Help me.

I think after a lot of consideration the board at least agrees that it should lead to you peeing in her butt.

The real question is how to get to that point. I'm still partial to my suggestion of course.

I guess so?

Post pix plz

I am not giving you pictures of any of my sisters.

Can't you figure something like this out for yourself? It's not rocket science, a monkey could probably do it.

Also, pee in her butt.

Then it didn't happen.

....? what?

OP have you peed in her butt yet?

That destroy the porn game is hard while jumping/firing/running. Had to use a controller.

What you could do is hide it in plain sight. I've had my volume of Velvet Kiss right next to all my other manga (such as Parasyte and Zetsubou-sensei) in plain sight and nobody has batted an eye. To paraphrase a quote,"To hide a tree place it in a forest."

Is your sister a fan of anime and manga as well? Because if not then that should work unless she's a very nosy person. If she is you could like carve out the inside of a textbook you don't use anymore. Or maybe a dictionary.

If all else fails you have to be the perverted onii-chan and fuck her into submission.

I will not bang my sister. neither will you cat.

Send the porn to me, and then bang your sister with a hammer.

B...But kira aneki-chan removed your penis onii-chan.

Plebeian.

I have way more than that.

Don't hide who you are. If you do, it makes that much worse when she finds out.

Suck her dick.

You must be new to the Internet. Pee in her butt.

Not necessarily new, just naive~

That said, pee in her butt and post pix~
