New Sister

Warning! I debated about where to post this story. The fact is I could post this in Transgender & Crossdressers. So this is a warning for those who don't want to read about the protagonist's new sister who used to be his brother. Nonetheless I wrote this story with incest in mind as my preferred taboo so I hope other's will enjoy the story as well in this regard. There will be a second part soon that will finish the story.

I do read every comment so feel free to criticize and give me ideas for the next part. Thanks for reading.

*****

When my brother came back from college he had changed. I was aware that there had been a change before he arrived. He had told us.

I had just turned 18. He was 23 then and none of us, not my father, not my mother, nor me, had seen him in over four years. He had left to college at 18 but after his first semester he got an opportunity to study abroad. He stayed abroad for the remaining of his education, in Spain.

My parents didn't like this but they couldn't do much about it since he was an adult. He talked to our parents on the phone while away but it wasn't until his final phone call before visiting us that he told them about his change.

He rang the bell and I answered the door. My brother had left over four years ago and now my sister had returned.

I was stunned. I wasn't sure how to react so I didn't react at all for a few seconds, I froze.

"Let me guess? You don't recognize me."

I shook my head and then we hugged. I asked boring questions about the trip absentmindedly. Then my parents came home from the store and hugged Brian and told her how happy they were to her. I remained mostly quiet for the rest of the day.

This was a big change for Brian but I knew he had transitioned. The change however was bigger than I had expected.

"Call me Bree." She told me the next morning at breakfast. I had been quiet the whole day she arrived because I was too concerned about what I was seeing.

First of all her voice was soft, which I didn't recognize on my brother. She was about my height, skinny, and pale white. She had a tattoo with a Chinese symbol on her left arm. She had a nice figure. There was the subtle curve of her breasts. She had boobs. These weren't gigantic but many girls would envy them. When she picked up her luggage her blouse had allowed me a peak at the new cleavage.

I noticed she wasn't wearing a bra. It was all natural flesh. She had a small waist and then came the kicker.

My brother had an average dude's body though I never paid any attention to it. The woman eating at my table didn't. The best way to describe it is my calling it a plump butt. She had been wearing leggings when she showed up and her raised and rounded butt drew my attention right away.

This morning she was wearing gray drawstring track shorts. They displayed her womanly sharp legs.

After breakfast I couldn't help myself but peek at the back. The shorts covered her butt but there was something too tempting about the way they stopped just under the butt cheeks. When she walked her ass cheeks stretched and shaped her shorts and I was stupidly caught staring down when she turned around.

Nothing was said but it bothered me to have been caught staring.

These thoughts were plaguing me. The days went by and I had to start avoiding her. I mean, we're family. Besides, I'm not gay and well, I don't know what's going on at the front end. I felt confusedly and aroused throughout my days.

Why was she so careless? At home she wore mostly small shorts and thin blouses. Her nipples were visible at times.

One day she came up from behind me, slapped my ass, and then put her arm around me. By this point I was talking to her like a normal human being. We laughed and then I put my arm around her lower back. We joked and then she turned away from me. I slapped her butt.

"Ouch!" She exclaimed. She twisted her upper body around, her head turning towards me while her butt remained in the same spot. I liked the expression of pretended pain in her face. She was pretty, I noticed. She placed her hand down over the butt cheek I had just slapped.

"That better not leave a mark!" And she raised her short's 'sleeve' enough for her ass cheek to come into view. It was a little red. "My skin is so pale see, now my cheek is red."

"It's gonna be alright. I'll even it out if you want me to." I blurted out.

She smiled. "I'll make you pay for this." And she walked away.

What did I say? This small interaction gave me a lot to think about. What had my intentions been by that comment? I went on worrying and trying to not think about the reactions my dick was having on a daily basis.

She helped Mom wash the dishes. I'd make excuses to go into the kitchen and glance at her ass as they spoke. She would shake her butt from side to side as she spoke. Was she doing that for me?

It was a daily routine they had. Washing dishes, mother and daughter. Then one day I came into the kitchen, they didn't turn around. Bree's left hand grabbed her hip and pulled her shorts up revealing some skin. She knew I was watching, I was sure. But then the real shock came over me when she laughed and her right hand moved to rest on Mom's hip and then drop down on Mom's ass.

As I was walking away I noticed a small squeeze she gave her.

Then one day she moved.

She found a job a week after arriving home and weeks later Bree moved to her own place. We visited her as a family a couple times and then I didn't see her for a little while. Mom visited her regularly by herself and often talked about her at home.

Her absence didn't help. I began to think about her more and more.

I wasn't the master of my brain.

So I paid her a visit.

"Hey!" She greeted me at the door.

"Hey." I replied shyly. "Am I interrupting anything?"

"That's just the TV. Come inside."

She was wearing pink sweatpants and a small blouse that ended on her belly button. The sweatpants were a bit baggy except for her butt area where the flesh inside stretched the pants to the shape of her butt.

"I'm not doing anything right now, just bored so I'm glad you came."

We walked towards the kitchen. "So what's it like to have a house."

"Oh, it was exciting just at first. What would you like to drink?"

"Oh, just water would be fine." She opened her fridge and pulled out a water bottle for me and a corona beer glass bottle for herself.

"You're a drinker now." I observed.

"I've been a drinker for a while. A lot has changed little brother." She smiled. "Anyways, it's really exciting having a new house at first but now it's kind of a pain."

"How so?"

"It's expensive for one. And then the fact is I don't really need all this space. I have three bedrooms and for what?"

"You never know who'll come visit."

"That's what I thought but mostly people don't stay overnight. This house is meant for more people."

"There you go, then I can be the one who stays here overnights."

"You are welcomed any time."

"What about work? Do you like it?"

"For the most part. There's a couple assholes at work but assholes are everywhere."

"Yea, they're everywhere. There's two here right now."

"That's true but some assholes are prettier than others."

I laughed. "Hah, and are there two pretty assholes here or is one prettier than the other?"

"Well, I like to brag sometimes and between you and me I have one very pretty butthole. I'd be surprised if you had something to compete."

I didn't know where this was going and I didn't know what more to say. I had been thinking about that butt for too long and the subject had to be changed or else...

"Are those 'assholes' at work gonna cause problems?"

"Problems for me? I don't think so. You should understand something about me. I've been around men all my life. I know how they are and how they act when they think no one is around. I know how horny and stupid they act, I have a dick too..." I blushed at hearing this. "But I'm a woman now so I have to experience the other side of it. The usual stuff women get. These asshole are not actually doing anything dramatic, it's just the offhand comments.

"'You look beautiful today Bree', the way they look at me. One of them is my boss and he's been calling me to his office for no good reason. He makes me serve him water every time I'm there and thinks I don't notice that I have to bend down and stick my ass out towards him while I do it. He ogles me."

"That's stuff I never have to deal with." I said.

"Yes. It's just the work environment. I don't want to get involved with anyone I work with. It usually ends badly."

"Why would you get involved with them? Don't you hate them?."

"It depends. One coworker I do like."

"So are you... um." I hesitated.

"Gay? I'm your sister John. You can ask me anything. And yes and no. I'm a woman, so no I'm not gay if I have relationships with a guy, and yes I'm gay if I have relationships with a girl."

"If?" I smiled.

"If. There's still boundaries. I've been away for a while so you'll get to know me better."

I continued my visits thus for the next few weeks. We got along well but after a while I had to admit it to myself. Lust was building up in me.

So one evening I decided to stay over at her place. She went off to shower while I watched TV on the living room. I stumbled upon a show we used to watch before. When she came out of the shower and into the living room she was wearing shorty shorts like the ones used for track and field. Black ones that allowed me to admire her smooth legs and a simple yellow blouse.

She saw what I was watching. "I love this show." Then proceeded by moving between the TV and me and dropping down.

First she knelt facing me. This caught my attention right away. The way she looked at me was strange. It wasn't a blank stare, it was calling for my attention and daring me with her eyes. So she turned around and dropped down on her belly.

So she lay down on the floor between the couch and the TV. It took me no time to forget about the TV. The shorts lifted up a bit to reveal the very bottom of her recently showered butt cheeks. There, flat on the floor, her butt stood out. It was beautiful and full. Plump. A bubble butt, whatever you want to call it.

She watched the TV with her elbows to the floor and her hands under her chin. Unconsciously it seemed, she began to rock her ass right and left.

I moved off the couch and sat on the floor.

"Sis."

"What's up?" She didn't turn towards me.

I grabbed her naked foot and began to move my hand up her calve and back to her foot again. I wasn't brave enough to say more yet but she broke the silence.

"I like how you do that with your hands. I've been walking all day little brother, please continue."

So I put my other hand to work too and began massaging her calves. Then I moved them a little higher, just eyeing my goal up ahead. Her legs were so tender and clean. She had great skin.

When I finally got up to above her knees I slowly touched. I was still unsure of how far I would go but I also didn't want to do anything stupid. But then I felt her left foot.

Her left foot moved up and found my crotch. I hadn't even noticed my erection until the bottom of her foot found it.

She moved her foot up and down against my cock. Since I was wearing shorts the barrier between our skins was so thin I could feel the shape of her foot. This sensation stopped me for half a minute.

"Please continue John. My legs are so sore." This snapped me back to the task at hand. I could not ignore the foot lightly slapping me cock and it increased all other sensations.

She had nice legs. Shapely womanly legs. Her thighs were so soft, I moved faster. I couldn't help myself.

I massaged her legs for just a minute before I moved up. I moved my crotch past her foot which meant not more footsie cock slapping. But that was the price I was willing to pay because now my hands took hold of the thigh area just underneath her butt cheeks. One hand stayed there and then my right hand ascended.

Lightly I placed my hand on her butt cheek. She didn't react so I pressed more and more firmly.

Then I dragged my left hand up her thigh to her other butt cheek. Without realizing how fast things had moved, I found myself playing with her ass, pressing my hands, pinching her, feeling her. I was so worked up then she raised her butt up by lifting her hips off the floor.

I was breathing harder when I grabbed her hips and moved up against. She has such beautiful ass and my cock was big inside my shorts. I grabbed the elastic waist of my shorts and pulled them down. I was acting on instinct, with no consciousness, when my erect cock popped out.

The fabric of her shorts was also very thin.

I just needed to move a little closer to get my dick to rest on her ass. My cock sat in between her ass cheeks. I let it be for a few seconds.

Then I bounced it lightly up and down enjoying every time my cock touched her. The longer this went the hornier I got. I brushed my cock from left to right all over her ass.

I backed up a little and moved the tip of my cock against her skin just under the shorts. I saw the wetness of my head transferred to her skin. I moved it up so it found its way into the shorts. The shorts were so tight that it was difficult to do so. On one side I felt the shorts against my cock which wasn't the most pleasant. On the other side however it was heaven.

My cock was hard pressed against her butt so I started moving forward and backwards. She broke the silence.

"You're not so little any more, my little brother." I continued moving. "I think it may be time to prove it to you how pretty my butthole is." My cock was so hard at her words. After a minute or so she continued. "I'm so hard already."

I snapped. I still felt very confused. I became more aware of how much I had gone. I was so turned on and yet...

I stood up abruptly.

"I... I should go."

"What?"

I pulled up my shorts and picked up my shoes.

"I need to go.." I said.

"Aren't you gonna finish what you started?" She shook her butt at me.

"I.. I'm sorry I have to go?"

"You've been looking at it from day one brother."

We made eye contact. I didn't know where the strength to turn away came from but I did. I left the house with a raging boner in my shorts.

I tried to avoid thinking about what had happened but I couldn't. I didn't sleep much that night. At 10:30 when I arrived home Mom was in the living room hanging up the phone. She wasn't surprised to see me.

"Hey honey, I thought you were staying at your sister's, did something happened?"

Her eyes moved up and down on me.

"No, I, I, changed my mind. I have some stuff to do tomorrow morning." I quickly hurried away doing my best to hide.

"Okay, goodnight honey." She yelled behind me. Damn it, she saw it. My shorts were not good at hiding my boner.

I had to calm down. Fuck, fuck, fuck, I was so horny.

To my surprised the door to my room opened. It was Mom. I was sitting at the edge of my bed.

"Everything alright?"

"Yes, Mom." She entered the room.

"Should I call your sister?" I must be losing my mind I thought. Mom was wearing a light pink flowy nightgown that was see through. Underneath she wore lace black panties and a black brassiere.

Somehow my first thought was Mom's thickness. She wasn't fat, you would think of her as skinny but maybe that's just because she is a bit short at 5'3". Yet I couldn't help but notice how her panties pressed down against her skin and then I hadn't noticed before that Mom had big breasts.

"No, why would you? I just had to do something tomorrow." She sat down next me.

"Baby, you know you can tell me anything that is bothering you right?" She grabbed the back of my head and pulled me down against her chest. I had many thoughts going through my head with my eyes wide open and so close to her breasts.

Yet even so I wasn't prepared for what came next.

In the middle of my answer, "Yes Mom I know..." Her hand landed on my cock. "There's... nothing wrong..." She patted my member over my shorts.

"Okay I'm glad you know you can trust me. I'll let you go to bed now." She let go of me and stood up, was about to walk away but stopped.

She picked up some piece of clothing from the floor, what piece of clothing? I do not know.

I do not know because her nightgown was magnificently shorter from the back, when she bent down I was flashed by her chubby ass stretching her black panties only a couple of inches away from my face.

She stood back up, murmured something I didn't hear, and left my room.

I rolled around in bed for a while. It was a strange night in which I had to come to some conclusion. Of course I masturbated but it didn't help in my confusion, my mind was haunted.

Main conclusion about my sister: I wanted to fuck her. Mostly because that ass was incredible. This thought carried over to the rest of her body. I couldn't wait to get my hands on those perky tits. I kept thinking... She had a beautiful face, fuckable I might add. Fine features all arounds, her make-up wasn't being over used but it highlighted the sculpted face. I wanted to do things to that mouth I could not deny this.

Which brought me to the second conclusion, or question. She had a cock. I have never had a desire for men, thus her cock was in the very least an intimidating concept.

What was I supposed to do with it? I certainly didn't want to be fucked by it. Tonight I had lost my mind in such a wonderful way. My cock had rubbed against her skin. It was scary to think about how far I could go. It's all confusing. Then what the fuck had happened with Mom? I pushed thought thoughts out of my head.

I only slept that night because I gave up at some point and I masturbated again to the dirty thoughts I was having.

///////////////////////////////////////////////////////////////////////////////////////////////////////////

I didn't get much rest. Not only did I not sleep much but the next morning was a Saturday and it allowed a certain someone to visit.

Bree was having breakfast in the kitchen by the time I woke up. "Hey Bree." I didn't make eye contact, I couldn't. Yet she moved around the kitchen after she had finished her breakfast and my eyes drifted towards her. She had a plain white t-shirt and a velvet red skirt.

The skirt was short and as she moved it swung from side to side threatening to display more and more flesh. And then she did.

While I ate she talked to Mom who was washing some dishes. They spoke and I looked up. Her hands came down to the small of her back and then it went lower and lower, reaching the lower edge of her skirt.

For me and for me only, she knew what she was doing. She lifted the skirt slowly revealing the absence of another piece of clothing underneath.

Her round beautiful butt cheeks. Her hand yet again was lowered keeping the skirt up and away. She grabbed the bottom of her ass cheek and squeezed. That meat could be mine. I thought.

I couldn't help but grow a boner. Yes, I could have walked away but can anybody blame me for not doing so? When Mom walk away Bree slapped her ass. Mom didn't react and simply walked out of the kitchen. I didn't hear where she was going, I didn't hear anything that had been said between the two. Bree came to sit next to me.

"How you been since ...?" She asked.

"I'm okay. You?"

"Wonderful." She placed her hand on my leg and began to move up and down just barely touching my dick. I stood up once my dick began to move on its own.

I walked to the sink and began washing my plate. She didn't hesitate. "Here, a woman should do the dishes." She grabbed the dishes from my hands and suddenly she had moved against my body.

I gave way until she stood in front of me. My hands found her hips and I pulled her butt closer. My cock wasn't fully erect for just a moment. Then it was big, it was hard, and I felt her cheeks against it. She pushed back, I pushed forward.
