This story is a continuation of "In-Laws on Display" which appears in the Exhibitionist and Voyeur Section. To understand the motivation and background of the two persons in this story, I would recommend you read that one first.
The opportunity finally arrived for Kurt and Amber to get together. After stripping naked for one another following a night at the bar, they realized how much each had the hots for the other. They were able to change their work schedules, arranging to have the same days off during the week. Fortunately for them, they both held down jobs where they had enough seniority that they could choose when they would be working and which days they would be off. Tuesday and Wednesday were the days they settled on and, after what seemed to be interminable waiting, the first of the Tuesdays arrived.
"Okay, I'll be right over," Kurt told her, after being told on the telephone that Amber was ready and waiting for him. The two couples lived on opposite sides of the same block, and an alley ran through the block, dividing it in half. Each back yard had a gate that opened onto the alley, and Kurt quickly strode through his and over to Amber's. As arranged, it had been left unlocked for him, as had her back door. He entered her back yard and locked the gate behind himself.
"Amber?" Kurt called out, once he was inside the kitchen, with the door securely locked. He noticed she was apparently so eager to get it on with him she had left the breakfast dishes on the table.
"I'm upstairs. In the bedroom. C'mon up."
It was all he could do to refrain from sprinting up the stairs, Kurt was so eager to enjoy the lovely body that had been displayed to him just before they agreed to a series of trysts. Making the arrangements had taken almost two months, but they both expected the sex to be more than worth the wait and the trouble. Staying as cool as he could, under the circumstances, he strolled to the door to the bedroom where he knew Amber would be waiting for him.
"Amber?" he called out again, much more quietly this time.
The door slowly opened. The shades were down and the lights were on, and the beautiful sight that met his eyes was the same as he remembered from that night months ago. Completely naked, and smiling an invitation to him, Amber stood just inside the doorway. Behind her was the bed, where they had been unable to do what they both wanted so much to do back then. It was freshly made, with clean sheets and extra pillows, but no other coverings.
Kurt was not over-dressed himself. If he had been seen during his transit between his house and Amber's, he wouldn't have wanted to arouse any suspicion, so he was wearing a shirt and pants and shoes, but with no underwear or socks. After a few second's rapid activity of two pairs of hands, he wasn't even wearing that much. Completely naked, the eager man and woman sat down on the bed.
During the earlier mutual stripping they had done for each other, Amber had yearned to take Kurt's handsome cock into her mouth and do what her husband was too doltish to appreciate. As a young virgin, she had sucked off all her boy friends, and even some casual acquaintances, because she enjoyed it so much, possibly even more than they did. When she had tried to do the same to her husband on their wedding night, he was scandalized, and told her that only whores did such a disgusting thing. Most of the men she had sucked off had been delighted to reciprocate, and eat her pussy. They had brought her to some momentous orgasms, but she decided it would be better not to even ask it of her bridegroom, and he made no offer then, and none since. He very foolishly thought of a woman's genitals as being indecent, even repulsive, and didn't ever want to see her unclothed.
She didn't bother to ask Kurt, because she was certain he would be more than happy to have her suck him off. His cock had been partially erect while on his way over and, when he saw the beautiful, naked woman waiting for him, it became fully hard. While he sat on the edge of the bed, Amber got to her knees on the floor between his legs, and smiled up at him.
Knowing what she was about to do, Kurt grinned at her. He loved being sucked off, especially by a beautiful woman such as Amber, but his wife absolutely refused to do it. "Our mouths are made for the partaking of food," she always said. "And using them for anything else except communication is a disgusting perversion." Kurt's wife was very much like her brother in their attitude toward sex.
Not even a little bit did Amber share that opinion. She rested her elbows on Kurt's thighs and held his cock gently in her fingers. "Scoot forward," she told him. I want to give you a good licking."
The smiling Kurt moved forward, lying back with his ass hanging over, eager for this special treat. Amber was eager too; it had been too long since she had done what she was about to do, especially to a man with as nice a cock as Kurt's. Holding his shaft so it would be out of the way of her mouth but would still rub against her face the way she liked, Amber started by licking his crotch. Working slowly forward, her tongue caressed the whole area between his ass and his scrotum.
Kurt murmured happily. It had been so long since a tongue had been anywhere near that part of his body that he had almost forgotten just how good it could feel.
Amber looked up at him with her pretty, dark brown eyes and smiled. She didn't say anything; his sounds of pleasure answered any question she might have had, and she was enjoying herself as much as he was. Amber loved the feel of a man's private parts on her tongue and lips and all parts of her face. She moved in closer, and started licking along one side of the base of his scrotum, holding his hard cock against her cheek and making it even better for her. When she reached Kurt's untrimmed pubic hair, Amber licked her way back down the side, around the base, and up the other side of his wrinkled ball sack. As she licked that side, her other hand held his cock against her other cheek.
Kurt loved everything that was happening to him, beginning with walking into her bedroom and finding his naked sister-in-law waiting for him. He relished the feel of her tongue caressing his balls, and he was especially happy that Amber was obviously having as much fun as he was. That day promised to be one of the best of his life, and he resolved to give just as good a time as he was getting. It got even better when her mouth started fondling the underside of his scrotum. When she got to one of his balls, Amber gently held it between her lips and licked it, sending thrills through his body. His other testicle got the same treatment and, when she started licking in front, she even enjoyed rubbing her nose back and forth against the underside of his hard shaft.
