Yuyuko and Eirin makes me a little nervous here.

symmetrical_docking or asymmetrical_docking ?

Discuss.

Where is the guy this penis is attached to?

Is there a guy at all?

Is this penis disembodied actually?

What sort of position would it take to get your penis there while surrounded by 5 girls?

A position such as in post #1044529 probably.

link to the doujin, sadly it doesn't appear to have this type of scene (unless it's not in the samples)

There isn't, only in the cover. They only have individual scenes.
