This is Tokiwaso, an apartment complex where aspiring female erotic manga artists aiming to make their debut gather.However, the editor in charge, Wakamiya, was worried about the girls' immature expressiveness, and in order to make the girls learn about real sex, he decided to use a male editor as a guinea pig to gain experience by performing various erotic acts!Using an editor with a big dick, everyone takes pictures in various positions and takes notes... I want to draw even more realistic and naughty manga!The passion doesn't stop at that day, but each male editor was there to study and sketched his dick standing up, the way her breasts swayed, the drooling threads of a blowjob, the way the sperm flies out at the moment of ejaculation, the way the sperm drips after being creampied, the transparent oil massage and deep throat!Chinguri cowgirl piston!Masturbation!Lesbian sex with everyone!!!etc...and finally a big orgy sex!!Will a popular erotic manga artist be born from Tokiwa-sou through intense orgasmic training??
