With disinterest

Sarah's expression was not one of shock or disgust, just simple disinterest. Emily wasn't entirely sure how to take that. Sarah was obviously interested when she thought Alex had a cocklet so why wasn't she interested in Emily's.

"You've both been good girls so far," Sarah lifted Alex off her and put her down on the bed, Alex was still kinda out of it from cumming. "Now I think it's time for the lesson to start." Sarah's face looked almost as tuned on as Emily felt. She was almost ready to cum when Sarah saw her cock which stopped the jerking forcing her to edge herself.

Sarah didn't say anything else she just stared at Emily expectantly. Under the commanding gaze Emily's hand returned to her cock and started to stroke. Sarah walked over and reach out a hand, Emily closed her eyes expecting that hand to land on her cock. She was surprised when the hand ended up on her chin and pulled. Emily opened her eyes and to see Sarah staring down at her. "Jerk off all you want, but if you cum without my permission you're out and Alex becomes my little sister."

The second part of that threat wasn't much a threat considering Emily's hold over Alex, but the first but sounded real enough. Plus this was the first time Emily had any actual constraint on her near bottomless libido, she was surprised by how much it turned her on.

Sarah seemed to see acceptance on Emily's face and turned her attention back to Alex. She strutted over and, making sure Emily could see, reached down and cupped Alex's cheek. "Are you ready for the next bit cutie?" The sweetness in her voice once again made Emily feel a little bad for how she had treated Alex's butt, she decided to take the tender approach when taking her little sisters virginity, at least she would try.

Alex mumbled something inaudible.

"Ah ah cutie make sure you sister can hear you." Sarah chided while staring at Emily.

"Yeesss more please." Alex's voice left no doubt that she was still on an orgasmic high.

"That's my good cutie." Sarah patted Alex before leaving the bed and walking over to a trunk. She bent at the waist to reach inside it giving Emily a perfect view of her incredibly well toned ass. Emily let out an involuntarily groan and stroked a little harder, what she would do to get a piece of that. "Careful, remember what happens if you cum without permission." Sarah was looking at Emily though her open legs and grinning, she knew the effect her ass had on cocks apparently. "Here she is." Sarah sounded positively gleeful as she took something out of the trunk.

She kept the item behind her back as she returned to the bed, keeping her eyes off Emily as she moved. Once she reached the bed she draped herself onto it, cuddling up to Alex lovingly. "Mmmmm." Alex moan in content pleasure at the closeness. Emily wasn't as turned on by the fact Alex was a bit of cuddle slut. Sarah grabbed a pillow and lifted Alex's upper body before setting her down on it, giving Emily an unobstructed view of her entire body.

"Open your mouth." Sarah's eyes were back on Emily and she moved the hidden item from behind her slowly. Before Emily could get a good look at it Sarah whipped it around and pressed it against Alex's lips. Holding it there Emily could see it was a dildo, but not like any she and Alex had bought, this was covered in small nodules, Emily felt her pussy clench slight as her imagination started to fuck her with it.

Alex reacted the same way she always did when presented with anything phallic shaped. She opened her mouth wide and took it as deep as could. "Wow," Sarah breathed out as Alex's cockslutery went on full display. Sarah looked over to Emily and her cock. "Trained your little sis well?" If Emily wasn't mistaken Sarah sounded impressed by this.

"Yesh, big sish cock." Alex mumbled out as she took the dildo down her throat. Sarah grinned and started to fuck her with it, slowly at first, trying to gauge how much Alex could take, when it became clear that this just wasn't as big as Emily, Sarah changed tactics.

"Hold it there for me." She pushed the cock all the way inside Alex's throat, out a hand on the base and held it there, her other hand moved between Alex's legs and started to press against her pussy. "Good girl." Sarah cooed as she massaged and teased. "How long does you big sister hold her cock down your throat?"

"Hmmmm ghak hhaa." Alex tried to respond with a cock most of the way down her throat it wasn't really possible.

"Really." Sarah responded as if that made sense. "You'll hold it longer for me won't you?" Sarah's fingers on Alex's pussy increased their tempo.

"Hesshh." Alex moaned out as her hips started to lift into the fingering.

Emily's hand had increased its tempo along with Sarah's. Watching porn in real life was fucking amazing, the fact that it was her little sis that was being the subby fuck toy made it soooo much hotter.

As Emily jerked off Alex began to make chocking noises. Emily had never stuffed her cock down her little sisters throat for this long before but Alex seemed to be taking it.

"You sure are a good little sis for me. Do you want more?"

"Hesshh." Alex groaned.

Sarah laughed and patted Alex's panty clad pussy eliciting an happy gasp. The hand that had been holding the dildo down Alex's throat withdrew it slowly. Alex coughed as it came out, but it was mixed with moaning. With the now spit drenched dildo free of Alex's hungry mouth Sarah used it to draw a line. Starting on Alex's chin she move down her neck and along her collar bone. "Where do you want this cutie?" Sarah asked as she moved the dildo lower to circle Alex's nipple.

"My butt, big sis, fuck my butt." Alex was clearly well and truly out of it. Emily let out a groan of pleasure as her cock pulsed, the memories of Alex begging for a reaming and the pleasure of actually doing it was making it hard for Emily to stop herself from cumming.

"You almost as slutty as the girls already in the sorority." Sarah laughed as the dildo lowered down Alex's stomach. When she reached Alex's panties Sarah pressed the edge against her and thrust it up and down slowly.

Alex threw her head back. "Oh God Fuck my ASS Please!"

The dildo kept moving up and down along Alex's silk clad slit the nodules along it's length causing constant new sensations of pleasure. "Are you sure you don't want it here?" Sarah's question was punctuated by the dildo moving to press directly against Alex's hole, making slight movements back and forth Alex was clearly struggling to think, much less answer.

Sarah looked at Emily to see her reaction. Emily was tensing the hand on her cock frozen. Alex's virginity was hers if Sarah moved to take it Emily would have to get involved and use the marker.
