Titty fucking can be oh, sooooo kinky but is always best done with nice, big firm jugs. In fact I consider it part of the ultimate sex therapy. If a girl has flat, shriveled raisins tits, why even bother?

Teacher sex stories and lessons that revolve around firm large tits are always fun to teach! You know this already from my previous nerdy kinky sex stories. Especially when they’re told by Slutty Geeky and Sexy Professor Carmen.

This particular naughty math lesson follows from a previous one and is bound to become one your favorite teacher sex stories. So since you (might) have already taken that lesson, it should be really easy to solve, right? And if not, well, here’s your chance to earn a free sex video with your next call.

Also, this lesson should help you decide which girl to pick up at a bar if sticking your dick in a delicious pair of tits is part of your plans.

In other words, my dirty teacher sex stories always help YOU out in the end. How so? If you’re ready for yet another good mind fuck, keep on reading!

Once again, let’s say you are talking to sexy, slutty twin blondes at a bar. They both have breast implants in the shape of spherical domes.

The diameter of one girl’s breast is d1 =  5 inches and it extends outwards to a distance of s1 = 10 cm from the center. The other girl’s tits have a diameter of d2 =12 cm and extend to s2 = 3 inches.

If your goal is to cum on the largest tits, which girl should you take home? Refer to the following diagrams for clarifications:

Yes, I agree that it’d be a lot more fun to take BOTH girls home and turn these teacher sex stories into group sex stories! But for now, back to the problem at hand.

Here are a few simple instructions you can use, should you be UP for the challenge…

  • Convert all inches to centimeters; 1 inch = 2.54 cm.
  • Remember that the radius is equal to half of the diameter.
  • Use the formula for the volume of a dome with each girl’s measurements to calculate how big her deliciously bouncy tits are.
  • The formula for the volume of a dome is V = 1/6{πs(3r2 + s2)}.
  • Pick the girl with the largest volume, take her back to your place, titty fuck the shit out of her and make her your little cumslut!
That’s it! How fucking easy was that?

So which girl did you choose in order to have a bigger BLAST (all puns intended)? Get a short sex vid with your next phonesex call if you get the right answer!
