I actually shipped something similar to this while working at Amazon this summer. The one I shipped was just called a penis enhancer. Here's a link to the first one that came up on Amazon. But there are a variety of similar things out there both on Amazon and on other sites.
I'm not sure what the official name for it is, but have you heard of silicone penis sheaths/extenders/sleeves? You just wear them over your dick and they enhance your size. I think they're good for a more personal experience than using a dildo on her. They're cheap on Amazon, here's a link to one so you know what I'm talking about.
Amazon carries these also.

Yes. Think of it like a strap on, but a hole for your tiny penis to go into.
Here's a nifty penis enhancer that might make things a little spicier.
They have stuff for that also. Size Matters Enhancer

Seriously... amazing, get the ring on your balls like a cock ring, then lube a semi erect cock and insert. May need to stick a finger down to release air and tighten. Fits great and it's AMAZING for her.
