Plugged at the office for hours

I am looking for a nice buttplug I can have in for an extended period of time.

I am currently using a weighted plug and it only makes me feel “filled’ but doesn’t hit my prostate at all.

I am looking for something that will give me a little zing of pleasure. Something that I can secretly rock in my office chair and get pleasure, or feel it hit my prostrate when I walk.

I have the helix syn and that doesn’t seem to do it for me.

Maybe I am not using it properly. Or the helix syn is not the proper one for me.

Any help would be great, thank you.
