After paying 500 dollars for 1 day in the hotel's private room, we went to the room.

"What are we going to do now? is there a ritual or magic or do we start directly?" I said with curiously.

"Yes, now I'm going to create a magic circle." She said with a red face.

'I still don't know why her face is so red. The way I see it, his face was red before I took those guys down. I will learn it soon.'

"SWOOSH"

'While I thinking she already finished the circle.' And a system message appeared in front of me.

=================================

{Warning: A master-servant circle has been detected}

{Circle's owner: Cynthia Rudowell (High-Succubus)}

=================================

"Now is there rule's or something" I said

"There is only one rule, you have to make me obey to you." Cynthia said while still red face.

=================================

{Rules has been determined challenge is started}

=================================

'When I saw the system message that appeared, I immediately went in front of her and started kissing.'

"mmf" She started moan.

"huf-huf. It felt really good, keep going" She said with breathless

" Hoo~ What should I keep doing" I said with evil smile.

"You're so mean~ K-kiss me more." Cynthia said while blushing.

I took off her clothes in one go. And I keep kissing her. I am touching her breasts and they are so soft. I touched her clitoris she moaned much and her eyes looking so beautiful. After all these moans, her ability to stealth turned off and her horns, tail and wings appeared.

I touched his horns and his moans increased. I even noticed that the underside is wet. It's almost like she's giving herself up completely to me. But I still kept touching her's wings and tail. She is making such a cute and lewd face now.

"Jake p-please" She said while almost climax

"What Jake don't you need to add something? Please what? What do you want me to do?" I said while still touching her.

"M-master Jake p-please f-fuck meeeee!!!" She did cum so much.

I did take her to bed and my cock almost inside of her.

"Do you want me to fuck you?" I said and looked at her

"Yes! Master please do! Please fuck me!"She is looking at me with those beautiful and charming purple eyes and red hair.

"Okay then here I go!"I said and my cock went in.

"Hyaaa~! It went in. It's so big please be gentle!" She shouted.

Their moans increased as I kept going in and out. I can't say I'm very kind, but it wasn't my fault that it was so good on the inside, what could I have done. I kept moving inside and she is a virgin, isn't she a succubus why she is virgin whatever I will learn later now I should keep moving.

"I am cummmmmiiiinggg!" She shouted and she cumed so much.

But I didn't cum so I will keep doing it. And I continued.

"Huh!? I cumed a lot but you still fucking me?!" She is shocked.

"Yeah but I didn't cum so we will continue until I satisfied" I said and looked her and still fucking her.

Hmm I think I will cum now

"P-please kiss me" She said suddenly.

"Who, who should kiss you" I asked her.

"Master Jake please kiss me!" She shouted but her eyes almost cry.

Then I kissed her. She was still moaning but kept going kissed her and at the same time fucking her. And a system message appeared

================================

{Now you are cumming do you want to give soul point}

{Yes}  {No}

================================

"I am cumming!"I said

"Me too master!" Cynthia said too

After that much cum I looked Cynthia but she fell asleep.

"Hmm so you've lasted this long. I said and a system message appeared.

==============================

{You give soul point now your evolving is starting}

{Warning: It will hurt like hell}

==============================

Then I run to the room's middle.

And evolve started, at the beginning there wasn't pain just a black smoke but after then that that black smoke turned on my everywhere and It started to hurt as if it was breaking all my bones one by one and rebuilding them. I still resist on pain. After a few minute pain is gone but black smoke still here. And I heard someone's voice.

"Stupid! Inhale the black smoke in the air through the skin, through your mouth and nose."A man's voice came out.

"Hey why are you calling me stupid and who are you." I said with anger

"Don't answer me just do it, I will explain everything to you after this"That man's voice said

"Okay" I said and take all the black smoke in air to me. But it still hearts.

"Now use that smoke and you must pass it through your muscles and flesh as if it were an intravenous line to your own body."Than voice said

I did it but pain is so much a lot of system message appeared but I couldn't look at them after I finished all of a sudden I was tired and I passed out.
