The best gets even better with the Cock Teaser Attachment for Merci Power Wands. This tight, textured head stroker stretches to form a snug fit in clear material that leaves nothing to the imagination, and is designed to perfectly fit the Power Wandb s formidable vibrating head. The textured opening of the Cock Teaser gives way to extra large pleasure nubs and finishes with a suction-creating closed end.
