Mark and Barbara had been recently engaged. They were living in a nice, suburban house. A new, young couple, headed straight towards creating a beautiful family.
He owned a relatively big-sized business, and worked diligently and hard for it to prosper, while Barbara had an office job that meaningfully contributed to society.
It was a warm summer, most of the days were very pleasant. The temperature didn't get too high, and the air didn't get too dry nor too humid. On one fateful Wednesday, Mark was sitting in the living room of their house.
It was spacious and beautiful. With a big plasma TV, an expensive looking bookcase, a minibar in the corner. A wide dining table, many chairs. As well as a set of a high-end couch and two matching armchairs, facing the TV.
And then Barbara came to him with surprising news.
"Sweetheart, I, uhm..."
"Yeah? What is it?" he asked, looking up at her as he sat on the couch.
She appeared...distraught. Scared, even.
"I don't know how to tell you this but, uh, my sister is going to stay with us for a few days."
"Wait, hold on. Sister? Mark asked, perplexed. "I didn't know you even had a sister!"
"Because I didn't want you to know she existed. I... I don't want her in my life," Barbara said, coldly and a little fearfully.
Mark raised his eyebrows quizzically. It was uncharacteristic of his fiancée, she was usually kindhearted, nice, and upbeat. Not scared and angry like that. What was their issue? Sibling rivalry? Was she ashamed about something?
"Sounds like, uh, you hate her," he stated, trying to make it sound mild.
"Yes, I do. You have no idea. She's a nightmare."
There was a long pause.
"And?" Mark broke the silence, curious. "You're not going to elaborate?"
"I can't, I really can't," Barbara said pleadingly. "Please, just trust me."
"Ok...but why is she staying with us then? And why didn't you even ask me?" Mark continued. He would be supportive, of course, but couldn't help but be slightly annoyed. "I'm not exactly thrilled to have a surprise guest, out of nowhere, and without having a say in the matter."
"I'm so sorry, baby," Barbara apologized, her voice trembling as she sat down next to him snuggled up to her husband-to-be. "I'm so sorry, but I have to let her, I have to and I can't say no, and I...I..."
Seeing she was seemingly at the end of the ropes, close to the point of tears, he relented. He didn't understand it at all, but he still loved her. He would trust her if she needed him to.
"Okay, okay, fine. There, there," he said gently, hugging her. Like a dutiful partner providing her with a shoulder to cry on, to share her burden. "It'll be alright, we'll manage. I'll help however you need me to."
Barbara melted in his embrace, trembling yet quickly calming down due to her wonderful man's presence.
"Thank you, and I'm just so sorry..." she whispered.
"It's okay," he cooed, his hands rubbing her back. "When will she arrive?"
"She said on Friday, later in the afternoon..."

The dreaded day came soon enough. Mark didn't really feel bothered, just wanting to get it over with. His fiancée, however, was walking on pins and needles since morning, probably also having caught little sleep in the night.
It was indeed late afternoon, almost evening. The lovely couple were sitting together in their living room, watching TV, when the doorbell suddenly rang.
Barbara instantly got up and almost ran to the door. Mark also stood up and followed, but far more calmly.
He had yet to walk past the corner to see the door when he heard their guest.
"Wooow, nice house! How did a dumb bitch like you get to live in a house like that, huh?"
Mark almost stopped in his tracks, stunned and shocked.
"Um, thanks Pam," Barbara replied, meekly.
He was shocked yet again, and then he stepped in sight.
"Hey, guys," he opened with, but then froze, yet again, when he saw Barbara's sister.
The fact they were related was obvious enough, even though the familiality and resemblence was subtle and in the details. And yet, at the same time, it was beyond surprising.
Because their very feminine guest was not in a different league than Barbara - she was in a different sport altogether. It was unbelievable how much more beautiful she was.
Lustrous blonde hair, gorgeous face of a supermodel, sharp makeup, and a body straight from a wet dream clad in a size-too-slim pink T-shirt with a valley of cleavage and skin-tight blue yoga pants.
She was clearly fit as hell, with sexy, taut abdomen and oh-so-slim waist and curvy hips that brazenly boasted about her perfect hip-to-waist ratio. And, to top it all of, she had huge, juicy, and almost unbelievably perky tits.
With the attitude that he had just heard a hint of, there was no doubt she was more than a big handful...in several ways.
"Oh!" the beauty exclaimed in surprise. For just a moment, however, as her voice soon turned sultry and her pouty lips curved in a strange smile. "Hello indeed...who might you be?"
Mark saw, and felt, what happened next - how her eyes dropped and slid up and down his body.
Now, he wasn't a bodybuilder or nothing crazy like that, but he did workout hard and regularly.
And Pamela immediately noticed.
"I'm Mark, Barbara's fiancé. You're her sister, I'm assuming?
"Mmmhm," she hummed, still smiling strangely.
There was a tiny bit of pause. His fiancée did not seem eager to join in, either.
