Sorry for the long wait - life got a little busy - and thank you for your reviews and the favorites. It's been ages since I've written more than a one-shot but I simply adore Simon and Isabelle and they deserve their HEA in a more rounded story.

Before you read this chapter please go back to chapter one because I've edited it and added around 200 words.

Hope you enjoy the second chapter of

Training Simon

The next morning the sky is gray with heavy raindrops pelting against Simon's window. Isabelle wakes up, the weak light shining on her black braided hair and making it seem like shimmering silk. She blinks twice before she realizes that she is lying on top of Simon, her legs tangled with his and her head on his chest. His slow but unnecessary breaths ruffle her hair and his hands rest on the small of her back, one of them close to her backside. Isabelle tries to roll out of his embrace but Simon only tightens his grip. "Stay," he murmurs huskily. Her breath nearly hitches but she catches herself. "Wake up sleepyhead; it's time to learn some cool defense moves." Simon groans and flips them over with his nose suddenly buried in her hair, "You smell nice." Isabelle's eyes widen, "Simon…" "Ok, I'm awake. In fact, I've been awake for almost an hour now." She rolls her eyes and tugs on his hair so that he's looking at her. His brown eyes which always remind her of chocolate stare back at her and her heart gives a tiny but not completely unwanted flutter. "You could have woken me up, you know. I'm used to rising early." Simon shakes his head, "No way. You were making these cute noises in your sleep and I liked watching you for a change." Isabelle averts her gaze, "What time is it?" "Almost 7.30." He lets her go and sits up, "You can use the bathroom first, I'll make you breakfast." She nods and gives him a grateful smile, glad that they both are no longer affected by yesterday's sudden awkwardness.

After a quick and refreshing shower, Izzy steps out of the bathroom while opening her braid. She shakes out her hair and approaches Simon who is busy at the stove. His hair is mussed up from sleep and his pajama pants are low on his hips revealing a bit of pale skin between the waistband and his shirt. Isabelle's fingers itch to touch his skin but she holds herself back. "Something smells amazing", she tells him appreciatively. Simon stiffens for a split second and then relaxes again, "Damn, don't sneak up on me." She grins and rests her hip against the counter next to him, "You're just not focused. Once you've had a few training lessons with me, you would have heard me despite the sizzling pan." She pokes his side teasingly before she looks at the content of the pan. "Is that an omelet?" Simon nods and puts it on a plate, "Yeah. We don't have much food because Jordan often leaves without breakfast and I don't need to eat. We just had a few eggs and toast left, I hope that's okay." Isabelle takes the plate, "I don't mind, this looks delicious." Simon finally has a good look at her; her normally straight hair tumbles over her shoulders and her skin is slightly flushed from her shower. She is back in her training outfit which reveals a lot of her runes. He exhales and before Isabelle can sit down to eat her breakfast, her stops her with a hand on her wrist. "I think you forgot something." She looks at him quizzically. "Basia coquum" he says softly. Her eyes widen and her lips part involuntarily. Simon's gaze wavers between confidence and insecurity but before he can retract his bold demand, Isabelle steps so close to him that he can feel her chest rising against his. She gently sets down the plate on the counter to have both of her hands free. One sneaks behind his neck whereas the other rests on his shoulder. She lifts her head, looks at him with so much longing in her eyes that Simon takes a step back and bumps against the stove. His hands come to rest on her waist and then she is finally kissing him. Her soft, warm lips press against his and she runs her hand through his curls. Before Simon can bring Isabelle even closer to his body, she takes a step back and places a final gentle kiss on his lips, "Thank you for the omelet." Simon nods without being able to form any words. He watches how Izzy takes a seat at the small kitchen table where she digs in. He finally clears his throat, "I'm gonna take a shower." Isabelle arches an eyebrow at him but remains quiet.

She continues eating her breakfast and even starts with the dishes before Simon appears at her side again. Izzy bites her lip to keep herself from commenting on his long shower and finishes drying the pan. "The omelet was fantastic. I didn't know that you can cook." Simon shrugs and runs a hand through his damp curls, "My mum often had to work so she taught Becky and me." She reaches out to give his hand a comforting squeeze, "How are things with you and your mum?" He grimaces which makes Isabelle's chest tighten. "We're still working on it but it's slow, very slow." She nods, trying to understand how hard this must be for him but failing. "I hope everything will turn out ok." Simon clears his throat and to prevent himself from saying anything further, he grabs a dish towel and helps Izzy.

Once the apartment is clean, probably cleaner than it has been in a while, Simon and Izzy leave to meet Clary and Jace. They take the subway and slowly excitement starts to grow in Izzy's belly. She takes Simon's hand and swings their hands around. "You're in a really good mood, should I be worried?" Simon asks carefully. She grins and says teasingly, "Maybe." He pulls a face and Izzy quickly amends, "Kidding, you will be fine. Just don't listen to Jace and whatever he says, do not practice with him. If you need a guinea pig you ask me or Clary, ok?" He nods, looks ahead and barely suppresses a groan. Isabelle follows his gaze and her eyes land on Clary and Jace who are kissing in front of the Institute, "Are you jealous?" Simon gently pulls her to a stop and brushes his thumb over the hand he is holding, "No, Clary is happy with him so I am happy for my best friend." Isabelle looks at him searchingly and finally accepts his statement, "Ok, let's separate these love birds. They can make out when we are not present." They arrive at the Institute's gates. Izzy clears her throat and her brother slowly untangles himself from his girlfriend. "Ready to get your ass kicked, Lewis?" Jace asks cockily, his eyes glowing more golden than usual. Clary punches his shoulder and Isabelle glares at him, "The only one who might kick Simon's ass is me or Clary. You stay away from him, Human Torch, " she replies with her hands on her hips. Jace grins, "Relax Iz, I won't hurt your Simon." Simon blushes and Isabelle mutters a "You better not" under her breath. She squeezes his hand and addresses the others, "I'll quickly change into a new training outfit, give me 5 minutes." Simon nods, shuffles his feet and looks a bit uncomfortable to be alone with Clary whose hair is more unruly than usual and Jace who has a very smug look on his face although his skin is rather transparent at the moment. Clearly Clary and Jace have been working on the latter's heavenly fire issue.

Isabelle dashes into the Institute, not willing to leave Simon alone for long and bursts into her room. Despite all the mess, she finds the outfit she is looking for and quickly changes into it. Simon's leather jacket which he has given her the previous evening rests on her bed and although Isabelle has more than enough jackets to choose from, she picks it up again and slips it on. It smells like him and she has to suppress a small sigh. They have kissed – repeatedly now – Simon has drunk her blood which was one of the most sensual things Isabelle Lightwood has ever done and they have a movie date, but are they together? No. She is not sure how much longer she can stand this uncertainty.

Lost in thought she joins the others again and her hand captures Simon's of her own accord. The quartet takes the subway to Central Park and they reach the spot that is glamoured from the mundanes. Isabelle widens her stance and fixes her gaze on Simon who has started to look a bit worried, "Ok, here is what you need to know. You don't need brutal strength or actual weapons to win a fight." Jace nods. "You can use your elbows, knees, feet, hands, even your head." Isabelle touches Simon's forehead. "If you use your head the right way, you can knock your opponent out. Same with the back of your head. A trick that we girls prefer is a good kick to the groin –" Simon and Jace grimace – "Or a kick against the knee, preferably the inside. Your attacker will go down and allow you to have a few precious moments that can be all that you need to escape. Because that's what you want to do, put your attacker out of commission so that you can escape. You don't beat him or her into a bloody pulp, you just get the hell out of there. Call the Institute and we might be able to take care of the rest. Ok?" Simon nods. Isabelle give him a slight smile. "Alright, first Jace and I will show you how to get out of a headlock. Jace?" The golden haired Shadowhunter groans, "You just had to start with that!" She grins, "I'll go easy on you, promise." Jace grumbles and gets behind Isabelle. He wraps his left arm around her neck, his feet set apart for balance. Isabelle's one foot steps behind him, she ducks, kicks his groin, puts her other hand under his nose and presses Jace's head backwards. He falls and lands on his backside. Izzy nods, "Ok, that's one way to do it. When you put your hand right under your attacker's nose, you change their center of gravity. Let me show you something." She waves Simon over to her and puts her hand under his nose, "Try to walk now." Simon takes half a step and then tips backwards. "See? Easy as that. Now, I'll show you another way to get out of a headlock. Jace?" They take their position again and this time Isabelle explains her moves, "Take the hand that is behind your body, put it on the shoulder that is between your heads and just push him forward." She demonstrates and Jace is on the ground again. "Whoever attacks you will be afraid to land on their face so they will let go of you. Wanna give it a try or do you want to see another move?"

Simon opts for another move and Isabelle and Jace demonstrate how to get out of a chokehold. After Jace is once again on the ground, he complains, "I think you're having way too much fun with this, Iz. Let him practice with Clary now."

So Simon and Clary practice the moves, following instructions from either Isabelle or Jace.

The Shadowhunters go through even more defense techniques when Clary suddenly interrupts them, "I'm sorry guys, but I have to leave now. My mum needs me for her wedding preparations." She gives an apologetic shrug. Jace wipes away some sweat and wraps an arm around her, "I'll take you to the subway. Alec has been alone far too long, he needs some brotherly support." They say their goodbyes and then Simon and Isabelle are alone again.

Simon watches how Isabelle brushes away a few damp strands of her dark glossy hair. He inhales and the sweet smell of her sweat hits his nostrils. Her breathing is slightly elevated and Simon has never seen her so alive, so beautiful. He swallows and winces when his fangs pierce his bottom lip. He quickly licks his blood away before he turns to Isabelle, "What now? Are we done for today?" Isabelle chuckles softly, "No, let's go through all your defense moves again and then I'll show you a few others."

The vampire and the Shadowhunter fake-fight and Isabelle is surprised how fast Simon has learned the moves. She praises him for a clever combination of two techniques and finally he manages to toss her to the ground. Simon is leaning over her and his arm is slightly pressing against her windpipe. Their faces are only inches apart and Simon feels how her breath washes over him. His gaze flicks between her parted lips and her dark eyes which stare back intensely. "Good", Izzy whispers and Simon lets go, standing up and reaching out a hand to her. She accepts his help and is now in standing in front of him with a vulnerable expression on her face.

"What are we doing, Simon?" Isabelle asks breathlessly. He frowns, "What do you mean?" "This," she points from her to him and back, "Us, you and me?" Simon's frown deepens and he looks around helplessly, "I'm not sure, Isabelle." She gives a little huff, "Do you like me?" His spine straightens and he looks at her, his gaze filled with emotions Isabelle cannot quite read, "Yes, of course I like you!" She steps closer to him and suddenly he has difficulties focusing on anything else than Isabelle. Her scent lays itself like a blanket around him and Simon takes an unnecessary breath which only enhances everything. Her deep brown eyes stare into his and she quietly murmurs, "I like you, too. In fact, I more than just like you. You are under my skin and no matter what I do, I just cannot get rid of you, don't want to get rid of you in fact. I've never – I've never felt like this before and I'm a bit afraid because my heart feels very fragile around you." Simon pulls her even closer to him and brushes a hand over her cheek, "Are you saying that you are in love with me?" A blush almost explodes on her face and Simon feels her blood warming up her face. Isabelle looks down for a short moment and when she looks up again, she looks like the Isabelle he is used to. "Yes, that's exactly what I'm saying. I'm in love with you," she boldly admits. "Can you now please say that you are in love with me too, kiss me and be my boyfriend?" Simon grins her favorite smile, the one where first one corner of his mouth lifts before the other. He nods and tips her face back, "I'm in love with you, too, Isabelle. I've been in love with you for a while now." She beams at him but Simon quickly covers her smiling mouth with his own. He carefully nips at her bottom lip and when he feels her sink against his body, he knows that he will always remember this training lesson.

The end

I might write a 'sequel' about Simon and Isabelle's movie date that I mentioned in the first chapter.
