Noah-chan is a shy high school girl who likes dicks and was peeking at the bulges of boys while they were changing. As she watched the boys change with their tops naked, Noah-chan suddenly wondered, "Why do guys have nipples?" She had learned that men also find nipples pleasurable, so she tried it out using the nipples of the boys in her class! "Oh, when I was playing with their nipples, my favorite dicks got hard! It's fun!" She straddled the dicks and inserted them in a cowgirl position. While pinching her nipples, she pounded them with a piston and ejaculated inside them!
