Her older sister

The woman who greeted you in the doorway looked like Emily, but different and slightly older. She wore nothing but a fuzzy red bathrobe tied loosely around her so that her top was all cleavage and her bottom half was barely covered.

“A boy?” She said, slightly surprised “what do you want?”

“Sorry to bother you Miss. Emily asked me to meet her here?” You say, putting as much deference as you can into your words.

“Ah, I see. Come right in, she’s just inside.”

Leading you into the dorm, you see that women’s rooms were much larger and nicer than the ones given to men. Queen sized beds, larger bathtubs, and even a small kitchen. It’s not until you get into her bedroom that you see why Emily herself didn’t answer the door: on her bed naked with her legs and hands bound above her head and a ball gag in her mouth was Emily. A vibrator in her pussy keeping her constantly stimulated.

“Hey Em, is this the boy you told me about? The one you said was ‘cute’?”

Emily blushed, not just from being exposed as she was but also from her older sister saying something that had apparently been told to her in confidence. Despite that, she nodded meekly.

“Em here is on disciplinary probation” her sister explained to you, as if discussing something as mundane as the weather “so I became responsible for her discipline. She’s on the level of a boy for the rest of the semester. And it’s only been like a week since it started.”

“What did she do?” You ask, curious about what she could have possibly done to warrant such a punishment.

“She talked back to her Intro to Dominance professor one too many times. It’s not completely her fault, the old woman who teaches the class is a notorious hardass, but it was still a dumb thing to do. Luckily she had me to take responsibility for her punishment and not some other senior.”

At the sight of Emily and the description of her predicament, you couldn’t help but become aroused, and after a day of teasing with no release it was almost painful.

“Oh!” Said the sister “Hey Em, looks like your crush likes you back! Want to help him out?”

Being gagged, she couldn’t respond with more than a moan, but her eyes remained fixed on your cock as her sister started slowly stroking it.
