This classical duet entails a 10" x 1.5" multi-speed power vibe teamed up with a 7.5" x 2" gelatin rubber vibrator sleeve with sensuously arousing bulging vein texture. Just lightly lube the shaft of the vibrator, and the sleeve slips on to produce a big buzzing delightfully plump cock to fulfill your desires. 2 "C" batteries, not included, produce the wonderful vibrations. This duet also comes with .5 oz of lubricant.
