Birthday Boy 23

Author's Note: All characters over eighteen.

I woke up with company in bed. I was confused for a moment as my sleep-addled brain processed Mom's smiling face right next to me. I started piecing things together pretty quickly as my eyes roamed downward and took in the sight of her nude body, totally unclothed other than a pretty pink collar that just said 'Mommy' on it in big, shiny letters.

I groaned softly. Just the sheer image of her in a naked state lighting a fire in me first thing in the morning.

"Happy birthday, baby," Mom said, just as I recalled that fact myself.

It was, in fact, my birthday. Which, if I could possibly dare to dream, meant that on my other side....

"Yeah, yeah. Happy birthday, Sieg," Elsie grumbled.

She wasn't truly annoyed, I had plenty of experience with that side of her, being her only brother and all, but she also wasn't about to be as openly cheerful about today as our mother.

"Thanks," I said, still rather bleary but waking up quickly as the potential of the morning started to hit me. My eyes tried to do a lovely peruse down my big sister's body the way they had with mom's a moment ago, but I had to frown instead. "What's with the clothes?"

Elsie rolled her eyes.

"We thought it would be nice for you to have something to unwrap," Mom said.

"Mom's idea," Elsie said. "I said there's no point, you just want to stare at tits anyway."

"Hey now!" I protested. "I like other parts too." I plucked gently at the shirt my sister wore, then turned the other way to tweak Mom's nipple. "Both approaches have merit," I said magnanimously.

I could practically hear Elsie's silent scoff, but I was more interested in the faint gasp from Mom. I teased her nipple a little more in response. Was she already horny? I was certainly well on my way.

It was so hard to know what either Mom or Elsie really thought or felt. I knew they liked some parts of this birthday surprise or they wouldn't have done it the first time, let alone sneaking it on me again this year. I still couldn't believe it had actually happened a year ago, and I was getting very smiley already that I had another chance to play now. A year was a long time to wait and wonder.

Mom's tits were an absolute magnet for me. No surprise there, really. She had fantastic breasts, made all the more obvious when they were right there practically in my face and everything.

One of the very few things that could distract me, as it happened, was Elsie slipping under the covers. I'd just been thinking my sheets were probably in the way at this point, separating me as they did from my mom and sister. There was something magical though about my big sis crawling under them with lewd intent.

"So eager," Mom teased Elsie.

"Not even!" Elsie protested. "But you said we have to give a morning, blowjob. So what, like I'm supposed to just wait around forever?"

Mom winked at me. "She's so broken up about it, isn't she?"

My response was an incoherent noise, as Elsie's tongue found my cock. I slept nude most nights, not for any particular reason. This morning it had the benefit of letting my sister have easy access.

"I'm just being efficient," Elsie said. "Now get down here already."

Mom grinned at Elsie's command and gave me an apologetic shrug. "As the lady orders."

Mom's boobs slipping away left me wistful, but two warm forms under the blankets with me and an equal pair of wet, eager little tongues made for a trade I'd take in a heartbeat.

I wasn't getting a blowjob exactly. At no point did Mom or Elsie take me in their mouths. It was all just tongue-play, or sucking on either side of my shaft, up and down, sharing me equally.

There was only so long I could go before needing to see them better. I threw back the covers--tossed them off the bed entirely, in fact--so I could gaze at my mom and sister sucking on me. Elsie flushed softly in a mix of embarrassment and annoyance, but didn't stop licking. Mom paused long enough to bite her lip and give me a horny look, then she was right back to it as well.

Mom drew the eye much harder at the moment, what with her outfit of a slutty collar and nothing else at all. Her ass was a thing of beauty, even if I could only see it at an oblique angle. Her cleavage was bountiful, and her tits pressed so softly on my thigh.

Elsie was still dressed, but I couldn't help watching her too. There was just something about the way she looked at me while nibbling on my cock. It was the kind of look I never got from my sister at any other time of the year, and for some reason I craved more of it.

I moaned louder and more often as they kept licking and sucking on me. My body tensed and my toes curled, and before I knew it I was cumming right between their faces.

Mom, in probably the sluttiest display I'd seen from her, immediately opened her mouth wide and stuck out her tongue, somehow clearly smiling despite the horny expression. Elsie flinched back a little as a shot of cum struck her cheek, but after her initial response did actually move back in to let more hit her.

"Well you sure made a mess now," Elsie said. "Hope you're proud of that."

I couldn't help smiling goofily. "I think I am, actually."

"Don't be petulant, sweetie," Mom said, giving the side of Elsie's face a few cute little licks. "You knew that was going to happen."

Elsie rolled her eyes, but allowed Mom to lick all the cum off of her. "So embarrassing, Mom," she grumbled.

"And I always will be," Mom assured her.

"I'm not licking the cum off of you," Elsie warned.

"That's ok," Mom purred. "I might leave it on."

"So embarrassing," Elsie repeated with a sigh.

Mom just giggled and finished a bit of cum by Elsie's lips, taking the opportunity for a soft, quick kiss too. It continued to surprise me what my sister would go along with, despite her complaining. She even seemed like she kind of enjoyed the kiss.

"Alright!" Mom said, with hardly a moment to rest. "Time to unwrap your present!"

I raised an eyebrow as Mom bounced from the bed and snagged her phone which she had left conveniently near to hand. It took me a moment, and Elsie begrudgingly crawling closer, to realize what she meant.

I grinned and cautiously put a hand on Elsie, making sure she was going to let me. Mom stood primly by waiting to take pictures of the moment.

"You two are so weird," Elsie said.

"What did I do?" I protested.

"You want to undress your sis-ter," she said, like I was an idiot for not understanding. "And Mom's there like this is an event for a family scrapbook."

"Memories are memories, darling," Mom chastised lightly.

I had my hand fully up Elsie's shirt, and she hadn't moved a muscle. "I do want to undress you," I admitted. It wasn't like that was any kind of secret. "Is that ok?"

She shrugged. "It's your birthday," she said, as though that was enough of an answer.

I lifted her shirt up, exposing her tummy. "Sooo... it's ok?"

"Yeah, Sieg. Jeez. So embarrassing, the both of you."

I really felt like that was unfair. It was Mom snapping pictures as I reverently took Elsie's clothes off. I didn't know what I was doing to be so embarrassing.

Besides, Elsie's skin was so warm and flushed as I slowly got her naked. She was enjoying it too, to some degree. Probably not as much as I was, but that would have been hard to beat anyway. Despite just cumming, I was fully hard and horny again by the time I had my big sister naked.

Mom giggled and kissed me full on the mouth. "Happy birthday," she said unnecessarily. "You two take your time. I'm going to get breakfast ready."

She padded off nakedly with the sort of hip-rolling stride that inexorably drew the gaze to her ass. I knew from past experience that Mom could do that when she wanted to, but mostly chose not to. I fully sighed and appreciated the sight while I had the chance, especially while her ass was fully out and exposed for my viewing pleasure.

Mom's full, juicy booty was a heavenly sight all on its own, in particular when she was making sure to walk sexily for me. My jaw dropped when I realized there was even more she wanted me to see. A glittering red gem buried right in the middle. I only barely had time to register that my own mother was wearing a butt plug, and had specifically wanted to show it off to me.

I knew that shouldn't have been all that much of a surprise under the circumstances, but somehow it was. Even on my last birthday Mom hadn't been interested in anything anal. I didn't know what this meant, but it had my mind whirring.

"Did... did you see that?" I asked.

Elsie snorted softly in amusement. "Yeah, I saw."

I was glad to note that when I glanced at her, she was staring just as fixedly at the doorway as I'd been, even though Mom was fully out of sight now.

"With the butt plug and everything?" I clarified.

"Everything," Elsie confirmed. "Mom can be a little embarrassing, but damn is she hot."

My eyes bugged out a little hearing her say that. "Oh really?"

"I have eyes, bro."

"Right, right," I said. "I thought she didn't like butt stuff though."

"Yeah, same," Elsie shrugged. "She spoils you though. You know that, don't you?"

"... generally? Or specifically for, uh, birthday stuff?"

"Both. Mostly sex, I meant." Elsie thought for a moment, then let out a small giggle. "Like, I know I'm going along with this again, but I still can't even believe she did all this for you last year too."

I turned my focus back to Elsie, and the way she was fully naked and practically in my lap. "You, uh, might kind of spoil me too," I said. "On occasion."

"Yeah, well, you know. Cheaper than trying to buy something nice for you, isn't it?" she said evasively. "And, like, I do want you to be happy. Even if you're a horny little freak sometimes."

I ran my hands up Elsie's body to her tits. She once again didn't move an inch while I felt her up.

"Very nice of you," I said.

"Uh huh."

"You're kind of like the best big sister ever, you know."

Her cheeks pinkened slightly. "Easy to say while you have my clothes off."

"It is, isn't it?" I said happily, taking the opportunity to fondle her ass some as well.

Elsie let me feel her up some more, taking it all in stride, before finally bouncing away from me.

"I need a shower," she decided.

"Why?"

"Because someone decided to cum all over me."

I scoffed. "Only on your face. And Mom cleaned you up anyway."

"A tongue-bath is not a real cleaning," Elsie declared.

I shivered pleasantly at the mental image of Mom tongue-bathing her properly. All over. Or bathing me that way for that matter....

I was disappointed for Elsie to leave, but still quite happy to watch her walk away. She had a similar effect to Mom in that regard. Her butt was smaller and tighter, and just as hypnotizing in a subtly different way.

Elsie paused in the doorway. "You can come too, if you want," she said. "If you need to clean up or whatever."

She was gone without waiting for an answer, but I smiled and darted after her eagerly. I wasn't going to push my luck with Elsie and risk her actual displeasure--not just her big sister aloofness, which was a purely normal thing--but if she was inviting me, then I was most certainly accepting.

Elsie only just had the water turned on when I showed up behind her. She smirked at my quick arrival, then a moment later stepped under the spray while watching me with an expression that matched Mom's horny eyes from earlier. A visual invitation even stronger than her verbal one.

I wouldn't have been able to enjoy myself half so much without little confirmations here and there that Elsie enjoyed this too, even if it wasn't as much as I did, and even if a lot of this was still just her grudgingly doting on her little brother. She really was quite good to me generally, all things considered. Most siblings I knew had way, way less patience for each other.

I hopped in with Elsie, and just enjoyed the experience. I honestly wasn't sure whether I liked washing her better, or her washing me. Both were sensual, calming, and arousing in their own ways.

I was so very hard, and particularly enjoyed getting to press up again my sister from behind, lodging my cock in her butt crack while washing her hair for her. She melted for me as I massaged her hair and scalp, seemingly oblivious to my erection against her bum. Granted, I was well-behaved to the extent that I could be. I didn't even feel the need to grind on her. I just liked holding my cock between her ass cheeks.

We were both as clean as we'd ever been in our lives by the time we finished. I'd run my hands over every inch of my sister, naturally, but she was just as thorough for me in return. Of course I loved her washing my cock and balls for me, but even my back, shoulders, thighs, and especially my hair were all soothing and sensual experiences too.

I felt so fresh and clean, and still very horny by the time we stepped out to dry off. I was much faster at toweling off, and instead of letting me mess around some more, Elsie shooed me off to go bug Mom while she finished up.

I was reluctant to leave my sister, but eager to go see my mother, and the two forces roughly canceled out.

My breath actually caught in my throat as soon as I stepped into the kitchen. Mom had added an apron to her lack of outfit, and stood facing the stove. She looked absolutely sexy from that angle, and that was even before I got close enough to examine her butt plug.

Mom turned just enough to show off her Mommy collar to full effect, and favoured me with a beaming smile.

"Getting hungry, baby?" she asked. "I've got breakfast almost ready."

"Unf, yeah," I said, unable to hold back my reaction. "I could eat."

I pattered closer, approaching almost as I would a skittish cat, soft and careful. I didn't need to worry. Mom was smiling and even wiggled her bum a little, enticing me in. She wanted me getting up close just as badly as I wanted to be there.

It was crazy how hot Mom was. Like the sort of thing that could mess with a guy while going through vulnerable and hormonal times of life. I wasn't sure whether it messed with me more or less knowing that at least a few times in my life I got to do something about those feelings and urges I had toward her.

She even raised herself on tiptoe a bit as I approached from behind, lifting her big, beautiful bum for me. I groaned as I put both hands on it, getting to feel up my mom's booty and knowing she was encouraging every little touch.

It was an ass that dreams were made of. In my case, fairly literally. To caress and fondle it to my heart's content was an absolute treat and a delight. Soft and supple, yet pleasantly firm at the same time. The perfect balance of give and resistance, and oh so wondrous to lift and spread.

I allowed myself the luxury of trapping my cock between Mom's ass cheeks, finding significantly more room to lose my erection in her booty than in Elsie's. I loved my sister's butt just as much, but the two backsides were very different and I fully intended to appreciate the most out of what they each had to offer.

My cock bumped up against the plug in Mom's butt a few times, which finally guided me back toward exploration rather than just grinding on her. I knelt down behind Mom, face to face with her big booty, and the shiny butt plug nestled within. She bounced up on the balls of her feet a couple times in what appeared to be unconscious excitement, though could very easily have been deliberately for my benefit again.

"Wearing a butt plug, huh?" I said, poking the toy with interest and fascination.

I watched and felt the way the plug could wiggle inside her, and could be pressed a little deeper or pulled slightly outward without actually being dislodged at all.

"Thought it might be a good idea," Mom said, sucking in a tight breath as I pulled her plug harder and watched her little hole stretch out around it. "I know you wanted anal last year and my bum just wasn't prepared for that."

"I mean... it's impossible not to want your butt once I've seen it," I said.

"Baby...."

"But I know you're not really into that stuff, and you really don't have to just for me."

Mom hesitated, moaning softly as I played some more with her butt plug. "It's true that I've never been into it. Historically, I mean. I think it's possible though that it was important to me to feel safe and loved and be able to trust someone entirely if I was going to let that person mess around with my bum."

I looked up at her. She looked right back at me over her shoulder, biting her lip rather cutely.

"You're saying...."

"You know how much I love you, Sieg," Mom said. "I've been... training, I suppose you'd call it. Just in case."

I planted a big kiss on Mom's butt cheek. "Mom... that's like... like maybe the hottest thing anyone's ever said? And, like, kind of beautiful too. You really mean it?"

"Every word," Mom said firmly. "I feel like I can try new things with you. Even if just this one day. And I mean after all, it is your birthday. If there happens to be, perhaps, any special things you'd like to do."

"Unf." I buried my face in Mom's thick booty for a moment. "I might be able to think of one or two things," I admitted.

She reached down to pat my head. "Good boy," she whispered.

I shivered and hid my face in her ass-cleavage even longer. I'd assumed I couldn't desire my mommy any harder. I'd been wrong.

I stayed right where I was for just as long as my lungs could hold out. Drowning in my mom's comforting booty was a dangerous game. I could probably suffocate there and not be too bothered about it.

Horniness came to the rescue somehow as I made a few attempts at pulling Mom's butt plug free with my teeth. I wasn't successful, but at least I could breathe while trying. She whimpered cutely as her bumhole flared out around the width of the plug, but I couldn't quite get enough purchase to pop it free. It was fun to try though.

My fingers did the trick easily enough, once I gave up on my mouth. My eyes widened as Mom's butt just kept opening more and more, before finally releasing the toy to my possession. I'd initially expected something fairly small, then perhaps something medium sized when I couldn't free it with my teeth alone. This, however, was downright large. Not a ridiculous size or anything, but bigger than I ever would have expected from my mom.

"Mommy," I breathed, cradling the plug in both my hands and staring at it with awe. "It's so big."

"Mmm, I know, baby. I wasn't going to ever wear anything that large, but I kind of got too used to the smaller one I had. And your sister did kind of insist."

"Elsie did?" I asked. "She wouldn't. Would she?"

"She did," Mom confirmed. "When we were planning your birthday. She gets opinions about these sorts of things, you know."

My heart felt oddly warmed to realize how much Elsie cared for me. I knew she did, but she often only ever showed it in roundabout ways. Taking care of me on my birthday was about as direct as she got, and even then she probably would never admit to something like helping Mom anal train for my benefit.

"I've got the best sister," I said. I planted a kiss right on Mom's butthole, which remained gaped open a little from her plug. "And the best mommy, of course."

"Ooh, baby...."

I kissed her cute asshole a few more times, then dove straight in with my tongue. If I had the chance to eat my mommy's butt, I absolutely was going to take it. I slurped away happily on her while listening to her soft moans and feeling her tremble a little more with every lick.

The soft pattering of Elsie's feet reached my ears even with my hearing somewhat muffled by Mom's ass. I wasn't about to pull back even long enough to acknowledge my sister, but I knew she was there. I just kept nomming on mommy-booty.
