Sven the younger sighed audibly as the old boat slowly came about on the sun-dappled water. Concentration etched on his face, he sailed as close to the wind as the boat's ancient rig would allow. The old lug sail was no longer the most efficient of rigs; now, in the light summer breeze that wafted between the islands, its age and weight allowed for little more than sailing too and fro. What was gained on one tack was lost on the opposite.

As the remainder of the fleet of dinghies with their more up- to-date rigs sailed slowly into the distance, towards the finish line and the afternoon tea and sandwiches that the regatta day promised, they could only watch.

His girlfriend, Kate, giggled as she said, "They'll think you did it on purpose, like running out of petrol!"

Sven looked worried for a moment, and then said, "They will, won't they? I hope they don't tease you - us - too much."

She laughed. "Well, if they're talking about us, they won't be bothering some other unfortunate, will they?"

She stretched, making herself more comfortable on the bottom boards of the boat. She had spread the sail covers out along the gratings to make sure she didn't get marked through her bathing suit. As the suit tightened a little across her bottom, the lines of her sex were plainly visible, and Sven strained to look, without making it appear obvious. From a distance Kate was almost invisible, with just the top of her head appearing above the boat's gunwale. Sven, up on the aft seat, had positioned himself on the boat's lee side so as to help the sails hang and catch the wind better in the light breeze. It didn't seem to be making any difference.

"Lee - o", he muttered as the boat got to the end of the beat, and slowly round they came and started to lose ground again.

Kate squinted along the deck line and laughed. "We're going backwards again!" Facing back to watch Sven's face, it was difficult to read her expression, her eyes hidden behind the sun glasses. She stretched her bare foot out and ran it along Sven's calf.

"Hey, don't do that - I can't concentrate as it is," he said, desperately trying to contain his thoughts and steer his mind away from the growing erection that his swimming trunks were failing to contain, let alone hide.

Kate giggled again, "What's the matter? Getting too hot? You're going pink in the sun!" She laughed, running her toes up the inside of his thigh. She reached the top and brushed her big toe over the lump that was visibly forming. "My - what's this, I wonder?"

She moved forwards on her hands and knees, and the top of her swimming costume tried valiantly to mask the beautiful breasts than Sven knew were inside. He groaned and, giving up the struggle, moved his own bare feet to her sex. Now it was Kate's turn to whimper, as he ran his toe along the crease of her vulva, down underneath to her sensitive anus. She wriggled and her tits wobbled invitingly before Sven's eyes.

Kate ran her hands along Sven's thigh, and he gasped as she reached his trapped erection. She moved forward and kissed the tip of his penis through the cloth, and Sven felt his heartbeat in his ears as he sang to himself with the pleasure of her touch. He closed his eyes as she slipped her fingers underneath the waistband. Sliding her hand inside his trunks, she moved them down while he eased his bottom off the seat until she could remove them. His penis came free, and Kate now kissed the tip, gently using her lips to remove the pearly drop that had formed. Slowly she eased Sven's foreskin back and took the sensitive head into her mouth, running her tongue round its rim. Sven lay back in the sternsheets, everything subsumed in the waves of pleasure emanating from Kate's treatment of his now overwhelming need.

"God, Kate, I can't hold... stop!" Everything was forgotten but the rising tide that was trying to break free. As he started to buck his hips in time with her suction, Kate scratched his wrinkled sac with a long fingernail. It was too much, and Sven erupted into Kate's hungry mouth. She gently sucked him dry and then cleaned the tip of his penis with her lips.

They looked up and realised the boat had edged into the reeds at the extremities of one of the islands, out of sight of the others and in no danger of moving off anywhere. Sven let go of the tiller and stroked Kate's hair as his penis shrank to a more normal size.
