Daphne Phillips - Sinful Cyndi

I chuckled. "You bet," I said. "Mom and Dad fucked in this bed… and Dad came in Mom's slit…"

"Mom's slit," sighed Cyndi longingly. "It's so fucking sexy. And we just fucked in it. You just fucked me doggy-style in this bed. We just committed incest in this bed. Oh God."

I nuzzled Cyndi's ear. "That's great. We're going to fuck a lot more in this bed before Mom and Dad get back."

"And maybe after," sighed Cyndi. "I want you to… do things to me."

"What kind of things?" I asked her, whispering into her ear as I licked it.

"What would you think…" she began to ask me, but got nervous and buried her face in my chest.

"What baby? I love you, Cyn. I'll do anything for you."

"No," she said. "It's too dirty."

"What?" I stroked her back soothingly. "Tell me. Ask me. I'll do it, baby."

"What would you think if I asked you…" she paused, panting heavily into my ear. "Would you… would you put your cock in my asshole?

Would you fuck me up the ass?"

"OH God, baby," I panted, "I'd love to. I've been dreaming of fucking you that way…"

"Tonight?" she begged. "I want to think about it all day… I want to know that you're going to fuck me up the ass. Promise me you'll fuck me up the ass tonight?"

"I'll do it, baby. I'll beg you to let me do it!"

"Oh, God, yes, Ian," panted Cyndi. "I can hardly wait until tonight.

Let's get drunk together. We're going to spend all night together, nude in each other's arms. It's so sexy. We'll sleep in the bed where Dad came in Mom's pussy and conceived us. I can hardly stand it."

"Yeah, baby. I'll get some champagne – We'll drink it and get drunk and then I'll fuck you up the ass."

"Oh, brother. I love you so much… I'm so glad we're finally in bed together…"

"Me too, Cyn, me too."

I was indeed glad that my delectable sister Cyndi had seduced me. After all, I'd been dreaming about that moment for months now. The moment when I penetrated Cyndi, stretching her tight young cunt-hole with my cock and sliding my entire long shaft into her so she moaned in pleasure. And now I knew quite well that I would be doing it to Cyndi for some time to come. And to cum, certainly! Cyndi was the sexiest slut I had ever known and she was my own sister. Not only that, but she seemed to be in love with me. And I loved my sister very much. I would give her everything she wanted. What I wanted more than anything was to bone Cyndi till my cock was slick with her cunt-juices. Today's fucking had been more than my wildest dreams would have hoped for.

Cyndi held me in her arms and she dropped slowly off to sleep. I felt myself drifting too, and before long I was relaxed and groggy in my sister's arms. Cyndi and I slept together in the bed where we'd been conceived, our nude and sweaty bodies pressed together. Cyndi's heartbeat throbbed rhythmically against my chest, matching the rhythm, it seemed, in which we'd just fucked.

Cyndi and I lounged in the huge bathtub. Cyndi was turned on her side and lying half on top of me so that her firm tits rested on my shoulder. Her face was nuzzled against my neck. She kissed me every few minutes, touching my skin with her wet lips and sensuous tongue. Her hand lay in my lap, curved absentmindedly around my cock, which was quite hard despite the fact that I'd already cum twice. Cyndi was quite the tease, though-she just barely touched my cock, letting her thumb trail gently around the head under the hot water. The bubbly suds hid what she was doing, but since most of her luscious form was out of the water and on top of me, I could see many of the curves of her naked body. Cyndi sighed, kissing my ear.

"I'm so happy I finally went to bed with you," she whispered. "I've been wanting to feel your cock inside me for so long. I don't know why I didn't come on to you sooner."

"I've been watching you, too," I said. "Sis, you're one of the easiest girls to spy on I've ever seen."

Cyndi gasped in mock surprise. "You've been spying on me?"

"All the time. It's an obsession."

"What-what did you see?" She smiled as she looked into my eyes.

"I saw you doing some very kinky things with Rod. And those three other guys. And more than that I saw you changing your clothes and sunbathing a lot. You've got an incredible body-I couldn't look away!"

"Oh, I feel so violated!" Cyndi giggled. "Did you like what you saw?"

"I wouldn't have put my cock inside you if I didn't, right, Sis?"

"Oh, I don't know…"

I put my lips on hers and tickled her mouth with my tongue. "Sis, I love your body. And I'm tired of spying on you. From now on, I intend to see it from up close."

Cyndi sighed and put her arms around me, rubbing her soapy tits against my chest. "That's good," she said. "I'm going to be very close to you, with my legs spread. Anytime you want to spy on me, you just tell me, brother. And I'll do it for you-up close."

"I'd like to see you giving a hand job in the bath," I grinned.

"To my very own brother? You mean, committing incest?"

"Aw, it's not incest if I don't cum inside you, Sis. Isn't that right?

The incest taboo is just to keep the genetic lines pure. And you're on the pill, so it can't be incest, right?"

Cyndi giggled. "You think about this a lot at school, eh brother?"

"Anthro majors learn all about sex."

Cyndi sighed and kissed my cheek. "It's incest," she sighed. "That's what turns me on so much. I'm in love with my brother, and I can't stop wanting to fuck him. Put his cock in between my legs." Cyndi panted rhythmically as she spoke.

She slid her hand down on my cock, slowly caressing it with her soapy fingers. Her breathing quickened as she ran her thumb over the head and tightened her fingers around the shaft. I grunted in approval as my sister began to jerk up and down on my cock. She pressed her lips against mine and started french-kissing me deeply, nibbling at my lips and tongue and suckling at my mouth. She let out a whimper as I dropped my hand to her ass and kneaded her smooth buttocks, spreading them slightly. But Cyndi didn't slow down or ease up pressure on my throbbing, hard cock. She kept jerking me off.

I breathed slow and heavy into Cyndi's ear as she manipulated my cock up and down. She started bringing it around in smooth, slow circles, sending shivers through my naked, soapy wet body. Cyndi squirmed on top of me, pressing her own nude form down against me. Her breasts slid rhythmically against my flesh, we were both so covered in soap that we were incredibly slippery. Even so, Cyndi managed to keep a good grasp on my cock, jerking me off in circles. She knew just how I liked it- that's what I did when I jerked off myself, like when I was watching Cyndi, which was often, believe me! I wondered if she'd watched me herself-after all, the door to the bathroom was frequently open or ajar, and I lay on my bed with my legs spread and my cock in my hands.

Or maybe Cyndi was just so attuned to her big brother's cock that she knew what I wanted instinctively.

Cyndi's hand moved in bigger and bigger circles, grinding against my cock. She moved my prick like it were the crank on a generator building up a current of desire. I squeezed my sister's ass-cheeks tighter, bringing her up and down as she played with my prick. She whimpered as her gorgeous body bounced up and down on top of me. I grunted in time with her cock-jerking as Cyndi lifted her head and stared into my face.

"I want you inside me," she panted. "I want you to cum inside me again."

I nodded, out of breath from the intensity of fighting off my orgasm. I didn't want to cum yet. I wanted this sordid, incestuous tryst to last as long as possible before I shot my load into Cyndi's hand. But now Cyn was begging me to fuck her again-and I certainly couldn't say no to my sister!
