How to touch my girlfriend's breasts.

How flat chested? If she's like an A cup, that would be easy. What I like to do to my girlfriend who is a 34B is I approach her actual breasts first, farthest away from the nipple, by gong under her shirt, and putting my thumb and forefinger under her bra, (the underwire,) and pushing her boobs up 2-4 times, but pulsing. Then I run my hands toward the back of the bra, and unhook it. Try to do this with warm hands, and this is all when you're kissing by the way. Then I go back to the boobs, and start rubbing, going slowly toward the nipple, and then just tickling the nipple with my thumb, while using the thumb and middle finger to hold the breasts up. You should be good with this dude.

yeah I love it when my boyfriend sucks on the nippes. (:

I really like when my boyfriend just rubs them. Or especially when he squeezes hard but not to a point where its like trying to rip them off. I have small breast as well, and he works quite well them. get one finger and rub the nipple with it.

Just work with what is there just like you would any girl with larger breasts. Stroke them, rub, squeeze, play with the nipples since they are a very erotic and sensitive part of the breast. Just convey to her that you love them, regardless of size. If you are going to use your mouth too, just kiss all over, and use your tongue on the nipples especially.

If she's flat chested, try using your mouth more. She might like that.

A flat chested girl is not handicapped or so: just do what you'd do with another girl. She will like it.
