Keitaro was walking by and saw Naru take her shoes and socks off at the park. Naru was dressed in a sweater and short skirt. she laid down on a bench for a nap. Keitaro thought of an idea. When Naru woke up, she was tied to the bench, barefooted, and Keitaro in front of her" Keitaro! What are you doing!?" She shouted. "This is payback for all the times you called me names and hit me." Keitaro added. "Oh no. you're not thinking of tickling my feet are you?" Asked Naru. "Yes I am!" Keitaro said. Naru begged and apologized, but nothing worked. How do you want Keitaro to tickle her feet?
