Without a second thought

You watched as Emma leaned in just as you had done moments ago, with there being no hesitation from your sister once again and the kiss between them lasting just as long as the one you had just shared before they moved apart.

Sarah was still facing away from you and towards Emma but you could see Emma smiling and looking into her eyes, a smile that you knew was definitely being returned in kind. There was no hint of jealousy as you watched the two, only a feeling of wanting to go further with them as your cock started to react to the both of them making out.

You actually felt glad that the two of them could share a spark that you also had with Emma as it meant the idea of the three of you living together further down the line would be a lot more comfortable, especially if you could all share the same bed at night.

You made a signal to Emma and started to reposition yourself, finally getting to see Sarah's face as she looked in your direction to see what you were doing. The blush had remained on her face and her lips had naturally curled up into a smile that didn’t seem to want to leave, Sarah probably not even knowing that you could see her every expression so clearly on her face.

The three of you started to move as you went away from the edge of Emma’s bed, with you sat up leaning against the headboard while you directed Sarah to sit between your legs, slightly leaning to one side so you could still comfortably see her face and you gave her a light kiss before you shuffled to get comfortable.

You were sure she could feel your erection pressing against her ass as you moved, even through all the layers of clothes but Sarah's attention immediately switched to Emma as she crawled up the bed towards both of you. You rested your hand on Sarah's stomach and let your finger go under her top, running them tenderly over her skin as you felt her pulse start to raise.

Emma did her best to put on a show as she got ever closer to the two of you, stopping with a leg on either side of Sarah and sitting down on her thighs. She gave you a wink when Sarah was too busy looking her over but you were almost just as entranced as she was, your eyes widening as Emma raised her arms to take off her top, throwing it to one side once she got it off which left her sitting there in just a bra and skirt.

She could see the entranced look on your face and you assumed the same look from Sarah was what made her grin as she watched your reactions, bringing her face closer to Sarah’s.

“See anything you like?” she teased, lightly kissing Sarah before she pulled her lips away.

“O-Of course I do. You look amazing” Sarah nervously replied.

You had to admit, the more dominant version of Emma was fun for you to watch and while you were slowly trying to inch your fingers further up towards Sarah’s chest, you were enjoying the show with front row seats. Emma had never really said she was on the submissive side when you had had conversations in the past but she had certainly enjoyed hearing about the other subjects showing the tendencies when you described them to her.

She had never really been dominant either when it was just the two of you and you’d say she was the subject you felt you had the most back and forth with. Now though, she looked to be enjoying playing with Sarah and while part of you wondered if it was her sadistic side still lingering around even after you got rid of her kink, you saw that she had no intentions of directing it towards anyone but your other subjects.

“I think she deserves a better look don’t you?” Emma asked, looking at you as she slowly started getting Sarah worked up.

“I don’t think you have to be the only one revealing yourself though right? That hardly sounds fair” you replied, Emma’s eyes twinkling as the two of you got on the same page.

You made it clear what you were getting at when you moved your hands back down from where they rested and ran your fingers over the hem of her tshirt.

“It feels like you guys are teaming up on me now” Sarah responded, still moving to remove her top even if she had figured out your intentions.

As the top obscured Sarah’s vision while she pulled it over her head, Emma nodded her head in your direction and urged you to join the two of them in removing an item of clothing, something you didn’t need much convincing to join in on. You threw yours to the side just as Sarah’s leaned back against you and noticed you were now making skin-to-skin contact, about to make a comment on it when Emma took hold of Sarah’s chin between her fingers and locked eyes with her.

“Are you saying you don’t want us to team up on you? I’m sure we can find all sorts of ways to make it entertaining for you” Emma teased, slowly moving her hand back until just the tip of her index finger was keeping Sarah’s chin raised.

“Well I…I mean…” Sarah murmured, stuck between you and Emma with nobody there to help her get out of the situation she had brought on herself.

Still, you did feel the need to give her some sort of reward for at least taking off her top and while you were sure Emma would continue teasing your sister until she was left a nervous wreck, you wanted to move on and get to what you considered the good part, with the two of them taking off more clothes and getting a lot closer with one another. Maybe when you had more time and could spend hours and hours with the two of them, then the idea of teasing Sarah until she couldn’t bare it any longer could be something you’d put more thought into.

“I’m sure she wants us both to use her however we please isn’t that right, dear little sister of mine?” you added, taking a firm hold of her waist and making sure she was now firmly put in her place, even lightly pushing your hips up into her to confirm you were hard and ready for her answer.

With Emma right in front of her and you making sure your presence was known behind her, you knew Sarah would have to make her desires known to get out of this situation. A reward only if she could work up the courage to be honest with both herself and the two of you.

“Sooo, what will it be?” Emma teased, giving her one final nudge to get her to respond.
