Repaying the Favor

Tabby and I were walking home from the restaurant, takeout boxes in hand, and laughing as we went along. It was great spending some time with her, especially after everything that had been going on with us over the last few days. As we came to the house, I unlocked the door and opened it for Tabby, motioning her in first.

“Oh, quite the gentlewoman you are, sis,” she said as she walked inside. The lights were off inside like nobody was home. We both called out for Mom and Dad before I found a note on the kitchen counter:

“Had a small emergency. We'll be back late if not tomorrow morning. Call if you need us.”

“Well, looks like we're on our own for now,” I said as I put the note down. “So what should we do?”

We both stood there, thinking for a minute. The house all to ourselves, no parents, no anything. I was about to speak when-

“How about a scary movie? It's been a while since we saw one! We can protect each other during the bad parts!” Tabby said, putting the leftovers in the fridge. “How does that sound?”

Well, not exactly what I was going to suggest, but it still sounded fun. “OK, I'm going to change into my nightgown real quick. I'll get the popcorn while you get the movie. Just not the cabin one. That one's just too cheesy.”

After everything was all set and we were in our PJs, we both sat on the couch and turned the movie on. She ended up choosing this one about haunted mirrors. Kinda goofy, but it had a couple jump scares. At one particular point, a lady was taking a bath when the reflection in the water started attacking her. Tabby ended up jumping into my lap screaming, she was so scared. She turned to face me, laughing at her own reaction as I laughed as well. Our laughter calmed down, but we continued looking at each other, not even paying attention to the movie anymore.

“You, umm... You okay, Tabby?” I asked hesitantly, feeling her weight shift on my lap. I was trying not to get hard again, but with her plump ass lightly rubbing against me, it was a losing battle from the start. I felt my dick stiffening underneath her.

“Oh, yeah. I'm okay,” she replied. “I'm just... Well, I can feel you. You know, your... It's kind of...” Her face was growing red in the light of the TV, which neither of us was paying attention to any longer. I could feel the heat between her legs through the fabric of our pajamas, making me grow even harder until I was at full length. She started to lean a little closer to me. “I mean, your... It's making me...”

Whatever she was going to say next was completely lost as our lips touched, hesitantly at first. The kiss we shared was slow, lingering, yet every bit intense. I paused, pulling away briefly to look at my sister, her eyes fluttering open to stare at me again. In the small amount of light we had, I could plainly see something in her eyes. I had never seen it in anyone before, but I could tell what it was almost immediately: desire. My sister wanted me in ways sisters shouldn't want each other. That didn't bother me at all because, at that very moment, I felt the exact same about her.

I suddenly pulled her back to me and kissed her far more aggressively, my lust for her starting to overtake me. My fingers wove through her hair, pulling her closer to me as my tongue worked its way past her lips. Her own tongue began to dance around mine, passion fueling both of our actions. Her hands were on my back, clawing at my nightgown.

**** to feel and see more of her, I broke our kiss and began to frantically pull her shirt over her head. She lifted her arms up to help, her full breasts bouncing free as the fabric pulled away from them. Her hands then flew to the bottom of my nightgown, trying to do the same. I helped her in the same way, my naked body being exposed to her as it came over my head. She then hastily pulled her bottoms off, including her panties, to show me her nude figure. She was a magnificent sight: waxed pussy, toned abs, slender thighs, and her beautiful, heaving breasts. If there was such a thing as a perfect figure, I was positive at that moment she had it.

“Do you... do you like what you see?” she asked hesitantly, leaning back to give me a full view of her entire body. The light we had didn't do it justice, but it was still the most enticing thing I'd ever seen. My cock jumped at the sight of her, my excitement clearly evident. She gave a small giggle. “I'll take that as a yes.”

“And how about you? Am I- well, do you like me, too?” I asked hesitantly. I had always been supremely self-conscious given my special nature, but even with that aside, I still thought I wasn't the most glamorous girl. It was the typical thought process: I was too short, my chest was too big, my ass was too round, and my hair looked horrible. You know, typical teenage mindset. So, sitting there in the soft light, completely exposed to my darling sister, I felt on the verge of an anxiety attack.

She looked me over completely from head to toe, never pausing for long in one place. Her gaze stopped once she reached my eyes, and she gave me a warm, loving smile. She then leaned back toward me and kissed me gently, cradling my head in her hands. As she pulled back from the kiss, she looked me in the eyes again.

“You're absolutely beautiful, Bee. You're perfect.”

I had received compliments before, but this seemed like the most emotional one ever. I could feel my eyes welling up with tears, so I lunged back toward her, kissing her passionately, my hands roaming all over her back as hers held my head. She wrapped her legs around my waist, my cock pressing up against her belly. I could feel her chest pressing against me, her hard nipples prodding against my skin. I broke our kiss and immediately took one into my mouth, suckling it ravenously. Her moans of pleasure let me know I made the right move as she pulled my head into her voluptuous bosom.

“Oh god, Bee,” she whispered hoarsely. “Don't stop, please! Don't stop!”

I had no intention of it as I traced my tongue around her nipple, gently flicking it every now and again. Her fingers dug into my hair, my **** on her building her arousal with each passing second. I abandoned that breast and kissed my way across her chest to the other, wanting to give it equal attention. My hands had traveled down her back to her smooth ass, caressing it softly. I started to squeeze her butt firmly, pulling her hips towards mine, my dick now wedged between us. Her soft skin felt like heaven under my fingertips.

She was breathing rather heavily now as I continued my lashing of her breast with my tongue, coating her nipple with my saliva. As I parted from it, I gave a final kiss to it and looked up into Tabby's eyes, filled with lust. I wanted to make her feel incredible, just like she made me feel. It was the least I could do for her.

“Sit back on the couch,” I whispered to her. She didn't say a word as she slowly slid off my lap, my cock bouncing free from the captivity of our stomachs. She never took her eyes off of me as she sat down on the couch next to me. I slid off the couch and moved in front of her, parting her legs slowly. She didn't resist at all as her legs went wider, revealing her glistening pussy to me. The sight of her smooth lips covered in her juices made my temperature climb, my own pussy becoming drenched in response. I looked up at her as I moved slowly closer to her hot, pink entrance.

“Do you mind if I have a taste?” I asked.

She was breathing heavily, the look of anticipation in her eyes plainly visible. “Please, have all you want,” she sighed breathlessly.

That was all the encouragement I needed. I began by kissing the inside of her thighs, just shy of her warm pussy, my lips planting soft kisses all over. The scent of her sex was intoxicating. I moved closer, my lips touching her smooth skin. I heard her gasp, her body tensing as my lips touched her most private area. I slowly slid my tongue out past my lips and, hesitating for only a second before, slipped it past her delicate folds. Her juices tasted slightly salty on my buds, with just a hint of sweetness. She was, in a word, delectable.

As my tongue first connected with her lower reaches, Tabby took a sharp breath in. Her body tensed up as my tongue started to probe her lower reaches. Her hands held my head in place between her legs, giving me only enough space to move my tongue over her. I looked up at her and saw her eyes closed and mouth open, the pleasure of being eaten out etched on her face.

“Oh my- Oh, god, Bee!” she said in a hoarse whisper. I could tell she was enjoying this immensely and only wanted it to continue. Not wanting to disappoint her, I proceeded to lick her moist cunt heavily, savoring her juices as they dripped out of her. She released one hand from my head and brought it up to her breast, kneading it firmly. She would let out a high moan every now and then as my tongue would move along her slit. I didn't know why, but her sounds made my pussy become drenched and my cock harden like diamonds.

As I continued to explore her, my tongue moved up over her clit for the first time. This caused Tabby to yell out and jump slightly. At first, I thought I had hurt her. I pulled back, taking her hand from my head as I looked up at her.

“Tabby, I'm so sorry! I didn't mean to hurt you! I'll stop!”

Tabby, clearly seeing my distress, put a finger over my lips and shushed me calmly. As fearful as I must have looked to her, she looked completely at peace to me. She gazed at me with her sweet smile and brought me up to her, kissing me deeply.

“Don't apologize. You didn't hurt me at all. It was just really intense pleasure is all. Do you not know about that?”

To be honest, I only ever got myself off by jerking off my dick. Also, the health and biology courses I had in home school didn't really cover that much in terms of sex aside from the typical act, so I was rather clueless on some things. So, in the end, all I could do was shake my head slowly.

Tabby, the beautiful angel she is, giggled softly and lowered me back down between her legs. As I sat there, she used her hand to spread her pussy lips apart, exposing her pink center. Seeing it in full view made my heart jump. She used her other hand to hold mine and guide it to her wet snatch.

“This is the labia,” she said as she used my finger to touch her pussy lips. She moved my finger from there further in, making me touch her pink interior while guiding me to the small bud I had licked before. “And this is my clitoris or clit for short. It has a lot of nerve endings in it, so it's very sensitive.” As my finger touched it, she shivered slightly and let off a small moan, showing me just how sensitive it really was. “When you licked me there, it didn't hurt. It felt intensely good, like lightning shooting up my spine. Remember when I licked your pussy in the restaurant, and you started shaking and moaning?”

I thought back and remember that exact moment. It was the most enthralling, exciting feeling ever, and I craved it ever since. I nodded, signaling I did indeed know what she was referencing.

“Well, I was licking your clit at that point. So no, I wasn't in pain. I was in ecstasy. You made me feel that. Now,” she continued, “I'd really, really like you to do it again. Could you please?”

I could only sit there for a couple of seconds, my hand still against her pussy, and look at her. My mind was still wrapping itself around the concept of that kind of pleasure. Once it had sunk in, I didn't nod. I didn't speak. I only did one thing: smile at her. She smiled in return and leaned back against the couch again, releasing my hand and spreading her legs wider.

“Then come get me, my beautiful sister.”

That encouragement was all I needed. I buried my head between her legs, my tongue going directly to her clit. The sudden surprise made her yell out, her hands immediately pinning my head to her pussy. She held her breath and her body went completely rigid as I swirled my tongue all over her tiny bud, hoping to bring her as much pleasure as I could.

“Oh god, Bee! Fuck, that's it! Mmm! Yes, keep going!” she cried, her hips now rocking against my head. Her movement made it a little more difficult to focus on her pleasure button, but I made my best attempt. Her juices were flowing from her, covering my face as I ate her out. My tongue moved all over her pussy, making sure to leave no space untouched before returning to her clit.

By now, she was shaking constantly, giving off a soft whimper every couple of seconds. Both of her hands were squeezing her tits, kneading them intensely. Her eyes were tightly shut, the pleasure of my tongue overwhelming her. I grasped her hips, trying to steady her and stay firmly at her honey spot.

Suddenly, her shaking stopped as she started to tense up again. All of her muscles contracted. Her mouth was opened wide, but no sound was coming out. I kept going, licking her happily, as her legs squeezed my head.

“God, I'm cumming, Bee! I'm cumming! Oh, fuck!”

It was then that I knew I had done what I wanted as the rush of juices smothered my face. Her entire body shook, forcing my head out from between her legs. I sat back and watched as the throes of an intense orgasm rolled through her. Her hands grasped the couch cushions while she threw her head back, a high moan escaping her throat. I had never seen anyone cum before, much less that hard. Watching her do so was a sight to behold.

She came down from the high after several seconds, her body relaxing as she collapsed back on the couch. Every now and then, she would start to shake again as a powerful aftershock would roll through her, sending another bout of chills up her spine. Her breathing was heavy and labored. She looked at me, her lovely chest heaving with each breath, and smiled.

“That was a first for both of us, I think. You eating out a girl, and me being eaten out period. Not to mention, that was quite possibly the most intense orgasm I've had in my life. I couldn't do that on my own in a million years.”

She motioned for me to come up on the couch next to her, so I slid up next to her. She snuggled up next to me and placed her head on my arm, her hands falling to my lap. I could feel the occasional rumble pass through her, the evidence of my handiwork still affecting her.

“You are amazing, Bee. God, that was incredible.”

I felt pretty good about that entire experience. I was happy to have made my sister feel that good, and I was impressed that I actually got her to cum that hard on a first attempt. As good as it felt, though, I was still extremely hard from all the excitement and was craving release. Tabby must have sensed that, too, because what she said next took things to a whole new level between us.

“I want you inside me, Bee. Please, my sweet sister. Fuck me.”
