Sarah was kind to Elena

You woke up, alone. You got up, then headed to Elena's room, where Sarah was laying next to her. You smiled, seeing Sarah be nicer to Elena. Elena's attitude towards her, made you convince that Sarah was nothing but cruel.

"It has always been me." Sarah said, moving to you, Elena still asleep. She kissed you softly "She needed someone with her, to comfort her. She wasn't use to being DP'd like that." she kissed you again "She did play with her pussy once."

"Can't punish her if it was a wet dream." you said, looking at your naked, sleeping, sister. She was really worn out. She always woke up before you did.

"Lucky for her." Sarah commented, moving closer to you, causing you to back out of the room. She closed the door and led the way down to the kitchen "I don't want to wake her, so you'll have to be my breakfast." she turned and her fangs were flashed. You waited for this. You wanted to know what it was like. Sarah took you to a chair and sat you down "You're the Domme, so I'll be softer. Even make you cum. Elena gets denied unless she was good and never gets to sit down." she moved around, so she was behind you, tipped your head to the side, bit your neck, while she rubbed your pussy. She fingered you softly, while finishing her feeding.

You moaned as she held you still with her other hand, keeping you from shaking as the orgasm destroyed you. Next thing you were aware of, was Sarah sitting across from you, a plate of pancakes, banana, and the syrup bottle. Elena had just entered the room "Feed off of her?" Elena asked, noticing your state.

"You know that orgasm I gave you the first time." Sarah said "Her being the Domme, I am pretty sure I am in for some retaliation."

"You are a vampire and can handle it." you said, finally fully aware "Fucking shit...that was strong."

"See why we need two humans when I turn you?" she said "Those orgasms are way too powerful and pretty much mandatory when feeding. Vampires are immune to it, so it'd be more like sex."

"When will we do this?"

"Well, Emma, I want you to feel as many feedings as I can give you until we just give up and I turn you. Elena, you get a week or two off." Sarah said, watching you eat. Elena just started eating.
