Cheer for Cock

There were no guys in the Common Room right now. Was there something going on here? Hermione was... stretching. She didn't look like she wanted to be doing it, but it was like the Uniform was enchanted to make the wearer move. The other Witches were also moving into stretching exercises.

Was it just a coincidence? Lavender noticed Ginny, who was relaxing in one of the big armchairs with her legs wide open and jizz leaking out of her arse.

"They're waiting outside." She gasped out. "They are waiting for us all to come out and cheer them... cheer them on to a long day of... of fucking all us Free-Use Bitches."

Earlier

Apparently a whole night of sleep was enough to get Hermione approaching her personality before Prifessor Lockhart tinkered with her memory. She was loudly hating the new "Uniform", enough to wake Ginny.

Finding no boys, but signs they had passed by, the two moved to leave. Outside of the Common Room, the Gryffindor Boys were all stood waiting. One mentioned their friend hadn't come back yet from fucking Lavender.

When they saw Hermione and Ginny, one of the boys threw a pair of pom-poms at them. Ginny ducked, Hermione didn't.

"Why did you just wh-?" Whatever Granger wanted to do was interrupted by her body moving to Cheer. The pom-poms glowing lightly. Her movements centred around bouncing her tits and flashing her arse and cunt. She tried to rant, but stopped herself when she noticed expectant looks and a more intense glow from the obviously enchanted pom-poms. No. No she was not going to say something stupid.

Meanwhile, Ginny got to receive a brief summary of what was to come while getting her arse fucked.

Gryffindor Common Room

"So Hermione's not really stretching and preparing, she's being made to by the pom-poms. Pom-poms that can control our bodies and probably what we say?" Lavender asked Ginny, who nodded, looking a little more recovered now. "Well, looks like we're all here, let's get our boys hyped up and hard for us!" Lavender stated cheerfully, happy for more dicking. She'd already tested, and whatever the Nurse had done the day before was still affecting her. She couldn't masturbate. The only way she was cumming was by bouncing on Wizard dick.

Outside the Common Room, Lavender could feel the magic in the pom-poms she was thrown, and what felt like an invisible hand around her neck.

All the Gryffindor Girls hopped, bopped, bent down, raised a leg high, and exposed themselves to their Housemates. All while chanting in unison about being needy bitches **** for cock.

Quickly they were set upon. Lavender saw Hermione on all fours while Ron pounded into her, the boy holding Ginny's hair and pushing her behind him to eat his arse.

Lavender herself got grabbed by Harry. She was **** to balance on her hands while a still standing Harry raised her lower half and fucked her from behind. Then he began walking, pushing her forward like a wheelbarrow.

He didn't stop thrusting into her and sometimes he stopped to smack her arsecheeks. With her expanded chest, her nipples dragged on the floor, teasing her and making her moan. It took a while to reach the Great Hall, and by the time they had, Lavender had cum several times and Harry had pumped so many loads that she had a small cum belly.
