Well, I introduced them tonight, and so far so good. I'm surprised - little MADAM Faith actually stayed still and let herself be humped. I expected her to be dominant - turns out YUKI is!
All in all it was quite painless, and they're currently all flopped out. However, Yuki's little man is... well, a bit stuck. :lol: I'll leave it for a while and if it doesn't go down by itself I'll either vet him or try to help him get it back where it goes. :lol:
