The highly anticipated 5th installment of the popular incest series is here! Eriko Miura plays the beautiful mother who decides to give her son some hands-on sex education. As she guides him, she finds herself overcome with lust for his body. With her innocent looks and F-cup curves, she goes wild on top of him. This episode features the most intense impregnation and explicit dialogue in the series history.




















The previous entries in this series were strictly one-on-one, but this one features multiple partners. I was really hoping for some intense, focused training with just one person, so this is a letdown.
At the 51-minute mark, he drives it in to the hilt, leaving her soaked in Sayo Arimoto's juices. Then comes the doggy style. When he pulls out, her hole is twitching and gaping—it's so loose I just want to lick it. The fluids are dripping out, and she just stays there with her butt in the air. I want to whip her. At the end, there's a cut of an older woman putting a basketball under her shirt and muttering to herself—what was that about? Surely it doesn't mean she got pregnant from raw sex with a kid, right?
The key to this work for me is the balance between the mother's maternal instinct toward her son and her 'female' side. It's ideal to see her maternal love go so far that she starts acting like a female in heat. Eriko Miura's balanced performance was excellent. The premise of teaching her son and his friend how to get pregnant was interesting—she lets her son ejaculate inside, but won't even allow penetration from his friend. I like that this series doesn't follow a rigid template. The ending where she can't forget her son's cock and attacks him works well, especially with the preceding scene where she's rejected by her husband, which justifies the situation. You can still feel that sliver of maternal instinct remaining. The only downside is that Eriko's presence was so strong that it overshadowed Sayo Arimoto, who played the daughter and only appeared in the first half. I was looking forward to seeing Sayo, so it felt like a waste.
Eriko Miura's acting is always reliable. She played the loving mother perfectly. She doesn't just give sex ed to her son and daughter, but gets carried away and gives a little 'lesson' to her son's friend too. By the end, it wasn't about education anymore; it felt so real seeing her find happiness as a woman in her son's arms.
This work is overflowing with Eriko Miura's charm. I've watched it many times. Unlike today, where 'internal ejaculation' is often faked, I'm grateful that works from that era can be watched with peace of mind.
