From a latex playtime session...
No more news from the 'mass measurement' exercise - apparently it's still in the making!
BUT... a new one was taken - the circumference of my head (it's 21.5 inches) - SG won't tell me what that's needed for.
AND... SG's latest purchase for His pup is a pair of leather bondage mittens. They are in hand (haha), awaiting my ickle paws to experience them this weekend.
