"OH GOD IAN!" she screamed. "I can't believe it. It's so good, brother, I love it." She turned her head and stared right into my face with those big blue eyes. "Put it all in. Put your whole cock inside me.
Promise me you'll put your whole shaft in there."
I nodded. "I will, Sis. I will, baby."
Cyndi groaned as I eased my cock into her. She felt the long shaft stretching her cunt, opening it up for the whole length. I held her hips tight, my thumbs pressing into her buttocks. I made sure Cyndi was steady as I entered her.
Cyndi let out a shriek as she felt my cock settling all the way into her. I know from all the women I've fucked that my cock is bigger than most guys-and my sister Cyndi's cunt is tighter than most womens'.
That's why it felt so good to have my cock shoved all the way up Cyndi's tight cunt-hole. Her pussy lips gripped my long cock shaft with as much force as I could want. It seemed like her heartbeat massaged my cock as I slid it into her. Grunting with pleasure and exertion, I began to drag my cock back out of her-just far enough to shove it in again!
"OH, Oh YEAH!" moaned Cyndi as I rammed my cock into her tight cunt once more. Cyndi whimpered in ecstasy as I began boning her quickly, working my cock in and out of her cunt. She writhed and quivered with pleasure. Her whole body was flushed from the exertion of giving me head and taking my cock up her cunt as well as the desire to have me fuck her. Cyndi was amazing-she seemed to shudder with each thrust I gave her. She moaned and writhed and bit her lip as I shoved my cock into her. She was really turned on and hot for my shaft. Cyndi began to whimper every time my cock-head sank to its deepest point in her warm wetness. She groaned as I penetrated her again and again. I fucked her doggy-style, holding on to her hips and her ass-cheeks as I boned my cock into her. Her cunt felt so good around my cock that I couldn't believe I'd waited this long to fuck my luscious sister. I watched Cyndi's gorgeous ass bobbing up and down with the rhythm of my cock going into her. Her asshole looked tight and delicious. I knew before long Cyndi would ask me to enter that way and I'd gladly oblige, finally finding out what Cyndi's asshole felt like from the inside. I groaned as I shoved my cock into Cyndi. She was going crazy, panting and shuddering with pleasure as I entered her. Cyndi looked back at me, her eyes wide and her lips parted, begging me to fuck her harder. I summoned up all my energy and started pounding my cock faster and faster into Cyndi's snatch, but I knew that before long I was going to cum!
The thought struck me that I was boning my own sister doggy-style. I couldn't believe how kinky this was. And I was about to cum in her snatch. I was very glad Cyndi was on the pill. I'd hate to explain this one to Mom. Of course, maybe Mom understand-after all, we were doing it in her bed…
"Oh God, Ian… Ian… oh God, that feels good!" Cyndi began working her snatch up and down in time with my cock, meeting every thrust of my hips with one of her own. "That's so good… fuck me… hard… deep … It's so good…. Keep doing it… I'm going-OOOOAAHHHHH…"
Cyndi groaned as she got ready to cum. I watched her face twisting in ecstasy. Cyndi was the most beautiful girl I knew, and here she was cumming while impaled on my long shaft. As a matter of fact, she was going to make me cum at about the same time she did. I was getting very close!
"Uh…" I groaned. "Cyndi… Sis… I'm gonna cum in your pussy."
"Do it," she whimpered. "Spurt into me. I want to feel it. Please, Ian.
I need your cock."
"Oh God," I panted. "You're so good… your cunt…"
"Yes, baby, cum in my pussy. I want your cum. Spurt for me!"
I rammed by cock faster and faster into Cyndi's pussy. Cyndi shoved her ass quickly up and down on my cock, impaling herself again and again on my long shaft. When she realized that I really was going to cum in her, she let out a moan and then began to quiver in delight. As I felt my cock throbbing and swelling with near-orgasm, Cyndi's cunt contracted in rhythmic spasms of pleasure.
"Oh, God, Ian… you're making me cum! I'm cumming… you're making your baby sister cum. Make me cum. Fuck your baby sister," she panted.
I felt her shuddering in ecstasy, orgasm flooding her body quickly as she lifted her ass and thrust it down hard so that her cunt swallowed up my cock every time. I watched Cyndi going wild with her climax-she was mad for my cock!
Cyndi slumped forward on the bed, letting her big brother fuck her rapidly and increase the intensity of her orgasm.
"I'm cumming… cumming… cumming… uh… uh… uh…" she panted rhythmically as she quivered in pleasure. Then, with hard thrusts into my little sister's tight snatch, I began to cum.
"Oh God," I panted. "I'm cumming inside your… your… pussy… it's good… good… yeah… fuck me."
Cyndi's cunt felt so incredible around my cock. My prick jerked up and down in orgasm and I felt it spewing out a thick stream of jizz into my sister's wet slit. She was whimpering and begging for more in pleasure as she felt me put it into her again and again. Cyndi was crazy with desire. Her whole body was quivering as I boned her. My cock seethed into Cyndi's snatch rapidly as I spurted into her.
I could feel my cum dribbling out around my sister's thick, lustswollen pussy-lips. As the cum formed in droplets and ran down onto our parent's bed, Cyndi pressed her tits against the sheets and stretched her arms out, prostrating herself so that she lay there passive and just took the thick streams of cum from my prick-head. When I was finished cumming, I slumped forward on my sister's nude body and pressed my lips against her sweaty neck.
"Oh God, Sis. Your cunt is so good. I can't believe what a good fuck you are."
Cyndi eased herself out from under me, tugging her cunt away from my cock so that I left her quickly. She put her arms around my shoulders, lying on her side and facing me.
"You're going to fuck me a lot," she sighed. "Now that I've got your cock inside me, I don't ever want it out of there. I want you to fuck me all the time."
"I'll fuck you as much as I can, baby."
Cyndi leaned heavily against me, her face against my chest. "I've been dreaming of this for a long time. brother. Now we can take a nap together… in this bed. We were conceived in this bed. We were conceived in this bed, honey isn't that sexy?"
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?"
