Looks like someone is crowdfunding a sex toy that will vibrate/throb when you tap your tablet/phone while reading a story. So when the story gets good, your lady parts feel them too.  

Sexbots get closer by the day.

There's no need to buy all that high tech stuff.  You are free (and I do mean FREE) to sit in my lap and I'll tell you all kinds of dirty stories.  Maybe I can't vibrate exactly like that gizmo, but there's this thing I do while humming...  well it's hard to explain.  You just have to see it.  And I don't even require batteries.

But an occasional nap works wonders...

And let's not make it just about me - I'm sure any of the fine gents around here would be happy to substitute for that high tech device.  There's nothing like the personal touch.
