You keep quiet.

You manage to swallow back the words, but you can practically feel the words "fuck me" caught in your throat. The need just keeps growing in you, and a guilty part of you wishes Brad would just hurry up and fuck you already instead of this maddening teasing.

"Well, that was fun, but I'm bored now." Brad casually stands up and puts his cock away inside his pants. You try not to be too obvious but you can't believe how big it is, even feeling it slide against your ass, you had no idea you were about to beg for a foot length cock. You consider objecting, but you can't think of anything you could say that wouldn't make you sound like a needy faggot.

Brad leaves and you stare blankly at the porno. You're still so achingly hard. You see the blissful bimbo now stuffed full of cock and you hate yourself for the pang of jealousy you feel. You sigh and shove your puny hard on back in your tights. You know cumming now will just leave you feeling like the limp little loser you are.

...

You spend the afternoon trying to distract yourself and avoid Brad and fail miserably at both. You go to take a cold shower only to run into Brad finishing a hot one, rivulets of hot water running down his glistening muscles, down to his towel hanging so low you can see the top of his thick shaft..."Looking to get steamy, bro?"

You manage to rush back to your room and spend a few frustrating hours playing games. But eventually you need to eat something. You run into Brad in the kitchen. Wearing nothing but a wife beater and boxers, his bulge clearly outlined, his cock hanging so low even soft that you can see the head peaking out from the left leg, "You hungry, little bro?"

You head back to your room, starving for a meal you don't dare acknowledge. You surf the web trying to distract yourself, but you find your search terms getting more and more...questionable. You decide you have to confront this once and for all. You head downstairs and find Brad sitting on the couch, completely naked, watching the same porno you had on this morning. "Hey, bro, why don't you join me?"

You sit as far from your brother on the couch as physically possible, but you can swear you can still feel the heat radiating off him. He sits maddeningly silent, staring straight ahead at the screen while stroking his huge shaft. You try not to stare, but it's so long, glistening with his spit, so impossibly wide. You have to know what it feels like inside you. "So, uhm, would you like to uh, you know, maybe play with my ass some more?"

"Bout time you came begging for my dick, bro. We both know you were practically begging for me to fuck you this morning. Now if you want it, begging's not enough. You've got to kiss it first."

You can feel your asshole quiver. If you do this, you can never take it back. But how long can you go without finding out how it feels inside you?
