck it slightly. It probably looks so innocent to him. He doesn't realize that I do it on purpose. I always notice how his eyes darken and he gets this heated and nervous look on his face. The nervousness is there, because he isn't supposed to feel like that toward one of his students. Other thing that makes it more difficult is that I'm 18 and he's 29.

Even though he's quite old, he still looks amazing. He has aged so well. It suits him. Okay, he's not that old, but he is almost in his thirties. Somehow the age difference makes it all so much hotter. It also makes me hot to think that he's my teacher. I bet all the female students have some fantasies about him. I don't think anyone of them leaves the class with completely dry panties. I know I don't.

Kaelie answers correctly, earning a compliment from Mr. Herondale. She looks very pleased with herself and I just want to laugh out loud. But I'm so glad she was not smart enough to realize how she could get him to tutor her if she'd be bad at it. Who knows what she'd try if they'd be alone in a same space.

I can't wait for the tutoring after school. I just love teasing him. I think I even got him hard once. He always leaves the classroom with me, since his workday ends there. Once he looked very uncomfortable when I asked if he was gonna come too. He said he was gonna finish some paperwork. If he would've had some actual paperwork to be done, I'm sure he could've done that at home.

There was a really good chance that he could've gotten hard since I did wear a dress that day that revealed a bit more cleavage than usually. I kept 'accidentally' leaning so that it even probably showed a bit of my black lacy bra. I'm still pretty sure he thinks I'm so innocent. With my looks it's possible. I'm very short and I even have some freckles on my face. And I just have this innocent look.

I wish I could do more. I'm feeling so horny today and I just want him. He makes me feel so hot. I want to feel if he has those muscles under his shirt. I want to feel if his golden blond hair feels as soft as it looks. I want to feel how hard I can make him.

I snap out of it as the bell rings. I even out my breathing, seeing as it got a bit heavy while I had my inappropriate thoughts about my teacher.

I pack up my things and walk towards his desk. He's sitting by the desk, going through some papers. He lifts his head and smiles at me. That smile does so many things to my body.

"So, I'll see you at the tutoring," I say, using my innocent voice, 'cause I know it drives him insane. I've noticed how turned on he gets when I act all innocent. I'm very good at reading his reactions. Right now I can see how his golden eyes got a shade darker and how he quickly licked his lips. I just want to jump to the other side of the desk and…

"Yes, I'll see you then. Have a nice day, Clary," he interrupts my thoughts. And I'm glad. I don't know what he would think if I'd suddenly start panting while looking at him.

I give him one last smile and walk out of the classroom.

"Did you see that? The way he complimented me?" I hear Kaelie talking to her friends. I have to bite my lip so hard to keep my laughter inside me. How can she be so stupid?

I can't concentrate on anything for the rest of the day. I just want him so much today. Of course I want him every day, but today the want is just so much stronger. I hope I don't do anything stupid.

Finally the moment comes and I get to see Mr. Herondale again. Or Jace, but I like calling him Mr. Herondale. And I know he does too, maybe even too much. That's why he insists that I call him Jace when we have our tutoring. But I call him Mr. Herondale anyway. Of course I do, it's part of my teasing.

I go inside the classroom and see him writing something down. He has pushed the two desks together so that we can sit across from each other. He always does that, but I think he has started to regret his decision since I can so easily tease him when he can see me all the time.

I walk to sit down across from him and he lifts his head. And there is that damn smile again.

"Did you have a great day?" he asks politely.

"It was okay." You know what would make it great? If you would take me right here, right now on this desk. I wonder what his reaction would be if I'd actually say that. I bet his day would be great too if he'd take me right on this desk.

He starts trying to teach me the equations, trying his best to make me understand. I do almost get it. I think.

He tells me to work on the worksheet he gave me. And now is time for the show to begin. I suck the tip of my pen as I wonder what the answer could be. I lean over slightly, revealing a bit of my cleavage. I let my tongue slip out a little as I keep the tip of the pen in my mouth. I can hear his breathing getting heavier. I lift my head to look at him. He once again has that nervous, yet really turned on look on his face. It makes me so hot.

"Is something wrong, Mr. Herondale?" I ask innocently. I notice him muffling a groan. He clears his throat before answering.

"Why would anything be wrong?" he asks, frowning.

"Your breathing is a little heavy. Are you sure everything is okay?" I ask concerned. Inside I'm grinning mischievously.

"Yes, everything is fine. I just have something in my throat. Anyway, did you finish the work sheet?"

"No, I still don't really get it." It's true, I really don't get it. I don't even want to get it. I just want him!

He leans over to show me how they're solved and I can smell his scent. It's so fresh and manly. I can also smell how his breath smells like mint. He's driving me insane.

"Do you get it now?" he asks as he finishes explaining, looking at me. I'm always so mesmerized by his golden eyes. They always seem to be so much darker shade when he's with me than what they are when he's teaching in class.

"I think so." I really do start to get it. Thankfully there still are things that I don't get, so these tutoring sessions are not over yet.

He then gives me time to try to do the rest of the paper. I do manage to put some answer to every part. I just don't know if they're correct.

Now I 'innocently' keep my finger in my mouth since I'm writing with my pen. I don't know if he's actually so oblivious that he would believe that I'm so innocent.

I can see him slightly squirm in his seat. I'm getting so turned on that it's almost painful. I need a release. Preferably from Jace, but I guess I'll just have to take care of myself alone in my bed tonight.

I can hear his heavier breathing easily in the quiet classroom. We're one of the few people still left at the school. I know that the other few are at the office which is at the other side of the school.

I finish the paper and look up. The look on his face is so hot and predatory that I'm almost taken aback. Fuck, I want him so bad. He snaps out of it and takes the paper I'm trying to hand him.

He goes through it and when he looks up, he's grinning at me.

"Every answer is correct."

"Really?" I ask, excited and he nods. I get up from my chair and so does he. We hug, both of us happy that I finally start to get it.

"I knew you could do it," he says as he hugs me into his strong body. I notice that I can feel something hard poking me. Oh god, I know just what it is. The urge to get my release is so strong that I feel like I can almost explode from the feeling of his hard-on trying to get through his pants.

We're still hugging and it's getting a little awkward. But I don't really care. I push myself more against his hard-on. I can hear his breathing getting heavier and his arms tighten around me.

"Shouldn't we let go already?" he asks, his voice so deliciously hoarse.

"No," I say and push myself more into him. He groans. He gets harder and harder.

"We shouldn't do this."

"No one's gonna have to find out," I answer and slightly grind against him. He lets out a louder groan and presses me tighter against him. I whimper quietly to his ear.

"Fuck. I've wanted you so badly. We should really not do this." His voice is low and so full of pleasure that he's not sounding very convincing when he tries to say that we can't do this.

I lift my head from his shoulder to look at him, still slowly grinding against him. His eyes are hooded and his lips parted. He looks so incredibly sexy right now. I'm so close. I have been so turned on today, so it won't take very long for me to come.

I whimper again at the predatory look in his eyes. He lifts me up and I wrap my legs around him. He pushes me against the nearest wall, pushing more into me. Both of us moan. The friction is so much better this way.

"Tell me we shouldn't do this," he pleads. But I hear the exact opposite.

"No one is ever going to find out and we're both adults. I'm a senior and I graduate in few months anyway. There's no reason why we shouldn't do this, Mr. Herondale." It's so hard for me to talk as all I want to let out are moans and whimpers. Jace lets out a loud groan as I refer him as Mr. Herondale. I think that's all I need to convince him, since he's grabbing my hips more and pushing against me faster and harder now.

I'm so close. I can feel it coming already, and it's going to be so strong. As he keeps bucking his hips more and more, I finally feel the orgasm take over my body. I feel like I can feel it all over my body. It feels like it lasts and lasts, wave after wave. I'm lifting my hips uncontrollably and letting out small whimpers since that is all I can manage. When it finally ends, I open my eyes. Jace is looking at me amazed. He doesn't seem to be able to form any words and is just looking at me as I calm my breathing down.

I can still feel him hard against me, meaning that he didn't cum. He snaps out of it as I grab him through his pants. He groans and I start to feel the heat coming back to me. Only he can have this effect on me. He feels so hard and thick on my hand. I unwrap my legs from around him and he lets me down. I get down on my knees in front of him. I continue stroking him and he lets out those small grunting noises. I look up at him under my eyelashes with an innocent look.

"Do you want me to suck your cock, Mr. Herondale?" He looks like he's ready to explode right now, which he probably is. I know exactly what this is doing to him.

"I can't believe I'm doing this. I want that so fucking bad. You have no idea how many times I've imagined those pretty lips wrapped around my cock." I guess I convinced him pretty well as he can talk like that. It's getting me so hot to think that he has thought about me that way.

I undo his pants and drag them down his legs. His boxers are so tented. It looks so big and I don't know how I'm gonna be able to do this. I waste no time as I drag them down too, revealing his huge cock. I feel so proud as I see how hard I made him. I also feel very turned on at the sight of him. I carefully take it into my hand. It feels so smooth and warm. I can feel Jace's gaze on me. I finally take the head into my mouth, looking up at him. He grunts loudly and brings his left hand to tangle it into my curls.

He pushes me slightly, encouraging me to take more. I take as much as possible, but I can barely take half of it, because it's so thick and long. Jace seems to enjoy it either way, those sexy groans coming out of him. I keep moving my hand on the part that I can't get in and move my lips and tongue. His hand is grabbing my hair tighter, not tight enough to really hurt that much. I don't even care that it does hurt a bit, it just makes me know how much he's enjoying it.

Jace pushes my head more into him and keeps thrusting his hips slightly.

"I'm gonna cum," he warns me. I move faster, looking into his hooded eyes. His breathing is very fast. He's almost fucking my mouth as he's so desperate to cum. Soon he lets out a loud groan and I feel him coming into my mouth. There's so much of it, but I just keep swallowing. I swallow the last bits of his cum and he opens his eyes. He looks down at me as I lick him clean.

I stand up and he puts his pants and boxers back on. And then we're just standing there.

"So, I think this tutoring session is over." I can see how he's desperately trying to be serious, but there's a grin trying to break through. I step closer to him. I'm not done yet.

"Unless, you'd like to continue it in your place. I don't think I'm done quite yet." I lean my face close to his and look deep into his eyes. He raises one eyebrow.

"You're not?" I shake my head. I can see the fight going on inside his head. Then he sighs. "Fine. Let's go." With those words, he takes me to his car and drives off fast, eager for more.
