She wants to sit on your cock in the pool
From Create Your Own Story
She wades over to the stairs and perches on one of them. "You sit on the stair, daddy, and I'll sit on you." She giggles excitedly. You smile and run into the house to grab the lube. After spreading it on yourself liberally, you sit on a shallow stair where the water won't wash the lube off of you. Valeria squats down while facing you, pulling your cock so that it sits under her. You hold her waist to help guide her, and she nestles your cockhead against her opening.
"As slow as you want, sweet one," you tell her, letting her take the next step. She takes quite awhile, poking and prodding her sphincter with your rod before it finally slips inside her and she bites back a whimper. You kiss the soft valley of her cleavage and lick her nipples gently, trying to give her some distracting pleasure. She sinks down on you bit by bit, speeding up towards the end in her impatience to get to the bottom. She exhales when she bottoms out, her fat erection resting against you.
"Mmm, all the way in my ass," she says, drawing out her words. She bounces once experimentally, screwing her face up as she gets used to you. Her cock bobs and slaps your abs and chest as she gets into it a bit more, loosening up her newly stretched rectum. After trying this for awhile, her legs start to get tired, so you pick her up and wade into the pool. You put your back to the side wall, and she braces her feet next to you. Her arms go around the back of your neck, and you cradle her so that you can pull her down on your cock. With the water carrying more of her weight, she enjoys this position much more, and soon she is moaning as she rocks atop you. You find her prostate and concentrate on hitting it as much as possible. "My ass feels so good, daddy," she mumbles, and you kiss her throat in response while you twist your pelvis and grind your cock around inside her. "My pussy and my clit feel so good, daddy," she says louder, and you fuck her hard, returning to her prostate. She groans wordlessly for a couple of minutes, then her eyes fly open. "Daddy, please..." she begins, and you cut her off.
"Yes, baby, go ahead." She pushes her butt to you, so you keep yourself deep inside her while she trembles. Her cum drools out of her in a heavy, constant flow, her prostate being milked by your member in her ass. She collapses back to the surface of the water, breathing heavily. She smiles weakly and whispers, "Thank you, daddy."
You are about to respond when her hand goes instinctively to stroke her cock. You slap her wrist, then tweak a nipple, hard. She squeals in pained surprise. "Bad girl!" you yell at her. "I gave you a nice, long cum, and that's how you repay me? I thought I made it clear in the living room that you are not to touch your clit, especially while I'm in your pussy!"
Looks like she needs to learn a lesson:
