(Writers note: This one turned out to be much longer than I was expecting. Easily the longest I’ve written since I started this. I recommend getting a sandwich or something, this may take a while.)
It started innocently enough. I was sitting in my room staring into my computer when my little sister walked in. “Hey, um. Can I ask you for help with something?”
I pushed away from my desk and turned around. “Sure, anything. What’s up?” She walked into my room, obviously nervous. She looked down at the floor, desperate to avoid eye contact with me. She shuffled over to my bed, and sat down.
"So I was talking to Sarah today…" Her best friend, and by all accounts at school, a bit of a slut. "She was talking about what she does with boys. And…" She took a deep breath and closed her eyes, then just came out and said it. "She says she can deepthroat a guys cock…" I was stunned for a moment, not exactly sure what to say.
"Oh, uh. Well, yeah. Some girls can do that I guess." I was a little uncomfortable. In part because I’d never heard my little sister say "cock" before, and because my cock was starting to fill up. "So what does that have to do with you?" I asked, trying my best to move things along. What she said next I was NOT expecting.
"I want to be able to do that too. And I…I wanted to know if you would show me how." Her face went red and she kept her eyes locked on the floor. My face was starting to blush as well, and my cock was starting to grow rigid in my jeans. I shifted trying to hide it.
"You what?! Are you serious?"
"Yes! I’m serious!" She snapped back, clearly embarrassed. "I trust you, and I love you. You’re my big brother and you’ve always been there for me. I just thought you could help." All I could do was stare at her, speechless. "Ok, fine. This was a bad idea, sorry…" She stood up, and walked around the bed, heading for the door.
The time it took her to walk towards my bedroom door seemed to go in slow motion. Thoughts were racing through my head. I was waging a battle in my mind. My brain telling me that this is wrong, and I couldn’t agree to this. My cock, with a mind of its own, told me otherwise. Each step she took seemed to take minutes as the two sides fought for control.
In the end, my cock won.
"Wait!" I shouted, causing her to turn around surprised. "I’ll do it. I’ll show you." Her eyes went wide, and she finally looked me in the eyes.
"Really? You will?" Her voice was shaking nervously.
"You’re going to try to learn how to do this at some point. I would rather it be with me than one of those dirt bags you hang out with." That was only half the truth.
She smiled wide, and ran towards me. She jumped into my arms, hugging me tightly. “Thank you! Thank you so much, I knew I could trust you with this!” I held her in my arms tightly, and I could feel my hard shaft straining against my jeans, pressing into her leg. She felt it too, and when I placed her back on the ground she looked up at me grinning, and gently ran her fingers along my bulge. I tried to say something, but I just mumbled something incoherently.
"Ok, let’s start now." She said as she slowly sank to her knees. She reached up, and grasped the zipper of my jeans, pulling them down. She reached her small hand in, grasping my stiff member. The feeling of her hand around me was unbelievable, and she took a moment to get used to my hot prick in her grip. She gave it a couple small pumps, evoking a subtle groan out of my lungs. She giggled, then pulled my cock out of my pants.
She looked up at me, gently stroking me. It took me longer than it should have to realize she was waiting for me to show her what to do. “Oh, uh. Ok, well slide it into your mouth. Try to relax your throat. Focus and try to resist your gag reflex.” She nodded, then brought her eyes to my cock.
She moved her head forward, her mouth open. I felt her lips reach the tip of my cock, then slide along my shaft. I felt shocks shoot through my spine as my youngest sister pushed her head further. I felt my cock press against the back of her throat, and she looked up at me. She reached for my hand, then placed it on the back of her head. She wanted me to help push her deeper.
"You tap my leg when you need me to let go." I said to her, and she nodded. I put pressure on the back of her head, my cock pushing past and millimeter by millimeter sliding down her throat. I felt her throat gag and pulse around me, but she kept going, taking more of me down her throat. Then suddenly her eyes went wide, and she quickly tapped me on the leg. I instantly pulled my cock out of her throat, and held her in my arms as she coughed and gagged. I rubbed her back as she recovered, tears rolling down her eyes as she looked up at me.
"You did really well for your first time." She smiled, still coughing softly.
"Sarah bought me a toy. I’ve… *cough* *cough* I’ve been practicing for a couple weeks. But…you’re bigger than the toy." I took that as a compliment, and leaned in to kiss her. She seemed surprised, but receptive as she slid her tongue in my mouth.
After a passionate few moments, I broke the kiss and looked at her. “Um, do you want to try again?” I expected her to say no, but she smiled, and nodded her head. I stood back up, and she brought her lips back to my cock.
She pushed her head down on my cock again, my hand giving her a little extra support. She took me deeper and deeper. I felt her lips reaching forward, almost as if to grab my cock and pull it deeper down. She reached the point she gave out on our first attempt, then past it. Maintaining her control, she took more of me down her tight hot throat.
I groaned, and I could feel my balls tightening. Having my sister’s throat wrapped around my cock was too much for me. I started to feel that familiar tingling, and I knew I was going to cum if she didn’t get off my cock. “Sis, this is going to make me cum…” She didn’t stop, she just took me further and further until finally, my entire shaft was buried in her throat.
She held for a second, controlling her gag reflex, then slowly released me, proudly sliding my cock out of her mouth. Her lips dragging along my prick finally pushed me over the edge, and I groaned loudly. She knew what was happening, and sealed her lips around the head as my balled emptied in her mouth. She kept the seal tight, not a drop spilled as I shot more and more. When I finally stopped shooting, she looked up at me and let go of my cock. I could see a pool of my cum in her mouth, before she closed her lips and with one enormous gulp drank it all down.
"Jesus….that was…." My thought was disrupted by a light headed feeling. I fell backwards into my chair, my cock still sticking out of my pants. My sister stood up, and wiped the tears off of her face, and looked at me lovingly.
"Thank you so much. You’re the best brother a girl could ever have." Then she leaned down, and wrapped her arms around my neck, kissing my cheek. "I love you." she barely choked out. I just looked back at her and smiled.
"I love you too." She stood back up straight, smiling widely, and turned to leave the room. And just as she was about to leave, she turned her head and looked at me.
"Would it be ok if we practiced more tomorrow?"
That’s one lucky sister with such an understanding brother. ;)
