Starfire could feel her skin tingle from the very air itself. The Day of Fertility was right around the corner, and she felt herself floating without even thinking about it. She was just so happy, there was joy tingling through her every cell as she licked her lips.

The Day of Fertility was one of her people’s most amazing, most wondrous holidays. A day of love and gift giving, a day to celebrate the bonds between individuals. It was like Earth’s holidays of Chrtismas, Thanksgiving, and Valentine’s Day all rolled into one!

Starfire was especially eager, because this was her first Day of Fertility with a partner. Robin was her mate since their battle with Brushogen, and she was all too eager to celebrate with him. They would make love tomorrow, and she would feel his cum filling her eager womb.

It was a well known myth of her people that to cum inside their mate on the joyful date would seal their fates together forever. Starfire knew better than to believe in the notion, but that did nothing to dissuade her.

She flew towards her boyfriend’s room, a smile on her face as she planned on asking him about his plans for tomorrow. She would give him a wonderful date and, as the earthlings said, ‘rock his world.’

Starfire’s feet floated inches off the floor as she came to Robin’s room, but something was off. Her acute senses immediately picked on something else in the air. A voice that was neither hers nor Robin’s.

It only took her a moment to realize it was Raven’s voice. The two of them were talking, she realized as she pressed her ear against the metal door.

It was odd to think Raven was inside her boyfriend’s room, and even more odd when she heard the two talking. Starfire didn’t mind, though. They were all friends, and if Raven needed to speak to their leader, so be it.

Part of her even considered inviting her to celebrate her people’s holiday tomorrow, but that all stopped when she heard clearly what they were saying.

“A-are you sure about this, Robin?”

“Of course I’m sure, Raven… I want this.”

“What about Starfire…?”

“Honestly? I want you more. I love you.”

Love? Starfire’s heart pounded in her chest, hitting the inside of her hips like a gong as she took deep, shaky breaths. She placed her hand on the door, pulling it slightly so she could peek into her boyfriend’s room.

There he was with her close female friend. They sat on the bed, smiling at each other as Robin placed a hand on her cheek, pulling her closer.

“I… I love you too, Robin. I always have,” Raven replied, and the two kissed as Starfire felt her heart shatter in her chest.

They kissed, and they pressed against one another. Starfire found it hard to breathe as she was dealt a blow more powerful than most villains they fought. She fell to the ground, body hitting the floor, but the two were too lost in each other.

Robin was pulling Raven’s leotard off of her body as Starfire felt tears pool in the corners of her eyes. She stood up, shaking as she began to move. She ran, she ran as quickly as she could as Raven and Robin’s quiet moans filled his room.

Starfire ran as quickly as she could to her room. She wiped the tears from her eyes as reached her room. She opened the door, only to hear something strange. More moaning?

For a moment, she thought her mind was playing tricks on her. That was the only explanation for still hearing those accursed sounds, but no. It was something else, or rather, someone else.

The sounds of moaning were just like the ones from Robin’s room, but they were louder. Starfire blinked, before glancing at the room next to hers. Terra’s room? She walked closer, finding the door slightly agape as she peeked inside.

It was like some kind of twisted reflection of Robin’s room. There Beast Boy was, with his partner Terra, but what they were doing would make anyone blush, even the flirtatious Starfire.

She watched as her friend Beast Boy fucked Terra like she was a dog, leaving her on all four as he pounded away at her womanhood, filling it with his cock as he pulled on her hair. Terra faced the door, but she didn’t even seem to notice Starfire peeking inside.

Terra’s eyes were dizzy, almost cross-eyed as she smiled from the way her boyfriend made love to her. The blond was almost screaming in pleasure, lifting a hand up to cover her mouth as drool trickled down her lip.

Her other arm seemed to give out as Beast Boy continued to fuck her, and Terra hung limply as her boyfriend held her up by her hair.

It was so savage. So animalistic. Starfire covered her purple lips as Terra’s tits swayed back and forth from the harsh fucking. Beast Boy was grunting into her ear like a… a beast. He bit and sucked on her neck, making her moan louder as Starfire licked her plump lips.

She wanted to be treated like that. She wanted to be fucked like that, impaled on his cock like a beast.

Her finger brushed against her pussy, sliding into the wet entrance as she watched the two go at it. Beast Boy continued to fuck his mate as his name would suggest, leaving her moaning as he emptied a load of cum into her again and again. Starfire watched with wide, hungry eyes, trying to match her teammates’ pace with her own finger.

She kept finger fucking herself, moaning quietly as her pussy juices dripped onto the ground. She licked her lips, closing her eyes when she felt her orgasm approaching. Starfire could hear it in Terra’s moans. Her climax was fast approaching.

The bed was groaning under them as Beast Boy slammed his cock in and out of her. He pulled on her hair and treated her so roughly, it left Starfire’s heart pounding inside of her chest until finally the moment came.

They all came together. All three of them. Beast Boy’s cum filled Terra’s pussy, and her juices spilled onto him and the bed as Starfire covered her mouth with one hand, moaning into it as her pussy nectar flooded onto the ground.

By the time Beast Boy and Terra could take their eyes off one another, Starfire was gone, already making plans for tomorrow…

Beast Boy looked up from his comic book, hearing several taps at his door. He raised his brow, before walking over to the door and opening it. He found Starfire smiling at him, but looking like she was dressed for winter.

“Hey, Star… What’s with the trenchcoat?” he asked, glancing up and down her body.

“Beast Boy… Garfield. May I come in?”

The young hero blushed slightly at the use of his real name, but he nodded his head, motioning her in. “Sure, Star, but cut it with the Garfield stuff, could ya? Just call me Beast Boy.”

“Oh, but that hardly seems fitting,” she commented, entering his room. He closed the door behind her as he continued to stare in confusion. “After all, you are quite the man now. Just how I am a woman.”

She dropped her trenchcoat. It fell at her feet, and Starfire stood before him with a smile on her face. His jaw hit the ground as his eyes widened.

She was naked. The beautiful, hourglass-shaped heroine was naked, her large breasts on display as she played with her long, scarlet locks. She smiled, walking forward in her purple boots, her only attire.

“Beast Boy. Will you mate with me?” she asked, tilting her head slightly.

“I...I… What?” His eyes were on her tits, ogling them, taking in every detail as if he would wake up and lose the very memory of this moment. He just wanted to enjoy the sight of her, taking in her beauty as she walked forward, hips swaying.

Before he knew it, the woman was in front of him, her tits gently poking at his face. He leaned his head back, staring at the tall woman’s face after several moments. She smiled, before leaning down to kiss him.

Beast Boy felt electricity coursing through him for a moment. His body stiffened as her large breasts pressed against his chest. She wrapped her arms around him, holding him as she leaned down.

The kiss ended as soon as it began, and she licked her lips. She moaned, savoring his taste, before looking at him. “Well?” she asked, and he chuckled nervously.

Really, what was he supposed to do? “W-what about Robin?” he asked, even as his hands rose up to touch her breasts. He was harsh with them, an animal as he squeezed and kneaded her tits. He was drooling as his fingers sank into the soft flesh, and her moans filled his head.

“I don’t want Robin anymore. I want a beast. A real… animal,” she cooed, and that was all he needed to hear.

Beast Boy growled as he suddenly transformed right before her eyes. His suit was torn as Starfire’s eyes widened. She came here to see the beast, but it was clear that Beast Boy had only given Terra an inkling of his true self.

The young man turned into his Werebeast form, covered in fur with long claws on each of his hands. He grabbed Starfire and she gasped, feeling him slam her into his bed. The entire tower seemed to shake as he got on top of her, digging his claws into the bed for a moment, before he began to shrink.

He licked his teeth, naked now as she felt his hard cock gently rub against his leg. “You know, ever since I mastered that form, I’ve been feeling a need.” His eyes almost seemed feral as Starfire’s pussy juices stained his bed. “Care to see?”

“Y-yes. Please, please, fuck-ahhh!” Starfire’s eyes widened again as she screamed in pleasure, feeling his cock filling her cunt. He pushed his dick into her, burying it inside of her as her fingers dug into the bed.

This was not her first time having sex, but it certainly felt that way. The way Beast Boy was holding her down, the way he was slamming into her again and again. The bed was shaking as Starfire had to hold back screams as she felt impaled on his cock.

It hurt. But it also felt incredibly fucking good. She wrapped her arms around him, kissing his forehead before he bit her neck.

“Ahhh! T-that hurt…”

“Want me to stop?” he growled, and she shook her head.

“N-no. Again.”

He sank his teeth into her, letting her scream in pleasure as her inhibitions were devoured by the monster. He licked and sucked on her soft flesh, licking at the marks he left behind. Her pussy squeezed his cock tighter every time he slammed into her. The sound of his cock pounding her wet cunt and his balls smacking her body filled the air along with her cries.

Beast Boy placed a hand on her tits, squeezing one of them, before he pinched her nipple, treating it like a toy to twist and turn. Starfire moaned loudly again, eyes nearly rolling into her skull as her other breast bounced freely from his thrusts.

“How am I compared to Robin?” he grunted, spitting down on her face. Starfire moaned at the humiliating gesture, licking her lips.

“B-better. Y-you’re better!”

He gave her neck another bite as a reward, before he moved his hips slightly. She mewled in pleasure as he fucked her pussy like no one ever had, or ever will, honestly. Starfire wrapped her legs around him, squeezing them together as she felt his tip press against the walls of her pussy, pressing down on her G-spot and making her scream yet again.

“I-I’m gonna cum, I’m gonna cum, I-I-ahhh!” Starfire leaned her head back, rubbing it into the bed as she came to a screaming climax. Her pussy juices drenched his shaft as her entire body began to tremble and convulse against him.

Beast Boy growled again, feeling her squeezing him as his own body trembled. Her boots rubbed against his naked green skin as he waited for the right moment. Right when her pussy was done cumming, he came as well, filling her with his seed and drenching her insides with his cum.

Just when Starfire was coming down, she was brought to a new high as her eyes widened. She cried out again in pleasure, tongue licking the air as she felt her womb being flooded with his seed.

Her brain felt like it was being drowned in the smell of his cock, and the sensations it gave her. She giggled stupidly as her eyes rolled into her skull and her screams faded into a silent moan, trembling on his cock from the pleasure he was giving her.

Her arm and legs went limp, laying uselessly on the bed as Beast Boy slowly slid out of her. She whined quietly, feeling a sudden emptiness as his cum spilled out of her well-fucked womanhood, staining his bed.

He didn’t say anything as he placed his hands on her, turning her over and placing his hands on her ass. He rubbed it, squeezing and playing with each cheek as her face was pressed into a pillow. She drooled on it, moaning again as he spanked her ass.

“Wanna see a neat trick, Star?” She moaned weakly in response. “I’ll take that as a yes. See, I learned how to transform only certain parts of-mmh, me.” Starfire gasped as he pressed the tip of his cock against her asshole.

No man had never fucked her there before, but if she didn’t want this, she wouldn’t be here. She wanted to be fucked by an animal, and if this is what Beast Boy wanted, she’d give it to him. Her hands rose up, grabbing her ass and spreading her cheeks apart to give him better access to her hole.

He rubbed his cum-covered cock against the entrance, slowly sinking it into her as she moaned loudly. Starfire felt every inch filling her as tears formed in the corners of her eyes. She cried from pure bliss, moaning and drooling onto the pillow as her pussy juices and his cum spilled out of her cunt.

It was so depraved. She loved it. She loved him as she suddenly felt his cock changing inside of her. She gasped, before she screamed in pleasure as it became bigger and thicker. It almost seemed impossible, but she knew what she was feeling. A massive, horse-like cock inside of her ass, perfect to fuck her with.

Beast Boy growled, adding more power to his arms as he grabbed her hips and proceeded to impale her once more. His entire, monstrous cock was fucking her, making her scream in pleasure as it pounded her insides.

She was going insane from the treatment, yet her body moved on its own, trying to match every thrust he gave her.

They kept going, shaking the bed under them as Beast Boy’s claws sank into her. The pleasure built inside of each of them, rising and rising until they both felt themselves ready to burst.

“Who owns you?” he growled into her ear.

“Y-yo-oooh-you!” she replied back, and Beast Boy almost wanted to roar in victory. He suppressed that part of his animal nature, before he slammed his cock into her one last time, letting the entire thing fill her. His cum shot out, filling the inside of her ass.

His seed coated the walls of her asshole, painting her insides as his property. Starfire screamed into his pillow, cumming right alongside him as she felt more full than she ever had before. Her body was convulsing and trembling, but the best part was how not a single drop of his cum went to waste.

His animal cock sealed her ass, acting like a buttpluig as Beast Boy sighed. Starfire moaned under him, feeling his cum sloshing inside of her as her mate grinned.

“Ready for round two?”
