Zara’s recently increased body weight made her an ideal subject for the next wedgie stretch test – she definitely doesn’t need weights attached on her to have a chance against those heavy duty undies. So much so that by the end we needed to put three panties on her at once to keep her longer in the air.
Strip tensile testing is the most commonly applied test method for analyzing the mechanical properties of fabric materials. Tensile testing measures the force needed to elongate and break a sample. It is used to determine the strength and elasticity of women and woven fabrics.
After this session Micha said that she would never wear panties again, ever, she did not think that they could cause her such an agony. She stopped the session several times because she could not bear the pain. Her lovely girlfriend Jessica cruelly pulled her up and kept her in the air while the only thing that held her was her underwear which deeply and painfully cut into her pussy until it torn and she fell down. Since Micha is a very small and light girl Jessica fixed some weights onto her ankles because otherwise the panties would have never broken apart and she would have stayed in the air forever, in the most horrible agony that she could not have imagined.
If it’s about science, me and my girls are all in. We fucking love science. But science demands sacrifices, for which I am ready to commit myself. I sacrifice Tanita’s pussy on the altar of science – and a big bunch of her panties. Let the pantie structural analysis begin!
My new guinea pig of the tension test experiment was Jeby. She was not so lucky than Nazryana in the first experiment. The panties proved to be too good quality to rip. So she had to spend considerably much longer time in the air hanging up by her pussy on a very thin piece of clothes material. She was almost cut half by some of the panties lol. Have you ever thought that these little piece of sexy undies can cause so huge pain to the girls that they are screaming and crying in agony? I am sure that none of the girls who applies for this experiment ever thinks about that.
I used Nazryana as the main part of a home-made quality check machine that was developed for checking the quality of different kind of panties by applying tension to test the strength of the materials. Nazryana’s pussy got pumped up to make the experiment more interesting. Finally only one of the panties passed the test. Check it out which one.
