When we got home, Holly ordered me into the bedroom and told me to take my clothes off. Our visit to Eva's home had gotten us both worked up and we both needed sexual release. She felt we should forego being coy or flirtatious and just get down to being naked and in bed.
Once I was fully naked, my sister eyed me up and down, openly admiring my breasts and exposed pubes. The way she looked at me made me feel even more naked than naked, especially as she was fully and decently clothed.
"Lie down on the bed," she ordered. "Face up, arms and legs spread."
"Yes, Mistress," I replied weakly. My voice was so soft and tremulous, I'm not even sure if she heard me, but I lay on the bed and I spread my body wide open, leaving myself vulnerable for whatever my sister had planned.
Then Holly placed leather restraints around my wrists. I moaned as my sister attached my wrist restraints to chains and then buckled restraints on my ankles as well. Within moments I was bound spread-eagle to my sister's bed. Then, she shoved a pillow underneath my ass, forcing my hips and pelvis to be raised higher and forcing my pussy to be even more indecently on display.
"Ooh, you've got me helpless and at your mercy," I moaned. "What are you going to do to me now?"
I reveled in my feelings of helplessness and vulnerability. My breasts and pubic lips were fully on display. Holly could whip them, like Mistress Lockley whipped Beauty in that Ann Rice book. An agonizing wave of desire passed through me as I envisioned what it would be like for Holly to whip me like that, but she had other ideas.
She crawled on to the bed and knelt between my widespread thighs. Then her tongue went to work on my pussy.
"O-oh,"
I moaned.
I gasped and whimpered. My sister mouthed my pussy, sucking, licking, nibbling, tasting me. I felt one spasm after another ripple through my body, and arched and twisted and rolled my hips in shameless, wanton pleasure.
I was right on the edge, when Holly got up from the bed and proceeded to strip naked. My sister was an intoxicatingly beautiful woman, and my first instinct was to reach out and take her into my arms, but of course I couldn't. It was a tease. One of the most beautiful women in the world was naked right in front of me and I couldn't touch her because I was chained down. I knew I couldn't get free, but I struggled against my restraints anyway.
The more I struggled, the more my feelings of helplessness increased. And my extraordinary feelings of helplessness fueled my feelings of sexual arousal. And just when the pulsing fire in my loins seemed to reach fever pitch, Holly laid her naked body on top of mine.
She pressed the front of her naked body into mine and then rubbed her body up and down, brushing her breasts across mine, getting my nipples even harder and more excited with the erotic friction she was creating. Being bound and helpless, it felt almost like rape or being sacrificed to some sort of pagan goddess. I moaned as tingly sensations spread all up and down and my body was suffused with sexual heat.
"Yes, you're my helpless, naked prisoner," Holly whispered seductively. "And I can do anything I want with you."
An inarticulate moaning sound escaped my lips and then Hannah covered my mouth with hers. She kissed me for a long, long time, her tongue probing, caressing, massaging my own tongue and transporting me into some sort of sex slave fantasy where the slave is raped by her mistress.
I felt like one of those big-bosomed damsels in the old black and white vampire movies. Instead of wearing a corset and a low-cut European peasant blouse, I was stark naked. And instead of a vampire sinking his fangs into my jugular vein, a domineering lesbian was leaving a series of love bites up and down my neck as I shuddered, moaned and gasped. My head reeled and I savored my role as the naked helpless victim.
After covering my neck with love bites, Holly explored my naked body with her hands and her mouth. She kneaded my breasts, before gently biting my nipples and then sucking on them. She took my breasts into her hands once again and brushed her thumbs up and down across my excited nipples, getting them so hard that they ached.
Then, she slid down my naked body and once again her face was in between my legs. I whimpered and strained against my restraints as I felt her mouth once more on my pubic lips.
"Ohhhhhh!"
Holly placed her hands on my hips and energetically licked my clit. My body was already thrumming with sexual electricity and my sister's tongue drove me to erotic heights I can't even describe with words.
Her tongue was working on my hard, swollen clit, and I gasped and screamed as I became overstimulated. My body wiggled and shook as my sister pried my pubic lips apart and sank her tongue deep into my pussy.
"Oh! Ohhhhhh! Aaahhh! Aaaaaahhhhhh!"
She placed her hands underneath my butt, cupped my buttocks and plunged her tongue even deeper into my pussy. I squealed as her tongue probed my moist interior. I strained against the restraints as her tongue skillfully wiggled inside me. I tried to thrust up to get even more of that enthusiastic tongue inside me, but the way Holly had chained me to the bed I could barely move. Even my most frantic struggles resulted in barely more than a writhing shudder of my hips.
I screamed and gasped and panted and then Holly sucked my hard sensitive clit into her mouth. I came against her face in a series of powerful spasms as I climaxed again and again and again.
When it was over, I savored the blissful afterglow of the powerful orgasmic release. Then Holly climbed up my body and straddled my head.
"Lick," Holly demanded. "And do it well. Slaves who fail to make their mistresses happy, get punished."
Talk of punishments worked to rouse my libido again, especially while I was bound wide open and helpless. I moaned, stuck out my tongue and my sister ground her pussy against my face.
I thrust my tongue up against Holly's pink slit, driving it between her pubic lips and working it into the mouth of her sex. I licked it upwards and located the hard, rounded swell of her clit with my tongue.
I began to lick Holly's clit as she rode my face and I got swept up in the fantasy and immersed myself in the idea that not only could Holly punish me if I did an unsatisfactory job at licking her pussy, but that she should punish me if I did an unsatisfactory job. After all, isn't that the primary reason for owning a slave? Slaves are supposed to keep their owners satisfied. I thought of that and put even more effort into driving my sister into orgasm.
