"Why would I need a vibrator? Ben leaves me sore on a daily basis with his constant attention. He's like a puppy that hasn't been fixed, constantly trying to nuzzle and explore my sex. I don't know, maybe things were different when you were with him..."
Ben's cheeks reddened at Kim's portrayal of him as anything less than a calm, experienced, and collected stud.
Beth felt a wave of anger rise within her as Kim's "joke" grew within her mind to cloud her consciousness with rage. Kim also thought it was hilarious to play with the fact that she was less than a year younger than Beth as a means to "explain" why Ben was going to marry Kim. They were finishing a meal at Ben and Kim's place, a common occurrence among the three friends.
"So, I guess, you know, Ben's just 'in' to younger women!" Kim proudly concluded.
Beth slapped Kim's face just as the last word was leaving her lips. Kim looked shocked, then stammered "Why did you, did you do that? I'm, I'm sorry, Beth..."
"No, you're not, not yet at least. Ben, I can see now that the expected levels of discipline and respect have fallen since I moved out, and I can't stand by and let this continue. Go into the bedroom and reflect on this. Kim and I will be in later."
Ben looked to the side, confused by Beth's behavior, then left the dinner table in a manner intended to convey condescension and superiority. "He's choosing to mock me," thought Beth, as her anger continued to grow, becoming like another person controlling her actions.
"Beth, I'm really sorry, I LOVE you, I would never do anything to hurt your feelings..." Beth slapped Kim again, leaving her with a stunned expression on her face. "Beth?" she said, as if she were having trouble recognizing her friend.
"Kim, you need to shut your mouth and do as I say. Your impudent attitude is disrespectful, and must be corrected."
Kim did love Beth, that was true, and to an extent that she found confusing, given that she'd always thought she was "100% heterosexual." If they were honest with themselves, they would have to admit that while it was Ben and Kim who were to be married, Beth was becoming an integral third party to every aspect of their marriage, including sexual. Now Beth's behavior was confusing Kim, but also arousing her, as her (fairly hard) blows had opened the door to another possibility for their relationship. Fearing another hard slap, Kim kept her silence.
Beth crossed the living room to the sofa and sat down in the middle. "Come over here, Kim."
Kim complied, standing in front of Beth, actually shaking slightly. Kim was dressed for hot weather, with a short, soft cotton skirt that under most conditions was able to cover her curving buttocks, but under other conditions, her thong panties beneath were unable to prevent the world from catching erotic glimpses of the lower curves of her beautiful ass. She loved knowing that her bare buttocks were sliding freely across her skirt as she walked, allowing their true shape to be visible to all without the unnatural confines of traditional panties.
"Lay across my lap," instructed Beth. Kim obeyed, and began to find comfort in the passivity that Beth's orders were creating in her. Now she didn't have to think, just do as she was told, and Beth wouldn't be angry at her...
The first slap across her bottom took her breath away, and the pain brought her back from her unrealistic fantasy that she could be a detached observer to Beth's play.
Wordlessly, Beth continued her attack on Kim's hapless ass. Her skirt had fallen down past the tops of her buttocks, coming to rest across her lumbar region, and the peaks of her muscular yet shapely buttocks were now turning red under Beth's blows. Beth held Kim in place using her left hand to squeeze Kim's breast uncomfortably hard.
As Kim's passivity had turned to fear, it now began to turn to lust. She became aware of only three things: the sound of Beth's palm smacking against her buttocks, the localized pain that came each time then melted into general pain across her buttocks, and the feeling of her thong insinuating itself between her moistening labia. Her sparse red pubic hair was becoming slicked down along her swelling labia. She began clenching her cheeks together and wriggling her bottom to try to provide some sexual relief to herself.
"What are you doing? Are you getting turned on, you little hussy?" demanded Beth.
Mortified, Kim whispered "Yes."
"What?!" barked Beth.
Kim cleared her tightening throat. "Yes," she said in a louder voice.
Beth increased the ferocity of her blows, forcing Kim to break her chosen erotic rhythm of writhing and rubbing in response to Beth's punishment. Now she could only grimace as the pain became unbearable, and she started to cry, her tears being wicked into the fabric of the sofa that was pressed against her face.
Beth could keep this up indefinitely. She loved to rock climb, and her body was deceptively strong despite her voluptuous hourglass appearance. When climbing, she preferred to wear a thin Spandex running suit that took the form of shorts and a sleeveless top in one, providing just enough coverage to protect her from her climbing harness. She found a bra and panties to be unnecessary when wearing it, and as she would sweat her way up the rocks, it was common for men to watch her beautiful hips and buttocks flex and extend, and observant parties could even perceive the outline of her labia between her asscheeks as her suit became wet with sweat. Ben noted that it was not uncommon for ostensibly straight women to watch Beth's assents carefully as well, their glazed eyes beginning to focus on events inside their minds instead of the world outside. He would sometimes wonder at night if these same women were making love to Kim in their minds at the same time he was making his way towards climax inside of her.
