Chapter One

 

So, I've always been a bit of a tomboy. Not in all ways, I mean, I liked to look hot and sexy, but not in a slutty way. I mean, not with showing a lot of cleavage, say, or wearing a miniskirt. In fact, I mostly didn't like dresses. But I did have, I don't know, like an ego trip knowing that the boys wanted me so much.

Of course it also made me kind of squirmy and uncomfortable being looked at like that, and having some idea of what they wanted to do to me. But I didn't mind it. I wasn't going to play into it too much. I kept my hair fairly simple, about shoulder length, sometimes a little shorter. At the same time, I kept it nice and thick and soft, with bangs cutting across my forehead.

I was not, in other words, trying to pretend I was a boy. And while I didn't wear tops that would show cleavage I wore them tight enough for people to know I was definitely not a guy. I didn't want to wear high heels, but I did have a thing for boots.

And while I didn't want to wear frilly, lacy stuff on the outside, I was partial to wearing them as lingerie on the inside where nobody could see. I loved lacy, sexy lingerie, including thongs and G-strings.

Now one of the things I had done when I was younger, not even into my teens, was to climb trees a lot. One of the ones which seemed easy was the tree next to the back porch, because then I could climb right up onto the roof over the porch and then get into my room without anyone noticing.

That was just a game when I was younger, but as I became older it became a very practical solution to what I regarded as too much parental supervision. And even after I turned 18 and my parents granted me more freedom, I kept in practice using that route from time to time.

As it happened, I was home a bit earlier than expected due to a date which had gone wrong. God was he boring! I didn't want to admit this to anyone, so decided to sneak in the back way. I was quite practiced at climbing this tree and supporting myself on the railing of the porch and the roof. I got up there without any problem.

And that's when I found the problem, well, not so much a problem, but a shock.

You see, it was a wide porch with a wide roof, and my window was at the far end. At this end, just as I climbed onto the roof and sat up, was the window to my sister's room. As it happened, the curtains were open, and the lights were on, but my sister, Olivia, wasn't there.

I vaguely recalled now that she was having a sleepover with some friends. And there was blonde Taylor and cool Beth on her bed, both naked. Taylor was actually on her knees, her face pressed against the pillow and her bottom raised high while Beth was fucking her from behind with a strap-on dildo!

I could see that the same ropes that tied Taylor's wrists and arms together behind her back, wrapped around her chest and squeezed her full breasts firmly. Meanwhile, Beth, who was smaller, had short, black hair, and high, small breasts, was yanking on her hair, and roughly groping her breast as she rammed the big dildo into her with hard, powerful thrusts.

I'm not sure which of us was more astonished. I saw her maybe a second or two before Beth turned and saw me. I yelped and jerked away from the window, almost falling off the roof before scrambling back down the tree and taking off.

I went to my friend Michelle's place to pass some time, not eager to return and face them, or my sister, who they would probably tell. And of course, what the hell they were doing that for in my sister's room with my sister home. Obviously, my sister knew about it. Did that mean she like, took part in stuff like that? The idea was bizarre. Because she had always struck me as so straightlaced.

I also have to say that the sight of those two naked and having kinky sex had taken my breath away at the time, and did so again every time the memory flashed into my head. I'm not sure why, unless perhaps it was just that I had never considered that particular type of sex. I mean, it wasn't that lesbian sex or straight girls playing around with lesbian sex was a shock to me. I just had never imagined it in the context of being tied up and having a girl fuck you as if she was a guy.

Whenever I thought about girls and play sex, I thought about kissing and stroking and caressing and sliding bodies together. Which, to be honest, I was awfully, awfully curious to try. I was just way too careful of my reputation to do it with just anyone.

But anyway, I had thought of it more as a gentle, loving, tender, sort of sex without the wild, frantic thrusting and grunting that you see from guys. Not that I would know personally, but I'd seen a lot of videos.

Yes, I was still a virgin. And it wasn't that I didn't have the curiosity, but just like with girls, I was careful of my reputation and hadn't found anyone to trust yet.

Anyway, I came back after a couple of hours and decided to let myself in normally. I slipped up the stairs, and into my room, closing the door quickly and quietly. I sighed in relief and peeled off my T-shirt, then slipped my pants down and off after toeing off my shoes. I slipped off my bra and then went over to the bed to tug the sheets aside.

That was when Beth turned on the light, and I saw her sitting back on my bed watching me.

I let out a little cry of shock and she pressed her finger to her lips as I clapped my arms across my chest.

"You and I have to talk," she said.

"I-I don't know what you mean, I gulped, red-faced.

She was wearing a red nightshirt which came down to mid-thigh and was tight enough to show she had no bra underneath. Her dark, spiky hair dropped down around her chin as she motioned me forward with her finger.

"I will give you the benefit of a doubt that what you saw was accidental," she said.

I started to protest that of course I hadn't had a clue what I was going to encounter and she shushed me.

"Fine," she said. "But I would rather you not tell Olivia or your mother about it."

I stared at her in surprise. "How can Olivia not know?" I asked.

She smirked at me. "Your sister is not the most aware person in the world when it comes to sexuality," she said. "She had to drive your mother somewhere, and left us alone in the house for an hour. We passed the time the way I felt like passing the time."

I stared at her in surprise. "Wait a minute, you brought ropes and a strap-on dildo to a sleepover and my sister didn't know a thing? Give me a break."

"I know it's a little edgy, but me and Taylor were going to do it in the bathroom, without her knowing a thing. That was part of the excitement. Doing it so near other people without them finding out. We like taking chances, doing edgy stuff like that. It's kind of like public sex but without anyone noticing. At least if you do it right."

She slid forward off the bed, and in doing so the hem of the nightshirt slid up so high I could see her pussy briefly. She stood up before me, and I backed up. She grinned and came closer until I felt the wall against my bare buttocks.

"Don't you have fantasies, Megan? Maybe some dark, nasty fantasies that you don't share with anyone? Maybe some kinky thoughts about doing things that you don't ever dare do? Taking chances, taking risks?

"N-N-No!" I squeaked, intimidated despite her being only an inch taller than me.

"Are you suuuuure?" she drawled.

She looked down at my arms crossed over my chest and smiled.

"You have a very sexy body to not be doing anything fun with it," she said.

"I do lots of fun stuff!" I gulped. "I don't have to be a sex maniac like you guys!"

"When not sex maniacs. We're just enjoying being girls."

She let her fingers caress my upper arm as she said that and smiled at me. "Maybe you should try some time, little girl."

I scowled at her, for I was always 'little girl', or 'baby girl', or 'little sister' to her and the rest of Olivia's friends.

"You don't know what I might've done!" I exclaimed.

"You're an open book to me, little shy girl," she said.

"Just because I don't show my breasts off to anyone who happens to be in my room -!"

I gasp as she suddenly reached out and gripped my wrists, then lifted them up and back and pressed hard against the wall above my head.

"Hey!" I hissed. "Let's go!"

She grinned at me and looked down. "I can see your boobies, Megan," she taunted me.

My face had already been red but now it flushed hotly as she looked down at my bare breasts. I tried to twist away but it was fairly clear she was stronger than me. She had always been a very fit girl, heavily into sports.

Maybe like a lesbian?!

"You definitely have nice tits," she said. "Nice and big and round but not too big so that they sag. Now they're great tits. You should show them off more."

"Some of us have morals!" I hissed.

In truth, my chest was tight and my heart was beating a mile a minute. And it wasn't for fear of her, nor even embarrassment. This was Beth, tough girl Beth, who I now knew liked to have sex with girls. And here I was practically naked in front of her and she pinned me to the wall! It didn't take a pervert to imagine what might now happen.

What was tumbling and churning uncontrollably through my mind was the indecision about what I wanted to happen. I'd always been afraid of approaching a girl in case she said no and then told others. But if Beth approached me and tried to have sex with me, then it was on her. Besides, even though she was only a couple of years older, she didn't really hang with anybody I knew.

So I didn't know if I wanted her to actually start anything or not. A part of me definitely did, filled with a wild sense of anticipation and excitement. Another part of me was desperately afraid of giving myself away and being the subject of rumors for the rest of my life.

"Your nipples certainly are hard," she said as she looked down at the small, sharply peaked pink buttons.

"It's the air conditioning!" I gulped.

She shifted my wrists together and then pinned them with her left hand as she leaned forward, then dropped her right hand and squeezed my left breast gently. She caught the nipple between the pads of her thumb and forefinger and rolled them in opposite directions.

A powerful rush of sensation spread through my breast and then into my chest and straight up into my mind. She plucked at it then stroked it again. A moment later her hand slid down my taut, trembling body, her fingers caressing my abdomen.

"Nice and firm body you have here, little sister," she purred.

Her fingers slipped lower, dipping down into the front of my panties, then stroking lower and lower until they found my naked sex. I jerked sharply, instinctively, letting out a helpless gasp of shock as a tremendous burst of sensation hit me along with a dark, psychic jolt.

"What a nice, soft, tight little pussy you have, little girl."

Her fingers rubbed against the top of my sex, right over my clitoris, and I jerked against her hold on my wrists again, though not, to be honest, as hard as I could have. I was shaking and gasping as a tremendous rush of need and hunger spread through my body and swept over my mind.

"D-Don't!" I gasped, my voice almost a whisper.

"Why not, little girl?" she whispered as she let her finger slowly sink in between the lips of my sex. "You feel warm and wet."

She leaned in and let her tongue ease up along my neck and in under my earlobe which she sucked lightly.

"Are you afraid someone will think you're a... lesbian" she whispered.

"I-I'm not!" I gasped.

The heat was churning wildly within me, I was rapidly losing control of my body as I felt my buttocks grinding against the wall behind me. I had never felt this level of excitement before, to the point my entire body felt as if it was quivering.

Her hand pushed deeper into the small crotch of my panties, forcing the strings lower on my hips so that they barely stayed up. I felt her finger sliding between the lips of my sex and pushing up inside me as her thumb stroked rapidly across my clitoris.

"Oh! Oh, please!" I gasped helplessly.

"Please what, little girl?" she whispered. "Please fuck you? Was that what you were going to ask? Were you going to beg me to fuck you?"

"No!" I gasped.

"Wouldn't you like to be my little bitch?" she cooed in a low voice.

And then to my shame, the climax tore through me. Nor was there any way I could hide it, as my buttocks began to slap frantically against the wall while my hips ground furiously against her fingers. I gurgled and gasped, swallowing the cries of pleasure I wanted to issue, rolling my head back against the wall as her fingers sent waves of pleasure through my trembling body.

"What a responsive little bitch you are," she said. "Hot, sexy little slut," she taunted. "But I didn't give you permission to come on my fingers, slut!"

She kept stroking me anyway, and didn't stop until I sagged against the wall, gulping in air dazedly.

"What a bad little girl you are," she said.

She roughly spun me around and pressed me against the wall then yanked my panties down to my ankles and pulled them off. She gripped my wrist and drew them back behind my back even as my mind started to recover from the incredible shockwave of heat and pleasure and passion which the orgasm had sent flooding through it.

"W-Wait! Oh, wait!" I gasped. "What are you doing!?"

What she was doing was tying my wrists together behind my back! But by the time I realized that she had already done it. She roughly yanked me back by the hair so that I stumbled back and fell sprawling across my bed.

She climbed into bed with me, gripping my thighs and forcing them wide then dropping low and staring at my naked sex for long seconds.

"You have a gorgeous little cunt, you gorgeous little cunt she said with a small giggle.

Then she started to lick, her tongue swirling around and around my clitoris as her thumb spread me open.

I lay there on my back, gasping, jerking my head up to stare at her then dropping it back, overwhelmed by all that was happening, and the violent, churning emotions and passions and sensation sweeping through me. Her fingers slid into my tight pussy, pressing upwards against the front wall of my sex as she licked down strong and fast.

My body began to burn again, and I writhed and twisted on the bed below her, gulping in air, my chest heaving as I whimpered and moaned in passion and excitement. Another orgasm tore through me, so intense that I arched my back to the point I was afraid I might break my spine. Not that I cared. I cared only for wallowing in that incredible wave of passion and heat and intense pleasure that swept over me for long, long, long seconds.

I got lightheaded because I didn't even dare breathe, until finally I was forced to suck in a deep, frantic breath and then barely stop from screaming it out again as the climax continued to set my muscles to spasming and my nerve endings to burning.

"What a responsive little slut you are, baby sister," Beth said.

She let her tongue zigzagged up across my trembling abdomen and belly, and then slid upwards until she was sucking and licking and chewing at my breasts each in turn. I could do nothing but lay on my bound arms, whimpering and gasping at each new flood of sensation, at each new rush of excitement and heat.

By the time she abandoned my breasts they were throbbing wildly. She climbed up and then straddled my head, sinking her pussy down against my mouth as she peeled her nightshirt up and off. She reached down and gathered in my hair, then jammed my mouth against her sex.

"I just showed you what to do, little girl. Let's hope you've learned something or else I'm going to turn you on your belly and spank your little round ass."

Oh my God!

I was looking face-to-face with her naked sex even as she peeled her lips open and pressed it against my mouth. Her other hand tugged on my hair and I winced in pain.

"Get to work, little slut," she growled.

I started licking, hesitant, at first, then with growing enthusiasm and excitement for how wild and thrilling and exciting and new and to my naïve mind, sophisticated and adult this was. And so I licked determinedly, taking every instruction she gave without protest despite them being accompanied by stinging little tugs on my hair.

I made her come, with her grinding her sopping pussy back and forth over my mouth and face to leave me gasping. She slid off and chewed, licked, and sucked her way back down my body until she was working on my pussy once again. It didn't take long for me to start writhing and twisting and helplessly panting in pleasure once more.

Then she rose up onto her knees, straddling my left thigh as she gripped my right and half rolled me onto my side. She worked her naked sex in against mine as she lifted my right leg high along her chest, then reached forward with her right hand, wrapped my hair around it, and jerked it sharply back to force my back to bow.

Her left hand soon found one of my breasts, squeezing roughly as she ground herself against me.

I felt in a haze, in a daze, gasping and whimpering, my mind churning and swirling in confusion and heat, passion burning wildly away as floods of sensation spread out through my body.

"You're a sexy little slut, Megan," she whispered.
