For a non-erotic massage, I love a good Thai style massage where the girl walks on your back. The skill comes from being as good with her feet and toes to read the musculature and tendons as if she were using her hands. With the added body weight controlled with handholds overhead, your muscles and joints are kneaded and stretched to blissful oblivion. Warning: do not do this massage as foreplay. You will be too relaxed to actually ‘play’.
