Some dildos have tubes in them you can pump fake cum through. Cum lube would be something you pump through the dildo while you're using it for lubrication.
I always thought the blue one was gay and the green-purple joining twins were hermaphrodties. It's safe to say that my confusion in terms of sexuality and my faggotry was born off of things such as dragon tales. As time progressed and I grew older, a change of ideology was brought forth in my mind and the male gentalia went from 2/10 would not touch to 7/10 would poke with stick. Society placed a very dense perspective on my mind and what is right and what is wrong, therefore the rainbow on the magic stone might have be representative of my life, but who knows. As I ponder these questions I stare out my window on a rain day and fondle myself softly like a bug, softly....like a bug.
