Some planning

As Emily dumped a fourth load into Alex's ass the images of a harem refused to leave her. As the faces of her past leaped into her mind painted with her cum fueled her thrusting she emptied a fifth load into Alex. Alex for her part was mostly ****, having pasted out after the third load at this point all she was aware of was the fucking getting slightly easier as cum lubed Emily's cock.

Emily pulled out of Alex and moved her cock to be cleaned by her little sister. At that point she realised Alex had passed out. With a dirt grin she pulled Alex's face off the mattress and rested Alex on her cheek. she pushed her cock against the **** girls lips which parted instinctively and allowed the cock to clean itself using her mouth.

Emily slowly stroked her cock with her head resting inside Alex mouth until she came one last time. She took her cock out and watched the cum drip from Alex's mouth. She looked at the mattress and used the marker to clean all the cum off it. She looked at Alex with her hips slightly raised her ass reddened with cum leaking down it and her red hair mattered to her face from sweat. The slight filled Emily with so much dominance she leaned down and kiss Alex's abused ass before writing 'CLEAN' on her left cheek. the cum and sweat vanished, though her hole didn't not return to its tight puckered self.

Emily walked to her laptop and checked the time. It was 3 am and she felt slightly tired reading that. She wondered if the marker could help with that. She was studying psychology, or was going to start in a day or so, and knew that sleep had a lot of parts involved. She figured she could check risk a day or two using the marker.

She put it to her wrist and wrote. 'AWAKE'. She felt as if she had gotten the best night sleep of her life. She wiped off the mark and everything went black.

She woke an hour later still sitting on her chair. "Ok so not doing that again." She figured that once she wrote that on her the mark became the literal embodiment of it. i.e. wipe off awake you fall asleep. She would have to be careful.

She looked over to the bed and saw Alex had moved onto her side, she was curling up slightly. Emily grinned seeing the desire to be spooned by her big sister in her little sister and climbed onto the bed wrapping Alex in a loving embrace.

They awoke to the sound of an alarm ringing. Emily groaned and turned it off before laying on her back. Her cock was rock hard. She had always wondered about morning wood. She heard stories about it feeling better to jerk it off than jerking off normally. She gave it an experimental tug and instantly agreed. Her hand began to jack hammer her cock seeking release when she heard Alex softly snore.

Alex was still sleeping. After the fucking Emily gave her body needed time to recover. Emily straddled Alex's waist her cock resting on Alex's stomach leaning a glistening of pre cum as it rubbed against the incredibly smooth skin. Emily reconsidered pushing inside any of her little sisters hole and instead began to dry hump Alex's stomach.

She was slow and careful to not wake up Alex. The growing trails of pre cum on Alex's stomach becoming harder and harder to call trails and not pools. Emily looked at her sweet little sisters face as one of her hands pushed her cock harder against Alex's stomach.

Using her **** body to jerk off was getting to Emily way more than the butt fucking she gave her last night. The sight of they red lips slightly parted, her eyes closed and her breathing unchanging gave such a thrill of control Emily was already getting close to cumming.

As she humped Alex's breathing sped up. Her body knowing it's place thanks to the mark was doing all it could to give her big sister an erotic display. Her cheeks flushed a red that spread down her neck and to her upper chest, her nipples hardened and her tongue darted out to moisten lips to prepare for whatever invade Emily wanted to give it.

Emily stopped humping in favour of just jerking off. Looking down at her little sister with her hand a blur on her cock she came. the first spurt landed on Alex's chest between her tits. The next hit her neck and chin. the next her face, a small amount hitting her lips and licked up instinctively. the final landed right before her cock and finished the look of the perfect cumshot.

Emily hopped off the still sleeping Alex. She figured that would wake her up. "Oh well." she left Alex with the cum on her and went to get some food. She had plans to make, plans that almost solely revolved around getting more holes for her to fuck.

She was sitting on the couch with her phone in her hand looking over some of the profiles of people she just met. When Alex finally joined her. She was butt naked and bounced into the room with now dried cum still on her chest. "Hey sis. Whatca doin'?"

"Looking to make a harem." Emily answered honestly as Alex joined her on the couch.

"Really?" Alex looked at Emily's phone and the pics of some girls. Her hand then moved to Emily's thigh and nudged her soft cock.

Emily felt her cock had gotten more than enough attention so she grabbed Alex's hand and moved it lower. She kept looking through the profiles as Alex worked her clit. "Who was the girl that ate out Sarah the other night?"

Alex's face lit up with red and her legs started rubbing together. Either the memory of being used publicly got her really going or she really wanted to see that girl riding Emily's cock.

"Ellette." Alex took Emily's phone to find Ellette's profile. When she did her strumming on Emily's clit sped up. There was a picture of the mousy girl looking down reading a book that had clearly been taken by someone else. Emily didn't find it particularly sexy but her little sister way sitting naked right next to her and jilling her off.

"Do you want me to add her to my harem. Get you a cute little play mate?" Emily whispered in Alex's ear as her hand moved between Alex's thighs. She was drenched and Emily wasted no time in playing with her.

"Y-yes. I want to play with her." Alex moaned as her fingers sped up once more. "Can we both play with your cock big sis. I promise to share."

"Oh god yes." Alex's fingers were magic as they pushed inside Emily. "Fuck I want to watch you eating each other out." Image of her little sis and Ellette trying to make the other cum flooding her mind.

"mmmmm we'll do anything my big sis want, we'll eat each other out for hours, we'll be on our knees begging for your cock. on all fours waving our butts at you begging for a fuck." Alex's whisphered words got to Emily quick enough and she came. Her cock even spurted some seman onto her stomach.

The sight of her big sister cumming pushed Alex over the edge as well.

When they came down Emily kissed Alex deeply. "You know how to contact her?"
