“There was a mix up with the cabins and we only have two bedrooms so you and Chris will have to share one,” your mother explains, looking frustrated by the mix-up; she rubs the bridge of her nose in annoyance. Your parents had rented a cabin at a lake for a family Christmas vacation, but the company booked the wrong cabin, leaving you with two bedrooms instead of three.
Your heart races with happiness. You've been fucking your own brother for months now. Yeah, you know it's fucked up, but damnit! He's perfect and he fits inside you so well! You both tried to tell yourselves it would never happen again after the first time, but neither of you could keep your hands to yourselves anymore. “Oh…whatever,” you reply, trying to be nonchalant about it. You flash a quick glance over to Chris who's trying to hide the fact that he's already fucking you with his eyes. He picks up his and your bags to bring them to the bedroom you'll be sharing.
“Your dad brought an air mattress so you can both have your own bed. I trust you two can decide who gets which,” your mother adds as she decorates the Christmas tree. You and Chris quickly exchange a knowing glance, knowing you'll not only be in the same bed, but you'll probably have his dick inside you all night, too. Your pussy tingles and throbs at the thought. After dinner, you all watch a movie as a family then all decide to go to bed early and go ice fishing tomorrow.
Chris locks the bedroom door after you're both inside, grateful the room is on the other side of the cabin from your parents. He backs you up against the wall, crashing his lips onto yours. His hands grip your waist, holding you in place as your tongues dance together. His hand comes up underneath your shirt to squeeze your pert breasts. He growls in approval, pressing himself harder against you. You feel his thick erection pressing on your lower belly, making your cunt throb and leak slick. Your moan vibrates into his mouth as the kiss deepens.
“So ready for big brother's cock, aren't you, baby sis?” His large hand slides down your body to cup your sex over your shorts. “Gonna breed this sweet pussy all fucking night,” he growls against your lips, “keep you full of my cum.” He leans his head down to suck on your neck and nibble your ear lobe.
You whimper and whine, unconsciously thrusting your hips against his hand, the heat from your dripping, wet sex rubbing deliciously against it. “Want it…love you so much, big brother,” you moan. Your fingers tighten further in his hair.
Chris smirks smugly against your supple skin. “Love you, too, baby sis. My sweet, perfect girl. Best fucking cunt in the world. Got me so pussy whipped,” He admits with a chuckle and continues to grind against you.
You let out a guttural moan, his ministrations pushing you closer to the edge of euphoria.
“Don't be too loud, little sis. I know Mom and Dad are across the cabin, but it's not that big,” Chris teases. His hand slides down into your panties beneath your shorts. “So fucking wet.” Fingers stroke and rub your soaked folds, tingles of pleasure shooting through your entire form. You try to stifle your moans, keeping in mind how critical it is that your parents don't find out what their son and daughter do to each other.
He silences your erotic noises with another searing kiss. Your tongues battle for dominance, saliva leaking onto your chin. His thumb continues to circle your swollen nub, tightening the band in your belly and bringing you closer to oblivion. Two fingers slide inside you, curling and brushing against your sensitive, spongy center. “Ohhhh,” you moan, bolts of pleasure firing through you.
“Cum for me, baby sis,” Chris demands in a growl, amping up his ministrations on your trembling body.
You hyperventilate as your orgasm begins, a tidal wave of ecstasy washing over you. Your pussy vice grips his fingers, sucking the meaty digits deeper inside you. He crashes his lips to yours once again, claiming your mouth. You ride the aftershocks on his fingers, still thrusting into you. When you finally come back down, he withdraws his hand and brings it to his mouth, licking his fingers clean of your cum. “Mmmm, fucking delicious, little sis.” He reaches down to undo his pants, pulling his throbbing, hard cock free. “On your knees, baby girl.”
You lick your lips and slowly lower yourself to the ground, your knees settling on the soft carpet. Staring into his eyes, you stick your tongue out and give a featherlite lick to his cock, precum hitting your tastebuds. Chris’ head falls back, the sensation of your tongue lightly kissing his shaft already sending him into the stratosphere. He growls hungrily, his fingers lacing into your hair as he fights the urge to thrust himself into your waiting mouth. “Fuuuuck,” he groans. You decide to tease him further, licking a long stripe up his thick, veiny shaft followed by a chaste kiss to his leaky tip, smearing his precum onto your soft lips. You give him a few more languid licks and light kisses then drop your mouth open to take the large appendage into your warm mouth.
Chris takes a sharp gasp of air and lets out a broken moan. “Yeah…that's it baby girl…suck big brother’s cock like a good little slut…fuck…gonna fuck your perfect mouth, little sis.” His thick fingers rake into your hair by your temples, holding your head still. His hips thrust back and forth, cock brushing the back of your throat. Your moans send pleasure inducing vibrations through the hard dick in your mouth. Your eyes cross as your own arousal builds inside you. Your hand slides down your belly and you begin rubbing your swollen clit.
More precum drips onto your tongue. He stops abruptly, pulling his thick length free. He lifts you up and places you onto the bed on your stomach. His rough hands grip your hips, pulling your ass into the air. “Mmm, perfect little ass…” Chris comments and gives your pert rear a light swat. He grips his rigid cock, sliding it between your legs, and slaps it against your wet cunt. “Beg for big brother's cock, little sis,” he taunts as he rubs your slick juices all over his hard length.
“Please! Please Chris! Need you! Need you inside me!” you willingly beg, rolling your hips back against his, feeling his magnificent dick glide between your folds, kissing your clit ever so softly.
“Hmm. Maybe I'll just enjoy a nice pussy job,” he replies with a mean laugh. He continues to thrust his cock in between your pussy lips but never moving inside. You try to turn around to protest but he presses your back with his hand between your shoulder blades, pinning you to the mattress. “Nah ah, baby sis. Big brother's in charge here.”
Your pussy clamps down on nothing at his dominance. “Chris! Please! Don't tease me! Please please I need you to fuck me!” You beg.
“Alright, little sis,” he purrs, “since you asked so nicely…” He lines his tip up with your quivering entrance and eases inside, an intoxicated growl escaping his throat. Your tightness envelopes him, moans dripping from your lips as you feel that fullness only he can give you.
You bury your face in the pillow, biting it with your teeth and muffling the sounds you wish you could make but don't want to risk waking your parents. You rock your hips back, meeting every thrust.
“Fuck yes,” Chris whispers sharply, delivering a slap to your ass, “Gonna breed this tight little pussy tonight.” He emphasizes his promise with a particularly hard thrust, his dick rubbing your sensitive g-spot. You cry out into the pillow. His grip on your hips tightens as the thrusting grows more unhinged and erratic. Your breasts rub against the bed, the soft fabric of the sheets brushing your sensitive nipples. He reaches around to rub your swollen clit, determined to bring you both over the edge together.
“Fuck, baby sis, that's it! Cum on big brother's cock!” Chris growls, continuing his sweet torture of your clit. You scream into the pillow as your walls contract around his dick. He doesn't let up on his thrusts or his rough circling on your pudgy bud. The excess stimulation is enough to bring you even higher, your slick essence gushing all over Chris’ cock and trickling down his legs.
He throws his head back with a groan, thrusting hard and pulling your hips against him as he buries himself deep, cumming hard inside you, shooting his hot load into your womb. “Ah fuck…”
You collapse onto the bed, panting, feeling his cum oozing onto your thigh. Fucking hell, you'll never get enough of this. Merry fucking Christmas.
