>>81677742 (OP)Anon, you're new to this but that's perfectly normal. Most nipples start out that way and get turned into protruding nips either by themselves or after the first few times of getting their nipples sucked on. Count your blessings, anon, your gf doesn't seem to be a used up slut and it's your turn to turn her nips into protruding nips by ferociously sucking on them. She may say it's a bit uncomfortable but don't let her detract you from turning her into a real woman. She will be uncomfortable for a bit but you really have to suck HARD on them but she'll thank you later for turning her nips outward.
Godspeed anon, we count on you!
