FLASHBACK 8 MONTHS EARLIER, JUNE 22

"I'm off ta the costume party, Leo," Raph told his mate. When Leo said nothing, Raph sighed and said, "Look, I'm sorry for bein' a dick. How many times do I gotta tell ya that I'm sorry?"
"I said I accepted your apology."
"Yeah, ya said ya accepted it, but ya ain't showin' that ya have. Ya still look pissed."
"Do you think we're in a rut?"
"Why would ya say that?"
"I don't know. Things don't seem as passionate as they were before and we never spend much time with each other anymore. You're always working out and…"
"So ya feel neglected, huh?"
"Kind of, yes."
"Leo, our relationship's fine. I love ya so much and when I get home, I'm gonna show ya how much, okay?" Raph said, and kissed him on the lips. "Come with me."
"I hate parties and you'd better not drink any booze. Promise me."
"I promise."
"What if there's a really hot girl there?"
"Oh, yer jealous?" Raph said, and smirked. "Ya think I'm gonna cheat. Look, I like guys and girls, but the only person I want is ya, Leo, and nothin' will change that. I ain't gonna cheat, so stop worryin'."

Leo's shoulders relaxed and he said, "Okay, Raphie. How do you think the guys will take it when we tell them about us?"
"I don't know, Leo, but I do know that we've been together two years and they've been the best years of my life. I couldn't live without ya and I look forward ta growin' old with ya."
"Me too."
"Leo, whatever happens, we'll deal with it together and we won't let anyone separate us."
"No, we won't. I love you. Go have fun."
"Love ya too," Raph said, and kissed him deeply. "I'll miss ya."
"Ditto."

Half an hour later, Raph met Casey at his apartment and they made their way to the party. "So whose gonna be at the party, Casey?" Raph asked.
"Some people I know, including my cousin, Brandi. She's a real fox. Blonde, busty, blue eyed. All the guys love her. You will too."
"Is there gonna be booze at the party? Leo doesn't want me drinkin'."
"One drink won't hurt and Leo doesn't have to know, does he? Let your hair down. Hahaha. I mean, just relax and have fun, Raph. It's just me, you, some friends and there'll be hot chicks I'm sure."
"What 'bout April? Ain't ya with her?"
"It's casual sex, Raph. We hook up when we want to, but we see other people. Best kind of arrangement. Maybe you'll meet a cool girl."
"I'm not lookin' ta meet anyone, Case!"
"Well, you should, otherwise you're going to die a virgin, Raph."
"Listen, Case, I'm kinda with…
"We're here," Casey said, and rang the doorbell.

A minute later, a blonde, blue eyed, voluptuous girl, dressed in a red, skin tight mini dress and matching heels, opened the door. "Casey!" she exclaimed. "Good to see you, cousin."
"Hey, Brands."
Wow, Raph thought. She is stunning. Fuck it. The kinda girl I'd date. No, I shouldn't think 'bout her. I have Leo, whom I love and we're gonna have a bonding ceremony as soon as we've told the family 'bout us.

"And whom do we have here?" Brandi asked, gazing at Raph, who flushed.
"I'm Raphael-Raph. Nice ta meet ya."
"Love the costume. It looks so real."
"Yeah, I've grown kinda attached to it and wear it all the time."
"Hahaha. What a kidder. Where've you been all my life, handsome? Come inside, please."

Brandi showed them into the lounge, where many people were gathered, and said, "Help yourself to whatever you want, guys."

The music blared. Techno, Raph thought. Figures. I hate it. I think I should go home. I don't belong here.

"And you're not dressing up, cuz?" Casey asked.
"Nah," Brandi said, shrugging her shoulders. "Didn't feel like it. Please drink with me," she added, pouring champagne into two flutes and handing them to Casey and Raph.

"I'm not allowed ta have alcohol, Brandi," Raph said quickly. "I promised my brother."
"Promises are made to be broken and one glass won't hurt. Go on."

"She's right, Raph," Casey said. "Go on. Just one. Leo will never know."
"Fine," Raph said, and took a long sip. "This is good, Brandi."

"Should be," Brandi said. "It's expensive. My dad only buys the best, you know. Hey, Raphael, what do you think of my house?"
"It's nice," Raph said, and took a long sip. "Beats livin' where I do."
"And where do you stay?"
"Manhattan. Down market."
"How old are you?"
"Just turned fourteen. Ya?"
"Fifteen. Where do you go to school?"
"I'm home schooled."

"Oh, hey, babe," Casey said, spying a girl he knew. "Let's go talk someplace quiet."
"You're on!" the girl said, grabbing his hand and leading him away.

"Are those muscles real, Raph?" Brandi asked, touching his biceps.
"Yeah. I work out a lot. Leo, that's my…"
"You straight or gay? I know you've been checking me out, but I want to know. I'm both, but I prefer guys."
"I haven't been checkin' ya out."
"All guys do. It's okay. You can admit you have. I won't be cross."
"Actually, I'm thinkin' I should go home," Raph said, feeling uncomfortable. "My lover's waitin' for me. We're madly in love and gonna have a bonding ceremony soon."
"Bonding ceremony. What? Are you an animal or something?"
"I'm…."
"No, please don't go, Raphael. You're the most interesting person here and my cousin's occupied. Please. It's my birthday. You'd hate to disappoint me on my birthday by leaving so early, wouldn't you?"
"I promised Leo I'd be home by ten and it's nearly ten."
"Is Leo your babysitter or something?"
"My mate."
"Wow, interesting. Why don't you say boyfriend?"
"It's a human… never…"
"Just two more drinks. Please. Then you can go home. Pretty please," Brandi begged, and pouted.
"Fine. I'll tell Leo I'll be home by eleven, but Brandi, ya gotta know, me and ya ain't gonna happen. I'm with Leo and I love him."

Raph sent Leo a text saying he'd be home by eleven. Then he and Brandi sat on the couch and talked. She kept him plied with drinks, but only sipped at one all evening. The turtle didn't notice and, as the alcohol took effect, his tongue loosened and he began telling her things he'd never told anyone else: who his family were, that his dad was a rat, he lived in the sewers, his romance with Leo, his biggest dream, et cetera. Brandi listened and kept plying him with drinks.

At eleven thirty, an intoxicated Raph said, "I don't feel so hot. I think I need ta lie down, Brandi."
"You can rest in my room, Raphael," Brandi said, helping him to his feet and leading him up the stairs to her room.

Once in her room, Brandi quickly began removing his gear and belt, dumping it on the floor and helping him into bed. "What are ya doin', Brandi?" Raph asked.
"Making you more comfortable, Raphael," she said, and kissed his plastron. "Do you like that, turtle boy? I think that's what you are with talk of bonding and mates, right?"
"Yeah, look…."
"Shh, baby. You're going to be fine. Now, where's your cock. In a pouch, right? Drop it down, Raphael. For me."
"Leo…"
"Isn't here," she said. "I want you." Brandi kissed him deeply and stroked between his legs. "I want to fuck you so bad, Raphael. I wanted to from the moment we met."

Letting out a loud churr, an inebriated Raph dropped down, his ten inch and purple cock leaking precome. "Oh, here we are," Brandi purred. "It's ugly, but it'll do. I'm horny and you're the only one at the party I haven't banged, so guess what? Your lucky day. You get me."

Brandi rubbed his cock until it was erect. Then she lowered herself onto it and began to rock, arching her back, so that his cock went in deeper. Raphael churred loudly, his eyes closed in sheer bliss.

Meanwhile, when Raph hadn't come home, a worried Leo left a note to the others saying he was going out and would be home later. He climbed into the van, punched in the coordinates of Raph's cell phone, got the location of where it was, and said, "I hope you haven't gotten into trouble, Raph!"

Leo revved the engine and drove towards Brandi's house. When he arrived, he tried the door and found it was unlocked. Going inside, loud music assaulted his ear slits and he grimaced. "Oh, you're a cutie pie," a brunette girl in a skimpy silver mini dress and matching heels said. "I'm Heather."
"Seen a red-masked guy in a turtle costume?"
"Maybe. Why don't we play and…?"
"Look, girly, have you seen him or not?" Leo demanded, his sapphire eyes flinty.
"You don't have to be rude!"
"I'm not. I'm just looking for my kid brother. Have you seen him?"
"If I answer, then can we play?"
"Fine."
"I saw him go into Brandi's room. Second on the left upstairs. They're probably fucking. She fucks everything. Now, can we play?"

Leo sprinted up the stars, barged open Brandi's door and his jaw dropped. There was HIS precious Raphael being straddled by a girl. "Oh, my God. Haven't you heard of knocking?" Brandi snapped, turning her head and glaring at Leo. "There are doors for a reason, you know. Privacy! Oh, you must be Leo. He spoke about you. Said you sucked in bed and he wanted to move on. Now he has."

Raphael had fallen into a drunken stupor, so he was oblivious to the on goings.

Feeling like his world had crumbled and his heart shattered into a million pieces, Leo ran out of the room and house, tears streaming down his face. I trusted him and he cheated, Leo thought, clenching his fists. NEVER again. Me and Raph are done forever and he can go fuck himself.
