[Yamaguchi Suguri] I'm a Sex Angel! [Incomplete] [Xiao's Yaoi Playground]

Alto is an angel-in-training with a heavenly mission: to become an archangel of Eros, he must descend to the human world and earn experience points through hands-on study of sex, and gentle Ousaka has agreed to become his very first partner. Between breathless lessons that leave the winged boy trembling and teary-eyed, Alto insists his feathers are no costume and dreams aloud of making all of mankind feel good, while quietly worrying that his devoted partner is wearing himself thin for his sake. A tender, blushing tale of a naive celestial student discovering pleasure one intimate tutorial at a time.
