Otaku Odyssey Series Vol.2! This series isn't just about cosplay sex; it immerses you in original stories with homage elements. Introducing "Yoasobi no Utage"… Recently, salaryman Kaz has been unable to sleep. He's been spacing out at work, making mistakes, and eventually skipping work to drink. One day, Kaz meets Monaka, a free-spirited girl he's never encountered before, and his heart is stolen. From that day forward, the two spend every day together. Inspired by Monaka's freedom, Kaz vows to become a vampire himself. However, there's a condition: "You must fall in love with a vampire." For Kaz, who is bad with women and uninterested in romance, this is no easy task. Days pass with no sign of Kaz falling in love, so Monaka takes matters into her own hands with a direct invitation, "Hey Kaz, want to fuck?" "Maybe if we fuck, you'll like me." Despite Kaz's confusion, Monaka pushes him, and the shy Kaz can only cum from the blowjob. Then, Monaka masturbates lewdly in front of Kaz, finally flipping his switch and turning him into a man!
