Everything went according to plan in the chemical laboratory. The botanist and his assistant were conducting experiments, pouring reagents into test tubes and beakers, when something amazing happened. Probably, the fumes had such an effect on the poor professor that his pussy simply could not stay in his pants and burst out. The poor assistant took one look at him and realized that she had never seen such a size before. And if so, then for scientific purposes it is simply vitally important to now see what this wiener is capable of!
