Hello,
I’m guessing most people on this forum are familiar with wearable devices such as we-vibe couples vibrators that a woman can wear (including in public) and their partner can control the device remotely.
Does anything like this exist which I can use one my partner while locked in Chasity. I think it would be fun after he has been retaining for a while to surprise him by connecting something that vibrates to the cage which I can control remotely.
I have this kinky idea of teasing him with it in a public place.
There are a myriad number of remote-controlled buttplugs - I have one myself (Ace Nexus Large) which is very stimulating indeed, especially when my wife has the button. Mine is fairly quiet while inside me, fine for outdoors, though in a very quiet room it would be audible. If he's not used to plugs I would recommend a smaller size in the same range.
I haven't done this myself, but a butterfly vibrator inside his briefs/panties/thong would, I think, work.
