It had been two days since Zatanna gave Josie the mission to seduce Cassie, have sex with her, and get the Amazon girl to cum inside her, all to further the goal of empowering Josie to find the dark magic user who cursed various women to become futas. Cassie Sandsmark, known as Wonder Girl to the world at large, is like her mentor, Diana Prince, known as Wonder Woman. Both are Amazons and daughters of the Greek god Zeus. She was gifted with the same powers as Diana, and was likewise very beautiful with a stunning hourglass figure, a plump chest and heart-shaped ass, though that didn't diminish her muscular physique. In a few years time, she would give even Wonder Woman a run for her money. Wonder Girl had blue eyes and long blonde hair with unkempt bangs, kept in place with a black headband. She wore a black sleeveless top with two stylized golden W's on it, which resembled the W's that Wonder Woman wore across her camisole. She wore red pants with two white stripes on the sides, and blue shoes. Like Wonder Woman, she wears two silver bracelets and star earrings, though hers were silver instead of red, and she used a golden lasso that hangs at her waist.

While Cassie was more easy-going and energetic, when Josie was taken on as Wonder Woman's pupil, Cassie, her first student, became a little annoyed. Diana would take the both of them on missions, but their cooperation was strained at best. That was Josie's first problem: Cassie didn't like her very much. Her second was that she had no game. All of her previous lovers pretty much came onto her. Josie managed to turn her interview with Lois into something more fun, but she had no idea how to replicate that, especially with someone who didn't like her. Her only bet was Cassie being as backed up as the other futas, that she didn't masturbate and was constantly frustrated enough to take the first girl who made a move on her. To that end, Josie disguised herself and went to a costume shop, a more adult shop, to purchase a sexy version of Wonder Woman's outfit. Her plan would either work exceedingly well, or fail miserably and only make things worse. So, no pressure right?

Josie was filled with a sense of dread as she looked over the scandalous outfit she laid out on her bed. The most she hoped for was hate sex, but there was hope they could get closer at some point. Taking a deep breath, she took off her regular clothes and proceeded to slip on the sexy Wonder Woman outfit. The gold tiara went on first, then her gold bracers, all of which felt like cheap metal. The leotard had a red top part that just barely covered her chest, leaving the sides of her large breasts exposed. A strap wrapped around her neck to keep what was there in place. Her stomach was only partially covered by two wider straps that connected to the blue v-cut bottoms with white stars. The belt around her waist likewise felt cheap, and the stand-in for the lasso of truth was made of nylon. Fortunately she didn't pay much, but she was surprised Wonder Woman's outfit wasn't in higher demand to warrant higher-quality versions.

Josie spent some time in front of her mirror, looking over herself. "This really is revealing... If she doesn't like it, I'll be so humiliated." The girl muttered, blushing. The bottoms dug into her ass, showing off more than she would have liked. She still had the boots set aside to complete her wardrobe. Her back was turned to the mirror so she could properly look, and opposite the mirror was her door, which opened, allowing Wonder Girl herself to step inside. "We have a mission scheduled for tomorrow, so get-" There was no knock, as manners were apparently not a thing for frenemies. Josie and Cassie locked eyes as the automatic door closed behind the blonde heroine. The room became silent as an awkward atmosphere settled in. After a minute or two of looking the cosplayer over, Cassie cleared her throat and narrowed her eyes. "What in Hera's name are you wearing?" She began an interrogation.

Cassie stalked towards Josie and crossed her arms beneath her chest, sizing the elemental heroine up. Josie fidgeted in place and tried to collect her thoughts. This was an ideal situation, wasn't it? The two of them, alone, in a room where Josie could work whatever magic she had that seemed to get futa women to fall for her at first sight. The cosplaying girl cleared her own throat and tried to look seductive, shifting her weight to one leg and resting her hand on her hip. "Well, I thought we could ... bond, as Diana's two students." She began. Cassie raised one of her eyebrows, truly baffled. "Bond?" The demigoddess repeated. Josie smiled and nodded. "Yeah. I also have it on good authority that you have a ... sizable issue that has been bothering you." As she spoke those words, she reached between Cassie's legs and stroked her magically hidden bulge, one that already felt pretty warm and firm, betraying the Amazon's appreciation for Josie's scantily-clad body.

Cassie smirked and roughly grabbed one of Josie's breasts. "So THIS is what got you into the League, and Diana's tutelage? You just seduced her with this obscene body?" The Amazon accused her. Josie blushed and winced, biting back her voice. She failed when Cassie pinched her nipple through the thin fabric of her costume and pulled, letting a brief whine escape her mouth. She felt Cassie's shaft harden in her hand, evidence that the blonde Amazon liked what she saw and heard. She pulled off Josie's tiara and tossed it aside, then she pulled apart the straps that kept the girl's top up and pulled it down, exposing the elemental's chest. "Let's 'bond', Josie. I have to wonder what sort of moves you pulled on Diana to make you her student, when I'm clearly the superior warrior." Josie would have offered a retort, but Cassie silenced her with a fierce kiss. The girl thought her problem would be seducing Cassie, but the real problem was surviving the jealous and resentful Amazon beauty.

Cassie took a step back, pulling her lips away from Josie's. She argued with herself, that the kiss was nothing, and she would just leave Josie in a mess on her own bed and report to Diana that the elemental heroine wasn't worthy. The argument was at a standstill, since the kiss was actually nice, and she secretly wanted more. The Amazon grit her teeth and pulled Josie's costume down to her ankles and ogled the nude girl. "Hmph. The most well-rounded thing about you are these tits, right? These sexy, soft tits." The blonde girl rubbed and kneaded her chest, left almost breathless by what she saw and felt. She quickly snapped herself out of her reverie, though it didn't go unnoticed by Josie herself, who found something of a weakness in Cassie's stubborn armor. "Yours aren't half bad either. Is it the warrior's way to leave someone at a disadvantage in the bedroom?" The girl asked with a slight smirk on her fine lips.

The Amazon kept up commanding face and began to strip herself bare, though Josie could tell she wanted to get naked as quickly as possible. The glamour that hid her girlcock was undone, revealing it's impressive size and girth. She was at full mast and seemed eager to take Josie, though her mind raced with the different positions she wanted to try, all of which involved Josie on the receiving end of her lustful wrath. "There, but I think you're still at a disadvantage, Josie. Here, let me prove it." With a grin, she easily lifted the elemental into her arms and carried her to the bed. There, she was unceremoniously dropped, though she suspected it was because Cassie wanted to see her bounce. It was true of course, and Cassie made little attempt to hide it. Once she settled on the bed, the blonde girl climbed on and straddled Josie's torso between her thighs and grabbed the girl's breasts to sandwich her shaft between them.

Cassie softly moaned as she used Josie's chest to pleasure herself. They felt so pillowy soft against her rigid shaft, that she felt she could cum at any moment. It didn't help her plan to resist the urge to do so when Josie opened her mouth and licked the head of her girlcock. "Oh, you want this in your mouth? Why didn't you just ask?" She bucked her hips forward, pushing her shaft into Josie's waiting mouth. The brown-haired elemental went to work, licking and sucking on the futa girl's cock. Josie already tasted some precum seeping into her mouth, confirming her suspicions that Cassie was just as backed up as the other futas she ran into. She bat aside Cassie's hands and put her skills to work, massaging the futa girl's cock while she licked and sucked on it, coaxing a long-awaited orgasm from the frustrated girl. Of course, Cassie's pride wouldn't allow it, at least not without giving as good as she got.

The blonde amazon let Josie have her chest back, since she apparently knew how to use her supple mounds. "Are these the skills you used to seduce Diana? I think you might be more fit for a bedroom than a battlefield. Yeah, after we tire ourselves out fighting evil, you can tend to our lust." Cassie derided the girl beneath her, trying to bite back her moans. Josie only gave a playful wink and offered no other retort. Annoyed that she couldn't goad some sort of argument, but more annoyed that she felt undeniable pleasure from her rival, the blonde futa girl reached behind her and slid her hand down Josie's body, caressing her stomach and moving down to her pelvis. The brown-haired girl's breath hitched in her throat in anticipation. Trying to catch her off-guard, Cassie started to move her hips again, pushing her shaft deeper into Josie, right down the girl's throat. Of course, given her experience with well-endowed girls, the brown-haired was able to handle herself just fine, though her new partner was becoming a bit rougher than the others.

Cassie smirked as her hand reached Josie's flower and felt how hot and wet the girl had become. She began to firmly rub her hand up and down, eliciting muffled moans from the elemental girl. Cassie quickly decided to pick up her pace before she 'suffered the indignity' of having an orgasm before her rival and plunged two of her strong, yet soft and lithe, fingers into Josie. She felt the girl tighten around the two intruders, but she pressed on with her assault, using what she knew of her own private times to pleasure the girl who was doing an exceptional job of bringing her closer to an orgasm. The blonde girl couldn't contain her voice anymore. She felt her girlcock throb and pulsate, desperate to release what felt like a huge load onto Josie. Were these the skills that brought Wonder Woman herself to her knees? Fine, her mouth and breasts felt positively divine, like she was blessed by Hera herself, but to already be so close to a climax felt like a failure to Cassie.

The blonde girl found one of her rival's sweet spots and focused on it and the girl's exposed clit, working both while she felt her flower quiver, signaling that she was just as close. Josie's moans carried on as nice vibrations through Cassie's hot and hard shaft, sending tingles up her back. The Amazon focused so much on trying to get her sexy rival off that she dropped her guard and went over the edge, her body writing, racked by pleasure and ecstasy as she rode out her long-awaited orgasm. She raised her voice high as a fountain of thick fluids shot out of her girlcock and into Josie's mouth. The elementalist had little trouble swallowing everything that poured into her, though her attention was divided as she rode out her own climax. Her groans were driving Cassie wild, who promptly decided to keep moving her hips and use Josie's mouth and throat for longer than necessary, while at the same time, moving her fingers in and out of the girl's quivering slit.

After a few moments, Cassie took a deep and calming breath and pulled herself away from Josie, sitting beside the girl who managed to take the edge off of her frustrations. It felt good to have Josie beneath her, writhing in pleasure and ecstasy. Only because Cassie herself belonged on top, of course. It wasn't because Josie was kind of sexy and she felt incredibly good. The futa girl was still hard and raring to go, and she wanted to make her rival submit in some way, to prove that Cassie was the superior warrior and Diana's top student. While Josie was still recovering, Cassie used one hand to effortlessly roll the girl onto her stomach. "I'm not through with you. Not by a long shot." The Amazon declared. Josie could only grin and raise her ass in the air, swaying it from side to side. Cassie blushed, transfixed by the erotic sight. She quickly collected herself and delivered a slap to the tantalizing cheeks, which only earned pleasured moans from the girl, who did not stop her erotic display for another moment or two, something the blonde girl begrudgingly enjoyed.

Cassie stood on her knees behind Josie, her heart racing in anticipation. She reached down and rubbed her pulsing cock against her rival's wet flower, making both girls moan softly. Her mind battled between wanting to just feel good and wanting to make Josie submit. For a brief moment, both sides converged, to feel good while trying to dominate Josie, but it only admitted that it felt good to be with Josie, something she refused to do out loud. The blonde futa girl lined herself up with her rival's warm and inviting flower, briefly debating on how she wanted to set the pace. Would she go slow and work her way up to a faster pace, or should she just go fast and hard right from the start? She quickly made up her mind, deciding to quickly buck her hips forward, hilting her full girth deep inside Josie, easily reaching her womb. Their voices rang out in unison as Cassie filled her. The Amazon had never felt anything so good, the way Josie's slit coiled and tightened around her as she stretched the girl to fit her girth. "By Hera ... you're still this tight after having sex with everyone? Maybe you really are blessed." It almost sound like a compliment, and it ended with another slap to the girl's ass.

Cassie liked to see Josie's ass jiggle with each hit, and she had to admit that the elemental heroine's whines were sweet to hear. She moved her hands from the brown-haired girl's hips as she decided to go a bit harder. She grabbed Josie's wrists and held them behind the girl's back. The Amazon smirked, finding a good pace as she thrust her throbbing girlcock forward and pulled Josie back, gouging deeper than any of Josie's lovers. For a brief moment, Cassie regretted not facing Josie the other way, since she wanted to see her rival's face twist with pleasure. Of course, it would only be to mock how silly she looked. She grit her teeth again, fighting in vain against the overwhelming pleasure she felt, the same euphoria that her mentor and idol felt when she was with Josie. The elemental girl looked over her shoulder and flashed a sultry smile and wink. "I'm not -ah!- sure if the gods -mm!- blessed me, but I know two -ah!- demigoddesses who can't seem to get enough of me."

That last remark, which struck home for Cassie, set her off. "Are you sure it isn't the other way around? Maybe you want a trip to Themyscira to get gangbanged by a bunch of Amazons." Another slap sent pleasurable shudders through Josie. "I'll have to politely refuse. I wouldn't want you to get jealous, Cassie." The elemental replied in a cute tone of voice. Cassie's face turned a darker shad of red than it already was, taken aback by the blatant flirting. She couldn't think of a good enough retort. Her anger and resentment were coming apart, but she didn't dare to reveal that to her rival. Instead, she upped her efforts to make a mess of the sexy girl, bucking her hips harder and faster. She tilted her head aside, catching a glimpse of Josie's chest bouncing back and forth with each thrust. An image appeared in her mind, one where Josie was riding her, and she could look at them all she wanted. That thought was pushed aside as she felt another orgasm building up inside her. Josie tightened and trembled around her length, and her voice rang out louder. Another race to the finish ensued. The last match was a tie, but Cassie was desperate to make Josie cum first.

Cassie released one of Josie's wrists and leaned down, reaching between the girl's thighs to find her clit, which she proceeded to rub and tease. Josie's body writhed in rapture as she reached the peak of her second orgasm. Her love juices flowed out, coating Cassie's girlcock. A feeling of victory soon turned into ecstasy as the futa Amazon enjoyed her own climax. She didn't even bother debating where to release another thick load of cum, she poured it directly into the girl's flower, filling her to the brim. She leaned back and enjoyed the feeling, riding a euphoric high as she was slowly understanding what Diana liked and adored about Josie. Her body was simply made to attract and pleasure futa girls. "Haha... I made you cum first..." Cassie breathed, feeling proud of herself. Josie, as ever, put a different spin on it. She pushed herself up and leaned back against Cassie and turned to face the Amazon girl. "Aww, you wanted to make sure I got off. Thank you." She cooed.

Before Cassie could offer some snide retort, Josie pressed their lips together, a tender kiss to seal their new and fun rivalry. Josie took advantage of Cassie's surprise and grabbed the blonde girl's hands and placed them on her own chest. Cassie indulged herself for a moment, cupping Josie's supple breasts while she made out with the elemental girl. She felt herself harden again, still pinned inside Josie's flower. She quickly caught herself and pulled her lips away. "We're not dating. One time having sex doesn't mean we're a couple." She stated, her stubborn nature coming to the surface again. Josie giggled in response. "You're sending mixed messages, Cassie. It was twice, you're still inside me, and your hands are still on my tits." The brown-haired girl pointed out. Cassie decided that Josie needed more convincing about which one of them was better, and she planned to spend as much time as necessary to prove that point. It had nothing to do with how good it felt, her pride was on the line and nothing more.

Josie groaned softly as she felt Cassie's girlcock leave her. "Round three, and I'm not letting up until you admit that I'm better." The Amazon spoke into her ear, sending chills down the elementalist's back. Cassie spun her around and pinned her back onto the bed, a hungry and predatory look in her eyes. She hovered above the girl with her hands on either side of Josie's head, straddling the elemental girl's hips between her knees. Josie merely smiled at her. "You are better than me. I'm just a rookie, but you can fight on par with Wonder Woman. I just hope I can be as strong as you soon, so I can fight more bad guys and save more people." The girl confessed her dreams. This wiped Cassie's grin right off her face, and she blushed again, seeing Josie in a different light. She was cute, and adorable, and sexy, and it made Cassie want to dominate her all the more. "G-Good. You admitted it, but I'm still not done with you yet." The Amazon stammered. Josie giggled and wrapped her arms around Cassie's neck. "Oh no~ Don't make me scream again. Don't cum inside me anymore~" She joked in a tone Cassie wouldn't dare admit was cute.

The blonde Amazon girl thrust herself back into Josie, and allowed herself to moan as loud as her rival. She couldn't get enough of Josie, how good she felt, her warmth and sent, though she wanted to taste her now. She lowered herself and initiated a kiss, plunging her tongue into Josie's mouth. The elemental girl offered no resistance, hoping for that move. Clearly her plan was working, though not in a way she expected. Cassie was rougher than the other girls, but she loved it. She wrapped her legs around Cassie's back, encouraging the Amazon to keep going. Cassie pushed herself up and away from Josie's soft and sweet lips as she moved faster and harder. She wanted to see the brown-haired girl's face as she went all out. Josie cried out again, giving Cassie exactly what she wanted. Instead of coming up with any witty remarks, she found the girl all the more endearing. The sight of her large chest bouncing was also nice.

The blonde girl lowered herself again so she could indulge herself on Josie's breasts. She dragged her tongue up one of them, ending with a flick against a stiff nipple. Then she sucked on it, pulling her head back and releasing it, all to watch it bounce back into place. She continued on with the other supple mound, all while enjoying the sensual sounds Josie made. Cassie let her passions carry her, and her lips met Josie's again in a fierce kiss. She pressed their bodies closer, rubbing their bosoms together as Cassie moved. The heat and friction generated drove them both on, their voices muffled by their kissing. The Amazon girl felt another climax building up inside her, and had, by then, learned Josie's cues when she was about to have her own orgasm. There was no race to see who would cum first, she just wanted to enjoy the moment with her lovely rival.

Cassie pulled her lips away as both she and Josie climaxed in unison, raising their voices together. Zatanna had already cast a spell that would soundproof the room for her romantic encounters, so there wouldn't be an issue of getting discovered. Cassie filled Josie's depths again, pushing out the excess and soiling the girl's bed even further. With a clearer head, she wondered if she could even get Josie pregnant. That thought alone made her interested, if only for a moment. She laid on top of the girl, smothering herself Josie's cleavage as the two enjoyed a warm and intimate afterglow. The room was silent, save for their soft breathing.

After a while, Cassie pulled her softening girlcock out of Josie and laid beside the girl, with a warm, contented smile on her lips. "Fine, I suppose I am impressed with you." She finally admitted. Josie giggled and rolled onto her side, facing Cassie. "Will you admit that it was my crime-fighting prowess and not my sexual skills that got me into the Justice League?" She asked. Cassie rolled her eyes and just gave Josie a quick kiss. "Maybe. You'll have to earn that level of respect from me, and it won't be easy." The blonde girl stated with a grin. Josie giggled again and rolled Cassie onto her back, then straddled the Amazon's hips. "Don't let me off easy now~ I have been having sex with Diana pretty regularly." The elemental girl teased. Cassie saw the attempt to rile her up and smirked. "Fine, I'll be rough on you. The first student can't be easy on the second, after all."

Author's Notes: This was a fun one to write, Cassie Sandsmark takes her frustrations out on Josie over being Diana's new student. Of course, since it's Josie and another futa, sex was bound to happen. That must be Josie's real super power. Regardless, a huge thanks has to go to BraveVesperia01 for commissioning this series.
