Fire and Ice

Annie and Nunu never saw eye to eye, this was natural for a young boy who sat strapped on top of a Yeti all day. Tibbers and Willump the Yeti actually got along fairly well, so well that despite their inhibitions the children oft left them to their own designs while they were alone. It always went the same, they would sit around and converse using some form of Animal gibber gabber until Willump leaned over and let Tibbers go at him, which he always did. Tibbers enjoyed the accepting depths of the Yeti's rear, he found it fit snugly over his bear cock.
It didn't take long before they were both finishing, spraying semen everywhere, but they cleaned it up relatively easily thanks to Willump's snow white fur. It always ended the same, though. They would get interrupted somehow, and would have to use their contingency plan.

Willump would swallow Tibbers whole.
