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.
