It turned around, and you saw a Stunky! The Poison type looking at her friend, and smiling. "Princess! There you are!" You heard her voice, and it was a girl. She ran over with a big smile, jumping around. "What are you doing here, are you breaking into this house too... we better get out of here before the owner comes back~"
"Oh we don't have to worry about that." She smiled. "This is the owner right here." You were hiding behind Glameow, as a paw was behind you and forced you forward. You didn't have a choice as you were presented.
The Stunky was looking down at you, as you give a nervous wave up to her.
"This is (Your Name), and this is Stella. He's the human, he shrunk."
"Wow... he shrunk." She walked to you, and you smile nervously to the giant Pokemon. "He's so small, he can't scare us out at this size."
"True." Princess smiled. "Which is why I live here now, this is my home." Princess smiled and the Stunky was excited.
"Wow... so this is your place, as in the whole house, and all the food!" She ran past you to check the house, as Princess curled around you with her tail. Holding you and forcing you to walk with them.
"W-Who is that Pokemon?"
"She's a friend, if it wasn't for her I wouldn't have survived the slums." Princess smiled. "And I taught her the beauty of using a sponge to actually clean yourself." She walked and the skunk Pokemon was running around obviously excited. She seemed younger than Princess, and never lived the highlife like her.
Princess jumped onto her couch, and got ready to watch TV.
"A-Aren't you going to kick her out!"
"I would rather kick you out." The Normal type smirked as you grumbled in return to the giantess.
Stella walked back in with a large smile. "Can I stay here too."
"No!" You shout, as Princess then put her paw down on top of you. Leaving you flattened and buried.
"Yes, you may." Princess said.
"W-What, but he sai-"
"This isn't the human's house, it's mine. I get to decide if you stay, and I say yes."
Stella smiled. "Oh thank you Princess!"
"You can't just invite Pokemon to live here."
"I think I can~" The Pokemon teased and you grumble in return. "But Stella, it's my home. So I'm in charge, you can be second in charge. The human has to listen to both of us."
"Fine by me. I'm going to get more food!" Stella ran to the next room, using her small legs as Princess giggled.
"So cute," She chimed obviously enjoying herself. She lifted the paw as you roll around and look at the giantess. You were not too happy looking up to her. She just laughed it off, giving a wink to you as she was so happy.
You look at her as well, before standing up.
"No... paw rub." She ordered as she put them in front. "Now~"
"You give my home away, and now you want a paw rub."
"Do it."
"No."
"Do it." She teased leaning over to intimidate you.
"No." You grumble even louder giving a frown to the Pokemon. Then she lowered her paw down onto you. Leaving you flattened as she laughed. She then rubbed her paw on top, making you feel a bit hurt to which she laughed at. She shook around side to side, enjoying herself.
This lasted for a while, as she forced a paw rub on you, AKA she was rubbing her paw on top of you!
She stopped laughing at you as she was able to relax.
Stella came back, with a cookie in her mouth as she then leaped up onto the couch. It wasn't as easy for her as it was for Princess, but she got up.
"This place is amazing, thank you for letting me stay." The skunk turned around, and her rear was over you.
You didn't have enough time to piece it together, before the butt then came down onto you. Your eyes went wide, as you saw her tail raise and the skunk was going to sit on you!
You were flattened and buried under the cheeks, stuck and unable to do anything about it. The Pokemon enjoyed herself as she sat on her rear and ate.
"You are sitting on him." 
Stella chuckled, and this got her to realize. "Oh, you want me to get off your Human."
"No." Princess chuckled. "He was a bit rude, he can be under your butt." There was a grumble from under the butt, as Stella giggled.
"So you can do like... whatever you want here, and whatever you want with the human. That sounds amazing!"
"And you can too Stella." Princess smiled to the younger Pokemon, who was so happy and excited.
For you, you were in hell. Being sat on by the Stunky, her butt pinning you down as you can't lift it off.
And my god.. the SMELL! She was able to cover it up most of the time, but you were literally under her butt, the smell was in your nose and you were hating it. Your face was cringing and you were so disgusted! It smelled terrible, Poison type was right! You struggle and tried to lift Stella off of you, trying to save yourself at the very least.
All you were getting was a giggle from the giantess as she found it too funny. You were stuck under the butt, and forced to endure the terrible smell.
Even worse, she can take it a bit more. If she sprays and farts, it is literally like a blast of Cyanide straight into your face, even Princess would feel bad for you if that happens.
And Stella didn't have the best control of it, giggling as she kept on eating the cookie and Princess kept watching the TV.
The whole time, you were still tempting fate.
