/WARNING/

LEMONS FLYING EVERYWHERE.

Karasu: The sound of love and lust echoed through the Kagamine twin's bedroom in the middle of the night. The other vocaloids were on vacation till who knows when,leaving the two twins to do whatever they want.

"Nn-Rin..Your sucking too hard..." Len panted as he came in Rin's mouth, cum splattering everywhere.

"L-Len's..j-juice.." Rin slurped it all up,enjoying the taste of the warm liquid.

He blushed at the sight of Rin slurping up all his cum. " R-Rin you know that you don't have to do that right?"

"Ha..ha.." Rin's face was a dark shade of red. "B-but..you tasted..really good.." She closed one eye seductively as she licked the extra cum off her fingers.

"R-Really? Do I taste that good?" He stared at the sticky looking liquid on Rin's face. "T-Then would you like to taste me more?"

"B-but..I want Len to taste me too.." The blonde leaned in closer to her "brother" as she kissed his jawline, teasing him

"O-Okay..If you insist..." Len slowly slid his hand into the back of Rin's panties. He pulled it down to her knees,enjoying the contact between his fingers and her skin while kissing her forcefully,his tongue sliding up and down in her mouth skillfully.

"m-mnhh.." She moaned as his tongue came into contact with hers. He explored the insides of her mouth. Her legs were trembling slightly as he pulled down her light pink laced panties.

"I can taste myself..." He chuckled. "But..I wonder what does Rin taste like?" He slipped off her panties and threw them behind him. Grabbing her thighs,he bent down and started to lick the area around the opening of her clit.

"A-ah..~" Moans of pleasure had escaped her soft pink lips. She held onto Len's head as he began to lick and suck on her.

He started to increase the speed and strength of his licks while toying with her by thrusting his tongue in and out of her.

"L-Len! Ah!" The pace of her breathing was slowly increasing with the constant pants and moans she let out.

"Mm..Rin" He nibbled on her as he rubbed her thighs which were wet with perspiration,making her shiver.

She let out a rather loud gasp as her juices splurged out.

He moaned in glee as her juices overflowed his mouth, the rest splattering all over his face. He gulped it down,licking his lips gleefully. "Rin tastes delicious too,better than me in fact."

"D-don't say that..." She blushed and looked away.

"B-But its true..Here..taste it yourself.." Len sucked up the remaining cum dripping from Rin's opening and fed it to her,their chest in contact.

She opened her mouth and tasted herself hesitantly. She then started to suck on his finger

"Nn..." He moaned in delight as he felt his fingers being enveloped in the warmth of her mouth.

"I-I'm ready, Len.." She smiled at him sheepishly before climbing on top of him.

"Ready for?" Len pretended to act confused,knowing what she wanted.

"Idiot..I'm ready..f-for you..to be..I-inside me.." She blushed beet root red as she lowered her head trying to cover it. She positioned herself,spreading her thighs apart as she moved up to his pumping cock. It was rubbing against her folds. She gasped softly as she felt a slight form of pleasure from it.

"Ah..How cheeky of you.."He grinned as his dick was slowly being inserted into Rin. Grabbing her waist,he pulled her closer to him and at the same time thrusted forcefully into her.

"Ahh! Len..it hurts..it's my first time.." She said as tears formed by the side of her eyes. But, she still continued to slowly move up and down his length. Her pain soon fell to moans of only pleasure. "M-more Len! Faster! Faster!" She begged for more from Len. She entwined her fingers with his.

"Y-You're so tight Rin...Relax a little...Its my first time too...A-Ahhnnn.."Len groaned in pleasure as he felt Rin's muscles contracting,squeezing his cock. He started to thrust into her at a faster speed,enjoying her moans of pleasure that was getting louder by the second.

"L-Len! I'm gonna..I'm gonna.." she managed. The room they were in was getting steamier, the room was filled with lust and love, there was finally no one to interrupt or stop them. She leaned over Len, already at her climax. "Aaahh!~" she let out a long moan of pleasure.

Len's body was starting to ache from thrusting into her and his vision was starting to get blurry from the heat,but he had no intention to stop. "B-Bear with it for a little longer Rin..." He mustered up all his left-over strength and kept thrusting into her at full force.

"Len..Faster...h-harder..I-I want all of you..." She smiled weakly as she looked into Len's blue glassy eyes that were full of lust.

"T-This is the fastest i can go.." The friction between his dick and her vagina was unbearable,he bit on his lip,trying to hold his cum in. "I-I..Hnn..A-AAHHNNN~.." Sticky warm juice spulrged out from his hole,he stopped thrusting into Rin,filled with embarrassment. "H-How could I..I couldn't hold it in longer than you..."

"I let mine out a long time ago..it's okay Len..it f-felt really g-good.." She giggled innocently. "Tomorrow's our birthday" she whispered to him.

"B-But i d-did it...twice.." He stared at his juice,it was slowly oozing out of Rin's clit. "A-Ah..It's in you..I'm sorry.."

"It's okay Len...I'll make sure you'll have the best birthday tomorrow" she smiled at him as she cuddled up to his shoulder and slept.

"M-Me too.." He licked off the remaining cum off his lips and kissed Rin on the forehead. "I'll make sure you won't be able to sleep."

She knocked out before he could finish his sentence.

Len turned around and glanced at the "tools" which Kaito gave to him before closing his eyes and falling into a deep slumber.
