The Booty Booster
For fans of butt stuff and everyone else with good taste, this little accessory comes with some big benefits. The Booty Booster is an anal plug about 5 inches long that, once inserted into the targeted butt, can provide unique benefits while the target is under the influence of someone with a MCR. The Booty Booster is the perfect choice for all your ass-related modifications!
Features include:
-Easy installation! All you need to do is insert it into your MCR and project it into the targeted butt! You do not need to be wearing the MCR, just hold it in your hand and concentrate. Removing it is as simple as saying "Return to sender" into your ring and it will reappear in your hand.
-Perfect Anal Seal! The target will be aware of the BB, but will be unable to pull it out or try to remove it in any way. Also, while it is inserted, the target will fully absorb all food they eat and thus will no longer need to use the bathroom. Anyone other than the target will not be able to see it or interact with it.
-Adjustable Anal Pleasure! While the target is plugged, you can adjust the target's rectal sensitivity with a dial on the back. This ranges from being as sensitive as a pussy to being painful to the point of almost blacking out from the slightest insertion. The BB can also act as a vibrator, grow or shrink in size, change shape, and grow a fake animal tail for petplay.
-Complete Booty Control! While the BB is inserted their ass will be under your complete control! With our companion app, you can change their ass's size, bounciness, tightness, anything that you feel needs to be improved. You can also make them crave anal, twerk whenever they hear music, and **** them to flash their ass on command!
-The Booty Call Feature! While a victim is plugged, you can whisper "Bring me that ass" into your ring and your target will be compelled to come to you, ready for sex whether they want to or not. They will not remember the sex session afterwards unless you allow them too. Alternatively, this can project a portal to the targeted location that they will insert their ass into, projecting it to within easy reach of you.
-The Fun Doesn't Stop on Removal! All changes made while the BB is inserted are permanent. Removing it keeps the sensitivity, physical changes, and any custom triggers or commands you installed via the app. The BB is reusable on as many targets as you want, so reshape all your favorite fuckbuddies into your dream butt-sluts!
-Combo options! Some variations of the MCR can use unique capabilities of the Booty Booster© for added benefits! For example:
The Breeder Cock Ring lets you turn your target's rectum into a second womb (or first womb in case of male pregnancies), completely rebuilding their organs from the ground up. They will have no ill effects from this change and can experience multiple pregnancies at the same time.
The Cum Addiction Cock Ring can make a person addicted to receiving or giving anal or analingus. They will have an overwhelming craving for a tongue or cock in their asshole or will find your ass the most delicious thing in the world (or the best thing they have ever fucked), and will have withdrawals if they don't get their daily anal sex.
The Free Use Cock Ring can make everyone around the target desire the target's ass. They will be unable to resist having anal sex with anyone who asks for it, or from having their ass eaten by complete strangers.
The Total Domination Cock Ring can **** it's victims to feel actual pleasure from being spanked, on the same level as jerking off or fingering their pussy. They can orgasm just by being spanked and will come to find it pleasurable even without the BB's influence.
