Male Strokers, and Masturbators
There are all kinds of different masturbators and strokers. Some looks like mouths, butts, vaginas and boobs. Some have different sensations from having bullet vibrators to make them vibrate different ways to having flexible cups that they sit in so that if you squeeze it, it feels like a woman when she is cumming and her vagina is tightening around your penis. Some have rib bits and bumps in them to give pleasurable sensations.
