Answer 1

SFN = y + w (r x bc) +
where SFN equals spanking force needed
y equals yelps
w equals wriggling
r x bc equals redness of bottom-cheeks

Happy spanking!

Answer 2

I can actualy answer this. Go with a full vertical lift and let nothing but gravity carry the force for the strike. It will give the desired effect without causing bruising or tissue damage. Keep your fingers limp and slightly cup the palm.

Answer 3

You are really on a roll today with the S&M stuff!
Answer just enough to sting a little! Happy Spanking!!! :)

Answer 4

hard enough to wear you can hear it but dont reach back so far to wear you catch so much wind on the way that you put your whole force in it and then it hurts bad.Jus enough to hear the spank but not tomake a hand print. I am a girl and am telln you, dont do it to hard you'll kill the mood!

Answer 5

aright, well if you're vector is at a 90 degree angle you're gonna wanna apply about 1290 Newtons, that's kg-m/s^2... but if you're at 45 degrees, you're gonna need to double that to 2580 so as to apply the same forward motion and get the same results in the redness area. happy spanking.

Answer 6

There is no equation in this. You both need to agree a code word beforehand - simple as.

Answer 7

Just keep in mind that your not out to actually hurt her, just a little pleasure tap is all.

Answer 8

5 foot pounds of torque

Answer 9

Equal to the force you want your face slapped of course.

Answer 10

{size of hand} - {sensitivity of butt} x {degree of masochism of gf} = {force at which to spank}

I'm really good at math.
