What can you use besides lips to make it feel like someone is sucking on your nipple?

You can use various soft objects or materials to create a similar sensation, such as a gentle suction device or a soft cloth that mimics the warmth and texture of lips. Additionally, using your fingers to pinch or lightly pull can replicate the feeling. Experimenting with different textures, like a warm washcloth or a soft toy, may also enhance the experience.
