The A-Bomb by Tantus is an advanced level butt-plug. Its high quality and workmanship might take a while to work up to, but it is definitely worth the time and effort!
Unless this is your first foray into the world of anal play, there is no reason why you shouldn’t have this in your collection. Perhaps those who are new to this realm can start with A-bomb’s younger sibling B-Bomb and slowly build themselves up. I have not conquered the A-bomb myself yet. But from my wife’s experience and the effects it has had on me so far, there is no doubt in my mind that I will be trying again and again until I too can have this plug buried deep within me.
