Sheila on top

"I've always wanted to do this...but Barry is really not big enough," Sheila said. "He just slides right out."

She swung a leg over Susan, and then impaled her pussy on Mike's big cock. It slid in much easier than it had the first time, but she still went slowly so as not to hurt herself. She was cumming the entire time.

"Jesus Christ," Sheila moaned. She was now just sitting atop Susan not moving, and she was still orgasming. "I-I've...always heard...once...you...go black that...fuck...that, uh...that you...never go back."

"Well is that right?"

"I don't...shit...I don't know," Sheila said. "This is life changing. I had no idea how much I was missing. All these years and I've only been with Barry? I may as well have been married to a woman. If I went back now, he wouldn't even be able to feel my pussy. His little penis would just vanish inside of me."

She grabbed Susan's hands and started riding. After a moment her eyes rolled back in her head and she just went for it. Susan could do little more than watch as the woman basically used Mike's big cock like a sex toy, grinding years of sexual frustrations out.

In that moment Susan felt like she completely understood Sheila and where she was coming from. Years being loyally married to the same man but never being really satisfied on the bedroom.

Then the other woman's entire body began to shake as she achieved the much anticipated "big one." Her moan turned to a scream and her pussy clamped down like a vice, causing Susan to cum, filling her with cum for the second time.

Sheila collapsed atop her, her head laying on her chest. Susan wrapped her arms around her and held her, happy to have been the one to finally give her the sexual gratification she had needed.

Then she frowned as a thought dawned on her. Although they may look alike, she and Sheila were not the same, as she had just thought. At least John tried hard and could get her off occasionally, it sounded like Barry couldn't care less about Sheila's needs. Barry was just worried about his own needs and his own orgasm...the same as her.

Was she really the bald, fat man on the beach with the tiny penis? Had she really spent their entire marriage making her husband into Sheila, a submissive who never got to have enjoyable sex?

They lay there for some time in silence.
