Adam reaches home(Adam's perspective)

Adam gets out of his car, carrying along the bags of clothes in his arms. He found that the front door was unlocked, which meant that either his sister or mom was home.

"Hello? Sarah? Mom? I'm home." Adam announces as he enters the house.

"Ok, bro. I'm in the shower right now. Be down there soon." Adam hears his sister's voice from upstairs.

Adam carries his stuff up to his room and thinks about what he should do now. Now that his sister was home, he had to find a way to explain his massive transformation to her. Even though he was sure that his hot, and sexy sister would not question it much if he simply whipped out his new monstrous shaft in front of her, it was just irresistable. The thought of **** being wrong was thrown out of the window in Adam's mind, he didn't really care which girl it was, he only wanted to find more willing cocksleeves for his monster. His sexual morals were completely gone.

Before going any further, he decided to take a closer look at the literature that he got with the bottle of Growth X, the pills that had completely changed his life.

"Warning: Take one capsule only , by mouth, daily until desired effects are reached" Adam chuckled while reading that as he had downed the full bottle, completely unheeding the warning, not that he regretted it though.

"Do not take more than one pill within 24 hours, doing so may result in permanent increase in libido" Again, it didn't seem like a bad thing to Adam, he had taken all 20 pills and was pretty sure his libido was through the roof.

"Other side-effects may include permanently increased sexual stamina, permanently increased semen and sperm production, greatly enhanced and accelerated testosterone production and possible loss of sexual morals. Consume at own risk." That explained a lot of things, Adam thought. Again, they didn't seem like bad side-effects.

Satisfied about learning more about the Growth X, Adam decided that he won't hold back his urges anymore. Emily was on her knees for him, so would every woman he wanted, and right now he wanted his smokin' hot cheerleader sister, his cock had started hardening slowly.

He took off his clothes, and entered the bathroom, he saw the silhouette of his sister beyond the misty shower partition. She had not noticed him enter.

He merely waited outside, and it was not long before his sister exited the shower, a towel wrapped around her body and another around her blonde hair, there was enough cleavage of Sarah's C-cup breasts for Adam to feast his eyes upon, along with her curvaceous body.

"Ahhh, WHAT THE FUCK! WHO ARE YOU?!" Sarah screams and backs away, holding her towel tightly, as she sees the tall, hulking, naked man in the bathroom with her.

"Hey, Sarah. It's me, Adam. Don't you recognize your own brother?" Adam replies barely holding back a chuckle. He had changed so much, that Sarah had not even recognized him at first glance.

"A-Adam?! What the hell happened to you? Is this a dream? Did I fall asleep in the shower?" Sarah asked, flustered after finally recognizing the face of her brother.

Adam couldn't help but laugh at her sister's reaction, "It's really me, Sarah. I just went through some 'changes'. And I assure you that it's not a dream."

But Sarah didn't reply, she looked as though she had seen a ghost, but in reality she had caught sight of Adam's semi-hard monster cock slowly rising and throbbing, jutting out from her brother's crotch in front of her.

Adam smirks and takes a few steps torwards his sister, who stands there like a statue staring at his dick, his phallus soon reaches it's full, veined glory of 16.5 inches of pure, pussy-destroying fuckmeat. It angles upwards and throbs hard, a pearl of pre-cum forming at it's tip, which suddenly shoots out a big glob of it towards Sarah's face. She catches most of it in her mouth and stumbles backwards in surprise, her towel falls in the process, completely revealing her body in front of his brother.

Adam takes in the sight of her naked sister, she looked gorgeous, and that would be an understatement. She had a curvy hourglass figure, with long, shapely legs, her midriff was nicely toned due to her cheerleading practice, her shaved pussy which already seemed to be dripping and quite wet and her perky boobs, tipped with sweet pink erect nipples jiggled as she stumbled backwards. Adam's cock throbbed appreciatively and let loose another glob of pre-cum that landed on Sarah's face.
