Read the erotic story. Teaching my younger brother how to have his first sexual experience.

I first met my half-brother when my parents got married. He was about thirteen years old then, and I was in high school, about to go to university. Because he'd never had an older sister before, many things felt unfamiliar to him. I didn't know how to approach him or get closer to him, especially since he was quite handsome – you could tell he was good-looking even as a child.

Of course, the transition from childhood to adolescence involves a major issue: sexual urges or sexual desire. I'd been through it myself, but I didn't know if my brother had. Then, one day, I came home early and my parents weren't there. I heard him moaning from the slightly ajar door. When I peeked in, I saw him watching porn on his phone and masturbating, but with a homemade sex toy in his hand – the kind people share online.

I immediately opened the door and showed myself. He was startled and grabbed the blanket to cover himself, looking like he was about to cry, afraid I'd tell our parents. But I closed the door and sat beside him, telling him there was no need to hide anything from each other; it was normal human behavior. I tried to calm him down. He finally calmed down and asked if I'd ever seen a real vagina. He shook his head, saying he'd only seen them in porn.

"Okay, then look... I'll show you the real thing."

To convince him, I took off all my clothes so he could see my big breasts and my big vagina. His eyes widened immediately, and he sat still. I then removed the blanket and pulled out the fake vagina as well. Surprisingly, he was so young, and his voice hadn't even broken yet, but he had a surprisingly large penis. I told him I wanted to get closer to him, and today I wanted to give him some experience. I reached out and started masturbating him. His head was already exposed, so I pulled his penis all the way down. I figured it was at least 5x5 inches, which is pretty big for his age.



I slowly masturbated him until he started moaning and put down his phone. I immediately bent down and gave him a blowjob. He groaned and said I didn't have to, but it was too late; I was already aroused. At first, I thought it would be small, but it was surprisingly big and good. His dick smelled amazing and felt incredibly good. I sucked and licked his dick for a while until I couldn't hold back anymore. I looked up and asked him if he wanted to try real sex.

He nodded immediately, without hesitation. I knew that since he watched a lot of porn, he probably wanted to try the real thing. So, I slowly lay down, spread my legs, and showed him my pussy. I told him to come closer. He smiled and moved closer. As soon as he inserted his dick into my pussy, I closed my eyes and moaned…

His dick slowly pushed deeper and deeper, giving me intense pleasure. Being a horny young man, he started thrusting rapidly, fucking me until our bodies slammed together loudly. My younger brother tilted his head back and moaned incessantly, and the more I moaned along, the harder he seemed to thrust.

"Oh my god...sister, it's so tight... Mmm...it feels even better than masturbating."

"Ah, ah, ah, ah...then thrust harder! Ah, ah!"

I clenched my vagina to grip his penis, making him contort even more, before I told him to stop and took over, riding him instead. My brother lay down, his penis already erect, waiting for me. Once I sat down, I showed off my skills, riding him, gyrating my hips, grinding against him with all my might, leaving him speechless. He caressed my body for a while before saying he couldn't hold back anymore, that he was about to cum.

"Oh my god...sister, I can't take it anymore! I'm about to cum! It feels so good! Ah, ah, ah...oh my god!"

"Come on, cum inside my pussy! Ah, ah, ah...oh my god...it feels so good!" "Ah... I love your dick so much!"

*Thump, thump, thump, thump*

Hearing that, I got even more excited. I leaned in and continuously rode his dick until his face contorted with pleasure he'd never experienced with a fake pussy. His body twitched and tensed, he squeezed my breasts tightly and released his cum into my pussy, cumming inside just as I wanted, causing him to completely surrender to his ecstasy.

I sat there until he started to soften, then I got up and lay down beside him, letting him play with my breasts. He said I was very kind for teaching him, and that from someone he wasn't very close to, he started to be affectionate and asked me to have sex with him more often. Of course, I'm single and horny, so it made me agree to let him have sex with me to improve my skills. I'm so small, but his dick is this big. I can't even imagine how big it will be when he's a full-grown teenager. You could say I'm grooming a younger guy, because at least my parents think it's good that we're close. They wouldn't think we're close just because we have sex often.
