The SOFIA clitoral vibrating egg, with anal stimulation,
is equipped with TWO very strong motors. The main one goes up to a
staggering 8100rpm, while the side motor reaches a mind-blowing 12000rpm!
All this happens with a very discrete noise level, never going over more than 50Db. Of course this wonder of technique is also equipped with 10 different speed modes for some real orgasmic action!
