Irresistible

Authors note: Thanks to roftltheory for review and suggestions on this work. One comment was that the sex scenes were vanilla, I chose to leave them as is, because that fits with how I see this couple in my head.

Chapter 1

Betty and Joan were always close sisters, they embraced the twin life fully, doing everything together. They even got married in a double wedding. Their parents insisted on giving them part of the family land to build houses and raise families, so along with their husbands, they also became neighbors. When they became pregnant, their family and friends joked that they would give birth on the same day. That did not happen, but they both did give birth in January.

Doug and Lila were born just fifteen days apart, with Doug arriving first, two weeks before his cousin Lila, he often filled the role of big brother to her little sister. Being cousins, and neighbors, living on the outskirts of town, they were naturally best friends. It was at least six years before any other siblings followed, Leaving Doug and Lila the oldest and the closest. They become inseparable, spending their days exploring and playing in the woods that surround the farm.

As they sat together in the den in Lila's house, shortly after her eighteenth birthday, studying as usual, things began to change when Lila surprised Doug by kissing him on the lips. Being as close as they were, a kiss was not uncommon, but they had never kissed on the lips before. Doug looked surprised but decided to kiss her back. This time her tongue teased his lips, and he opened his mouth to receive her. Her tongue touched the tip of his, tempting it, as if challenging it to a duel. The kiss brought desires that he had not known of to the forefront of his mind. It sparked a change in their relationship from childhood friendship to something deeper and more forbidden. The kiss seemed to go on for several minutes until Lila's mother Joan, called them for dinner. Sharing goofy grins, Lila headed for the dining room, and Doug headed home. That night, for the first time Doug saw Lila not just as his cousin, little sister, and best friend, but as a beautiful, desirable woman.

As Doug fell asleep that night, the kiss lingered in his memory, churning up new fantasies. The sweet taste of her lips clung to the edges of his mouth, the feel of her tongue lightly licking his lips still lingered in his senses, the heat as their tongues wrapped around each other left him wondering what would happen next now that Lila had now become a focus of his thoughts and fantasies. He lay in bed and relieved the sexual tension within him while she occupied his mind.

Lila kept the kiss in the front of her mind as well that night. She knew she had to make the first move; Doug would be too worried about their parents finding out. Touching her lips to feel the warmth there, anticipating more romance to follow. She runs her hands over her breasts, imagining it was Doug's hands, then let one hand drift down into panties to feel the heat and moisture hidden within while still thinking of Doug.

The innocent study sessions were over, they still met to study, but now there was a growing passion between them that pervaded every look and action. Every glance was a longing look, every time they touched, they felt sparks between them. Exploring the woods became walks holding hands and make out sessions. Doug and Lila took great pains to hide their budding love affair from their parents, who they were sure would not approve. They were careful, but they were two teenagers in love.

Doug asked Lila to go to the movies with him on Valentines Day. Going to the movies together was nothing new, but Valentines Day was. The couple had never celebrated the holiday, and their parents realized what was going on immediately. The movie was some random romance movie that Lila felt would lead to more romance between she and Doug. They did not see much of the movie because they were too busy kissing and running their hands over each other. After the movie, they drove to the local make out spot and indulged in their first heavy petting session, their eager hands exploring their bodies as if touch alone could sustain them. While kissing, Doug tried to get his hand inside Lila's blouse until she started unbuttoning it for him and asking him take off his shirt as well. Leaving her blouse open, she undid her bra, but left it on, raising the cups above her breasts. This was their first time they had gotten to touch each other skin to skin, everything before had always been rushed, and over the clothes.

Doug began exploring Lila's chest like he had discovered a new playground. He cupped and squeezed her breasts, ran his fingers over her nipples, tweaking them lightly. He loved how they felt. Doug was listening to Lila's breathing and moans, learning what she enjoyed and what did not.

While at the moment, Doug seemed satisfied with her tits, Lila knew she wanted more, and asked Doug to open his pants so she could hold his member in her hand. Lila began exploring his penis with her hand, running her fingers over the head, feeling the slippery precum, sliding her fingers down his shaft to his testicles, holding and weighing his balls carefully. Lila knew he was going to cum, and it was going to make a mess, so she stopped long enough to pull off her panties, wrap them around his penis and hoped the gusset could contain it.

Doug, realizing Lila's panties were gone, took that as a sign to begin exploring her crotch, he slid one hand down to her groin and used his fingers to explore her pussy folds, being careful to avoid hurting her. He had never touched a woman here before and was unfamiliar with how much pressure he could use.

The thought of where his hand was, and what he was touching, added to Lila's stroking pushed Doug over the edge. Doug came, overflowing Lila's panties and covering her fingers with his semen. Lila did not cum this time, but she enjoyed the play session very much and was looking forward to future encounters. It was getting late, and they felt they had to head home. Putting their clothes back in place, including putting on her cum covered panties, they headed home.

The first sign of trouble came when Doug and Lila pulled into the driveway that led to their side-by-side homes, they could see all four of their parents waiting on the porches. The yelling started as soon as the car stopped. Their parents seem to fly off the porches carried by the sound of their screaming voices and descended on the pair before they were even out of the car. "What do you think you are doing?" "You are first cousins for God's sake!" "When did this start?" "How far have you gone?" "Is Lila still a virgin?" "Did you use protection?" The questions came at them rapid-fire, harrying them as they climbed out of the car. Lila had burst into tears and just sat in the car seat, trying to cover her face. Doug fought his way through their parents to reach her side. He wrapped his arms around her protectively attempting to soothe her and refusing to let them be separated. Doug stood his ground and began answering the onslaught of questions thrown toward the young couple.

"We realized we were in love a couple of weeks ago, we were studying in the den at Lila's house, and we just felt like we needed to be closer." Doug started. "No, we have not gone all the way, we are both still virgins." "We don't care about being cousins, we are in love, and there is nothing wrong with that." he said defiantly.

Their fathers reacted with annoyance and disapproval towards Doug's statements and started pulling at the teenagers to separate them again. Doug and Lila were grounded and forbidden to spend time any time together, unless there was a third person with them, even for studying. However, the pair still had to go to school, and the young couple took this as their chance to talk and plan for future dates, especially the senior prom, three months away in May. Doug and Lila came up with a plan to allow them to attend prom together, they approached another couple at school and offered to pay for their tickets, if they would act as stand-in dates. The deal was that the other couple would make it look like they were going with Doug and Lila individually to the prom, but once there, they would swap to their proper partners. This would leave Doug and Lila on their own date at the prom without their parents knowing what was going on.

For the next three months, Doug and Lila pretended to have moved on from their feelings for each other and even dated other friends to throw off suspicion. As the prom approached in May, they began dating the stand-in couple to make it seem natural when they agreed to go to prom together.

Chapter 2

On the night of the prom, Lila told her parents that she was planning on attending an after party at a friend's house, and it would likely go well into the night, to avoid anyone driving sleepy, there were arrangements made to stay overnight. So, taking a bag with pajamas and a change of clothes, she and her proxy date headed to the prom. Doug told the same story to his parents before he headed out to pick up his date.

Doug's heart raced as he entered the school auditorium, now transformed into a grand ballroom for the night. He immediately scanned the room for Lila, and when he finally saw her, his breath caught in his throat. The lovely young woman standing beneath the twinkling lights, seemed to glow as if surrounded by a magical aura. As she spotted him and walked his way, he was struck speechless by her beauty. She moved toward him, her flowing gown and the twinkling lights made her look like she was gliding across the floor towards him. When she reached him, he had to blink his eyes several times to be sure what he was seeing was real.

Lila stood before him in a lime green dress form-fitted to her every curve. The strapless bodice revealed her bare shoulders and her graceful collarbone, dusted with just a touch of glitter. The ruffled skirt flowed down to her ankle with a daring slit that revealed her toned left leg with every step. Her long, normally straight brown hair was styled into gently cascading curls accented with a lime green flower pinned at her left temple. Dark green eye shadow highlighted her beautiful emerald-green eyes, her cheeks were lightly blushed, and bright red lipstick completed the look.

Doug wore a sleek black tuxedo with subtle dark green piping, his light green shirt added a splash of color, along with an emerald-green vest and matching tie. His pocket square was carefully selected to match his shirt. His hair had been styled to be shorter on the sides, and a bit longer on top, with a slight wave to the right.

They said thank you and goodbye to their stand-in dates as they traded to their respective partners. Doug could not believe how beautiful Lila looked. He had already thought she was attractive, but this was on a whole new level. Lila for her part was very delighted at how handsome Doug looked in his tuxedo. They had been friends for so long that they never had a reason to dress up in front of each other until now; this was the first time they had made and effort to impress one another.

Doug and Lila slipped into their own little world as they swayed and twirled on the dance floor. Their dancing was a subtle flirtation, teetering between appropriate and inappropriate for a high school prom. During breaks, they held hands across a table as they gazed into each other's eyes, secret smiles and whispered words of affection had them both anticipating the rest of the night together.

Throughout the night a few of the teenagers, those who knew they were cousins, cast them looks of disapproval, but most of the young adults ignored the gossip and concentrated on their own dates. The cousins never saw the looks nor heard the whispers. They knew that word would make it back to their parents, and they already had a plan in place in case that happened. An hour before the prom was scheduled to be over, Doug and Lila turned off their phones and left the dance, hand in hand, they had been careful not to tell anyone when they were leaving or where they were going.

Doug had booked an Airbnb about 20 miles from their hometown, close enough they could make it back at a reasonable time in the morning, but far enough that no one would think to look for them there. The ride to the rented room was filled with giggles, smiles, and light touches, but they knew not to get too carried away to avoid any accidents along the way.

Once they got into the room, they could not keep their hands off each other. They had been waiting and planning this moment for three months. He tucked her long, silky brown hair behind her ears and stared into her beautiful green eyes, even more dazzling with the dark green eye shadow. His touch sent a warmth throughout her entire body. As he leaned in closer, her heart started to race in anticipation, and she wetted her bright red lips. Their lips met and their tongues danced together passionately, stoking the flames of desire between them. Kissing led to groping over the clothes, and then a hasty attempt at getting undressed.

Lila had decided she wanted to wear a sexy outfit for their first time, so she stopped the groping and took her extra bag into the bathroom. Once in the bathroom, she took her off dress and hung it on the back of the door. She looked at herself in the mirror, wearing only sexy green lace panties. At 5'6" she weighed about 130 lbs.; she was proud of her body, her measurements were 36-28-34, with c cup breasts. Pulling off the panties that she had worn to the dance, she looked over her recently waxed pubic area - only a heart shaped patch of trimmed hair remained. It was the first time she'd had that done and was relieved that the redness and swelling had gone down. Out of her bag she pulled red lace boyleg panties and a matching sheer lace open cup bra. As she put on her lingerie, she again looked at herself in the mirror. The panties were high enough to cover her heart shaped bush, but not much higher, with just enough material in the back to leave her bottom exposed. The bra gave a little lift to her breasts, not that they needed it, but left them mostly bare, with just a little support from below, her nipples rested above the bra and pointed out towards the mirror. Smiling, she knew that Doug would want to make love to her.

Doug took of his jacket, vest, and pants and laid them gently aside, aware that he would have to return them the next day, as they were rented, and the better they looked, the more of his deposit he got back. He then removed the rest of his clothing and tossed the items into a nearby chair. He ran his hands over his groin, feeling the neatly trimmed pubic hair, feeling himself become excited at the thought of where this night would lead. He knew this was the first time for each of them, and the knowledge of their parents' reaction would dampen their excitement a little. Lila and he had similar senses of humor, and he had picked out a pair of boxers to lighten the mood a bit, hoping he had made the right choice, he pulled his boxers out of his bag and put them on, then waited until Lila opened the door.

Lila hesitated at the bathroom door. Doug was the man she loved, but she also knew that if they went through with this their families would be against it, and society would not accept it. Taking this final step to consummate their love would set them on a path that could mean hard times later. Was she willing to accept a life away from her family, if that was what needed to happen? She knew she trusted Doug, he had always been her protector, and she had always playfully let him believe she needed protection. She trusted him, she loved him, she could not think of life without him. Settling her mind, she opened the bathroom door and walked out, looking at Doug, she immediately burst into laughter.

Doug stood before Lila wearing only his boxer shorts, bright yellow boxers with a smiley face on them and a small black button right where the nose would be. Lila could not stop laughing at his ridiculous shorts. He heard her laughter and smiled; few things brought him as much joy as the sound of her laughter.

"You are such a goof; do you know that?" Lila managed to say while catching her breath.

"I, um, I mean... you look amazing" Doug stumbled over his words, stunned by the beautiful young woman dressed in red lace and her breasts on display in front of him.

Lila approached him saying, "Only you would have thought to make me laugh at a time like this, that is just one of the reasons I love you."

Before he could respond, Lila had leapt towards him, encircled her arms around his neck and was kissing him deeply. His first instinct was to catch her to prevent her from falling, in doing so, he lost his balance and ended up on his back across the bed with her on top of him.

"Are we really doing this?" Lila whispered; her voice was edged with hope, but also a bit of worry about how their parents would react. She looked at Doug seeking reassurance that everything would work out.

"Society and our parents have made the rules," he responded quietly, "but I will break every one of them tonight, just to spend the rest of my life with you."

Doug began rubbing his hand along her back, from bra strap to the top of her panties, when he got to her panties, he quickly moved his hand down and grabbed her ass over the panties, making her jump and let out a little giggle. On the next rub his fingers slipped into her panties and down to grasp as much of her cheek as he could and gave it a firm squeeze. He began working the lacy material down over her butt, she raised her hips to help him. Eventually her panties were around her thighs, and she stood up to allow Doug to remove them completely while she went to work on his boxers.

Once Lila's panties were on the floor with Doug's boxers, she took a moment to take hold of his penis to look it over. Even though they had helped pleasure each other before, it was dark and in bucket seats, so they never really got to see each other naked before. She tentatively started kissing and licking the circumcised head, unsure what to do.

"Honey, I have never done this before," she admitted, "You will have to tell me what feels good, and what you want."

"Baby doll, so far it is just great," he replied with a smile, "maybe take it in your mouth some more, just be careful not to bite,"

Following his suggestion, she took as much of his dick into her mouth as she could handle and continued to suck and lick at it for several minutes. As her jaw grew tired, and she accidentally let her teeth scrape along the sensitive head, Doug shivered and started ejaculating into her mouth - something neither one was prepared for. She jumped back at the surprised emission and ended up with semen covering her face and neck. Realizing she had nothing to clean up with, she grabbed Doug's boxers and wiped herself down, tasting a bit of his semen in the process. She found it not as bad as she had expected, but not enjoyable either.

After catching his breath, Doug decided to return the favor and go down on Lila. On Valentines Day, he had touched her crotch, but never got to look at it, so he took his time studying every inch of her pussy. He started rubbing the outer lips at first, they looked swollen and flushed almost completely hiding the inner lips. After a moment, he slid a finger along the valley concealing her inner lips and searched for her clit. Once he found it at the top of the crease, hidden by a little hood, he flicked it with his fingertip and caused Lila to jump. Continuing down the folds, he found the warm wet opening and slipped his finger inside her. Now that he had a good look and feel, he started licking her outer lips from bottom to top and returning to her clit while moving his finger in and out of her pussy. As Lila began moving her hips in response, he made mental notes of what pleased her. Other than using his hand to get Lila aroused in February, he had never attempted to pleasure a woman before, hearing her moan and feeling her thrusts, he was pleased that she was enjoying this. When Lila began a long, low wail, and started pushing him away, he grew concerned that he had done something wrong.
