11pm, with Mia waiting for her

I drop my bags just inside my bedroom door and flick the light switch on. I check my phone - I'd arrived at 45%, which gives me a mild fondling in my revealing pink crop top.

"Woah!" My chest jiggled as I step backwards. I was not expecting Mia sitting on my bed with her high heeled foot pointing at me.

"Let me take them off!"

I smirk, happy to see my leverage confirmed. "Not now! I'm more interested to find out about your new punishment! Seems like you were being pretty obedient earlier?"

"You are an asshole Lina. I have to do everything mom and dad says and it's exhausting."

I pause to reflect on that for a minute.

She gets angrier, "now let me take these off or I'll call mom and she'll see you in your 'slutty' top just like she saw my makeup."

"You wouldn't."

She looks down from my eyes to my nipples, which is unnerving. "You must have had a tricky day today if you ended up wearing that top." She smirks, clearly with an idea in mind, "what did you see?"

I can't help but think back to one of my fellow student's awful essays before I can stop myself. My nipples harden again and the caressing intensifies. "Mia ... don't make me think about it - it makes it worse."

"Oh, does it?" She asks, walking towards me, menacingly.

I fan my chest in a futile attempt to cool it down and pull the top of it down to show more cleavage, making the caressing abate slightly. She's found an advantage over me, I worry.

"And so how does this make you feel?" She shows me the picture of herself from the party.

"Do you want me to remind you about this tomorrow, while everyone's around?"

For probably the fifth time this week, I find myself struggling to stand or keep my eyes open. I look up at my sister towering above me in my shoes. "Okay, fine, you can take them off!"

Holding the door frame, she kicks one foot up and gestures for me to take them off. I grit my teeth and oblige, knowing it's the only way to get some peace tonight.

She tries to do the same with her other foot but seemed to have some trouble keeping her bare foot flat on the floor. She takes the shoe off herself and rubs her feet. "Damn it, you've made me walk around in these damn things all week and now they cramp up when I try to put my feet down." She makes her way back to my bed on her toes, her ankle still at least an inch above the floor.

She looks at me, still at the doorway, struggling with the sensations from wearing a top I was no longer allowed to wear.

I check the app and see that I'm up to 71%. "Well, can you leave now?"

"How are you feeling? It looks like it feels good there!"

"It doesn't feel good, it feels dirty. I need you to go so I can take this top off."

"You want me to go, you want me to stop talking about how much I drank last Thursday..."

I am struggling to breath as the sensations are overwhelming. "Stop!"

"You want me to stop talking about which boy's lap I sat on?"

"No!" I tear my top off, unable to take it any more.

She looks at my curvy body, smirks proudly, and walks out of my room, dropping my shoes on the floor over her shoulder.

I think about how glad I am that she did this before midnight and not after as I lie on my bed with the air conditioning focused on me, trying to slowly undo my arousal by thinking about studying. The throbbing reluctantly reduces down over the course of a tortuous hour.

Note to self - don't let myself get above 80%.
