One does not need to be terribly limber to achieve multi-directional penetration with these variable-speed, bendable textured dongs. The 7 1/2-inch Cluster Probe, 6 1/2-inch Tickler and 7 1/2-inch Ridged Arouser all have a glittery, aqua gel body that bends and contorts to maximize penetration satisfaction. Bendy, twisty, happy.
