Her own twin

And then she saw her, a woman sitting alone on a beach towel just a few feet above the tide line. She looked so much like her real body that for a moment Susan that it might be Jon in her body, but as she approached, she could see the differences. She was a little older maybe, and a little more athletic. The stranger's boobs were a little smaller, but had significantly larger nipples.

Susan found herself drawn to this woman and made her way across the sand.

"Anybody sitting here?" she asked.

Her look-alike looked up, her eyes stopping and widening a bit at the sight of Mike's big black cock.

"My husband...uh...well, no...my husband is sleeping in this morning," she said. She scooted over slightly on the towel and smiled. "I guess you can sit here."

Susan already felt her semi-erect cock stiffen as she sat down on the beach towel. There was room for them both, only if there legs touched ever so slightly.

"Can't believe your husband let you come out here alone," she said and the woman giggled. "My name is Mike."

"I'm Sheila," the woman said. "He's being an asshole. We had a fight so he canceled our couple's massage plans and went back to bed."

"Sounds like a dick," Susan said.

"Yeah...really big dick," Sheila said, her eyes going back to the now fully hard big black cock next to her.

Susan just wanted to pounce on her and fuck her the way she had always wanted John to take her, but she held back. Sheila had clearly been married for a while and this was new to her. She could make this happen, but she had to approach this carefully.

"He was probably just being a dick because he was jealous," Susan said. "Probably didn't want someone else rubbing all over his beautiful wife's body. Touching her better than he can."

Sheila giggled and blushed. Her eyes drifted back to Susan's big cock.

"I can't blame him," Susan said. "I mean...I would be jealous too, but a woman like you deserves to get whatever you want."

God she just wanted to fuck this woman, but she wasn't just some easy beach slut like Carla. Bedding her suddenly felt like a challenge and she wanted to win it.

Susan reached over with one hand and suddenly started to rub Sheila's neck. The woman stiffened a first, surprised by being touched by a stranger on the beach, but she quickly relaxed.

"Oh God that feels good," Sheila moaned.
