Nothing better than waking up next to a beautiful girl.

Waking up in the morning is a struggle. You're warm and supremely comfortable, moreso than you can remember in a very long time and both your body and mind want to revel in those feelings for as long as they can. As your eyes slowly open, the reason for the warmth becomes immediately clear.

During the night, you and your sister moved into a spooning position, with her smaller but curvy body fitting perfectly into your longer, lankier one. Your arm is tossed over her side and rest lightly against her stomach in a soft embrace that has pulled her cute little butt against your crotch. She looks even more beautiful this morning, even though her hair is mussed from sleep and day-old make-up covers her face. Her skin still feels electric beneath your fingers and as you take in her nude form, remember the magical night you experienced with her, your cock begins to stir and rises gently until it presses deep into her buttcheeks. I doubt she'd be against a little morning delight, you think with a grin.

You raise your hand to her big titties, silently and carefully exploring her silky slopes while she continues to slumber. They had been great before you dream-enhanced them, but now they're probably the best pair you've ever seen--and definitely ever felt. Soft and pliant, your fingers sink into her flesh with ease but, largely due to her youth and stringent yoga routine, they've retained a pertness that keeps them high on her chest with little sag. Soon, her nipples begin to harden, giving you another target for your teasing, and the playful twists you give them are finally too much for your sleeping sister.

With a contented sigh, Shelly opens her eyes and turns her head until she can see your devilish smile. She smiles back and settles into your body, delighting in the feeling of having you beside her, pressed against her. You lean forward and kiss her deeply, her lips opening wide and her tongue meeting yours eager.

When you break apart, she says, "Someone woke up horny this morning." She wiggles her ass, twisting your sensitive erection back and forth, giggling like a naughty little girl. "I'm a little surprised given the number of times you came last night. Plus there was that perverted little dream you gave me. You know, the one where you fucked me like a whore in front of Daddy while Mom and some other girl watched. God, that was fucking hot! By my count, you came four times...and you're ready to go again this morning!? Lucky me!"

You laugh, amazed once more at how slutty--in a good way--your sister has turned out to be. You tweak her nipple, making her gasp erotically, and nibble at her bare shoulder.

"First," you say around a mouthful of shoulder, "the dream orgasms don't seem to count as much as they do in the waking world. And second, you're the sexiest nymph I know and you've been giving me hard-ons ever since these puppies started making an appearance. Now that I've got unlimited access to your hot body, I'm not going to ever pass it up."

A slightly crazy twinkle flashes across her pretty blue eyes and she arches an eyebrow. "So you're saying that we could have a fucking orgy in our dreams, fuck and suck all night long, have orgasm after orgasm, drown me in your delicious cum...and you'd still wake up with a giant piece of lumber for morning wood?"

You nod and suddenly she's kissing you again, her hot lips driving against you with such **** that you literally lose your breath. You feel her body shift slightly higher and her thighs part until your dick slips free, resting against the blazing furnace of her pussy. It's already wet and slippery. Shelly finally comes up for air and says, "Like I said, lucky me! Now stuff me with your fat piece of meat and make me scream your fucking praises."

Not one to disappoint a lady--especially a lewd, horny fuck-bunny like your sister--you slide your hips forward and let your fat tip split her eager cunt lips. As you push deeper and deeper inside her twat, your sister shudders with an audible groan, lifter her leg higher to give you a better angle. With one final thrust, you're once again balls deep inside your sweet Shelly, the joining between you a piece of blissful ecstasy. "Oh, yes!" she cries, lust taking control of her voice.

This fuck session with your sister lacks some of the taboo from your first round last night and the animalistic pleasure of the assfucking you gave her, but you both make up for it with the passion you put into your movements. Your movements compliment each other perfectly, like a couple who's been together forever and know all the intricacies of their partners body and desires. As you push forward, your sister rocks her ass back to meet you, ensuring that your sliding as deeply into her sweet pussy as possible, stretching her with your thick rod until she's shaking like a leaf.

"Oh, big brother, my love!" she pants breathlessly. "Your dick is driving me crazy, filling me up sooooo fucking good, you're so big and hard! Don't stop, don't ever fucking stop! Just keep banging me forever, I love you so much!"

She folds her hand atop yours and brings them both to her jiggling boobs. She mashes them down and wordlessly urges you to maul her juggs forcefully, never stopping her grinding and gyrating as you screw. Once again, her head turns and she pulls your lips to hers. With three points of contact with your gorgeous sister--mouth to mouth, hand to tit, and cock to cunt--your blood boils three times as fast as before and, despite your best efforts, you can feel your balls begin to churn.

You warn Shelly about the imminent gift she's about to receive and she shouts, "Me too, me too! It's okay, pour it all into my womb!"

You do just that, bearing down on her giant breasts so hard that you leave red fingerprints on her ivory skin. Her body is rocked by her orgasm, her shaking increasing as she hits her climax and for a while, you both lose control and let your twin releases bloom until nothing else matters.

It's a full two minutes before either of you regain enough composure to speak. Now that your primal urges have been taken care of, you bring up a topic that's been marinating in your brain since last night. You cuddle close once more, enjoying the simple presence of her in your arms.

"Did you mean what you said last night?" you ask.

Her brow furrows. "You mean about you being the first guy to have my ass? If you weren't convinced by how tight I was, I'm not quite sure how to convince you." Her mouth quirks up in a naughty curve that you find incredibly hot.

You chuckle and shake your head. "No, I mean the thing you said while I inside your butt. The part about being my whore, my slut and a couple of other perverted roles...and about me fucking other women."

Shelly shifts in your arms, turning around so she can face you. She waits until your eyes stop watching her boobs settle into place and then answers with mock seriousness on her face. "We just had very hot, incestuous sex where you unloaded a boatload of jizz in my pussy and you're already think about having sex with other women?"

Her teasing tone makes you both laugh, but then she gives a tiny shrug and rests a loving hand on your cheek. "Honestly? The idea bothers me a little bit. What I shouted last night was kind of in the moment and the situation was driving me out of my mind. But...." She pauses to collect her thoughts, biting her lower lip. Goddamnit! Why does everything she do look so goddamn sexy!? Then she continues in one breath.

"But I've always been a bit submissive sexually and so the idea of being with a dominant personality, someone who not only makes me bend to his whims but other women as well, is a big turn on. Especially since I'm kinda...bisexual." Those words make your loins, sore from all the recent sex, ache sweetly. "If you hadn't guessed, Scarlett has always been a little bit more than a friend, which is another reason why I recommended her as your beard. The thought of the three of us together on this bed, both of your mouths on me...." She shudders again and you feel your own nether regions on the rise again. It takes minute for her to compose herself. "So, I guess what I'm saying is...as long as you keep coming back to me, continuing to love me as much as you do...I'm okay with you having sex with other women."

You can see that Shelly is still bothered a little by the thought and you love her even more for her courage in making her decision, her confession. You lean forward and rest your forehead against hers, your noses almost touching. "Tell you what," you say, "How about we make a deal? Before I have sex, or do anything with another girl, I get your approval first. How does that sound?"

A simple smile alights Shelly's face and you can feel her snuggle closer to you. "That sounds perfect," she says, relieved. "You really are an amazing brother." She purses her full lips and then nods to herself, as if finally coming to a decision. "And since you're being so magnanimous, I'll give you a concession as well. Our deal is only for the waking world. When you're dreaming, you can live out any fantasy you want, with whomever you want, without any repercussions. After all, isn't that what dreams are for? Fair?"

"Fair." You seal your bargain with a kiss.

"Good," she replies and tilts her head down, her hungry eyes finding the beast that has reawoken and is currently trapped between you. "Now, what kind of girlfriend would I be if I kicked you out of bed with your big, delicious cock still looking like that? Lay back and let me take care of that bad boy."

She pulls away from you, crawling to her hands and knees, her heavy breasts swinging freely and you whistle in appreciation. She shakes her head shamelessly and, starting at your chin, begins leaving a trail of kisses down your body, slowly running her lips and tongue against your finely formed muscles. By the time she reaches your crotch, you're at full attention and enjoying the hell out of watching her naked body writhe and shimmy closer and closer.

Shelly gives a few exploratory licks, her eyes locked with yours as you place your hands behind your head, letting her treat you like a king. Her tongue is masterful as the layers your shaft with saliva, reaching every nook and cranny before lifting her head back to the tip. She opens her mouth and sinks down. You watch her baby blues staring directly at you face the entire way down, taking you deeper than she's ever done before--not quite all the way to the root, but close--before gagging slightly as you nudge into her throat.

It's at this precise moment that the door opens and your mother walks in.
