Yes, treat those nipples tenderly.  Use the tongue and teeth lightly and send little jolts of electricity here and there and if fortunate, into the pussy.  In turn, make those nipples harder.  We can see the crinkling skin there just beyond the nipple - that means arousal for sure...  So this photo was of a turned-on woman.  Wife is sitting next to me without her top and reached over and tweaked her left nipple similar to photo.  Skin began to crinkle.
