To be a cuckquean

Emily stayed seated and Sarah's grin grew wide. "Good slut." Sarah said before kissing Alex's neck eliciting excited mews. "Lets show her how to make you moan." Sarah's voice was only just loud enough for Emily to hear. It was followed by Alex letting out a gasp and arching her back to push her chest further into Sarah's hand.

Sarah walked back with Alex until they reached the bed. Sarah sat without letting go of Alex's body. "Lift your ass up cutie." Sarah went back to speaking loud enough for Emily to hear. Alex stood on her toe and Emily saw Sarah's arms tighten as she lifted the smaller girl up slightly.

With Alex submitting to Sarah's manhandling Emily got to see how it looked when it was her throwing her little sis around. Sarah's knees appeared from below Alex skirt as Alex's legs were spread. "Sit down cutie." Sarah let down Alex and Alex did as she was told, sitting on Sarah's lap. Once she was down Sarah spread her own legs forcing Alex's even wider.

Alex's skirt was only just concealing her panties and with her top pulled down to expose her chest, her head leaning back on Sarah's shoulder as she moaned, and Sarah's look of pleasure. Emily was feeling less cuckqueaned and more like she was getting to watch live porn, it was resulting in a tent forming in her sundress, she wasn't sure how Sarah would react to such a tent so she folded her legs to try and conceal it.

"Looks like Emily likes watching." Sarah's statement made Alex's head pull forwards to look into Emily's eyes, it then followed by those eyes darting down to try and see her big sisters cock.

"Yes." If it was agreement or pleasure that pulled the words from Alex's mouth seeing how much pleasure Sarah getting from Alex made Emily feel kinda bad about their previous fucking. It had kinda always been more about Emily getting off than mutual.

"Good cutie." Sarah rewarded Alex with more neck kissing.

The sounds coming from pair was making the forming tent in Emily's sundress firmer. She wanted to touch herself so badly but didn't want to risk interrupting the scene before her.

As Sarah continued toying with Alex the hand that had been playing with her chest moved away. "I have waited soooo long to see this." Sarah's voice was dripping with pleasure and Emily looked at her face. She was staring at Emily clearly wanting to watch her reaction to something.

Emily couldn't drop the stare and from the edges of her focus she saw Sarah's hand move from Alex's chest, the finger tips tracing Alex's skin down her stomach and making small circles at the top of her skirt.

"Do you want to see?" Sarah asked as her other hand kept toying with Alex's ass making the girl's hips start to thrust back and forth in time with what Emily assumed was her anal fingering.

Emily nodded slightly as her hand tried to move to her cock without her brains permission.

"Say it. Say you want me to show you Alex's panties." Sarah's and gripped the hem of her skirt and lifted slightly.

"Show my Alex's panties." Emily mumbled softly.

"Louder." Sarah's hand lifted ever so slightly almost showing her panties.

"Please show me my little sisters panties." Emily said it before she knew what she had said, once it was out she tried to think of some way to take it back. But Sarah paid it no mind at all, hopefully she assumed it was just a kinky thing and not an incestuous thing, or she was into it which made Emily's cock drip out some pre slightly dampening the tip of her tent.

Sarah eyes left Emily and moved to looked down at Alex's crotch. The hand suddenly pulled upwards flipping the skirt. With Alex's pink silk panties finally exposed Emily felt her cock pump out even more pre drenching the her tent far too much for anyone to ignore.

"Wait I thought..." Sarah looked both disappointed and confused. Emily figured something out as a result. The marker made Alex a girl but that doesn't mean everyone would know she was a girl, apparently since Sarah figured she was a boy dressed as a girl, that belief didn't change as a result of the marker. Emily figured that this wasn't likely to come up again unless Alex was cross-dressing before uni but it was good to see at least one kinda sorta constraint of the marker.

Emily's internal noting had made her miss Sarah's fingers play over Alex's panty clad pussy seeking a cocklet. "I really wanted a sissy to play with. Oh well." She moved her fingers back from seeking and to pleasuring. "I love you panties." Her fingers found Alex's clit with expert speed and began to make quick small circles. Alex was losing her mind, the combined butt and clit **** was overwhelming her. Emily may need to tweak Alex's pleasure response after this, or it was just that Sarah really knew a woman's body.

"More, please more. Almost there." Alex mumbled out. Emily almost lost the fight with with her cock hearing that, it took a lot of her will power to stop her hands, in the meantime her legs decided to uncross themselves leaving the huge damp tent to stand there.

"Good girl." Sarah went back to planting kisses on Alex's neck as her fingers worked her clit and ass. "I bet you don't make these noises with Emily. Do you?" Her voice had taken on a sweet tone and Emily's cock pulsed hearing it.

"Y-yes. I love my big sister." Alex moaned out as her hips gyrated against Sarah's fingers. Emily felt a warmth in her chest knowing her little sis did actually feel this good during their fucking, though she had no illusions it was because of the marker increasing her pleasure more than anything Emily actually did.

"Does she make you feel like this?" The fingering increased in speed and tempo and Alex started to cum. Emily could stop herself anymore and flipped up her skirt exposing her cock. She wrapped a hand around it and started to stoke it as fast as she could, needing to cum with her little sis

"N-nooooo!" Alex screamed out as she came tensing her body against Sarah. Emily had been staring at that body the whole time as Alex came Emily moved her eyes to look Alex's face. When she did she saw Sarah staring at her, a look of utter and complete control written on her face.

"You are just so sensitive." Sarah cooed as Alex calmed down hers not straying from Emily's. "What do you think of that big..." Sarah's pride in her actions were clear and as she said big, Emily knew she had in fact taken the 'sister' comments as incestuous. What stopped her finishing the sentence was her, as her eyes moved down to see how turned on Emily was after being cucked, she saw Emily jerking off and just about to cum.
