Cuddling with my sister turned into something more

So I’m 23 and my sister is 21. I am a total virgin and have never had a girlfriend. My sister and I are really close, we hang out together all the time, binge watch tv shows together and even play video games sometimes. My sister and I have always been comfortable being affectionate with each other. We often cuddle together when we’re watching tv shows. We also have grown up kissing each other on the lips. I know that may be weird to most people, but to us it’s was just normal sibling affection, nothing romantic. Lately, I’ve been noticing her more. Like, really noticing her. She’s got this beautiful curly red hair, and those light freckles across her face that just make her look… I don’t know. Cute. Gorgeous, really. I don’t know what changed, but every time we cuddle now or kiss goodnight, I feel something I’m not supposed to feel. It’s been messing with my head.

A few nights ago, we were catching up on the new season of Invincible in my room. We got under the blankets and laid side by side, like we’ve done a million times before. But this time, I couldn’t focus on the show. I was just aware of her—how close she was, how she smelled, how her hair brushed against my arm. I kept thinking I should say something, but I didn’t want to make it weird. She’s my sister. That’s a line you don’t cross… right?

After a few episodes, it was getting late. She turned to me and smiled, “I should probably head to bed. That was fun, as always. I love watching stuff with you, big bro.”

We leaned in for our usual goodnight kiss. Just a quick one on the lips, like always—but this time I didn’t pull away. I kissed her longer, without even thinking. It was soft, but definitely not our usual.

She pulled back a little and looked at me, confused but calm. “What was that?”

i panicked a bit. “Sorry,” I said. “I don’t know what came over me. I guess I’ve just been feeling really lonely lately. I didn’t mean to make it weird.”

She didn’t seem mad. If anything, she looked kind of… thoughtful. “It’s okay,” she said. “I don’t want you to feel lonely. I’m always here for you. If you need more affection or attention, just ask, okay?”

I nodded, not really sure what to say. “You’re the best, seriously. I don’t know what I’d do without you.”

She smiled and nudged me. “Aw, you’re such a sweetheart.”

There was a pause. I kind of whispered, “Would it be okay if we kissed a little more?”

She looked at me for a second, then said, “Sure. We can kiss as much as you want.”

We stayed lying there, just kissing. Nothing crazy—just soft, slow, kind of exploring. She even showed me how to use my tongue a bit, and we made out for a while. It felt surreal. I didn’t even notice what my body was doing until she looked down and said, “Oh… did I cause that?”

My cock was rock hard and poking her in the leg.

beyond embarrassed I said “Sorry… just a natural bodily reaction,”

She smiled gently and caressed my stomach.

“It’s okay,” she said.

“You don’t have to be embarrassed. I’m happy to take care of that if you’d like.”

“Really”

“Of Course. You’ve been lonely, and single for so long, you deserve some intimacy in your life. And I would love to provide that for you.” she said

“Oh sis, I’ve wanted you so bad, you’re so kind for this”. I said

“Let’s get these shorts off” she said as she pulled down my shorts and underwear, exposing my hard cock.

“Wow, so hard, I really did a number on you didn’t I.”

She gripped my cock and proceeded to gently kiss it on the head.she slowly covered my cock in sweet gentle kisses.

then she started to kiss it with tongue.

“Uhhh, Oooh fuck sis” I moaned.

She then took my whole length into her mouth, and began Bobbing her head up and down, giving me the best and most passionate blowjob ever. It was the best feeling I ever felt in my life. She was rocking my world. She looked me in the eyes and caressed my body as she sucked my cock. I was about to come, but I stopped her.

“I want to put it inside you, I want you so bad”.

She got up and slowly stripped her clothes off, and made sure I got a good look at her beautiful body. She got on top of me and slid my hard cock inside of her warm wet pussy.She passionately road me as we made out. I gripped her ass while she bounced up and down on my cock. It felt so fucking good.

I flipped her over and fucked her missionary for a bit while continuing to make out. then we got in the spooning position. I slid my cock back in, and slowly and passionately thrusted in and out of her.

My hand found her breast and I squeezed. She moaned and looked back at me, making eye contact, we were moaning and breathing heavily as we made love.

“yeah, that’s it bro. You can have this pussy anytime you want. You deserve this, Your sisters pussy is always available for you” She said while moaning.

“I’m going to come” I said.

“Come inside of me big bro, use your sisters pussy to make yourself cum.” I began to unload my cum deep in my sisters pussy.

“Yes that’s it bro, release it, let it go all inside of my pussy”. She said.

I finished releasing my load, and we just stared into each others eyes. We proceeded to passionately make out, exploring each other’s mouths with our tongues.

“I love you so much sis” I said

“I love you more than anything big bro”. She replied.

I love her so much and I hope this is the start of a lifelong romantic relationship with her. I really can’t see myself loving anyone else in this way except for her.
