The Price of Dreams by Antalios

A really kind of wholesome skinsuit story following the seemingly always perfect Ana, a top student and her classmate and good friend, Zoe. What nobody, except Zoe, knows, though, is that Ana is actually a boy named Andy, and with his nearly perfect skinsuit helps live out Zoe's dreams. The fact that Ana seems to be mute the entire time for some reason, is also quite special, and it adds kind of a nice bondage fetish element to the story.
