Jugs, commonly referred to as breasts, are mammary glands found in humans and many other mammals. They are primarily composed of glandular tissue and fat, and their main biological function is to produce milk for feeding infants. Breasts vary in size, shape, and density among individuals, influenced by factors such as genetics, age, and hormonal changes. In addition to their role in lactation, breasts have cultural and social significance in many societies. They are often associated with femininity and are featured in various forms of art, media, and fashion. The perception of breasts can vary widely across different cultures and time periods.
