"Please, Yelena, I need a moment to think," Kate said, excusing herself, looking at you on the table for a moment before turning her back on you.
You were so focused on the gigantic archer in the room that you didn't even notice Yelena's approach until her shadow was already on top of you. The blonde-haired Russian towering over you, forcing you to compare her to the likes of one of New York City's many skyscrapers, with the table-top barely reaching the height of her hips.
Looking up at this massive woman, you found yourself completely terrified by the sight of Yelena looking back down at you. Her eyes had turned cold, sending a shiver down your spine. She had talked about doing it, but was this lady really about to crush you like a bug?
You resisted the urge to run, worried that Yelena might swat you like a mosquito, and then claim to Kate that you tried to run, and she was concerned about you telling someone else about her shrinking you.
Luckily, Yelena's intentions were not so cruel. She was, in fact, happy that Kate turned her back on them so she could have a little fun at your expense. She raised her hand over you, and you began to run towards the edge of the table towards the girl who shrunk you.
Almost positive that this blonde assassin was about to end your life, you yelled for mercy, "Kate, please turn around, help me." but Yelena's hand quickly cut you off as she slammed her open hand down in your path, forcing you to run directly into her palm.
The blonde Black Widow assassin curled her fingers into a fist, with you at the epicenter, surrounded by her powerful fingers. You were unable to see outside of your new prison as she quietly snuck up on Kate to plan a practical joke on her.
Kate, lost in thought, didn't even realize Yelena was behind her. That is, until her new 'friend' pulled open the back of her pants with a forceful yank of her right arm, depositing something into the back of her panties.
"Yelena, what are you..!?!?" was all Kate could stutter in response as she looked over her shoulder to see Yelena standing there with a joyful smile displayed across her face. Her eyes darted to your last known location on the table, further surprising her when she saw that it was barren.
One moment, you were surrounded on all sides by darkness, and the next, you were looking down at a gigantic butt. But who did this massive booty belong to, Yelena? No, as you fell, you caught a glimpse of her depositing you into the giant's backside. Which meant the giant booty had to belong to Kate.
Kate's voice above you confirmed this suspicion as you bounced off her gigantic butt, rolling down her panties until you finally fell between her buttcheeks.
"Yelena! What did you do? Where is he?" you hear Kate yell, concerned with your safety, her frantic mind not putting two and two together as the Russian giantess glanced down at you.
"Please, let me out of here! I-" Was all you could utter before Yelena allowed Kate's pants and panties to snap back against her skin, doing all the work of keeping you in place for her.
"Kate Bishop, you really can't tell where he is?" Yelena asked, allowing Kate to follow her line of sight back to the archer's backside.
"You didn't." Kate scolded, turning around on her heels to face Yelena while still aware that she had you trapped up against her butt. However, for some reason, Kate didn't immediately choose to retrieve you from the chasms of her buttcrack as her movements forced you deeper into her panties.
"Hehe, I did. You have to admit. It will be easier to keep an eye on him now. Do you like it? I got the idea from American movie I saw last night." Yelena declared, not feeling the need to defend her actions.
"But, why did you drop him down the back of my underwear?" Kate asked, able to feel your struggles against her butt.
"Well, you need to be able to take him outside of the apartment, right? I know I'm not an expert on what's 'normal' here but carrying a tiny person is weird, even for me. Keeping him against your butt is smart move. And besides, I doubt he minds. It's a cute buttock." The Russian woman laughed, complementing Kate's figure.
"Really? Do you think so? Hey, no compliments, you can't go tossing people into my butt, no matter how cute it is." Kate said, checking herself out in a nearby mirror. She couldn't see any trace of you on her butt, meaning she was free to take you out in public while she tried to return you to your human size.
"Fine, he can stay back there for now, but next time give me some warning before you pull a stunt like that." Kate asserted.
"Next time? You assume this will happen again?" Yelena teased, hoping she wouldn't have to drop more than 3 or 4 miniaturized people into Kate's clothing.
"Wait, are you really not going take me out of here? Kate! KATE!" you yelled, your voice lost in the valley between the gigantic young woman's ass.
What will happen next?
1. Kate leaves you in her butt, while she and Yelena talk about long-term solutions to shrinking you.
2. Kate separates from Yelena, going off on her own to find someone who can help her return you to your human size. Hope Pym.
3. Yelena claims Kate is too stressed out and recommends that they have "American girls night" to help her relax.
