Your father has a request of you

You hear a perfunctory knock on the door and look over to see your father, Sawyer, step into your room. He's a svelte 38-year-old, some white hair beginning to show through his hair and neat beard. "Alex, could you come downstairs for a minute? I have something I'd like to ask you." You get up and follow your dad downstairs to the living room, sitting at the couch across the coffee table from him as he settles down into an armchair.

"It's about your brother," he explains as your hand unconsciously drifts back to your crotch; you pull yourself back and look at your father in understanding. Your younger brother Mike has barely been out of his room since graduating high school, and it's no surprise to you that your father has been worrying. "I don't know why he's been so sullen, but I'm afraid I won't be able to get through to him in this state."

"So you want me to talk to him? He hasn't been talking to me, either," you say in confusion. "I don't see how that'll help."

Sawyer shakes his head. "You misunderstand. I want to brainfuck you and let your brother keep you as a pet. Hopefully, caring for you will get him out of his shell a little, and maybe help him interact with people outside the house."

You gape for a second at your father. "Wait, I don't think-"

He interrupts you, his brow furrowed. "Remember that I am your father, Alex. I intend to do what's best for my family, even if you make me have to brainrape you for it."

You shake your head. "No, no, I'll do it, don't worry. I'm just not sure putting more responsibility on Mike is the way to do this."

Your father nods. "That's a valid concern, but I'm certain it won't be a burden on him. Anyway, as long as you're under my roof I'm still responsible for feeding you, and if Mike doesn't put effort into keeping you his pet you'll just recover and we can try something else."

That makes sense to you, and you get up to move into position for getting brainfucked. "Should I undress now?"

"That's probably a good idea." Your father looks you over appreciatively as you slip your shirt off, pulling his sizable cock out of his pants. "Take it from me, getting someone who's been brainfucked to keep it together long enough to undress can be quite a hassle." You chuckle as you move in, first taking your father's cock into your mouth to lubricate it with your spit. He gently rests a hand on the back of your head, pulling you back before too long. "I think that should be enough, dear, I'd like to save some for the main event. Speaking of which..."

Embarrassed, you turn your head to the side and moan as you feel your ear stretch around your father's erection. The effects are immediate; you feel your surface-level worries slip away as the huge member starts to poke at your brain, precum oozing into your head. As your dad begins to fuck your head more vigorously, the effect ramps up; more and more of your mind starts to fade, leaving you a vapid wreck. This continues for a few minutes; you're dimly aware of a dull discomfort from dripping mound, left untouched as your motor skills temporarily leave you. Suddenly, you feel the continuous hammering stop and hear deep grunting from above you. Moments later, the void left in your mind is filled by an insatiable, gnawing hunger for cock as a wave of splooge bursts into your head, washing away whatever remnants of your intellect were left after the brutal mind-fucking. As a wet pop heralds the removal of the cock from your ear, you blink and look around in confusion as bits of your mind start to resurface, although you're still mainly occupied with a deep need to be filled. After a few seconds, you recognize the man standing over you and immediately brighten up.

"Daddy!" You beam up at your father. "You fucked my brain, right?"

He nods. "Yeah, Alex. Do you remember why?"

You focus for a moment and gasp in recognition. "Yeah! I'm gonna be Mikey's pet!"

He reaches into a pocket and pulls out a leather collar, which he secures around your neck and attaches a leash to. "Right. Now I'm going to go give you to him, okay?"

You nod happily and get up to follow him. You can't wait to be your brother's pet!
