Well-formed muscles are his favorite thing! Kasumi’s hobby is observing the bodies of jocks while they play sports. One day, Kasumi sees a boy, Fujinuma, with a very shapely behind! Kasumi wants nothing more than to make a photographic record of Fujinuma’s perfect body… Not satisfied with just watching, Kasumi invites Fujinuma to his place. Beaming innocently at the flawlessly sculpted body in front of him, Kasumi can’t help asking Fujinuma to do something outrageous!
