At first glance, the RealCocks 6″ Thick Self Lubricating Dildo looks completely normal. It’s soft, plushy and shaped just like the real thing. Once it gets wet though, it turns into a slippery playground of texture and friction. Use plain old water or saliva to activate the self-lube feature. You can do that about 30 times before the material needs to be supplemented with actual lube.
