umm I'm not sure specifically but I've got the large contoured cups and tend to start with them as centrally placed as they'll go (with lotion, seen from above nipples would be tending to be towards the lower edge of each cup and the outside edge of my body i.e. (. )( .) before I start pumping
As I pump, thanks to the lotion the cups seem to find their own place and there's not really much I can do about their placement as the suction builds, but even then my nipples tend to be looking down and out in the cups. That could be to do with having a male ribcage though.
As for pumping I start off gently, just until it's no longer comfortable and then back off a little till it is comfy, and then gradually increase suction over the course of an hour or two, occasionally backing off and re-pumping and topping up lotion. I'd read that massage can be an effective technique on its own so I figured a bit of pump-and-release would largely mimic the effects of massage.
What's interesting is that recently I noticed that doing a session and then following up a couple of hours later with another session (i.e. before volume had subsided) seemed to have a cumulative effect and the results seemed to last longer too. I've actually noticed now that I'm holding some volume into the next day if I last pump before going to sleep. I work from home mostly on a laptop so I get quite a lot of opportunity to pump.
It's worth noting that bra is very flattering too - it was originally a sort-of peep-hole not-quite-even-a-balconette style thing donated by my gf where each cup was two halves which were joined with a bow in the middle (i.e. two not-quite-quarter cups effectively). I got the impression nipples were intended to be showing with it as per its original function. I removed the bow and sewed up the edges so the cups are now one-piece and it seems to have *just* the right shape for me although by now thanks to recent noogling my nips don't quite tuck into the cups anymore after pumping \o/
I'm also corset training and I think the corset might also make sure there's optimum amounts of volume to fill the bra...even so, before the noogleberry I wasn't able to get pics like that..at *all*. And the feeling is just amazing. I very much liked my f-cup silicone forms but they're untouched since getting the NB.
I think on one of the other threads ("amazing results" by sunsetz) she mentioned drinking a lot of water and also having a day's break from noogling now and then, both of which I also do, along with 320mg saw palmetto twice daily, massage with lotion+fenugreek seed tincture and further fenugreek tincture applied over arms and legs so it absorbs straight through the skin, thereby hopefully skipping the supposed 80-90% filtration by my liver as it would be if swallowed.
I hope that helps - Happy noogling
