Francis waltzed into my room where I was lying on my bed reading a Cussler novel. “Hey, what the hell is a lap dance?”

I was focused on the book so I asked “A what?”

“A lap dance. Mel asked me last night to give him a lap dance but I don’t know what he was talking about so I said no way. What is it?”

My mind started running, first off I was going to have to body slam Mel for asking my 18 year old sister to do something like that, second, my sister was still naïve enough not to know, third, why was she asking me?

“Why you asking me? Maybe I don’t know either.”

“Well if you don’t then I’ll go ask somebody else, maybe dad.”

I smiled an evil grin, “I don’t think that’s a question for dad.”

“Then you do know, tell me.”

I’d never had a girl do a lap dance for me but I’d seen videos on the net and some at parties so I knew that there were different versions, mostly because of what the woman was or was not wearing when she did it. “I don’t think that’s something you should be doing at your age. Maybe when you are old enough to drink you’ll be old enough to do something like that.”

“Then it’s dirty, nasty?”

“I don’t know about dirty and nasty but it is sexual, kind of like foreplay to real screwing.”

Fran fidgeted a little “Did a girl ever do one for you?” she asked cautiously.

“No, but I saw some at some parties I’ve been too, they can get pretty hot.”

“Okay” said my sister as she sat on the end of my bed, “tell me. What’s so special? What do the boy and girl do?”

“First of all the boy doesn’t do anything except get hot. The girl does the work, the dance which is supposed to turn the guy on. She does a booty shake, some hip swinging and twisting; throwing her ass in his face then sits on his lap and does the same thing while sitting on his legs. He gets turned on then they go somewhere and fuck.”

“Do they always have sex after?”

“No, I’ve seen girls do that for several guys then ignore them completely later. Some girls like to show their junk, it’s another type of cock teasing.” Fran looked at me for a few moments; I could see thoughts swirling around her head.

“Thanks, I don’t think I could do something like that.” She got off the bed and left.

I picked up my book again but couldn’t concentrate on Dirk and Al, Fran had reset my brain to sex mode and I was thinking about some lap dances I’d seen.

My sister and I ignored each other for a couple of weeks more. I was a little curious what she was doing with Mel but I didn’t bring it up. He was in her class at school so he was pretty much a non-person in my group of friends. Besides, as long as she didn’t get knocked up, I didn’t really care too much about what she was doing when the lights were out.

I came home from basketball practice early one night, our parents were still working. When I went past my sister’s room I heard music booming through the partially open door. I pushed it wider to tell her to put something on I wanted to hear but my words jammed tight in my throat. Fran had her back to me so she didn’t see me standing in the door as she jimmied and shimmied her ass, keeping a booty rocking, hip rolling beat with the music. She was wearing only bra and panties as she practiced her dance. Her butt was swinging circles in the air, her legs pumping it up and down at the same time. I’d never seen a girl’s ass move in so many different directions at once. It was fascinating, and a little sexy.

No – it was a lot sexy.

I pushed the door wider, leaned on the jamb and watched my sister. She put on more show then slowly stepped around. She looked up and saw me standing in her room and froze in place for two heartbeats then began to shriek. The terror in her eyes faded quickly, turning to rage when she recognized me. “YOU FUCKING ASSHOLE WHAT IN THE HELL ARE YOU DOING HERE!?”

I was grinning like an idiot, “Watching you dance, what do you think?”

Fran grabbed her bathrobe off the floor and threw it over her shoulders. She slammed the off button on her music box and took up her verbal assault on me again “You bastard, you scared the shit out of me. What do you think you were doing?”

“Hey the goddamn door was open bitch, don’t get all fucked up at me, I heard the music and stopped to see what you were doing. What are you doing, practicing a lap dance like you asked me about?”

My sister was calming down. We weren’t strangers to each other in our underwear so that didn’t embarrass her but she started to turn red “I found some dance videos on the web so I was trying to do what they were doing.”

“Lap dance videos?”

She burned redder “Yeah, it’s kind of fun making my butt swing around like that, it’s a good workout too.”

“Well from the short show I just got it looked to me like you learned some pretty sensational moves. You were rocking girl.”

Fran brightened “You think so? I haven’t done anything like that for Mel yet so I don’t know.”

“Tell you what Sis; let me sit in that chair and you put the music back on. Dance for me and I’ll be your critic.

She hesitated, looking at me strangely, “You want me to do that with you watching me?”

“Well ya, that’s what it’s all about. The girls show their stuff for the men; the men get hot.”

“You mean that if I do this you’re gonna get hot or are you gonna get hot for me?”

“What fucking difference does it make?”

“Well don’t think you get to stick your dick in me just because I dance for you, OK?”

“Okay, that wasn’t my plan anyway, put the music on, let’s see what you got.”

Fran threw her robe onto the bed and walked over to the boom box. She fiddled with the disk until she got the tune she wanted then stepped back in front of me. The desk chair I was sitting in had arms so she leaned over and put her hands on the chair and her face just inches from mine. I looked down her front at her tits which were swinging prettily inside her thin bra. The music started thumping a heavy beat and she began to whip her hips back and forth, swiveling at the waist. Her head was rigid, not moving, her eyes locked on my face while her body began to pulse and gyrate even more.

I tore my eyes away from her bouncing body and looked into hers. She smiled at me then flicked the end of her tongue over her lips then formed an ‘O’ with her mouth and blew a gentle puff of breath at me. My nuts pulled up and my cock started to swell. She pushed up from the chair and turned away from me and started giving me a show of her ass as it whipped from side to side, bouncing her butt cheeks while she stepped in place to the drum beat.

As she danced she flailed the air with her hair, tossing her head so that the long blonde locks flew in circles about her head. She reached behind her, put her hands on her back then slid them down and over her ass as she bent at the waist giving me an awesome view of her butt and legs. She moved her feet wider apart which opened the junction of her legs, I could see the outline of her body crack under then thin tight material of lacy blue panties. She put the palms of her hands on the inside of her thighs and twitched her butt even more; I was staring at her pussy which she was boldly highlighting for me.

Fran shook her body at me for a couple of minutes, twisting, turning, stretching, and caressing herself then finally gave up. She turned the music off then turned to me, breathing heavily, she glowed from the heat of the exertion. “What do you think, was it okay?”

My cock was grossly inflated, my own temperature was up around boiling, “You looked good, Sis, I’m not sure I’ve ever seen a girl with that many moves before.”

She smiled prettily, happily, “Did I turn you on, did it work for you?”

What the hell, she wanted to know so I stood up, the bulge of my erection announcing to her eyes just what she and done to me. Fran studied the distended form of my cock then looked me in the eyes “Awesome! That looks like a pussy pleaser from here, I did that?”

It was time to change the subject “Are you going to practice some more?”

“Not today, I’m wore out but come back tomorrow, can you?”

Fucking right I could come back. What I had seen was a treat for my eyes and erotic as hell, it didn’t matter that it was my sister waving her ass at me. Yeah, I’d be back so I asked her “When?”

“I think we will be alone after dinner, mom and dad are going bowling with Bob and Margie.”

“Okay, it’s a date, you want me to bring a couple of friends for a variety of opinions on your style and moves?”

She turned shocked eyes on me “What?”

I walked past her, my nuts were beginning to ache, “I was kidding, it will only be me.” I could feel her eyes on my back when I left.

If I told you I wasn’t anticipating my private lap dance I’d go to Hell for lying. I gave up a night with my friends to see Fran flipping her butt in my face. I watched my sister as she scuttled around the house and kept seeing her in only panties and bra, shaking like she was electrified. She caught me staring at her a couple of times and gave me a quick private smile but no hint of what she was thinking.

That night after our parents left Fran came into the living room, “Come back in about five minutes, I’ll be ready.”

I lost all concentration on the TV as I pictured my sister’s moves in my mind, my dick was already reacting. I went to my own room and changed into looser fitting pants, my Dockers were too tight, and I knew I would need room to grow.

She was standing beside a cushioned dining room chair in a short white skirt and brief tank top. I could tell by the peaks in the material of the shirt she wasn’t wearing a bra. The hem of the white skirt was only a couple of inches below her crotch which left a lot of long shapely thighs and legs bared for viewing. The length of her legs was accented by white pumps on 2” heels. Her cheeks and neck were tinted embarrassment red, her eyes wary. I sensed she was faltering, “Hey look Fran, if you don’t want to do this, its okay, I can go hang with Danny.”

That did it, my generous offer to let her off the hook was all it took to make up her mind “Sit down.” She set her CD in place and found the right music while I sat.

She started by standing straight, facing me, arms stretched over her head, holding her long hair off her head. The music thumped and she bumped. My sister arched and bowed her body to the beat, eyes closed, as if she were alone. She dropped her hair, put her hands on her waist and began tossing her long locks while rotating her hips and butt, belly dancing moves. Her feet were moving her slowly in a circle as she moved to the music. She wasn’t doing a ‘lap dance’ but what she was doing was just as sexy. She lifted her hands off her hips and began rubbing them up and down her body, first her sides then stomach. As she massaged her skin under the top it lifted far enough I could see the swell of her tits, I got a hint of the brown puckered skin at the tip of them. I was reacting to her, I could feel my pulse quicken, my cock swelling.

She danced until the song was done then stopped. She was breathing deeply which caused her tits to rise and fall. “What do you think, is that a good warm up?”

“If that was the warm up, then what comes next is going to hurt my nuts for sure.”

Fran gave me a wickedly feminine smile “Then let’s see if I can ruin you sex life.” She punched the play button on the sound box and the next act began.

She turned her back to me and bent double at the waist, her head almost to the floor. She put her hands around her ankles then began to vibrate her butt. It was bouncing too fast to be shaking, her vibrating globes caused the short skirt to sway violently as it pulled up giving me a full view of her scantily covered ass. Fran worked it for a little bit while I stared, fascinated by what my sister could do, the control she had. She slowly raised herself upright then spread her feet wide apart as her hips began to roll and pulse. She turned to me and moved forward until she was just inches from me. I looked up, under the short top where her breasts were quivering, her nipples jutting from the circles of dark skin. I moved my eyes from the distraction of her tits to her eyes, she was smiling mischievously, impishly as she looked at me. My prick was filling with hot racing blood.

Fran put her hands on my shoulders and held herself in place while her body gyrated to the thumping song, her breasts were inches from my face, the skirt whipping across her thighs, my cock continued to fill. She moved her hands then spun away from me again then straddled my legs, the inside of her thighs were rubbing the outside of mine, her red panties dancing before my eyes. Fran bent at the waist again which put her butt just inches from me. I detected the scent of her body mixed with the fragrance of cologne. I was damn glad I’d changed into loose fitting pants. I wished for a fist full of dollars so I could stuff then into her underwear as she danced.

I knew the song was coming to an end, so did Fran. She bent her knees slightly and started bouncing her butt on the bulge in my lap. She put her hands on my knees then twitched and rubbed my swelling pants with her cheeks. I was two seconds from overload when the music stopped. I wanted to grab my sister by the waist and jam her down on me until my balls spilled but I sat there immobile and let her get away.

She move across the room and leaned on her bureau, panting with exertion, face flushed. “Goddamn that’s a lot of fucking work. I need something cold to drink. Come on.”

We found some iced tea in the fridge and after our tumblers were full Fran asked me with anticipation, “Whaja think?”

“Hot. Awesome. Awesomely hot! The only thing that could make it hotter is if you wore a thong, not full panties. Where in hell did you learn to move like that?”

She beamed her pleasure at my warm critique. “I’ve been practicing, its kinda fun trying to do moves like those.”

“So, what’s fun about it? You worked up a sweat and did all the work, I just sat there and enjoyed the show.”

“You got turned on didn’t you?” She looked at my groin, my erection had dwindled to about half sized but it was still evidence of her effect.

“Well, yeah, but what’s in it for the girl?” I was curious and Fran was willing to share her thoughts.

“I’m not sure but I think it’s the power. Yeah, the power. I like the feeling when boys react to me because of my sex. It’s a power trip and I’m working on new ways of showing it, of turning guys on because it turns me on to do it.”

“So you are learning how to be a cock tease, well it worked for me, I got a steel rod in my pants watching you, how about you?”

My sister blushed a lovely shade, “Kind of.” she admitted.

I wasn’t done “What about the butt bounce at the end when you rubbed your ass on my hard-on. Was that for me, you, or the grand finale to the show?”

She didn’t answer my question, she stood straight, put her glass down and asked “Can I practice some more?”

That was a question she didn’t have to ask.

The first thing she did when we got back to her room was to open the second drawer of her bureau and pull out a skimpy white thong. She didn’t try to hide or tell me to look away when she took her panties off then pulled the miniscule thong up her legs. I didn’t get a look under her skirt but my cock turned to rock again.

She posed herself to start by standing behind me, not only her hands resting on my shoulder, but her head as well. Long blonde hair cascaded down and over my chest, I could smell apple blossoms in it; her warm breath breezing across my ear. My cock yowled with pain it stretched so hard.

The music started slowly and Fran lifted her head then began caressing my chest and torso with her hands. I could feel her body begin to swing, her tits pressed against the back of my neck. She watched the lump in my lap grow from big to huge. My erection convulsed and spit a gob of lube into my shorts.

She swayed around the chair until she was facing me again, her hands caressing my neck as she came around. She bent down so far I thought she was going to kiss me but she just puckered her lips and smiled, showing me a set of white even teeth. She put the tip of her tongue on her upper lip and flicked it at me, taunting me. Her eyes were sparkling blue, sunlight reflecting off a lake.

She rested her hands on my knees for support, I could see her tits clearly down the front of her top, she didn’t seem to mind me staring at them, actually I’m sure she was showing them for me. Her hips were rocking and humping to the musical rhythm, her head perfectly still. My balls were starting to cry.

She stood straight and began to turn, twisting and bending sensually, eyes closed as the music moved her. Her hands started roaming, touching herself, flowing down the curves of her breasts, stomach, down her thighs then back up. They ended up cupping her own tits, holding them up while thumbs teased circles around the nipples.

She came back to reality slowly, looking at me, recognizing I was still in the chair. She stepped to me and sat on my legs facing me and hooked her arms around my neck. Eyes closed my sister started swinging and swaying on my lap, I could feel the heat of her body blistering my cock. At first she gyrated, moving her hips in circles, but the sway changed subtly to a back and forth motion as if she were fucking me. She rested her forehead next to my head and rocked her ass, rubbing her crotch on my overgrown member. Her breath was scalding my neck. Fran’s movement got stronger and I couldn’t stop myself. I reached under her skirt held her hips as she chafed my erection. Fran didn’t slow down, the music was reaching a climax and so was she. Just as the final explosion of music boomed from the box my sister started to vibrate then she gasped loudly in my ear. She lost all rhythm as she quivered on my lap. I was stunned that she had reached an orgasm.

The room was quiet except for her heavy breathing. Fran sat limply on me for a few moments then sat up. She was glowing red from the exercise, or embarrassment, I wasn’t sure. She stared at me, unknown emotions drifting in her eyes when she stood. She looked at the bulge in my lap then started to undo my pants. She twisted open the button, used both hands to pull the zipper down then urged me silently to lift my ass while she striped my clothes down my legs. My erection rejoiced in the open air and stood proudly, waving at my sister. “Look at what I did to you.” she murmured with awe.

I was struck dumb by her actions so I only nodded and gripped my hard-on, squeezing it lightly so another blob of pre-cum oozed from the end. Fran stepped back to the CD player and started another track. She leaned forward again which gave me another view of her tits then put her hands on her knees and pulled them up the insides of her thighs. As she straightened up again the skirt rose up letting me watch as her fingers caressed the front of the thong then she lifted her hands to massage her breasts and started to move with the music.

She danced spiritedly but seductively, giving me a full show of her butt and pussy as she bumped and swayed. I was tugging on my solid cock, slowly jacking off while my sister shimmied her ass in time to the quickened beat of the music. Gradually she moved closer then stepped across my legs; just before she eased her weight onto my thighs she pulled the thong aside, baring the slick swollen lips of her pussy then bent her knees until the end of my cock slipped into the hot tender center between her legs, she locked her arms around my neck, locked her eyes on mine and continued the lap dance.
