Alan woke to the sounds of Lexi putting on her underwear and surgical scrubs. He rolled over in his bed and looked at the pile of his clothes, where Lexi had tossed them last night. It was barely sunrise outside, and Lexi's shapely body was lit up by the bedside lamp.

"Jesus, you're beautiful," he said. He sat up in the bed.

She looked up. "You aren't that bad yourself." She came over to the bedside and leaned down and kissed him, and their tongues met. "But I have to get to work. And you do too."

Alan's excitement died down when he thought of work.

"Sometimes I wonder how long we can keep this up."

"Keep what up?"

He gave her a look. He gestured to his apartment. "This. How long before Max finds out?"

Lexi stood up and rolled her eyes. "Don't be a spoilsport. You know how this works. Max is a nice guy, and I like him, and I like you more. A lot more. But for now, this is how it has to be. Until something changes, I get a new job, he gets a new job, or you get a new job."

"But that could be a while."

"It could. But I don't mind." She was fully dressed now, wearing her green scrubs. They didn't do her figure justice, but when she walked, you could tell that underneath she had a model's body. Her hair was pulled back in a tight bun for work. She walked over to the bed and climbed on top of the sheets, on top of Alan. "And I don't mind meeting you this way. Isn't there a little bit of... excitement in it? In keeping this a secret?" She rolled onto her side, and her hand reached down to press against Alan's cock, under the duvet. "In keeping _us_ a secret? From Max?" Her hand began to rub back and forth slowly, and Alan bit his lip and tried not to get distracted. But she kept looking into his eyes as he grew harder.

"Isn't it a little exciting? I know Max probably talks about sex. Brags to you about what he and I do together, when the two of you have lunch. And I know you probably smile at his stories and you tell him you wish you could find a girl like me..." Her hands squeezed his cock tighter, and now Alan's manhood was at full size under the sheets.

Lexi leaned in and whispered into Alan's ear, her lips brushing his earlobe, the sensation driving him wild. "And all the while, you know Max's girl has done crazier things with you, and Max has no idea..." She darted her tongue into Alan's ear, and with that Alan came, his body convulsing under the sheets, staining them with wave after wave of his cum.

"And now, sweetie, I really have to get work. And you do too. Sorry about the sheets." She kissed him on the lips as he panted, catching his breath from his barn-burner of an orgasm.

"Bye! See you in two days." She blew him a kiss as she left the bedroom. He heard her pick up her bag and open and close the front door. He waited until he heard the sound of her car starting and her driving away before he got out of bed.

He put the messy sheets in the laundry. He thought about Lexi as he showered. She was frustrating to him, and yet he knew he was falling in love.

He dressed in his usual shirt and tie and was on the road to work by 8:30. Lexi's nursing shift began at 9:00, at the hospital, but Alan knew that Max thought she'd been at the hospital all night. Lexi couldn't have a better job for hiding an affair, since her hours were so unpredictable and irregular. Max would be furious if he found out how many of Lexi's overnight shifts had actually been spent giving Alan some special attention.

He happened to park right next to Max's Cadillac in the lot beside their building. Their department was on the upper floors and their cubicles were adjacent. Alan hung his jacket on a hanger near his desk, and he looked over the divider. His eyes lingered on the photo of Max and Lexi together, the two of them embracing and smiling for the camera. He thought about the first time Lexi had come into the office to drop something off for Max, the first time the two of them had talked...

"Hey there."

Alan swung around to see Max coming from the break room. He was holding a cup of coffee.

"Hey man, how's it going?," Alan asked.

"Oh, you know, same old same old. The hospital's been working Lexi pretty hard lately, long shifts."

Alan hid his grin behind a grimace. "Ouch. That sucks."

"Yeah. But at least she seems to be enjoying the work."

"Well, good!" Alan had to turn away and pretend to look at his computer so that Max couldn't see him smiling.

The rest of the day went as usual, with Max and Alan working side-by-side at their desks in their departments. The two of them ate lunch together, and Alan made up a story about a date he'd gone on that, in his telling, hadn't amounted to anything. He was actually describing the night he'd had with Lexi, down to the steamy details, but he changed the name of the girl to 'Stacy.'

At the end of the day the two men walked down to their cars together.

"Well, hope the hospital can give Lexi a break soon," Alan said.

"Yeah, me too. Well, have a good one. See you tomorrow."

"Yep!"

The two of them climbed in a drove off from the building in opposite directions.

Alan went home and put on a football game, and ordered takeout. He fell asleep after jerking off, thinking about the next time he and Lexi could get together.

Max drove home too. He pulled up to his house, and parked his car next to Lexi's in the driveway. He unlocked the door and came in, and saw Lexi's scrubs on the couch where they'd been left them that morning. He went to bed early. He'd had a long day.

A few days passed before Lexi had a chance for another rendezvous with Alan. They planned to make it a Tuesday night after work. Lexi told Alan that Max thought she had to work a double shift. All day at the office Alan had to try not to think about seeing her that night, so he wouldn't get too excited and get a hard-on right there at his desk.

He and Max parted ways the same way they always did, and Alan drove home, and Max drove to his house too. Lexi's car was there in the driveway.

He came into the house and went to the bedroom, then went to the room behind the bedroom.

When he'd first begun, donning the disguise had taken him almost two hours. Now he had it down to only 30 minutes. The corset around his waist came first. Then the artificial vagina, a false cavity that allowed him to feel pleasure during sex as his own cock was rubbed against by whatever was inserted. Then the padding, adhering it to his ass and his chest. Then the bodysuit itself, a thin but tough layer of latex that looked exactly like skin. He sealed the edges and then braced for the final part, the mask -- one single piece, the neck and head, with the hair attached. He sealed the seam between the bodysuit and the mask, and the disguise was complete.

He put on the green surgical scrubs and grabbed Lexi's handbag. He thought about making the photo of him and 'Lexi' that he knew Alan looked at on his desk. It was Max and an ex-girlfriend; he'd simply PhotoShopped a picture of himself wearing the disguise onto the woman's body.

He left his house and got in Lexi's car. In twenty minutes, his excitement growing, he was standing in front of Alan's house. Max rang the doorbell and got into character. The door opened. Lexi rushed in and embraced him, her tongue probing at his mouth. She could already feel Alan's hard-on growing in his pants.

She smiled. Max had a secret, and Alan had no idea.
