Cass Gogo And Honey In A Gang Bang [Misthiosarc]

If her friend, Helen Parr (Elasti-girl) was a part of this, I would guess this was her doing, since she does likely bang Frozone on the DL. But since she's not part of this..(this time) absolutely Cass's idea for this BBC orgy,

... definitely Cass' fault.

My guess is, one of these ladies (Cass most likely) had previous BBC encounter experience, and decided to let her nephew's female friends in on some action. This was the result.
