epikurean66  Simply the best and most sensuous stimulation you can get. For SP or Petting (wich is underrated!). If material is exactly up to your taste it gets irresitible when lubed (waterbased glide-gel) or lubricated (precum/pussy-fluid). There's quite a range: Rubber, Latex, PVC, PU (Polyurethanes) TPU / EPU / PUL (PU laminated textiles), EVA, PEVA... even 'inside Polymer coated Polyester Sweat/Shape Wear'... material simply needs to be fluidproof to be: LUBE-ABLE & SLIDE-ABLE - and soft, flexible, with a smooth and pleasing tactile surface.
Sexy cut and transparent / translucent PU and PVC foil panties can look incredible! - so they look exactly as hot as they feel and anyway always feel as hot as they look! With all respect to those who needs diapers - even a snug diapercover - without diapers it is something completly different! - a gender neutral genius sextoy! If you dont believe - you'll feel the difference - as soon it touches your crotch....

epikurean66  Absolutely love your picts! Thank you very much! By the way (because of your hot cameltoe picts) Do you know about 'PlasticPanties'? ...lubed used as 'LubeWear' underneath any 'CameltoeWear'? - of course, without diapers! - maybe with glidegel - snug to tight... even the tiniest slidings when you move feel incredible! - the wetter the better! - till showers of pleasure through your whole body - geniously, viskous fluids are perfectly hold - but take good ones - made of TPU or EPU (KETUOXUN TPU PLASTIC PANTIES CLEAR - no plasticisers, fluidproof & breathable, soft, smooth, pleasing tactile, slight translucent & pearlshimmery - or the even thinner chewing-gum-pink, opake EPU one...)

epikurean66  Mmmmmh... next time you should go for a "slippy-yippy" tribbing with all that cum... ;P
