Brother,
There are many people who have lactating milf fetish...
I had booked a lady for night and she turned out lactating one. Initially she refused, said she only allows to her kid, but later after few drinks she allowed to suck breasts for all night long.
Things don't work out always as per your theory..
Firstly this is not my theory it is something that has been found out, tested and proved by Medical Scientists. Like International Medical Scientists and Labs. secondly even if you like a cattle sucked her breasts all night that would have still not infected you unless you have of habit of inserting your dick in any pussy you find in your way just to get rid of your sexual urge. If you are poor in your googleing skills, reading skills and comprehending skills I think you need to start as a child again going back to from where you started. Because I already said Google it.
