18+ Nidoto Jidori Okutte Yannai!

Himari has never been one to abandon a friend in need, so when her friend Eisuke asks her for a selfie so he can use it as an art reference, how can she refuse? Even if it is...embarrassing... But what's MORE embarrassing is the kind of art he ends up drawing! But he needs her help, and Himari just can't say no, no matter how suggestive the poses get!
