If you haven't read the first three parts of the story yet I recommend you do so first to understand the history of the developing dynamic between Beth and Marc.
*
"Hey Marc" a voice called out "how are you doing today?"
Marc turned to see Julia walking towards him. Tall, blonde and beautiful she was the type of girl he was always happy to have a conversation with. "Not bad thanks, glad I called it a night when I did. How about you?"
"Same. I left shortly after you did" she responded, "I couldn't even manage to get a room in this hotel, so I was staying at the Regent next door".
Marc gulped a little. He was pretty sure that was the hotel directly opposite this one, the one in which he had seen that distant familiar figure last night as he was fucking Beth against the window of her room.
He scanned Julia's face for any signs that she knew what he was thinking but her expression remained neutral.
"Make the most of the day" she called out as she made her way to the front of the auditorium "it's back to the office tomorrow".
'Surely she didn't see anything' Marc thought, he was just being paranoid. But he couldn't keep the thought out of his head all day long.
Hours later when the formal part of the conference had wrapped up the whole group headed out for a few drinks, pleased that the lectures had come to an end and determined to enjoy the open bar tab that the company had put on.
Beth found herself sitting next to Julia who tried to strike up a conversation about some of the more interesting sessions from the conference and how they might apply the learnings back in the office.
Beth was a little distracted, replaying memories from the evening before in her head and sneaking glances at Marc to see if he was doing the same. The way his tongue had dipped in and out of her, how his cock had filled her pussy, how he'd exposed her to the world...
Julie obviously sensed her distraction as after a time her hand fell lightly on Beth's arm. "I've always admired you Beth" she started "you work hard and get what you want".
The physical contact brought Beth back in to the moment. "That's lovely, thanks Julia. I feel the same about you" she replied feeling a little uncomfortable about this colleague she barely knew touching her arm.
"Well..." Julia continued, "I don't always get what I want".
"Oh, really?" Beth questioned innocently "what do you want that you haven't gotten? Perhaps I can help you". Beth considered herself an advocate for women in leadership and did what she could to help her younger female colleagues achieve their goals.
Julia turned her head and gestured with it to indicate what she meant. Beth followed her gaze across the room until her eyes set upon Marc. He stood tall within a group of guys, his light blue shirt rolled up to the elbows showing off his muscular forearms. He was grinning as he told them some sort of entertaining story, his boyish charm showing through his dimpled smile.
"Marc? You want Marc?" she asked surprised.
"Yes. It's stupid right?"
"Not stupid, just a little unexpected."
"So can you help me?" Julia asked.
"Well, not really, I don't really know him that well" Beth lied, trying to forget about how she had tasted every inch of his body the night before.
"I don't think that's quite true" Julia responded "I actually think you know him very well...intimately in fact...". She said the last part provocatively with a smirk.
Beth sat in stunned silence not entirely sure what to say next. Had Marc said something to Julia? She was going to kill him if he had.
Amidst the silence Julia reached into her bag and drew out her phone. A few taps later she slid it across the table and Beth gasped as she saw what was upon it.
The image was grainy for sure, the camera had been zoomed right in and it was dark but there in the centre of the screen was her naked body pressed up against the hotel window and Marc behind her, gripping her waist as he rammed in to her.
Beth's usually pale skin turned even paler, and her wide eyes filled with panic.
Julia didn't let her sweat for long. "Don't worry" Julia said "I'm not going to use this to blackmail you, even though I probably could".
"Oh thank you Julia, thank you so much" Beth cried reaching out impulsively to hug her against her natural instinct.
As Beth embraced her Julia whispered in her ear "But I do still want Marc...and you too".
Beth pulled back from the hug, head tilted and looking at Julia's face to see what she could gauge from her expression. This woman was brazen, did she really just suggest that? She looked serious.
"I'm bored Beth. You know what it's like working here, doing mindless, meaningless work 40 hours a week. This is not what I thought life would be. I can tell you're bored too."
Julia was a few years younger than Beth and clearly had a wild streak. There was a slight 'I don't give a fuck' rebel vibe to her that Beth secretly admired. Beth didn't know a lot about her other than her adrenaline junky nature -- always heading off mountain biking or snowboarding -- the type of girl that could not only keep up with the boys but actually show them up.
She also happened to be obscenely hot. She had long, wavy blonde hair and green eyes that sparkled with fun. Whenever the inappropriate workplace game of 'who would you fuck in the office' came up she was almost always in the top 5, even for the women.
Beth didn't really have much experience with other women but if she was going to try then Julia would be the sort of girl she'd want to do it with. And Julia was right, her life could do with being spiced up a bit. Her rendezvous' with Marc had injected a new lust for life within her and unleashed a darker, dirtier side that she knew existed but had long kept buried.
Meanwhile Marc was watching the scene unfold across the room with a growing sense of unease. He was sure Beth and Julia didn't normally interact this much and given his own encounter with Julia earlier he feared there might be more to it.
Still, he couldn't help but appreciate the view of the two of them together. Beth dark haired and petite, Julia blonde and athletic, both of them attractive in their own way.
The two girls soon approached the group that Marc was standing with. Julia spoke up "I'm going to take Beth back to the hotel, she's not feeling so good. You guys enjoy the rest of the night".
It was certainly a believable story given Beth's face definitely looked paler than usual but something in her eyes was signalling to him that this was not the whole truth.
Sure enough a few minutes after they had departed he felt his phone vibrate. Sneaking a quick glance away from his colleagues prying eyes he read the message from Beth.
'You've still got the keycard. I suggest you use it'.
He made his excuses as quickly as he could and raced back to the hotel and that room on the tenth floor. The thoughts of what might await him were invading his head the whole way back. Entering the room to find Beth naked and willing to do whatever he wanted the night before had been mind blowing. Was it too much to hope for a repeat?
Upon entering he was only partially surprised to find that Beth was not alone and that Julia was there with her, sitting beside her at the foot of the bed. Both women had a glass of red wine in their hands, Beth's was nearly empty and the slightly perplexed look she wore on her face as she left the bar remained.
He paused in the entryway. He wanted to understand what exactly was going on but there wasn't time to ask as Julia had already confidently crossed the room and had placed her hand on his chest. With her other hand she beckoned Beth to join them.
Beth demurely walked over to them and shot a half smile at Marc that seemed almost apologetic as if the surprise was a bad one.
"Julia knows about us" she attempted to explain "and she wants to join in".
Marc's heart raced in his chest and a small part of his brain went fuzzy and numb as the realisation of what was happening set in.
