To thrust the penis between a women's preferably large breasts and ejaculate on her chest and/or face. can be used as a noun or a verb. (explanation for the sex-impaired: breasts contain milk, and you bone them, hence the term "milkbone")
Hey Angi, i would really like to give that large breasted lady a milkbone.

Tom really enjoys milkboning his wife, who i am told has relatively large breasts.

slathering one's genitals with a substance attractive to canines (or felines if you like the scratchy scratchy) in order to entice the animal to lick and orally pleasure your junk
After striking out with ladies at the bar last night Tim went home covered his flesh cudgel with peanut butter in order to get milk boned into ecstasy.

Because Tim's wife had a headache, he dipped his nuts in chocolate sauce for a good milk boning by the dog (BE ADVISED: Chocolate can be toxic to dogs, we do not advocate chocolate for milk boning with canines).
