All three people were frozen in place.
Susan continued to stare at the naked couple with her eyes and mouth wide open. Martin still had his withering penis lodged in Theresa's tunnel. He looked over his shoulder to the HR director and had no words to say. Theresa lay with her legs splayed wide. She was mindful of Martin's cock shrinking while his cum-shot drooled out of her slit. None of them were capable of doing anything but staring at each other in shock.
After a long time, Susan cleared her throat and looked to the floor.
"Um, sorry to interrupt," she stammered nervously, "I was, I mean, I came to see if you were gone yet."
"Uh-huh," Martin muttered nervously, "I um, we were just--."
"I know what you were doing!" Susan blurted, "I, well. Whatever you do, it's none of my business!"
"Uh-huh," Martin repeated in a daze.
"Just tell me please!" Susan said, "This was, um, consensual?"
"Oh yes!" Theresa exclaimed, "If it was anyone's fault, it was mine! I was the one, I mean, Martin would never have even looked at me if I--."
Susan nodded with her face still flushed beet red.
"Okay!" she said, "That's all I need to know!"
Martin and Theresa still stared toward her, and she swallowed nervously. She was not aware of it when her hands cupped her large boobs and squeezed softly.
"Well!" she said, "I guess I'll just, um, see you Monday!"
She walked quickly toward the door to the other wing and stopped. She was breathing heavily and the sight of the couple on the couch refused to leave her mind. She could still see them, Martin on top thrusting into the younger girl. Theresa with her arms and legs passionately wrapped around him.
"Wow!" she breathed, "It's been so long!"
She began to think about the last time she had sex. It was a long time ago! At least six months! Watching them had made her soaking wet!
"I never even imagined Martin that way!" she muttered.
Again she saw his erect cock sliding in and out of the other girl.
"She seemed to be enjoying it!" she whispered.
Susan crept into the corridor leading toward the bathrooms and peered back toward Martin's office. She wanted to see if they would continue making love or if they would dress and scurry out of there.
"Oh my God!" Martin moaned, "This is a disaster!"
Still naked, he was now sitting on the edge of the couch and leaning forward with his head in his hands.
"We are so screwed!" he wailed.
Theresa's eyes welled with tears, and she hugged him. She was still naked too.
"Oh Martin!" she exclaimed, "I'm so sorry! I never meant for any of this to happen!"
"No, it was my fault," he said with a sigh, "I should have known better! I was the one who let my guard down. I shouldn't have said anything that day I saw you in the bathroom. I should have just walked away!"
"I'm so glad you didn't," she whimpered, "I was hoping you'd catch me."
Martin stared at her in surprise.
"What?"
Theresa blushed and buried her face into his chest.
"I wanted you to catch me," she whispered.
She looked into his eyes sadly and put her hand between his thighs. He stared with wonder into her face while she started to massage his cock. Before he knew it, it was hard as a rock again.
"I love feeling it get hard like that," she breathed, "That's what really turned me on that day you caught me. When I saw your hardon inside your pants. It made me so wet!"
He groaned and sat back. She put her mouth on his dick and took it all in. In no time, Martin was thrusting his hips forward to meet her wet mouth. She put a hand on his testicles and sucked his length to the back of her throat.
"I want you to cum inside me again," she said and crawled up into his lap, "Please take me Martin!"
Martin could only gasp in response. He pushed her onto the floor and shoved his hardon into her pussy. She groaned loudly and gripped his hips with her legs.
"That's it Martin," she whispered, "Fuck me!"
Outside the office door, Susan was captivated. The sight of watching two people fucking so intensely was arousing enough. To see that one of them was a man she had known for years, a man she had never imagined having any kind of social life, made her cunt steam!
She had to suppress a moan when she reached under her skirt and into her panties. She pushed a finger into her tunnel and gritted her teeth at the pleasure.
Martin was now sliding his dick in and out of Theresa at a slow pace. Each thrust buried his cock all the way inside her. Each pull back left only the head still between her lips.
Theresa was thrashing from side to side as she held him with her arms and legs. Her moaning was getting louder with every thrust.
When she came, she tensed and held onto him for dear life. Martin just kept plowing into her. With the slow pace he used, he knew he could go on like this for a long time.
He did.
By the time he did cum, Theresa was a sweaty mass of cooing flesh underneath him.
Meanwhile, Susan had cum three times while she watched. Her panties were pooled around her ankles, and she had pulled her bra up so she could tickle her nipples.
When the couple finished making love, she quietly gathered up her underwear and tiptoed out of the office. When she returned to her own office, she fingered herself to two more orgasms before she finally went home.
Monday Week 5
Having spent the entire weekend together, both Theresa and Martin were mostly sated by Monday morning.
Martin sat at his desk with a grin as he downloaded the batch of spreadsheets he needed to work on. He arranged them in order of priority and lined them up on his desktop to be done.
"Can I talk to you?" Susan said diffidently from his office doorway.
Martin looked up and nodded.
"Come on in," he said.
"Where's Theresa?" she asked warily, wondering if she might be out of sight under his desk.
"She's not in yet," Martin said, "I always get in about an hour before she does."
"Good!" she said with a sigh of relief.
She entered the office and sat in the chair facing the desk.
"Martin, this thing you have going on with Theresa could lead to trouble!" she said sternly, "It may seem harmless enough now, you know, when you're both enjoying the, well, you know, the sex!"
Martin nodded sagely and sat back in his chair. He looked her in the eye to show she had his attention.
"I know!" Susan went on, "I've seen it happen in the past! Two people who work together, you know, they fall into something that they think is just fine. Then, after a while, the relationship falters. People become emotional and hurt. Then they start doing things to sabotage each other. It's not good for the people involved and it's definitely not good for the workplace!"
"I understand Susan," Martin said gravely, "I've tried to dissuade her from coming on to me, and I've tried very hard to resist her advances! But it's not easy!"
Susan nodded sympathetically.
"You're saying then that she initiated this whole thing?"
"Oh yes!" Martin replied, "I never even imagined this happening! I certainly didn't engineer it!"
Susan let out a breath and looked at the desk in thought.
