Taste/touch test with girlfriend

I’ve been thinking about surprising my girlfriend one night with a taste/touch test. I was going to have her blindfolded and then bring out a sample of food for her to try such as strawberries, peach, chips, certain cookies/cake, etc. and then i would touch her with a feather, ice cube, marble, etc.

I need some ideas on great foods/objects that would be comfortable and possibly pleasurable. Please note, this is NOT SEXUAL. That means no dildos, vibrators, or anything else that porn stars use. It’s just going to be the two of us having fun and testing our "senses" if you will.

I’m also serious about this. Littlewing…i know you’re an expert so I’d love to hear from you.
