So your female submissive is in her 40’s to 50’s and her levels of hormones have been shifting all over the place.
One bonus might be a drop in estrogen which causes the progesterone levels rise, triggering her nipples to be more sensitive. Perhaps her nipples have been a non-entity for years and now they are front and center – literally – shape and size. Something that has been numb in the past, has become incredibly touchy – which makes for another dimension in play.
Go cautiously, but the bodily change might offer diversity and delight for both Dominant and submissive!
