Diana was updating her computer diary, describing her weekend assignment. She was naked since Don was home. He had made love to her twice since breakfast, once with just her and the second time with both her and Lee. Right now, Lee was serving him in the master bedroom. The mistress was supposed to be home this evening at 20:00. She typed in her duties for the day: Housework, sex with the master, exercises, etc. When she finished her diary, she checked her schedule and found an evening assignment for Wednesday at 19:00. Will be delivered home, at 8:00 Thursday. There was also a fashion show "300 miles drive, two nights in motel me (Marg), Diana and Jackie. Diana to model swimsuits. Leave 17:00 Friday return home 16:00 Sunday." It sounded like an adventure to her. She wondered about her Wednesday assignment.
Lee came down from her session with Don, a dreamy smile on her sweet face. She always wore that expression after an orgasm "The master wants us in garters and stockings for 20:00 when the mistress arrives. You better come for a shower now, sister." She wiggled her naked rear end at Diana, teasingly beckoning her to follow.
"I'm going to spank that thing if you don't stop it." Lee replied by doing a seductive bump and grind, sticking her tongue out at Diana.
"I dare you, try and catch me first." She said running down the hallway, looking back sticking out her tongue again. Diana ran after her into the dressing room where Lee was standing now in the spanking position. Diana gave her two playful taps and Lee put her arms around her neck kissing her passionately. "Sorry sister, I was a bad girl." Diana kissed her playful sister, squeezing her tiny body passionately.
"You're a little tease but I'm so happy you're my sister. I hope that the mistress will promote you soon, so I can serve you too." "I can never accept a promotion sister, I want to serve you." They kissed again hugging each other tightly. "We better get ready, before we do something we don't have permission for."
They met their mistress at the door to the garage, holding hands as usual. She put down her suitcase and stretched out her arms. The girls flew into her embrace, Diana being taller kissing her first. Lee reached frantically on her tiptoes smacking her lips. Diana stood aside smiling as her sister kissed her six-foot mistress. Lee threw both arms around Margs neck and held on as Marg straightened up again, one hand one her rear end, supporting her weight. "Not fair," Diana said, pouting jokingly, Marg drew her in with one hand and kissed her. "We have all night, girls but thanks for the welcome. I really missed you two. I supposed my husband has kept you busy today?" They both nodded, looking knowingly at each other. "Well I can always read your diaries, your weekend assignments should be interesting reading."
After they bathed their mistress, she made love to her husband. Diana and Lee stood next to the bed hand in hand, watching the couple make passionate love. After they finished, Lee cleaned her master's penis and Diana sucked the mistress's vagina. They lay in each other's arms enjoying their orgasms as the girls serviced them. The sisters were then told to make love to each other, while Don and Marg watched them. They climaxed quickly and were then told to get on top of their master and mistress, Lee on Marg and Diana on Don. The four of them hugged and everybody kissed everybody. No one got much sleep that night and breakfast was very late the next morning.
On Wednesday evening, Don dropped Diana off for her assignment at an apartment building and told her 913. She pushed the appropriate button in the lobby and a lady answered.
"It's Diana to see you."
"Come on up," the door buzzed and she let herself in. She wondered on the way up in the elevator how many people would be there and if there would be other sex slaves. The weekend had been exciting, with that master and mistress and their male slave. The door was ajar when she got there; her mistress had told her to walk in when that was the case. She closed the door behind her and was told by a woman's voice coming from inside the apartment to just hang up her coat and enter the living room. The lady, about thirty with short dark brown hair was sitting on a couch, sipping a glass of wine. She appeared to be slender and tall. "Hi Diana I'm Dot, sit down here," she padded the couch next to her. "Yes mistress, thank you very much." she sat down and straightened her knee length skirt.
"I want you to call me Dot, OK."
"Yes mistr..., I mean Dot," She said, almost uncomfortably. This kind of treatment took her by surprise. She looked around the room, as if expecting someone else.
"No sweetie, I'm alone, it's just you and me tonight." She smiled reassuringly, "you thought I was a sister for a minute didn't you?" Diana nodded, leaning back on the couch, a bit confused. "Would you like some wine, I know Marg allows a little and I won't smoke, she hates that."
"Just a small glass, please and I don't mind if you smoke." Diana answered with a coquette smile, her eyes sparkling in anticipation of making love to this beautiful woman. Dot rose and picked a glass out of a server.
"I don't need it tonight, I have all the drug I need right here" She smiled at Diana as she poured the wine, her face inches away from hers. Diana smiled back, not getting the meaning and sipped on her wine. "What kind of music do you like."
