to TheSublimeSadist :It's both beautiful and HEALTHY for the not at all fragile udders ! I'm PROUD to say naturally my lovely 3rd wife ENJOYED to get an even worst treatment every Saturday, publicly in full sunlight. Vigourously shaked by two young boys together, in standing up position in order to improve the nipple activity her superb endurant well trained small boobs SPINNED AROUND in every directions... She never hesitate to request 'harder' to the two young men until her udders became as fully RED as her byuttocks...
