How should a guy kiss a girls breasts?
There’s no single to this — different women have different preferences. I would suggest starting with something slow and gentle — just brush your lips around them and find the most sensitive spots (usually around the nipple, but there’s no guarantee). The tip of your tongue is another way to start. If she likes what she’s feeling, she’ll tell you, one way or another. Women tend to like taking things slowly, and breasts can be very sensitive, so let her call the shots. Once things get going though, don’t be surprised if she presses them into your face.
