Back in the cafeteria...

You only ate a little bit of cake, a couple of handfuls, which for Lillie appetite standards was barely a morsel but you saw that Jim ate enough to make a dent that'd be visible to Brobs. Only now you stopped to realize that maybe being able to figure the way things would look to Brobs was a skill most ordinary lillies wouldn't have, maybe you needed to be careful about that to not give away your peculiar nature.

"Hey Jim, are you sure you wanna fill up on cake only? The school app says we get a meal at 5 and that's just in like 15 minutes or so" You asked. Maybe it was because of how you were raised because your parents didn't consider stuff like pastries or snacks as "real food" to consume if actually hungry. They weren't against those at all but they simply taught you that it was best to sate actual hunger on more proper food meant to nourish the body.

"Hah! I already burned it!" Jim said, boastingly patting his flat stomach. It was true, by looking at him, no one would've been able to tell the guy had just consumed like 20% of his own weight in cake & frosting "Man, that booty bombing with Lulu took a lot out of me, you owe me big time!"

"Yeah, yeah, just don't eat yourself into a sugar coma or something. You have to be alive for me to pay the favor back after all" You replied, chuckling as you rolled your eyes. Sometimes even the friends that you'd known for most of your life could still surprise you.

"Huh, so that explains why lillie girls all seem so skinny" Cindy nonchalantly noted. Jen blushed, a bit worried you and Jim would take offense but sighed quietly in relief when she saw no change in your expressions.

"Yeah, lillies struggle quite a lot to put on weight. Guys too, it's pretty hard to bulk up" You said but then Jim walked a few steps closer to you and put a hand on your shoulder.

"Then how did you do it?" He asked with a cheeky smirk "Yeah, most lillies have twig-like arms and legs. Hell, I can't say I have too much meat on my bones for that matter... how come you do?"

You froze for a moment. Being a hybrid yourself, you did some reading up on what makes them different from regular lillies and among things like different hair colors such as yours being black, being taller and having a less slender frame were traits noted to be present in Lillie-Brob hybrids, to a lesser extent in Lillie-Gullie ones too. But obviously the girls wouldn't know unless pointed out.
'What the hell, Jim?!' You thought while trying your best to remain calm. You were far from being considered a beefcake or being on the level of professional weightlifters but it was true that you had a sturdier build than the elfish-looking average lillie. Your dad had even more pronounced muscles, partly attributed to him being half-Brob himself and in part due to living around Brobs for so much longer than you, being capable of doing things like cooking Brob-sized meals even.

"I'm just kidding!" Jim then said, sparing you from having to cook up some half-baked excuse on the fly "I guess most would have some more muscle to show for it if they had a big sister that's a gym nut"

"Yeah" You laughed nervously but when you glanced up you saw that both Jen and Cindy had been staring at you very intently, seemingly in a stunned silence. You couldn't help but flinch, practically feeling their gaze piercing into your body, prompting you to take a look at your clothes, they weren't even too form-fitting, a simple t-shirt with a jacket on top for some protection against the cold and plain jeans. Looking again at Jim... yeah, he looked slimmer than you were but you didn't think it'd be all that noticeable.

"Oh yeah, you said your sister's pretty strong" Jen said with a smile.

"I'm gonna go on a limb with this take but if you call her strong for lillie standards I can't help but think of her as a literal superhero. I can picture moving faster than the eye can see and I dunno, maybe being able to pick up and toss some Brob-sized objects?" Cindy said.

"Ah, well... she's very strong indeed" You chuckled. There was no way you could tell them that your big sis was a Brob like them, though in all fairness, she was notably taller than most and boasted pretty impressive muscles on her arms plus chiseled abs, yet her boobs and butt were easily on par with Jen's and Cindy's.

"Well, maybe one day I-" Jen was saying but she stopped herself for a split second, trying not to sound too bold before continuing "I mean, we can get to meet her, she sounds like a cool person"

"Sure, sure, maybe one day" You laughed nervously, scratching the back of your head.

"By the way, you didn't eat as much as Jim. Don't like chocolate?" Jen asked sincerely.

"I love chocolate!" You replied a bit too eagerly "I mean, I prefer drinking it but still. Nothing wrong with the cake, it's amazing! But if I feel hungry I prefer eating a proper meal and then have a bit of a dessert after" You then explained.

"Wow. I think that now I understand what being raised right is like" Cindy giggled.
"If I could, I'd be eating dessert all the time! Should be obvious, huh?" She playfully winked at both you and Jim before patting her round belly.

"W-What can I say? I don't like getting in trouble, listening to my parents and grandparents was the easiest way..." You said, a bit worried this might damage your reputation too much but rather than mockery or disdain, you saw a certain gleam in both girls' eyes but more strongly in Jen's, who giggled softly as she leaned down and closer, with her enormous chest in view. It was like seeing 2 bouncing mountains floating in the sky, looking as incredibly soft as they were heavy, looming in a way that seemed like they could suddenly drop down at any time and squash everything around you, covering an area comparable to several lillie-sized city blocks.

"But sometimes getting in trouble can be fun~" She whispered, instantly giving you goosebumps all over. Unseen by you, Jim was blushing as well but he gave Jen an enthusiastic thumbs up.

"N-Not gonna deny that" You said, but weren't sure at all how to respond. Jen seemed to be way too playful than she appeared. It's not like she was really into you, right? She must be just curious about lillie boys, surely.

Similarly, Jen was almost freaking out on the inside, she was surprised at herself, at how bold she was being. She really liked you but normally she'd be more shy than that. And yet, there was something inside her, something that made her feel like she'd had a crush on you for way longer than just a single day, though she couldn't exactly figure out why. Attempting to pry further into that line of thought resulted in nothing more than headaches, discouraging from trying to dig further into it.

She had seized the moment and Jim's thumbs up only made her feel even more confident, in spite of her little bit of hesitation inside. Remembering his advice, she figured that she should use her chest to seduce you but how? She wanted to just pick you up and drop you into her cleavage and then make some playful remark but she was shooting blanks in her mind. Glancing at Cindy, she envied her a little, not only she had a bigger butt than her own but she was also more nonchalant than her, resulting in inadvertently having uncanny levels of self-confidence, similar to Lillian's but keeping her adorable & dorky vibes.

But before she could reach for you and enact her half-thought plan, they heard and felt someone's footsteps rapidly approaching and much to her annoyance, it was precisely Lillian, her bestie but also her current romantic rival. Lillian looked much more refreshed now than when she hurried off to the bathroom, her tummy, noticeably pudgy but smaller than Cindy's didn't seem as bloated anymore.

"Oh, we got dessert already?" Lillian said, hungrily eyeing the cake.

"Dolores gave Jen that cake to share while we wait for dinner" Cindy explained and was about to reach for the tupper with the remaining 2 slices but Lillian swiftly dashed to the table and sat right next to Cindy, her bodacious Brazilian booty making a noticeable THUD! that both girls felt.

'That ass is no joke' Jen thought but then her eyes widened when she realized what was about to happen. Cindy got the same realization a split second later and the two turned to Lillian, sensing a spike of panic as she looked like she was about to start eating the lone cake slice and they both knew she could demolish entire cakes in very little time.

"Lillian, NO!" Both Cindy and Jen screamed while Lillian herself froze in her tracks and gave them a raised eyebrow, finding their reaction too exaggerated.

"What?" The larger beauty said but with a cheeky smile and then raised the whole plate the cake slice was on "Is it because this slice got some special sprinkling?" She giggled and this time it was Cindy's and Jen's turn to be confused.

"HUH?!" They both said in unison.

"You thought I was gonna eat our friends, didn't you?" Lillian chuckled, gently setting the plate back on the table "Not gonna lie, I didn't see them at first but I noticed that it was odd, you had this plate and this slice of cake in front of an empty chair and there's no signs of Zuemy, so if this slice was neither yours nor Cindy's nor Zuemy's and I had just arrived there was only one conclusion: That you had the boys on that slice so they could eat too"

Jen and Cindy blinked twice in surprise, looked at each other a few times and then looked at Lillian, feeling weird in a way that neither could describe too well.

"You know, sometimes I wonder how you don't get better grades when you can be smart like that" Jen said with a slight giggle.

"Yeah, you totally pulled a Zuemlock Holmes right there" Cindy smiled.

"A what now?" Another voice echoed lightly around the largely empty cafeteria and all 3 girls turned to the direction it came from. Zuemy smirked and confidently walked to join the rest at the cafeteria, carrying a now awake Joel on her chest, just barely inside her cleavage...
