Elastic bands experiment with my nipples

Description: I love a good experiment me, and one morning in the office i found myself playing with elastic bands and wondering what they would feel like on my tits and nipples.  i just had to find out! the experiment on my tits did not go to plan, but i have shared it with you here!  my nipples, however, were a great success!  they became hard and sensitive very quickly.  i should think if you were to have me wear these on my nipples whilst going about my daily chores, i would have a very focussed mind indeed!
