Zia smiled at Emma's shyness but it's Ada for pushes through with impatient force. As always since they were children, Zia apologized for her while they entered the house. "No worries, Em." Her eyes explored her cousin's body taking extra time to admire the way the bikini fit her. She mentally kicked herself for eye-fucking her cousin. "Your bikini is super cute. I almost regret bringing an one piece."

Zia brushed a hand over her one-piece to ensure her nipples weren't erect from the compliment. Before she could press her luck further and flirt, she pulled a loose hair already on the verge of falling out of her loose bun. "Oh, hey! I got my hair done last weekend. What do you think about the color?" In the background, she heard her sister groan in annoyance. Zia cleared her throat as embarassment and shame returned. God, she was such an obvious people-pleaser, wasn't she?

Zia laughed nervously, averting her eyes away briefly to read the analog clock on the wall. "Never mind that... How's school going?" Not the most reviting question, but it was one she was comfortable with the most. While she wasn't the hottest (thanks to her darling fraternal twin Ada), Zia was smart and well-read. She slipped her arm around Emma's shoulder as she often seen Ada do. Over her shoulder, Ada made herself comfortable and appeared to be on social media again.

Zia listened intently as Emma recalled the latest for her in college. She squeezed her shoulder, bringing her closer. God, her cousin was so cute. Her eyes dropped to Emma's lips before she snapped out of her incestuous thoughts. "That's a lot more interesting than the study groups I lead for literature class." She glanced away from Emma to the hallway leading to the bedrooms. She wondered when her aunt would be done.

Misunderstanding the nervousness in Emma's body language, she dropped her arm yet remained close enough to touch the woman with her leg. "My bad. But, uh, yeah. Dating anyone recently?"

"I understand that," which Zia did. "My last girlfriend ended up leaving me to try to be with Ada." At the sound of her name, Ada replied with a groan, "You know I don't do sloppy seconds especially yours. Besides, she talks way too much."

Zia nodded. "It did. It stings knowing someone only wanted your sibling, but..." She pulled Emma into an embrace. "Family is better than dealing with strangers."

"Me too!" Zia exclaimed as Ada groaned; the older twin always hated moments like this 'friendship is magic'. Thought that memory only made Zia proud to hug her cousin tighter. "I wished you didn't move several cities away, but at least you have more than us country girls." She snuggled into Emma as she laughed at her partial joke. There wasn't a lot to do in their rural town.

Zia was momentarily confused by Emma's affection, but silenced the thought with a reminder that it was in her nature. There was no way Emma could ever look at her the way she looked at Ada. It was frustrating, but a girl can dream. Still, she gripped Emma's hand as if it was a lifeline, tethering her to the dream that after so many years the same affection could be returned. Being the shorter of the two, Zia leaned against Emma as they walked. Her eyes dropped to her cousin's breasts and the way her pussy lips looked puffy in her bikini bottoms. She blushed, looking away with the hope that her own arousal wasn't evident. "Hey, Ada. Mind if I use the truck later?"

Zia pouted. "Hey, not my fault I like books." She turned her eyes away from her fraternal twin to look at Emma expectedly. "Em, can you back me up on this? Liking books doesn't make you a nerd."

Zia's eyes brightened. While Emma didn't outright defend her, the woman was in agreement about their shared love of books. It was the only area Zia could have her cousin to herself without her sister's interference. Throughout the years, the women recommended their favorite authors to each other. In a way, it helped Zia fall in love with her cousin and her rich inner world. She clung to the taller girl more as she tightened her hold on her hand. "See! Em understands! A book can tell more than social media, Ada." Zia blushed at her sister's disinterested eyeroll. Ada: "Keep telling yourself that while I maintain my 11k followers."

"Yes! I read this lesbian novel set in the 1900s about two women who met during a party. Both of them were engaged to wealthy men and came from different backgrounds. Mid-way through, they discover that they're first cousins—one of the women never met her family but the other had all the records. Instead of stopping their relationship, they continued and..." Zia trailed off upon recalling the novel and the not so subtle beginnings of arousal collecting in her one-piece. She avoided eye contact with her sister and allowed herself a shy glance at Ada. Her cheeks were flushed in arousal, but they couldn't do anything. Right? Reading taboo was different from acting on it... Before Zia risked everything to test the limits, the sound of movement inside the house told them that their aunt was finally ready. "Hey, Auntie Zoe!" Zia said, her tone bright.

With a playful push of her aunt, Zia followed in step as the four women walked to the beach. Subconciously, she brought Emma's knuckles to her lips to sate her own desires for the women. Her eyes couldn't help but travel her twin's and aunt's bodies, resting on their shapely asses. It was one of the many things Zia loved about being a lesbian; women were eyecandy and everyone in her family were beautiful. But at the moment, her heart was with Emma. As they arrived, Zia laid out a towel and gestured for Emma to do the same beside her. She stuck the beach umbrella where the middle would be to create privacy. "Em, I wanted to ask you something kind of weird."

Zia strung her words together carefully. "I know we both like girls, and I know taboo stories are dumb fantasies... But hypotheically, if you could date a cousin and do all the things girlfriends could do, would you? I-I guess it could count for Ada too in this scenario. Since she's a cousin and cycles through girlfriends like they're trading cards..."

Zia deflated slightly. "O-oh yeah! Taboo is taboo for a reason." She tried to play off her disappointment at Emma's answer with her awkwardness. "S-sorry about that. I, uh... Thinking about that last book I read made me dumb, but it did turn me on a lot talking about it. Incest is like a forbidden fruit and I wonder what it's like to be Eve tempted by it." She stroked her slit underneath her swimsuit and tried to play it off like she was adjusting how it clung to her. Her eyes drift toward her aunt Zoe helping Ada put on sunscreen in a meticulous way. No, that wasn't helping Zia's horniess either.

"Yeah," Zia agreed. "It's complicated!" She could feel her blush getting worse as the summer air was beginning to feel hotter. She released a breath. "It's definitely easier to hide stuff on the farm than a beach town." Zia didn't know what she was doing, spiling her guts out. The thread was slipping further and further out of her hand. "Ada would kill me if I ever said this... D-did you know she used to use me to practice kissing? F-for years, actually... Said we looked enough the same that it wouldn't be weird and if it's family, we can keep a secret... W-we could kiss? It doesn't have to mean anything..."

Zia nodded as she hid her face in her hands. She lifted her head to see her sister helping their aunt apply sunscreen. "Yeah," she lowered her hand toward the towel then upon seeing Emma's, she inched it closely to where their pinkies touched. "We used to do it all the time when we were bored. I think Ada got off on it. I remember her face looked flushed and a wet spot on my leg from where she rubbed herself. She'd straddle my leg during makeout sessions. We never went further than that. She got her first girlfriend and never wanted to kiss after that..."

Zia allowed herself to look at Emma with equal parts love and lust in her eyes. She turned the face her, moving her hand to rest on the woman's thigh. "Y-yeah... I'll lead." At her promise, she caressed Emma's cheek and lifted on her knees slightly. She pressed her lips against hers, hesitant to do more than part her lips in case Emma didn't want their tongues intertwine. She rubbed the woman'd inner thigh yet didn't ascend further.

Zia felt emboldened that Emma didn't pull away and gave way to impulse. Her hand crept higher, caressing her inner thigh a few centimeters from the woman's heat. Realizing what she was doing, she pulled away. "Shit. S-sorry! I almost got carried away." But she wanted to get carried away. A part of her wanted to make Ada jealous that her silly crush got validation. Though, she also wanted Ada to watch her kiss a woman other than her. They haven't been intimate since high school but...what if?

Zia moved away to dig out a novel from her beach bag. "Y-yeah. Thank you for indulging my..." She trailed off, not having a word that wouldn't make things weird. As she opened the book, she felt Ada's eyes on them.

Zia felt her face burn again. If her skin got any redder, she'd faint from heat stroke. "Ada, stop," Zia whined and grumbled when her sister forced herself in the middle of her and Emma.

Zia punched Ada in the arm at her comment then glared when the woman pulled away. "Stop being a jackass. That meant nothing like all the stuff we did on the farm years ago." Noticing Emma's discomfort, she lifted Ada out of the space between them. "We're trying to read. Go find someone to mess with. Maybe you can help Aunt Zoe with her tan."

Zia sighed then, feeling her sister put her knee between her thighs. She hid her face to not react to her apply pressure against her clit. "I'm not in the mood to wrestle." A moan escaped from her sister's efforts. "Damn it, Ada. S-sorry Em..."

After some effort, Zia managed to free herself from her sister and snatched Emma's hand. "Let's go explore the boardwalk. I need a breather."

When they were far away from the beach, Zia gazed up at Emma apologetically. "H-hey. Sorry about all of that. I don't know what happened with Ada all of a sudden and I'm sorry if you felt pressured to kiss me. I don't want to turn into someone you hate or someone you find gross." She tightened her grip of their laced fingers.

Zia sighed in relief. "Nothing in public? What about in private? Sometimes?" Zia idlely played with a loose strand of hair to keep her from descending into stammers. "I...don't want to completely ignore what happened." She lowered her voice as she led Emma to the side of a building; her shyness peaking. "Em, I've liked you since we were kids and I know it's odd but all these years I've wanted your attention but you also seemed to favor Ada at times..."

"Sorry if this is putting you on the spot and if you don't want to test the waters, we don't have to."

Zia swallowed hard before she peaked around the corner. Finding no one on the boardwalk, she leaned closer to Emma. Butterflies settle in her stomach as she kissed Emma again. Her free hand ghosted up the woman's skin and rested on the small of her back. She didn't push the kiss further, allowing her cousin to set the pace.

For the quiet moment in the shadows, Zia's mind drifted to the yuri eroge that dominanted gigabytes of space on her laptop. The emotions poured into their closeness was felt by Zia, soothing the part of her that believed she didn't have a chance. Relief inspired her hand to creep lower from the small of Emma's back to laid against her bikini-covered butt. She didn't squeeze or apply pressure, wanting to test whether her cousin liked the contact before anything else.

Zia moaned in kind, her body feeling like it was set ablaze by Emma's hand cupping her breast. She leaned in more, hoping her cousin noticed how much she liked it. Emboldened, she brought her other hand to Emma's ass and massaged it gently.

Zia's chest fell hard as she looked at Emma. She could feel herself wetter than their kiss at the beach, and it had her happy that they were in swimwear. She intertwined her fingers in Emma's, relieved the woman appeared to be as excited as she was. "Okay," she responded, her voice soft. "Where to?" She allowed the woman to decide where this place would be; she believed Emma would understand the beach town best as a local. Zia was a country girl too new to this town.

Zia was surprised they reached the house quicker than they left. Part of her thought to text Ada and Aunt Zoe to bring their stuff back from the beach, but Zia didn't grab her beach bag with her phone inside. Emma didn't look like she had her phone either. The thought of informing their family about where they ran off to faded once they headed into Emma's room. Zia's heart raced as she's placed on the bed. One of her hands undoes the string ties of her cousin's bikini bottoms. "Have you had sex before?"

Zia released a shakey breath. "G-good. I never went this far with anyone before, s-so teach me."

Zia bucked her hips, seeking more of the heat of her cousin's hand. She moaned into the kiss, feeling every nerve ending on her body come alive. Her hand explored her cousin's naked body before arriving between Emma's legs. Remembering the images from her favorite yuri eroge, she rubbed Emma's pussy. The wetness her fingers collected made her shudder and fuel her nervousness at the same time.

What if Emma discovered sex with her was boring? Zia might have made out with her sister and did heavy petting in the past, but she was more of a virgin than she let on. She knew Emma would be able to tell since she's been with women in the past. God, Ada definitely was better than her. There was a reason that despite her personality girls cycled out of her room and the back of the truck often.
