Chapter 4: The Big Bang

Yukio drags his tongue across Rin's bottom lip. "He-" Rin tries to say. Yukio slips his tongue in Rin's mouth. "Mmph!" Rin feels Yukio's tongue in his mouth and is shocked, but he just goes with it. Yukio pulls away and looks Rin in the eye. "Rin, I don't hate you and I never will." He says. "I thought you hated me." Rin is shocked. "What? Why?" He says. "I thought I always made you mad at me. Every time you get all happy about something I usually make you angry when I've always loved your smile and how your eyes light up when you're excited." Yukio says. Rin hugs Yukio tightly. "Rin?" Yukio is confused. "I love you too Yukio" Rin says. Yukio's eyes go wide.

Yukio smiles and hugs back. "So... what do we do now?" Rin asks unsure of what to do. "Well, because of all this... do you... wanna go out?" Yukio hopes Rin says yes. Rin blushes. "Fuck yeah! You don't know how much I wanted this!" He says. Yukio smiles gladly. Rin leans in and kisses Yukio passionately. "Well, goodnight Yukio." Rin turns on his side to sleep. Yukio does the same and wraps his arms around Rin and hugs him close. He starts to kiss down Rin's neck. "Yukio?~" Rin tries to say, but it comes out as a moan. Yukio drags his tongue over where he kissed and starts to suck and bite. Rin moans. Yukio moves down to Rin's collarbone making more red marks.

Yukio gets a hard-on from the sound of Rin's voice as Rin gets one from the pleasure. Rin feels Yukio's erection against his butt and blushes. Both feel their pants tightening more and more. They both want themselves to get more space by taking off their pants. Yukio grinds himself against Rin and both moan quietly. Yukio gets on top of Rin and begins to to undo his shirt. After Rin's shirt is completely off, Yukio starts caressing his chest and stomach. He pinches, bites, and sucks Rin's nipples making them perk. "Ahhh~ Yukio~" Rin moans. Yukio moves down to the edge of Rin's shorts and starts to palm him through them. Rin is panting and moaning. "Hey, Rin, I'll stop if you want me to." Yukio says. He stops palming Rin. "No! Uh.. I mean... it's okay!" Rin says wanting Yukio to keep going. "Well, I guess I'll do this then." Yukio pulls Rin's shorts and boxers off in one swift movement.

Rin's hard-on springs out and Rin sighs. Rin realizes he's the only one naked. "Hey, why am I naked while you're still fully clothed?!" Rin says loudly. "Oh, sorry." Yukio begins to undo his shirt. Once that's off, he tries to undo his pants, only to be stopped by his twin. "I wanna do it.." Rin says a little nervous. Yukio moves his hands and Rin undoes his pants. Rin pulls off Yukio's pants and boxers. When Yukio's erection springs out, Rin stares in amazement at the size. "Dang!" Rin whispers. "What?" Yukio can't quite make out what Rin said. "Nothing." Rin says. Will it even fit? He thinks. Yukio hovers over Rin and kisses him. He moves down in between Rin's legs and grabs his cock. Yukio slowly pumps his hand, earning a moan from Rin. After a minute, Yukio puts Rin's cock in his mouth and sucks hard. "Ahhnngh!" Rin moans loudly. "Nii-San, not too loud, you'll wake up Kuro." Yukio says.

(A/N: Kuro is currently up, listening at the door, blushing hard HAHA)

"It's kinda hard to nngh keep quiet when nngh you do that." Rin says. Yukio sucks again, really hard. "Ahhngh!" Rin moans louder than before. "Rin you're way too loud!" Yukio says picking up his shirt from the ground, pulling the tie from it.

(A/N: Kuro jumped back hearing the loud moan)

Rin's eyes go wide as Yukio ties the tie around his mouth. "Mmph!" Rin tries to say, only to be muffled by the tie. He starts throwing his arms around wildly. Rin hits Yukio's chest over and over until his brother gets sick of it. "Rin cut it out!" Yukio says annoyed. Rin doesn't stop. Yukio gets an idea. Yukio grabs the tie from Rin's shirt. He looks up at Rin with a devilish grin. Rin starts to throw his legs around with his arms. Yukio gets back on top of Rin. "MMPH!" Rin tries to yell. "I'm sorry Nii-San, but I don't want to deal with that right now." Yukio says. Yukio tries to catch Rin's arms, but can't. He leans down and licks the tip of Rin's cock. "Mm!" Rin moans as his arms fall on the bed, his hands grabbing fistfuls of the blanket. Yukio quickly grabs his wrists, pinning them above his head. Rin growls at Yukio. The younger twin smiles. "It's okay Rin. Would I ever hurt my dear older brother?" He says. Rin shrugs the best he can. "Well that was mean, don't you think?" Yukio says. Rin motions to the ties as if to prove his point. Yukio laughs. Oh, you want me to let you go?" He says. Rin nods. "Well, how about this, I'll let you go...but, you have to choose whether you're unable to speak (the tie goes around your mouth), or you're unable to move (the tie goes around your wrists). If you say no, it's both." Yukio says. Rin glares up at him. He sighs and nods his head. Yukio lets go of Rin's wrists and takes the tie off his mouth. "What will it be?" He says. Rin thinks for a while.

If my mouth: I won't be able to speak, or breathe very well.

If my wrists: I can't move.

He thinks this through. "Well?" "My wrists." Rin says. Yukio ties Rin's wrists together above his head. He starts sucking Rin again. Rin moans repeatedly. Yukio suddenly sticks a finger inside his brother. "Ahh!" Rin yells in slight pain. "That hurts!" "It'll stop hurting, just be patient." Yukio says to try to calm Rin down a little. Yukio waits a little while to insert a second finger. "Nngh!" Rin gets another slight pain, but it wasn't as bad as the first. Yukio continues that for a while before he takes his fingers out of his Nii-San. He lifts Rin a little and positions himself at his entrance. "Rin, I'm gonna put it in okay?" Yukio says. "Uh...okay." Rin replies. "Just tell me when you're ready." "Ready." Yukio pushes in slowly. "AHH!" Rin yells. "Are you okay Nii-San?" Yukio asks worriedly. "Uh...y-yeah." Rin says. "You can start moving..." Yukio pulls out and pushes back in at a slow pace, starting a good rhythm. Rin is in pain. Yukio notices a tear running down Rin's face. He wipes it away as more form. "Nii-San..."
