Styvbröders monsterkuk för stor för min trånga rumpa

I'm not sure how to even begin describing this. My stepbrother has a cock that's just...unworldly. It's not just big, it's fucking monstrous. And I've been caught up in this web of forbidden desire, unable to resist the pull of his sizeable member. It's like a monster, a beast that demands to be ridden, to be taken deep inside me. I've been trying my best to resist, but every time I see him, the urge is just too strong. His cock is a force to be reckoned with, a giant that demands to be filled and fucked. And I can't help but want more, to feel him stretching me wide, to feel his cum filling me up. It's like an addiction, a craving that can't be satisfied. But I know I shouldn't give in, that this is wrong. But oh, how tempting it is...
