Kagami pulled Aomine straight to his bedroom.  Aomine couldn't help smirking at that, "It's only been a day, can't wait to have your hands on me again?"

Kagami's cat ears twitched in frustration and he lashed his tail, "I just... wanted a little privacy, okay?"

"Oh?"  Aomine leaned up to whisper in Kagami's cat ear, he had to see if Kagami could actually hear with them.  "What's so secret that you have to tell me in private?"  Aomine slowly licked Kagami's ear, he just couldn't resist, it was fluffy and soft and actually a part of his boyfriend.  Kagami visibly shivered and his ears flicked away from Aomine.  Aomine stepped back a little to see just how red Kagami was becoming.  He smiled, "So cute..."

Kagami looked away, pulling Aomine inside his room and shutting the door behind them.  He stood facing the door, keeping his back to Aomine as he said, "It's just that every month for three days... these ears and tail grow on me.  It's always on the full moon and I'm always so..."  Kagami paused and Aomine could see a blush reddening his ears.  "I just can't be around you when they grow on me."

Aomine walked up behind him, wrapping his arms around Kagami's waist, pulling him closer to him.  "So that means they're really a part of you, hmm?"

"A-Aomine!"  Kagami glanced back at Aomine.  He was biting his lip and Aomine could see a little bit of a fang digging into his lip.

He smiled, one hand going up under Kagami's shirt, the other reaching down to stroke Kagami's tail.  "You're so sexy.  I want to see all the parts of you that've changed."  He leaned in, kissing Kagami deeply.  Kagami readily kissed him back, bringing a hand up to hold Aomine's cheek, he even moved his tail to wrap around Aomine's torso.  Aomine teased Kagami's lips open, sliding his tongue past them and rubbing it along Kagami's little cat fangs.

Kagami shivered and moaned into the kiss.  He suddenly opened his eyes, pushed Aomine back and stepped away.  His face was flushed, lips still slightly parted, Aomine was finding it hard to stop.  Kagami shook his head, "I shouldn't..."

Aomine stepped forward, resting his hand on Kagami's waist.  His expression completely serious as he said, "Can't or won't?"

Kagami bit his lip, showing that cute little fang again.  He seemed to relax, giving in and wrapping his arms around Aomine's shoulders.  He kissed him again deeply, pulling back to say, "I want to, I really want to~"

Aomine smiled, picking Kagami up by the waist and carrying him over to the bed.  He laid him back on the bed, sitting in between Kagami's legs.  He licked his lips, "Now let's see just what has changed."

Kagami blushed heavily, looking up at Aomine, his ears twitching and his tail reaching around to wrap around Aomine's forearm.  Aomine looked at Kagami's tail, chuckling, "I think it likes me."  He reached back to stroke Kagami's tail from the base where it connected to his body.  Kagami bit his lip, trembling from the touch.  Aomine smiled, "So it's more sensitive there."  He leaned down to whisper in Kagami's cat ear, "What about here?"

Kagami kept trembling, nodding slightly, "Aomine..."  He wrapped his arms around Aomine's shoulders, holding him close.

Aomine moved down to kiss Kagami deeply, intertwining their tongues.  Kagami's tongue even felt a little rougher than usual.  Aomine was so amazed with what happened to his boyfriend.  He moved his hand up and under Kagami's shirt, fingers tracing up to play with Kagami's nipple.  Kagami moaned loudly into the kiss.  Aomine found it so sexy, he couldn't help pinching Kagami's nipple.  This time Kagami broke the kiss, pushing his head back against the bed, moaning heavily.  Aomine looked at him in awe, "Feeling it that much, huh?"

Kagami looked up at him, face flushed, "I-it just feels... more sensitive than usual..."

Aomine gulped, he loved how sensitive and just a little bit shy Kagami was being, it was even better than usual.  He lifted Kagami's shirt, pulling it off.  He looked down at Kagami's nipples, still rubbing one of them.  "Aren't they bigger than usual too?"

"I-I don't know..." Kagami looked away, face completely red.  Aomine knew he was right.  He leaned down, licking one of his nipples and earning a gasp and a loud moan from Kagami.  Aomine continued to suck is nipple, making Kagami make more moaning sounds, it was driving Aomine crazy.  His pants were so tight around his member, he wanted to put it in Kagami so badly.  Kagami dug his hand into Aomine's hair, "Aomine, please... I want you in me..."

"As you wish," Aomine smirked, leaning up to kiss Kagami.  There was no way he could deny that request.  He leaned back to take off his own shirt and pants, exposing his erection and then he pulled off Kagami's pants.  He placed two fingers at Kagami's entrance and slowly pushed them in, they went in so easily, Kagami wasn't tight at all and on top of that, his insides felt like they were already lubed up.  Aomine smiled, "Is it just me or are you already all wet down here.  Have you been playing with yourself?"

Kagami blushed a bright red, hiding his face behind his hands.  His voice was muffled through his fingers, "I haven't!  It's just...my body..."

Aomine smiled, taking his fingers out since Kagami already seemed prepared.  "Sexy."  He smirked as he pressed his member up against Kagami's ass.

Kagami's hands flew from his face and he reached down to hold Aomine's arm.  "D-do you have a... condom..?"

Aomine looked at him for a moment, surprised by the request.  Usually Kagami didn't care, even liked the feeling of doing it without a condom.  He nodded, turning to get one out of his pants pocket, he usually always had one just in case and it seemed like today was that just in case scenario.

He put on the condom, before pressing himself up against Kagami's entrance again.  He leaned down to kiss Kagami as he pressed himself in.  Kagami kissed him back, wrapping his arms around him tightly and moaning into the kiss as they became one.

Aomine pushed all the way in and started to move.  Kagami was already moaning a lot, making their kiss vibrate.  Every one of Kagami's moans made Aomine want to love him harder, so he kept moving faster.  Kagami had to break the kiss because he was panting and moaning so much.  Kagami was always a bit of a screamer when they had sex, but this, this was more than usual.  Aomine couldn't get enough, just looking at him.  He wanted to feel Kagami's hot insides on his skin too, he knew that it would be different than usual too, with it seeming to have self-lubricated.

Kagami was digging his fingers into Aomine's skin on his back, leaving visible scratches.  He kept panting, with Aomine moving so fast in him, it felt so good, he couldn't hold out long.  Aomine could see the pleasure on his lover's face, he whispered hoarsely in Kagami's ear, "Don't hold it back."

The words sent a shiver down Kagami's back and it was enough to make him lose control.  He pushed his back, whole body tightening around Aomine as he climaxed.  The sudden tightening around him was enough to make Aomine come too.  He leaned down to kiss Kagami again.  Kagami kissed him back, parting for air and to keep catching his breath.  Kagami breathed out, "Ah... no good..."

Aomine's eyebrows hit the ceiling.  He couldn't believe Kagami, especially not after he saw all the pleasure he was in.  "What?"

Kagami shook his head, "It's just... I want to feel you release it inside me."  Kagami looked up at Aomine with a begging expression.  Aomine gulped, that needy look on Kagami's face was just too good.  Kagami begged, "Please... again... with just you."

Aomine pushed some of Kagami's hair out of his face, looking at him seriously, "You sure?  You were pretty adamant about the condom."

"Yes~" Kagami nodded, resting a hand over Aomine's, "I want to feel all of you."

"Then how can I resist?"  He smiled, kissing Kagami before pulling out and taking the condom off.  He leaned down to kiss Kagami again, their tongues intertwining.  He started to grind his hips against Kagami's and Kagami started to moan, wrapping his legs around Aomine's waist.  Aomine could feel that his lover was already hard again, he was amazed at how quickly his body was reacting.  He started to get excited again too and after a few moments, lined himself up with Kagami's entrance.  He pushed in and he could just feel how hot and wet Kagami's insides were, they were just gripping onto him, pulling him in deeper.  He parted from the kiss to look into his lover's face, "You're so damn hot."

Kagami blushed, he looked like he was about to say something but then Aomine pushed all the way in, rubbing right up against the spot that Kagami liked and Kagami was reduced to gasping and moaning.  Aomine started to move, staying deep in his lover, rubbing against the same spot each time.  Kagami was panting like crazy, unable to form words, even a bit of saliva falling from the corner of his mouth.  Aomine just couldn't get enough of the view.  But Kagami's insides too.  Aomine knew that it would feel differently than usual too and it felt amazing.  He wanted to stay so deep inside his lover.

They kept moving together, Kagami was going crazy from the pleasure.  He just couldn't hold back anymore.  He tried to warn Aomine, but it all just came out as a loud moan and he tightened down on Aomine.  It was enough to make Aomine climax too, releasing deep inside Kagami.  He stayed like that in Kagami for a moment until everything was released.  He pulled out and moved to lay next to Kagami.

Kagami was still panting and catching his breath, but he turned to Aomine, lust still clouding his eyes.  His voice was breathy and filled with want, "Ao~" he smiled, "Once more, please?"

[A/N: I hope you enjoyed this long part! I had to put it all into one and this was a lot! So I hope my sleep deprivation was worth it and that you enjoyed it!]
