Chapter 1

I had to share a room with my 15 year old sister Ellie. The room we shared was a couple of rooms down from our parents. I must have been horny because I thought it would be a fun idea to make a fake snapchat account and pretend to be a guy called Zack. I knew my sister just broke up with her boyfriend and was trying to get back on the horse. So maybe I could trick her into sending some topless pictures.

I was laying in my bed and she was in her own bed on the other side of the room. At 10:30pm I started a snapchat chat with her under this new Zach account. I asked where she was from and what she was interested in. She replied right away and seemed happy to talk to somebody. We continued to chat casually about nothing for a good while. Around 11pm I pushed for the chats to become more sexual.

After a few messages about how hot I thought she was, I sent a picture of my lower half wearing only boxers. It was a picture I had taken the previous day to send to some other girl. She replied with a picture of her wearing a bra and thong. I could see her clearly from my bed so the picture wasn’t new.

I knew she had a cute petite body, but I couldn’t remember the last time I had seen her in so little clothing. She always wears full pajamas to bed and changes in the bathroom if I’m already in the room. I was getting hard just looking at the skimpy picture she sent. I left my bed and went to the bathroom that was across the hall from our bedroom to continue replying to her.

I sat on the toilet and took a picture of my erect dick and sent it to her.

“Damn, that would be bigger than my exs.” She Snapchat text me.

I started to touch myself while reading her simple compliment.

“I’ll send you some pics from the bathroom later. I have to share the room with my brother and he’s hogging the bathroom.” She Snapchat text again.

“Family can be the worst sometimes.” text her.

“He’s not that bad.” She text back.

“Is he younger or older?” I asked, knowing the answer.

“He’s Two years older than me.” She replied.

I decided to leave the bathroom and walk back to my bed. She was still laying on her side looking at her phone.

“Do you have any fantasies of him?” I text.

She opened the message but didn’t reply. I thought I’d blown my cover or my question scared her away. Eventually, she did reply at 11:26pm.

“One time I had a dream that I was fucking my exboyfriend. But then my brother kicked my ex off me and then my brother fucked me himself” She text me.

She got up from her bed and made her way over to the bathroom. She didn’t acknowledge my existence as she walked past my bed. While inside the bathroom she sent a lovely nude picture, waist up, in the mirror. She had small tits with tiny nipples, but they looked perfect on her petite body.

“Has your brother ever seen you naked?” I text her.

“I think he’s seen my boobs once, when I came out of the bathroom.” She replied.

I had totally forgotten about that one time she walked in on me naked. Luckily I took a screenshot of the picture she sent me so I would have a memory to remind me. I tried to get her to flash over snapchat again, but I heard the bathroom door open. She walked back to her bed and got under the covers.

I got up off the bed and went into the bathroom again. I turned on the shower to let it heat up while I took off my clothes. I stepped inside and took more pictures of my hard cock and sent them to her.

She replied by sending me a video of her fingering her bald little slit with her pajama bottoms pulled down. The same Pajama bottoms she was wearing tonight, so there was a good chance the video was fresh.

In one of the dick pics I sent I made a mistake. There was a bottle of body wash and shampoo in the corner of the shower, which she must have recognised the bottles and how they were positioned.

I heard a knock on the door. In my horny excitement I forgot to lock the bathroom door and she walked in. I stood in the shower with my fully erect penis. She opened the glass door to the shower. I was shocked and completely exposed as I stood in front of my little sister.

“Are you Zach?” She said with an angry look on her face,

“Yes.” I said softly.

She lifted her pajama top and flashed her tiny tits at me.

“Well, Zach. Is this what you wanted?”

I was speechless.

“Take a picture ZACH, it will last longer” She said as she shook the held up top over her chest.

I raised my phone and took several pictures of her beautiful breasts.

“Hmpf” she grunted as she put her shirt back down and walked out of the bathroom

I looked over the pictures of my little sister’s tits and started to touch myself. I couldn’t get myself off because my mind was elsewhere. How mad is she? Will she tell our parents? Will she black mail me with the dick pics I sent her?

I got out of the shower and dried myself off. I put on a fresh shirt and boxers and left the bathroom. I saw her lying in bed turned away from me. I got into my own bed. At 12:14am.

Not much later she messaged me on the fake Zack Snapchat account.

“Could I sleep in your bed tonight, Zach?” She text.

“Yes.” I replied.
