Why not?

"Matt don't underestimate her, this girl is though!", you have to admit. A part of you is really curious to see what would be the outcome of such a mismatched contest. How strong is she? It is that true what she said about her ex-boyfriend? Looking back at the confrontation with the thug that you witnessed, the answer is absolutely yes. Matt scoffs with disparage, looking over the thinner frame shape of his challenger. "Allright, kids…", he says, "If it's that what you want...I will seize the opportunity Chris to show you something since you seem so scared by this little girl". Your brother gets to a chair leaning against the wall and lays there his leather jacket, then rapidly takes off his hiking boots and socks. He's wearing only a green military tank top now, which displays his flat and solid upper body, and a casual elastic jeans below. Grace is waiting for him with a tense expression depicted on her face. As soon as her adversary sets his feet on the large space left for the upcoming competition, she raises her guard, bouncing in front of him up and down. Matt is serious and calm. He puts his hands on the hips, almost unflappable, inviting the girl to hit him. Furious at the provocation, the girl throws a fast high kick aimed at his face that gets to a shy from his nose. He dodged it by a hair. The small girl takes a step forward and shouts, exploding a frontal kick to his stomach.

The blow was strong and it would have damaged you seriously, but Matt is way better; the guy sidesteps and avoids the strike, seizing the momentum to catch her opponent's leg under his armpit. "See boy", he explains to you, keeping her left leg tight, "She is hopping on one foot to keep her balance. I could kick her right leg and break the knee. She would have no way to stop me for my legs are longer. Or…", he continues, going forward and putting a hand over her face, "I could just trip this arrogant gal on the ground placing my foot under her heel". Instantly, Grace tumbles over, knocked down by the leg's sweeping that he'd announced. Matt is chilly. "Of course, it's not over yet. How can we round it off? As you can see, I still hold her leg in my hand. And the foot here...no, stay there…", your brother tells to the girl, who's trying to break loose. He casually puts his big foot on her abs, pressing down to hold her still. Indifferently, the guy carries on with his lesson; "The foot in my hand…I can twist it in many ways to put pressure either on the ankle or the tendons". He wrenches her small foot and she howls in pain. Finally satisfied, he lets her go. It's quite impressive how easily he played with her, you think. Maybe you've overestimated and not underestimated this martial beauty. Or maybe this is just what happens when a grown and trained male fighter meets a smaller girl. "What will we dig into from here? Wrestling or striking?".
