Looking for a story where a brother teaches sister how to give a handjob

[DramaticSomewhere]

The sister has a new boyfriend and wants to give a good handjob, having never given one before. She asks her brother to teach her, so he does but only with his words, she never touches him. The whole process is very teasing and frustrating for the brother and he feels guilty about it.

She gives her boyfriend a handjob and then recounts the experience to her brother in excruciating detail, teasing him even more. She then records a video of her giving a handjob to her boyfriend and gives it to her brother to watch.

In the end the brother cracks saying how horny it's making him and the sister (allegedly) has no idea the effect it was having on him, and then tries to make it up to him by giving a handjob just the way he taught her, but the story ends there.

That's a fun little escalation. Alas, I don't know this one.

It is not the one you are looking for, but "My Brother, My Tutor" has a similar theme.
