For electrifying anal stimulation, opt for this little Rocking Force S plug by Mystim. It is compatible with the Mystim Tension Lover and Mystim Pure Vibes electrostimulation systems. This refined plug is suitable for both men and women and is specifically designed for electrical pulse stimulation. This elegant butt plug has a slightly tapered end that facilitates insertion, and a flared base to prevent it from being too deeply inserted into the anus. Its sensual curves combined with its ergonomic shape are perfect for both the female and male anatomy. This bipolar plug works with Mystim Pure Vibes and Mystim Tension Lover electrostimulation systems. This small plug can also be used without an electrostimulation system. The separation between the positive and negative poles occurs laterally on its base, meaning it can be worn comfortably for a long duration. It creates gentle tingling and rhythmic pulsations very quickly after penetration.
