Here are my impressions of 'Nana's Mouth Filled with Semen!' The work features charming and erotic PtoM missionary position sex, with scenes of Yagi Nana tearfully receiving semen being particularly noteworthy. However, there are opinions that the amount of oral ejaculation is excessive, with some voices calling for more facial shots instead. Especially the scene in the last chapter where semen is splashed all over her face is praised as a true facial shot. There are also scenes where the mosaic is thinner, making the anus clearly visible, so one can say that the overall quality of the work is high.
