Someone wants in on the fun!

Liz made a decision. She knew that her brother got aroused at the sight of her massive muscles, breasts and cock, but she knew deep down, that it could never be a serious relationship. Yes, Josh got aroused and she enjoyed teasing him, but Liz knew that Josh would go to college and find himself a girlfriend, and she couldn't follow him. And she liked the sex she had with Athena, so why not?

"Let's make it official, and make it serious," she realized that she had spoken up but kept silent as Athena looked slightly up at her, and nodded seriously, "Fuck them, let them say we're gay, let's see what happens."

Athena smiled, "Cool. Go on a date tonight?"

Liz shook her head, "I need to finish some homework that's due tomorrow. Sorry."

Athena's smile didn't vanish, "What subject?"

Liz grimaced, "Math." She stuck her tongue out and Athena giggled as the larger girl shoved her penis back into her pussy and they slipped their tight panties back on, "And I know Mrs. Walters isn't going to let me get away with it."

Athena looked thoughtful before she nodded to herself, "I'm pretty good at math, I'll come by your house later and help you with your homework." She turned her head to look at Liz, still smiling warmly, "What do you say?"

Liz instantly hugged the older girl, "Thankyouthankyouthankyou!" She replied, "All of that math is really hard!" Athena couldn't help it and started laughing at the exuberance of the younger girl as Liz span her around and before Athena could respond, kissed her full on the lips. After a moment staring at her wide-eyed, Athena responded, her tongue brushing against Liz's teeth and the younger girl obliged as their tongues wrestled each other before they both felt their nipples start to stiffen.

They broke the kiss and Liz was about to suggest that they both head home when they heard a soft, confident voice declare, "I want in."

They turned in shock and Liz recognized the girl standing there in front of them, it was her best friend, "Alicia!"

Alicia Yamada stood there and Liz was surprised to see the determined look on the usually terribly shy Japanese-American; Alicia was always the friendliest girl in Liz's year and class but she was also the shyest, mostly because the first thing everyone saw of her was her naturally massive D-Cup breasts. Staring at them, Alicia repeated herself, "I want in."

Athena blinked, before shrugging, "Sure, I don't have a problem with that."

Liz was unsure, "Alicia, if you have sex with me, you'll grow bigger and you've always been-"

Alicia shook her head, "I want this Liz, I want to grow." She stared right at Liz's eyes with her own blue ones, "I want you to make me grow." She looked away, "I...kinda have a crush on you and when those girls left, and then you stayed...I saw you two having sex..." She glared at Athena, "I wanted to be her first time!"

Athena snorted and started laughing, "Oh this is rich! She's jealous!" She bumped Liz with an elbow, "I'm going home to find some better clothes, you have fun with your girlfriend and I'll drop by to help you with your homework." She glanced between the two and started giggling again before walking out, leaving the pair of girls to stare at each other.

Finally, Liz asked, "Why me? I mean, there's lots of cute guys, you could be dating any of them! Heck, you could even be having sex with them!" The massive girl shook her head, "I mean..."

Alicia stepped forward, "Because you befriended me for me, not because you were some horny boy wanting to stick his dick in me for another notch on his bed, because you knew how to pay the right respects to my mother." Liz remembered that meeting, how Alicia told her that the girl's mother was really strict and traditional and she had practiced the right bow to give and Liz remembered how pleased her friend's mother was, calling Liz a 'dependable girl' after the visit.

Alicia pressed her small, cool hands against Liz's hot abdomen and the larger girl gasped as the smaller girl finished by saying, "Because you saved my life." And just like that, Liz remembered saving Alicia when there was an accident on a school trip a few years ago, her quick thinking preventing Alicia from nearly getting crushed during a tour of a shipping company's warehouse by a falling crate.

Liz suddenly squeaked as she felt Alicia kiss her hard six-pack and blushed hard as she tried to process everything that had happened, before she decided that she needed to get out of the school and fished out her mobile phone, calling Josh.

At the high school, Josh was in study hall when his phone vibrated and he quietly answered it, "Hello?"

"Josh? It's Liz. I'm not feeling that good, can you come pick me up?" Josh immediately started packing his things.

"How bad is it? Is it because of your...you know what?"

"It...it's complicated. Could you come pick me up? Alicia is coming with me as well." Josh quickly explained the situation to the teacher in charge of study hall and received permission to leave.

"Okay, I'm on my way, and I'm going want an explanation."

"Yeah, I know. I'll meet you outside."

Josh sighed as he jogged to his car, "I just know I'm going to regret this."

Meanwhile...
