"Pleeeeaaaase" I let out a long sigh and unhooked her bra through her T-shirt.
"I unhooked it but you have to get it off" She struggled to get it out from under her, until she finally resolved to just take off her T-shirt and bra at once, and throw them on my floor along with her socks. She didn't seem to bothered about being almost naked, so I didn't let it bother me either, and before long, she was asleep again.
I laid awake for a while, stroking my sisters hair, and thinking about the exam I had to take next week. I was feeling guilty that I had all this time and didn't even bother to study. She must have been dreaming, because she kept mumbling and moving around. Then all of a sudden she started kissing my neck! I was a little shocked at first, but then I started to laugh and moved away from her. A few minutes later she started kissing my neck again, and moving her hand up and down my arm. I wondered what or whom she was dreaming about. She continued kissing my neck in her sleep. At first, it was just light sleepy kisses, but then they became longer and harder, but still sporadic. I really wasn't able to move any further away, and I had to admit it was feeling pretty good. Maybe it was the fact that I hadn't been with anyone for a while that was allowing me to give into it, but I figured it wasn't hurting anyone. She didn't even know what she was doing, so I just decided to run with it. Besides, it might be fun to mess with her a little bit too. I moved my hand to the back of her neck and lightly stroked her, encouraging her to continue. I closed my eyes to fake sleep in case she happened to wake up. I figured that neither one of us could be held accountable for anything if we are sleeping.
After a few minutes, I moved my self closer so her mouth was resting just below my ear. She somehow got the hint and began kissing and licking my earlobe. I let out a soft sigh, and cupped the back of her head in my hand a bit more forcefully to let her know I was responding. I began to get more excited, and I could feel the heat building between my legs. The idea that I was directing MY SISTER to unknowingly seduce me was getting me crazy. It made me feel so devious, and so out of my character. After a few minutes, she was steadily nibbling and kissing my ear, and driving me wild. The more I encouraged her, the more she reacted. Her hand was moving steadily across my arm, and she started to occasionally push herself lightly into my hip. I knew if I let her continue she would eventually wake up. I wanted to see how excited she could get while she slept. I rolled myself on my side slightly toward her, and pushed her head back down to my neck in one motion, placing my left hand just above her hip. She adjusted to the change and nestled herself back into me, eventually resuming her kisses on my neckline, just above my shirt collar. While my right hand was still on the back of her head, I slid my left hand across her hips and legs, and back up, stopping now and then to trace the line of her panties with my finger over her but and back. She responded with an assuring groan. When her hips started to move again, I let my hand fall between her legs, and rest on her inner thighs, pressing slightly against her crotch. I let it rest there for a moment and I could feel her warmth on the back of my hand, and noticed that her panties were slightly damp. I had never touched another girl before, and I was growing curios to see what it was like. I turned my hand around and softly cupped her crotch in my palm. I could feel the outline of her pussy in my hand. She moved her leg further up my hip, giving my hand more room. I started to very lightly stroke the front of her panties up and down the covered folds of her vagina, slightly increasing the pressure a little more each time, but not too much. As I stroked the soft fabric over her pussy, I could feel her warmth, and mine, beginning to grow. I concentrated my fingers on the small area of her clit, sliding down occasionally over her opening. By now, she was squeezing my arm, and her kisses were a lot more coherent. The intensity between us began to increase, and I could feel her breath on my neck. She let out soft assuring moans in her sleep, letting me know I was doing well. After a few minutes of teasing her with my hand, I was dizzy with lust. Our bodies were beginning to sweat and we both began to move more rhythmically with each other. I increased the pressure of my rubbing until her panties were gliding across her slick skin. Her hips were moving freely, and she started moaning louder. Her kisses turned into long gentle bites on my neck, and I knew she was not far from cumming. The closer I thought she got the harder and faster I went. I was lost in concentration, fueled by my own increasing desire to make my sister cum. I needed her to cum, and it almost felt as though I would too. Suddenly she pulled away from me, and I stopped immediately.
I laid frozen, still keeping my eyes closed, but knowing full well that there was no way I could have pretended to be asleep at this point. I felt her move quickly, and pull herself away from me almost completely. My hands fell away from her and for the next second or two I was sure she was scrambling to get as far away from me as she could. I felt the bed bouncing and I thought she was getting up. I wondered if I should just lie here and pretend to be asleep or try and make up some excuse of why I was trying to molest my own sister. Suddenly I felt her body crash into mine again. "Please don't stop" she whispered to me as she grabbed my hand and guided it with her own over her now naked pussy. Before I could say anything she wrapped her mouth over my ear and moaned softly, assuring me, she wanted this as much as I did. I needed no further encouragement as I let my hand take control and explore my sister's pussy. She inhaled deeply as my fingers passed over her clit and found her opening. I let two of my fingers slip inside of her, and she pulled her hand off mine and brought it back up to her clit. The feel of her pussy was amazing. So soft and wet and hot. I remember thinking that I understood now why men are so eager to fuck, and how fucking awesome a woman's wet pussy must feel around their stiff cocks.
I could feel the walls of her cunt squeezing around my fingers as I thrust them in and out of her. Every time I pumped into my sister, she would moan into my ear, sending electric shocks through my whole body. She thrust her hips in the air and met every thrust of my hand with her pelvis. I quickly grabbed on to one of her tits with my mouth and began to suck and nibble on it as hard as I could. I felt her whole body stiffen beneath me, and her cunt grab a hold of my fingers. I could feel her juices began to soak my hand and I thought I was going to explode right there. She buried her face into my neck to let me know she was cumming. I didn't stop what I was doing until she was finished. My pussy ached to be touched. I shoved my hand down the front of my shorts and let my fingers seek out my throbbing clit. I wanted to cum along with my sister. Before I knew what was happening, my shorts were around my ankles, and her fingers penetrating me. I rolled flat on my back and spread my legs as wide as I could. My sister crawled on top of me and put her lips on mine. We kissed as she fingered me to a violent orgasm.
We remained still, with my sister's fingers buried inside of me. I wanted to speak, but I didn't know what to say. I felt as though we had done something that would change our lives forever, and I didn't care. I could never look at her the same way again. She hovered above me, looking straight into my eyes, slowly pumping her fingers in and out of me. I stumbled for something to say, but she cut me off. "That was better than I ever imagined. I hope you're not mad."
"Why would I be mad?"
"You don't think I was sleeping do you? I've wanted to do that with you for so long."
"What do you mean? You were awake the whole time?" She smiled at me, withdrawing her hand from me and putting them in her mouth.
"Fuck. How come you never said anything?"
She took her fingers out of her mouth and sat up. "What was I supposed to say?"
"Well how long have you wanted to?"
"I don't know…a while I guess, but I didn't know if you would. I figured I'd see what you would do if I came on to you in my sleep. It didn't take long."
"No I guess it didn't."
She giggled and kissed me straight on the mouth. Our tongues met and swirled around each other's. Damn my sister was a good kisser. She broke our kiss and trailed down my neck. She removed my shirt without a fight, and sucked on my nipples until they were rock hard and my pussy was tingling again. She dragged her tongue across my stomach and stopped just above my slit. "I'm gonna fuck you so good you'll forget I'm your sister." She continued to run her tongue down my thighs and down my legs. She kissed and licked my toes and back up my legs. She kissed and licked everywhere but my pussy. I wanted to feel her tongue in me. My pussy ached to be touched. I reached my hand down to play with my clit, but she grabbed my hand and placed it between her own legs. "Not yet" she said.
I started to roll her clit between my fingers. She leaned over me again and we kissed as she rode my hand. Suddenly she lowered mouth back down and put her tongue in my ass. I never felt anything so hot in my life. She pinched and teased my clit while fucking my ass with her tongue, and I came harder than I ever have in my life. Obviously, this wasn't my sister's first time with another girl. I found out later that her and her best friend have been "experimenting" for some time now. I never really thought seriously about being with another woman, especially my own sister, but now I was eager to please her, and would do anything I could to do so.
