Back on land

Back on land, she greeted her father as he read, and he gave her a welcoming grunt, lost as he was in his book. Fuck, she wished he was concentrating as hard on her tits as he was on his book! Wait, what? Whatever, fuck, she was so horny. Nothing to do, though, she decided to lay down and work on her tan, maybe fall asleep and make this frustrating trip go faster.

As soon as she laid face down, though, she heard her father put his book down.

"Sunbathing, princess?" Her pussy trembled and gushed at this. Fuck, good thing her bottoms were already wet. She nodded, not trusting her voice in the moment.

"Here, let me get some sunscreen on you, can't have you burning up!"

Not trusting her body not to betray her, but also desperately wanting this, she just froze, and her father took this to mean assent. Her body shuddered as he came over, the unmistakable sound of him spurting some sunscreen into his hands. Was she going to let him do this? She shouldn't but fuck, did she want it.

But once again, her indecision made the choice for her, and she shuddered as he started touching her back. Luckily, he didn't realize it was from a small orgasm as her pussy exploded, just a little.

"Oh, sorry darling, was it too cold? It should heat up soon."

She could only manage a little moan, which he took as a sign to continue. His application of the sunscreen quickly became more, his hands, slightly rough, pushing in to her supple back and making it more of a massage. She groaned in pleasure and this time he didn't stop to check, just continued massaging her back with his strong hands. Fuck, this felt so good! She could feel her pussy leaking into her bikini, the now-familiar vibrations and warmth making her so horny she could barely think straight. His hands traveled down her back, eliciting more moans from her as he got closer to her ass, squeezing her sides and pushing into her back as he went, loosening her muscles and sending thrills down her spine straight to her pussy. And, she supposed, probably spreading the suntan lotion? She had nearly forgot that was what he was doing.

And she plain did forget as his hands reached her bikini bottoms and went under! His strong hands kneading her ass under the strings of her already quite immodest bikini. She could feel the material pulling away from her pussy lips, eliciting another moan as her overstimulated sex reacted to the movement. Fuck, he had to be hearing this, right? Was he trying to do this? His hands moved lower down, massaging her ass, squeezing and separating it as he continued to 'apply the sunscreen'. He could probably see her asshole and pussy, she thought. And.. and she wanted him to, too. Wanted his strong hands to reach in and touch her holes, push inside them, for her father's strong hands to explore every part of her body…

And then, suddenly, his hands were gone.

"Oh look at that, seems your brother and mom and coming back! And your sunscreen is all done, darling. Good to keep you safe!"

Katherine was so confused and horny. What? Sunscreen? Brother? Everything finally snapped back into focus as she heard her mom let out a pretty unusual giggle for her, though she could still recognize it as her mother's voice. Damn, had that just happened? Did he really do that on the beach? His hands felt so good! And she had wanted more! But was he truly doing that on purpose? He had to be, right? He was massaging her ass! But maybe he wasn't? Maybe he was just putting on sunscreen and her body just made her feel this way with the cloud of sex she'd been in for the last 24 hours? Fuck, she didn't know. But what she DID know was that she was hornier than she had ever been in her life!

Her mother and brother made it back to the blankets and sat down, and Katherine could swear that they both seemed quite sweaty and disheveled. But, they were just in the water so probably they had just horsed around, right? Right? Fuck! She thought her mom kept looking at her brother in a very non-motherly way but also she was just so fucking horny she was probably imagining it. She also could swear she could see her dad's dick struggling to escape his swim trunks but that couldn't be right, either. Sex on the brain was just so damn confusing. She closed her eyes and tried to just concentrate on nothing, letting herself tan and just fall asleep. Just like earlier, though, she couldn't shake the images in her head, of her father continuing the massage, his hands continuing their journey, then his hard cock pushing against her pussy, him fucking her from behind on the crowded beach…

"Hey there, Katherine! Time to wake up! It's getting late!"

"Wha? Huh? Oh, sorry! I guess I dozed off!"

And dozed off she had! Her body hadn't though, and she realized as she looked down at herself that her bikini bottoms were quite obviously wet just over her pussy. Fuck! Fucking wet dream. She never usually had wet dreams! This was such a weird and confusing day. She quickly sat up and put her skirt back on to hide her arousal. The whole family packed up their stuff and headed back to the car, and Katherine noticed that her mother kept walking quite close to her brother. Man, what was this? Was she somehow jealous of her mom? Now that was really fucked. She sucked her own brother's dick this morning and now was feeling possessive? God, maybe she needed to see someone. She shook her head mostly free of these thoughts as they loaded up the car and headed back.
