As someone who has had a lifelong obsession with breasts (and breast play), I used to thing breast worship porn was where it was at. Nope. There is a whole genre of porn that's not really PIV porn at all, but just nude massage. The better the cinematography, production value, and actual massage is, the more satisfying the video is to watch.

They say not to have sex like you watch in porn, but let me tell you... my wife quite benefits from me trying to emulate this style of porn! We created our own massage candles (candles made from natural waxes and essential oils that can be safely massaged into even sensitive skin), and I can get completely satisfied by simply massaging her (if she's not in the mood for PIV sex).

That being said, I am still really into sensual breast worship. I'm also into adult breastfeeding/nursing, so... there's that as well. Story about that on my profile if you're at all interested.
