Two rumbling motors. A shape that hugs your curves, hitting multiple erogenous zones at once. A sleek black design. Perfection. MISS BI – BLACK LINE overwhelms your senses, with two powerful, independently controlled motors that deliver deep, bass tone vibration to multiple hotspots at once. Try out a range of positions with this vibe’s firm-yet-flexible shaft and extension, which use FlexiFUN Technology™ to move with your motion and mold to your curves. And don’t be fooled by MISS BI – BLACK LINE’s modest size: it targets the G-spot and clit for maximum effectiveness.
