I put an ad online for models to try out a new tickle experiment. The perfect model will be stopping by today for an interview. As soon as I told her about the modeling job she got scared and was trying to leave, so I grabbed her and knocked her out. She was too pretty to let her go. I tied her up in my bathtub and began tickling her. She was very ticklish. I removed her knee high boots and discovered she was wearing knee high nylon stockings. Perfect! That is just what I need for my experiment. I remove one nylon sock and put on a cotton sock to see which one was more ticklish. Looks like the nylon wins. I tickle her and pinch her nipples and shove the socks in her mouth. She tries to scream and get away, but she is no match for me!
