PPPD-726 - Surveillance of my step-sister's defenseless breasts

The actor playing the boy is so bad it ruins the mood. His lines are mumbled and hard to hear. Even the continuous sex scenes in the second half are clearly unaroused through the mosaic, which is a turn-off. Hatano-san's acting and her beautiful body are the only saving graces.

It's a bit underwhelming. The final sex scene was decent? It was intense and nice, though. Giving it a 4, with one point added as a bonus.
