There was a soft knock on Micki's bedroom door followed by a whispering voice that asked, "Hey sis, are ya busy!?!" Micki put down her history book and replied, "Come on in, Mike, I'm just studying for quarterly final, what do you need!?!" Mike plopped down on the edge of Micki's bed and without even blinking, slid his hand up and under her bathrobe and began caressing the inside of her smooth thigh!!! "Hey, dummy," she whispered hoarsely, "what if mom or dad comes in, you wanna get us in trouble!!!" He chuckled quietly under his breath and replied, "Don't worry about a thing, they're already in bed fast asleep," while his fingers worked their way up her thigh until they encountered her panty clad pussy! 

"Well just the same," she retorted, "we made a deal that unless we were alone, we wouldn't take any chances!!!" I know, I know," he replied softly, " but jeez louise, just look at this," while standing up and opening his own bathrobe revealing a very firm erection!!! Micki looked at the door one last time, and making sure that neither of her parents were about before lowering her mouth to her twin brother's long fat cock!!! "Oh god, sis," he moaned, "you suck better than any girl I've ever had, I wonder which side of the family you get it from!?!" "She let his big pecker slip from her mouth before replying softly, "I don't know, but I'll bet it's from mom, I just think she loves sucking cock as much as I do!!!"

Mike stared down at his sister while she gently mouthed the head of his cock with her silky tongue and thought what a lucky guy he was to have a sister who loved sucking his pecker as much as he loved having it sucked!!! With her short blonde hair and compact swimmer's body, Micki was a wet dream come true!!! Her pert nipples seemed to always be standing at attention, acting like an open invitation to be sucked on!!! While they were only eighteen, both of them had an unbelievably heightened sense sexuality that required at least one orgasm a day, preferably induced by each other's warm mouth!!! Mike's head rolled back an forth on his shoulders while nearing his climax, and while a lot of women would like to be warned of an impending ejaculation, Mike smiled to himself safe with the knowledge that his pretty sister was desperate for a mouth full of his cum!!! With his knees buckling slightly and his cock stiffening perceptably, Micki groaned loudly as Mike filled her mouth with a load of hot burning sperm which she hungrily swallowed down as if it were nectar from the gods!!!

"Jesus christ," he panted, "someday you're gonna kill me when you do that, but what a way to go!!!" Micki just laughed that sweet lyrical laugh of hers that sounded a lot like wind chimes and offered, "Well, brother dear, you have such a beautiful cock I just can't help myself!!!" "Do you want me to do you," he asked thickly!?! "No," she replied, "let me use my dildo and you can jerk off watching me, I really feel like getting fucked tonight, do you mind!?!" "Mind," he sighed, "are you kidding, you know how much I love seeing you fuck yourself!!!" With that, she quickly slid off her white cotton panties, and after lying down on her back with her legs spread wide apart, she slowly pressed her thick black latex cock deep into her dripping wet pussy!!! "H-holy maloney," he gasped while fisting his meat and staring at the thick black invader sticking out of her smoothly shaved cunt, "y-you exactly how to drive me crazy, don't you!?!" As she slowly began fucking herself with short even strokes, she replied, "Do you know what I've been thinking about doing!?!" "What," he replied as his eyes began to glaze over, "t-tell me!!!" In a very sweet an syrupy voice she replied, "I've been thinking about going to school with my dildo stuck up my pussy, just think about that, me walking around school all day with eight inches of black cock jammed into my cunt!!!" "Are you really thinking about doing it," he gasped as his hand literally flew up and down his rock hard shaft!?! "Uh huh," she said with a little moan, "why, don't you think that would be a good idea, I mean, you know, having this big black cock up inside me all day!!!" "D-do you think you'd be able to cum," he croaked barely able to contain himself while picturing his pretty sister with the big rubber dick being held in place by her tight little panties!!! "Of course I'd be cumming, you silly boy," she sighed as her climax began building, "I'd probably cum right in math class, I just love staring at Mr. Logan's ass!!!"
