"And is there something you would like to try before we commit? Because I have something I want to do before we change us." Michael looked surprised.
"What do you mean?" Sarah bit her lip and moved her hand down to her pussy, and spread it.
"I want you here." Michael didn't understand.
"You want me to lick you? Because that..." Sarah cut him off.
"No, I want to be fuck by you one last time before we, you know." Michael now understood what she meant.
"Yeah, of course. I think I have some things I want to do." Now it was his turn to stroke her cheek.
"Maybe we should work this out until Wednesday and then see where we come?" Sarah nodded her head, and they kissed with the taste of understanding on their lips.
They spent the rest of the night talking until they both realized it was way past midnight and decided to sleep. The talks continued early the next morning, and they were way too engaged to realize that it had become noon before they even made an effort to make breakfast, so it became everybody's favorite meal, brunch. They spent the day half-naked in bed, part-time talking and part-time fooling around with intermediate breaks for food and such. When Sunday was about to tick over till Monday before they had discussed enough, and they had outlined how this new phase of their relationship should be.
They had agreed that from Wednesday forward. They would no longer be boyfriend/girlfriend but roommates. They wouldn't sleep in each other's beds unless Sarah made an invite to her bed. The other way wouldn't happen because Michael's was too small for two. Michael would be locked in the chastity of a time of Sarah's choosing and to which she held the key. Sarah could fuck around with who she wanted on the condition that Michael would be notified and discuss logistics. They were going to work up so that he would be able to participate, either watch hidden in the closet or in the open, depending on the situation, but that wasn't decided yet.
They would no longer use each other's name but refer to each other as Princess or Miss for Sarah and Cucky or Roomie for Michael. The given name should only be used when there is something important, and it should be a kind of safeword. The safeword would be "swotch." Michael demanded that Sarah should be harsher towards him. Michael couldn't make any sexual requests, and Sarah would control his sex life, and she would allow him regular orgasms. She needn't say when he would be allowed to orgasm but with some frequency. They would have weekly meetings with how things were going, but they would become less frequent as time passed, and they became accustomed. Sarah would decide which rules the household should have and could institute new rules as she sees fit but could be overturned by the meeting. So basically, their relationship would be reset and play it as Michael newly moved into the apartment where Sarah lived.
Those were the stipulations the two could agree on, and they wrote them down just to be safe. They made two printed copies and put two dotted lines on each, mostly for posterity, but they both agreed that they should sign it on Tuesday night before they went to sleep. Just to finalize it. They also agreed that they would have one evening each where they got to try some last fantasies or things they wanted to do in the bedroom as boyfriend/girlfriend before Wednesday, within reason, of course. Michael's was Monday evening, and Sarah's was Tuesday evening.
Michael's evening wasn't spectacular, but he wanted to tie up Sarah, tease her, and then have her be edged, and to end it all, he wanted her to perform oral on him until he came. They both had great fun and, for once, did Michael lead. He wanted Sarah to get a taste of what it was like being edged and not being allowed to cum. They did not have penetrative sex because he rightly assumed that Sarah wanted that to be the big crescendo on her night, so he tried to save himself a little for that.
Sarah's evening was more intense. She wanted to fuck the living hell out of Michael for what could be the last time as boyfriend/girlfriend. So she started the evening by rubbing some premature ejaculation cream on his penis in the hope that he would last extra long and that she could maximize the time penetration would happen before Michael would inevitably cum. They would have to take a break from "regular sex" and entertain themselves with other acts. It must have been an effective cream because Michael fucked her like a stallion and bounced back remarkably quickly, and the sex was rough and animalistic. She was determined to remember every part of his dick. And he every aspect of her pussy.
They had set the alarm for five to twelve, so they could sign the "contracts" before the new day, and their new lives would begin. They dug up the papers and signed both of them, and kissed.
"Congratulations, Babe, you were amazing tonight, but now you are my official cuck, and I love you."
"I love you too." They kissed once more. They had prepared sleeping tablets for each other so they could sleep and slid under the covers gazing lovingly into each other's eyes, holding hands, and butterflies in their stomachs.
