Serving My Sister VIII: Pandora's Box

*** Sorry for taking so long to post this one, but I had hit a bit of a writer's block. Anyway, enjoy...
*** Note : This story is fictional!

I can still remember how this whole thing started, clear as day. Eileen, my younger sister, had caught me cross-dressing in our mother's clothes. From there, it was simple blackmail: I become my sister's sissy slave, she doesn't out me to our parents.

But somewhere along the line, things had changed. I still served her, true. But now I enjoyed it. Also, my mother was fully aware of the situatio, turned on by it, and was secretly fucking me behind my father's back. Considering the new direction the situation was headed, Eileen decided that it was time to take another turn: telling my father. The problem was that I was not made aware of this move in advance.

It had happened on a cool, fall evening. After arriving home from my final class of the day, my sister instructed me to head to my room, put on something sexy, and wait.

"Wait for what?" I had asked, feeling compelld to know.

"Trust me, you'll know," was all Eileen said to me. I wasn't even fully changed yet when Eileen summoned our parents to the living room. Curious, I left my door slightly ajar so I could hear the conversation. Mother played her part well, as Eileen laid it all out, acting as if it were news to her. Father was pissed--but there was something else beneath his anger, something I couldn't identify.

Knowing the jist of the turnout, I quietly closed my door and finished changing. I wore black panties of a split design--lace in front, satin in the rear. The matching satin and lace bra was brand new, thus its cups needed no stuffing. I covered my legs in thigh high, black opaque stockings, but decided against any garter belt this time. Finally, I donned my most appetizing chinese-style dress. It was black with silver seams, and each side of the dress's skirt had a split that reachd my hipline. Matching my outfit as my silver wig, that fell to the arch of my back and bangs coming to my eyebrows. Also, the wig was made with glitter in it, so it wouldn't be mistaken for gray.

I had been waiting for quite a while when something finally happened. My mother, I knew, would be out with her friends by now, as my father came into my room. He closed the door softly behind him, gazing at my body with lustful eyes. Eileen mut have known this would happen.

"Wow," my father said softly, as if worrying someone would hear. As for myself, I was frozen and speechless. "You look better than your sister." Without waiting for a reply, my father approached me slowly and eased me onto my bed (sitting, not lying). He opened his jeans and lowered them along with his boxers. I knew what was next, and should not have been surprised, but I was still a bit nervous.

"What're you waiting for?" my father asked me impatiently. As if jolted back o reality, I took his waiting cock into my hungry mouth. It didn't take him long to become fully erect, and he was so big that I had room to stroke him as well. I did so with one hand, and stroked myself with my other.

"You like that, don't you?" my father teased. "Like how it tastes?"

"Mm-hmm," I managed, his cock still pumping my mouth.

"Cum for your daddy. Fill the panties I know you're wearing."

And I did just that. As my father unloaded into my mouth, I too began cumming. Soon there was cum dripping down my thighs, between my fingers, and from the corners of my lips. I gasped for air when my father finally pulled out, but he apparently wasn't finished. He pushed me back into a lying position, and reached under my dress through the slits, grabbing my cum-filled panties. Roughly, he pulled them off and ordered me onto all fours. In position now, my father lifted the back of my dress and rubbed my cum all over my asshole.

Lubricant.

Still fully erect, my father pushed into me, his body slapping against mine. I nearly screamed with ecstasy, but daddy warned me to stay quiet. The next thing I knew, I felt his cock jump and another hot load fired into me. I couldn't help but cum again as well.

With me bed and my dress a creamy mess, my father gave a few final thrusts to make sure he was done before pulling out. "By the way, not a word to your mother."
