By the time Aidan had stepped out of the shower, dried off, and gotten dressed again, it was getting late into the afternoon. He left his bedroom and headed for the kitchen, passing by the living room and seeing Briana and Samantha huddled close together, whispering. They froze guiltily as Aidan entered.
"Hi, girls," Aidan said cheerfully. "The project all done?"
"It sure is, Daddy," Samantha said, bubbling. She held up the poster and showed him. A well-drawn progression of a book's plot, complete with colored paper cutouts and hand-drawn script font, was the result of almost two hours of work.
"Looks great," Aidan said, leaning in to inspect the poster. "What are you up to now?"
"We were just about to go for a swim," Samantha told him. His dick twitched at the thought of both teenage girls in skimpy bikinis splashing around in the pool.
"Sounds like fun," Aidan said. "Well, you go enjoy yourselves. I'm gonna probably end up doing some work in here now that you're done."
"Great," Briana said, grabbing her bag from nearby. "I'll go get changed." She left for the bathroom, bag in tow.
Once she was gone Samantha pounced on her dad. "Alright, Daddy, confess. How did you like her pussy?"
Aidan was taken aback. "What?"
"Don't try to hide it," Samantha said, giggling. "She told me about her plan to get you to fuck her. I told her we've fucked before, by the way. That's what got her interested in actually fucking you. Was she tight?"
"Uhh, yeah, she was," Aidan stammered. Samantha had stood up and backed him up to the couch, forcing him to sit down. She stood over him, then dropped to her knees and undid his belt in record time, exposing his quickly stiffening cock.
"Was her mouth good, Daddy?" she asked him quietly. "Did you cum in there?"
"Yes, baby, I did," he moaned.
"Did her mouth feel this good?" Suddenly his dick was engulfed by a warm sensation as Samantha began sucking his erection. Placing a hand on the base of his cock, she swallowed half of it easily, making full eye contact with him the entire time.
He groaned loudly, his body going limp under her masterful guidance. "I'm Daddy's special little fucktoy, aren't I?" she asked, licking his balls as she jacked him off. "You two sounded like you were having a great time in there. I could hear her moaning through the wall. It got me so wet, Daddy." She went back down on his shaft, slurping rapidly on his cock while she twirled her tongue around the head.
Aidan groaned and was getting closer to cumming again when they both heard the bathroom door open. Samantha kissed the tip of Aidan's dick, removing the precum from its head before stuffing it back in his pants. "We'll continue this later," she whispered, squeezing his hard-on through his clothes and winking.
Aidan groaned mentally. Damn! She knew how to suck dick. He'd almost cum again in the span of a couple minutes. He'd probably go finish it off watching the girls swim.
Briana walked into the living room and Aidan's jaw dropped. She wore a flimsy two-piece bikini, which showcased her full breasts and ass amazingly. The bikini was a swirling pattern of pink and light blue, contrasting nicely with her tanned skin. She paused in the entry way and Samantha ran up to her. "Ooh, girl, you look gorgeous," she cooed. "I love the support you're getting."
As she spoke, she grabbed Briana's breasts through her bikini and moved them up and down. Aidan enjoyed the view immensely. Briana blushed slightly as Samantha stepped away to get changed.
Briana smiled and waved at Aidan, who nodded his head at her. It was a little awkward; they'd just had sex, and Aidan had never been that good at post-sex pillow talk. "Your hair's still wet from the shower," he noted. "I hope you enjoyed it."
"Oh, yes, I did, Mr. Smith. Very much so," Briana said. She pulled out her phone. "We should stay in touch. I've got a constant urge that no man has been able to fill until you."
Aidan put her number into his phone. He felt mixed about this; it felt like cheating. He'd probably have to clear it with Abby first, but she'd probably say okay. She'd never kept the marriage bed too closed.
No sooner had this exchange happened than Samantha came bounding out of her room in her bikini. Hers was a vibrant shade of lavender, and because of her smaller breasts the suit covered them a bit better than Briana's. But they were still both gorgeous girls in their own ways, and looking at them now almost naked Aidan felt his cock harden.
"Alright, Bri, let's go!" Samantha giggled. "Care to join us, Daddy?"
"It's tempting, sweetie, but I've got office work," Aidan said.
Samantha pouted. "Aww, come on, Daddy. Come for a quick swim. Hanging out with two beautiful teenage girls is definitely better than doing boring old paperwork."
Aidan sighed, then got up off the couch. "What the hell, I'm a world-class procrastinator anyway," he said chuckling. Samantha squealed and jumped up and down in excitement. Then she and Briana ran outside and cheered as they jumped into the pool.
Damn, it's hot as hell out here, Aidan thought as he stepped outside and was struck by a wave of heat. He began to strip off his shirt as the girls' heads poked out of the pool to observe. He noticed Briana blush slightly as her eyes made contact with his muscles. All his working out had paid off. Now clad in only a pair of sports shorts, he jumped into the pool after the girls.
The water felt just as amazing the second time. As Aidan came up for air, Samantha surprised him with a splash attack. He splashed his daughter back, and pretty soon the three of them were engaged in an all-out splashing war. Because Aidan was bigger than the girls, and because he'd been in a lot of splash fights, he quickly began to overpower the girls, who made a quick escape underwater. "Chicken!" he taunted.
Moments later they popped back up on the other side of the pool. Briana had a worried expression on her face, while Samantha was grinning broadly. "Daddy," she said in a low voice, "your thingie is hard..."
As the wavy water settled Aidan noticed that the momentum of the pool water had made him very hard. He also noticed that Samantha had pulled his shorts down during their escape. The little trickster. He looked back up to the girls but only saw Briana; Samantha had gone underwater again.
Suddenly he felt something on his cock. Samantha had a firm grip around its base and was blowing air bubbles onto the tip. The sensation caused Aidan to fall back against the edge of the pool, moaning in pleasure.
She came back up and took a breath. "Samantha, what are you doing?" he asked.
