HP as a girl... Dudley sub (Patreon)

"Shut up."

Dudley's eyebrow raised as he didn't notice Harry coming down the stairs. She stops watching her bullying, her dom, and her daddy having Petunia on her knees. Petunia doesn't look back acknowledging her presence. Dudley speaks calmly despite momentary frustration simmering below his surface exterior. "What do you think Harry? Should I shut mum mouth for a while? Give her what she deserves for nagging my ass endlessly."

Petunia's scornful expression morphs quickly into a horrified shocked state. She sees Harry's feminine form. Not understand how the former Potter got turned into this. She thought it must be true. The green eyes. She had never seen anyone besides Lily and Harry with those large vivid green color, luminous eyes. She stares back at Dudley knowing what has been happening ever since this girl popped up.

"I believe that best approach sir," Harry responds grinning. She wants to watch the destruction of her former aunt.

Dudley chuckling. "Good girl. Now, Petunia, I hope you are prepared for this huge load coming your way." Brought out his bully cock stroking already leaking cockmeat inches away from Petunia's soft lips.

She pursed her thin nonexistent lips looking at the much larger cock than her husband. Unsure what to do, Petunia opens her mouth gingerly wrapping her lips around his shaft tip cautiously, hesitantly sampling Dudley's unique taste profile. Harry giggled enjoying the event unfold before her eyes. Petunia swiping tongue gathering previous cum residue from recent fuck sessions. His taste caused a vivid gag on her.

How does Dudley fuck her?
