As I walked outside, I saw that my cousins and my sister had all collected next to my dad's car. Cassie and Isabella weren't wearing their glasses, so they presumably had their contacts in. They were all wearing oversized t-shirts, same as Cassie. These outfits accentuated their thighs well, a problem given that Sarah and Isabella both had really nice thighs. Sarah's were more toned, long, and graceful, whereas Isabella's were more plump, soft, and erotic.
As I approached the car, however, my dad came around the corner of it with fishing poles in hand, and said,
"Oh, Jake! I thought you were still sleeping. I wanted to fish at the pond, and the girls said they wanted to swim, so I said I'd take them! Why don't you come with us?"
He then noticed my swim trunks.
"Oh, looks like you already knew. Alright well hop in."
He then put the poles into the backseat.
Quickly counting how many people were coming, I asked,
"Is there really gonna be room for me?"
Puzzled, Dad looked at the car and the girls, and then said,
"Oh wait you're right. Hmm."
Right on cue, Cassie chose that moment to saunter over, looking more than a little pleased with herself, as she said,
"Of course we can all fit! I can just ride on Jake's lap!"
Dad asked, concerned,
"Are you sure? I could always just go fishing some other time."
Cassie waved her hand dismissively.
"That wouldn't be fair! It was your idea to begin with to go fishing! It's not that long of a car ride, and I can tough it out until we get there."
Dad shrugged.
"Okay, if it's alright with you all."
I was beginning to get both excited and trepidatious. I looked at Cassie, and she smirked at me, smugly.
I sighed.
"That's fine with me, I guess."
"Great!" Dad said. Everybody pile in!"
We all began getting in the car. Dad sat in the driver's seat, Sarah took shotgun, Audrey sat on the passenger's side with all the fishing poles as she held them, I sat on the other side, Isabella sat in between us, and Cassie sat on top of me.
"Everybody comfortable back there?" Dad asked.
"Yup!" Cassie said, wiggling around in my lap as if she were getting comfortable. My dick started to become hard, and she wiggled in response to it, feeling it up, which only caused it to grow harder. As the car started and we headed out, Cassie kept wiggling as if trying to get comfortable, and whenever she found an excuse to do so she would find new ways to apply pressure to my dick, such as leaning forward to show me some cows, or pretending to slip off of me for a moment when the road got bumpy.
After this, she pulled her shirt up to her waist, revealing her red thong string nestled between her perfect white ass cheeks, put my hands on her waist, and whispered to me, just loud enough for Isabella to hear,
"This shirt is making me slip. Hold me so I don't fall off."
I felt like this was totally nonsensical and bound to make others suspicious, but there wasn't anything I could do about it without making a scene, so I just held her while she gave me this torturous lap dance. Thankfully, most of the others weren't paying attention. Sarah was talking to my dad about fishing, and Audrey was looking out the window at the scenery, particularly the flowers. Isabella seemed to be listening to the conversation happening in the front, but every so often when Cassie would pull something like this she would look over at us for a few moments. Horny as I was, I desperately wanted to grind Cassie onto me, but I knew that if I did anything like that Isabella would catch it for sure, so I had to remain stock still while Cassie tormented me. Even the pale skin of her exposed lower back and the shape of the shoulder blades beneath her shirt looked absolutely tantalizing as her hips continued to rotate on top of me, and the smell of her hair right in front of my face was mind-numbingly intoxicating, but I was absolutely powerless to do anything about it. She couldn't remain moving all the time, however, so often she would simply remain still, pressing downward, her crotch pressed directly onto mine through our swimsuits. Just when I thought this constant stopping and starting was going to drive me into madness and cause me to start humping her in full view of Isabella, we finally pulled to a stop in front of the pond.
Sarah looked back at us and asked,
"You holding in there alright?"
"Yup!" Cassie chirped. "It was harder on me than I thought it was gonna be but that's okay, it was actually pretty fun!"
As she said this, she opened the door and jumped out, leaving me there with a full erection tenting my shorts.
Sarah's eyes traveled down, landed on my erection, and then rose back up to meet mine. Her face was totally impassive.
Lighting fast I jumped out of the car, eager to escape that gaze. My dad and the girls all got out next.
We all began discussing where we should go. Thankfully, this is the largest pond on the property by far, it was practically a small lake, so there was plenty of water for both fishing and swimming to occur without disturbing one another's goals. It was decided that Dad would go to the far end of the pond, while the girls and I would swim just off the dock. Dad left, walking out of sight, while the girls and I made our way to the dock. Cassie got there first, and as she did so she pulled her t-shirt over her head, arms crossed, leaving her in just her red thong and tiny red string bikini halter top, as she put her hand on her hip cocked to one side.
The rest of the girls followed suit, pulling their shirts over their heads. Sarah wore a tight v-neck green one piece that accentuated her long legs, narrow waist, wide hips, and pretty breasts. The back portion was exposed, revealing the impressive musculature in her strong back. Isabella wore a blue one piece with white polka dots and a ruffled skirt. As modest as that sounds, there was far too little fabric for Isabella's features, as most of the flesh of her huge tits were still exposed, the middle portion was tight enough to show off her impressive curvature, and the skirt did little to hide her sexy plump ass. Finally, Audrey was revealed to be wearing a fairly standard pink bikini with a blue design on it, but it still was flattering for her C cup breasts and athletic 5'6 build, and the colors went nicely with her green eyes and blonde hair. Her ass was larger than Cassie's, but it still had a very firm, rounded shape.
As they undressed, Audrey said,
"Jeez Cass. That suit's pretty risqué."
"Yeah yeah, well, I like to feel the elements on my skin, plus, I feel sexy wearing it."
Cassie leaned over, letting her tits hang down in her top, as she blew Audrey a kiss.
