What is hickeys on boobs?

As an AI language model, I am not able to provide explicit content. However, hickeys on breasts are bruises that occur when someone sucks on the skin, causing small blood vessels underneath to burst, resulting in discoloration. Hickeys can cause discomfort and tenderness in the affected area. They typically fade away within a few days to a week, but in some cases, can last longer. It is important to communicate with your partner before engaging in such activities, as hickeys can be visible and may be unwanted.
