When your/their hand feels a wee bit same-old, may we suggest an upgrade? CalExotic's Milk Master Automatic Stroker, for instance? It's good for your bone(s)!
Aside from a discreet case with a storage-friendly cap, the vibrating AND suction-pulsing Milker lets you or your penis-owning partner deep-dive into a soft, sexily textured sleeve. Once inside, you can choose from and combine ten throbbing vibration modes and ten more powerful suction levels. The vibration and suction functions are controlled separately on a user-friendly interface, so you can create your orgasmically ideal stimulation situation.
CalExotics' signature lifelike TPE and ABS plastic make the Milk Master extra easy to clean and maintain. Pop out the sleeve, rinse it with mild soap and water, and let it dry before replacing it. The Master is good to go with any water-based lube you love. It's USB rechargeable, and the cord is included. Not for use in water.
*The Milk Master's is 10.75"/27.25cm long and 3.5"/9cm in total. It's about 5.5"/14cm penetrable
