A little too curious

Just another day in my room masturbating to my porno magazines for the 3rd time today. I’m 16 what would you expect. I live with my mom, dad and my sister. We never saw much of mom and dad because of there jobs so I was always the man of the house when it comes to watching my younger sister. It was just like any other day. I was masturbating again and as I ejaculated I heard a noise outside my door and I noticed my door was cracked. My mom and dad weren’t home and I assumed my sister was asleep. Maybe it was nothing so I stowed my magazine under my bed and went to sleep.

I come home the next day and go to get one of my magazines and it was not placed in the spot I originally placed it. I was afraid my parents found it while cleaning my room. Come to think of it they weren’t going to be home for another 2 days so it couldn’t have been them. Then I remember back to the noise I heard last night. Could that have been my sister looking at me touching myself? I couldn’t believe it so I just left it at that. My little sister looking at my cock and me cumming everywhere. I didn’t want that be true. The what ifs kept nagging at the back of my head. Later that night I decided to crack my door just a wee bit more than last time so I could see if my sister was actually spying on me. It was late and I got bored so I decided to play with myself, forgetting that I have left my door cracked to catch my sister peeping. As I was stroking my penis I glanced over to the door and I could see an eye. This was my sisters eye. I couldn’t believe it but for the life of me I couldn’t stop masturbating. Even with my little sister eyes locked on to my cock it made me want to finish. I got even harder and my pre cum was flowing like crazy. Was the thought of my sister watching me turning me on? No, I just have to finish and go to bed. I finished with the biggest load I’ve ever made. It came out in thick white lines on my chest. It would normally lazily drip out but the shear force that my cum shot out was just proof to what’s to come.

The next day before mom n dad got home I went to my sisters room and I confronted her. This was going to be so weird and I almost didn’t do it but I had to.

“Listen I saw you looking through my door last night. I’m sorry you saw that and don’t tell mom n dad”

“I’m sorry big brother I didn’t mean to.”

“Its ok I forgive you but what made you want to do that to your big brother?”

“Mom told me to make your bed one day and I might have found one of your magazines and I might have taken it to my room to look at.”

“Don’t take things that don’t belong to you. I can’t believe you were looking at my dirty magazines.”

“I’m sorry again and when I was looking at all those penises I couldn’t help myself but to go and look at yours.”

“Well I’m pretty sure you got a pretty good look at my penis last night now didn’t you. Not cool little sister.”

“Yes I did. I just wanted to see a penis like in your magazine. I kinda like them. Umm could you tell me what the girls in the magazine were doing?”

“I get that your curious but for your brother to educate you on sex is not my job”.

“Could you tell me about it? I mean mom and dad are never home and you seem like you know everything there is to know.”

“Omg this is so awkward but I feel like I started this so I will answer any questions you have.”

I started showing her in the magazine that this was a blowjob. This is the shaft of the penis and at the top in the head. These are the testicles that hold sperm.

“The stuff that comes out of your penis?”

“Yes”

Her eyes were wide open as she was super inventive on asking questions and absorbing all this sexual knowledge.

“Um big brother can I see your penis again? It’ll help me if I see it in person.”

I had mixed feeling on this but I reluctantly agreed to educate her on male anatomy. I stood up and pulled down my pants down to reveal my not yet fully developed penis. I lifted my flaccid penis to show my testicles. At this point I was starting to feel uneasy and starting to get aroused. This is the first time a girl has seen my penis. I know nothing was going to go further than this but I started feeling strange. I could see her taking all the mental photos. Remembering the curvature and contours of my genitalia. My penis pulsed as blood was slowly filling it. I couldn’t stop it so I asked her if she had anymore questions before I pulled up my pants.

“Does touching it feel good? Is that why the white stuff comes out?”

“Yes it feels good to touch it.”

“Its growing like in the magazine. Does that mean it feels good?”

I couldn’t believe I was going this far with this as my boner was dangling in front of my sisters face. My hormones were going crazy as my dick continued to fill with blood. I looked down and noticed pre cum was starting to ooze out the tip. This was a different feeling all in itself. Before I could save myself she grabbed my penis. The shockwave of pleasure then ran through my cock was astronomical.

“I wanna do what they they do in the magazine.”

I couldn’t pull away. My new perversion for my little sister didn’t want me to pull away. The corrupt mindset to walk my sister through sexual acts on his brother was too great.

“Ok you’re just going to keep pulling up and down just like that.”

“This is fun big brother. When does the white stuff come out?”

“It’ll come out soon little sister”

I couldn’t believe it. My sister was jerking me off. I knew I would regret this in the morning but was looking forward to more and more with every stroke she gave. As she looked up at me with her smiling face I knew she was loving it as was I.

“Hey brother can we do this?” as she pointed to a girl giving a blowjob on the magazine. I nodded my head yes. She slowly wrapped her soft little lips around my throbbing cock I said “suck as if it was popsicle”. I felt this empowering embrace over my sister. I couldn’t believe but she got the hang of it. The slurping and sucking of my cock was music to my ears and with my parents gone I had no worries. She was getting into it and having fun.

“I like the taste of your semen brother. Its so hot and sticky in my mouth.”

“Try putting all of it in your mouth.”

I could feel the back of her throat on the head of my cock. She sucked harder, faster and went deeper. I was coming up on my climax as I stood over her as she was making my cock disappear with her mouth. I reached my limit as I shot my hot semen in the back of her throat slightly gagging her. My pulsating cock that just kept spewing semen into her mouth as she kept sucking. Not knowing when to stop as she was making my leg twitch with every throb of my cock dispensing cum with every head nod she made. She looked up at the good job she did with her innocent mouth full of my cum.

“That was fun wasn’t it?”

“You gave me a lot of semen big brother. I almost couldn’t swallow it all” giggling. “Can we do that again?”

I was completely drained. Tomorrow I promise.
