Your gateway to your first ballsex experience and your first ballgasm! your Balldo set comes with a Balldo and two spacer rings to ensure that you have everything you need to start having fun.The Balldo is made from phthalate-free silicone with a super stretchy upper ring to make putting the Balldo on and off as easy as putting on your underwear.Did you know that the male scrotal sack has virtually the same amount of nerve endings as the woman's vulva? This is because it's essentially the same skin as the outer labia just separated at birth as it were!When fitted to a man's scrotum, it will allow him to use his balls to penetrate his partner and release a totally new type of sexual experience and pleasure for both. The Balldo encapsulates the balls and presents them in a specially designed cage that allows them to be inserted and then thrust into a vagina or anus.Effectively your balls become a second penis, with their own unique feeling of stimulation for both the wearer and the recipient.The cage is very soft on the outside but internally is fitted with a strong inner core which ensures that the tip and side legs stay rigid enough to easily penetrate an orifice.The Balldo also ships with two spacer rings these are pulled over the Balldo and sit between its base and your abdomen. Their purpose is to take up the slack in your scrotal skin and extend the Balldo and balls away from your body to make it rigid against your abdomen and make penetration effective. With both rings fitted the Balldo is 7 inches long, the same as the average penis.You might need more or fewer spacer rings depending on how loose the skin is at the top of your balls.For the wearer, once inside, thrusting comes instinctively and bizarrely feels like normal sex. However, the sensation is very deep and unusual because your balls are inside someone and you are actually penetrating with them.This sensation can trigger what we have termed a Ballgasm.Ballgasms are slow building, long-lasting and earth-shattering as the body and mind don't actually know where the trigger is coming from. We cannot promise that you will attain a Ballgasm as everyone's stimulation points and levels of arousal are different.For the partner the Balldo is naturally nice, thick and filling, it's 2 inches in diameter so will be slightly bigger than most are used to. When the balls pass the wall inside you there is that satisfying plop feeling and the balls can clearly be felt locking into the anus or vagina kind of like a butt plug.The excitement of having a man's balls in your anus or vagina adds an extra level of arousal leading to unusual orgasms. For women, when in the missionary position with legs back by the head, the Balldo sandwiches the clitoris against the base of the penis and the spacer rings, this intense rubbing can lead to rapid orgasms.
