The Milfs, in their bras and thongs, take turn to pour buckets of green slime over each others' bottoms.

Then when 2 of the milf get turned on and start kissing, it should be a romantic moment... but the other milfs can't resist dumping a bucket of thick green slime over them.

Then all bets are off and the milfs all get naked and start writing around and playing in slime, striking erotic poses and rubbing and pouring it over themselves and each other.

An amazing end.
