The next morning Martin showed up late again.
He went to the toilet and stared at his reflection in the mirror. He sighed unhappily and went to the urinal. He unzipped and dangled his penis over it. It took a long time for him to be able to pee. His hardon was interfering.
When he finally finished, he returned to his desk just in time to see Theresa arrive.
"Good morning," she said and then took a seat.
"Morning," he muttered distractedly.
Martin went to his desk in a state of anxiety.
He looked down into his lap and saw he was still sporting a hearty boner. He glanced up at Theresa who was reading emails on her computer monitor.
She looked really good today too! She was wearing a sweater-dress, similar to the one she'd worn yesterday, but it was blue, not beige. Martin wondered if her underwear matched the color of the dress the way it did yesterday.
As his hardon pressed against his slacks, he decided to nip this in the bud before it got out of hand.
"Theresa?" he called.
She grinned and stepped into the doorway of his office. Martin could see the outlines of her bra and panties beneath the dress and he sighed with relief.
'At least she's wearing her underwear today!' he thought to himself.
"I want you to put some filing boxes together," he said, "You'll find them in the storeroom outside Susan's office. Grab four of them and then start on the A's in the cabinet right here. You're going to place them into the boxes. After you've finished with the A's, let me look it over. Then you'll start on the B's."
"Sure thing boss!" she said with a happy smile.
He went to work on the new figures he received in his email. By the time she returned, he was well into having a productive morning.
Theresa leaned the ready-to-assemble boxes against the file cabinet. Over the next ten minutes, she tried several times to fold the first one properly. Martin looked up at one point to see she had messed it up horribly.
He snickered a bit but then stood and knelt on the carpeted floor with her. He went through the process with her and eventually she had folded it properly.
"Wow!" she said in frustration, "That was really hard!"
"It can be confusing," Martin agreed.
"I'm set now," she said.
Then he returned to his desk and went back to work.
He glanced up to see her bent over the file box as she tried to arrange the file folders in it.
She was leaning forward and concentrating on placing the folders into the box carefully. Her rump was raised slightly with her knees tucked up underneath her and her feet splayed out behind.
That was when he noticed that the panty-line under her dress was gone. The knit fabric was pulled taut against her bum showing no folds or lines beneath it at all.
He stared and swallowed nervously.
She really did have a nice ass! It was perfectly round and stuck out prominently.
He went back to looking at his work, but it was no good. He couldn't keep his eyes from drifting toward the girl bent over in front of him.
She turned her head and grinned when she finished arranging the folders in the file box.
"You said you wanted to look this over before I went on to the B's," she said.
"Um, yeah," he said and coughed uncomfortably, "Let me look!"
He went and stood over the girl and the box. As he checked to see the box was appropriately filled, he glanced toward her chest. How could he not?
Her breasts were held firmly by the knit dress but there was no sign of a bra underneath it.
Martin licked his lips and nodded.
"That's good," he said, "I'll, um, be right back."
He rushed toward the bathroom and closed the door behind him hurriedly. He stood with his back to the door breathing heavily.
"This girl is going to drive me crazy!" he muttered to himself.
He washed his face with cold water and concentrated on making his boner disappear. After several minutes, he thought he had himself under control at last.
He returned to his desk and saw his office was empty.
He looked toward the outer office but there was no sign of Theresa. He shrugged and walked to his desk.
That was when he saw her blue dress, a matching pair of panties and a bra stacked neatly on the desk by his phone. He stopped dead and stared at them in shock.
In something of a daze, he backed toward his chair and sat heavily. He stared at the clothing and shook his head in wonder and frustration.
Then he looked under the desk and his breath caught in his throat.
There was Theresa, naked as the day she was born, but wearing her large glasses. Her eyes reminded him of an owl's as she stared up at him from between his thighs.
She reached for his slacks and opened his fly. Then she fished his hard penis from his underwear.
She scuttled closer to him and placed her hands on his knees. He could see her ripe boobs with their bright red nipples hanging so delicately from her small frame. If he looked carefully, and he did, he could also see her sparse pubic hair tucked between her thighs.
She leaned forward and took the head of his cock into her mouth. All the while, staring up at him with her wide eyes. He could only watch as this mousey young girl slid her mouth slowly up and down his shaft.
He whimpered softly and she gave him a half-smile around his penis. It was like she was looking for his approval.
She definitely had it! He hadn't had a blowjob in quite some time. He'd never gotten a blowjob at work!
She lovingly mouthed his cock, running her tongue up and down its length and swirling around the head. What she didn't know in technique, she more than made up for in enthusiasm. She put her two hands around the base of his dick and took just the head into her mouth. She slowly moved her hands up and down the shaft while suckling on the head.
Martin groaned softly and she closed her eyes for a moment in enjoyment. Then she put one of her hands between her thighs and started to finger herself. Soon she was rocking back and forth on her hand while at the same time taking his penis all the way to the back of her throat. Her to-and-fro movements had Martin biting his lip.
He was going to shoot soon.
She continued to suck him and finger herself moving faster and faster as she went. Martin placed a hand on her head and leaned back in his chair. When he shot his load she clamped her lips around him and didn't let a single drop fall to the floor.
When Martin opened his eyes again, he looked down to see Theresa with a happy smile wiping a few stray drips of semen off her lips.
She reached up from under the desk and grabbed her clothes. She giggled slightly as she struggled to wrap her blue bra around her back.
"Hey Martin!" a loud voice called.
Martin practically jumped out of his skin!
He looked up to see Susan Wield striding into his office door.
"I came to find Theresa," she said, "Is she in the washroom or something?"
