THIS WAS GREAT!!! straight dude obsessed with pleasure finds out about the pleasures of a prostate and a dick in him and gets into a sex buddies relationship with a digestive system doctor. feelings eventually build up. the uke is beefy and horny and the seme has long hair. this is literally perfect. too bad the author's other works aren't :/
