The Aneros Eupho Trident is a sleek and powerful toy. It’s the smallest prostate massager in the Aneros line of products. The Aneros Eupho Trident is an analog toy (e.g., non-powered), so you don’t have to worry about running out of juice. It is agile, long and thin, and has graceful curves for targeted stimulation. It has a smaller frame which makes it an ideal toy to use during intercourse as it moves through the thrusting.
