The result.

Beth smacked the coin out of the air, and onto the back of her hand, and impressive feat given her drunken state. She slowly revealed the face, {if Coinflip = 2

"Tails, Private Kyle."
"Damn... and it's Corporal."
"Exit the pool, Corporal Jackson."

Beth leaned on the lip of the pool and admired the muscular back and well shaped ass as water fell away in sheets from Kyle's body.
"Front and back, soldier..." she called out.
Kyle sighed. "I'm not a piece of meat, Beth..." but he obliged, and Beth bit her lip at the sight of the thick, hanging cock. Kyle's hands twitched towards his crotch, but he stopped himself and planted them on his hips instead.
"Get enough of an eyeful?"
"Oh, don't be such a buzzkill." She smirked. "Now, stand over there, by your clothes."
"And turn around, I know..."
Beth climbed out of the pool and walked to her towel, continuing to enjoy her view while denying the same to Kyle.

"Well, guess it's heads. You win."
"You can just get out, I won't look..."
"Those were not the terms, Private Jackson."
"Corporal."
"Corporal." she swam past him towards the steps. "Don't turn around. And don't close your eyes."
"Yes, ma'am."

Beth slowly climbed out of the pool, reveling in the feeling of Kyle's eyes as the feasted on the sight of her naked body. It was a thrill. She slowly bent down to pick up her towel, absolutely exposing her pussy to him. She heard him clear his throat.
"Alright, I'm going to dry off over here, not looking..."
Beth heard Kyle exit the pool and start to dry off, and she made a point to slowly and sensually dry each leg, accentuating her body.

They dressed, and then sneaked back to the townhouse. When they reached the door, Kyle put his grabbed the handle, stopping her from sliding the door open.
"What was this about, Beth? Tell me the truth."
"What? We're just drunk... having a little fun." Kyle's eyes bored into hers, and she sighed. "Look... things haven't been.. the best between Brian and me recently, okay? I'm feeling a little... unfulfilled. A little neglected. I just... I wanted to do something... a little naughty. So I don't have to feel like the rest of my life is going to be full of frustration and disappointments."
"How is skinny dipping with me helping that, exactly?"
"I don't fucking know, alright!" she sighed. "I'm sorry. I... didn't mean to yell in your face."
"Look, my brother's not perfect, but I can tell when he loves someone. And it's for real with you. So my advice is to be patient, and don't do anything stupid."
"...sure..." she knew she was pouting.

Beth left Kyle in the living room, heading upstairs to take a quick shower in order to get the chlorine off her. She slipped into bed beside her snoring fiancee, but she laid awake for a while, thinking about what Kyle had said to her.
