N.) Dog N Suds is the act of fucking a female
in the ass, or vag. You then pull out, and proceed to bust-a-nut in her ass crack. After busting said nut, you lay your dick in between her
ass cheeks. Once this is done you start lightly, or heavily running your dick through her crack, similar to
titty fucking or such activities.
Vuahla, you have just committed a "Dog N Suds"
