Isaac's heart beats like crazy as Stiles gets close to him.

He closes his eyes and puts one hand awkwardly on Stiles' shoulder as the kiss seems to last longer than a truth-or-dare-kiss should, but Isaac doesn't really care because Stiles' lips feel amazing

Isaac: Um...that was actually my first kiss!, he says with flushed cheeks as they pull apart

Isaac: Really? I've never done it before!, he says and smiles brightly as he thought he would totally suck at his first kiss

Isaac: It felt really good, now I know why people do it all the time!, he says and chuckles

Isaac: Dare!, he then says, feeling braver now

Isaac's smile fades away as he looks at Stiles nervously. He thinks about all his scars and bruises but guesses that he can trust Stiles

Isaac: Okay, but you can't tell anyone what you see. Okay?, he says and smiles faintly as Stiles only chuckles, thinking that Isaac's joking.
 
Isaac takes off Stiles' plaid shirt and then his own t-shirt, revealing the huge deep purple bruise that stretches over his stomach, more bruises dotting his torso everywhere, scars that look like they come from a knife, some burns that seem to come from cigarettes and many more
 

Isaac nods and grabs his shirt as he's about to put it back on

Isaac: He drinks a lot and gets mad for everything. I know, it looks ugly!, he says, fumbling around with his shirt to get it on the right side

Isaac gets a bit scared when he thinks about telling Stiles' dad

Isaac: I don't know. You think your dad will care? You think he'll want to help me?, he asks, not used to anyone caring about him
