HSODA-117 - A week without dad, mother and son's repressed lust explodes

The plot revolves around a mother and son who both fantasize about incest, but their kinks are polar opposites: the son wants to be seduced by his mother, while the mother wants to be treated like a sex slave and impregnated by her own son. While the premise of them being left alone due to the father's business trip makes the incest a reality, the mix of S and M play feels scattered and half-baked. They probably did this to add variety to the encounters, but I feel it would have been better to stick to either S or M and vary it by production to create more series potential. The fantasy sex scenes were also strangely restrained for something that wasn't even real; leaning harder into the pregnancy angle would have been more effective as a buildup to the later sex scenes. While actor Horiuchi felt a bit off as the son in terms of balance with the actress, the performers gave it their all in both the drama and the encounters, which makes the scattered direction of the film all the more disappointing.
