Nothing; for now

"Well, that was fun," Heather said, as she pulled her thong back onto her hips, running her fingers along the small straps. She reached for her shorts.

"But..." Zack looked down at the bulge in his own pants.

"We aren't doing this for you to get off," Heather smiled as she pulled up her shorts. "We're doing it so you'll learn. Now, we've already been gone too long for just a simple hike. Let's get back."

Zack knew that wasn't the only reason. He could see Heather's smile. She was teasing him, again. God damn it, he'd eaten her out, and she was still teasing him. They were back to square one.

"Come on, Zacky," she said. He hated her calling him that.

He got up, sighed, and followed her back to the cabin.

By the time they got back, it was the late afternoon, and Gavin was still outside playing video games. Zack expected him to ask why they'd been gone so long, but instead, he stayed mum and kept playing on his phone. Instead, Zack decided to take the initiative.

"So, Gavin," he asked. "Anything change while we were gone?"

"Uh...well," Gavin thought for a second. "I made it to level fifty."

Zack sighed. Heather smiled, again.

"What about everyone inside?" Zack asked.

"Oh," Gavin said. "Brandon and Ashley went on a hike."

"Jeez, you'd think those two would get tired," Heather said.

"Seriously," Zack couldn't help but smile. "What about Chloe?"

Gavin shrugged. Then went back to playing.

When Heather and Zack entered the cabin, the first thing they saw was Chloe, on the table, looking extremely awkward. The second was Kurt and Victoria sitting on the couch, just about to kiss. They stopped the moment that the door closed, as if Chloe's presence, alone, hadn't been enough to stop them. Zack couldn't help it, his fist clenched.

"Hi Zack, Hi Heather," Chloe said. She waved her hand. Her face sent the message: thank god you're here.

"Hopefully we aren't interrupting anything," Heather said, in a tone that made it clear she was very happy to interrupt.

"Oh, screw off," Kurt said.

Victoria slapped his shoulder playfully. Flirtatiously. Zack thought he was going to bite through his jaw.

"That's an awful way to treat your cousin," Heather said. "Especially when I'm still the hostess."

Kurt shut up.

"Where were you?" Chloe whispered to Zack.

"Hiking," Zack whispered back. "Is this the first time they've kissed?"

"Yes. Thank god you interrupted it. It was awkward enough with how they were flirting."

Zack cooled down a little bit at this information. He looked over, and saw that Heather was turning on the television.

"Well, between swimming and hiking, I think I've had enough for one day. Let's all just sit around and watch tv," Heather said, and smiled back at Zack. He could swear she winked.

Looking at Heather and Victoria, Zack suddenly started to feel something. Not guilt, he couldn't cheat on someone he wasn't dating. But he was worried that if he continued on this path with Heather, Victoria would just drift further and further away. Just now, when they'd left her with Kurt, the two of them had almost started making out. And what if she found out about what he'd done with Heather? She might misinterpret that; and assume that he was interested in her instead.

Zack's head hurt. He sat down and watched TV.

At some point, as the hours passed, Brandon and Ashley came back, glowing. Zack didn't need to guess what they'd been doing. And he felt a surge of envy. It was so easy to be out on a Spring break vacation with someone you were dating, and spend all your time having sex with them. Especially in comparison to what he was going through.

When they sat down to eat dinner, Heather insisted on sitting next to him, even moving Chloe out of the way to do so. Chloe, puzzled, didn't argue, but did shoot a glance at Zack. Heather smiled at him, then took out her phone, and started texting. She put it away after she'd finished.

As Zack started to eat, he felt something vibrating in his pocket. He pulled out his phone, and looked at the message. It was from Heather, and it was very short:

Lesson 2: Keeping your cool when aroused

Just then, he started to feel a hand worming its way along his leg. He looked over at Heather, but she wasn't looking at him. And, from above the table, there was no sign that she was doing anything other than resting her hands on the side of her chair.

"Is something wrong, Zack?" Victoria asked, across from him.

Zack turned and saw his crush, Kurt's arm draped around her, raising her eyebrow at him.

"Uh...what?" Zack asked.

"You were staring at Heather," she said.

"He was?" Heather said, her hand slithered further across his thigh. "I didn't notice."

Zack looked between Victoria and Heather. If he was going to do something to stop Heather, he had to now. Otherwise, he knew where she was going to grab him.
