Lesbian sex toy

So my and my girlfriend both really enjoy clit stimulation and the position i think is most intimate is when we scissor. We're flexible enough to scissor and still hold each other and kiss. I like to put a vibrator between us to increase stimulation and pleasure but the shape of them makes it hard to keep in place. Anyone heard of anything better for the job?

A wevibe might work, its a couples toy made for use during sex, one partner wears it and will get internal and external stimulation while the other partner still gets the external stimulation?
