Hi everyone.

In the past I visited shanachan from time to time. There was a kind of fetish board with different threads like here. One of them was called "Requesting Tubes" in which they shared drawings of girls (perhaps also males) with tubes connecting their anusses/urethras with their mouths to create a circulatory system. It was really devilish but alos somehow arousing to see.

Shanachan is down so I can't access those fetish board anymore. So if anyone of you knows what I mean and also has some of those pictures, please give me a link to them or post them here. Thank you
