The Devilish Girlfriend

Alison, seeing Tim's confusion and amusement, decided to take her prank a step further. She wanted to really sell it and have some fun with him. A devilish idea formed in her mind, and she couldn't resist the urge to mess with him even more.

She turned to face Tim, a wicked smile playing on her lips. "You know, son," she began, emphasizing the word 'son' to drive the point home, "I think it's time we had a little chat."

Tim's eyes widened in surprise and a hint of horror. "Dad? But... but you're supposed to be Alison. Like, Real Alison, I mean," he stammered, clearly confused.

Alison chuckled, enjoying his dismay. "No, Tim. I am your father," she said, channeling her inner Darth Vader. She took a step closer, her voice dropping to a menacing whisper. "And I am altering the deal. Pray I don't alter it any further."

Tim's mouth fell open in shock. "Oh hell no! Dad!? OMG! But... why?" he exclaimed, taking a step back as if he had been physically struck.

Alison, relishing Tim's shocked reaction, decided to push the boundaries even further. She leaned in closer, her voice low and suggestive as she continued her charade. "You know, son, Aruba is going to be quite the adventure for us," she said, a wicked glint in her eye. "I've been thinking about all the fun we can have under the sun—literally soaking up some extra Vitamin D."

Tim's face flushed a deeper shade of red as he began to understand the implications of her words. "Dad, please don't," he pleaded.

Tim's mind raced as Alison mentioned "Vitamin D," the implications of her words sinking in like a punch to the gut. He pictured a scene that was both obscene and confusing, his imagination running wild with the suggestion.

He envisioned Alison—no, wait, his dad Walter posing as Alison—in the middle of a chaotic gangbang on a sunny beach in Aruba. Multiple men surrounded her, their bodies glistening with sweat and sunscreen. The scene was a blur of moving limbs and moans of pleasure. Tim's stomach churned as he tried to reconcile the image of his father in such a situation.

In his mind's eye, 'Alison' cracked a dirty joke, her deep voice booming over the sounds of the ocean and the occasional laugh from the men involved. "You know, boys, size does matter," he heard his transformed dad say, a wicked grin on her face. "And I've got the biggest fucking D in Aruba!"

The men around cheered and jeered, their voices a cacophony of lust and amusement. Tim watched in horrified fascination as her joke was met with enthusiastic agreement, the men high-fiving and slapping each other on the back.

But the scene didn't end there. Almost instantly, 'Alison' dropped to her knees in front of one of the men, her hands already working to unbuckle the guy's belt. She took the man's length into his mouth without hesitation, head bobbing up and down with practiced ease.

Tim felt a wave of nausea mixed with a strange sense of arousal. He couldn't believe he was imagining his own father like this, but the scene was too vivid to ignore. He shook his head, trying to clear the obscene images from his mind, but they lingered, taunting him with their explicit detail.

"Tim? You okay?" Alison's voice cut through his reverie, concern lacing her tone as she noticed his flushed face and distant gaze.
