Don't try this at home. Being in the trunk of a car can lead to asphyxiation from noxious fumes. And being in the trunk of a car and/or being tied up, giving head, and/or being naked in a car is also bad. Think if you were in a wreck.
You do what I want...
"I just wanted you to know that I'm completely serious," my hot blonde sister said. Both of us were kneeling on her bed. She'd just gotten completely naked. First, she'd pulled off the tight white t-shirt she was wearing, showing her black lace bra. Then she'd reached behind her back and undid it, pulling it off to reveal what the 34C garment had been covering, a pair of pale moons with red, rock hard nipples. Then she'd pulled off her jeans and panties, sliding them off while staring at my face, a smirk on hers. And here she was now, kneeling, knees open, her dirty blonde bush slowly fluffing after being restrained by the panties, her clit hood and labia just barely visible. The blonde with the pale skin was wearing blue eyeshadow and red lipstick, her blonde hair done so it was a beauty halo. Mary had firm, visible abs and a narrow waist widening nicely to muscular hips and thighs. She was a college cheerleader, a junior, and I had just turned eighteen.
"So, what happens next?" I said. Since she was obviously showing off to me, I didn't bother hiding the boner in my jeans, a size too large for my spare frame. I couldn't help but be self-conscious as my t-shirt hung down off my narrow shoulders. Unlike my sister, I had lightly tan skin and jet black hair, kind of just sticking out everywhere.
"You do whatever I want," she said, smiling, "and next Saturday I'll do whatever you want." Her eyes blazed. "Anything."
"Like, when you say I do whatever you want, can you give me some rough parameters?"
Mary giggled. "I'll give you very rough parameters. In fact, 'rough' is the name of the game tonight."
I stared at my naked sister as she started to breathe heavy and her skin started to flush. "So, like, um..."
Mary's face fell. "Do I have to spell it out for you? You're going to treat me
very roughly
."
"Like, is it a game or...?"
"You'll see," she finally said huffily. "If I tell you more, I'm afraid it won't be spontaneous. Now get out. I'm going to get dressed."
"What should I wear?" I asked.
"That's perfect," which made me even more confused when she came out of her room wearing a gold sequin dress, strapless, so her broad chest and cleavage were visible. Around her neck she had a thin leather collar with a charm. The dress went down to about two inches past her butt and she was wearing matching heels. "Okay, let's go," she said.
"Should I be dressed better?" I asked.
"Nope. Like I said, you're dressed perfectly."
Mary drove us to the mall and parked in a shady spot, actually a pitch black spot, given that it was after dinner time. Getting out, she had a gold sequin purse that matched her dress and a little shopping bag. Strolling confidently, we went into the outer door of one of those swanky restaurants that malls have and down the side corridor to the bathrooms. Whispering so we weren't overheard, Mary pulled some duct tape out of the bag, just enough to show it to me, then gave her first set of instructions. "Okay, I'm livestreaming to your phone. You have to watch and video me peeing." I guess I flinched or looked repulsed or something because she suddenly became almost whiny, "You said you'd do whatever I told you."
Well, I hadn't but she hadn't really given me a choice so here I was. "Okay, watch and video you peeing," I repeated back, all business.
My sister smiled again. "Yeah, then you follow me out to the car. I'll open the trunk, you push me in and use the tape," she gestured, "to tape my mouth shut and my wrists together behind my back. Then you drive to the location I just sent you. There's a low concrete building there for storage. It's not used; the metal door's unlocked." Mary worked for the parks. "While I'm in the trunk, tear my dress off me, then drag me in there by my hair - don't worry if I get skinned knees or anything - and then take the tape off my mouth so I can tell you what to do next." I stared at my sister after she just told me to assault her and kidnap her. "Got that?" she asked, her brow furrowing again as if she thought I would back out.
Right. Business like, "Trunk, tape, drive, tear off dress and drag you by your hair like a caveman."
Her smile returned. "Perfect!" she said and kissed me on the cheek before shoving the shopping bag into my arms and going into the ladies' room. I probably should have gone into the men's room but I didn't think of that, just squeezed myself into the corner at the end of the restroom corridor and watched my sister on my phone.
It was black, the sound of heels clacking on a tile floor, then the sound of a stall door shutting. After the multicolored whirligig of her taking the phone out, Mary attached it to the door of the stall. She was bent over looking at the camera, her mouth set as she got it perfect. Standing back up, Mary pulled her dress up to her hips, showing gold cotton panties, pulled those down to just below her knees, showing her full dirty blonde bush. Then she sat on the toilet and...peed. I could hear the hiss and continuous splash as she let go and I could watch the stream of almost clear fluid shooting out behind Mary's clitoral hood like a stream from a coffee maker. She just stared expressionlessly at the camera. I didn't know what I was supposed to get from this but I was videoing and I found myself, to my surprise, being turned on at this intrusion - wanted by her or not - into such a private act.
Finished, Mary used some tissue to wipe herself then, looking to make certain nobody was in the stalls on either side, pulled her panties down and her feet out of them, both at once. Bunching up the cotton, she shoved it into her mouth, closed her mouth, then pointed at her mouth. She winked at the camera, then grabbed it and dropped it into her purse. I heard the sound of her washing her hands - later I would wonder why she bothered - and then she was out. Not looking at me, purse on her arm, strolling confidently in her heels, Mary left the building, me stalking after her.
My sister was pointedly ignoring me, which was good, because I didn't want to sneak lest somebody think I was an unwanted attacker. At our car, a gold sedan, she opened the trunk and seemed to be rummaging inside. I realized the light in the trunk wasn't on as I came up behind the leggy blonde and pushed her in. Mary squirmed and pretended to fight, murmuring with her mouth closed and panties inside as I pulled off a strip of tape to put over her lips, then more tape to bind her wrists behind her back. The so-called struggles - more wriggling actually - had the hem of her dress all the way up to her waist, her pussy clearly visible. Also, one perfectly round tit had escaped from her dress, her nipple rock hard. "Mmm. Mmm." she grunted as I closed the trunk, looked around to make certain there weren't any problems, and got in the car and left.
The spot Mary sent was an out of the way park, generally unused, just some green space surrounded by trees with the concrete building near the asphalt parking lot. A metal cable blocked the gravel driveway but I just went around that on a path that was obviously well traveled. A distant streetlight and a full moon provided the only illumination in the cool air as I opened the trunk to find Mary waiting. She immediately started struggling as I tried to get her dress off her. Hand on her chest, I tried just tearing it off, grabbing the neck and then the hem, both to no luck. Finally I manhandled Mary onto her stomach, all while she was wriggling and squirming, pulled the zipper down to open it, and tore it off. In the struggle she lost both shoes and she was left wearing only a strapless black bra. I undid that, freeing both of her well shaped breasts, and left it in the trunk with her dress.
"This is what you wanted," I said as I grabbed a fistful of blonde hair and started trying to haul my sister out of the trunk. She actually helped, her legs opening wide so she could get one out and then the other, bent over because of my hand but still on her feet. I got a really good view of her wet swollen pussy. As I closed the trunk Mary dropped to her knees. I dragged the naked girl across the asphalt parking lot and down the concrete walkway. Going relatively slow to keep the damage to a minimum, she still ended up with both knees and the tops of both feet skinned up and bleeding. She didn't cry, though, or really try to stand, just scooted along on her knees while my grip on her hair kept her from falling onto her face.
The metal door was indeed unlocked and, as I pulled it open, it made a low 'whoof' sound. Then I was dragging my naked sister by her hair inside the cold storage room. Frosted windows provided an eerie light, enough to clearly see Mary and her goosebumps and rock hard nipples as she knelt on the cold floor. Thinking she wouldn't want me to be, I wasn't gentle as I ripped the duct tape off the blonde's mouth. She disgorged her panties and, panting, said, "Perfect," then shivered as she smiled up at me. "Can I have some water?" she said and nodded where there were some 'provisions:' wine, water, nuts. I opened a bottle and tilted it into her mouth like a baby. "Okay, next," she said, once she'd had enough, "I want you to slap me around."
"Slap where?" I asked, looking at her well-made face, lipstick mostly gone from the tape, her perky tits, her muscular round ass.
"My face," she said and I gave her cheek a little slap. "No, like, really slap it." I slapped harder. "No, you fucking weakling," she almost shouted, "slap my face as hard as you can!" Smack! reverberated through the room. Her head flew sideways and she fell onto the floor. It was hard to tell from the light but I think her cheek was immediately starting to color. "That's perfect," Mary said as she tried to get up and ended up sitting bare cheeked on the cold floor, one foot drawn up to the other stretched thigh. "But hold my hair so I don't fall over and you can keep slapping. Oh, and be sure to do both sides."
