''Kase…I'm ready.''

Kase sat back in disbelief. Her face reddened instantly as she was lost for words. She locked eyes with Yamada, who seemed equally flustered as metaphorical sprouts of greenery popped through her hair. The two sat on the bed in complete silence as the reality of the situation dawned on them. They were really going to do this? They had talked about it for a while now. It seemed like the perfect opportunity. Their status as an official couple had been truly cemented. They were living together, and it's not like they haven't had heated make-out sessions before…despite their bashful blushes.

But, this was the next step. Were they truly ready for that?

As the quietness lingered, Yamada's resolve began to evaporate. She fidgeted and turned away, unable to look Kase in the eyes as she felt her face burn up. ''I'm sorry. I should have asked if you were ready. That was rude of me to just come out and say that. I wasn't thinking. We don't have to do anything you don't want to do…''

Yamada's ramblings ceased when she felt Kase's hand clutch hers softly. She gasped and locked eyes with her girlfriend, who had closed the distance between them and cupped her face with her free hand.

''Yamada, I want to. I'm ready too.''

Snapping out of her daze, Yamada shifted on the bed, trying not to collapse over the side. ''Really?''

Kase nodded and smiled warmly at her soulmate. ''I've told you. I wanted to wait until you were ready. If you feel that the time is right…''

''Yes, it is!'' Yamada cut in excitedly. She pointed to the window. Kase glanced outside and saw a clear blue sky. Yamada continued. ''It's a beautiful day. We're alone with no distractions. Plus…I've been thinking about it.''

''You have?'' Kase gasped as steam rose from the top of her head.

Yamada nodded timidly. ''I always wanted our first time to be perfect. I would imagine picking the time and place. It would be like those romantic movies we see. However, the more I thought about it, the more I believe that was just putting unrealistic expectations on you. It might not be perfect. We might fumble with a few things. But, that's fine. As long as it's with you, I'm happy.''

Seeing Yamada's beaming smile almost drove Kase to tears of joy. She had no clue that her girlfriend had thought this long and hard about their first time. Kase had dreams and nightmares about this moment. Despite the confident cool-girl persona that many thrust upon her, Kase was just as inexperienced when it came to sex as Yamada was. Kase enjoyed the kisses. She loved the delicate touches. She longed to do more with this beautiful, wonderful woman. But, she never pushed Yamada into doing anything too overwhelming. It also didn't help that Kase was unique when it came to most women.

Being born with a penis left her anxious throughout most of her life. She feared that no girl would want to be with her. A few stares from some of the girls on her track team didn't help with her confidence. Yamada wasn't like that. She loved Kase inside and out. The only hiccup was that school trip to Okinawa when the two of them bumped into each other in the changing room and the bulge in Kase's boxer shorts was impossible to miss. Kase spent the rest of that day apologizing profusely to Yamada. Her girlfriend would constantly assure her that it was fine, though her bright red cheeks and trembling legs begged to differ. The first time caught Yamada off-guard. Since then, Kase had grown more comfortable showing more of herself to her girlfriend. Yamada had seen her in boxers multiple times now. However, other than some brief glimpses when she got changed, Yamada hadn't seen Kase completely naked yet.

Today, that was going to change.

Kase gulped nervously before breaking out into a bright smile. ''I feel the same way. This is a first for both of us. So, if at any point you want to stop, or if it gets too uncomfortable, tell me straight away and I'll…''

''Kase, I love you. I want to be with you.''

Kase nodded before something crossed her mind. ''Oh, I don't have any protection!''

Yamada's blushes returned in full force as she reached toward the bedside cabinet. Her hand was trembling as she retrieved something from it. Kase watched on with intrigue before her eyes bulged as she recognized the item in Yamada's hand as a packet of condoms.

''I…uh…I picked some up…just in case we…you know…'' Yamada stammered.

The longer Kase stared at the packet, the deeper it struck the athlete that this was happening. She was going to make love with Yui Yamada. Her heart pounded against her chest. A tense throbbing ached between her legs. All the while, she couldn't stop smiling, even as Yamada was still trying to explain how she bought the condoms whilst abundantly sweating.

Kase took the condoms from Yamada's hand and set them down on the bed. Her touch was soft and calming. Immediately, Yamada stopped stuttering and remained quiet as she watched Kase walk over to the bedroom down before locking it. She then pulled the curtain across, leaving enough room for sunlight to illuminate the room while giving them the privacy that they craved. Yamada couldn't breathe as Kase returned to the bed and cupped her hot face once more. The taller girl's lip curled upward into a delightful smile. Yamada's heart was still racing. But, she felt more at ease with Kase being so understanding and patient with her.

How did she get so lucky?

Kase asked herself the same question when thinking about being with Yamada.

Yamada's eyes were shining with love and devotion. Kase pulled her forward for a tender kiss. The sound of their soft moans filled the bedroom. In Yamada's mind, she could see bubbles and flower petals floating around their heads. Tranquil and warm. No matter how many times she shared a kiss with her soulmate, it felt just as exhilarating as the previous embrace. Nothing could compare to the feeling of Kase's lips against hers. The seconds shifted into minutes and their kisses became more passionate. They knew that if they were going to go all the way, there was no need to hold back. Still, Kase was careful not to force herself onto Yamada. She was taller and stronger than her girlfriend. However, Yamada's patience dwindled more quickly. She wrapped her arms around Kase's body and pulled her down onto the bed so that she was pinned underneath the athlete. Their tongues clashed, sending sparks erupting throughout their bodies. Once she knew that it was okay to do so, Kase's tongue entered Yamada's mouth, eliciting more sweet moans from her girlfriend.

Their seemingly endless make-out session was romantic and sensual. Yamada gripped the back of Kase's neck, refusing to let her go. She felt Kase's hand move down to her waist, sliding underneath her shirt so that she could stroke her skin. Fireworks. That was the best comparison to make when Kase touched her. The longer they kissed, the higher their deeper desires climbed. When they separated from the kiss to catch their breath, Kase tilted her head and started to pepper faint kisses and licks along Yamada's neck.

The sensation caused Yamada to mewl and squirm. ''Kase…''

By now, they were grinding against each other. Yamada couldn't contain her excitement as she felt something hard pressing against her thigh. Her mind raced as she knew exactly what was rubbing against her. She couldn't contain her moan as she bucked her hips desperately. She wished that they had removed their clothes beforehand. The tension was becoming too much for her to bear.

''Kase-san, please…'' Yamada moaned.

''What do you need?'' Kase purred as she nibbled her girlfriend's neck. It wasn't enough to hurt her, but there was an attempt to leave a mark behind.

''Undress me.''

Kase's nerves returned. She continued to play the role of the top, but she was trembling. She pulled away and looked down at Yamada as she lay sprawled on the bed, flustered and breathing heavily. Kase spotted a faint hickey where she had just sucked on her neck. The sight drove her mad. Her dick was pulsating madly. But, she ignored it. Yamada's needs came first.

Yamada always came first.

Despite her hands shaking, Kase slowly started to undress her girlfriend. She undid her blouse, one agonizingly frustrating button at a time, before pulling it up to reveal Yamada's bra. Seeing Yamada's creamy skin and flat stomach made Kase's throat hitch. It didn't help that the girl's chest was rising and falling with every sharp breath. Kase's mind went blank as she tried to remain grounded and continue with Yamada's request to strip her. She loosened Yamada's skirt and eased it down her legs. Before long, the girl was left in a scandalous position wearing only her undergarments. Kase felt like she was going to faint when she noticed a faint spot of wetness at the center of Yamada's panties.

''Wow…'' Kase whispered. ''Yamada, you're so beautiful.''

More sprouts jutted out of Yamada's hair as she covered her face with her hands. ''Thank you.''

Kase smiled down at her. She could see how nervous Yamada was. Kase wasn't going to let her nerves rub off on her girlfriend. She grabbed Yamada's hands and forced them away from her face so that they could stare into each other's eyes. After locking her grip around Yamada's wrists, she restrained them above the girl's head and leaned down so that they could share another kiss. Yamada melted and felt nothing but warmth and comfort.

''Do you want me to keep going?'' Kase asked.

Yamada nodded and lifted her body so that Kase could reach underneath and unhook her bra. It came undone and toppled off Yamada's body. Kase's eyes widened and she nearly choked on her tongue as she stared at Yamada's chest.

''I'm sorry if they're not as big as you thought…'' Yamada whimpered.

No! Kase refused to accept that kind of self-doubt from her girlfriend. Her eyes glazed with love and lust as she immediately started to play with Yamada's small breasts, earning more moans of approval.

''You're you, Yui Yamada,'' Kase said. Her voice was etched with softness, yet carried a husky tone that sent Yamada spiralling into a storm of ecstasy. ''I love you as you are.''

''T-Tomoka…''

Hearing her girlfriend call her by her first name ignited something within Kase. She attached her lips around Yamada's left nipple and sucked on it, causing her girlfriend to scream with pleasure. Kase's tongue swirled around the erected bud, flicking it occasionally. After lavishing it, Kase proceeded to give Yamada's right breast the same loving treatment. Yamada felt her chest wet from Kase's kisses. Her legs jerked as she felt a flood of wetness rush between her legs. She had never been this aroused before. She didn't want this feeling to stop. She cried out for more as Kase continued to kiss further down her abdomen before stopping just above her crotch area. Kase didn't hesitate. Her newfound drive to prove that she loved Yamada's body spurred her into action. Even when she saw Yamada's pussy for the first time, soaked with excitement, she didn't stop.

''So beautiful.''

Kase's voice was faint, but Yamada heard. Her cheeks lit up like candles as she squealed in happiness. Yamada's moans then transformed into screams when she felt Kase's tongue licking her pussy, lapping up her wetness and eating her out eagerly. Yamada's legs hooked onto Kase's shoulders as she flickered her tongue up and down, gradually shifting into circular motions around her clit. Sparks darted over Yamada's body, making her buck in response to the oral pleasure she was receiving from Kase.

''Kase-san! More! More!'' Yamada cried out, reaching down to grip Kase's hair and push her down until her mouth was on her pussy and she felt her tongue thrust inside of her.

Every so often, Kase would change the pace. At first, she would lick constantly and quickly before slowly sliding her tongue up and down, then from side to side, all to bring her girlfriend to the highest of highs. Yamada threw her head back and screamed. Shockwaves. She couldn't think. Her mind went blank as all she could think about was Kase's tongue inside of her. Her soulmate slurped the juices flowing from her pussy. It didn't take long for Yamada to soar over the edge.

''Kase! I think I'm about to…''

She didn't have time to finish her sentence as Kase sucked on her clit and teased her entrance with her fingers. The unexpected feeling of her fingers probing her made Yamada's back arch and her toes curl. The sound of Yamada's screams sent shivers down Kase's spine. Her head was practically crushed as Yamada locked her legs around her. Kase didn't mind in the slightest.

When Yamada came, Kase felt it. A gush of wetness coated her chin and filled her mouth. The taste of Yamada's wetness was not only addicting, but it was also overwhelming. The aching in her boxers had already been at a fever pitch. However, bringing her girlfriend to a mind-blowing orgasm was the final straw for Kase. She grunted as she continued to suck Yamada's pussy, and came in her boxers. Her cock throbbed intensely as threads of cum stained her underwear. This was the first time that Kase had cum without touching herself. But, that was the power of Yui Yamada.

Yamada collapsed onto the bed, exhausted and panting heavily. Her body trembled as Kase moved into a sitting position and gawked at her. Yamada squeaked when she saw that her girlfriend's face was utterly drenched. ''I'm sorry. I've never…that was more than…I didn't mean…''

''What are you apologizing for?'' Kase laughed as she rubbed her mouth with the back of her hand. ''That was the reaction I was aiming for.''

For a brief moment, all Yamada could see was Kase. The bedroom dissolved around them as cherry blossoms fluttered around Kase's body. She was the most beautiful person in the world. Yamada smiled at her. Then, her eyes were drawn to the prominent bulge trying to break out of Kase's pants. She could almost feel the strain.

When Kase noticed that Yamada was gawking at the tent in her pants, her body quaked with apprehension. She knew what came next, but she'd be lying if she said that she wasn't unsure. Would Yamada be okay with seeing her nude without any obstructions? Years of edginess around her body threatened to chain her down. But, when she looked into Yamada's eyes, she saw complete and utter love. It was the boost that she needed. Without a word, she began to strip. Removing her shirt and bra was the easy part. Yamada's eyes sparkled as she gazed at Kase's boobs. After a few seconds of hesitation, Kase quickly pulled her pants down. An audible gasp escaped from Yamada as Kase's cock sprang free. There was a sigh of relief from Kase as her shaft was no longer restricted in a tight space. Now, she waited for Yamada's response.

Her girlfriend was silent as she admired the hard length. She was blushing furiously. That was to be expected. But, Yamada didn't baulk at the sight.

''So cute…''

Kase didn't know whether to laugh or cry. She hadn't thought of her dick being cute, and she wasn't expecting Yamada to think that, especially with how her face was enveloped in her cock's shadow due to its immense size and thickness. Yamada also noticed that the shaft was wet, and a thread of cum was dripping from the tip.

''Did you…'' Yamada was too shy to finish the sentence, but Kase understood what she was implying.

''Yeah, it happened when I was going down on you. Sorry, if it looks weird…''

No! Yamada refused to accept that kind of negativity from her girlfriend. Her eyes glazed with love and lust as she immediately grabbed Kase's cock, tried to curl her fingers around the girth and brought her mouth around the head of the sensitive shaft, earning a shocked moan from her girlfriend.

''Yamada?''

Kase watched as her girlfriend bobbed her head up and down, sucking on her cock as she tried to take as much as she could into her mouth. She felt Yamada's tongue licking around her, cleaning the mess she had made as the tip brushed against the back of her throat. Yamada gagged on it and pulled away quickly. She couldn't even take half of Kase's dick without choking.

''Yamada, are you okay?'' Kase asked, coming closer to cup her face.

Yamada smiled. ''Sorry, I guess I got carried away. I thought I could do it.''

Kase could hear the disappointment in her voice. ''Don't worry, we can try again another time.''

''But, I wanted to repay you after you did the same for me.''

''Don't ever feel like you have to do something for me just to repay me. I was happy to do that for you. As I said, we can try that another time. And we'll go slow. For now, there's something else I want to do.''

It was clear what Kase was suggesting. Yamada felt the same way. As much as she wanted to try and attempt to give her girlfriend oral satisfaction, she felt that now was not the time. She'd get another chance. Right now, all she wanted was to feel Kase inside of her. Yamada nodded and laid back on the bed, spreading her legs as Kase positioned herself. She grabbed the condom packet beside her and took one. She fumbled nervously with it as it enveloped her long shaft. Yamada wondered if it would fit. They were made to take all sizes but did they count for how enormous Kase would be? Yamada smiled once again.

Kase was wonderful and beautiful.

This moment was wonderful and beautiful.

At last, Kase leaned in and pressed the tip of her wrapped cock against Yamada's entrance. ''Are you ready?''

''Yes,'' Yamada replied.

Slowly, Kase thrust her hips and pushed inside Yamada's pussy. She took as much time as was needed to ensure that Yamada wasn't hurt by her size. She felt her clench tightly around her shaft as Yamada purred and wrapped her arms around Kase's body to hold her. Resisting the overwhelming desire to move quicker, Kase waited until she was certain that Yamada was comfortable. Once they had settled, Kase found a tempo, almost pulling out before pushing back inside. Yamada whined loudly and clawed down Kase's back as she felt herself being stretched. Despite the flashes of pain that came from Kase entering her for the first time, she wouldn't trade this sensation for the world. Kase's massive size didn't hurt as much as she feared because of how caring her girlfriend was. She could tell that Kase was holding back.

''Please, Kase!'' Yamada moaned. ''Go faster!''

Those were the words that Kase craved to hear. She thrust her hips, driving her entire cock deep inside Yamada. She started to move at a growing pace, grunting Yamada's name repeatedly as her walls tightened around her cock. The bed started to move as Kase upped the intensity of her thrusts. She felt Yamada buck against her. This was a moment that she would always treasure.

''Faster! Faster!'' Yamada continued to cry out.

Kase was more than happy to oblige with her girlfriend's request. She couldn't be stopped. She held nothing back. They weren't just making love…they were fucking. All of the shyness and hesitation between them were gone. Now, nothing mattered more than bringing the other person to peak pleasure. Between thrusts, Kase felt more wetness hitting her thigh and engulfing her cock. Yamada was brought to ecstasy over and over again as Kase's relentless thrusting continued. Kase wanted to speak. She wanted to proclaim her love for Yamada as she felt herself getting closer to her climax. But, her voice was too weak. So, she resorted to kissing Yamada. The passion and love behind the kiss brought Yamada to tears of joy. Kase's body jerked as she thrust forward and came hard.

While Yamada knew that the condom was needed, she one day hoped that she would be able to feel Kase cum inside of her. The thought of being filled to the brim by her girlfriend made her heart swell.

The couple collapsed onto the bed in a heap. Their bodies were trembling as they panted heavily and turned to gaze into the other person's eyes. They smiled at each other.

''Was I good?''

Yamada was shocked to hear such a question from Kase; doubly so with it being coated with doubt and worry. She rolled onto her girlfriend and kissed her once more, smiling against her lips. ''Yes, you were.''
