A few hours later

A few hours later, Heather was laying on the couch with Zack, one of his arms around her shoulders.

Gavin was in the room, and he found it nearly impossible to keep his eyes off Heather.

After their sex-filled shower, Heather and pulled on some very tight clothes that showed off her curves and large breasts.

Just to tease him, Gavin guessed.

“It’s too bad Elle’s not coming. I feel bad that you’re all by yourself.” Zack said into the quiet living room.

“Oh, yeah, it sucks.” Gavin said, startled. He hadn’t thought about Elle in quite a while, he realized. His thoughts had been consumed by Heather Ravers, in her little cotton short shorts and her green, low cut crop top.

Zack looked up as Hannah walked in dressed in a pink tank top and skintight jeans. She gave Heather a huge, teasing smirk, and then Gavin’s cock went from half-hard to hard as he watched Heather and Hannah, the two busty beauties, kiss.

They kissed in a sexy, sloppy way, Gavin noticed. It was amazing to watch. Then Hannah pulled back, pushing blond hair out of her face and smiling down at Heather.

Heather gave Hannah an adorable smile, and the blond came over to sit down in an armchair.

Zack and Gavin were both hard from the two girls’ kiss, and Gavin was pitching quite the tent in his shorts. He glanced over subtly at Heather and found her icy blue eyes aimed at his very visible erection.

Zack was engrossed in chatting with his old crush, Hannah, and had no idea.

Gavin swallowed at the seductive look Heather gave him, and realized he wanted to fuck the cheerleader right now. Badly.

“I think I’m going to go for a walk.” Gavin announced, rising to his feet.

Gavin locked eyes with Heather as he walked out onto the back deck, down the wooden steps, and across the grass out to the pier by the lake.

He sat down on the end of the pier, and hoped Heather would understand what Gavin wanted. But he had to go first, because Heather was assuredly a much better liar than him. Going for a walk was innocuous but coming up with an innocent reason to accompany his best friend’s girlfriend on a walk was much harder.

Gavin waited on the pier for probably thirty minutes. He pulled his phone out after five, and played a game on his phone.

Just when he was about to give up and head back inside, Gavin saw her.

Heather Ravers.

The sexiest girl in school, wearing a deep red bikini that covered nearly nothing. She had sexiness in her walk as she walked across the grass and down to the pier.

“I thought you weren’t coming.” Gavin admitted.

“I had to make it believable.” Heather apologized.

“Don’t worry about it.” Gavin said as Heather sat down in his lap, facing him. Gavin wrapped his arms around Heather’s waist and kissed his best friend’s girlfriend.

Her big tits looked insane in her sexy red bikini top, and Gavin wanted his hands all over her melons.

“This cheating on Zack… I only planned for it to last a few days.” Heather confessed, “You made me feel so incredible during Truth or Dare, and I told myself that I was just helping you have fun until Elle got here. But… but now she’s not coming.”

“Does that mean we’re done?” Gavin asked, worry in his chest.

“Oh, definitely not.” Heather cooed, rubbing Gavin’s arm.

“Then… I mean, aren’t you going to tell Zack at some point?” Gavin asked.

“Tell him what? That his nerdy looking best friend fucks me better than he does? No, I’m not going to say a word. And I don’t want you to either. Besides, so long as I’m dating your best friend, you have my body on speed dial.” Heather teased.

“Do I?” Gavin asked thoughtfully. Heather gave him a sultry smile.

“Why don’t you find out?” Heather purred.

———

Taylor Bishop stood at the tree line by the cars and watched as her brother’s best friend and her brother’s girlfriend fucked out on the pier.

Taylor was far back, so she didn’t have the best view, but it was very obvious even from afar that Gavin was absolutely brutalizing Heather’s pussy.

He had the cheerleader on her back, one of her legs lifted up in the air while he pistoned in and out of her pussy feverishly. Gavin’s other hand was on Heather’s big tits, clearly working some magic on the busty dark haired girl.

Taylor found the whole scene incredibly hot. She’d never thought much about it, but seeing a cheating couple fuck was shockingly arousing. The fact that the girl in question was cheating on none other than her little brother made things strangely more hot. Taylor’s pussy was damp right now, and her hand felt like it was magnetized to her pussy, despite her not wanting to finger herself again.

Taylor felt bad for Zack, and knew he would be devastated when he found out, but at the same time, she hoped he never found out. Knowing Heather and Gavin were screwing behind Zack’s back got Taylor all hot and bothered.

Taylor realized something abruptly. She could help cover for Heather and Gavin whenever they snuck off together for a fuckfest. Taylor could hardly believe the thought. She would be helping her little brother’s girlfriend fuck his best friend.

Taylor’s thoughts then turned to Gavin. If he could satisfy Heather Ravers, he was surely an incredible fuck. He had groped her tits during the Truth or Dare game, and Taylor had loved that, but she realized abruptly that she could get more of him.

What a winner Gavin would be, then, to have both his best friend’s girlfriend and his best friend’s sister fucking him.

Taylor’s thoughts strayed to how good Heather would be in bed, and she found herself orgasming in the grass, her free hand hastily trying to clamp over her mouth to stifle her raspy moans.
