This sounds a very obvious one, but to start off...

Casts =B

Hehe. Yes! A thousand times yes. I don't really understand what I like about them, but they've been a kink of mine since forever.

Goo?

Sticky goo like melted marshmallow or flour dough. That's about it, sadly.

Awwwr. Not Jencen-Goo then? ^_~
Can be more sticky ^_^

What about this??

Holy crap. I didn't see your reply for like, 6 months, sorry. Afghanistan kinda crimped my FA browsing.

I like plump, oversized packages, but it has to be believable big, not crazy big. Oh, and flaccid. Erect cocks are a massive turn off for me, especially when the amount of blood required to make said cock would likely have led to the character attached to it dying from blood loss. I mean, seriously, if the thing's bigger than you are then getting a hard on is going to be literally fatal. Good example of believable: http://www.furaffinity.net/view/6443497/ Oh, and plump foreskins are <3

You and me both. i love casts as well. its nice to see others in the fandom with the same interests. i thought i was alone
