Tina comes outside

Tina walked out of the house. “Hi!” she greeted us, hurrying over to join her brother and I.

“Good morning, sweetie,” I said.

Tina had come out to the pool without much in the way of supplies: no towel or sunscreen, just a pair of sandals that she kicked off once she was out on the deck, leaving her completely naked.

“Ooh, sunscreen!” she said, spotting the bottle I had next to my lounge chair. “Can you put some on me, Daddy?” she asked, coming over and sitting down on the side of my chair.

I wasn’t an idiot: I realized she was trying to skirt the boundaries of her “no-sex-with-Dad” rule. But I personally wasn’t in much of a mood to be a stickler about it, so I didn’t call her out on it. “Sure, sweetie,” I said instead, and took a few minutes to rub sunscreen onto my youngest’s naked body.

Seeing that I was busy for the moment, Joey borrowed my phone with the picture of his grandmother and took it to a nearby lounge chair to lie down and jerk off while I was busy with his sister.

I got Tina’s skin covered with the sunscreen, not lingering on her small boobs, her ass, or her pussy, as much as she did her best to encourage me to do so. “I think I need some more down here, Daddy,” Tina said, turning so that her butt was pointing towards me and bending over. “Make sure to get it into every crevice!”

I gave her butt a playful smack instead. “None of that, young lady,” I chided her. “You want any more, you can put it on.”

Tina sulked a bit, but gave up on her blatant seduction efforts and went to lie down on a neighboring lounge chair instead. Knowing that it would only seem like I was deliberately torturing her, I refrained from going back to jerking off after I was done lotioning-up my daughter. I glanced at my still-unsatisfied hard-on and sighed. It was seeming more and more like I wasn’t going to get it taken care of until Joey’s friends came over. Oh, well. At least that meant I’d be sure to give Sandra one hell of a performance.

Caitlyn joined us out by the pool a few minutes later. Unlike her sister, Caitlyn came well-prepared for a morning of serious tanning: a towel, her own small bottle of suntan lotion, sunglasses, and her phone.

Joey immediately began to ogle his older sister’s big, exposed tits with a grin when she arrived, which made Caitlyn sigh dramatically.

“Hey, Katy, can I fuck your tits again?” he asked her pleadingly.

“Absolutely not!” she declared. “After last night, you’re lucky I’ll even let you look at them.”

Joey grumbled, which made Tina and I both chuckle at his self-imposed misfortune.

“What about you, Daddy?” Caitlyn offered. “You can fuck my tits if you want,” she offered sweetly, batting her eyelashes, but if was obvious that her offer was more a ploy to tease her brother than out of any genuine interest in playing around with me.

Joey and Tina both grumbled darkly at that offer, so I decided to head things off to avoid any further family infighting.

“Okay, okay, let’s not fight,” I said in my “Dad” voice. “Caitlyn, don’t tease your brother. Cut him some slack. Let the boy fuck his big sister, huh?”

My oldest daughter cast me an annoyed look, but then she appeared to get an idea. Walking over to the deck chair where Joey was sitting with his hard-on in his hand, she turned around and straddled his waist in the reverse-cowgirl position, grabbing her brother’s stiff prick and sinking her pussy down onto it. “There!” she declared. “See if you can surprise me with a facial now!” she challenged, and then began to writhe her hips.

Joey didn’t answer with a taunting comeback this time. Instead, he merely groaned with please at her gyrations while he reached up to fondle his big sister’s huge chest from behind.

Tina promptly got up off her lounge chair and bounded over to the side of mine. “Can I ride your cock, too, Daddy?” she offered eagerly.

“You know the rules, sweetie,” I reminded her firmly.

“But you’ve got that hard-on, Daddy! I can’t just let you sit there with it while Caitlyn fucks Joey!” Tina protested.

I gave my youngest a sardonic look, quirking one eyebrow at her. I wasn’t buying her logic, and she bit her lip when she saw it.

“Well … how about we just do it like last night?” she suggested. “I’ll sit on your lap, and you can rub your dick against my butt. No fucking,” she promised, holding up her right hand as if she were swearing in court.

I resisted for a moment, but then, sensing weakness, Tina settled down on my lap in a similar position as her older sister was sitting on their brother’s lap in the next lounge chair over, then wiggled back until my stiff cock was pressed right up between the cheeks of her cute, pert butt.

I sighed. “Okay, sweetie, fine. But let’s not tell your mother about this, hm?” I suggested. I squeezed some sunscreen lotion into the crack of Tina’s ass and then used my thumbs to hold my pole in place, while I used the palms of my hand on the globes of her ass to squeeze her cheeks around me, and began to hump my daughter’s ass-crack. Tina, meanwhile, used both hands to play with her pussy at first, but after a few minutes, she slid one of her hands even lower underneath herself, and began to toy gently with my balls instead.

The four of us fucked for a few minutes, until a loud moan from Joey had Tina and I looking over to watch while he came into his older sister as she rode him. Caitlyn was using a few fingers on her clit to make sure her own orgasm wouldn’t be far behind.

“Cum on my ass, Daddy!” Tina encouraged when she, too, began to cum as we watched her sister writhing in the throes of climax.

Realizing that I was being left behind, I redoubled my own efforts, and gave a dozen or so additional hard, fast strokes between my youngest’s ass-cheeks in order to drive myself to orgasm. When I got there, I simply let myself go, spurting cum all over Tina’s ass and lower back while I continued to thrust, until I was finished. I would probably have told her “no” if she’d asked, but Tina didn’t bother making sure it was allowed before she turned around and sucked whatever cum I had left straight out of my dick. I decided that a lecture just then wasn’t worth getting her upset, so I let it go.

As I was relaxing with my cock softening in my youngest daughter’s mouth, I saw Caitlyn get up off her brother and walk towards the pool.

“Hey, now!” I called out to her. “What do you think you’re doing?”

Caitlyn looked at me, confused. “Swimming?” she answered, obviously not sure why I had stopped her.

“Not with a pussy full of cum, you’re not,” I chided her. “I don’t want our new, clean pool water all full of cum on the very first morning.”

Caitlyn heaved a long-suffering sigh. “Come on, Daddy. What, you want me to go inside, take a shower—douche, even—before I can go for a swim?”

“You can do what you want about it, but the rule is: no cum in the new pool,” I insisted.

Caitlyn sighed again, but then her gaze fell on her brother, and she grinned. “Okay, no problem,” she agreed happily.

I eyed my oldest daughter warily, suspicious at the sudden turnaround, then watched as Caitlyn walked back over to the deck chair where Joey was still lying.

“Okay, your turn for an unexpected facial!” she declared while quickly straddling her younger brother’s face.

Joey flailed his arms a bit when he realized what she was doing, but too late: Caitlyn was already sitting on his face and had him pinned.

“Okay, buddy: you’re gonna eat my pussy until there’s no cum left to mess up Dad’s pool, and I’m not getting up until you’re done,” Caitlyn informed her brother.

Joey’s only response was a muffled grunt, and a half-hearted slap against his sister’s ass.

Tina and I laughed, then watched Joey eat his sister out. It was clear after the first few seconds that Joey wasn’t really all that unhappy with his big sister’s plan, since his previously flaccid cock had resurged into full erection as he ate his creampie out of her.

“Do you wanna lick your cum off my ass, too, Daddy?” Tina offered. “I wanna swim, too.”

I glanced away from Caitlyn sitting astride her brother’s face to look down at my youngest daughter’s cum-covered butt, next to me on my lounge chair. “You know, cum on your butt isn’t like having a creampie, kiddo,” I pointed out. “You could just wipe it off with a towel.”

“But I didn’t bring a towel,” Tina pointed out, while getting onto all fours and wiggling her bare butt at me, giving me a mischievous grin over her shoulder.

I sighed, realizing that I had already succumbed to temptation. “Okay, okay: you win,” I told my youngest. I leaned forward in the chair and took her pert butt in both hands, then bent forward. Rather than bothering to lick any cum off her right away, I went right for her pussy, peeking out from beneath her ass, and started to eat my daughter out, knowing that was what she really wanted.

“Oh, Daddy, yes!” Tina exclaimed happily.
