The origin of this relationship.
As male foxes cross-bred with mousettes, vixens started to feel yiffy desires towards the male mice. A few years
after the M Fox/Mousette relationship was first created, a group of about 6 vixens wanted to be yiffed by a male mouse.
At first, when the vixens "caught" the mouse, that mouse was afraid for his life. However, they only wanted yiff and
had no intentions of hurting him. The mouse yiffed all six vixens and ended up impregnating them all, resulting in the
birth of over 40 children (both foxes and mice). The vixens were so happy that they told their friends and the M Mouse/Vixen
relationship started to increase in popularity after that.
Why they cross-breed
The main reason why M Mice and Vixens cross-breed is because they enjoy the feeling of yiff. The vaginal walls
of a vixen are very hot and tight (designed to accomodate a canine knot). This makes the naturally yiffy mouse even
more sexually aroused. In addition, male mice produce a large amount of very high density semen that is designed to
stick inside a female.
What they offer each other
M Mouse: Very High Fertility (male mice can put up to 2 BILLION sperm cells into a vixen, male mice can also yiff a vixen
several times in a short period of time*).
Vixen: Highly yiffable (vixens are very hot and very tight, non-canine males can be aroused quite quickly when yiffing
a vixen). Warm and thick fur (especially during the winter), vixens will allow male mice to snuggle with them if they
Unlike Earth, foxes do not eat (or intentionally harm) mice. Their natural instinct to pounce on and kill mice
has been converted to a natural yiff instinct. There is little danger for a male mouse in a yiffy relationship
with a vixen**.
