He should try it out first

"I just don't know if spanking is even something we'd enjoy," said Chris, attempting again to decline politely. The music was still pounding in his head, making it hard for him to put a firm foot down.

Catherina smiled. "Most new sexual experiences are instigated by one person. Not both." She grabbed his hand holding the paddle and squeezed, prompting him to tighten his own grip.

Chris had to admit that it made sense. Usually ideas don't spontaneously incept in multiple people. It only made sense that boundaries in a relationship would be pushed by a single person at any time. The thumping beat from the store's sound system continued to pervade his senses.

"And most sexual partners," continued the gorgeous temptress, "Want to enjoy what their lover enjoys." She let go of Chris' hand and turned away from him. With a seductive sway, she began to walk away and Chris' eyes were once again drawn to her ass hidden by the red, swinging mini skirt.

Through his lustful haze and the pervasive bass, Chris still managed to comprehend the point she was making. It wasn't something he thought of before, but it made complete sense. If Sarah asked him to try something new, and if he thought it would bring her pleasure, he'd be more than happy to try it. So it followed that Sarah would probably feel the same way.

"So the only thing you really have to ask yourself is, 'Will you enjoy it?'" she reached a small table and stopped walking. Catherina reached out with her hands to rest on the table and bent at the waist. Her skirt enticingly slid up her delicious rump. "Fortunately, I am here for you to try it out." She reached back and flipped up her tiny skirt revealing a distinct lack of underwear. "Come spank me."

The situation in front of Chris triggered a need within him. He took a step forward. He wielded the paddle with an unnatural familiarity. There was a woman with her ass exposed and the paddle wanted to spank her. He wanted to spank her. He continued walking forward, closing the gap between the two of them, but as he reached out his free hand to caress Catherina's bare ass, a resounding voice from within him yelled, "STOP!!" It was inaudible to everyone, but it snapped Chris from his haze and he recoiled his hand.

"I don't..." he stammered, "I shouldn't... Sarah... What would-?" Chris turned away.

Catherina's head dropped and she sighed heavily. "Chris, my dear, you are trying to buy a present for Sarah, right?" Even with his last ounce of will power, Chris still couldn't **** himself to walk away. He was there to buy Sarah a present. He needed to find her a present.

"And you think she'd enjoy being spanked, as long as you enjoy spanking, right?"

Chris agreed. Catherina wasn't wrong about anything, but could he really spank her? Wouldn't that be like cheating on Sarah?

"So you need to know if you like it first. It's just product testing. If Sarah was here, I'm sure you'd test it on her, but this is a gift. You want it to be a surprise. She'll just be happy you put so much thought into a present for her." Catherina was still bent over the table, her head facing away from Chris, but she knew he was still there listening.

And Chris knew that she was right. That's all this was. Product testing. He needed to know if it was the right toy for them, and what better way to know than by testing it out? He tightened his grip on the paddle and turned again to face Catherina. Her ripe ass was being offered up to the paddle, and he wanted to take it. His hardon raged inside his shorts, and her glistening pussy let him know she was horny as well. He made up his mind.

Whap!

"Oh, shhhh-it..." hissed Catherina.

Chris was amazed. The feeling, the sound, it was amazing. The way her body tensed up, and then released. His cock spurt forth some lubrication and he watched as a solid red mark slowly appeared on Catherina's ass. It had woken something fierce, something primal, inside of Chris.

And he loved it.

"Please," Catherina whimpered, "Will you spank me again?"

Chris smiled.

Whap! "Fuck!" Whap! "Shit!" Whap! "Christ! Fuck! Shit!"

He reached out his free hand and placed it on her ass. All of his attention had been given to one ass cheek, and he could feel the heat emanating into his hand. Catherina whimpered at his touch. Her ass twitched in response.

Slap!

With his empty hand, he spanked her other cheek. He watched with glee as a red and white hand print emerged on her perfect ass.

"Ah!" she squealed, "Shhhiiiiit."

"Good girl," Chris heard himself saying, "Do you like that?" Catherina nodded feverishly. He could see her pussy was dripping now, ready to get fucked. **** for a cock.

"Please, Sir," she whimpered, "Can you spank me more?"

Chris liked that. He enjoyed being called, "Sir." He relished the power his paddle had over her. "Only because you asked like such a polite slut," he responded. The words seemed to just spill out of his mouth without his brain's approval, but his cock seemed happy about it.

Whap!

Chris set the paddle down beside Catherine's head. He gently laid his hands on her ass cheeks and began softly stroking them. His knees bent and he sank down until his face was just beside her ass. The smell of her wet pussy wafted through the air. It smelled delicious, but Chris knew there were more important things to tend to. He gently blew cold air over her ass cheeks. A shiver ran along her skin in response, and he watched as tiny goosebumps spread across her butt.

"Ohhh..." moaned Catherina. Chris began kissing her red, hot ass. Each finger print he had left on her was sealed with a kiss. All the while, his hands gently stroked and caressed her tight butt.

"You're quite a natural," she said with a slight chuckle.

"Thanks," said Chris. He started becoming aware of his situation, not so much in an air of infidelity, but more that his test session was coming to an end. He stood up and backed up a few steps, allowing Catherina the room to stand up and turn around. She flipped her red skirt back down and wiped an errant tear from her cheek. Her hand reached out to grab the paddle from the desk behind her.

"So, what do you think?" she asked, "Is this the right gift?"
