I've read a number of revenge type stories on Literotica and had to add my own.
It was the Friday of a long week and Jen's last day of employment. Her lay off came with a generous separation package, but she was unprepared for depression that overwhelmed her as she loaded her desk into a cardboard box. And she had to pick up her husband that evening at the airport as he returned from a business trip. Jen hated driving to and from the airport, especially on a Friday night. Her husband Jack had bribed her with dinner at a fancy restaurant to celebrate her new beginning.
Jen had picked out her sexiest dress and stockings, a set she knew would make Jack hard, especially having been away all week. She was finishing the final touches on her make up when her cell phone dinged for a new message. Jen didn't recognize the number and almost ignored the message. But maybe it was from Jack using someone else's phone, so she clicked on the message. Slowly, a picture appeared that sent Jen to her knees.
Jack was in the picture with a naked woman sitting on his lap. The woman was licking one of her breasts and pulling on the other nipple. Only Jack's face was visible so Jen could not tell if he was also naked. He had that fake look of shock on his face she had seen many times before like when he forgot to put down the toilet seat.
Jen's mind was racing, she was already depressed but the depression now turned to anger. She threw a bunch of clothes into an overnight bag with the intention of heading to her sister's. As she was walking out the door, she received a text from Jack saying he was on the ground and would be out as soon as could get his bags. Jen sent him the picture and a note saying, "fuck you, walk." Then she turned her phone off and pulled the battery.
Jen's sister Mary introduced her to Jack, and she still lived in the house they grew up in. Her parents had retired to Florida and gave the house to Jen and Mary. Jen had moved out when she got married to Jack. She ignored the strange car in the driveway. She was surprised that the door was locked and more surprised when her key would not work. After several minutes of pounding on the door, Mary finally opened it and Jen barged in.
Mary was standing there in a see-through baby doll with no panties on. Her hair was a mess, and the smell of sex was obvious. Jen blurted out that Jack had cheated on her and showed Mary the picture on her phone.
Mary said, "I have company Jen."
Jen said, "I don't care, it's our house."
As she sat down on the couch, Jen saw a naked black man walk from the master bedroom and enter the bathroom. She noticed two things, he was well cut and well hung. Mary had always been the more conservative of the two and that she was fucking a black man was shocking and it was only seven o'clock in the evening.
"Who's that?"
"That is Dionis. Let me get you a glass of wine."
"Bring the bottle," said Jen
While Dionis exited the bathroom, he gave Jen a smile and made sure she had a good look at his cock. Jen and Mary were both petite, with people often thinking they were twins. Jen could not imagine that that thing could fit into her sister. Dionis was still standing there when Mary returned with a glass and a bottle of wine. She poured Jen a glass and then turned to look at Dionis."
"Look," said Mary. "I have to finish some things and I'll be out in a little bit."
Dionis scoffed at the comment. As Mary tried to pass him in the hallway, Dionis gave her a smack on the ass, pulled the baby doll over her head and tossed it in Jen's direction. Jen noticed that her sister had several handprints on her ass already. The pair disappeared into the master bedroom.
Jen drained her glass and then a second glass. She realized she had not eaten all day when the wine hit her stomach. She was beginning to think the day could not get any worse when she began to hear the sex sounds coming from the master bedroom. It became clear that Dionis was trying to push his cock into Mary's throat, but she was having trouble.
"Forget it" said Dionis, you'll never be able to please a black man and if you can't deep throat my cock, you can never be a black cock slut."
Mary said, "Please don't give up on me, you know how much I want this. Please try again Dionis."
"We've been trying for weeks bitch and my balls ain't getting any closer to your face."
"Please, one more try? Please, just shove it in."
Some ouches came from Mary and then just muffled sounds came from the bedroom. Jen had a vision of Adonis holding Mary's hair as he forced his cock into Mary's throat. The vison had made Jen's nipples harden which were clearly visible through the thin material of the dress.
"Good girl" said Dionis, "Now let me fuck that face."
Mary was moaning, Jen wasn't sure if it was from pain. Based on what she saw, Jen imagined that Dionis' cock must deep in Mary's throat. On cue, Dionis announced he was going to shoot his come directly into her stomach. A few minutes later Dionis asked if she liked that.
"I love to please you Dionis, but I also love the taste of your come."
"You love the taste of any black man's come."
"Yes, but I love yours the most."
These revelations were too much for Jen and she decided to go get a hotel. But when she stood up, she realized that almost empty bottle of wine had made it impossible to leave. Her sister was the good one, perfect grades in high school, aced the SATs and graduated law school at the top of her class. Jen had the quite the reputation in high school, more for sucking dick then fucking. Fucking came after she met Jack. Now her sister loved the taste of black men's come.
There was another slap sound from the bedroom and Dionis said, "Bring that ass over here and get on your hands and knees, I have another load of come ready for that cunt of yours."
The sounds that emanated from the bedroom reminded Jen of an interracial porn movie she had watched with Jack once. Dionis was slapping Mary's ass, asking her if she liked his big black cock in her cunt. Jen could hear them so clearly, she wondered if the bedroom door was shut. She wobbled over and tried to peek around the corner. The door was wide open, Dionis' back was towards her, and he held a handful of Mary's hair as he pounded into her.
Dionis slapped Mary's ass again and asked, "Are you my slut, my white slut for black cock?"
"Yes," moaned Mary.
"You going to continue fucking my friends?"
