Tenga masturbators offer revolutionary designs for the modern masturbator, and all the accessories needed. Simply lube up with some of their brand name lube and enjoy knee trembling sensations via one of their eggs or masturbation cups. Their cups work just like a sleeve, but there is a closed end as well. Tenga also created a warming wand for use with their cups. Simply slide it in before using their lube for that warm, wet feeling that you have been craving.
