He wants to humiliate you

There's a wicked grin painted on your brother's face, and it warns you about what is about to come.

"Come here John" He mumbles as he leads you towards the closest window, he presses you against the cold glass and positions himself right behind you. You can feel his hot breath on your delicate neck as you hear him unzip his jeans down. "I'm going to show everyone who you belong to." He huffs as he throws his jeans and boxers to the floor, his big cock now brushing against your still covered bottom. As soon as you feel his hands on your own jeans, you know that he is not joking.

"No please, don't do th--" You struggle against him in vain, you never learn your lessons. Ben now holds your face in his strong hand and makes you face him, frowning down at you. "You should have thought about it before lil bro. Take your clothes off, now."

You take a deep breath in and start taking your clothes off, throwing them on the floor one by one. "Good boy, now let your brother fuck that little ass"

Before you can argue, you feel his tip press against your entrance. Fuck, he's so big that it hurts a lot, he must have taken the good qualities in the family when it came to size since your own dick was rather average, but you were still proud of it.

"How does that feel huh?" Ben asks as he buries his cock deep inside of you, you can feel yourself pant heavily and keep your hands against the cold glass for support, you don't even want to look at it now, anybody could be watching you get fucked by your big brother and it would be rather embarrassing.

"Moan for me John, I wanna hear you scream my name, who do you belong to?" He questions with pure lust, his hand now finding its way around your neck and squeezing it gently.
