*Although Samantha is only in her late 30s, I've chosen to keep this in the mature category because of the age difference. As always, I'd love to hear your feedback in the comments or directly to me. This one took me much longer to write, and I hope you guys enjoy it! *

When Keith woke up the next morning alone in Samantha's bed. He slipped on his boxers from the previous night and walked into the kitchen, where he was greeted by an incredible sight. Samantha was standing in front of the coffee maker in a bathrobe, short enough that it couldn't quite cover her large ass. Even in a loosely tied bathrobe, her body was curvaceous. How she could maintain her hourglass shape, while having an ass like that was something he could only attribute to good genetics and luck. She had a body that women 15 years her junior would die for. She turned around, showing him her gorgeous smile as their eyes met.
"Excuse me, I didn't see you there. Coffee?" She held up a coffee mug, her bathrobe being pulled up even further as she raised her arm, exposing the tight lips between her legs.
Keith stood for a moment, silent and dumbfounded. It had been much darker last night, and this was the first time he had really gotten to appreciate her body.
After a few seconds of stunned silence, he responded "Yeah, I'll take one if you're having one."
"Good."
They made idle conversation for a while, Keith couldn't keep her eyes off of her and she could feel his gaze constantly drinking her in. She started to feel a wetness between her legs, so she got up and walked around the table standing next to him.
"Mind if I take a seat?" Samantha said, gesturing towards his lap, his already hard cock showing through his boxers.
"Please do," He said with a smile.
She sat on his lap and they continued to chat about nothing in particular, not addressing the night before. He could tell she wasn't wearing panties and could feel the outline of her wet lips starting to wrap around his cock, which was twitching at the thought that a thin layer of cloth was the only thing between them. As they were talking he could feel her start to rub back and forth across his dick, soaking the crotch of his boxers, and making him quietly moan.
Samantha turned around, "I think I could use a little cream with my coffee if you don't mind.", she looked at him slyly.
Keith didn't even answer, he quickly slipped his cock through the slit in his boxers and bent her slightly forward as he stared at her ass. She moaned as he entered her, sliding in easily as he had the night before, her pussy well lubricated already.
She started to ride him in the kitchen, the sunlight shining through the window, giving him a great view as her ass bounced up and down on him. He loved the way her ass jiggled, just enough to let you know it had some weight to it. Her pace started out slowly, her moans matching her pace, long and deep. Soon though, Keith started to feel the pressure building between his legs.
"I'm about to cum," He managed to get out between labored breaths.
Samantha didn't respond, just picking up her pace, her ass now loudly slapping against his thighs. He reached around her, untying her bathrobe and grabbing her F-cup tits, squeezing and massaging them. She moaned as he started to play with her nipples, pinching them lightly. Her legs started to shake and she rode him through her climax, her insides squeezing his cock rhythmically as it coaxed the cum out of him. He came shortly after she did. She could feel his warmth filling her up, driving her to a second orgasm at the thought that she had just made this man shoot his seed inside of her. She trembled as she got off of him, his cum dripping out of her as soon as his cock slid out.
She reached down, running her finger through the cum that was dripping out of her. She slipped her finger between her lips, tasting their combined juices. Keith admired her body for the umpteenth time this morning, taking her all in.
"Yummy, what an eventful morning," she said with a wink.
The rest of the day continued as was fairly normal. Keith went into work, and Samantha watched soap operas and sipped on coffee. As she was getting up to make herself lunch, the doorbell rang.
"Who could that be?"
She walked over to the door, tying her bathrobe, and pulling it down, trying to keep herself decent. She opened the door to a sight she had not expected. Standing there was a woman in her late 20s, much smaller than Samantha, especially in the areas that seemed to matter to Keith. Besides that though, she was very pretty. She had a pixie cut that was dyed blue at the ends, and a nose stud that matched her face very well. She might not have had the same assets as Samantha, but she could tell that the woman was in good shape and probably had a very well toned body under her tight clothes.
"Hi, is there something I can help you with?" Samantha asked, puzzled who this woman was and why she was at their door.
"Hi, yeah, I'm looking for Keith, is he around?" the woman said, looking suspiciously up and down at Samantha. She had not expected a scantily clad, albeit gorgeous, woman to answer the door when she came by to see Keith's new place. Had Keith lied to her?
"No, I think he went to work earlier this morning. I can take a message for him though if you want," Samantha said, staying calm, cool, and collected on the outside.
The woman smiled, "Just let him know Catherine came by. Oh, and I'll leave my number for you in case he wants to get in touch."
"Okay I can do that. Anything else?"
"No, just let him know that I dropped by to see him."
Samantha took down her number, awkwardly said goodbye, and closed the door, puzzled at who this woman could possibly be, and how Keith hadn't mentioned her during the time she had known him.
Samantha tried to keep busy throughout the day, but her nerves were getting to her. Who was this woman? Why hadn't Keith ever mentioned her? Was she his girlfriend? It didn't seem like it, he didn't seem like the type of guy that would just up and leave his girlfriend and then jump into bed with another woman. Besides that, he had mentioned that he hadn't been with another woman in awhile. It wasn't adding up, and she was nervous about confronting him about it tonight.
The time finally came for Keith to get home, Samantha sat on the couch watching TV, not really paying attention, but trying to seem busy. Keith walked through the door.
"Hey how was your day?," he asked.
