...on my balls or taint. I once bought a Fleshlight and that was fun for a while. Now they're making celebrity porn star Fleshlights with the molds taken from the stars' real life pussy.  

Love a good whack on the back!  

I do enjoy watching a lady riding a fucking machine. Or a lady double penetrating with a long double ended dildo.

Not so much a specific toy, but...

I had a provider who used a bullet vibrator in the backdoor while I went in the front.  That was freakin' incredible.  So, I guess my answer is anything that fits there!

But, I'm dying to try out a WeVibe.  I think that could be a winner.

Anytime I've given a Lelo toy as a gift, the reaction by the escort is usually OMG, I love Lelo toys
