Gaslit into getting railed

Walter protested loudly, trying to wriggle away from Peter's advancing hips. "Wait, wait, wait! This isn't right! I'm your father, not some fuck toy!"

Peter paused, his cock halfway into Walter's tight ass. "But Dad, you said yourself that you're Kate Upton now. Isn't this what every guy wants? To fuck Kate Upton?"

Jacob chimed in, "Yeah, Dad. You can't blame Peter for wanting to tap that ass. It is a pretty nice one."

Walter looked back at Peter, then at Jacob, frustration and confusion etched on his face. "But I'm still your father! This is ****!"

Peter shrugged, his cock twitching inside Walter's ass. "Technically, you're not our dad right now. You're Kate Upton. And hot-as-fuck Kate Upton just offered her ass up to us."

Walter groaned, a mix of protest and pleasure as Peter started to move his hips, fucking him slowly. "But... but this is wrong..."

Jacob walked over, stroking himself through his pants. "It might be wrong, Dad. But it also feels really fucking good, doesn't it?"

Walter couldn't deny the pleasure coursing through his body. The sensation of being filled, of Peter's cock hitting all the right spots. He let out a soft moan, his protest growing weaker. "Y-yes... but this is just so fucking weird."

Peter smiled, leaning down to whisper in Walter's ear. "Just enjoy it, Dad. Enjoy being Kate Upton for us." And with that, he picked up the pace, fucking Walter's tight ass with long, deep strokes.

Walter's protests turned to moans of pleasure, his body betraying him as he enjoyed the rough treatment. He could feel Peter's hips slapping against his ass, the sound filling the room along with their heavy breathing and moans.

Jacob watched, stroking himself faster as he anticipated his turn. "Fuck, this is hot," he muttered, his eyes glued to the sight of his brother fucking Kate Upton's tight ass.
