You wondered what it'd be like to be dominated by Sarah. She helped Elena move onto the bed, where she rested, while watching Sarah pull you off the bed and sat on the edge. She took a handful of your hair and **** your face to her pussy. She ordered you again to lick her, which you did once, then stopped. You were in a playful mood "I really wouldn't tease her, sis. Sarah gets aggressive when she is horny, teasing her will make her even more rough on you." Elena warned and before you could try and heed the warning, Sarah tipped your head back "Should've said something sooner. Sorry!"

"I'll get a size of a strapon that fits my style and use it on your holes, Em. Lil Slut there told you I get aggressive and my size make that an understatement." she said, her eyes going dark red. You licked her feverishly, like you were starving for a week. You sucked her clit, almost tongue fucked her, and everything that would make Elena go crazy. Sarah moaned as she held your head there, keeping her grip tight.

You picked a 7' strapon with an average girth. If that wasn't her size, then what would her size be? The thought terrified you enough to obey. But you knew Sarah and she would get it anyways, just to use it. And it was early in the day. Even worse, because if Elena distracted you, then Sarah could get it. Maybe two. No, she would only get hers and Elena would use the one I got. you thought as Sarah tensed as she cums in your mouth.

She pulled your head away "Elena keep her on her knees. I need a dildo." she said, getting up and returning shortly after, then getting back in her position on the edge of the bed "Make me cum again and we'll let you have the day off, while we make the rules." she handed you the dildo, which you used hard and fast on her. She didn't take long, happy you made her cum quickly. She let you up as she went downstairs to make you both breakfast.

You saw a list on the fridge:

• Naked, all times. Lingerie is an exception.
• No orgasms without permission
• No masturbation without permission, only one is allowed per day, no matter what
• Free use by me and Elena
• If either of us are horny, make us cum

It was rules for you. You would've changed the No's to Yes's if it wasn't for the last one, which was most likely written by Elena:

Do NOT mess with this, or else, Em

You sighed and Elena walked in "Someone's still clothed. Unless you count underwear as lingerie." she commented, reading the rules "Can I punish her, Sarah?"

"As much as I want to see you strip your own sister, let her process the rules first." Sarah said "And we could consider that lingerie. For now."
