“I’m sorry I’m sorry!!” His little brother wails, trying to kick himself away. The little brat used his stuff again. The eyeliner he stole was running down his face as his brother kept him pinned. His hair was a frizzy mess, he had tried to style it like his big brother but only made himself look stupid.
“You wanna use my stuff right? Fucking use it.” He hisses pressing the curling iron down on his brother’s thigh. He holds it there, listening to the sizzle as his brother screams. His back arches and his eyes roll back, even if he’s in pain he looks like he’s having an orgasm. His toes curl in his socks as he tries to push away from the searing pain. 
“I’m sorry! I’m ahh -hic- so-ORRY! Please please take it off!”
He does pull it away, but only because he wants to admire the burn there. It’ll scar. He runs his cold fingers over the hot skin. He’s hard in his jeans now, he shouldn’t be but he is.
“You’re sorry, huh?” He puts the iron down to undo his jeans, letting his hard cock spring free from its confines. “How do you wanna show it? We can keep going with the iron, or you can spread your legs for me.”
His brothers eyes are closed now, sniffling and shaking on the bathroom floor. He doesn’t say a word, just lets his legs slowly fall open. He doesn’t get the kindness of being an inactive participant.
“Like you want it. Or I’ll use that iron to really make you sorry.”
A sob wracks through his little body as he places a hand between his legs to spread his cunt open with his fingers.
“P…please fuck me. I’m so…s…sorry! Please fuck me, forgive me, please please please.”
That’s better. He sighs leans over his brothers body, squeezing his face in his hands.
“You know I love you, right?”
