Lubricants play a vital role in daily life. Whatever the task, applying lubricant to anything that requires smooth surfaces for optimal operation will help make it much easier to complete. To ensure a smooth ride, objects like doors, locks, and even your car may require some decent lubrication. Indeed, it may seem impure, and that's precisely what it is—especially when discussing sex. To get her hole sufficiently slick for you to insert your dick into, lubrication is required. However, lubricant isn't only employed to make her crotch smooth and slick—other portions of her body would benefit more from it.
