The two men watched as their wives writhed in ecstasy on the double bed in front of them. Jen was the submissive one, naked already, on her back, with Ana between her legs, still fully clothed.
Ana was not very interested in men, and sex with her husband was more a chore that she wanted to get over with as soon as possible than anything else. She was very attracted to Jen and these "encounters" were the only thing that kept her going. The sexual dynamics between them were perfect; moreover, these swinging sessions drained her husband completely and, after one of them, he usually wouldn't pressure her for sex for a week or so.
Whenever the opportunity presented itself, Ana would just go nuts, using each and every such occasion to satisfy all her needs as a woman. She would probe Jen's every orifice, savor every inch of her skin, and make her cum until she could literally take no more. Jennifer, on the other hand, was quite the opposite. She was really into men, and loved her husband very much (hence the willingness to go to any length to please him) and, even though an orgasm was often denied her, she enjoyed sex with him.
With Ana, she would just lie there, and let the other woman do whatever she wanted to her. Jennifer would reach new levels of ecstasy when Ana's finger would slide up her ass, when Ana would thrust her tongue into Jen's mouth and kiss her for at least some ten minutes, when Ana would just continue holding off her orgasm, keeping her on edge, teasing her endlessly until, when she finally did let her cum, Jen would hold on for dear life, and pray that her little heart wouldn't burst.
That night, Jen was lying on her back, Ana between her legs, which were flung over her partner's shoulders. Ana first licked Jennifer's thighs, her tongue gliding over the soft skin, making Jen grab the headboard and raise her hips to allow access to her more intimate parts. Jen liked to cum; she loved her orgasms, and didn't like it when Ana teased her, but she was a certified bottom and would never interfere in whatever her lover was doing to her. Even when Ana would keep going after Jen had climaxed, she would simply lie there with her eyes closed and her body trembling from the intense stimulation, but she would never try to stop her.
In fact, this is how Ana had made Jen squirt for the very first time. It had been a very long session for them - Ana had been very frustrated; her husband had taken her anally for the very first time the day before, and it had not been a pleasant experience for her. He had been too aggressive, and didn't even ask or even warn her, for that matter. He just rolled her over onto her back, spread her ass cheeks, and shoved his cock in. Clutching the sheets tightly in her hands, Ana had buried her face in a pillow, tears continuously running down her face while he just humped away, squirted his juice in her bowels, got up and left.
She rolled up into a ball afterwards, angry tears having their own way. On the following night, Ana took out that frustration on poor Jen, rubbing and rubbing and rubbing her little clit until Jennifer shuddered all over and the sweet nectar gushed out of her loins. This only fired up Ana that much more; she stroked her sub's clit with all the more intensity. Jennifer grunted - the only time she ever did that, for she was usually a silent lover - and Ana would have made her pass out, but Jen's husband pulled her back, and proceeded to fuck her for a full ten minutes, ejaculating twice in the process.
Ana had watched from the side of the bed as he pounded her and, when he was done, she lay down beside her and stroked her hair and face. Ana enjoyed this period of time immensely. After the men had spent themselves, they usually forgot their wives existed and proceeded to busy themselves in a little snack or a popular sport on the television, for the men liked their sports. This is when Ana got the opportunity to snuggle up to Jen, feeling the warmth of her body, and the sweet, sweet smell of her sex.
