One toy between two women
Lesbian dildo play puts a toy in the hand of one woman and inside the other, or inside both at once. The woman holding it controls depth, speed and direction with her wrist, and the toy changes hands so both take a turn.
A head at each end
Material decides how a toy for lesbian dildo sex feels. Silicone is firm but flexible and wants water-based lube; glass is smooth and heavy and can be warmed under a hot tap or chilled; a suction-cup base sticks to a floor, a wall or the side of a tub and turns the toy into something to ride. A double-ended dildo is long and bendable, so two women can face each other or kneel ass to ass, take one end each and fuck toward the middle. Next to fingering, a dildo adds length and girth but feels nothing itself, so the woman holding it reads depth from her partner's hips and breathing.
A toy with a flared base fits the ring of a strap-on harness. The same base keeps it from slipping too far during anal toy play. Silicone, glass and stainless steel are the body-safe materials, and all three wash clean with soap and warm water.
