Inoue Orihime, only wearing her underwear consisting of a bra and panties, forces the somewhat smaller Rukia on her back with the help of her extra weight, contributed by her breasts.
With a light thud, Rukia lands on Inoues bed. Before she could realise what was going on, Orihime jumps her and places herself on top.

"What are you...?" Rukia mutteres before being silenced by Orihimes breast. Quickly, Inoue wraps her fingers around Rukias whrists, prohibiting her from fighting back.
Her tight and warm cleavage is suffocating Rukia and with her arms in check she has no way of fighting back.
Orihime smiles while Rukia does her best to escape, "I'm going to teach you a lesson, Kuchiki. A lesson who is the strongest here".
Like a villainess she laughs in pleasure as she feels the body of Rukia slowly growing weaker of oxygen deprivation.
"As soon as you're defenseless, I'll have you kissing my feet. And if you refuse, I'll just beat you up some more".
Rukia tried struggling but found that her movements were completely sealed by Orihimes body. She couldn't even turn her head which was as stuck as could be between her large breasts. She felt her body go numb and realized she would lose consciousness now.
But, to continue the humiliation, before Rukia could pass out, Inoue lifted the viselike grip of her boobs from her and placed her but on Rukias stomach, using her as a sitting pillow.
Rukias face was red, almost purple, and she didn't even have the power to try and push the larger girl of. She was just lying there, defeated.
