Ass Play for Siblings

I took a careful bite of toast while getting my pussy fingered. I looked out the kitchen window where the world was passing as per normal. One of our neighbours was out walking her dog. Another went past the other way in a jogging outfit. Neither had the slightest inkling of what I was letting my brother do to me.

They all thought it was sweet, a brother and sister living together. Very familial. Very wholesome. They had no idea at all.

I loved it.

Even better than playing around with Logan was getting away with it in such blatant, naughty fashion. It was scandalous, really.

I got through about half my first slice of toast before Logan's magic fingers started affecting me too much. I leaned heavily against the counter, bracing with both arms, and stuck my butt out for more.

Then, just as it was getting good, he stopped. I turned my head in confusion, but Logan was already pulling my pants back up.

"Uh... what the hell?" I asked.

"Nothin' much. Just want you super horny for tonight."

"What? But... but... you meanie!"

Logan smirked. "Trust me. You're gonna need to be turned on. Don't want you reconsidering between now and then, do we?"

"I wooonnn't. Just finish me. C'mon."

He smacked my butt and walked away. "Tonight."

"Ugh. Jerk."

I finished my toast in a state of sexual frustration. And my panties were all damp now too. I'd have to go change before work. Given the state my brother had left me in, bringing a spare pair to work probably wouldn't hurt either.

****

Despite my initial annoyance with Logan's behaviour, my negativity gave way to anticipation and excitement through the day. I kept finding myself stuck in daydreams about what it was going to be like.

I was so tempted to sneak off to the bathroom and have a quick orgasm, but I managed to restrain myself. I didn't approve of Logan's methods by any means, but he was kind of right about how it was better if I stayed horny. It was much easier and more fun trying new things when I was all turned on and shit.

I'd soaked through my third pair of underwear by the time I got home. I was miserably horny, to the point where it almost wasn't even fun anymore. I was ready to straight up tackle Logan to the floor as soon as I saw him, but it turned out he wasn't even home yet. What the hell.

I decided I might as well take a shower while waiting for him. I was kind of gooey down below, and getting nice and clean felt like a good idea anyway.

I'd just gotten out and was wrapped in a towel when I heard Logan arrive. I went down to the entryway to greet him. He smiled when he saw me.

"How was your day?" Logan asked.

"Excruciating." I nodded toward our bedrooms. "Come on. Let's do this."

"How very romantic."

"Don't want romance. Want some goddamn butt sex."

"Well when you put it that way..."

I jabbed my finger at him. "No more teasing."

"Wouldn't dream of it. That was just to make sure you were all warmed up."

"And it worked. Probably better than you hoped." I jerked my thumb down the hall. "Now seriously, let's get moving."

"You don't even want supper first? I stopped and got some things. I was thinking-"

"I told you. No romance. Only butt sex." I started walking. "And if you don't follow me right the hell now, I'm calling your girlfriend and getting her to do it instead."

Logan jogged a few steps to catch up. "You know... I actually think you might."

"Don't try me."

"I don't plan on it. You think I want to miss my chance?"

I stopped short and Logan actually ran into me. I turned slowly to face him. "Your chance, huh? I thought you were only doing this 'cause I begged you?"

Logan shrugged awkwardly. The conspicuous smile on his lips gave away his true feelings. "I might have thought about what it would be like."

"Uh huh?"

"But obviously it was never going to happen. Not until you decided you had to try it."

"So it's still all my fault?"

"It's not... you're... it's..." Logan coughed and brushed past me. "We should probably get ready."

I tagged along, now the follower rather than the leader. "You were all acting like you were doing me a favour. Turns out you want this more than I do, don't you?"

"I wouldn't go that far."

"How far would you go, exactly?"

We made it to Logan's room. He stopped in the middle of his room. "Probably best not to explore that question," he said.

"Why not?"

"You know why not. Because... because some of the things we feel for each other... they aren't good. Some of the things I want to do with you sometimes... they're things we both agree we can't. Not without changing who we are."

There was an edge of desperation in his explanation. I softened, not that I'd really been upset to begin with. I just wanted to give him a bit of a hard time was all. He kind of deserved it.

But now...

I padded forward and slipped into my brother's arms. "Sorry," I said. "I do know what you mean. I probably shouldn't have asked you to, like, teach me butt stuff."

Logan wrapped his arms around me and rubbed my back. "Nah, it's all good. I'm actually glad you came to me. We should be there for each other. And... I kind of really like the idea of being your first again. It's one of my favourite memories, you know."

I smiled. "I was that good, was I?"

"That's... you know that's not what I mean. I don't mean about the sex."

"No, I know." I tilted my head up and brushed my lips across his. "That was special. Just like this is gonna be. Just us. Always us. That's what's important."

"I love you."

"Love you too."

Logan tugged at my towel. I lifted my arms and let him drop it to the floor.

He was totally hard inside his pants. While he removed his shirt, I pressed against his straining erection and contemplated it going inside me. And not just in my mouth like I was used to. No, this was for real. The thought made me shiver.

I helped Logan get the rest of his clothes off. That wasn't something I normally did, and the novelty was just one more thing to add to the excitement. Sure we were naked together a fair amount, but actually stripping one another in preparation for sex? Yeah. I liked the badness of it.

Logan threw me to the bed and I landed on my back in a fit of anxious giggling. He climbed in with me and I instinctively spread my legs to give access to my pussy. That was what I was used to, after all.

He grabbed my leg and hip and rolled me over. I complied and got comfy on my tummy, sticking my ass up slightly once I was settled.

"You're gonna make sure it doesn't hurt, right?" I asked.

"Do my best. I can't promise absolutely for sure. Some of it depends on you."

I squirmed nervously. "I don't want it to hurt."

"I know. I'll go slow. Don't worry."

His hand pressed on the small of my back. Its familiar weight and warmth gave a sense of comfort and security, and I gradually went still.

It was Logan. My big brother. I could put my trust him. He'd never let anything bad happen to me.

He rubbed my back for a few minutes until I was soothed and becalmed. Then he went lower and massaged my butt. It didn't have nearly the same calming effect, but I definitely liked the naughtiness of it.

Logan gradually circled in on my butthole. I tried not to tense up or flinch when he brushed it with his thumb or even pressed against it a bit. I wasn't successful at first, but I got used to it after a while. That was the point, I supposed.

That stuff was basically expected, more or less. What I didn't expect was for my brother to then spread my ass cheeks and drag his tongue along the cleft between them.

I squealed in a very undignified manner. "Hey! You can't do that!"

Logan licked again. "Why not?"

"It's... it's dirty."

"You're all freshly showered, aren't you?"

I bit my lip and privately admitted that yes, I had cleaned myself well in preparation. I'd spent quite a bit of time on my ass, in fact. Even rubbing a finger over it repeatedly, trying to gauge how it would feel to actually shove something up there.

"Well... yes," I said.

"Then what's the problem? It's just skin."

"Still dirty," I mumbled.

Logan gave me a light slap on the butt. "You just worry about relaxing. Let me worry about what you taste like."

It was impossible to relax fully while getting licked back there. It was such a confusing feeling. Bad and dirty, but also, maybe, kinda nice. Kinda good.

I grabbed Logan's pillow and pulled it beneath me to hug. I was conflicted and horny, and maybe slightly ashamed. Only slightly, mind you. Mostly I was simply uncertain of myself and what we were doing. That, perhaps more than anything else, was what bothered me. I was used to always knowing exactly how I felt about us. Our sibling bond was a constant in my life, and there was a chance I'd jeopardized that.

My brother's steady licking and tonguing of my asshole slowly shifted my opinion of it. I'd assumed there was no way I could get used to it, and that my initial thoughts and worries would remain. That turned out to be as foolish as any time such assumptions are made.

I was coming to find out that having my butthole licked could be a fun and pleasant experience, provided I was sufficiently patient. It wasn't as incredible as some pussy action would have been, in a purely physical sense, but its dirtier nature and the vague aura of wrongness kind of made up for that, in their own ways.

"Why do I feel like you're enjoying this more than I am?" I asked.

Logan paused. He replaced his tongue with a couple fingers, gently probing at my spit-slick entrance. "How do you mean?"

"I mean you're like a puppy. You just keep going. You know the point of the exercise is to get your penis in me, right?"

He laughed softly. "Well... there's a possibility that my baby sister has a totally amazing ass... and this may be the only chance I have to play with it as much as I want..."

"Goddamn, dude. Maybe this isn't such a good idea after all. I mean... it's not really s'posed to be about fulfilling fantasies with each other."

"You're not backing out now."

"No, I'm not. I'm just saying, like, maybe we need to think about it a little more? I dunno."

Logan planted a kiss on my bare ass cheek. "Too late for thinking, dear sister. We're doing this."

"But-"

"Exactly."

"No, not that kind of 'butt,' you goofball. Just... just promise me this is gonna be ok. It's not gonna change anything."

"Promise. It's just gonna be one time, right? Just so you know what it's like. I plan to enjoy it, is all."

Truth be told, I liked that my brother was apparently so enamored with my ass. I liked that he had some secret little fantasies involving it. There really wasn't any harm in indulging him, as long as we kept our main goal in mind.

And it was only once. There was no harm in only one time. Right?

I gasped as one of Logan's fingers actually pushed past my outer defenses and penetrated my tight hole. It didn't hurt or anything, it mostly just surprised me. Perhaps it shouldn't have, but it did.

"Your finger..."

"It's in your butt, yes," Logan said. "Is that ok?"

"It's... yeah. I guess it is." I squirmed a bit. "It's weird, but not bad."

"That's a good start." Logan withdrew, then hopped off the bed. "Probably better lube you up properly before we go too far."

"Probably," I agreed.

I knew enough about the mechanics of anal sex to know that lubrication was vital.

The lube was a tiny bit cold for comfort as it was drizzled down my bum cleavage, but the slipperiness felt nice when Logan resumed playing with my butthole. His finger slid in even easier the next time. Soon he was gently finger-fucking me.

I was fine with one finger. That I could handle. I felt him trying to slip a second finger in, and that was too much for me.

"Hey! One at a time," I said.

"You can do two."

"I can't. My butt's only little."

"Would you just trust me, Kelse? Hm?"

"That's not fair."

"What? Asking you to trust me?"

"Yeah. That's cheating."

Logan patted my ass cheek with his free hand. "Just trust me."

"Goddammit."

He knew asking me something like that meant I had to do it. Just like I'd known that he'd say yes if I asked him for sex. Granted, it turned out he was even more into the idea of fucking my ass than I would have guessed, but still.

Stay calm. That was important. No matter how worried I got, I had to stay calm. Logan wouldn't hurt me. I knew that.

I felt a bit of a stretch, then his second finger was in. Not so bad, actually. A little uncomfortable maybe, but even that was fading after only a few seconds.

"You're so tight," he said.

"Of course I am. Butts are tight. That's what they do."

"Just sayin'."

The anal fingering was really getting to me. I wasn't sure if it was the physical sensations themselves, or rather the vulnerability and sensuality of remaining in my severely exposed position and being so casually toyed with in a new and unfamiliar way.

"You should do it now," I said softly.

"What?"

"Fuck me. In my butt."

"Are you sure? I was kinda planning on taking it slower than that. Maybe doing some-"

"I feel like you'd make this last all night if you could."

"Maybe."

"I think I'm ready now. Your fingers don't hurt. I want to feel your cock."

Logan hesitated. "I'm not convinced you're actually enjoying this yet."

"I'm not sure quite what to feel about it yet. Hence getting to the real thing."

"Well..."

"Dammit, Gun. Stick your penis in your li'l sister's butthole already."

"Mmm. Well when you put it that way..."

I wiggled my hips. "Unfairly alluring. I know."

Logan rubbed in some more lube, which I appreciated. Best to err on the side of caution.

My heart beat so hard as he pressed his hard cock to my ass. I was still nervous, but it was different than before. It was the same kind of jittery anticipation as when it had all been hypothetical in my mind rather than something I was actually going to have to go through with.

Yes, I was excited again. Properly excited. Unconcerned-for-my-anal-wellbeing excited. I almost didn't even care if it hurt, or if I didn't like it, or whatever. I was going to do it. I was going to be brave as fuck and find out.

There was a moment where Logan just wasn't going to fit, it wasn't going to happen. I was so disappointed. Happily, it was only a moment.

My tight little hole stretched, and flexed, and resisted, and eventually surrendered to let my brother in. And it was amazing. I had no idea why fingers were just kind of ok while a penis was truly spectacular, but it was, and I loved it.

"Ooh," I cooed. "I kinda like that."

"Do you indeed?"

"I do. It fits much nicer."

"It... what?"

"Shut up. I don't know. It just does, ok?"

It was true. Fingers hadn't done the job. They weren't the right size, or shape, or... something. They just weren't right. Logan's dick was. Maybe because of who he was, maybe just because cocks were nicer than fingers. I didn't much care. My bum was getting filled up with brother-cock, and it was doing all sorts of special things to my insides.

Logan's hips bumped me as he hilted firmly inside me. My ass was as full of him as it could possibly be.

"Stay there a sec," I said.

"Right here?"

"Yesss."

"Dang you're weird sometimes. I gotta move a bit or-"

"Just hold still for a minute. That's all. I just wanna feel."

My brother, as always, indulged me. I squeezed my ass, and wiggled a bit, then rocked back and forth a little. I was thoroughly penetrated.

I really did like the feeling. It wasn't quite so blatantly pleasurable as vaginal penetration, but it was filling, and comforting, and sexy in a bit of a subtler fashion. It was different.

"Ok," I said. "You can move now."

"Oh can I?"

I ignored his sarcastic tone. "Yes."

Logan couldn't get too snarky with me, not when he was totally buried inside me. I sensed his desire to say something else, but he restrained himself.

Instead, he grabbed my hips and began gently thrusting. My ass gripped his cock as he pulled back, which was quite an interesting feeling for us both, and continued to resist slightly when he pushed back in. That tendency to fight back diminished as I grew accustomed to getting butt-fucked.

Logan's thrusting became smoother and smoother until it felt almost like regular sex, albeit in a different hole. I loved how easily I could apparently take it when properly warmed up. I'd halfway assumed I just wouldn't be able to deal with proper fucking, that my body wouldn't be ready for it with so little experience. I'd been wrong.

"Harder," I whispered.

I thought he didn't hear me at first, but his movements gradually ramped up.

"Like that?" he asked.

"More."

"Really?"

"I might need you to slow down again. But just... I want to see what's like."

"Of course you do."

Logan gave my butt a quick, sharp smack, which in my state only made me arch my back and hiss in wanton pleasure. I was being such a bad girl. So naughty. So butt-slutty.

I seem to have convinced my brother that I was serious. He really began to let loose and pound my ass. It kind of hurt a little, just the sheer force of it on my formerly virgin bum, but I even enjoyed that small discomfort for the raw, animalistic sense of depravity and excess it added.

Logan grunted and panted from behind me. The sounds he made were a decadent symphony to my ears. He was clearly lost in lust, just as I was.

We were quite a pair. A brother and sister engaged in wild butt sex. God how I loved it.

"Fuuuck," Logan moaned. "I'm gonna cum."

My eyes rolled back. That was too delicious for words. "Yesss," I hissed. "Cum in me. Cum in my ass."

His fingers dug painfully into my hips. "Don't say that."

I grinned. "Do ittt. Cum in your little sister's tight little bum."

"Daaammmn."

His cum was scalding hot inside me. It was initially a shock, then just fucking hot.

"Mmm," I moaned. "That's right, bro. Give your sister's ass all that creamy good stuff."

He shuddered as he was finally spent. "Dammit, Kelse. You know what talking like that does to me."

"Well duh. S'kinda the point."

I experienced a surge of disappointment as Logan withdrew. I missed the comfy full feeling in my backside already.

On the other hand, it was probably just as well to end when we did. I ached in a soft, dull kind of way. It could easily turn into an unable-to-sit-down kind of thing if I'd let things get any crazier.

Logan patted my bum, then lay down beside me. I rolled a bit to face him.

"You didn't cum, did you?" he asked.

I shook my head. "Nope."

"Sorry."

"That's ok. I don't really mind. That wasn't the point of the exercise."

"Maybe not. Would have been nice though, wouldn't it?"

"Of course it would. Cumming is always nice."

Logan laid a gentle hand on my breast. He idly swirled his thumb around my nipple. "Would have been nice too if you had a really good experience the first time," he said. "I don't think I did as well at that as I hoped."

"What? Because I didn't have an orgasm?" I shook my head, then leaned in and kissed him on the nose. "It was wonderful, Gun. Honestly. It was just exactly what I wanted."

"Really?"

"Yes, you silly brother you. I figured out I like it in the butt, if done properly. Like, really like it."

He grinned. "I see. Well then... we might have to try it some more and see if we can get you to cum too."

"'We,' huh?"

"Purely for testing purposes of course."

"Right. Of course. Even though this was only gonna be one time?"

"Well... you know. I don't think it would be right to leave you only half knowing. Getting off is important."

I examined my brother's face from under half-closed eyelids. This had been one of the risks, I supposed. That one of us would get a taste for more. Sex one time was one thing. Sex many times was something totally different. Much less manageable.
