Ruth entered the office even later today; still no random meeting with Reg, though, to her bitter disappointment. 'Wednesday, god, I wish we had managed a fuck yesterday,' Ruth thought all the way from the car and up the elevator, noticing how wet she was.

Ruth settled at her desk. Although she was logged in, her attention was on the lift doors. She had found her short grey skirt ride up as she adjusted some cleavage in her black blouse.

Her eyes flirting between her screen and the lift, her heart pounding, waiting for him to arrive.

The elevator doors slid open. Ruth's heart leapt into her throat, her breath catching in her chest; this time it was Reg.

And she couldn't help but leer at the sight of him strutting out of the lift, his shirt untucked, his hair ruffled just enough to look perfectly imperfect. She watched his confident stride; she felt her pussy clench in response.

Ruth quickly unbuttoned her blouse further, just a few more buttons, enough to give him a tantalising glimpse of her black and red lace bra, the one she had bought just for him.

She licked her lips, her eyes locked onto his as he walked past her desk. She could see him glance down at her chest, his eyes lingering for a moment as he passed, his appraising eyes taking in the offering she made to him; a small smirk played on his lips.

Ruth could feel her fingers tremble with excitement and sexual tension as she buttoned herself back up, ensuring that it was only Reg who got such a good view of her assets. She waited a moment, her heart pounding in her chest, waiting for his call.

Ruth resisted sliding her fingers up to between her legs; she also fought against crouching up in her seat to look around at him, not wanting to draw any attention to herself or what they had been doing all week. She had to remain composed and professional, she reminded herself.

As Ruth tried to focus on her work, she fought the urge to look up more and more; her body was on fire, every nerve ending tingling with anticipation as she wanted to be appreciated by him, touched by him.

When her work line rang, Ruth dared let it ring again before picking it up, trying to sound casual rather than racing for the phone.

"Good morning, Ruth," she said as casually as she could.

"Good morning, is this the hot blonde a few desks down, the one who sent me all those naughty pictures last night and this morning?" Reg teased.

Ruth replied with a playful tone, "What was I supposed to do all night long? Nothing to do, no one to fuck. You expect me to just wait until today to see you to get my kicks?"

"Well, you get off wearing those cum-filled panties; the video you sent me was nice and got me good and hard for my wife," Reg said.

Ruth bit her lip, her nipples hardening under her blouse. "Maybe I'll make you a special video, something just for you, to watch while you're stuck at home with your vanilla wife. And you did look very dashing today," she told him.

"And so did you; that bra is better on than in the pictures from this morning," Reg told her, his voice seductive.

"So, what are you doing for lunch today?" Ruth asked eagerly.

Reg's voice was laced with lust, "Can't do lunch, conference call, but we have tonight. Did the old loser hubby buy you? Are you working late?"

Ruth's breath hitched in her throat. She quickly looked around the office, but no one was paying them any attention.

"Oh, he did. Told him about a client dinner tonight, but really I wanted a little something before then," Ruth complained, her voice full with need. "What do you say to a quickie before the call?"

Reg groaned into the phone. "Fuck, I want that. But sorry, we just need to wait, and more bad news – I forgot I have a parents night tonight, so it will need to be a quickie after work."

Ruth bit her lip, her body aching for him. "Ok, if that's all I get I'll take it. But you better make it good," Ruth said, her voice low and husky.

Reg sighed, "I'll make it good, very good. Now how did you get on with my, what did you call it, ah, baby swimmers wriggling around in your panties all night, right next to hubby?" Reg asked with a mischievous laugh.

"It was filthy, fucking filthy and amazing; I loved feeling your cum soak through the fabric while I slept," Ruth replied, her voice a husky purr. She turned to face Reg, her eyes dark with desire. "I woke up so horny, but I couldn't touch myself until he left for work. Imagining your cock inside me all night, I did kind of forget through the night and rubbed myself over his thigh; I was imagining it was you beside me."

Reg's eyes darkened with lust, his cock twitching in his pants at the thought. "Fuck, that's so fucking hot, as long as that's all he got," he growled.

"It was," Ruth said very quickly and more defensively than planned.

Reg's lips curled into a devilish smirk. "Good, because I wouldn't want him to know what it feels like to fuck the living shit out of you ever again."

***

Ruth and Reg tried their best to get through the day, sending each other flirty texts and stealing glances across the office when they could, her thoughts drifting between what she was going to do to him and what he was going to do to her later.

The day seemed to drag on, but eventually it was time to leave. Ruth watched Reg pack up his things, her heart pounding in her chest with anticipation. They walked silently to the elevator, Ruth's hand brushing against his as they entered. The doors closed behind them, and they were alone.

"Finally," Ruth breathed, her voice a low purr as she turned to face Reg. Her hands went to behind his head, her lips to his.

Reg's hands went to her hips, pulling her closer to him as he let out a low growl into her mouth.

Ruth's fingers tangled in his hair, pulling him closer as she deepened the kiss. She could feel his cock pressing against her, hard and ready, as she ground against him purposely in the confines of the lift.

Ruth broke the kiss, breathing heavily as the lift stopped.

They were finally alone in the parking lot. Ruth pulled away from Reg, her hand letting go of her grasp on his. She led him towards her car, pressing the key fob, the car lights flashing twice in response. Ruth pulled open the back door, climbing in first before Reg followed, closing the door behind him.

She wasted no time, turning to face Reg, "I need you inside me," she panted.

Reg smirked, his hands going to his belt.

As he undid the belt Ruth was reaching over, she asked, "What's got a thousand teeth and holds back a monster?"

Reg shrugged, "No idea."

"Your zip," she teased as she pulled the zipper down and pulled his cock free.

"I wish we had longer," Reg told her, laughing.

Ruth bent down; right before she swallowed his cock, she told him, "Me too."

"God, yes, that's fantastic"  Reg groaned as he felt her warm mouth envelop him. Ruth knew how much he enjoyed her giving him head, and she was more than happy to oblige. Her head began to bob up and down on his cock, her tongue swirling around the head each time she took him in her mouth.

Reg's hand went to the back of her head, his fingers tangling in her hair as he guided her head up and down, fucking his cock with her mouth. "Hubby is still paying this car off for you," he groaned.

Ruth moaned around him, her hands going to his balls, cupping them and massaging them gently as she took her mouth off him. "Yeah, he pays for it," before she went back down on him.

"You blow me in it; I love that," Reg said.

Ruth swirled her tongue around his shaft and released him again.

"I hope that not all we are doing in it?" she asked.

"I wish we did have longer," Reg said, his voice a low growl. Ruth pushed him back onto the back seat, her eyes locked onto his as she quickly kicked off her high heels before unbuttoning her blouse and unclasping her bra.

With a swift movement, she reached for her panties and slid them down her legs before tossing them onto the seat beside Reg. She turned to face him as she climbed onto his lap, straddling him in the back seat. Ruth could see the hunger in Reg's eyes as she ground against him, his cock still slick from her mouth; she was face to face with him.

"I want you inside me," she whispered, her voice a sultry purr as she reached between them, her hand wrapping around his cock and guiding it towards her slick entrance. Reg groaned as she kissed him hard, his hands gripping her ass tightly below her hitched skirt as she slowly lowered herself onto him, taking him inch by inch.

Ruth broke the kiss as he slid deeper inside her, moaning loudly inside the car.

The sound of their combined moans filled the car as Ruth began to move, her hips rotating in slow, deliberate circles as she took him deeper and deeper until he was immersed fully inside her. She leaned forward, her lips finding his ear as she whispered, "I want to feel you come inside me again. I want to feel your hot cum filling me up."

Ruth's voice was a low, breathy moan as she began to move on top of him, her hips sliding up and down, his cock in and out of her, her muscles clenching around him.

Reg's hands gripped her ass, his fingers digging into her soft flesh as he helped to guide her movements, urging her to ride him faster, harder. "Fuck, Ruth, you feel so fucking good," he groaned.

Ruth whispered in Reg's ear, her hips moving faster, riding him harder. "Because I want you to wear me. I want my cum all over your cock when you go to parents night, acting the faithful husband. I want you to think of me, of this, every time you move, every time you look at your stupid wife."

Reg groaned, his hands gripping her ass tighter, urging her to move even faster. "Fuck, Ruth, you're going to make me come," he grunted, his body tensing as he felt his orgasm building.

Ruth felt her own climax approaching, her breath coming in short gasps. "That's it, baby. Give it to me. You are going to make me cum all over your big dick," Ruth whispered, her words coming out in short, breathy gasps as she rode him faster, harder.

"Fuck yes, baby," Reg growled, his hips meeting hers thrust for thrust, their bodies slamming together with each movement. "I want to feel you come all over my cock. I want to feel your pussy clench around me as you cum."

Ruth's breath hitched, her body trembling on the brink of orgasm. She could feel the pressure building inside her, her clit throbbing with each thrust. She leaned forward, her hands gripping Reg's shoulders, her nails digging into his skin.

Reg's orgasm took her by surprise; he was quicker than she realised. As his cum flooded inside her, she began to scream in pure ecstasy, her body shivering and her pussy milking his cock for every last drop.

"Fuck, fuck, fuck, YES!" Ruth screamed as the waves of pleasure crashed over her, her body convulsing as her own orgasm ripped through her. She felt like she was floating, her vision hazy as she rode the pleasure, her body shaking.

Ruth collapsed onto Reg, her body slick with sweat, her breath coming in short gasps. She could feel Reg's cock twitching inside her, his hands gripping her ass tightly as he continued to grind against her, riding out his own orgasm.
