Family Diaper Rules

I couldn’t really describe my home as normal. With nearly 22 I’m living with my Step Mom (though I just call her Mom), who has an unusual style of parenting. To be honest she is kind of a pervert, but nobody calls her that, because she‘s so confident and pretty - and confident, pretty people are usually not called perverts. At most they „have unusual taste“ or „are a little kinky“.

And oh, was she kinky. One time, when I was 19, she somehow put me back into diapers, got me breastfed and sucking pacifiers again. That was a whole thing. But I‘ll get to that in a second.

Her daughter, my then 21 year old Step Sister, is her spitting image and is hot as hell, but also a complete fucking slut. She always wears short skirts, no panties and no bra. She is constantly sending out nudes of herself and is also honestly so much fun to be around. We often joke that we could have sex with each other at any given moment and Mom would probably let us, but we're close friends and would never want to do something that seriously fucked up our friendship.

Anyway, here’s how all this stuff I mentioned happened. It pretty much started as a regular day.

Me and my Sister were home alone one day. We were watching TV in the living room together, both dressed in our pajamas. I had a pacifier in my mouth because I like to suck on it sometimes (although at that point in time, I did it like once a week and almost always alone in my room), and my Sister was sitting on the couch playing with her phone, wearing her pajama shorts, a tank top and no bra and no panties of course. Once in a while she would tell me how much I looked like a baby, but I didn’t care and knew she was just messing around. I knew she wouldn’t tell Mom and that was all I really cared about.

I noticed her nipples were erect and kept glancing. She eventually caught me looking at them, so she casually took off her top, revealing her round, perky tits and said: „I was actually hot anyway.“

She nonchalantly threw it next to me on the couch and continued playing on her phone.

We would sometimes do that. Tease each other to test if we were true siblings and really not getting turned on by this sorta stuff. And we weren’t, usually.

I tried not to look too much and kept watching the TV. I was watching Breaking Bad and Haley had agreed to watch with me but was only on her phone as was typical for her.

„Such a little baby“, she kept saying, „Should be sucking on my fucking tits and not your stupid pacifier.“

„Fuck you“, I said and she smiled. I was still a little embarrassed about sucking my pacifier in front of her, but I just liked it too much to not do it.

„Can you imagine doing it for real though?“, she asked.

„What?“, I asked, „Sucking on your tits?“

„Yes“, she said.

„Yeah I can“, I said, „Would be awkward as hell.“

She shrugged.

„Yeah, probably“, she replied, „But not hot though, right? You’re my brother, so it’s literally impossible for you to find this hot.“

She wiggled her tits and looked at me.

„Yeah, no shit. I‘d feel like a pervert sucking on my sisters boobs“, I said while trying not to imagine it too much.

Meanwhile, Walter White and Jesse Pinkman were cooking meth in the New Mexico desert.

„Well“, she said, „You‘re only a pervert if you enjoy it, so show me that you don’t.“

I hesitated and really thought about it for a moment. I felt the real test was if I was gonna go for it.

„You’re the fucking pervert on this couch“, I said, „I‘m minding my own business over here.“

Haley didn’t really seemed fazed by my reaction. She just patted her lap.

„Lay down at least“, she said. Again, I hesitated and looked at her. Shoulders upwards as best I could. Her look softened.

„Come on. It’s really not to prove anything, I promise. Just because I love you and care about you.“

Suddenly she sounded like she wasn’t completely joking and I actually didn’t mind laying my head on her lap.

So I did.

I was on my back and watching the TV. Her thighs were warm against my head and neck and she softly caressed my hair.

„Can I try?“, she asked and pointed at my pacifier.

I looked up at her and she looked very curious.

I thought for a second and said: „Go ahead. Maybe it calms you down and finally makes you shut up.“

She giggled, pulled the pacifier out of my mouth and placed it on her tongue.

She smiled and sucked on it while caressing my head.

„Mmm, love your spit", she teased.

I looked up at her and her tits were nearly in my face.

„Wanna give em a suck?“, she asked through the pacifier.

She leaned forward to let her tits hang down into my face. Her nipples were hard and nearly touching my lips. I chuckled and looked up at her. Hopefully she didn’t notice that I was kinda nervous. She seemed pretty serious and nodded.

„Come on, I‘m in the mood“, she said, „may be months before you get the chance again.“

I laughed, but I was also very tempted. For a moment there was only the sound of the TV.

„You're really fucking weird“, I said and she giggled.

„So are you, now come on.“

I shrugged and took a deep breath.

„Ok then. Screw it.“

I slowly grabbed her tits, one in each hand, and put my lips around her right nipple. She giggled and kept caressing my head.

„That a boy. Milk me good.“

I sucked on her nipples and she on the pacifier.

It felt kinda odd, but also kinda nice. Surprisingly, I didn't feel like a pervert, so I figured that this was fine.

Her tits were soft and felt amazing in my hands. I gently squeezed them and sucked on her nipples. I closed my eyes and enjoyed myself.

After a minute or so, I opened them and looked up.

She was smiling, with my pacifier between her lips and looking down at me.

„So?“, she asked.

She took my pacifier from her mouth, held it between two fingers and played with it a little, then stuck it back in her mouth.

I released her tits and her nipples were wet with my spit. I wasn’t sure what to say.

„What do you mean?“

„My tits. How‘d they taste?“

I thought for a moment and went with the safe option.

„Actually really disgusting.“

She smiled and looked at me, then at my crotch. Her hand slipped between by legs.

„Hey! Don’t check my dick“, I said, pretending to be embarrassed. I actually didn’t mind. She smiled contently as her hand slipped off of my soft manhood.

„Alright“, she said, as she was taking out the pacifier, „Glad you’re not a pervert.“

She laid it on my lips and pushed into my mouth. I let it slip in. She called me a baby once more and I pushed her gently before we laid back comfortably on the couch and resumed actually watching the series.

For once, she put aside her phone and joined me watching the show. After a while, she rested her head on my shoulder and sighed.

„Hope you’re getting ready to suck my dick, so I know you’re not a pervert either“, I said.

She looked confused, then she laughed and punched me. I always loved how confident I felt around her to say those kinda things which I usually couldn’t.

„Fuck you“, she said, „That wouldn’t even count, everyone gets turned on by sucking dick. It’s biological.“

She cuddled up to me again and kept watching TV as her boobs were pressed against my upper arm. I was calmly sucking on my pacifier and enjoying her closeness.

Some time later she took some pictures of her boobs. Probably to post on her Twitter (fucking X) or for her BeReal or something. Then we continued cuddling and watching the episode and another one after that.

„I gotta go now, I have a shift at six“, she said after about another hour of Breaking Bad and laying around, „Daddy Capitalism is calling and he wants me to work.“

She was a waitress at a restaurant downtown and by the looks of it a pretty good one. Her tips were always through the roof. Although that could have other reasons too, admittedly.

She kissed my forehead and got up. She put on her top again, grabbed her phone and left the living room.

Some minutes later, I heard her leaving the apartment and I was home alone. It was another hour before mom would come home from work. So I was sitting around alone as I would probably often be the next few weeks as it was Friday before summer holiday.

For the lack of a better thing to do I kept watching TV and started thinking about Haley‘s boobs again. How good they felt and tasted and how hot she looked with that pacifier in her mouth.

It didn't make me feel like a pervert or gross or anything, and it did kinda turn me on. So I decided to jack off and just forget about it afterwards.

Since the house was empty, I decided to just do it on the sofa. I was naked, laying on my back and slowly rubbing my hard dick. I was sucking on my pacifier imagining it was her nipple. It didn’t take me long to cum. It felt so good and I couldn’t stop moaning as I shot my load. However, I had a little trouble aiming and some of my cum ended up on the cushion. I didn’t really worry about it though since you could barely tell, so I just cleaned myself up a little and made myself some mac and cheese in the kitchen.

My mom came home 20 minutes later and asked me if I had had fun. I was a bit confused by her question and she clarified, „The cushion looks like a Jackson Pollock painting.“

I almost choked on the cheesy macaroni I was stuffing into my mouth. But she just laughed and said: „Well, I guess you’re a young man and these kinda accidents are bound to happen.“

She sat down next to me. She was wearing a black dress, as she sometimes would at work.

„I think we still should talk about this though“, she said.

„Oh, ok“, I said, embarrassed.

„First of all, I love that you’re open enough about your sexuality that you’re just jerking off in the living room, honey. That’s great, honestly, and I don’t want to restrict that in any way. But I can’t have your cum everywhere, you understand?“

I nodded and blushed.

„Sorry.“

„So how are we going to handle this?“

„Maybe, uh, I could just be a little more careful“, I suggested.

„Hm, I was thinking diapers“, she said.

„What?“

„Diapers, honey“, she repeated, „So your cum doesn’t go everywhere when you jerk off.“

„You’re kidding, right? Like baby diapers?“

„No, sweetie, your size of course“, she said, „And obviously you won’t be wearing them 24/7 or anything. Just for masturbating. And afterwards you can go clean yourself up.“

I looked at her and she looked at me.

„No way“, I said but she didn’t seem to bother.

„Tomorrow morning when I‘m shopping groceries I‘ll go buy some for you, alright?“

She seemed serious about this.

„Or you could finally try fucking Haley“, she teased me, smiling, „No mess there either if you cum inside her.“

I sighed and looked at her.

„Can I please just eat right now?“, I asked genuinely. Mom shrugged.

„So you agree?“

„Yes, I‘ll wear diapers, alright“, I replied, annoyed.

„Wonderful“, she smiled and danced out of the kitchen, „I‘ll be in the bathroom, freshening up.“

„M-hm“, I replied and was happy to finish my warm mac and cheese in peace.
