Spotting the open boardroom door, Rachel was about to walk in when she heard first Sandra's moans, then Tom's slurping noises. Rachel peered in; neither noticed as Rachel saw Sandra's back and straddled legs and then heard Tom uttering the words Rachel would never forget, "Cum again for me Sandra."
Rachel left the office quickly and quietly, tears streaming down her face. How she got home that night was a blur. Rachel acted like all was fine when Tom returned home later that evening; he gave the excuse that he was late due to some work he had to catch up on. When her sister arrived with Keith later, Rachel didn't say a word about what she saw.
"Did you have a nice day Sandra?" Rachel inquired sarcastically. Sandra said she enjoyed herself shopping and had met up with Keith later. And made out with Tom, Rachel added to herself.
Retiring early due to being tired so she told the others, Rachel lay in bed and cried. She thought about what transpired at Tom's office and knew what she would do.
Rachel waited until the time was right then she set her plan in motion. It had been a week since catching them. Sandra went out shopping with their mother; Rachel made an excuse to stay home.
Keith sat in front of the TV, his legs stretched out on the coffee table in front of him. Rachel came downstairs wearing a black lacy negligee, nothing underneath. He gazed at Rachel's voluptuous body through the sheer material. She moved alongside the sofa Keith was on, his eyes following every movement she made. Leaning over, supposedly to get the TV listings on the table, Rachel pretended to lose her footing and fell right onto Keith's legs.
Rachel turned her face and looked straight into his eyes. Keith's attention was diverted to her breasts. Rachel reached over and kissed him right on the lips and then stuck her wet tongue inside. Keith responded to her probing tongue with unexpected passion. Revenge would be sweet, Rachel thought to herself. Her yearning body knew that it was far more than about getting even.
Keith had been lounging in his bathrobe. Rachel dropped to the floor and knelt down. She started massaging his legs; she moved her hand all along his muscular form as she made her way up to his stirring prick. Slowing tickling his inner thighs and opening his legs wider as she proceeded, her face reached his pronounced cock.
Embracing his cock with one hand, and stroking his balls with the other, she opened her hungry mouth and with it engulfed his balls. "Mmmmmmmmmm," Keith moaned. As she continuing sucking on it, she moved her hands up and down his throbbing rod.
"Suck my cock, baby," Keith urged. Rachel released his heavy balls and went to his thriving prick. She licked all along the shaft, which made it flourish; Keith's pulsating tool jumped uncontrollably as she licked the side of his instrument. "Oooooohhhhhhhh God, baby. Fuck that feels great," Keith uttered.
Rachel generously salivated Keith's swollen cock head and then she swirled the tip of her tongue around his hole. Keith's reaction was swift, "Baby suck my cock deep. NOW." Rachel went to his needy cock. She wanted to feel his black hard and thick prick in her mouth as much as he wanted it there.
Rachel took his erect manhood inside her wanting mouth and closed her lips around it. It felt so good there. As she sucked on his dick, she anticipated how that huge cock would feel inside her pussy. She wanted badly to have it there. She took Keith's cock deeper and deeper until his cock felt the back of her throat. He couldn't hold back any longer. His big load of hot cum shot down her throat. She swallowed most of it. Keith looked over at Rachel's contented face, his cum dripping out of her mouth.
He reached over and put his tongue in her mouth, tasting himself as the remnants of his cum lingered there. There was urgency in their kiss as their tongues hungrily explored each other's mouth. Lifting Rachel first onto the sofa, Keith then picked her up and carried her into the kitchen. Placing her on the edge of the kitchen counter, her legs straddled over it, he rubbed his expanded prick head along her wet slit.
He teased her cunt until she begged, "Please fuck me Keith." Keith penetrated her pussy hard and fast, over and over he thrusted inside her. In, out, in, out, "OMG, fuck me, fuck me. Give it to me," Rachel screamed out. Keith held her legs to get in deeper. He could feel the intensity of her multiple orgasms as her pussy tightened around his cock. She shook as each one took hold. "I'm cummmmmmmming again," Rachel said; Keith came in his sister-in-law's dripping cunt as her climax covered his cock.
Keith and Rachel were startled to see Tom standing there, fixated. "Rachel how could you?" Tom shouted. "I came home to pick up something I forgot and this is what you do when I am at work?"
"No different than what you did with my sister," Rachel retorted as Keith lifted her off the counter. "Sorry Keith. I caught Sandra with Tom last week. They were having sex at Tom's office." She looked over apologetically at Keith.
"Actually Rachel, I already knew. Sandra and I have an open marriage and she told me all about it. In fact, she knew I wanted to sleep with you and I will let her know we did. This arrangement works well for us," Keith admitted.
"I see. I think Tom and I need to talk privately. Please excuse us Keith," Rachel said. Keith left them alone and went out for a drive. Rachel and Tom discussed what she saw at the office that day. For the first time, Rachel and Tom really communicated. Rachel confessed she hadn't been enjoying their sex life for a long time. Tom said although he did enjoy it, there was something he felt was missing. They both agreed that they needed some marriage counseling.
That was the turning point for Tom and Rachel's marriage. After Sandra and Keith returned home, Tom and Rachel went through months of marriage therapy and went to a sex therapist to improve their sex lives.
Rachel opened up for the first time in their marriage about what she liked and disliked during their lovemaking. How could Tom be expected to satisfy her when she didn't tell him her sexual preferences? They experimented with different positions. Therapy taught Rachel and Tom that it takes two openly communicative and loving partners to make sex as enjoyable an experience as possible.
Tom rarely worked late anymore. He hired an assistant to help with his workload. Marriage was Tom and Rachel's top priority.
Sandra and Keith came to visit again when Rachel and Tom celebrated their 25th Anniversary. Nothing sexual took place between any of the in-laws and what happened so long before was never spoken about again. None of them would ever forget their family reunion.
