The weekend after my eighteenth birthday turned out to be the most eventful two days of my young life. My parents were out of town - dad had a conference the following Monday; he'd taken Mom for a mini vacation Saturday and Sunday, then the conference, and they'd be home Tuesday. My sister Jodi was spending the weekend with a girlfriend.
So Friday afternoon I found myself all alone in our two story McMansion. I watched some TV, nothing good on yet, made myself a sandwich. Though about calling up some buddies and going out - I'd been strictly warned not to have anyone over while mom and dad were away.
So, bored, I wandered from room to room. I went into my parents room, bed neatly made up, closet organized. My parents were a little anal about the neatness thing.
I wandered down the hall, peeked into Jodi's room. It was the opposite of mom and dad's obsessive neatness. The bed wasn't made; in fact I couldn't immediately even see the top sheet. Clothes were scattered all over the place, I couldn't even SEE the floor. Man, that girl was a pig!
Thinking of Jodi I began to get a boner. She was only a year older but already seemed way ahead of me socially. She'd been dating for a couple of years already and never seemed to lack a date with popular senior football players at our local college.
In spite of her disorganized room Jodi was about the prettiest girl I'd ever laid eyes on. Five two, 110 pounds, nice boobs, not too big, not too small. Honey blonde hair that fell around her shoulders like liquid gold. Big soft brown eyes.
Now I had a full on raging woodie. I was a little ashamed thinking such thoughts about my sister, imagining myself kissing and sucking her beautiful boobs, feeling her surround my cock as I pumped her slowly and lovingly...
In the middle of her bed was a pair of pink panties, all wadded up. I picked them up, they were soft and smooth, faintly stained near the bottom of the front. Brought them to my face, inhaled her heady sweet smell.
My dick was throbbing now. I wondered how Jodi felt wearing those panties. Without thinking much about what I was doing I slipped out of my jeans, shirt, and underwear and stepped into her panties, slowly pulling them up. They cradled my throbbing election, all but about two inches which stuck out past the waistband.
I almost came on the spot! Regaining some control I laid down on her bed, my eyes half closed, lost in a new world of pleasure.
Something was under my back. I grabbed the offending object, a lacy white bra. I wondered what Jodi and other girls felt wearing one of those. I put my arms around the straps, tried to hook it behind my back...it was too difficult. I finally put it on backwards, hooked it in front, then spun it and put my arms in. I've since seen my wife do that but at eighteen almost no experience with girls and no idea how to work a bra.
The bra was a little tight but it had some sort of elastic so it worked on my larger chest. The cups sort of hung...I wondered what it would be like to have boobs like a girl. I looked around, found several more panties, stuffed them into the cups. The effect was really weird, strange.
Lying back on my sister's bed I started to rub my engorged cock. It was slick with precum, I knew I was about to blow a giant load...thinking about Jodi, the smooth feeling of her lingerie on my body...
Suddenly I saw a flash, heard a whir and a giggle. My eyes popped open and standing in the door was my sister, cell phone in hand. She'd just taken my picture! My heart let into my throat!
"What the fuck are you doing home?" I screamed as I leapt out of bed and grabbed for her.
Jodi pulled back. "Uh, un, little brother, hands off! I push this button and that pic goes right to Facebook, everyone in town will see it! Now calm down!"
"Jeez sis, please don't do that!"
"Ok, sit back on the bed," she commanded, "Let's talk."
Realizing I had no choice I sat on her bed, heart pounding. I had no idea how I'd get out of this. I couldn't imagine the humiliation if everyone saw that picture of me wearing my sister's panties and bra!
"Now relax, bro, " Jodi said. "That picture stays private for now and I won't show it to anyone, as long as you do what I tell you. Do you understand?"
Relieved I nodded. "Now, first rule, no crap from you, understand? I tell you to do something, you do it, no questions asked. You got that?"
Another nod, "Yes, I understand, no crap. Just please, please, don't show anyone that picture!"
"Now now, don't worry, your secrets safe with me," she said in a reassuring tone. "Now lie back down, get all comfy, I want to take some more pictures of you." She silenced my protest with a wave of her hand. I stretched out on her bed.
"What were you doing when I came in? Rubbing your little weenie I think? " I started to tell her it wasn't that little, I'd measured it, it was a bit over eight inches when it was hard. Being a eighteen year old boy it was hard a lot, and amazingly in spite of the recent shock of being discovered it was still hard.
"Bad boy, we'll have to punish you! Lay back on the bed!"
I lay back slowly. Still unsure where she was taking this but very very curious. This was a side of Jodi I'd never seen.
Jodi jumped off the bed and hopped over to her dresser. She started opening drawers; apparently unable to find what she wanted she mumbled, "Shit". Then looked around at the clothes strewn all over her room, bend down and plucked up a crumpled pair of panty hose. Stepped a few feet, retrieved another pair.
Hopping back on the bed she grabbed my wrists, pulled them together. "Now just relax little bro..." she said as she wrapped the pantyhose around my wrists, knotted them. Then she moved up, pulled my hands up and looped and knotted the pantyhose around the bed frame. My arms were now tied over my head.
Hopping to the foot of the bed she repeated this with my ankles. I was secured to the bed.
Jodi stood next to the bed, admiring her handiwork. Glancing down she gazed at my still raging boner. "My, my, you certainly seem to be enjoying yourself!" she declared.
I couldn't say much, my throat was suddenly very dry.
"You look so nice I think I'll dress to match! We can be sisters, I always wanted a sister!" With that she jumped around the bed deftly avoiding piles of clothing lying all over the floor. Searching through the mess she found a white babydoll nightgown. She turned her back to me, slipped her shirt over her head, her pants and shoes off...unhooked her bra. Slipped the diaphanous negligee over her arms and head and let it fall naturally down her body.
Jodi turned toward me. "How do I look, sister?" I could clearly see her beautiful boobs, areola brown and round, nipples hard and protruding. I could see her chest move with every breath she took. She was the most beautiful thing my eyes had ever beheld.
And one look at my hardon, now pulsing as my heart beat, answered her question. But I added almost as an afterthought, "Jodi, you are...beautiful."
She smiled at me. "Now for your punishment!" She jumped on the bed next to me, began tickling me. "Oh, Jodi, no, please, stop it! Dammit stop!"
She didn't stop for a while though, until I was in tears. Finally she squatted on my shoulders, her legs on either side of me. "Remember when we used to wrestle and I'd hold you down like this?" Truthfully I'd been able to pin her since I was five but whatever she wanted to remember I wasn't going to disagree.
Laughing, the crotch of her panties was an inch from my mouth. That's when a strange -- or maybe not so strange -- thing happened. I don't know why but suddenly I took a deep breath and moved my head up, cupping my mouth on the crotch of her satin panties. I opened my mouth and exhale, making the cloth very warm from my breath.
Jodi's hips jerked instinctively, driving her satin clad pussy into my mouth. "Uhhh!" she grunted in surprise. "Whaaa...?
But I wasn't waiting or explaining. I took another breath, did it again, exhale, hot breath. I smelled her female odor mixed with the satin smell of her panties, it was the most incredibly intoxicating scent I'd ever inhaled! She grunted again as her hips drove into my waiting mouth harder this time.
On and on, and soon neither of us was questioning or talking, she just kept grinding into my face harder and harder and faster. I don't know how long it lasted, not long enough, maybe five minutes, and I felt her go stiff and let out a long moan, "UUUUHHHHH...OOOOHHHHHH..." and she humped against me five, six times hard then went stiff, shaking violently for a few seconds.
When she pulled back she was panting. I saw a wet spot where my mouth had been, she'd wet her panties from the inside. It was the first female orgasm I'd ever seen and I think her first too.
Panting, Jodi untied my wrists then lifted her leg, prepared to roll off me. I grabbed her hips and forced her back down. I didn't want her to get up, not ever! I wanted to breathe in her intoxicating female scent, feel her warm crotch against my face.
Soon her hips began to move again as she ground herself into me. I have no idea where I got the idea but suddenly my hand moved behind her, between her panties and her ass. I moved my hand back and down, pulling the smooth fabric away from her crotch.
I took in the beautiful site of her vagina, all pink, red, shiny, coated with her female juices. She began to lower herself; instinctively I stuck my tongue up and out, penetrating the glistening lips of her beautiful pussy.
Jodi moaned louder then, "Ohhhhh...God...!" and lowered herself fully down, impaling herself on my tongue. Her juices tasted and smelled wonderful! I began to lick and she began to move her hips back and forth, sliding down so my tongue raked across the hard little button at the top of her vag.
I didn't know what a clit was but I knew this was driving Jodi wild! She began to moan louder and louder and her hips began an uncontrollable dance across my tongue. It was a little painful but I barely noticed! All I wanted to do, my entire world, consisted of my beautiful sister and her magic twat!
Jodi gave a final hard hump and screamed. I felt a rush of fluid as she ejaculated into her panties and my greedy mouth. I licked and licked, lapping up every glorious drop!
Her climax went on for a long time (I've learned that women have much longer orgasms than men do). Finally she rolled off me and collapsed onto the bed, covered with sweat.
She lay beside me, her head on my chest, panting for a while. Finally she could breathe normally. "Damn, that was...was..."
