Monday, July 13th, 2009...
The thirteenth of July was my parents' anniversary, and both of them had asked off of work today. Fortunately for my sister and I, they were still going out of the house. I didn't know what their big plans were, only that those plans would keep them out of the house all day. They didn't leave until almost noon, apparently starting with going out to lunch, but it still felt like all day, as I waited for the opportunity to get fully dressed.
Once they finally left, I got dressed, but decided to take a different route than normal. I went into my mother's closet, and began looking through her clothes; I was already wearing my own chocolate-colored, satin ladies briefs, with an under-wire bra that matched in color. Overall, my mother was a bit of a classy woman, mostly owning skirt-suits, a few pant-suit outfits, pencil skirts, conservative blouses and such. But as I sifted through her things, I found a kinky side to her. Besides finding thongs and mesh bras, I found a few role-play outfits as well, including a cat suit and a playboy bunny outfit! While loyal to my sister, I had no problem letting my imagination have a good time with thoughts of my mother in those things, and it was getting me quite erect.
Finally, I began getting dressed. First, I stepped into a pair of tan pantyhose, followed by a black, full-body slip. It seemed a bit redundant to put on a full slip when I already wore a bra, but I mainly wore that bra for the cups to simulate breasts. Next I put on a white satin blouse, buttoning it up only halfway, to allow the slip to show, and tucked the bottom of it nicely into a black pencil skirt. Lastly, I threw on one of my mother's better suit jackets, leaving it open.
When I came downstairs to Mandy, she was sitting on the couch reading a book. She sat with her legs curled underneath her, and one elbow leaning on the arm of the couch. As for her attire, she wore a black leather mini skirt that obviously wrapped around rather than pulled up, and a white spaghetti strap tank top. Not much, but it turned me on nonetheless.
“Hey, sexy,” I said to Mandy, grabbing her attention.
“Hey!” she said with a smile, setting her book down and standing from the couch. She wrapped her arms over my shoulders and kissed me passionately, pressing her body to mine. I returned her kiss, firmly grabbing both cheeks of her ass and pulling her close, allowing her pussy to feel my erection. “Mm!” my sister moaned. “You know we're gonna fuck, why put so much on?”
“To make you work for it,” I replied playfully.
Mandy smiled, but suddenly took a step back. “Wait a minute, are those mom's
“Yeah,” I said sheepishly. “You wouldn't believe some of the things she has in her closet.”
“You naughty boy.” Mandy turned back to the couch, which was actually a pull-out bed, and unfolded it into it's bed shape. Before she could stand up, however, I grabbed her hips and pressed my cock against her ass as firmly as I could. Mandy stood up moaning, wrapping her hand back around my head as I began to kiss her neck and shoulder. Then I turned her around and pulled the spaghetti straps from her shoulders and lowered her top, exposing her breasts.
As I moved to suck her nipples, Mandy leaned away and lifted my chin. “Not yet,” she said with a sly smile.
I picked my sister up; she opened her legs to allow me a better hold. I whispered to her, “I'm in control today.”
I lay her down on the bed, quickly crawled over her, and consumed her nipple with my lips, lapping at it in an up and down motion. All Mandy could do was wrap her legs around me and moan loudly.
“Oh yes!” she cried out. “Use that tongue!”
I kissed my way back up her body until I found her mouth again, then grabbed her hand and put it to my cock. She rubbed well, over the skirt, and I knew my pre-cum was enough to soak through my mother's pantyhose and slip. I rolled to the side, putting Mandy on top of me and unsnapped her skirt, quickly tossing it aside. To no one's great surprise, she wore no panties underneath it, and she began grinding her pussy against my cock.
“Fuck me, little brother!” she begged.
I obliged her.
I rolled on top of her again, making sure I stayed between her legs. After allowing Mandy to unzip the rear of the pencil skirt I wore, I pulled it down and off, kicking it away. Rather than remove the full slip, I merely lifted the lower half, then lowered the front of the pantyhose and panties. I really didn't care how much of her juices were about to stain my mother's clothes. Finally, I once again pushed into my sister's pussy without a condom.
“Oh, God, Kyle!” Mandy screamed. “Oh, yes! Fuck me hard!”
I did as I was told, pumping her deep, pumping her hard. Then I rolled us again, putting my sister on top once more. “Ride me, bitch!” I commanded.
“Yes, Kyle! Yes!” Mandy replied, doing as I told her.
Suddenly I found myself holding her down, tight to my body, as I pushed up into her, unleashing my hot cum into her body. “Oh, fuck, yes!” my sister cried. After my last shot was fired, she simply fell onto me, catching her breath with my cock still inside her pussy.
Later that night, we were back on the pullout couch, both dressed for bed early. We were spooning while watching a movie, me wearing my icy blue baby doll night gown (and nothing underneath it), Mandy wearing her lavender purple one, also without panties. About halfway through our movie, we quit paying attention to it, as arousal started to get the better of us. I was already poking my sister's bare butt, my cock having lifted the front of my nightie and the back of hers as it grew erect. Mandy would occasionally push back into me, making me grow even more horny than I already was.
By now, my hand had found her breast and began caressing, as I moved my hips forward to press more into her. Before I knew it, Mandy had lifted her leg, and I was once again sliding into her. As one, we rolled up onto our knees, and I started fucking my sister doggie style. I slapped her ass cheeks a few times, making her yelp with ecstasy each time.
“You like that, Mandy?” I teased, hitting her ass again.
“Oh yes, Kyle,” she moaned. “I've been a bad, naughty girl. Spank me again. Uh!”
As I was getting close to cumming again, the worst thing imaginable happened. Our parents got home earlier than expected, and walked in through the front door while I still had my dick deep in my sister's pussy. Both of them froze, with looks of utter shock on their faces, unable to react to what they were seeing at first.
“Oh my god!” said Mandy, just as surprised to see them. I imagine that her face was turning as red as mine. However, as I was so close, I realized that I hadn't stopped pumping my sister.
“Mom, dad,” I softly pleaded, though I don't know for what. Was I begging them the opportunity to at least finish? Or was I begging them to show some leniency when they finally did something other than stare in total disbelief? I never did figure that out, but I never stopped fucking Mandy either. I finished rather quickly after that. The next thing that happened was my mother heading upstairs without a word, and my father approaching us with the angriest look I had ever seen in his eyes.
