As Cassandra Cain stepped into the gym, her eyes scanned the area, immediately honing in on Stephanie Brown. Steph, the tall, blonde, white girl, was in the middle of the mat, her lithe body twisted and contorted in a complex series of movements that Cassandra recognised from their previous sparring matches.

Cassandra walked over to her, her black hair swaying as she moved. Steph's blue eyes flicked up to meet hers, a wide grin spreading across her face as she straightened up. "Cass!" she exclaimed, rushing over to her friend and pulling her into a tight hug. "I'm so glad you could make it!"

Cassandra returned the hug, her body tense but not unwilling. She had never been one for physical affection, but Steph was different. Steph was always so... alive. It was infectious, really.

"You ready to train?" Steph asked, pulling back and grinning at Cassandra. "I've got some new moves I want to show you!"

Cassandra nodded, her eyes flicking down to Steph's tight gym clothes. She could see the outline of Steph's nipples through the thin purple fabric, and her cheeks flushed as she looked away. She had never really thought about Steph that way before, but now... now she couldn't help but feel a strange fluttering in her chest.

Steph noticed her blush and raised an eyebrow, her grin widening. "Something wrong, Cass?" she asked, her voice low and teasing.

Cassandra shook her head, her eyes darting back up to Steph's face. "No," she stated simply. "I'm fine."

Steph chuckled, her eyes sparkling with mischief. "Okay, then," she said, stepping closer to Cassandra. "Let's get started."

Cassandra always took it easy on Steph when they sparred together. Occasionally she even let the busty blonde win. Steph was making such an effort today that she let the blonde tackle her down to the floor. Her back pressed to the mat, she felt Stephanie's warm body pressing down on top of hers. Both girls were sweating by this point.

"I did pretty good there," Steph breathed out.

Cassandra nodded, her heart pounding in her chest as Steph's body pressed against hers. She could feel Steph's breasts pressing into her, and she swallowed hard, her mind racing.

Steph's hands were on her hips, and she could feel the other girl's fingers digging into her flesh. "You feel good, Cass," Steph murmured without thinking, her lips brushing against Cassandra's ear. Steph looking hypnotised in that moment.

Cassandra's breath hitched in her throat as Steph's lips moved down to her neck, her teeth nipping at the sensitive skin. She could feel her body responding, her nipples hardening and her pussy growing wet.

"What are you doing?" Cassandra asked, her voice barely above a whisper.

Steph pulled back, her blue eyes meeting Cassandra's dark ones. "I'm sorry," she gasped, her voice sincere, blushing bright red. "I didn't mean to... I just... I can't help it. The adrenaline must have…."

Cassandra's eyes narrowed in understanding. She had heard of this before, the way that a rush of adrenaline could make people do things they wouldn't normally do. She had never experienced it herself, but now... now she couldn't help but feel a strange thrill at the thought of Steph wanting her.

"It's okay," she said, her voice soft. "I understand."

Steph's eyes lit up, and she grinned.. "Really?" she asked, her voice hopeful.

Cassandra nodded, her heart pounding in her chest. Steph didn't hesitate, her lips crashing down on Cassandra's in a passionate kiss. Cassandra's eyes widened in surprise, but she didn't pull away. Instead, she found herself responding, her lips moving against Steph's in a dance as old as time.

Steph's hands were in her hair, tugging at the black strands as she deepened the kiss. Cassandra could feel her body responding, her nipples hardening and her pussy growing wetter.

She reached up, her hands moving to Steph's waist, pulling her closer. She could feel Steph's curves pressed against her, and she couldn't help but let out a low moan.

Steph pulled back, her breath coming in short gasps. "Cass," she murmured. "I want you."

Cassandra didn't hesitate. She pushed Steph down onto the mat, her body moving on instinct. She straddled the other girl, her hands moving to Steph's breasts, tugging her sports bra out of the way.

Steph's nipples were hard, and Cassandra couldn't help but pinch them, rolling them between her fingers. Steph let out a low moan, her hips bucking up against Cassandra's.

Cassandra couldn't help but smile, her left hand moving down to Steph's pussy. She could feel the heat emanating from the other girl's core, and she couldn't help but feel a thrill at the thought of making her cum. The other hand pinched Stephanie's aching nipple hard.

She slipped her left hand's fingers inside Steph, her thumb moving to rub circles around the other girl's clit. Steph's moans grew louder, her hips rolling desperately against Cassandra's hand.

Cassandra could feel herself getting wet, her own pussy aching with need. She slipped another finger inside Steph, her thumb continuing to circle the other girl's clit.

Steph's moans turned to cries, her body shaking as she came. Cassandra didn't stop, her fingers moving in and out of Steph's pussy, her thumb continuing to rub circles around her clit.

Steph came again, her body trembling beneath Cassandra's. Cassandra finally pulled her fingers out, bringing them to her mouth and sucking them clean.

Steph's eyes were glazed over, her chest heaving as she tried to catch her breath. Cassandra stood up, offering her hand to Steph.

"Come on," she said, her voice low and sultry. "Let's take this to the bedroom."

Steph nodded, taking Cassandra's hand and allowing herself to be pulled to her feet. Cassandra led her to the bedroom, pushing her down onto the bed.

She stripped off her clothes, her body on display for Steph. She crawled onto the bed, straddling Steph once again.

She reached for a dildo, coating it in lube before pressing it against Steph's pussy. Steph let out a moan, her hips moving up to meet the dildo.

Cassandra pushed it inside her, her hand moving to rub circles around Steph's clit again in the pattern she'd found Steph responded most desperately to. Steph's moans grew louder, her hips moving faster against the dildo.

Cassandra could feel herself getting wet again, her own pussy aching with need. She reached down, rubbing her own clit now as she fucked Steph with the dildo.

She could feel herself getting close, her hips grinding against Steph's writhing body. Steph's cries became screams, her body shaking as she came.

Cassandra couldn't hold back any longer, her own orgasm crashing over her. She collapsed onto Steph, pulling the dildo out of her as she caught her breath.

Steph wrapped her arms around Cassandra, holding her close. Cassandra smiled, her head resting on Steph's chest.

"That was amazing," Steph breathed out.

Cassandra nodded, her fingers tracing patterns on Steph's skin. "Yeah, it was."

They lay there for a few more minutes, enjoying the afterglow of their lovemaking. Cassandra knew that they would have to get up and get back to their training eventually, but for now, she was content to just lay there with Steph.
