New characters introduction? (Patreon)

Their names are Theresa and Melina. I'm planning to create another yiff comic (f/f/m) about them when the current one is finished (but there's a possibility that I'll reorganize my patreon and will work on two comics at the same time). Are their breasts too big, though? :p

What race would the male character be? Feline, canine, other? Tell me your preference ^^
