Tegan:

Staring down at Sara's body, I couldn't help the rush of blood that went straight to my already throbbing clit. "Fuck" I whispered. I bent over her beautiful form and felt her arms wrap around my neck as I lowered my hips against hers. I could feel her trembling beneath me, but the look on her face begged me not to stop. "Sara, are you sure?" I asked praying that she would say yes. Instead, I felt her hand trail down my back and grab the bottom of my shirt pulling it up over my head. I guess that's a yes.

I began kissing her shoulder, letting my teeth graze her soft skin as I worked my way back to her neck. I heard her gasp and moan a little and knew I couldn't hold back much longer, but when she rocked her hips causing the perfect amount of friction between our bodies, that was it.

I pushed myself up off her body and ran my hands down her sides grabbing her hips and pinning them to the mattress. I smiled as her beautiful eyes, so much like my own, yet so very different, widened with anticipation. Did she have any idea what she was getting herself into? Could I really do the things I have done to other women, to Sara? These thoughts flashed in my mind but as soon as my fingers found, and began teasing, her soaked pussy, they were answered with a whimpering "oh god, Tegan" which I decided was definitely a yes.

Sara:

The anticipation was killing me, driving me completely out of my fucking mind. I'd spent too long wanting this, wanting her, to back down now so when she asked me if I was sure all I could do was show her. So I reached down and pulled her tshirt off. If that didn't sink in, I was going to have to just flip her over and start it myself. Thankfully, my beautiful and talented, (and sometimes annoying), sister was also very smart. Soon I felt her mouth on me again and I couldn't keep quiet. She knew exactly where to kiss, how to tease with her teeth, to work me into a shaking frenzy. My body was reacting to her and I had no control what-so-ever. My hips rolled up into hers and that seemed to ignite her once more.

I felt Tegan's hands steadily pulling their way down my sides before latching onto my narrow hips and roughly stilling them against the bed. I wanted to beg, I did, but that stubborn streak kept my mouth shut even when I knew that my face would give me away. When I saw that smirk cross her lips, I knew I was right. I had gotten so lost in her eyes that I didn't feel her fingertips slip across my skin as they made their way to my dripping cunt. The spark I felt when they reached their destination though, was unmistakable. This time I could not bury my voice as I gasped out her name.

I bent my knee up to her hip, as I felt her slip just the tips of two of her slender fingers into me, pulling them out to trace their way up to my aching clit. I whimpered loudly as she began circling it slowly still staring at my face. She hadn't dropped her eyes from mine once. Tegan was taking her dear sweet time, almost like she was studying my reactions, memorizing everything. I watched as she blinked slowly and sucked her bottom lip in between her teeth and I felt her fingers at my entrance again. I had no time to think before I felt that delicious pressure of her, slipping into me, ripping a moan from my chest.

Tegan:

"Mmmm Tegan" Sara moaned as I finally gave her what we'd both been waiting for. I steadily pushed two fingers deep into her body, feeling her wrap tightly around me. My god, I couldn't believe how amazing she felt and the sound of my name coming from her lips drove me mad. I needed to feel more, hear more of her cries. I began a slow rhythm pushing deep and pulling out almost completely. The whole time I couldn't tear my eyes away from her beautiful face. "God, Tegan, yes" she whimpered as I felt her hand slipping up my stomach toward my still partially covered chest.

As she palmed my breast, it's my turn to moan. My heart was pounding in my chest, and I could feel hers beating wildly as I continued to press deeper into her slick core. I knew this shouldn't be happening, she's my sister for fuck's sake, but I had wanted her for so long I couldn't stop.

"More Tee, please" she begged. Oh holy fucking Christ, I felt my underwear dampen even further as I heard her words, "Don't hold back", (gasp), "not gonna break". She wanted more? I can do that, I thought as I pulled my fingers back, then, adding a third, I thrust even deeper inside of her without hesitation.

She arched violently up into me, the loudest cry coming from deep inside her. "OH FUCK, Tegan, don't stop. Pleeease" she begged. Her arms wrapped around my back, fingers digging into my skin, pulling me closer to her body as I began to pump in and out of her harder. If this was what she wanted, it was what I would give her.

Sara:

I felt everything begin to build, threatening to boil over. My eyes slammed shut, my whole body rebelling against me. I could feel Tegan begin to curl her agile fingers deep inside of me and I knew I was going to cum soon. My lungs began to burn as I realized I had forgotten to breathe momentarily. "Teg...Tegan, I'm gonna" I stuttered trying to tell her what was happening but before I could get it out I felt her slow her pace, remove her fingers from my clenching walls and heard her voice.

"Not yet." she growled. I nearly lost my cool. I couldn't believe this was happening. She knew exactly what she was putting my body through and yet, she just stared at me, hungry, and un-moving as I shook. I felt like I had that day so many years ago, back in Calgary when I borrowed her favorite belt that she never wore. She saw it around my hips, and instantly began demanding that I take it off.

"Fuck you, Tegan" I yelled at her. "You never wear it anyway and mine's gone missing!" I could see that I was pissing her off but I didn't care. In fact somewhere in my subconscious, I wanted to see how far I could push her before she did something about it.

"Take. Off. MY. Belt. Sara" she growled, venomously through clenched teeth.

"No. I'm. Wearing. It. Tegan" I growled back, purposely mocking my older, tougher sister. I didn't see her come at me until she spun me around pushing me into the wall. I felt her forearm press across by back, just below my shoulder blades as her other hand reached around slipping down my stomach and began to un-buckle the leather.

That was all it took to add total and shocking lust to my anger. When she finally let me go, I spun to face her, wanting to pin her to the opposite wall and shove my hand right into her boxers, but I couldn't move. So I just stared at her, panting before she turned and walked out the door.

That mix of pure Lust and a hint of anger was exactly how I felt as I looked up at her, kneeling between my thighs, staring back at me with a triumphant smirk on her face.
