Astrid was coming down the gravel path, her hands carrying a pair of towels and yet another tub piled high with dirty dishes. "Man, these kids just make such a mess," she complained obliviously. "I swear they've used every single dish and mug we brought. Here - shift over, Sarah, I've got this. Most of this mess was made by my kids after all."
Sarah - still catching her breath, Bill's cum still sliding down her leg - moved over mutely and let Astrid take over at the washing up sink.
"We've been waiting for you Bill," Astrid complained. "The fire is almost out. Weren't you getting wood after your shower? What took you so long?"
"Um .. yes. I was cold and the hot water just felt so .. nice," stammered Bill, who had by now put his towel back on. Sarah could still see the faint outline of his still hard cock. "I'll go get that wood now." He flashed a dark glance at Sarah as if to say - we're not done yet - and headed off to the campsite manager's office.
Sarah wondered how much Astrid had seen. Nothing, it seemed. Astrid seemed preoccupied with the dishes. Too preoccupied to notice the flush on Sarah's face, the fact that her bikini and coverup were askew, and the tell-tale smell of sex that seemed - to Sarah - to permeate the air around them. Her heart thumped in her chest as she contemplated what had just happened: Had she just let herself be fucked - magnificently - by Bill outside a public washroom? She wasn't a cheater - she loved Ted - but what had happened had been so sudden, and, she admitted to herself, it had felt so good. So, so good. And yet, they had both risked good marriages for 5 risky minutes.
Astrid started humming as she washed the dishes. Her mood seemed improved now that Bill had been packed off on his campfire task. "Hey, Sarah, go get your shower before I use up all the hot water here," she said as she motioned to the towels. "I'll get these done and then I'll join you. I brought you a towel 'cause I bet you need a shower - you've been on the beach all day."
Sarah mumbled her thanks, picked up a towel and headed into the communal showers. Each washing block had a sink outside for dishes, and separate male and female shower and toilet blocks. It was late and the showers were deserted. Sarah stripped off - grateful for a moment of privacy. She ducked under a hot stream of water, sluicing off the still sticky cum on her thighs before Astrid came in.
The hot water needled her skin, reviving the guilty memories of Bill's touch. As she stood under the stinging spray, going through the motions of cleaning herself, all Sarah could think about was how he had penetrated her - as if he had read her mind and had known that all she needed was to be bent over that sink and fucked like a bitch in heat.
