Katie, the Kitsune

John saw his old crush, Katie. She turned into a Nine-tailed Fox aka Kitsune. Her hair turned red matching with her tails and ears. She looks at you with her golden cat eyes. John smile at her, which make her blush.
"Can I sit here?" John ask.
"O-Of course. Here, sit here John." she stutter a little.
"Thanks." John said and sit there.
"So, John. Do you have a girlfriend yet?" Katie ask, while hardly blushing.
"No, not yet. I'm planing to have a harem, maybe you want me to take you?" John ask, while moving his hand to Katie's skirt.
"You want me?" she ask.
John move his lips closer to Katie's and kiss her on her lips.
"Sure." John say as he breaks the kiss.

'If a male take a girl, the male's mark appear on the girl, marking the girl as his. This mark is unbreakable by other males.' snap.

As John made this new change, his mark appeared on Karie's left arm.
"Welcome, Katie. You are mine." John said and moved in to kiss Katie again.
Katie didn't resist, she accept John's kiss happily. They kissing each other for a long time until they run out of oxygen. John then break the kiss.
"I can't wait to mark as many girl I can." John said.
"I will support you, John. As your girlfriend I can't deny such a perfect man to have a harem." she giggle, while you feel her tails waving happily. "Maybe, my BFF would like to meet with you."
"Annabel? Maybe." John said, he didn't know what creature Annabel turned into, she always was a little delinquent type.
"I know Wolfgirls can be sometimes aggressive, but she can be kind too." Katie answered. "Anyway, do you want to add to your harem Futas and Sissies?"
"Yes, of course. They all beautiful." John said. "Why? Do you hate the idea?"
"No, of course not. Just want to know if I should look for those type of girls." Katie smile.
"Don't worry. I will handle it." John said and kissed Katie again.

John and Katie talked a lot, until they arrived to their school.
Katie has the same classes as John, so they walked together to their class. When they arrived they were greeted by Samantha, or Samuel before he was turned into a Incubus Femboy. She is John's best friend and has a huge crush on him. Incubus Femboy is the Femboy version of the Incubus, the other version is the Incubus Futanari. The female version is the Succubus. Each of these type of Demons choose a male as her partners and stay with them forever. They feed on their sperm, and in return they extend the male's life.
"Hey, Johny boy." Samantha greet him. "How are you, beautiful?"
"I'm okay. How about you?" John ask Samantha.
"I was fine until I didn't saw you, now I'm wet." she said with a seducing voice.
"Well, Katie is my girlfriend now, if you want to join my harem ask her." John said while Katie hugged his arm.
Samantha looked at Katie with puppy eyes.
"Well, I'm okay with her joining your harem, but you don't need my permission. I will accept anyone until they don't want to steal you." Katie said.
"Yeah. She's right." Samantha said, while hugged John's other arm.
They stayed like this for a while, until they Homeroom teacher arrived and the class begin.
