"Let's go kayaking?" Leslie suggested to Vince.
Vince lived on a big lake and it was a perfect summer weekend with bright sun, warm temperatures and low humidity. Leslie, his girlfriend of a few years now, was spending the weekend with Vince. She lived about an hour away in the suburbs but loved Vince and enjoyed escaping to his place on most weekends, especially when the weather was this nice.
"Great idea...and I'll light the grill when we get back for the chicken that's marinating in the fridge," Vince responded. He was no dummy: kayaking meant that Leslie would be in a bikini, a sight which he always enjoyed.
Between gathering up the equipment and applying sunscreen, it took maybe 30 minutes for the two of them to be down at the dock, ready to go. Both were happy to lather each other up with the slippery sunscreen, Leslie in her bikini and Vince in gym shorts. Leslie's surprise for Vince on this day was that her bikini was a thong, not her regular bikini bottoms, that showed off much of her cute ass. Vince heard a slight sigh and moan escape Leslie as he put sunscreen on her back and generously over her sexy butt, even slipping a finger inside the tiny material and up between her ass cheeks. He had her turn around and did her front for her also, slipping his fingers inside her padded top and playing with a nipple briefly. She reciprocated the sunscreen application for him but went way down inside his shorts, first in the back, then in the front.
"Oh you perv, remember who started this" Leslie said as she finished applying the sunscreen. They both looked down at Vince's front to see his shorts tenting nicely.
"That will have to be taken care of when we get back," she whispered in his ear, pointing to his growing cock and even reaching out to give it a quick squeeze.
"As will your needs," Vince whispered back and smiled.
The lake was somewhat isolated but had been discovered and developed to a certain extent. Multi-million dollar houses stood next to smaller cottages that were almost 100 years old. The residents were lucky enough to have small beaches dotting some of the shoreline, while woods and overgrowth bumped right up to the beaches in places primarily where farms still operated or the land was in a preserve. Both Vince and Leslie enjoyed exploring the isolated beaches by kayak, with Vince in one that he peddled like a recumbent bicycle and Leslie in an inflatable that she paddled and sat low inside the inflated gunnels.
Both Vince and Leslie were in great shape and enjoyed the exercise that came with kayaking, but Leslie's paddling was tough on her shoulders after a while. Their agreement was that if she got tired, she'd tell Vince and pull up next to him so he could tie her off on the stern of his kayak and just peddle them both, with her 25 feet behind him enjoying the ride.
After about an hour of kayaking, Vince could tell Leslie was slowing down. They had explored a marina and hugged the shoreline for quite a ways.
"How're your shoulders?" he asked Leslie, who shrugged as she pulled up to him.
"Sore."
Vince grabbed a bow line off of Leslie's kayak and tied it to his stern and off they went towards one of the many small, isolated beaches. Vince noticed slightly more resistance with her behind him but his legs easily peddled them forward so it was fine.
He turned around to see Leslie just gliding behind him and relaxing in the sun as she was towed.
