START-309

Synopsis: Riko, an active dark-skinned girl, visits the homes of troubled men to help them improve their premature ejaculation! The tour started with the idea that if they could hold back their ejaculation, she would swallow it as a reward, but Riko, who loves swallowing, doesn't let them hold back and makes them ejaculate right away, swallowing all of their semen! The director laments that this isn't working. What on earth is going to happen...?
