What is Mouth Breeder?
1.
A mouth breeder is a chick, involved in a MFF three way, that finishes off the guy orally. But, rather than swallowing the baby batter, she goes down on the other chick and spits it into her.
Tina took Bob's big load then spit it into Gina's snatch, what a mouth breeder!
2.
Oral participant in the Post-Coital Oral-Vaginal Swap. It is not known if an actual pregnancy has ever occurred in this way, or if the mouth breeder would be granted any parental rights.
This practice is not thought to be common anywhere save perhaps the porn industry, more's the pity.
A picture's worth a thousand words...too bad I don't have one.
