Out of every sex toy I have bought sadly this was the most underwhelming which is sad because it was the one I was most looking forward to. When used even at max it tightens you up for a few seconds then just feels warm nothing else. Tried on many different modes and still didn't even help. Just using this as a standard plug was more enjoyable.
The Intruder is massive but with care can be inserted up your arse without much pain. The neck of the butt plug keeps your arsehole nicely stretched open which you can see by looking through the acrylic isolating strip.
Using the powerful SensorVox electrastim unit, the Intruder literally light up my arse with insane electrical buzzes causing it to contract/pulsate in rhythym.
