More lessons.

Chloe couldn't help but feel a twinge of jealousy as she watched Rachel and Max's intimate moment, but she quickly shrugged it off, reminding herself that this was all for the sake of their friendship and her own education. Plus, she had Rachel's hand to keep her company, and she was definitely not opposed to the idea of Rachel helping her with her homework in the same way.

Rachel broke the kiss, her eyes shining with excitement. "Now, let's get back to those equations," she said, her hand sliding down to trace Max's still-quivering thigh.

Max's eyes snapped back to focus, a blush spreading across her face. "Right," she murmured, her voice husky with desire. "Math."

Rachel sat back up, her hand still resting on Max's thigh. "Where were we?"

Max took a deep breath, trying to regain her composure. "Um, equations?" she said, her voice still shaky.

Rachel laughed. "Right, equations. Let's tackle these bad boys together." She leaned over to grab a notebook and a pen, her breasts pressing against Max's back as she did so. The contact made Max's skin prickle with sensitivity, and she had to bite her lip to keep from moaning.

They spent the next few hours working through math problems, with Rachel occasionally reaching around to give Max's ass a gentle squeeze or light smack, reminding her to stay focused. Chloe watched them, her own arousal building as she thought about the spanking she would receive if she didn't keep up her end of the bargain. Rachel's touch was firm but caring, and Max found that she was actually learning more than she ever had in a traditional classroom setting.

As the night grew later, Rachel suggested they take a break. "You two must be tired," she said, stretching her arms over her head. Max and Chloe nodded in agreement, their bodies aching from the unconventional study session. Rachel stood up and offered her hand to Max, helping her to her feet. "Why don't we head downstairs for some snacks?"

They padded down to the kitchen in their bare feet, Rachel's hand lingering on the small of Max's back. The warm glow of the lights made their naked skin seem to glisten as they rummaged through the fridge. Chloe grabbed a bottle of water, her eyes never leaving Rachel's ass as she bent over to grab a bag of chips. Rachel turned around, catching Chloe's gaze and wagging her eyebrows playfully.

"You know," Rachel said, popping a chip into her mouth, "I think we're onto something here. This could be the new way to learn."

Max chuckled, her cheeks still flushed from their earlier activities. "Yeah, I've never been so motivated to solve for x."

Chloe took a swig of water, her throat feeling parched. "It's definitely more interesting than reading textbooks."

They sat around the kitchen table, munching on chips and sipping on sodas, their nakedness feeling natural and uninhibited. Rachel reached over and grabbed another handful of chips, her breasts bouncing slightly with the movement. Max couldn't help but stare, her eyes drawn to Rachel's nipples that were now erect from the cool air in the room. Rachel noticed her gaze and gave her a knowing smile.

"You know," Rachel began, "I think we should make this a regular thing. I mean, if it's working for us, why not?"

"Yeah," Chloe agreed, leaning back in her chair. "But we need to be careful. We don't want anyone finding out about our little...study method."

Max nodded, her eyes darting between Rachel and Chloe. "Agreed. But I can't help but feel like we're crossing a line."

"Don't worry, Max," Rachel said, her voice reassuring. "We're all consenting adults here. And it's not like we're hurting anyone."

"I know," Max replied, her voice a mix of doubt and excitement. "It's just..."

"It's just that you never knew you liked it until you tried it," Rachel finished for her. "And that's totally fine."

They sat in comfortable silence for a few moments, the only sounds in the room being the crunching of chips and the occasional clink of ice in their glasses. The tension was palpable, a mix of anticipation and the unspoken promise of what was to come.

"So," Rachel said finally, breaking the silence. "Who's up for round two?"
