Question: Will it fit...

up my bottom?

I dont mean the space invader machine - I know that fits already... I mean the buzzy thing?

depends - yes it will fit but the hairs and skin are extremely sensitive that it's better to hot wax than anything

Generally people will use strip wax for larger surface areas. So that's the more common one used on legs and the chest area. This is because it binds itself to the skin and removes a lot of hair, very quickly. It's not great for delicate skin so opting for hot wax would be best for your butt

The anus' ability to stretch itself never ceases to amaze/trouble me so . . .
