Three months ago, I became a new half-brother at the age of eighteen.

Even though I knew this could be considered normal, it still felt strange being so much older than my new sister.

My dad was 53, and two years ago, he married a 28-year-old woman. Cutting to the chase, she had her child three months ago, at the tender age of 30.

It was strange when I first went over to see them with a baby, but over the months, I got used to it.

One day, I walked up to my Dad’s place, took out my key, and unlocked the door, letting myself in.

“Hello!” I screamed as I walked in.

“Hey Steve,” my “stepmom” Carley called. “In the living room.”

Walking into the living room, I was slightly startled as she was breastfeeding Lindsey on the couch.

I wasn’t offended or anything, I just didn’t expect it. She must have noticed that.

“I hope you’re not offended by this,” Carley said, smiling at me.

“Was just finishing giving her a snack before I put her down for bed.”

“Oh no, not at all,” I replied quickly.

“Good,” she replied with a soft smile. “I’ll be right. Going to put her down and let your Dad watch her for a while. Though he’s taking a quick nap, he had a hard day at work, I guess.”

“Figures,” I said with a bit of a knowing look.

“Yep, that’s him. Always the party crasher,” Carley said and got up from the couch. In doing so, I got a view of one of her breasts as she hadn’t put that side of her spaghetti strap top back on yet.

She wasn’t wearing a bra, and while I had noticed it before, her breasts really had grown quite a bit since her pregnancy. Probably has a lot to do with the milk stored in them now. She used to probably be something like a B cup, I never looked that hard, really; she was my stepmother after all. But now she must be a large C cup, I would think.

When she came back, I was sitting on the couch with a bottle of water. Walking back in, I looked a little more closely at her breasts and entire body; they really had grown a considerable amount.

Carley was very good-looking at 30 years old, especially considering that she’d given birth three months ago. She had pretty pale skin but thick black curly hair that flowed down to her shoulders. Her eyes were blue, and her lips were a bit wide with great fullness. She was pretty much back in good shape, losing most of that extra pregnancy weight, which, in just three months, was pretty amazing. Carley was pretty tall, about 5’8″, and what she wore only helped make her look better. Not that she really needed it.

Since it was the middle of summer, it made sense that she had on the black spaghetti strap top, which she had put back into place, but still no bra. She was then wearing light-colored jean shorts that probably went to about mid-thigh, showing off her legs nicely with a pair of easy slip-on sandals.

“Would you like anything else to drink besides water?” Carley asked as she noticed my bottle of water.

“No, water is just fine,” I replied with a soft smile.

“Oh, being healthy tonight, huh?” she teased lightly.

“Hey! I am most of the time,” I shot back playfully.

“Well,” she replied, looking at me. “With a physique like that, you must.”

“Water does help,” I replied mid-laugh and with a smile. “Thanks.”

Carley then walked over and sat right next to me on the couch as she turned on the TV, probably only about four inches separating the outside of our legs. She turned the volume down low enough so we could still hear each other talking.

“So did you have a decent day?” Carley asked, turning her head to look at me.

“Yeah, it wasn’t too bad,” I replied with a smile.

There was a moment after I replied that we both looked into each other’s eyes a second longer than normal before we both turned our heads to look back at the TV.

“Ahhh crap,” Carley sighed as she stretched her legs out in front of her, stretching her muscles.

“I forgot the breast pump in the kitchen, and I am so full of milk right now. Lindsey didn’t want much earlier.”

She gently held her breasts underneath them on the bottom as she referred to how full they were.

It was then that I noticed her nipples were really hard and pushing outward underneath her top, and there the region was wet from escaping milk.

I didn’t think they were like that when she walked in, so it must have happened sitting here.

It felt kind of wrong marveling at her breasts like that, but I can’t say I didn’t like it either.

“I can go get it for you,” I replied, looking back at her eyes.

“Oh no, don’t worry about Steve,” she replied with a soft smile. “I can do it later.”

“You sure?”

“Yeah,” she replied with a smile.

As she said that she moved herself right next to me, the sides of our bodies touching, and she laid her head down on my shoulder, “I’m sure.”

I wrapped my arm around her, letting my hand rest on her shoulder as I held her gently.

Her hair smelled so good, a fruity smell, maybe mango or something like that. She must’ve taken a shower a little bit before I got here.

“I hope she turns out to be as nice and caring as you, Steve,” Carley said softly with her head still on my shoulder and looking forward.

“I’m sure she will, and thank you for the compliment.”

With that, she moved her head, looked up at me with her pretty blue eyes, and said,

“Of course, Steve. You fully deserve it. You’re a wonderful stepson.”

I smiled back as she said that and matched her smile. We held the gaze for a few moments, looking into each other’s eyes, perhaps a couple of seconds too long this time. Breaking the gaze, she laid her head back on my shoulder. Looking down, I noticed her nipples were still hard, maybe even harder now, and the wet patch of milk was slowly growing. Was I turning her on, or was it the wet milk that caused her nipples to harden? I think I was getting turned on, I mean. Even though it was wrong, I knew that I liked the thought of it.

“This may sound kind of strange, but I was wondering...” I started to ask, looking down at her.

“ ... Do you ever ... taste yourself? I’m just curious. I would think mothers would.”

Propping her head up a bit, she looked back at me with a huge grin and asked, “You mean my milk, right?”

“Uhhmm...” I started to reply as I let it sink in what she said, and what I had asked her, realizing that what I’d asked could have meant something very different ... and I quickly said,

“Yes, your milk.”

“I have actually, yes ... It’s kind of sweet tasting with a bit of saltiness to it,” she said, giggling a little bit as she smiled back at me, obviously getting what I was realizing.

“Why? Did you wonder what it tasted like?” she continued.

“Just curious, really,” I replied somewhat innocently. “Though I guess now that I think about it, yeah, I did.”

“Would you like to try some? It is safe for grown people, too!” she said playfully.

“Uhmmm, seriously ... I ... Noooo, I couldn’t do that, Dad...”

“Ahhh Steve, don’t be such a wuss ... Come, I can see it on your face, and...” she said and looked down at my growing crotch.”

“Ok, fine ... I ... I guess so,” I said somewhat hesitantly.

Not quite what I had in mind, but this seemed o.k.

“I’ll go get a glass.”

As I moved to get up, she stopped me, placed a hand on my chest, and softly pushed me back down onto the couch.

“No need,” she said with a smile, looking me in the eyes. “It is best if you try it from the source.”

“Carley ... I’m not sure that’s a great idea ... I mean, I know we’re not related, but you are my step-mom ... married to my Dad.”

“Oh, it’s fine,” she said reassuringly. “One little suck isn’t going to hurt anyone and no one will ever know but us.”

With that, she pushed both straps of her top down her arms and her top down, over and off of her breasts. Exposing them to me. Her large, pale-skinned, luscious-looking breasts were gorgeous.

Her aureoles were really dark pink, big, and swollen, with her nipples hard and pushing straight out. Her breasts hung down a bit, and she pushed them out by pushing her chest forward as she looked at me.

“Wow, they’re gorgeous,” I whispered under my breath, realizing a moment later she probably heard me.

“Thanks, Steve,” she replied with a smile, looking at me and gently cupping her breasts at the bottom of them.

“Take your pick as to which one you want your sample from. Just be careful, they’re even extra sensitive right now.”

I smiled back at her, looking into her blue eyes before slowly lowering my head. I moved my mouth toward the one closest to me, her left one. As my mouth neared her nipple, I slowly stuck out my tongue and gently flicked the tip of her nipple. She drew in a short quick gasp as I did and I knew, even if it was wrong, that she probably wouldn’t mind if I had more than one quick suck.

As my mouth reached her nipple, I grasped it with my lips. Gently flicking it with my tongue inside my mouth, I began to softly suck on her hard nipple. Feeling milk seep out of her nipple and into my mouth I sucked a little bit harder as then her milk squirted into my mouth. It did taste somewhat sweet with a hint of saltiness. It wasn’t too bad as I swallowed it and sucked harder, getting more of her milk into my mouth.

After that larger suck, I removed my mouth and ran my tongue from her nipple across her other breast to her other nipple. Grasping that one in my lips just as I had the other, I began sucking on it taking her milk into my mouth. Moving my hand up I very gently pinched her other nipple as I sucked.

“Ohhh,” Carley sucked in a sharp gasp. “Oh Steve, I haven’t been touched like this in months.

This isn’t right, but don’t stop now.”

Hearing her say that only made me suck harder, taking more of her sweet warm milk into my mouth. After I had a little more of her milk, I removed my lips from her nipple and looked up at her, smiling. She returned the smile and looked at me with her blue eyes, which said that she clearly wanted more.

Moving my head up to be level with hers, I took a chance, leaned in, and kissed her gently on her soft lips. She didn’t back away, instead, she kissed me back, gently at first, but soon we were kissing passionately. She had wrapped her arms around me and pressed her breasts into my chest. I had one arm around her while my other hand was pinching one of her hard nipples.

In the middle of our embrace, she abruptly stopped and pulled away. Looking back at me, she said suddenly,

“We can’t. This is wrong. What are we thinking? But especially not right here and now, he’s only taking a nap. He could wake at any time.”

“Yeah...” I sighed softly as I leaned in and gave her a quick kiss. “I guess you’re right.”

“No more of that either, except this last one,” she said with a sly smile as she gave me a hard, deep kiss before pulling away.

Carley then cupped her breasts in her hands, gently kneading them outward, squirting her milk out of her nipples at me, particularly my face. I smiled at her as she did it a few times before putting her top correctly back on.

“I’m so glad you liked that,” she said, gently wiping the milk off my face. “I don’t know if we can ever continue this as it is wrong, but deep inside me, I definitely want to.”

“I know,” I smiled back at her.

“Good, I am glad we understand each other,” she replied.

“I’m going to get a late dinner ready for the three of us.”

With that, she got up off the couch and left the living room. I couldn’t believe what had just happened. Was this not some sort of dream? No, I guess it wasn’t. I had just sucked milk out of my stepmom’s nipples and we had both enjoyed it immensely.

The rest of the evening went by, we had our dinner, and talked about random things before it was time to wrap things up.

I said my good nights and went to my childhood room at my old home, now my Dad’s and Carley’s, sorry Stepmom’s.

It was up on the third story of the house. It was somewhat of a loft as it was the only thing up here; the staircase came directly into the room after opening the door.

Getting into bed, I undressed and went to bed, naked, like I normally do. It was warm enough, and this was kind of like home to me, so I figured it would be right. After a little while of dozing, I fell right asleep.

I wasn’t sure if I was going to hear the baby during the night, as they were all the way down on the first floor. But sure enough, I did. At about 2 am, I heard her start crying.
