In the kitchen

You had dropped off the Tazapper and grabbed the collar. You heard footsteps in the hall, which you quickly caught up to "I'll give you another clit orgasm if you try to use that on me." you warned, watching your sister's ass she descends the stairs. She had a shirt that reached the top of her ass, but if she had smaller tits, it would probably cover half of her ass or all of it.

"I'm willing to submit. You don't need to tell me that. Besides, I am not stupid to try and use that on, if you have a chance of turning it on me." she said, entering the kitchen. She sat down, as you worked on lunch, which is breakfast for you both. You had the collar in your pocket on your robe. Underneath you only had your thong on, with no bra. For you, they get uncomfortable, given how big your tits are. Elena was the same, but she wears sports bras instead.

She didn't wear one right now, but you didn't care. Right now you are busy cooking, but you could see that she was torn about something "Sarah will be hiding. She is very good at it, so you'll need some help. I can only give you clues, but even that will get me in trouble with her." she said "Start with the Sanguine Rose on the other side of town. The place where it looks like it was straight from some vampire story." she gave a clue to help find Sarah.

You heard of Sanguine Rose, it was rumored to be a place for vampires and acts as a physical dating site, a night club, and a bar. "Fine. I'll go during the day, even tho I shouldn't take orders from a sub." you said. You both knew it is more of you treating her as the big sister, than taking an order.

Before you left, you pulled the collar out and placed it around her neck. She did not like that "Really?" she asked, but you were more occupied with the sight of your sister in a collar you bought from some sex shop. She was growling when you left.
