Put through their paces.

“You could join me in the gym,” Melissa suggested.

Nathan wasn't sure if the hot older Asian woman had got what he'd been hinting at, but by this point he was beyond caring. Nathan nodded his agreement and followed the lawyer in the deep red spandex towards the elevator, quickly adjusting himself when Melissa pressed the call button and wasn't looking towards him.

The hotel's fitness centre was in the subbasement, so they rode the lift together to the very bottom floor. Nathan tried to start a little small talk to fill the time.

"So, what do you do?" the enamoured teen asked.

"I'm a senior litigator at my firm," Mel told him.

Nathan looked confused.

"I'm a lawyer," she told him more simply.

"Oh yeah, that makes more sense. I didn't think you farmed crocodiles."

Melissa was well and truly confused for a few seconds there until Nathan explained it to her.

"Litigator... Alligator," he said.

Melissa snorted as she burst out laughing. Oh, bless this child, she thought. He was either very dumb or actually rather funny. She wasn't sure but found it intriguing.

Down in the gym, Nathan and Melissa were the only two people in the place when they came inside. It was the standard sort of set-up you would find in almost any hotel. A small number of machines, a pair of treadmills and only the barest of free weights. It was pitiful compared to the state-of-the-art weights room Nathan was used to.

It was more than enough for Melissa, who was more of a cardio bunny than Nathan would ever be. "Want to warm up and stretch before we work out?" Mel asked.

Actually, doing real exercise wasn't the sort of workout Nathan had in mind when he'd agreed to come with Melissa. His thinking had been taken over entirely by his lower brain thanks to step-sister Tiffany.

Melissa dropped her gym bag beside one of the benches and started rolling her shoulders.

“Come on,” she said. “If you're actually going to work out with me, you should stretch first.”

Nathan followed her onto the exercise mat. “I stretch.”

Melissa gave him an amused look. “Do you?”

“Absolutely.”

“When?”

Nathan paused. “Occasionally.”

She laughed. “That's what I thought.”

Melissa sat down and extended one leg in front of her. “Reach for your toes.”

Nathan copied her, though his flexibility was considerably worse.

“That's embarrassing,” Melissa said.

“What?”

“You're barely moving.”

“I've got long legs.”

“That isn't an excuse.”

“It’s easier for you; you’ve got…” Nathan didn’t get the chance to finish the sentence before Melissa’s eyes flashed angrily.

“You are not about to say I’ve got shorter legs.”

Nathan covered quickly. “No! I was going to say shapely. Very shapely.”

Melissa pursed her lips, somewhat mollified by his quick recovery, but he thought he caught the hint of a smirk there too.

Allowing the slip to pass, Melissa shifted closer and gently pressed a hand against his upper back. “Come on. Bend forward.”

Nathan immediately felt the warmth of her hand through his shirt. “Like that?”

“A little farther.”

He stretched forward.

“Better,” Melissa said, keeping her hand between his shoulder blades for another second before letting it fall away. “See? You're not completely hopeless.”

Nathan looked up at her. “High praise.”

“I don't give compliments easily.”

“I'll remember that.”

Melissa smiled and moved around him to demonstrate another stretch. “Your turn. Stand up.”

Nathan got to his feet.

Melissa stepped behind him and raised his arms slightly, her fingers briefly brushing his wrists before settling against his forearms.

“Shoulders back.”

He obeyed.

“Relax.”

“I am relaxed.”

“You're about as relaxed as a soldier standing inspection.”

Nathan laughed. “Maybe I'm nervous.”

Melissa raised an eyebrow. “Nervous?”

“First time working out with a lawyer.”

“Ah. Terrifying, I know.”

“Senior litigator, actually.”

She laughed. “You've been listening.”

“I remember important things.”

Her hands remained lightly on his arms for a moment longer than necessary. When she finally stepped around him, they found themselves standing surprisingly close.

“Careful, Nathan,” she said. “You keep saying things like that, and I might start thinking you're flirting with me.”

Nathan smiled. “Maybe I am.”

Melissa held his gaze for a beat, then gave him a light push on the shoulder. “Then you'd better impress me.”

“With running?”

“With something.”

Nathan grinned and climbed onto the treadmill beside hers. “Race you?”

“You're on.”

The two machines started almost simultaneously. Nathan immediately pushed his speed higher.

“Showing off already?”

“You told me to impress you.”

“I said something. I didn't say you had to kill yourself.”

Nathan laughed and increased the speed another notch.

Melissa shook her head. “You're trouble.”

“That's what I've been told.”

“By whom?”

Nathan glanced sideways at her. “Mostly women who should know better.”

Melissa laughed, reaching across to tap him lightly on the arm. “Cocky.”

“You like it.”

“I didn't say that.”

“You didn't say you didn't.”

She shook her head, but the smile stayed on her face.

After several minutes, Melissa slowed her treadmill. “Okay, show-off. Enough.”

Nathan slowed beside her.

Mel stepped off, and when Nathan followed, she reached out and straightened the front of his shirt where it had twisted slightly during the run.

“There,” she said. “Much better.”

Nathan looked down at her hand and then back into her eyes.

“You do that with all the men you work out with?”

“Only the ones who need supervision.”

“Lucky me.”

“Don't get carried away.”

She gave his shoulder another playful squeeze before walking back toward the weights. He watched as she picked up a pair of 5-kilo dumbbells and lifted them so they were resting on her shoulders. He continued to stare as she started to dip down into a squat and then back up again. As she moved, Melissa’s lovely, round arse stuck out each time she poked her bum toward Nathan. He couldn’t make out even a hint of a panty line, so he guessed in delight that the Asian woman must be wearing a thong underneath.

After a few repetitions, she glanced over her shoulder.

“You're awfully quiet all of a sudden.”

Nathan smiled. “I'm concentrating.”

“On your workout?”

“Mostly.”

Melissa's eyebrow lifted. “Mostly?”

Nathan shrugged, suddenly aware that there wasn't much point pretending he hadn't been watching her. “You're distracting.”

Instead of looking offended, Melissa smiled. “Am I?”

“You know you are.”

She held his gaze for a moment before turning back toward the weights.

“Then perhaps you should do something about it.”

Nathan wasn't sure whether she was joking. The small smile she gave him over her shoulder suggested she knew exactly what she was doing. She lowered herself into another squat, then straightened again.

“Not going to give me a spot?”

Nathan laughed softly. “Do you actually need one?”

“No.”

The answer came so quickly that they both smiled.

“But,” Melissa added, “you seem like you could use something to do.”

Nathan stepped closer. Melissa didn't move away. He placed his hands firmly on her hips, and she didn’t object. He could feel the considerable heat coming from her body from the warm-up. As she lowered herself again now, Nathan held tight to her as he pressed up against her rear. After three repetitions, Nathan felt Melissa begin to grind back against his groin. Blood quickly flowed, and his cock hardened, pressing up and between her cheeks.

He was puffing, and not from the workout, by the time Melissa switched things up.

“Your turn,” Melissa declared as she dropped the weights onto the floor with a dull clang and pushed Nathan backward toward an incline bench. He didn’t even get time to lift a weight before Melissa climbed onto his lap, straddling him. She settled her pussy in tight Lycra directly on top of his hard-on. She leaned down and kissed Nathan hungrily.
