Gentle-to-medium pressure kneading motions that you administer to someone'
s shoulders, either to relieve aches/tension and generally soothe his overall physical/emotional status, or to simply savor his/her sinewy/pliable muscle-tissue (this is especially pleasurable if the
person is not wearing any covering on his/her shoulders, since it permits you direct flesh-to-flesh contact with your hands for maximum sensory pleasure, and it also lets him/her feel the caring warmth/softness of your hands). These simple massages can be administered to your friend from either the
front or the rear, although it is usually safer and more comfy for the
person if you do it from the
front, since this ensures that your fingertips will not accidentally dig into the tender
joint-grooves just below his shoulders.
I love giving shoulder-scrunchies to cute chicks whom I meet for the first time --- it harmlessly and unobtrusively builds her
trust and shows her what pleasant soothing "magic" I can
work with my hands, and so she will often permit me to gradually "progress" to other
juicy portions of her real estate until I eventually have her completely stark-naked within half an hour.
