Her back

Jesse decides to start simple and work his way towards his main goal, her ass. The sun was shining directly down onto her, illuminating her pale skin and making her dirty blonde hair glisten like liquid gold flowing down her back. Reaching up, Jesse's hand slowly slid up her spine, making Daisy shudder in anticipating. Rolling over her thin bikini strap, he grabbed her loose hair and pushed it all over her left shoulder, moving it out of his way and exposing her upper back to him.

"Daisy?" he said, trying to get her attention.

"Yeah?"

"I'm going to have to untie your bikini bra in order to rub your back," he explained, his eyes transfixed on the smushed titflesh spilling out from either side of her torso.

"Oh, o-okay, I guess that's fine," she said, becoming increasingly aroused. Jesse grabbed hold of her strap with one hand, and the feeling of his fingers gracing the nape of her back made her massive dick throb in anticipation, audibly creaking the pool chair and straining its straps. One tug was all it took to undo the knot in her bikini, and brushing aside the straps finally revealed her entire back to him, in all her glory. If she were to stand up right now, she'd be completely naked, in front of both Jesse and her family, and that thought along with the feeling of Jesse straddling her ass gave her cock a second, strong throb that strained the chair once more.

"Jesse...." she moaned, her eyes closed as she bathed in her ecstacy.

"This is going to be a bit cold at first," he said with a smile, taking enjoyment from giving her pleasure. With a pop the sunscreen bottle's cap flipped up, and Jesse noisily squirted out its contents into his hand. The thick, white fluid pooled into his hand, and he couldn't help but be reminded of the thick, white fluid that Daisy shot all over the pool chair next them. Jesse would be lucky to shoot a load as big as what he just squirted into his hand, but her obscene cock beats both of them out by several magnitudes with her pre cum alone. Jesse didn't know why, but thinking about it all made his cock as solid as steel, and he was blushing wildly. The tip of his tent fell perfectly into the crevice that was created where her ass cheeks met her thick thighs, an opening that snaked all the way down into her ass. Putting the sunscreen bottle down, Jesse lathered his hands together quickly before leaning forward to start applying it. As he did so, his shameful boner gliding in between her cheeks like a train running down a set of tracks. He slid in perfectly, and as his hands met her back, his cock was being hotdogged by her huge trunk all over again.

"I'm in heaven," he thought, his hands sinking into her soft, supple, feminine skin above her shoulder blades, slowly working in circles as he painted her back white. As Jesse worked his magic, Daisy quietly cooed into her folded arms. When he pressed his crotch into her ass and began rubbing her back, her ginormous, uncut cock throbbed hard, this time blasting a couple liters of steamy girl sperm all over her feet, the chair, and splattering on the patio floor like a shotgun spread. Daisy was too blissful to care about her obscenity, and Jesse couldn't hear her cock blasting her kids all over the ground over the sound of sunscreen rubbing and Anna swimming in the pool.

Eventually, after a few minutes, her shoulders and her entire back have been rubbed in, the white sunscreen turning clear and coating everything from her hips up. Now, Jesse was practically drooling as he picked up the sunscreen bottle again. He loaded his hands up with twice the amount of sunscreen that he used before, all of it necessary for the leap in surface area going from her thin, petite back to her massive, rippling, record breaking ass. He took a deep breath in, and as he breathed deeper and deeper, he felt himself getting more and more horny. The air carried the scent of chlorine and sunscreen, of course, but there was this warmth around him, a scent like someone mixed the best parts of sea spray and fruit. It was such an alluring aroma that he continued to pause to take in another deep breath, the salty smell driving his boner insane as it twitched and throbbed into her asscheeks with his every heartbeat. He wanted nothing more than to rip his trunks off and stuff his aching prick deep into her tight, dripping pussy. He wanted to fuck her with everything he had, he wanted to breed her and impregnate her womb in front of her own mother and sister, and he wanted to hear her scream his name and beg him to do it...

The sensation of something cold running down his forearm ripped him back to the reality, and as he looked down he saw that the sunscreen started to ooze out of his palm and down his arm as he daydreamed. Looking around, Jesse realized that not only was he smelling the violated pool chair next to them, but he also realized that she had shot another bucket of pre cum behind them, and the aphrodisiac smell was washing over them as a light breeze carried it to his nostrils.
