Cassidy, finally back in her apartment, still in shock as she leaned against her bedroom door. Face in her hands, slowly sunk to the floor, thinking back to everything she's witnessed within the last hour. She couldn't believe what she saw, heard, felt. He said her name with such passion from so deep that his voice alone could send her over the edge. She hadn't realized that her breathing stopped. What was she to do?

After he said her name, her eyes wide, she rushed from the bathroom, slamming the door to his bedroom shut. She laid, panting, against the back of his door. Her heart was beating so loudly out of her chest she feared that it could be heard echoing through the lair. Fuck! What was Big Red doing to her?

While she stood there in that bathroom, watching him at his most vulnerable all she wanted to do was jump him. She's never expected to feel that way about anyone, ever. Especially considering her previous experiences with the opposite sex. But the deep, guttural sounds that he made, the way he panted and moaned. She bit her lip at the memory, her eyes sliding close as she tried to process everything. Cassidy couldn't stop imagining what it would've been like to trade places and be the water that dripped and cascaded down his carapace, over his biceps, wafting over his muscular thighs. What if she simply joined him? She thought back to how he felt under her hands when they kissed, she wanted to feel his strong, muscular hands wrap around her thighs, caressing her waist, tangled in her hair. She wanted to feel all of him. Cassidy laughed at herself, feeling as though she is the one with an impending mating season.

Back to the present, she tossed her head back, looking at her cracked ceiling and remembering how she rushed from the lair after that. She had thrown her clothing into the bag, and all but ran out of his room. Not seeing anyone in the den she let out a breath she was still holding. She all but threw herself on the couch, dropping her bag to the floor. Melting into the couch, using her sweatshirt to snuggle in as if she was hiding away. Now she sits, waiting for April and Casey to drive her home. She was lost in her thoughts, different scenarios played dirty in her mind when she heard a heavy metal door open, then close. She looked up to see Raphael holding a towel around his waist, looking at his phone as he made his way towards his bedroom. Not noticing the flustered brunette just below, watching his every move as he entered into his room, closing the door behind him. She loved the small smile on his face, but now that she knew why he was smiling, she wanted to tip him over the edge until she brought those sounds and that smile to his features with the help of her hands and her body.

"Hey Cass," April came up behind her on the couch. Cassidy jumped at the sound of being caught in the heat of the moment of envisioning more and more delicious things she wanted to do to the Red turtle.

Gasp! "Apriiiilll!" Cassidy's heart just exploded as her eyes were torn from the red terrapin to look at the perky redhead before her. Cass felt as if she was just caught with her hand in the cookie jar. The cookie jar being Raphael and her hand wanting to wrap all around him.

"You alright? You look a bit flushed," April questioned before placing her cool hand along Cassidy's forehead, then moved to her cheek.

"Uh…uh yeah, I'm good, just have a bit of a headache…" She lied, she wasn't ready to admit that she all but sexually combusted with the mere thought of Raphael having his way with her, and in turn, her way with him.

"Aw, okay, we are headed out, ready?" April said while looking behind her, Casey had walked back into the den.

"Yo Case, I got that new wrap for your bat up here," Raphael's voice boomed from the second story. Cassidy froze as she stood from the couch, she knew she shouldn't, but she looked up at him and she was once again, swept in a boiling heat.

"Throw it down man, we gotta head out. Gotta meet April's aunt for dinner at five and we need to take Splinta' too Northampton." Casey shrugged as he stood at the base of the stairs.

Cassidy still stood, her bag lazily slung over her shoulder, she couldn't stop herself from devouring the eye candy that was Raphael. The sexy bara in front of her. I like this angle… UGH! Get. IT. TOGETHER! Cassidy internally groaned before shaking her head to tear her gaze to land on anything but him.

"Look out Cass…" Cassidy barely heard Casey before she felt the familiar presence behind her.

"Wah…" Cassidy was brought from her thoughts when all of a sudden she heard the screeching of metal. Before she knew it, a heavy presence jumped to land right behind her. She felt an overwhelming shudder which caused her panties to soak. Oh Gawd. Cassidy swallowed her moan. Now that he was so close, her senses were overloaded with the scent of him. If she wasn't still in a brief lapse of shock, and if Casey wasn't looking at her with a wide smirk on his face, she probably would've let out a moan and fell back against the hard chest behind her. She only got one breath in before she felt his strong hands against her waist as he wrapped around her and rested his chin on her crown. She could feel his lips pull into a grin atop her head.

"AWww!" Cassidy internally groaned and wanted to be swallowed up by the sewer floor. Mikey had walked in right at that moment. April's eyes flickered between Cassidy and her tempered friend while Casey had a shit eating grin before he gave them a sultry wink. Donnie and Leo had small smiles on their faces as they joined the group.

Master Splinter watched from behind the group, no one had seemed to notice his presence. He smiled at the union of his second eldest and the woman who had held his son's heart. Splinter had only dreamed that his son's would find the love that each of them deserved. The kind of love that was reserved for a partner, not a brother or family member. The type of love that could help ease the pain and discomfort of being something other than what was considered 'normal.' He continued to smile as he was glad that his small family was expanding and held hope for the future.

"Well, I guess this is goodbye until April," Casey said, before clapping Raphael on the shoulder before splitting to say his goodbyes to the rest of the Hamato's.

"Casey and I will be updating Northampton as we check on Splinter the next few weekends. After the second week in April I have two weeks of vacation time saved up and I'd love to spend it with you all at Northampton."

"Yeah! I MISS the pond!" Mikey bellowed as he wrapped April in a tight hug before dropping her beside Casey.

"I do miss the clearing out there, it was peaceful," Leonardo added in as he leaned to give April a side hug before also clapping Casey on the shoulder.

"I'll have enough space to make upgrades to the security out there and also to the Shell-Raiser. I could also test out some new aqua-tech in the pond."

"Yo! Underwater surfboards!" Mikey yelled before everyone was enjoying the last few laughs before everyone departed.

While the entire family was absorbed in small conversation, Raphael had pulled Cassidy aside, out of view and into the garage. He didn't say anything at first, he was so silent, looking her over from head to toe, as if he was committing her physical form to memory. Once they locked eyes though, it was over.

Raphael's hands went straight to her face, cupping her cheeks before devouring her lips in a bruising kiss. A small gasp escaped her as her one hand gripped where his plastron ended, just above his hip as her other tangled in his mask tails. The book bag fell from her shoulder, she adjusted her arm to let it fall to the floor as he shifted them. Before she knew it, he dipped, gripping her thighs to lift her on top of the metal counters that lined the side of the garage. She assisted him in getting closer by clutching her thighs to hold his hips to her. One of his hands continued to stroke her cheek before wrapping in her hair while the other caressed her clothed hip. Their breathing was becoming ragged as they devoured the other. His hand snuck its way under the sweatshirt band at her hip, the second his skin touched her he growled. His nimble fingers gripped the back of her neck, holding her in place as they separated, pushing their foreheads together as he continued to stroke the dip in her hip, his thumb grazing the crease her body created at the bend of her hip.

"I hate being a turtle." He grunted, his hot cinnamon breath ghosted over her, every space his lips touched had tightened as the air dried the evidence.

"Wha, why?" Her voice concerned, her mind trying to come up with reasons why he'd say that.

"I don't wanna be away from you." He grumbled as he twisted, cheek to cheek before placing a soft kiss to her jaw, trailing more across her cheek, temple before placing another just above her brow.

"Then don't." That stopped him. He lifted his head to gaze into her eyes. She gulped under the intensity of his stare, his eyes were a deep amber yet shined like freshly poured bourbon.

"Haha," a dry laugh left his lips as he dipped to nuzzle against her neck, "you don't know what you're asking babydoll." As if to send home his thought process, he nipped at the skin above her pulse point before blowing, sending pleasurable shivers down her spine. The sensation caused her to arch her back into him, his plastron still pushed up against her front.

"Show me," she felt overly brave and unbearably horny. She has waited months for this, and now that she finally has him, she wasn't ready to let him go.

"Mmm, babydoll… I don't want to hurt you." He stated as he took a step away from her, his hands stayed to rub up and down the edges of her thighs.

"I trust you," she wondered if he could hear her heart,

"I know…I can smell you. Your trust, your want…" She paled.

"Yo-you can smell me? As in…" Cassidy trailed. Thinking back to all those times before he kissed her that she had reacted to him. Does that mean he knew or could smell what she did in the shower all that time ago? Fuck! Could he smell her when she saw him in the shower earlier?

A deep sound vibrated through his chest again, bringing her back to the surface. She imagined him as a lion about to pounce. The purr was only edging her further, she could feel how close she was and now she knew he could smell it too.

"Hey where did Cassidy go?" Leonardo's voice broke their trance. Raphael stepped away from her and pretended to be too busy himself, grabbing random items from the cabinets to her left. She sat stock still on the counter. Afraid if she moved, the friction of her jeans against the cooled metal surface and with him so close would unravel her. She simply leaned over, her hands gripping the edge of the counter to stop herself from falling.

"Hey Leo," he had entered into the garage, the rest of the family in tow.

"Tryin' to get rid of her so quickly Raph?" Mikey teased, making eye contact his brother before shifting to Cassidy to throw her a wink.

"Nah, wanted her opinion on somethin'." He was being so nonchalant as if he didn't just admit that he could smell her desire.

WAIT!

Does that mean all the brothers and possibly his dad could smell her wet desire for their temperamental family member? She blanched, as her mind raced with more questions, trying to distract herself from her once growing orgasm that was now diminished as if a bucket of ice was thrown on her.

"Well, we gotta head out now, Casey will take Splinter as I drop off Cassidy. He'll bring back the truck and I will swing by to pick him up," April stated as she gestured towards Casey and the garbage truck, "If you guys need anything, food, tools, etc. just send a text and we'll run our "MNT" Protocol."

"MNT," Cass questioned, not quite sure what that meant.

"Mutant Ninja Turtle babe!" Mikey beamed, sending her another wink as he wiggled his head and crossed his arms, looking as if he was the star in the newest boy band. He's definitely the type Cassidy thought, giggling to herself.

That was the last of it before everyone exchanged their last hugs and goodbyes. The last image that was playing over and over in her head was Raphael who had leaned against his bike, arms crossed and a smirk plastered across his face as he watched her in the backseat of April's car.

Her reverie broke as her cell phone rang, startling her as she fumbled in her pocket before seeing that it was April.

"Hey Ape," she didn't even get to finish her greeting before the talkative redhead interrupted.

"Cassidy! Girl! You need to tell me everything!" April's excited shrill echoed through the phone, Cassidy sat up from the floor, clicking the speaker button as she got around putting away all of her clothes to get ready for a shower.

"Tell you what?"

"YOU slept with Raph!"

"WAHT! We DIDN'T sleep together," not yet anyway, Cassidy thought before it really clicked with what April said.

"NO! I know you didn't sleep with him, I meant that you two slept, actually went to sleep together."

"Yes, we slept side by side…" Cassidy was relieved that April had reworded her previous accusation. Not that Cassidy hasn't thought about what it'd be like to have the powerful terrapin show her exactly what he'd do to her. Maybe show her what he was thinking about doing to her while she watched him in the shower.

"AWW!" April squealed,

"Wait, how do you know," Cassidy didn't tell anyone and she was sure that Raphael's family didn't know that he had stayed with her.

"Raph asked Casey something earlier and Casey grilled him about you and Raph let it slip that you two slept beside each other."

"Oh..yeah," Did Casey find it weird that Cassidy was so attracted to his best friend, who just so happened to be a mutant, ninja fighting, turtle? Not that his opinion of her mattered, but she wanted to know if he approved of her for his best friend.

"Did anything else happen? You two looked awfully comfortable this morning at breakfast," Cassidy could all but hear the wink and sultry smile that April was probably giving while on the phone.

"Yes, uh-I… Oh god April, I all but jumped him." Cassidy admitted, she knew April wouldn't judge her and she was so thankful to have another female to talk to about this. April did understand albeit briefly, but she understood nonetheless.

"Tell. Me. EVERYTHING!"

It has been a hellish week since Cassidy and their small, human, friend group and his father had left. Raphael was pacing back and forth in the weight room. He had busied himself with fixing some parts on Stella and he wanted to blow off some steam before going on patrol tonight. But as he continued to wear a hole in the concrete, only thoughts of Cassidy filled his mind. He knew that this mating season was going to be H.E.L.L. His brothers were already ruthlessly teasing him about it. Especially Mikey who would constantly bring up Cassidy, her fine ass, her curves, the dimple on her cheek when she smiled. Raphael knew he did it just to get a rise out of him, and it had worked every damn time. Which of course landed them both in the Hashi by Leo's command. Even though their father was not there, his teachings and punishments were still very much in order thanks to his 'teacher's pet,' of a son, Lame-o-nardo. Splinter had called to check in, and Leonardo blabbed to Dad.

UGH!

Raphael grabbed the closest dumbbell off the rack and threw it against the concrete wall of the small tunnel that was his weight room. The dumbbell had a few more chips and dents as it dropped to the floor. Tensions were high and the brothers all but left each other alone unless it was time to eat. Training was done individually but they held each other accountable. Leonardo would use the dojo in the morning, Raphael would use it at night and Mikey and Donnie would skip in and do just enough to not get bitched at by Leo.

But Raph knew he shouldn't give his eldest brother such a hard time. Leo wasn't as overbearing like he used to be. He understood that each of his brothers dealt with this particular season differently.

Despite the distractions, the brothers still lived underground, there wasn't much to do. Even more so now since they all avoided each other the majority of the time. Raphael was brought out of his stewing as his phone rang.

"Hey handsome! What are you up to?" Cassidy's sweet voice sang, god he adored this woman. They've talked or texted damn near every day, sending memes to each other, or a simple goodnight/ good morning text. He missed her and she missed him just as much. This season couldn't be over quick enough.

"Hey babe, about to bench," facepalming, he didn't know why but he wasn't going to let her know he was bored and thinking of her. Nah, he had to prove that he wasn't just a horn dog 25/8.

"Ooh nice," his member twitched the way her voice dipped in that sexy way it did, "well, I have a buddy at work that is selling his and I was wondering if you'd help me fix it…"

"What's the engine?" This was a welcome distraction.

"1970s Honda, CB 350, silver with black leather."

"What's it look like?"

"I text some pictures to you later, but would you be willin' to help me spice it up?"

"Do ya need any help gettin' it?" Why, at the mention of leather, he pictured her in nothing but a black leather jacket and nothing else. She was leaning over his cycle, her pert ass shaking for him as she gave him that 'come hither,' look. He shook his head to vanish the image.

"Nah, Casey helped me. We took it to the garage at Northampton the other weekend when we visited Splinter." Even though Raphael knew that Casey and April were an item, he didn't like how chummy Casey was with his girl. Especially when he wasn't able to be the one to help her.

"Oh," He didn't know what to say. He didn't want to speak too much because he knew that his anger would show through.

"Yeah, but I figured I'd bug you about it now, so when we see each other in a few more weeks we could work on it together. Casey was talking about how you and Donnie have fixed all of his vehicles…"

Raph heard Cassidy ramble on in that cute, excited way that she does but he instantly bulked when he heard her sweet voice say his brother's name. It wasn't anyone fault but his damn, fucking hormones. He only wanted his name coming from her lips. Not Casey's, not Donnies, only his. His mind brought him back to when she had said his full name in breathy whispers and moans. Raphael. RAphAeL.

He wanted to make her say it again, for real this time. Not just a memory that he's manipulated to fit his unlimited fantasies about her. Their conversation continued for a bit longer and he was tired of standing around not doing anything in the weight room so he moved to hide in his room.

Still talking with Cassidy, he kicked some blankets and clothes from the edge of his mattress when something small and black caught his eye. Cassidy had started to talk about how her boss Stan did something funny the other night at work. Raphael didn't quite hear as he bent to pick up the mysterious black fabric. Once he stood eye level, he choked. In his hands was a pair of black lace panties. The only person this could belong to was currently rambling to him about her job over the phone.

"Cassidy…" His voice came across deeper than he anticipated but he was trying to control his body. It was futile, his body already responding and the previous thought of her came to mind, black leather jacket and this specific pair of panties hugging her curves as she walked towards him, his helmet swinging in her hands. Her eyes lidded as they looked like a deep teal.

"What?" Her sweet voice asked, completely oblivious to the thoughts and sensations that were coursing through his body. He didn't want her to worry.

"I'll help you, I'll mock up some ideas and send them your way. I gotta go, Donnie's callin' me."

"Oh okay, talk later Red!"

"Laters baby." He hung up. Did he really just say that? Laters baby? Fuck, he missed her. Missed the way she molded to his hands, touching him, kissing him. At that thought he looked down, the pair of underwear still in his hand. He'd never tell her he had them, maybe she'd forget that they were packed. Yeah, she'd forget or he'd distract her if they were ever brought up. He'd blame it on Mikey, he was the most verbal with this kind of thing, maybe Cass would simply shake it off. His dirty thoughts clouded his brain as he laid back on his bed, panties bunched in his large fist that balled against his forehead. Her scent was minimal, but still lingered. She had, unknowingly played in every single one of his fantasies and he'd be damned if she ever found out what exactly he did with the lacy pair of panties in his hand.
