You're far too excited not to

You rush to your room and gather up everything you need, heading to the bathroom to start 'preparing'. You've used a dildo to masturbate often enough that the whole process of cleaning and lubing yourself up is almost routine.

In a matter of minutes, you're ready to get fucked. In fact, you've never felt more ready for anything...you're practically shaking with excitement. You leave your pants on the bathroom floor as you start make your way back to Arya's room, wearing just your shirt.

You're intercepted partway there by Arya, who is in a similar state of bottomless attire, every step making her slightly softened cock bounce about in a very distracting manner. You pause, wondering why she left her room before you got there. Even if your mother is at work, it feels a bit odd having both of your run around the house without pants like this...

Upon spotting you, Arya motions to your room, walking towards it as she does so. "Change of plans, we're going to do this in there." The newly found...contempt is still strong in her voice. You follow along, pulse racing as you grow closer and closer to 'the act'.

Before you can even think to ask why the change of location is happening, Arya answers, whilst in the middle of opening the door and stepping inside.

"If you want to know why we're using your bed, it's because I realized how much your little dicklet will be squirting while I'm using your hole. I don't want my sheets covered in your jizz."

You flush with humiliation at the brutal words - and their obvious meaning that it's fine if your sheets get jizzed on - , only the all-encompassing desire to get fucked keeping you from snapping back...you'll really have to try to recover a bit of brotherly respect...somehow...later...
