It's all the rage on Second Life sex sims right now to use vibrators and vibrating cock rings that are operated remotely
by your chosen partner for that evening (often a stranger, often far from you on the planet). I don't know much about it (honest, I don't!); I just find it very interesting. If you're curious, I've managed to find a web page without pictures:
The video made it sound like this too was something you could, IDK, pre-program, at least. Or that the camera somehow communicated with the level of vibration? OK, I've watched it again, and, I have no idea what the point actually is. The woman still has to push the buttons when she wants more vibratin'.
