The wide smile on Ginny's face was impossible to mistake as she charged into the boys' dorm room. Only now, did Ronni try to hide her new body, pulling a sheet up. Alas, most of the bedding was firmly tucked in, so she looked more like a tease, than a genuine attempt at modesty.
"Hi, Harry." she said in a joyous voice, ".... Hi, Ronni." she smirked to her new sister.
"So have you told Harry about your full punishment?"
Timidly, with a look of absolute terror on her face Ronni shook her head. Either telling her sister, she hadn't, or silently begging Ginny not to reveal it.
"WAaaahhh..." Ginny erupted in a convincing reproduction of a crying child. As Ronni was horror struck, in moments, the reason was clear, as two damp patched formed on Ronni's sheet. Their location leaving no-one in any doubt, that she was leaking....
"This is for taunting me..." Ginny said, with a snarl, that suggested a past incident, she hadn't forgotten, or forgiven.
"So do you want to go to the kitchen to be milked, or shall I summon the house elves here?"
She took a deep breath, as Ronni weighed up her options, clearly readying herself for another babyish outburst, and another humiliating leak for Ronni.
Harry gently put out a hand towards Ginny, as if gesturing for restraint.
"How long does this punishment last?" he asked uncertainly. Hoping that Ginny would be merciful, and consider the duration long enough.
Ginny herself, was turning crimson, her cheeks hot, as she'd just revealed herself as another victim of this punishment. Her eyes were low, unable to meet Harry, and darting towards her sister.
