Stealing My Sister's Christmas Gifts

Everyone has their own holiday traditions. Mine started when I was about five years old and my sister was ten years old. Because she was so much older she would always get things that would seem so much cooler than what I would get, and I was a bit spoiled and jealous.

So that Christmas after Santa had dropped off presents, I would sneak downstairs and find one that was meant for my sister and sneak it up to my room. I’d then unwrap the present, claim it for myself, and hide the evidence.

Now seeing as I was a boy and she was a girl, the gift I stole was a Barbie doll. Obviously, I wouldn't play with that so I tossed it into my closet and went about like nothing happened. Of course that Christmas she got her first phone, so I knew I had to try again.

The following year I did the same thing and I got a pair of underwear intended for her, again tossed into the closet. On my seventh Christmas, I stole a bag of makeup, since she was twelve and had been really into it that year she had gotten a lot of it so she clearly wouldn’t miss this.

Again into the closet, hidden in the very back with the others. In the following five years, I managed to steal some knee-high socks, a dairy, a push-up bra, hair dye, and then a pair of very low-cut shorts that were a bit too big for me, not that I’d wear them.

On my thirteenth Christmas, I got a regular bra. It had driven me nuts. She was always opening nice presents like a laptop. So how was I so unlucky that I was always getting the most boring things? Well after that year she went off to college.

So she didn’t get presents delivered to our house. So four years later I had matured a bit and learned Santa wasn’t real.  I was now in college and I had plans to come back home to spend Christmas with my family.

My sister had recently graduated and was living with our parents again while she saved up to buy her first home. I don’t know why, but when I saw her I remembered the pile of stuff I stole from her and ran up to my old room to find it.

Luckily it was still hidden in the back under some clothes and boxes. So no one knew I had done that. I planned to get rid of them later before I headed back to college, but looking at them sort of put the idea in my head to do it again.

It would mostly be for fun, I really didn't want anything gifted for her, and maybe I’d give her everything and finally confess my secret Christmas tradition. So several nights later my parents set up the gifts they got for us while we were in our rooms working on stuff.

I waited until they went to sleep and I was about to leave my room when I heard my sister leave her room. I assumed she was going to the bathroom. I waited a few more minutes and when her door closed I went into action.

I tipped-toed down the stairs and made my way to the Christmas tree. I found the section of stuff intended for her and started looking at them. In the back there was a small flat present and something about it was calling to me.

I knew it was likely clothing, so it wouldn't be missed if I decided not to admit I stole it. I pick it up and sneak back up the stairs just in time. My sister had come back out again as soon as I closed my door.

I ran to my bed and sat on it and started to tear open the present. Of course, it was a tank top. It was quite big. It definitely wouldn't fit my sister. I take off my shirt and put it on. I was bigger than my peers, and it was still big on me.

It was quite comfortable though, so I ended up falling asleep in it. I get woken up by my dad the following morning telling me to get ready and come on down to open presents. I tell him I’ll be right there.

I get up take off the tanktop and go to hide it in the pile of other stuff, but the pile is gone. I turn around and look around my room for it and I immediately see several of the items around the room. I would have been confused about how they got there if I hadn't been shocked by what I saw.

My entire bedroom had changed overnight. There was now a vanity with a large mirror, some of the makeup I had stolen, and much more. It even had hari products including the box from the hair dye that was now empty.

Sprawled across the floor was a ton of female clothes, all in the exact spot where I had let my clothes off instead of cleaning them. From panties to bras everywhere. I looked inside my traveling bags that I hadn’t unpacked and inside were even more feminine clothes, including dresses.

There was no way I slept through my sister sneaking in her and doing all this… I gulped… If some mystic forced change my room, had it affected me? I looked down and was taken aback by the changes to my body.

I had massive breasts. I don’t mean big, I mean like they make watermelons look small. As soon as I looked at them I started to feel them. They were so heavy and slightly jiggling due to their size. My back started to ache a bit and I had to reposition myself.

That wasn’t the only thing that became very noticeable when I looked at myself. It was hard to see past my massive tits, but I had on those very lowcut shorts, and not only had my butt grown to fill them out, but my crotch also flattened to make sure they could be nice and tight against me.

I was about to scream when I heard another knock at my door. It was my sister and she told me to hurry up already. I didn’t know what to do, I couldn't go out there like this. What would I say to them? I stole my sister's Christmas presents and somehow turned into a girl.

I was sitting on my bed turning bright red when my sister got impatient and opened my door. I tried to tell her not to but it was too late. The door was open, she was standing in the doorway looking at me in my new extremely busty body with no top on.

She just stared at me and asked why it was taking me so long to put on a shirt. Now I was very confused. She didn’t see anything wrong with me? She said I looked the same as I usually do and then closed the door and once again told me to hurry up or she was taking my gifts.

I then heard her walk downstairs. I almost laughed, this had to be some sort of freaky dream. So I decided to try and play along. I put the tank top back on and look at myself in the mirror from my bed.

I can't believe I look like a woman, well actually I can’t believe I’m in the body of a woman. If this is real, how am I going to manage to carry around these massive breasts around twenty-four-seven? I gulp and get up, continuing to hope this is a dream.

I make my way downstairs where my parents and sister are visiting. None of them seemed slightly bothered by my new appearance, and I think I know why. Whatever changed me changed everything. All our family photos had changed to look like my new self.

There was even a set of photos of me from each Christmas opening the very gifts I had stolen. I sat awkwardly opening present after present of feminine clothing my parents got for me, all while trying not to seem ungrateful for the gift.

It wasn’t their fault everything changed and I became a woman, but it’s really hard to be grateful to receive a bra that fits these tits I didn’t want. After all the presents were gone my parents got up to go pour some wine in the kitchen.

That’s when my sister sat next to me and handed me one last present. She whispered in my ear that I was going to need it now that I was a woman. My heart dropped, she knew? I slowly open the present to reveal a large dildo.

I turn to her bright red and beg her to turn me back. She just smiles and says she has no idea what I was talking about. She laughed and let to go get wine with our parents. I sat there holding the dildo and regretting my actions… That’s something I will be doing for quite a long time.
