Sync™ - Under the Stars - Cosmic Purple Edition is designed to be enjoyed with a partner during sex. She gets powerful stimulation to her clitoris and G-spot and together both share the vibe. No two bodies are the same. That's why Sync can be adjusted to fit your unique shape. There are two adjustable points to better target the G-spot and clitoris with more or less pressure. Sync fits comfortably in place even as you change positions during sex.
