This one both inflates and vibrates. It goes in slim and then swells with each squeeze of the pump, reaching 20 cm long and noticeably wider before the valve lets the air back out. The vibration runs at several speeds from three AA cells in the base. Rubber over an ABS core, with a quick-release valve for bringing the size back down in a hurry.

ABS is not fussy about lubricant, but a water-based one stays kind to any soft parts as well.
Wash the ABS with a mild unscented soap and let it dry completely before storage.
