To be the third wheel on a date.

On Friday, Sarah announced her weekend plans during breakfast.

"Hey, Roomie, I'm having my boyfriend over this weekend." Michael stopped what he was doing and looked up, worried.

"Will I... Do I have to, you know..." Sarah looked at him, feigning uninterest.

"It's up to you. If you want to stay at the apartment, you'll have to make yourself useful and accommodating. If not, then you will have to make yourself scarce." Michael realized that this was the next big step in their play. Sarah was inviting him to watch her with her man. He felt both intrigued and scared at the prospect, but there was only one answer he could or wanted to give.

"I want to... You know, stay." Sarah eyed him sharply. She was clearly gauging if he understood what he signed up for.

"I think I should tell you what I expect from you if you decide to stay." She squared her shoulders and began. "First off, this evening is for me and John. He threw a lovely party for me the other weekend and made some commitments, so I want to reward him for that. If you stay, you are simply here to facilitate help, serving dinner, drinks, and other conveniences. Secondly, and this goes without saying, Whatever I say goes. If I tell you you should do something, then you will do it. I don't want any talking back. You are here as a privilege, and if you don't like it, you may silently leave and not return until Sunday evening. Thirdly, and this might be obvious, during the weekend, we are not equals. You are here to serve, which means honorifics, and 'Yes Sir' and 'Yes Ma'am,' you are here on my behest. Is that clear?" Michael stood there and gulped. Sarah was going hard, and her demands were quite extensive, but he felt that this was something he couldn't pass up.

"Yes, Princess. I understand. I am your **** servant for the weekend." Sarah smiled inwardly at Michael, using the old honorific.

"Good, and a to-do list will be waiting for you when you get home today." She finished her meal and got up to get dressed for the day, feeling butterflies in her stomach. When she reached her room and closed the door, she made a small sound of happiness. She had done it! Michael really said yes to submitting to her with John. Her body was buzzing with excitement. This was the first time her two "boys" would meet with all their senses, and knowing what they were like made her even more excited.

Sarah got dressed, and she took extra care picking out something special. She picked out the most expensive blouse that John had bought her and matched it with a skirt and some black stockings, then snapped a photo to him while hinting at what was underneath and the text. "Guess who will be joining us and serving on our date on Saturday, Hun?" John answered her with an affirming text and a picture from his perspective on his knees. He had started to take this type of photo ever since the party. It was as if something had solidified in John's brain, and he had become more everything. Every message he sent was accompanied by him doing something submissive, whether on his knees or the like. He never sent dick picks unless she commanded him to, but some were rather suggestive and bold, and once she swore that he had taken it stripped down in his office, but she wasn't sure.

On top of that, he had insisted on her having a stipend each week and suggested that he could open a credit card for her to use. After some persuading from him, she reluctantly accepted the credit card and the sum of money. She hadn't looked at the sum but suspected it was a tidy one.

She hadn't talked to Michael about it yet, but she suspected that John was starting to take their relationship more seriously. And he was the "perfect" boyfriend, rich, handsome, and doting. But Michael was still... What was he? A roommate, a ****, a servant, a boyfriend, a cuckold? It was hard to put a label on their relationship by now, but she knew that whatever happened, Michael was her partner, and for as long as he wanted, she would continue to be his cuckoldress.

She finished her makeup and left the apartment, catching Michael's lusting eyes as she passed him out the door.
