Sheltered Siblings by Nt888

“Yeah, a, uh game would be awesome.” I said with a dry mouth

I could feel my penis growing inside my shorts, it was super uncomfortable and I had to awkwardly shift to try and adjust it into a better position. Ava seemed oblivious to my plight and looked at me intently. “Do you want to play hide and seek or something?”

“Uh, yeah sure.” I stammered while still staring at her face.

“Okay, I’ll hide! Count to fifty.” She said rising off of the couch and running out of the living room.

When I closed my eyes all I could see was Ava’s face, her body with her midriff exposed and her smooth legs. I had to reach into my shorts to adjust my penis, it had never felt like this. It felt almost painful, like it was filling up with pressure that desperately needed to be relieved somehow.

I realized that I hadn’t been counting at all and just guessed it had been long enough “Ready or not here I come!” I yelled out into the empty house. I had heard her clearly run up the stairs but I decided to take my time and hopefully take my mind off of Ava and make my penis calm down.

I walked over to the table where Ava had been looking through her textbook and grabbed the closed book. The top left corner had ‘Robertson’ written on it in black marker. She must have borrowed it from our neighbors or something I thought to myself. I opened up to where she had left her bookmark and let out an audible gasp when I saw what she had been looking at.

On the page was a diagram of a man and a woman showcasing what they looked like naked and the different reproductive parts that they had. I looked intently at the diagram of the naked woman. While it was clearly a educational drawing it still was the most amazing thing I had ever seen. I looked over the woman’s body intently wondering if this is what Ava would look like if she had no clothes on.

I looked over to the man and saw that his penis was much larger than mine was now. It had a large amount of hair at its base. I scanned through the text on the page until I got to the paragraph about the penis in an attempt to try and figure out what was up with mine. The textbook said that when sexually aroused a male’s penis would become erect and allow him to insert it into a woman’s vagina, allowing them to create a baby when the male reaches a climax. This was all brand new information to me and to be honest most of it went over my head. This was a text book mom and dad never would have let us look at, Ava must have snuck it from the Robertson’s.

At the very least this let me know that what was happening to me was normal and that my penis was actually having an erection because I was thinking about girls. My mind was all foggy as I went up the stairs to search for Ava. What was she thinking after seeing that page? Maybe she was also curious about what I looked like naked?

I searched through my room and went across the hall to the bathroom when those came up empty I went through the closets in hall way but still nothing. “Where are you Ava?” I muttered to myself. The only room I hadn’t looked at was our parents room at the end of the hall, but that was an off limits room for us. I took a deep breath and slowly turned the door knob and peered in. “Ava…are you in here? We aren’t allowed.”

There was no response so I slowly crept into the bedroom as if I was trying not to wake anyone up. I looked to my left and saw that my parents closet was slightly open. I walked over to it and opened it to find Ava hunched up in the corner.

“You found me!” She announced loudly.

“What are you doing in here!? We aren’t allowed Ava.” I said in a hushed voice.

“Cody, it’s okay, we are home alone, they don’t have to know.” She said in an excited manner.

“Yeah, I know.” I said reaching down to help Ava up to her feet.

She took my hand to stand up and then walked into the middle of the room before sitting down on our parents bed. “What are you doing? We should get out of here.” I said in a worried tone.

“This is where Mom and Dad um, do it.” Ava said ignoring my request. She was intently looking into my eyes which caused shivers to pulse down my spine.

“What?” I said as my face drained of all color, surely she wouldn’t actually be talking about this kind of stuff with me?

“Like, have sex you know?” Ava said once again looking straight into my eyes.

I shifted uncomfortably and was unable to formulate any words.

“You do know what sex is, right?” I tried my best to avoid her intense eye contact as she sat in my parents bed in front of me.

“Yeah I, um saw it in the textbook downstairs.” I stammered

“Abby let me borrow it, told me to look at that chapter. I can’t believe Mom and Dad hadn’t told us about it!” Ava said buzzing with excitement.

All that I could see right now was that drawing of a naked woman, I wanted to see Ava like that so bad.

“When I was reading it…and looking at those pictures.” She paused and was definitely looking over my body and comparing it to the drawings as I had done to her. “I, felt different. Like a good different but it was weird.”

She leaned forwards and whispered. “I felt it in my vagina, it became wet, but like a sticky kinda wet.”

The world was spinning all around me as she said that, she was experiencing the same things that I had been experiencing as both of our bodies had begun maturing.

The room was filled with silence as I didn’t know how to respond to what Ava was saying. Both of us were overwhelmed with a curiosity to learn and discover the things that our parents had refused to talk to us about.

“Yeah, uh this morning my, um penis got really hard and it also got really sticky at the end.” I confessed to Ava.

“Does your penis get hard often?” Ava asked looking at me with interest.

“Yeah,” I chuckle. “It is kind of annoying but it happens most mornings, today though it happened so much more.”

“The textbook says that it happens when a boy is excited, like in a sexual way. Was that because of the book?” She paused and looked down at her feet. “Or me?”

“Ava, you’re my sister, that’s weird. I couldn’t think of you in that way.” I said blatantly lying through my teeth.

Ava’s face filled with disappointment “Oh….never mind.” She muttered in a sad tone.

She rose from the bed and solemnly walked towards the door to leave our parents room. “Wait, Ava. I, uh lied. It happened to me because I was thinking about what you looked like naked.” I confessed to her as she grabbed the door.

Ava paused and looked back at me with a blushing face. “Really?”

“Yeah, I’m sorry if that’s gross or weird but whenever I think of you I feel different, like having butterflies in my stomach.”

Ava took a deep breath. “Same.” We both stood across from each other uncertain of what to do. “When I saw you this morning in your bed it felt like I was paralyzed, I couldn’t move. All I could think about today is what a boy looked like naked, what you looked like naked.”

The tension had flooded the room. Both of us were overrun by hormones and curiosity. In protecting us from learning about sexual things our parents had caused our curiosity to be pent up, until today when it was ready to explode.
