Oh shit

The boys made it home without much trouble, but pretty much the entire bus was staring at their massive asses and bimboy lips. Getting through the door and into the home they were staying in. Both boys letting out a groan as Zeke headed up for the room, Zhane heading for the fridge only to widen his eyes. Zhane looking through the fridge as carefully as he can, only to let out a "FUCK!" a few minutes later, closing the fridge and resting his head against it.

Zeke came back to the kitchen hearing that. "What happened?" Zhane pulled his forehead off the freezer door and turned to him. "So remember those purple Serums I made?" "Yea?" "Okay well I put them in the fridge this morning so they would be safe right? Guess what's missing?" Zeke's eyes widen as it sinks in. "Oh fuck..." "Yeah..."

With that both boys went downstairs to the basement, Zhane heading for his equipment with Zeke helping him run experiments and recreate the serums that were now gone. It took awhile but thankfully right around Dinner time Zhane was finished, Zeke helping out however he could before finally they came back upstairs. The boys found food on the table, delivery it looked like, along with a note explaining that the mother and daughters of the house were feeling weird so they'd gone to bed early. The boys ate their food and headed to bed, trying to carefully prepare themselves for the next day of school and already looking forward to the weekend.

The next day both boys woke up early and got themselves dressed before heading down to munch on at least a little something before school, only to stop and freeze as they stared in shock. What did they see? The mother and her daughters all downstairs finishing getting ready to head out for the day, normally that wouldn't be shocking but um... they each seemed to have had a growth spurt. It took only a few moments for Zhane to realize that they had drank the serums yesterday at some point.

The mother previously an 8ft tall anthro was now a TOWERING 12ft tall, her bulge more than DOUBLE it's original size, her other assets having grown and swelled massively which was only made more clear by her dress straining to hold itself together. Her daughters though had grown as well, not a single one of them under 10ft tall now, their own bulge having gone through a monstrous growth spurt. Mother and daughters each having grown some huge powerful muscles as well by the looks of things, each of them turning to see the boys having come downstairs, seeing the changes the boys had gone through made the pants and skirts stretch even further, the family's clothes threatening to tear apart as they each eyes the boys like tight fuck sleeves to reshape and mold to their aching cocks.

"Oh my~! I see you boys went through a growth spurt as well~ You look simply AMAZING boys~" The mother spoke out, her lust BARELY held back from entering her voice. Both boys so stunned they couldn't bring themselves to ask HOW these gorgeous futa's had grown sooo much. The boys were sat down at the table and given some food as the family left, trusting the boys to lock up as they had yesterday.

The boys ate in silence, both of their massive asses twitching and tingling as neither boy could get the thought of those bulges out their minds. Finally the boys finished and took care of what they needed before heading for the door, locking up on their way out. "So..." Zeke started as both boys began moving towards the bus stop. "They took the serums and grew..." Zhane continued, Zeke nodding his head as both boys looked at each other, gulping as they tried to prepare themselves for what the day would hold.

"That accounts for ALMOST all of them, unless one of them has a second serum they just haven't used yet... What do you think?" Zhane asked Zeke, both boys thinking about the possibility as the bus finally arrived. "Kind of hoping it's just one of them that has the 5th serum honestly, safer with them than with someone that could figure out how the stuff works right? Don't need your research being stolen." Zeke responded, both boys nodding their heads as they got onto the bus.

Each boy gulping as they thought about the futa's at the school, both a little afraid that they would be trapped, caught, pinned or punished again today. Only to slowly grow MORE concerned as they realized that if they WERE fucked more at school today... then they'd be heading home as even bigger, sluttier looking boy sluts. Both boys already needing new clothes and currently only able to wear skirts that barely hid even half of their asses along with some tops that were thankfully loose on them.
