JUR-785 - My stepmom is unsatisfied with my dad, so she sneaks into my room for more

The same director's 'Mother-in-law, you want a child, don't you?' series felt mediocre, just following other series with its second-half sex scenes where the stepson overwrites the husband's creampie. This work, however, digs deeper and improves upon that. The premise of a frustrated housewife who wants a child but can't conceive due to her husband's ED is common. I expected a typical nympho story, but the M-leaning development where the stepson, having sensed her frustration, forces a creampie on her ovulation day was a pleasant surprise. I highly rate the 'sandwich' idea: having an 'alibi sex' session with her husband (who took ED meds that night) and then being forced to conceive by her son both before and after. By inserting a bath scene after the husband's session, the film avoids the gross trope of the son licking out the father's semen, which is much better than the recent 'I'm always creampied by my father-in-law after sex with my husband...' series, which has become sloppy with such details. From the middle onwards, it follows the nympho title, but it stays consistent with the 'sandwich' creampie direction, which I appreciated. The ending's 'pregnant belly' effect is sloppy, and a woman who desperately wants a child having creampie sex while pregnant (with miscarriage risks) isn't very erotic. It would have been better if the child had already been born, and the son kept getting her pregnant year after year while failing his entrance exams, forcing her to have a second or third child. There's still room for improvement, but since it offers ideas beyond just copying others, it's worth turning into a series. I'm giving it 5 stars, with a slight bonus for the potential.
