MIAB-596 - I allowed my father-in-law's dick to insert only 5cm into my vagina, and we were so compatible that we had a uterine love affair. Seeking deeper penetration... Rei Kuroshima

There are a lot of stories about craving the stepdad's package, but the actress's body really makes or breaks it. Kuroshima Reia in this one just doesn't quite have the curves, and the hair... it's just not my thing. Sadly, I'm passing on this one for my collection.

Similar to Attackerz's "If I let my father-in-law insert for 10 seconds..." or Madonna's "If I let my incredibly horny father-in-law insert for a while, we unexpectedly had amazing chemistry... we kept reaching climax after climax..." – another impregnation story. With this title, you'd expect a scene where the wife says "Just 5cm is okay" and then, driven by her uterus's desire, she starts begging for deeper penetration. But the portrayal of that struggle is weak, just like in the Tsukinoe Sui arc of "If I let my father-in-law insert for 10 seconds..." with the same director. The depiction of a woman's emptiness as her fertile years slip away, and the intensity of her hidden sexual desire, is much better handled in ""No... I'll get pregnant!" During the 20 days my husband is on a business trip, I'm being daily penetrated by his subordinate. Yuruyuru" which came out around the same time. Because I don't expect much from the actress's acting, the whole situation is driven by the male actor, and the 5cm rule doesn't function as a tease from the woman. Perhaps it's because the director doesn't often make works with a primitive "sex = reproductive instinct" theme, or maybe because they chose Tabuchi-kun, who's good at portio stuff, as the male actor, but the portrayal of the uterus's presence feels lacking. The initial penetration is also too easy, and doesn't really feel like insemination. The dramatic development of the conflict between reproductive instinct and reason is also weak, and the nude play in the middle is just a time-filler. The oral sex in the kitchen, followed by a kiss that tastes like semen, is just creepy. Overall, it feels like the creator hasn't fully digested the borrowed idea, and the quality is low. However, the ending is the best part – it doesn't try to wrap things up neatly, but instead fully portrays the dangerous, immoral feeling of an inevitable mess. If there's a sequel, I hope they focus more on the uterine love story, where the characters surrender to their primitive reproductive instincts rather than reason, and portray it more clearly both dramatically and situationally.
