Hi. I'm Len Kagamine. If you're really imto the Vocaloid program, you might know who I am. I have a twin sister, Rin, and, boy, does she have a nice ass...oh, what? Sorry, I was daydreaming. As I was saying, Rin is my twin sister. We're 14 years old. We both have blonde hair, blue eyes, and, holy SHIT, I wanna squeeze them tits. Oh, whoops. I happen to get very lost in sexual daydreams of my sister.

Rin has a nice rack. About 32C. She has flawless, gorgeous blone hair that smells of oranges, and she has the pussy of a godess. Shaved, pink, and recently de-virginitized. I know because I did it. Heh-heh.

As for me, I have good sized blonde hair as well, and my dick ain't bad, either. It's about 8 or 9 inches long, and 2 inches thick. I bet all you housewives who have men with small dicks would want even a quicky with me, and make it, still, into something romantic.

Well, we're both about 5'4, and have a good sense of style.

Let me go back........

"Rin-Chan?" I called out. Earlier we were wrestling for the remote to the TV, having a good time, and, when we finally finished, I was on top of her, my hands pinning her arms down, and my legs on either side of her. I've always had this secret crush on Rin, and I saw this as the perfect opprotunity.

I leaned in to kiss her, and, halfway there, she asked me what I was doing, but I stopped her in mid-sentence and mashed my lips to hers.

She seemed shocked, and she pushed me off of her, and she ran into her room. At first, it seemed like she was crying.

"Rin-Chan,Are you okay? I'm sorry, I couldn't cont-" I stopped when I heard something coming from the other side of her door. It sounded like...She was not.

I pushed the door open and saw her fingering herself vigorously. I instantly felt a bulge in my pants as my cock started growing. Immedeately, I tore off my shorts and underwear and pinned her like before.

Here I was, sitting on top of Rin, dick hanging out and positioning myself over her dripping wet pussy. I aimed my cock at her love hole and pushed forward slowly.

"Len, what...oh, yeah. Oh, God, Len! Don't stop!" she moaned.

I pushed further in and felt something snap, then a scream came from Rin.

"Rin, are you okay? Did I hurt you?"

"It's okay," she said. "Keep going...It feels nice."

I didn't need to be told twice. I thrust forward once more, this time earning a well-pleasured moan from Rin, who was blushing furiously.

I started pistoning in and out of her tight cunt, all the while thinking "Is this really happening?"

-RIN'S POV-

He pushed his cock in and out of my soaked vagina while I just sat there and moaned. As this was my first rod, instead of my fingers, it was a sensation like no other. The feel of hos 8 incher plunging in and out of me, rubbing tightly against my g-spot, I felt tingly.

All of a sudden, while I'm enjoying the best sensation in the world, Len picked up the vibrator I was using, and started plunging it into my asshole. It was amazing! As I started to tweak my nipples, I felt that fun sensation.

"Oh, oh, ah, ah, ah, yes! YEA! Oh, GOD, Len! I'M CUMMMIIIINNNNGGGOOOHHHGOOOODD!!!! -LEN'S POV-

I was constantly pistoning in her cunt, and, as I saw her play with her tits, that sent me over the edge. She screamed in ecstasy that she had started to cum. "OH, holy shit! I'M CUMMING TOO! AAAAAAGGGHH!" We started cumming in sync, like twins would do and, once I finished, I pulled out.
