I use magic and on Yukiko.

I made a stop in pharmacy on my way back and bought indigents for aphrodisiac. I in some of visions Kitami thought me how to make it.

I walk into home and go to my room. For next few hours I study the Bible Black. I found the spell that I will use on my sister.

At 8 o’clock I go to Yukiko’s room and knock.

“Sis, you’re there?” I wait a moment and enter. The air inside is heavy with sex. Yukiko is lying inside the bed covered by sheets. It looks like she spent, here entire day, cuffed, masturbating. “You alright sis?”

She moves a little.

“Y-Yeah… I just feel not to well right now.” She says nervously. She obviously doesn’t want me to find her in this situation.

“You’re ill? Should I call a doctor?” She twitches.

“No. I’ll be alright.”

“Ok. You know what, I will make you some soup for dinner.” I leave without waiting for her reply.

I go to kitchen and prepare dinner for my sister spiced with aphrodisiac. I return to her room, and place a soup on her desk.

“Your soup, Nee-san” I say and leave the room. With her hands still cuffed she will have to drink the soup with her tongue – like a dog… bitch would be more accurate word. Bitch in heat.

I get back to my room and start preparing to cast a spell. I write with my blood my and Yukiko’s names and surnames. Then I place Yukiko’s drenched underwear (I took the from the floor, when I left the room) on paper and start chanting a spell. It isn’t particularly strong spell. It makes person dream a wet dreams of someone. In that case, Yukiko will have wet dreams about me all night. Combined with aphrodisiac, it will give quite interesting effects.
