Sister Incest 4: Turning My Sister Into A Dumb, Blonde Bimbo

by Velvet Diamond

I couldn't believe she fell for it! My 18-year-old sister, Kimberly, drank down my "intelligence" potion like it was a special magical drug that would actually make her smarter.

Unbeknownst to her, it was just the opposite. It was a bimbo drug. And now, my high achieving, college-bound sister was going to be as dumb as a dog.

And I was going to take full and complete advantage of the situation.

Excerpt:

I couldn't believe she fell for it! My 18-year-old sister, Kimberly, drank down my "intelligence" potion like it was a special magical drug that would actually make her smarter.

Unbeknownst to her, it was just the opposite. It was a bimbo drug. And now, my high achieving, college-bound sister was going to be as dumb as a dog – no offense to dogs.

And I was going to take full and complete advantage of the situation.

The change was immediate. Kimberly went from being able to form complete sentences to barely being able to talk at all. It was actually shocking to witness the change firsthand. Not only did she become dumber than a brick, but – just like in them dirty erotica stories – her breasts grew to the size of melons.

Kimberly hadn't actually been undersized in the breast department, but now it looked like she was sporting a watermelon under her shirt. Was actually quite comical and…if I'm being honest, and I am, very hot.

I was extremely grateful that mom and dad were away for the weekend – otherwise, there would be questions. Many, many questions.

Of which my sister – my dumb, innocent sister – would not be able to answer any of them.

"Ugh!" Kimberly raced into my bedroom, comically waving her arms around as she tried to speak. It was quite comical watching her face turn bright red as she tried to form the words that may or may not have been in her mind.

"What is it, sis?"

"Ugh!" She stamped her feet on the ground as she ripped off her shirt and bared her watermelon-sized breasts at me.

I clapped at her. "Good job, sis! You've done what every woman in the entire universe longs to do." I stared at her melons for so long, her cheeks turned red. "Now run along like a good little bimbo and try not to get into too much trouble."

"Ugh! Ugh!" She shook her now platinum blonde hair violently as her face reddened.

"What is it now, sis?" I laughed at her obvious discomfort. "Use your words..."

Sis actually growled and hissed at me. Maybe those are her words now? Was I going to have to start learning Bimboese?
