Martha becomes a victim to the alien’s curios...

    by: Matt Wii Author IconMail Icon
Xon slowly approached Martha and she failed to notice the alien. With each step, the alien studied Martha more and more. It noticed her long blonde hair that cascaded down her back side, her slender frame, and her rather large ass. Martha’s clothes showed off a decent amount of skin as her butterfly tattoo could be seen on her back due to her black shirt only covering half her torso.

“She looks just like the human in the picture,” Xon said to itself as it thought back to the bikini woman on the poster. The longer Xon studied Martha, the harder its erection grew. By the time Xon was behind Martha, Mark’s former cock was screaming for attention. At this point, Martha could feel someone standing behind her and she turned to check it out. She could only sit there in utter shock as she was scared of the sight she saw, her younger brother standing behind her naked and with a massive boner. Her mouth was wide open as she stumbled to find her words.

“MA~MA~MARK WHAT THE ACTUAL FUCK???” Martha screamed out as Xon was thrown off by the loud screams Martha was making. Xon didn’t understand the words Martha was speaking but noticed the girl quickly try to get up from the bed to run. As Martha began to spin to make her exit, Xon reached out with its new arms and forced her to the bed by pushing her shoulders down. Tears began to roll down Martha’s face as she screamed into the pillow.

“Is this the human mating ritual?” Xon asked itself as it was unaware that it was doing something wrong. Xon sat there and tried to figure out what the next more was. It noticed that Martha’s mouth continued to be open to scream and assumed that perhaps that was the next step. The alien let go of Martha as she quickly spun around, screaming as she did so.

“WHAT THE FUCK ARE YOU TRYING TO DO? SOMEONE HELP ME,” Martha screamed as the alien had an excited look on its human face. It once again pinned Martha down to the bed but this time Martha was facing upwards. Spotting her mouth, the alien assumed this was where it needed to place its new cock. The alien straddled Martha, using its massive legs to hold Martha’s arms down. Martha began to freak out even more than she already was as she realized what the alien was attempting to do. In her mind, however, she didn’t know this was an alien. Instead, Martha believed this was her actual brother who was attempting to fuck her face.

“Please Mark, don’t do this to me,” she pleaded as the alien noticed Martha starting to close her mouth up. Letting go of her shoulders, the alien placed one hand on Martha’s forehead and one on her chin. It then forced her head into the pillow and to open her mouth. Martha could only scream as the alien looked down at her with a massive smile. Slowly, the alien moved its hips until its new cock was lined up with her mouth. Its tip touched Martha’s tongue, something she instantly cringed at.

“This is so exciting. I get to reproduce as a human,” Xon said to itself as it slowly slid its 8 inch cock into Martha’s mouth. Martha’s screams were quickly muffled as the cock hit the back of her throat and slid further down. Martha’s airway was completely blocked as Mark’s former cock went completely into Martha’s mouth.

“This feels extraordinary. Her hole is so warm and wet,” Xon thought to itself as it slowly began to pull its cock back out. During this, the alien noticed how satisfying it was to fuck the poor girl’s throat. After a couple seconds, Mark’s cock was fully out of Martha’s mouth.

“Please Mark, stop this. I’m your sister for crying out loud,” Martha cried as tears rolled down her cheeks. Xon was unaware of pleas for help as it once again slid its new cock back down Martha’s throat. During all of this, Martha tried her best to move her brother off of her. She kicked her legs and wiggled her arms but was unable to do anything as her brother was too strong and too big for her.
