I need to start by making one fact abundantly clear—I’m as straight as they come. If you have any doubts, you can just ask my husband. Nothing makes me happier than feeling his big, hard shaft impale me as he grabs my tits. It’s one of the greatest things on earth. Of course, having gotten that out of the way, I’ll admit that straight or not, I can appreciate a truly excellent kiss, even if it comes from another girl. Even if that girl is my younger sister.

A couple of weeks ago, my Baxter and I agreed to let my nineteen-year-old sister Tori move in with us. She’d been living at home, but things got pretty tense with Mom and Dad after she came out and announced she was a lesbian. Nothing against my parents; they’re just pretty traditional in their views, so it led to some harsh conversations. Baxter and I had an unused room in our house, and after she came to us with her plea, we felt like we couldn’t say no.

I have to tell you, it has been truly wonderful having my sister around. Baxter’s a firefighter, and his schedule has him living at the firehouse every weekend. During those first couple weekends with Baxter out of the house, Tori and I really had some wonderful opportunities to reconnect. It had been seven years since we both lived under the same roof, so we both loved the late nights talking about life, love, and everything over a glass of wine.

With as close as our new arrangement was bringing us, I guess it made sense that when Tori came up to me today with her unusual request, I didn’t immediately shoot it down.

“Hey Trish, can I talk to you about something?” She asked about an hour after Baxter left to start his latest weekend shift. I was about to joke about how obvious that answer should be, but the serious look in her eyes made me realize that whatever it was, it must be a big deal.

“Absolutely,” I replied, matching her tone. “What’s up?”

“Okay, just hear me out on this,” she began, toying with one of the pretty opal earrings that she’d been wearing nonstop since she asked us about moving in. “So there’s this girl that I’m really into. We’re super close, and I want to make a move on her, but I need to do it right, and I was thinking you could help me.”

I let out a soft chuckle. “Tori, you know as well as I do that I’m as straight as straight gets. I’m probably going to be a terrible giver of advice on how to pick up women.”

“No, no, that’s just it,” she replied. “This girl I’m interested in is super straight, too. That’s what makes this perfect. If I could get input from a girl who’s completely straight, like you, it would help me know if I’m on the right track with her.” Tori gave her earring another little rub. “Please, would you help me?”

“Okay, fine, you win,” I laughed, rolling my eyes. “So, what’s your plan to seduce this totally straight woman you’re so smitten with?”

“Well,” she said, pausing for a moment to look me over, “I think if I asked her, she’d let me give her a kiss. What I was thinking was that maybe I could kiss you, and you could tell me if you liked it or not. Could I kiss you, Trish?”

I had to admit, a little part of me was floored by her request. I mean, this is my sister I’m talking about, just coming out and asking to kiss me. Family members don’t kiss. At least not in the way that I think Tori is suggesting. If that in itself wasn’t enough, there was still the fact that I am completely straight, with no serious interest in kissing another girl. My knee-jerk reaction was to say absolutely not and to shut her down.

Before I could shoot down her request, though, I found myself looking at Tori as she stood there, toying with her earring. It wasn’t like she was that far out of line. Here she was, smitten over some woman, and all she wants to know is whether she can give a satisfying kiss or not. Who was I to stand in the way of that? Besides, it’s just one kiss. It’s not like it would hurt anything. Letting out a little sigh, I nodded my head.

“Sure, I guess,” I smiled. “But you know I’m only doing this because you’re my kid sister.”

Tori couldn’t have grinned any more brightly if she wanted to as she clapped her hands. “Yes, of course!” She said. “I know you’ll absolutely love it!”

“Okay,” I chuckled, taking a step closer to her. “Show me what you’ve got.”

I closed my eyes, tilted my head, and puckered up. As I stood there, waiting, I could hear Tori taking a deep breath. The next moment, I felt the warmth of her body as she pressed gently into mine. Her arms gently wrapped around my waist, and I could feel breath on my lips. I may be straight, but I had to admit that this was pretty nice so far.

What came next nearly knocked me off my feet.

As soon as her lips met mine, it was a sensation unlike anything I’d ever felt before. It was like I’d been living in a black-and-white world, and suddenly a vivid splash of color came in and took over. From the instant her warm, soft, feminine lips met mine, I knew this was going to be the best kiss I’d ever received. Better than the kiss on my wedding day. Better than the kiss I shared with Baxter the first time we made love. Better than anything and everything.

Before I knew what I was doing, my mouth began to open, and I felt Tori’s tongue tentatively make its way to mine. My God, her delicate, feminine tongue was so divine. The way our tongues began dancing and exploring one another was in stark contrast to Baxter’s sometimes clumsy approach. This was elegant. This was graceful. This was beautiful.

Somehow, as the seconds ticked on, the kiss just got better and better. As we stood there, making out in earnest, I just couldn’t believe how incredible my sister was at kissing. Everything about the experience was turning me on. I loved the feel of her soft cheeks against mine, another contrast to Baxter’s eternal stubble. Her perfume was so sensual, too. There wasn’t a thing about the way she kissed that I didn’t absolutely love. She gently nibbled one of my lips, and I found myself moaning into her mouth as I felt myself becoming wet between my legs. I let out a small whimper.

After what could have just as easily been a minute or a day, our lips somehow managed to break free. I opened my eyes, staring into my sister's as she smiled tenderly.

“So,” she whispered, “was it good?”

“Girl,” I panted, “that was… just, wow.”

Tori’s smile brightened. “So can we keep doing this then? You know, for practice?”

Tori didn’t need any practice. For that, I was certain. Still, there was no way I was going to say no to the opportunity to get more of her earth-shattering kisses. I grinned, pressing my lips back into hers as my response.

The whole weekend went by in a whirlwind. It felt like I barely got anything done around the house with how busy I was making out with Tori. We wrapped our arms around each other every chance we got, our lips pressed together in bliss. And every single time was absolutely incredible.

By the time Baxter got home, I nearly dragged him to the bedroom with a weekend of pent-up horniness I needed to take care of. He was barely in the bed before I had his pants down and my lips wrapped around his cock, sucking him off so he’d be nice and hard when he fucked me. After going down on me, he mounted me, and I finally got a weekend full of arousal out.

As wonderful as the sex with Baxter was, there was one tiny problem. Every time he went in to kiss me, it felt almost bleak in comparison to what I’d been getting from my sister. I still kissed him back, of course, but it just didn’t compare. It was so rough and clumsy compared to the way my sister kissed. More than once, I tried imagining Tori kissing me when Baxter went in for a kiss. It helped a lot, but it still wasn’t as good as the real thing.

After that night, I found myself making excuses to avoid kissing Baxter. I also found myself making excuses to be alone with Tori whenever I could, so we could continue practicing her kissing skills. Don’t get me wrong—I’m definitely straight, but I just couldn’t help but love the way that girl kissed me, and I wanted it every chance I got.

The next weekend, almost as soon as Baxter’s car pulled out of the driveway, I was on top of Tori, pressing my lips to hers and moaning into her mouth. After a couple of minutes, Tori gave me a gentle push back, breaking off the kiss so she could speak.

“Hey Trish,” she began. “Can we talk? There’s something I’ve been meaning to ask you.”

“Of course,” I smiled as I climbed off her and took a seat in the chair across from her. “What’s up?”

“Okay, first of all, thank you. I was able to make out with this girl I like, and she really loved it. I feel like you helped me a ton, so thank you for that.”

“No problem,” I said, a hint of worry entering my voice. “Does this mean you don’t want to practice kissing anymore?” Inside, I was trembling. I could hardly imagine life without Tori’s kisses. She was seriously the best kisser I’d ever known.

“Oh, no, nothing like that. I think the more we practice, the better.” I'm sure she could sense my relief at her response. “No, I wanted to talk to you about something else. See, as well as that part went, I kinda want to take things to the next level with this girl, and I was hoping you’d be able to help me out again.”

I gave my sister a quizzical look. “Help you out? Like how? I don’t know what else we could do beyond kissing practice. You know I’m straight as anything, Tor.”

“Exactly,” she replied, toying with her earring. “So if we try something and you like it, I know she will, too. I swear, it’s not that different from kissing, but you’ll love it way more. What do you say? Can you help me one more time?”

I thought about her request. Could I really love whatever she was thinking of more than kissing? Her kisses are out of this world. My curiosity piqued, I found my head nodding in response.

“Okay, if you swear I’ll like it that much, I’m willing to hear you out. What’s this next step you’re wanting to take?”

“It’s nothing too wild. We’re already kissing, so it’s just a logical next step, really. What I want is to start out kissing and then, while that’s going on, I want to keep going, kissing and touching you… everywhere. See? It’s just barely the next level of kissing. You’ve got to be okay with that. Could we try it, please?”

My eyes went wide as I stared at my sister. Kissing and touching me everywhere? Even… down there? At first I didn’t even know what to say in response. I’m as straight as a girl can get. I’d never once considered letting another girl go down on me. Especially not my sister. I stared into Tori’s eyes as she sat there, playing with her earrings and watching my expression.

After what felt like an eternity staring at each other, I let out a sigh in resignation and nodded my head. After all, this was just helping my sister take the next step with some girl she was interested in. It wasn’t like she really wanted to do this to me. It was just for practice. Besides, as wound up as Tori got me last weekend, it might be nice to get off this weekend.

Tori giggled and thanked me, and before I knew it, we were making out again in earnest. I had to admit, knowing what was coming only helped build my anticipation. By the time Tori started helping me out of my shirt and bra, my pussy was drenched. By the time my pants were hitting the floor, my panties were soaked through.

And then the kisses started. Oh my God, I cannot begin to tell you what it felt like. If Tori kissing me on the lips was a whole new world of color and beauty, feeling her lips and hands on my body as she started working her way down my naked form was another plane of existence. When her lips found my left nipple, I cried out in ecstasy. I nearly orgasmed right then and there when her delicate fingers gave my right breast a soft squeeze. It was ambrosia. I only wanted more.

Tori gently guided me onto the sofa, pulling my hips to the edge of the seat as she kneeled before me, kissing up and down my thighs. Her hands came up and started working my breasts as she did. I tried to stifle my moans, but it was so difficult. Baxter loved going down on me, and more than once we did it right here on this same sofa. But the way Tori was doing this, the way she was building me up, it was out of this world.

Finally, I felt her breath on my mound, followed by a long, hot, slow lick straight up my slit. My body shuddered, and I threw my head back. This. Was. Amazing. That lick led to another, then another, and soon I was moaning loudly as my little sister ate me out with a level of skill that I’d never experienced with anyone before in my entire life. My whole body was coming alive, tingling under the energy that Tori seemed to be pumping in straight through my pussy. As her sexy little tongue expertly teased my clit, I draped my legs over her shoulders, pulling her in closer.

“Oh, fuck. Oh, God, Tor, don’t stop,” I pleaded through my groans of pleasure. This was heaven, and I knew I couldn’t let this be the last time Tori did this to me. With every lick or flick of her tongue, I drew closer and closer to what I could feel was going to be a colossal orgasm.

Then, one of her hands left my breasts, and I felt her finger slip in between my folds, fingering my pussy as she licked at my clit. The sensation was too much, and before I even realized what was happening, the strongest orgasm I’d ever had in my life exploded through my body. I started quaking as my pussy convulsed, erupting as I squirted all over Tori’s face. My God, it was the most intense orgasm I’d ever had in my life.

When I finally came down from the high, I looked down at Tori, who had stopped to smile back up into my eyes. As I looked at the woman who just made me come so hard, my heart skipped a beat.

“You know,” she said, giving me a little wink, “if you want to help me, we can practice this more often, too.”

Now, I might be totally straight, but that was an offer I knew I couldn’t turn down. The entire weekend turned into a white-hot orgasm fest. By Sunday night, I didn’t even bother putting clothes back on. Any time I saw Tori, it was the perfect time for us to make out, which inevitably led to me screaming in pleasure as she delivered yet another scorching orgasm.

The first moment of awkwardness had to be the night Baxter came home. It’s pretty normal for us to have sex on his first night back from the firehouse. This night was no different. But I found myself really struggling to get aroused. Baxter tried kissing me, but eventually, I told him to move on because his kissing style was just turning me off, then he started groping me and undressing me, which wasn’t really hitting the spot either. I mean, after you’ve had someone show you how wonderful that can be, it’s hard enjoying it from someone clumsy and brutish like Baxter.

I did let him go down on me for a while, but even that was a chore. His stubble really bothered my thighs, and the way he licked and lapped at me didn’t have an ounce of skill compared to how Tori could do it. I guess being a woman, she just knows how to get a woman going. I tried imagining it was her going down on me, and that definitely helped, but eventually, I just pushed him off me and gave him a blowjob. At least that was still fun. As soon as he was leaking precum, I knew it was time, and I hopped on top of him. The sex itself was great, but the memory of how rough it all started dampened my mood.

For the rest of the week, I found myself sneaking off to Tori’s room again and again. Honestly, the hardest part was keeping quiet as she fingered or licked me to orgasm after orgasm every chance we got. We almost got caught a couple of times, but man, those orgasms were totally worth it.

About an hour after Baxter left for his shift on Friday, I found myself sitting with Tori on the living room sofa. She leaned over me, her hand buried in my skirt, stroking my pussy as we made out. I was absolutely in my happy place. A couple moments later, I was coming on...
