As it's been a while since I've submitted anything, you might want to re-read the preceding chapters to get a handle on the story!
I've changed the category to sci-fi/fantasy as that seems to fit better as the story goes on.

Janine closed the book she had been reading and looked at herself in the dressing table mirror. Despite all that she had learned of the Ctholoids and the world they came from she was still a little nervous about her plan. If it didn't work then everything she had done, and everything she had made her brother Frank do, would be for nothing. True, the changes that had happened to her body would remain which, if nothing else, would be worth the risk, but she wanted so much more. Frank, she knew, would be happy to live out his days fucking the six girls that lived at the Chambers Academy for Wayward Young Women, but that wasn't enough for her.
There was literally another world out there and she wanted it.
A knock at the door brought her out of her reverie.
"Come in."
In the mirror, she saw the door open and one of the school girls, Kelly, stepped in. Dressed in the school uniform of short pleased skirt, ankle socks and blouse, she looked exactly like the slut she was. Her blouse was buttoned up but only just, the sides pulling apart, leaving large gaps between the buttons. With no bra beneath it, Kelly's huge tits were brazenly on display, her cleavage visible even if the top three buttons hadn't been left undone. Janine licked her lips as she looked at the girl, her favourite of the students, remembering the previous night when Kelly had shared her bed. She had spent hours fucking the wonderfully submissive girl, using each of her holes with the several large dildos she had.
"Everything is ready, Miss Chambers." Kelly said.
Janine stood, her voluptuous form covered by a simple bathrobe, the top revealing just a hint of the deep cleavage that formed between her big tits.
"Excellent. And are you ready, my dear?" she asked, stepping over to her. "Ready to begin a new life with me?" Janine reached out and cupped one of Kelly's tits, kneading it roughly, feeling her nipple harden at her touch.
Kelly gasped and arched her back, pushing her tits closer to her teacher, letting her have as much of her body as she wanted.
"Yes, Miss Chambers, I'm ready." she sighed.
"Excellent." Janine said again, using her other hand to take hold of the girl's long black hair and pull her head back. She dipped her head and kissed her roughly, the girl's tongue eagerly tangling with her own. She broke the kiss and looked at her. "Move your ass, girl. I don't want to be late."
Janine spun her round and pushed her out the door, Kelly stumbling in her high heels before she regained her footing. As the girl walked down the corridor, Janine watched her ass wiggling, thinking again of the previous night.
They walked to the stairs at the end of the corridor and went down to the single classroom where Janine had taught the girls. Any normal lessons had long departed and over the last couple of months, she had made the girls act out her own particular fantasies. As the effects of the Ctholoid cum had taken hold, the girls had eagerly embraced her wishes. The girls had taken it in turns to act as the teachers or even mothers of unruly pupils, punishing them at Janine's urging. Time and again the girls had been bound by ropes as their "teachers" and "mothers" had fucked them with huge fake cocks as Janine had watched.
As they entered the classroom, Janine was happy to see those ropes had been put to good use once more.
Her brother, Frank, sat naked, tied to a chair. Around him, the other five students stood in various states of undress, kissing, fingering and playing with each other. Despite the ropes, Frank didn't look unhappy; his impressive cock was at full mast and glistened with a mixture of spit and pussy juice. When he saw Janine walk in, his dick lurched and he grinned.
"Janine." he said. "Have you come to join in?" In all the months they had been together, she still hadn't let him get his dick inside her and he wondered if this game the girls had played was to get him ready for his sister.
"You'd like that, wouldn't you, Frank?" Janine asked. She undid her robe and opened it, revealing her gorgeous body to his gaze. "You'd like nothing more than for me to spread my legs and slide my pussy down that big cock of yours, wouldn't you?"
"God yes!" he gasped. The girls around him all laughed gently at the desperation in his voice.
"Or maybe let you ease that tool of yours up my ass? Would you like to do that, Frank, to ream out my butthole?"
"Oh fuck yes, please Janine. Can I?" Frank begged, again making the girls laugh.
Janine smiled at him and closed her robe again.
"No, I'm afraid not, Frank. I have something different planned for you but I think you might like it." She turned to the girls. "Ladies, if you would bring Mr Chambers along with you."
Janine and Kelly left the room as the five semi naked school girls managed to lift and drag Frank, still tied to the chair, after them. They headed out of the building, into the grounds at the back, the cold winter air making all of them shiver. Before he realised, Frank was dragged into the centre of a circle that had been painted on to the floor with sigils and symbols around it.
"Janine? What's going on?" he asked, a hint of panic in his voice.
"I'm leaving you, dear brother." she said. "You can have the school and the other girls but I'm going and taking Kelly with me."
"Leaving? Where to?"
