I mean really what do you think he is going to do

Alex smiled a little and bounced a little harder. He pushed out what he hoped would be a submissive, girly moan as he looked down from her eyes. "M-maybe we could try, like last night." He stopped moving with the dildo all the way inside him and looked at her hopefully.

Her smile suddenly became more predatory and she stopped playing with herself crossing her legs and straighten her back further until she looked in charge. Alex let out another girly moan, this time an all natural one as he went back to bouncing.

"Good ****." Another moan escaped his lips. "In that case there are a some new rules for you. One from now you'll wear whatever I want you to wear, we'll go shopping after this for some clothes that fit that flat chest and bubble butt." Alex felt his cock pump out some pre as she gave his new rule of life. "Two, you'll do whatever I say whenever I say, no matter what." Alex's moaning had stopped pausing and was now a constant stream of slutty gasps. "Three, you'll do all the house work from now on since you're so good at it." There was real appreciation in her voice and Alex felt a swell of pride at satisfying her. "Four, from now on you'll be sleeping in my bed." She picked at his blankets with distaste and he felt a little shame at not being up to her standards "Five," she seemed to waver a little as she tired to think up number five. Alex was starting to lose his ability to pay attention as his orgasm was building. "Five is..." Alex's legs felt weak as he rode the dildo feeling himself starting to cum. "From now on... you'll only be my little sister and I'll be big sis." Alex could see her legs quiver a little as she said that.

Alex couldn't hold back anymore. "Oh Fuck yes, whatever you say big sis." Alex let out as he came, his cock being milked of his cum as the dildo ground against his prostate.

Emily let out a moan as he did that and she spread her legs. "Well come on give you big sis a kiss." Alex hopped off the dildo and walked over to her, his cock still hard. She looked at it and gave a cooing sounds. "It really is such a cute little cocklet my little sis has." Just like last night when she called him cute he felt a shiver of pleasure.

Alex got onto his knees and licked at big sis's pussy with all he was worth. He remembered all of her sweet spots form last night and without any **** clouding his mind he could devote even more of his attention and mind to making her pleasure enough to prove that he will be the best little sis ever.

"Oh God little sis you are so good at that." Emily's fingers ran through his hair and took hold guiding him to further her pleasure. "FUCK I LOVE YOU TONGUE." She groaned out as he upper body fell back and she just enjoyed his oral attentions.

Alex move his finger up to her pussy and stoked and teased whatever wasn't in his mouth. He move a finger inside her and thanking off his pornographic knowledge pushed downwards. Her body pulsed and he built up a rhythm. Her breath became rugged as her fingers dug into his scalp.

"OH GOD LITTLE SIS YOU'RE GOING TO MAKE ME CUM!" Her legs tightened around his head and she pulled his tightly against herself. He couldn't even manage to move his fingers inside her as her pussy tightened up. "FUCK!!" Her body shook and he felt himself begin to run out of air. It didn't really matter to him, so long as his big sis was happy.

That sentiment began to waver as his need for oxygen overtook his need to please. Her legs relaxed suddenly though her fingers still kept a tight hold. "Wow little sis you really know how to make your older sis cum." She pulled him upwards and kissed him and once again just like last night licked her juices off his face.

She moved him down to rest against her side. He curled up against her as she wrapped an arm around him. "Alex, I think this is the beginning of a beautiful friendship." They both laughed as her arm around his side stroked him soothingly.

They stayed like that for a while enjoying the closeness until Alex could no longer hold it in. "S-so, big sis, about my new clothes." the thought was driving him crazy and it was impossible for Emily to ignore his cocklet rubbing against her side.

She sighed in an attempt at exasperating but her excitement at more dressing up was the same as his, only less physically obvious. "Ok then little sis, but you can't go out like that." She rubbing her waist against him and he let out a moan. "I'll go pick out your outfit you deal with that." She got up and had dashed out of them room before he really had a chance to do anything.

In a need to get off quickly Alex resorted to just jerking off. He barely had to touch himself before he was at the edge. When he came he picked up the marker and wrote 'SOFT' on himself once again to make sure this wouldn't be a problem anymore. He then, out of a need to further please Emily by playing the little sister role wrote 'GIRLY' on himself. He could feel the change happen in an instant. He grabbed a mirror and look at himself. There was barely any difference. He knew he was already girl but having the marker itself agree with this felt... amazing. He knew it was working on his desire but to already be so close to what he wanted made him horny again. Thankfully his cocklet didn't even question the mark and his ass received all of the horniness.

He looked at the dildo chair and felt an emptiness that needed filling but could hear Emily rushing around. He realised that Emily hadn't noticed that the chair and the dildo was one in the same. He quickly wiped off the 'DILDO' and hoped she would just assume he had an actual dildo, that he also now needed to buy.

"Alex." Emily's happy sing-song voice called him and he quickly moved to join her excited to see what she had ready for him.

When he walked he saw a set of clothes set out on the bed. He was a little disappointed they weren't as slutty as he wanted. There was a knee length skirt, a short sleeved blouse and pink panties.

He got dressed and felt his disappointment vanish. True the top wasn't slutty at all, but with his butt the skirt rode up and with each step would ride up a bit. He bounced around the room and figured out that if he moved just right he could tease everyone with a hint of pink with each step.

Emily looked at him hungrily and he turned away from her to bend over a little to try and get more of a reaction out of her.
