Rebekah’s hand was warm — Rebekah’s hand was always warm. It smelled like rosemary and gunpowder and Morgan didn’t mind, because she was busy trying to not come in such an embarrassingly short time. Rebekah knew exactly how to fuck her so Morgan turned into a pathetic moaning mess.
And to think most of the villagers thought Rebekah was still a kid because she was the younger sibling.
What would they say seeing this? Morgan had been easily manhandled to the backalley of Creek’s pub by a malicious and horny Rebekah. She still wasn’t used to the fact that her little sister was now taller and broader than her, not that Rebekah needed the physical advantage to be the one doing all the work.
Morgan wasn’t going to complain.
What she did was take it. Spread her legs as much as her trousers allowed her to, keep whimpering and moaning against Rebekah’s hands as the girl fucked her with three long and dexterous fingers.
“You’re way too noisy,” as if Rebekah didn’t know, at least, five different silencing spells. “Mother is in a meeting with old man Jay, she wants him to gimme a job at the pub. I won’t complain.”
Morgan knew Rebekah didn’t like anything that isn’t practicing magic and spending quality bonding time with her. But she also knows Rebekah is a romantic at heart, therefore wanted to buy gifts for her sister/girlfriend. It was adorable. And not distracting enough.
“Shh,” the hand against her mouth pressed harder and the hairs on the back of Morgan’s neck stood, she felt the lightest spark and saw the brief glimpse of gold on Rebekah’s black eyes. “Don’t let mom hear, you know she’s jealous.”
There was that — their bonding preferences bad to come from somewhere.
Morgan half wanted to be defiant, what was mother going to do? Probably watch it and pretend she was disgusted. However cumming was much more important than defiance that would satisfy Morgan for ten seconds of not less. Rebekah’s palm was pressing against her clit with the exact amount of pressure that made her feel too far and too close from the needed release.
Rebekah had barely touched her and she knew she looked debauched.
She felt dirty and needy, only Rebekah could that — only Rebekah was allowed to.
“Come on, baby girl,” she growled, putting more force behind her thrusts. “ Cum for me, quietly. I promise I’ll reward you.”
It was enough. Rebekah’s tunic was sleeveless and Morgan dragged her nails down her sister’s muscular arms. She hoped the hand on her face was enough to swallow her loudly moaning the name she shouldn’t be moaned as she came.
