Knock, knock, knock.

“Greg, can you get the door!” Greg’s girlfriend called from the kitchen.

Knock! knock!

“Greg!”

Greg sighed as he minimized his computer browser and put the keyboard drawn in. “What?!” he yelled back at Bethany.

“Get the door…”

Greg walked down the stairs and opened the front door. Standing there was Bethany’s younger sister, who was holding a suitcase in front of her.

“Aren’t you going to invite me in?” Peggy asked as she moved the suitcase to her side, revealing a pregnant belly.

Greg gave Peggy a confused look as to why she was here and why she had a suitcase. “I’m sorry, were we expecting you?” Greg asked bluntly. “I don’t recall Bethany saying anything.”

“No you weren’t expecting me, nor were you expecting me to be expecting,” Peggy said as she moved her suitcase to the side, revealing she was heavily pregnant.

Greg looked at Peggy in disbelief. “I… don’t understand.” Was all he could mutter. He could’ve sworn he had only seen Peggy a few months ago and Bethany certainly didn’t mention her sister being pregnant, at least he doesn’t think she did. He was also certain hearing something about Peggy being gay.

“Who is it, Greg?” Bethany called out.

“It’s your sister…. and she’s pregnant…” Greg said without thinking.

Greg heard glass shatter as Bethany ran from the kitchen to the front door. “What?!” She exclaimed, seeing her pregnant sister.

Greg looked at the two sisters and thought it best to leave them to discuss the situation. So he went to head back upstairs.

“When did this happen? How did this happen? Why didn’t you tell me?” Bethany was still gawking over the situation as Greg returned to the study.

“What are you waiting for, an invitation, come in already,” Greg heard Bethany say as he sat back down at the desk and put on his headphones.

Greg was browsing the internet, listening to music, when he was startled by a tap on his shoulder. He jumped and quickly close down the web browser and muted the music as he turned around to see Peggy standing there.

“Sorry to interrupt but would you be able to bring my case upstairs?” She asked politely.

Greg still wasn’t sure what to say to her and so he just nodded and went downstairs, making a detour to the kitchen first. “I still can’t believe Peggy turned up out of the blue like this,” he vented to Bethany.

She just gave him a funny look. “What are you talking about, I told you this morning that her boyfriend dumped her and she was going to be staying with us until the baby was born,” Bethany scoffed as she resumed working on dinner.

“You’re screwing with me right? A minute ago you didn’t even know she was pregnant,” Greg shook his head.

“I’m pretty sure my sister would tell me if she was pregnant! Why are you acting so weird?”

“Me? What about… ah forget it,” Greg knew he wasn’t going to win, even though he knew he was right. The girls probably decided to play a prank on him and he couldn’t be bothered to play their little game. So he left the kitchen grabbed Peggy’s suitcase and returned to the study / guest bedroom.

“Aww that’s a relief,” Greg heard Peggy sigh as he walked up the hallway. “All that extra weight was killing me.”

Greg entered the room and froze at what he saw. Peggy was in half with her pregnant lower half laying on the bed while her torso and upper half were sitting up.

“Oops, I guess I forgot to shut the door,” Peggy facepalmed. “I guess this is a bit more of a surprise than discovering I was pregnant, huh?” She gave Greg a polite and awkward smile. “Don’t be shy, I’ve seen your browsing history, I know you want to see this,” she said tapping where she had been separated. “Just shut the door on your way in, I don’t want to ‘explain’ this to Bethany too.”

Greg was red faced at hearing Peggy knew about his internet history. He nodded to Peggy and stepped into the room, shutting the door. He slowly made his way over to Peggy and saw the smooth skin atop her lower half for himself.

“Pretty cool huh, want to feel what it’s like?” Peggy asked. Greg still couldn’t say anything and just placed his hand on her smooth flesh. “Aww that’s cute but that’s not what I meant,” she said with a devilish smile.

Peggy then wrapped her arms around Greg and pulled him upwards, splitting him in two. She couldn’t hold him for long and ended up dropping his upper half, making him fall on the floor. As Greg lifted himself up with his arms, he reached for his own legs but Peggy had already grabbed them and attached them to herself.

“Someone’s a naughty boy,” Peggy teased as she put her hands down her new pants, feeling Greg’s penis. “I’m not sure Bethany would be pleased about this,” she commented as she picked up her pregnant half off the bed and attached it to Greg. “Getting aroused by his future sister-in-law’s pregnancy, so much so he had to take it for himself, even if it meant giving up his manhood. It’s going to break her heart.”

“What?” Greg asked as her turned around to see his new belly. “Oh my god, what did you do?” He cried out, looking up at Peggy who had just left the room. “Wait… no!”

Greg struggled to pull himself up from the ground, feeling the strange weight. He took a step forward and stubbled. It took him a second to find his balance before chasing after Peggy and stop any damage she might cause to his relationship with Bethany. Though he found walking awkward enough as it is, not used to the pressure being placed on his lower half, yet alone wearing a skirt.

When he finally made it downstairs he found Bethany and Peggy in the living room, with Peggy crying his eyes out. “He stole my baby and turned me into a freak, what kind of person does that to someone?” Peggy sobbed, laying her head across Bethany’s lap.

Bethany looked up to see Greg standing there, staring at him with furious eyes. “What the fuck is wrong with you?” She screamed at him. “Fix this right now and get the fuck out of my house, you sick… sick…” she couldn’t even come up with the words to describe what she thought of him.

“I’m not the one who did this, Peggy did. I don’t know what she is but your sister isn’t normal. She did all of this, she must’ve even made herself pregnant, as she sure as hell wasn’t last time we saw her.”

“Of course Peggy isn’t normal, because you stole her entire lower half. I’d cut off your dick if you hadn’t given it to my sister!” Bethany had already decided who was in the wrong.

“Don’t anger him sis, if he did this to me, I’m scared what he might do to you,” Peggy pleaded.

Before Greg or Bethany had time to respond to Peggy’s comment. Bethany’s body fell to the floor, sending her head rolling across the room.

“What have you done to me?” Bethany asked in fear. Greg picked up head head and showed her her headless body. “Put me back on my body right now!”

“I didn’t do this, it was Peggy. You’ve had your fun now tell her the truth Peggy!” Greg demanded as he placed Bethany’s head on the coffee table. “Tell her the truth or I swear… I’ll…”

Greg stopped in mid sentence as he watched Peggy’s mouth vanish, leaving a blank patch of skin between her nose and chin. He then saw the look in her eyes change as she stared at him and Bethany.It was a mix of fear and confusion, she wasn’t the same person she was a moment ago. Her eyes were locked on Greg’s pregnant belly and lower half. She then turned her attention to her own lower half and Greg swore he heard her scream.

“Peggy is that you?” Greg asked. She nodded. He pointed to his belly. “This isn’t yours is it?” She shook her head. “How did this happen?”

Peggy looked like she tried to say something before realising she couldn’t so she reached down for a piece of paper but before she could grab it, her arms vanished.

“What the hell is going on!” Bethany exclaimed.

“I think your sister was possessed and whatever it was did this to us,” Greg stated, still trying to wrap his head around it.

“Wait where’s my body?” Bethany realised. “It was here a second ago.”

Greg went to look for it, when he heard the front door open. He managed to make his way out, just in time to see Bethany’s headless body pulling out of the driveway in Peggy’s car. On the ground he saw a note: ‘Thanks for letting me be your guest’

Whatever that thing was it had gone now, leaving the three of their lives forever altered. If Peggy could communicate she would tell them how there was a fourth person changed by this, and he was currently resting inside Greg’s pregnant belly, where he’d remain.

An hour later Greg received a text message from his cousin informing him that Bethany’s body just showed up at her door. When he tried to call her back she didn’t answer.
