The sunlight prodded Abby awake early the next morning. She noted a mild headache from the rum drinks she'd had at the tiki bar. In the bed next to hers, Michael was sound asleep. Given the heat, the sheets were bunched around his waist. Abby admired her brother's lean, muscular frame.

As memories of last night flooded in, guilt and desire coursed through her in equal measures. Abby, wearing only her underwear, careful not to wake her brother, grabbed her clothes for the day and retreated into the bathroom.

A couple of Advil and a tall glass of water restored Abby's physical state, but mentally she was at sea.

She turned on the shower. Once hot, she stepped under the waterfall showerhead and gave a quick thanks to the heavens for a really nice resort bathroom. The hot water was like an elixir. For a few minutes, she did nothing but luxuriate in the shower. As best as she could, she shut out her internal thoughts and focused on the physical sensations she was experiencing.

Once she felt a bit more grounded, she lathered up some lavender body soap and set to washing her body. When she rubbed her hands over her breasts she nearly gasped at the pleasure. Her hard nipples begged for attention. She couldn't remember her breasts ever feeling so sensitive.

"This island," she muttered to herself. Her thoughts turned to her brother. How had that happened? Had she and her brother really masturbated to each other last night? Of course the answer was yes, it was all etched in her brain: Her brother's truly massive cock; the way he stroked it while looking at her; the way he looked at her. Pure lust. Had she looked at him like that?

Abby felt weak in the knees. She teased a nipple as one hand, as if on auto pilot, slid down to her pussy. She slid a finger into her wet opening. She was on fire. She could feel an orgasm building, even though she'd barely touched herself.

She remembered just how her brother said, "I want to fuck you!" And how she had replied, "I'd love to feel that big cock fill up my pussy!" She knew in that moment if her brother had gotten up and tried to fuck her, she would have spread her legs and begged him for it. But he didn't fuck her; he pumped his cock until he came. That first rope landed on her and she licked it up like a depraved slut.

Abby could feel her orgasm approaching. She shoved two fingers deep into her pussy while pressing down on her clit. She came hard. She couldn't have been masturbating for more than a minute or two. She'd never cum that fast in her life.

After a couple of minutes Abby shut off the water and stepped out of the shower. She was rarely conflicted in her actions, so this was somewhat unfamiliar territory. It was impossible to deny the attraction she felt for her brother: His cock; his Adonis-like body; she could feel heat building again. But this was her brother. It was a line she shouldn't, couldn't cross.

If she could just make it through the vacation without crossing the line, she would return to college, and then the hold the island had on her, along with the insane sexual attraction she was feeling for her brother, would surely dissipate.

Perhaps she and her brother could have a talk and sort it out, but not right now, she didn't want to deal. She needed some food, some sun, and a bit of space from Michael. She stepped out of the bathroom hoping her brother would still be asleep, but he was awake, still in bed propped up on his elbows. Why did he have to look so good?

Michael involuntarily looked his sister up and down, "Hi."

Abby was aware of his roaming eyes, as well as his nakedness beneath the sheet, "Hi, I'm gonna head down to breakfast. See you down there?"

"Yeah. I just need to take a shower."

"Okay, you go do that. I'll see you later."

Why did Michael feel disappointed when his sister left? What was he hoping for? As for Abby, she couldn't help but notice how her heartrate quickened and she flushed at the site of her brother in bed.

Abby was on her second plate of food (she was ravenous), by the time Michael got to breakfast. He mumbled a, "Hello" to his parents and headed to the buffet.

Throughout breakfast Abby tried to avoid eye contact with her brother, but whenever she was sure he wasn't looking, she would steal a glance at him. And when Abby's focus was elsewhere, she could feel Michael's eyes on him. The few times they did make eye contact, it felt like an electric jolt.

Things were no better after breakfast. Abby and Michael went to the pool, while their mom went to look into a yoga class for her and Abby, and their dad investigated scuba diving. Abby had read the same page of her paperback for the fifth time, before she gave up on her book. Eyes hidden behind her sunglasses, she peeked over at Michael. He seemed to be looking at her, but she couldn't be sure because of his own sunglasses.

Abby got in the pool and swam laps. A varsity swimmer in high school, she soon found a rhythm. Focusing on her breath and her stroke, she eventually cleared her head. But 20 minutes later, when she stepped out of the pool, she could feel her brother's eyes on her. And she didn't dislike that notion that she might be as much of a distraction for him, as he was for her.

"Your book's upside down," she said to him as she lay back down on the lounge chair next to his.

Michael hesitated; looked down at the book in his hand, "No it's not."

"But you had to check, which means your eyes were elsewhere."

Michael took off his glasses and stared at his sister, "So what if they were?"

"Knock it off Michael. You're my brother."

"I can't stop thinking about you. Not after last night."

"You're going to have to."

"Do you think I want to feel this way? Do you think I want to feel like my own sister is the hottest girl I've ever seen in my life?"

Michael's admission sent a shiver through Abby's body. "It's this island, Mikey. And that stone."

"It's not just the island, Abby." Michael wavered. He looked around, the pool area was nearly empty; nobody was paying them any mind. "I felt like this before we got here."

"What?!?"

"Please don't make a big deal out of it. I guess, I've just sort of, you know... noticed you. The last week, since you've been home from school. When I've been around you... I've felt something. I just don't think I fully realized it. But now..." Michael's eyes ranged over Abby's body, "I look at you, and it practically hurts. That's how bad I want you."

"Fuck, Mikey."

"And you feel it too. I know you do."

"It doesn't matter. We can't."

"What about just on this island?"

"I don't think that's a good idea."

"I can't get over how you looked last night. Your body, the way you looked at me..." Michael swallowed, "You tasted me, Abby."

Abby was feeling flush. She knew she was soaking wet. Michael pressed on, "You liked it, Abby. Why won't you just say it?"

"What difference does it make?"

"Because, I'm going crazy, and I just want to know that I'm not alone in how I'm feeling."

"You're not alone in how you feel."

If she were in private right now, Abby would surrender completely. The fact that they were in public was the one thing that was keeping her and her brother from crossing a line that could not be uncrossed.

Michael had a towel draped over his midsection, "I'm so fucking hard right now, Abby."

A soft, involuntary groan escaped Abby's lips.

"I want you so bad."

"I want you too."

Abby heard a voice from over her shoulder, "What do you want?"

Abby and Michael turned to see their mother looking at them, oblivious to their conversation.

"Lunch. I'm pretty hungry, I could go for something to eat."

Sue grabbed her daughter's hand and pulled her up, "You don't have time for that. Our yoga class starts in 10 minutes. You need to run up to your bungalow and change."

Sue watched her daughter depart then turned back to her son, "Honey, do you need sunblock? I'm happy to rub some on."

Michael felt his cock twitch, "I'm good, mom!"

"Are you sure? I don't want you to get a burn."

"Mom, please, I'm fine!"

"Suit yourself, sweety. See you later."

Michael watched his mom leave. Having seen her fully nude the night before, he was looking at her in a whole new light. His body loved every inch of what he saw, but his brain could not process these new feelings towards his mom. As for his sister, he was already in over his head. If she wanted to do something, he was all in. Damn the consequences, damn the sin.

------------------------------------------------------------------------------------

No, yoga did not put Abby in a Zen state. Thoughts of her brother, and what she wanted to do to him seemed to flitter in and out with every passing moment. In addition to that, watching her mother as they moved through vinyasa was having the oddest effect on her: It was making her horny. Perhaps it was from seeing her last night, and that time a year ago, when she full on saw her mom blow her dad, but she was picturing her mom in various lewd sex acts, and it was turning her on.

Abby had no qualms admitting that her mom was still a stunningly beautiful woman. Abby had never really contemplated sex with another woman beyond the occasional fleeting thought. She had been hit on by plenty of women in college, but never felt inclined to dance that dance. But now watching her mother, she wondered what it might feel like. Specifically, she wondered what it might feel like to have sex with her mother. Her mother, who a few feet away, was coated in a sheen of sweat, due to the tropical heat and physical exertion. Her glistening skin, her hard nipples outlined against her sports bra, her lean strong arms, the slope of her neck, were all contributing to some very dirty thoughts.

When the class was finally over, her mother turned to Abby, "I want to jump right into the ocean. Should we go change and meet down there?"

"Sure."

"You okay, Abby? You seem a little off."

"Just a little hot from the yoga."

"You need to hydrate, darling."

"I will when I get to my room."

Abby followed her mom up the narrow path towards their bungalows, watching her ass sway with each step she took. Abby felt unsteady and feverish with lust. Sue got to the entrance of her bungalow and turned back to her daughter, "Do you want to meet me here, or should we just meet on the beach?"

"The beach, I need a second or two."

"You sure you're okay, Abby?"

"Yeah mom, promise."

"Okay, see you down there."

Sue headed into her bungalow and Abby continued up to hers. Once inside she poured herself a glass of water and drank it down. She thought about masturbating; it wouldn't take her long. But she wasn't sure if it would tamp out her lust so much as fan the flames. She decided to change into a bathing suit and head down to meet her mom. Perhaps a swim and a normal hang with her mom would balance her out a bit.

She laid out a bikini on her bed and slipped out of her clothes. She caught sight of her reflection in the mirror and noticed the fullness to her breasts. Maybe she was imagining things, but they definitely seemed slightly bigger than usual. Either way, her flawless image reflecting back at her was something to behold, and something she had gratitude towards.

She picked up her bikini bottoms and as she bent down to slip it on, the front door opened. And Michael walked in.

"Abby, sorry!"

"Shut the door, Mikey."

Michael closed the door and turned back to face his sister, he was in his bathing suit and flip flops. Abby made no move to cover up. Michael stared at his naked sister from across the room, his dick instantly stiffening.

"What are you doing?"

"Changing, I'm supposed to meet mom at the beach."

Michael could see the lust in his sister's eyes. He kicked off his flip flops and set his book down as he walked towards Abby, stopping by the foot of his bed. The fact that Abby hadn't covered up or gotten dressed had to be a sign. He took a chance.

Michael pulled at the drawstring to his bathing suit, then let it fall to the floor. Michael's cock was full and hard. Abby stared at it. If he laid her down on the bed, she'd let him fuck her. As much as part of her would try to fight it, she knew she didn't have the will power to say no.

"Abby, I-"

"Shhh. Just don't say anything for a second."

Abby walked over to Michael. She was just a foot away from him. Both of them naked. His beautiful cock so close to her pussy. The desire was overwhelming her. Michael made the first move. A hand on her shoulder, and she all but swooned. He leaned into kiss her on the lips, at the last second, Abby turned away, so Michael's lips found her cheek. She gripped his forearm with her hand to let him know she wasn't rejecting him, but a kiss on the lips--it just felt like it would seal their fate. Too intimate. It felt like if that barrier went, everything else would fall.

Abby brushed Michael's ear with her lips, "Let me take care of you." Abby lowered her hand until it found Michael's cock. She gripped it's thickness. Felt it's warmth, and how it pulsed in her hand.

If she could get him off, that would keep them from having sex. At least for now. It would give her some time, some time to clear her mind and figure out how to keep her lust for her brother at bay.

She just needed to get him off. Need was the right word, as she held his cock in her hand, it was a need. She so desperately wanted to get her brother off, to make him cum--it was a need.

She stroked his cock in her hand. She could feel his body trembling.

Abby, while not necessarily "loose" by her peers' standards, enjoyed sex and had a healthy attitude towards the act. At her age, with no thought to having kids, it was for the pursuit of pleasure. And getting her past partners off, seeing how they lusted after her, always brought her pleasure, but this right now, with her brother, was different. Bringing her brother pleasure, knowing that he craved her, was sending jolts of electricity through her body, that were not dissimilar to how she felt under the touch of a good lover.

Abby continued to stroke Michael as she kissed and licked his neck. Michael groaned in pleasure.

"Do you like that?" She whispered in his ear.

"Fuck. Yes."

Abby dropped to her knees. Eye-level with Michael's cock, she continued to stroke him.

She looked up at her brother, "What about this?"

"God, yes."

"Do you want me to take it in my mouth, Mikey?"

"Yes."

"Do you want your sister to suck your cock?"

"God, Abby, yes."

Abby licked the head of Michael's cock, tasting the saltiness of his precum. "Mmm. I like that."

This was more than Abby had planned for, but the look on her brother's face, and the intoxicating cock in front of her, were too much for Abby to resist. It wasn't sex, at least that's how she rationalized it in her mind, but part of her knew she was deluding herself.

She sucked Michael's cockhead into her mouth. Savored the flavor and the fullness. She continued to stroke Michael. A friend of hers had told her the key to giving a good blowjob was giving a good handjob. In her experience, that had proven to be true.

Michael's hand found its way to one of Abby's tits. He massaged her breast then gently tugged on her nipple. The pleasure elicited a moan from Abby. She took more of his cock into her mouth, bobbed her head up and down and continued to rhythmically pump with her hand.

"Jesus, Abby, I'm close."

Abby removed his cock from her mouth as she continued to pump him, she was on fire. She knew her pussy was practically leaking.

"Are you gonna cum for me, Mikey?"

"Yes."

"I want you to cum in my mouth and on my face."

"Oh God!"

"I want it all over me. I want your cum so bad."

Abby sucked Michael's cock. She knew he was close. And she loved it. She loved his cock in her mouth. Blowjobs were not something she generally liked doing, she knew guys liked it, and that brought a degree of pleasure, but the act itself didn't generally do much for her, but this was incredible. The more she sucked on Michael, the more wanton she felt, and the more she could feel her own pleasure building. She could feel her vagina tightening and starting to pulse.

"Please, Mikey, I need it, I need your cum!"

"I'm gonna cum, I'm gonna cum!"

Abby pressed a finger against the base of Michael's scrotum as he shot the first load of cum into Abby's throat. When it hit her tongue and the back of her throat, Abby came. She'd never cum without some sort of vaginal or clitoral stimulation before, she didn't even think it was possible, but this orgasm was hitting her hard. A second rope of cum went down Abby's throat, and then she pulled Michael's cock out of her mouth, and aimed it at her face. She stared up at him, as a rope of semen coated her lips and chin.

"Cum all over me, Mikey!"

Abby thrust two fingers into her pussy, intensifying her own orgasm, as Mikey shot rope after rope onto Abby's face. It dripped down her neck and chin.

Abby bend down and brought a nipple to her lips and sucked the cum off of it.

"Yum."

Abby took Michael's cock back into her mouth to suck it clean.

"Jesus, Abby. That was..."

"Good?" Abby smiled and stood up.

Michael impulsively, pulled Abby in close to him, "I just have to..."

Michael slide a finger into Abby's pussy. She shuddered, "Ooooh..."

"I have to feel you, Abby. Is this okay?"

Abby nodded. She gripped onto Michael for support, "Keep doing that, Mikey. Right there."

Michael got a rhythm going with his finger, as Abby rubbed her clit with her own finger.

"You're so wet, Abby. You feel so good."

"Don't stop. You're gonna make me cum. Oh... Oh... Oh God."

Michael pulled on one of Abby's tits with his free hand, and thrust a second finger in her dripping pussy just as an orgasm rocked Abby's body. "Oh, fuck, I'm cumming, Mikey! Oh God!!! Fuck! Oh fuck, I'm cumming!"

Michael could feel Abby's vagina spasming around his fingers. He could feel his cock, which had started to go down, stiffen. As Abby's orgasm subsided, he slowed his pace, then at Abby's urging, withdrew his fingers.

Abby looked at her brother, flush and somewhat awestruck, "Wow. That was..."

"Good?"

"Yeah."

They stood in silence for a moment, just staring at each other. Finally, Abby went onto her tippy toes and kissed her brother on the cheek. "I need to shower super quickly and meet mom at the beach." Abby kissed her brother on the cheek one last time and went into the bathroom.

Michael sat on his bed. His dick still hard. He felt guilty, but he knew his sexual feelings for his sister were not disappearing anytime soon, and whatever she would willingly give him, he would gladly take.
