Andy gathered his Korean mistress in his arms off the couch - they were both in their underwear now, bathed in guilty midday light - and carried her through his tiny apartment, past photos of his wife and young son, now traveling overseas. He walked her into the single bedroom and tossed her on the bed. She crashed in a tangle of limbs and giggles and he leaped on the bed after her. Her legs scissored open under him, and he leaned down to her, and they kissed. 

"You're driving me crazy at school," he mumbled, between kisses. "I can't keep my eyes off you." 
 
"You naughty man," Sung-gyung said to her classmate, between nibbles at his neck. She caressed his broad, bare chest. Their kisses got deeper, as did their breathing. 

"Are you ready to do this?" He asked. 

"I don't know," she said, playfully. "Are you?" 

They kissed. "I don't know if ... it ... works with another woman," Andy said. "My God, it's been so long. I've been married so damn long." 

She laughed and caressed his shoulders. "I don't know if this will work," Sung-gyung said. "I don't know if you'll... fit. I've never been with anyone other than my husband. And you're bigger than Dan." 

Andy arched his brow. "There's only one way to find out, right?" 

"No turning back now," she said.

As with most things sinful it had started with the appearance of innocence. They were in a graduate level class together, and when the day came to partner up for discussions they happened to be sitting next to each other. It wasn't an accident at all, of course. They'd both noticed each other from day one and each made a mental note to themselves to sit next to the other on the day the syllabus indicated group work. So when it came time to pair up they glanced around, made eye contact, introduced themselves, and then settled in next to each other.

Their initial observations of each other weren't misleading. Not only did they like each other's good looks -- she liked his rather burly appearance, rugged good looks, and he liked her slim, perky and Asian look -- they found they had a similar sense of humor. He could make her laugh and he could sense that her laugh was genuine. They began to sit next to each other regularly. They tried not to make it a big show -- they were both married, he with a kid -- but on about two-thirds of the days they were within whispering distance of each other. 

One day after class he asked if she wanted to grab lunch with him. Thus another hurdle was cleared, and they had a two-hour lunch. They each went home and told their spouses about it out of guilt, but neither mentioned how long the lunch had lasted. The truth was he'd said things that made her giggle for days afterward, and her sunniness shone in his mind for days, too. It wasn't long before they had another lunch. And then another. 

The real tipping point came after their lunches became regular -- every Tuesday and Thursday, and, again, not mentioned specifically to spouses, though they would never admit to each other at this point that they weren't completely open to their spouses about each other -- and Andy mentioned one day that he works regularly late in the graduate lab, a tiny room filled with computers and ratty couches. 

"Is it quiet then?" Sung-gyung asked, not really caring if it was or not. 

"Yeah," Andy said, trying to find the answer she wanted. 

"Maybe I'll take a look," she said. "Dan can be so annoying at home. He likes to relax at night and I have to work." 

"Come to the lab!" Andy said, a little too enthusiastically. "My wife is the same. It's my refuge." 

'We'll see," she said. And of course she did. The lunches, the evenings in the lab -- often they had the place to themselves -- and the sitting next to each other in class, it all became regular. People began to talk. 

"So," said Hanna, Sung-gyung's friend, as they had lunch one day, "have you seen Andy? I was trying to find him for something." 

"What for?" Sung-gyung said. 

"Just some thing," Hanna said, watching for a reaction. She saw mild irritation cross Sung-gyung's eyes. 

"It IS true," Hanna said, pointing a finger at her. "There's something going on, isn't there. Between you and Andy." 

"I am offended," Sung-gyung said. "You were my maid of honor! I'm married! How could you think that?" 

"Hey, don't get pissy with me," Hanna said. "Everyone is saying it. You two are acting like a couple." 

"We are not!" 

"Oh yeah? Guess what someone said the other day. They were looking for Andy. Someone else said, 'I just saw Sung-gyung up in the lab. He can't be far away.' And sure enough, I went up there and there he was. You guys were sitting next to each other." 

"Who said that?" 

"It doesn't matter," Hanna said. "Look, Andy is a dream boat, but you're walking down a dangerous path, girl. This is marriage you're talking about! Both of you! What are you thinking?" 

"I'm not thinking anything," Sung-gyung said, gathering her things. She stood up. "I thought you knew me better." She stormed out. 

"I thought I knew you better too," Hanna said into her drink. 

Sung-gyung didn't show up to the lab that night. The next day, in class, Andy gave her a look but she avoided eye contact. It was Tuesday, lunch day, but she didn't show up. Finally he caught up with her in the parking lot. 

'What's going on?" He said. "You've been distant today." 

"So?" She said. "Why all the worry? Friends don't fuss over each other like that. You're invading my space." 

"Oh," he said, and she slammed the door shut, and left. 

That night at the lab, Andy was wrapping up his work when he heard the door open around midnight. Sung-gyung walked in alone. He looked back to his computer. She sat down next to him and faced him. 

"I'm sorry about earlier," she said, putting a hand on his shoulder. "I was having a bad day." 

"That's okay," he said. "Maybe you're right. I was too concerned. Maybe we should..." 

"Back off? That's what Hanna said. That's why I was so upset," Sung-gyung said. "We look like a couple. I don't know what's going on." 

The lab was empty. Andy swiveled his chair and looked at her. "I don't know either," he said, finally. Then he took her hands in his. She allowed it. He kneaded her knuckles with his fingers and thumb. His index finger rubbed her palm. 

'Ever since my son was born my wife has been so distant," he said. "I guess I was glad to discover some of the old fire. But it was with you, and it confused me." 

She squeezed his hands. "I found it, too," she said. "And I was confused. Guilty. I've only been married two years. But Dan has had bad luck with his job, and he's gotten a little down, and we've been fighting. Haven't done anything... physical... in months. Not that I'm a nympho or something but you need to be touched. It leaves a gap if you don't, and you came along..." 

A tear fell down her cheek and he wiped it away. She looked up at him, her eyes moist, and he leaned to her, and they kissed. At first it was just a test peck, to see if she was willing, and then it went longer, and her mouth parted slightly, and their chairs creaked as they embraced. 

"Oh Andy," she whispered, running her hand over his arms and shoulders and chest. His hand swept down her curved side as they kissed, up again, brushed her breast. She let out a little gasp. 

"Sorry," he said, pulling his hand away. She grabbed it and pulled it back, so it covered her breast entirely. He felt it through her top and bra. It filled his hand nicely. 

"It's about time," she whispered, between their kiss, and he massaged her breast firmly. 

They heard footsteps and lurched apart. She ran a hand through her hand to straighten it and had just started the computer when the lab door opened. Sung-gyung's face fell. It was Peter Haines, who often spent the entire night in the lab. The secretary told stories of coming in at 8 a.m. and finding him asleep on the couch. 

"Have you seen my jump drive?" Peter said, in his scrawling voice. 

"Sorry," Andy said, his eyes darting to a machine across the room with a little portable drive hanging off the back. "Haven't seen it." 

'Dammit," Peter said. "Now I have to go all the way back home. And I had a big project to work on." 

As soon as the door shut behind him Andy was up. He locked the latch and killed the lights. The only light was the exit sign and the computer screens. He and Sung-gyung met at the couch. They sat in it and resumed enthusiastically, the dam finally opened. His hand went up her shirt, wriggled under her bra cup and grasped her breast in full. She sighed and threw her head back. He kissed her neck, then her ears. Her fingers fumbled with his shirt buttons. When they were undone she ran a hand along his smooth chest. 

"So smooth," she whispered excitedly, "so big." 

His hand swept down and grabbed her ass. It was round and firm; his eyes had spent many hours on it. She laughed and, showing remarkable flexibility, tossed one leg across his thighs, then another between he and the couch. She pulled his neck and they lowered to the horizontal, with her knees on either side of him. Both her hands ran along his chest now; he still had one on her breast and one on her ass, balancing him while feeling her. They kissed fiercely. 

Her hands dropped to his waist line experimentally, to see how he'd react, and, with no resistance, lightly tugged his belt. Still no resistance, she yanked his belt. It came undone. 

"RIght here? Now?" He said. She nodded and unbuttoned his fly. Then she unzipped his pants. She pushed at the cloth and it slid down his ass, and his swollen penis flopped out, twitching. She smiled and closed her eyes, and grabbed it in both hands. 

"Oh Andy," she said. "You're getting all ready for me? You're so big..." 

"Take yours off," he said, feeling for her waist strap with his fingers. 

The lab door rattled. They froze. They heard the jingle of keys. 

"Shit!" Andy hissed and sprung off Sung-gyung, and fumbled wildly with his pants. Stifling her laughter, Sung-gyung grabbed her things and, closely followed by him, the sound of keys ringing in their ears, she dashed into the back room, where they hid in one of the cubicles. 

THe lab door opened and the light flipped on. They heard humming. It was Peter. A chair creaked. A computer turned on. 

"This could be a while," Andy dead-panned, and Sung-gyung laughed into her hand. 

They waited in silence. Sung-gyung's cell phone went off on vibration. It was Dan. She shrugged at Andy. He shook his head. 

"I have to go," she mouthed at him. He nodded. 

Finally Peter got up to go to the bathroom. They slipped out, went downstairs, and exited to the parking lot. Finally they began to laugh. THey stopped by her car. 

"I have to go," she said. "I'm sorry." 

"Can't we do it in the car?" 

"No!" She said, slapping him. His face fell. She saw it and kissed him full on the mouth. 

"Tomorrow," she said. "We skip that boring class."

"They'll see us both gone and talk." 

"To hell with them." 

He smiled. "Agreed. I'll meet you at our lunch place?" 

She nodded. When he turned to go she gave him a feisty slap on the ass. Neither of them slept much, but when they met the next day, they were ready. 

*** *** ***

They were on the bed he shared with his wife. They kissed. Her hand flitted like a bird over his midsection, brushing him with the back of her hand at first. She felt a heavy thing bundled there beneath his underwear. He moaned lightly. 

"Well, something is happening down there," he said, licking the lobe of her ear. "There's only one way to find out if we... work." 

"Oh yeah?" She said, arching her back and undoing her bra. "How's that?" 

He peeled off her bra and thrust his mouth hungrily into her breasts. Her nipples swelled into his tongue. Sung-gyung cried out. His two big hands swept down her back, under her panties strap and pushed them down to her knees. She lifted a knee, wedging it in his belly, pulled the panties off one ankle, then the other, tossed it to the floor. Hands free, she pushed them under his briefs strap and grabbed his penis. Her mouth formed a little 'o' as she felt his hot, twitching stiffness in her hands. 

With one hand he reached down and pushed off his own briefs, kicking them onto the floor in a flurry. Her knees spread beneath him and she stroked his penis firmly. 

"So far so good," she said, and he laughed. 

"Are you a baseball fan, my dear?' He asked. 

"Why?' 

"Because I think it looks like I'm going to find out how you do with a  man in scoring position," he said. She laughed and squeezed his penis. 

"Come here," she mumbled, kissing his mouth. "Let's see if we work." 

He lowered his naked body onto hers. She felt a long, hot stiffness sticking awkwardly between them, poking her, and then he began to shift his hips and drive his knees around her legs. She ran her hands up and down his side, feeling his weight stretch her legs outward. 

"This might just work," she said, enjoying his masculine weight. "It might just work." 

"Uh huh," he mumbled, breathlessly. His hips began to gain some rhythm, and she felt herself dampening as his rod prodded her skin. She felt his testicles swaying and bumping her inner thights, and felt his stiff pubic hair brushing hers. She brought her legs up to press them, her calf to his ass. 

"I might just work," she repeated. "We're gonna find out..." 

He nibbled her ear and pressed his chest against her. She felt his heart whamming against her breasts as he pressed his hips into hers and swayed them back and forth. Her hands found his ass and pulled, and he lifted it, and lowered it, and she felt his penis at a new angle, one that put the point against her, and he moved forward at this new angle, and pulled back. 

"That's the way we have to go if this is gonna work," he said. 

"Do it again," she said, through half-slitted eyes. "Oh, baby, I want this to work." 

She felt his penis surge again at the new angle, and she knew if it was going to work, this was it. She drove her hips down as she felt him moving up, his bellybutton sliding along her navel, and she felt this hot, blunt pressure meet resistance - she felt her skin all below her belly seem to stretch - and then she felt something swelling inside her, moving up toward her belly button. Andy was moaning. 

"Oh, Andy!" She moaned. "I feel you! I feel you!"  

"Am I hurting you?" 

"Ohhh but it hurts good," she breathed. "You're big and hard and I love it." 

He began shifting his hips again, and she opened her eyes to see his slick penis disappearing below her furry mound. He rocked against her, and she bit her lip as she attempted to keep his heft inside her as he found a groove. It wasn't easy at first. It kept popping out, but each time his reentry was easier, and then they found their rhythm, a bed-shaking thing, and when he threatened to spill out again he grasped her ass and pulled her into him hungrily. She let out a full-throated moan. 

"Oh baby," she moaned. "It works, it WORKS..." 

"It's not easy... but it's worth it..." 

"It's such a fucking turn-on though..." 

"I know..." 

"To have to work so hard to keep it in..." 

"Oh," he said, nodding vigorously, his hips swaying into hers, grinding her ass into the sheets, "I LOVE it... you're so TIGHT..." 

Her cell phone began to ring. 

"The hubby?" He said, pressing his cock deep into her pussy. 

"Probably," she said. "I'm kinda busy right now..." 

It rang and rang. 

"He's persistent," he said, thrusting.

"Let it ring," she moaned. "Let it fucking ring... I've got a man in scoring position." 

"Oh, yeah, you do," he said. "This is incredible." 

"And right where you do your wife," she mumbled, feeling him strain against her. "You naughty man." 

"This is so much better..." 

"We should have done this earlier..." 

Words escaped them, replaced by the protesting springs, moans, and, finally, cries. She felt his prong enter her deeply, and then the hotness was wet, too, and she dug her fingers into his sweaty scalp, crying out his name as he exploded inside her. His penis pulsed against her clitoris and she finally let herself go, the orgasm making her vagina patter against his penis like a drum. 

"I think that worked," he said, as they slowed down. 

"I think the neighbors would agree," she said. 

"Hell with 'em," he said, and rested his head on her breasts.
