Luna has some fun

Ginny licked Luna's honey pot with more and more appetite, the taste and smell coming from it made her increasingly aroused with each passing minutes. Her own crotch was soaked wet and was aching for a big cock to fill her love cave. She wanted more, she needed more, to the point of forgetting where she was, and almost who she was.

Luna, then, grabbed Ginny and lifted her to put her on the table. She then spread the legs of the witch and she could see the blonde's clit grow into a five inches cock. Drowned in arousal, she didn't care and let her fuck her. It wasn't big, but she didn't care, it was scratching the itches enough. Luna, grabbed the book and put it next to her, she then opened it on a random page and read it out loud. Ginny still didn't care, she was about to come, she was so close.

But Luna came first, the sight of the changes to Ginny was too much to resist the orgasm, and she didn't want to. She pulled out, raising protest with the redhead.

"Don't stop ! I'm soo close !!"

"What are you doing here ? What's going on ??" a voice shouted.

It was one of the teachers, but Luna looked at him with a big smile.

"Well, I have the perfect thing to help you !"

One incantation later, and a pile of clothes was on the floor, in the middle a big purple dildo was erected.

"Y-You turned him into a dildo !" Ginny said in shock.

"I'll be more useful like this."

Luna grabbed the dildo, it was throbbing and a white liquid was oozing out of the tip. As she lend it to Ginny, she couldn't leave her eyes from it. She took it and started to masturbate with it, she needed to come, fast.

Luna left the poor Ginny in heat. The spell she used on her a second pair of breasts, smaller, under the originals. The four of them were linked by piercings with a chain and an inverted pentagram in the middle. She had heavy colorful make up and a fifth piercing on her clit. She was fucking the large dildo with passion despite it size.

Hermione was enjoying Lavender's sucking her teats. It was a pleasure similar to masturbation and all she could do was mooing like a dumb cow. Her roommate was enjoying the milk so much that she was drinking without rest. She could feel something changing in her as she was doing that, but she couldn't stop nonetheless.

"What the heck is happening here ??" Parvati's voice suddenly resonated in the room.

The third roommate had arrived and was in front of the weirdest thing she ever seen. Hermione changed into a... a cowgirl or something and Lavender sucking her tits while herself was changing too, somehow...
