[color=#006FFF]To answer the first question regarding breast foreplay and stimulation...
As someone who actually enjoys teasing and foreplay just as much as the sex itself, if I were able to make a woman orgasm simply from groping and caressing her breasts, I'd do that to no end. Teasing is incredibly enjoyable, even beside the simple fact that it could involve petting. It's more of the idea of getting a woman to her limit--to the point where she goes from being slightly aroused to being at the peek of their state of arousal, possibly leading to them wanting to go further and become more dominating or "into it". This, I feel, would result in much better sex for both people.
So, to reiterate my thoughts on breast foreplay specifically, "if I were able to make a woman orgasm simply from groping and caressing her breasts, I'd do that to no end."
[color=#006FFF]Regarding the current topic--one that I was actually thinking of asking some weeks ago, my thoughts are more or less the same of the general consensus. I find literal nipple fucking to be not only strange and to be a turn-off, but it's just disturbing. The idea of it alone is enough to make me cringe, but seeing it in hentai just looks dumb. It's one of the few things involving a woman's bosom that I just don't find enticing in the least.
And lastly, Gil's signature is indeed quite glorious.
