The two brothers look up from the bed where they're fucking to see both of their furious parents.
"I...I can explain..." Kenneth says, still balls deep in Max's ass.
"I'd love to hear this," their father, Dave, says. But his subtle adjusting of his pants catches Kenneth's eyes. Max, still gaged and of course limbless tried getting Kenneth's cock out of his ass, but was held in place.
"Listen. Max got into his accident because you wouldn't accept him for being gay. He wasn't joy riding. He was driving in anger." This was all a lie Kenneth was making up to justify raping Max. The anger in their parent's faces turned to guilt instead. Kenneth was turning this around on them now. "He's been pent up and horny, but having no way of giving himself relief. And he can't exactly go out on dates anymore. So I thought I could be his master."
"Master? You mean boyfriend?" Their mother asked, her interest peeked despite the taboo.
"No, master. Max here is a submissive. A bottom. A masochist." As he spoke, he began to get hard again and began fucking Max all over again, right in front of their parents. Horrified, Max tired to protest his brother's lies, but involuntary moans escaped his gag, and his limbless thrashing just looked like writhing in pleasure.
"That all used to just be a small part of his sexually," Kenneth says, breathing heavier as he picked up the pase. "But now that he's helpless, he's completely given into this sissy bitch side of himself. He can't go to university, he can't get s job, he can't play video games or go out with friends. This is all he's good for anymore, and he desperately wants to be able to live as our humiliated sex toy."
Max cried out against the lies and humiliation, as his brother hit his prostate again and again. Their parents could just watch in astonishment at how much he apparently loved being used and abused this way. Max wanted to tell them it wasn't true, but something about the situation was resonating with him somehow. Even if he wasn't gaged, thanks to his brain surgery, talking was impossible for him.
The orgasm came unstable. Max moaned like a bitch in heat as he proved to his parents what a bitch slut he was. Kenneth also came, filling Max up for the second time in a row with incestuous juice.
Kenneth pulled out and undid Max's gag. Then scooped up Max's cum from the limbless boy's chest and fed it to him. Max was in such a dazed space that he simply accepted it, licking his brother's cum covered fingers clean.
"This is a lot to take in..." David said, glancing at Max with hunger of his own in his eyes.
"This is a big lifestyle choices. Maybe we should sit down and talk it over."
"Let's let Max rest. He's been through a lot. I know him better than anyone and have had a lot of time to talk with him. He can't speak, of course, but we have a deep connection, so I can facilitate communication on his behalf."
"Good. We've got a lot of questions. Put on some pants and come down to the living room to discuss how we should treat Max from now on."
