goldenghouls: I've been a D cup since I was 13, and I love being on top. My boyfriend dated A cups before me and he loves having me on top and having something to watch/grab on to. For the ladies that complain about their boobs hurting while they're riding: just hold/squeeze them with your hands. Your man will love it. Letting them bounce is definitely fun for a while, but I always end up holding them or putting his hands on them. It's sexy and you can still enjoy yourself!
My sister just told me what she does lol I asked her in person, she had a natural D cup as well. She uses her arms to each side of her to hold them in place.
