Yukio, Kanna's Older Brother

Decided I wanted to write a story about Kanna and her brother by myself for others to read at some point. This is how I picture her brother to be! 

Name: Yukio
Age: 19-23
Height: 5'11
Penis: 6.5" uncut
Distinguishable features: freckles, wears contacts/glasses
Body Type: slender
Hobbies: video games, manga, anime, history, masturbating while thinking about his little sister

Kanna's oniichan (older brother) is a nerdy/geeky type of guy. He is a bit of a neet, otaku, and is a total lolicon. Kanna is after all the most adorable girl ever. All of the manga and anime he's seen hasn't helped either. He's noticed Kanna is around that age where she is starting to mature into a young woman so his chance of fucking his adorable sister while she is still a loli is running out.
For him to be able to live with himself after taking advantage of his little sister, she needs to get an interest in sex. A little coaxing from him can't hurt? Plus ee's not a total monster, he will make sure she loves how he makes her feel.
