Yuki instantly transforms the moment a dick is inserted. This is the 17th installment in the series about a 30-year-old virgin brother-in-law, and Yuki Takeuchi meets a dick that fits her perfectly. The unemployed brother-in-law Yuichi comes to live with her, and to help him regain confidence after failing to find a new job, Takeuchi decides to take his virginity—a familiar setup unchanged since the first installment.
At first, Takeuchi hesitantly shows her breasts and pussy, but once penetrated, the compatibility is so perfect that she immediately cums from the dick, and when Yuichi tries to pull out, she says, "Don't pull out! Stay like that," allowing a creampie. Then Takeuchi wants more and actively pursues Yuichi.
Afterward, even when having sex with her husband, her mind is elsewhere, and she can only think about Yuichi's dick. When she hears her husband is going on a business trip, she can't hide her joy and gazes at Yuichi's crotch with desire. She tells Yuichi, who is doing well in his job search, "You should gain more experience," and progresses from deep kissing to blowjobs and anal licking. Using her proud techniques, she fully enjoys the perfectly compatible dick and delights in being penetrated.
Since her husband is coming home, Takeuchi asks, "Let's do it one last time!" and the once-virgin Yuichi has grown, leaving Takeuchi satisfied. There's a scene where Takeuchi gives a titjob in the shower, but it's a bit disappointing that it only looks like a handjob with her breasts.
It seems Yuki Takeuchi has filmed her retirement work this month, which is a shame, but releases should continue until around February next year. On the same release date, from the same director, I'd like to see her indulging in a perfectly compatible dick in "Father-in-Law with Erectile Dysfunction" and "Housewife with Big Ass Maid," as well as the NTR plot in "Your Wife Was the Best," and her role as a high-class soap lady in "Two People Perfectly Compatible in Body and Soul."
This series is director Natsu Kashū's masterpiece, featuring women who encounter perfectly compatible dicks and transform into erotic beings. For potential next-generation aces like Iyo Shinohara, Yuuka Niizuma, Kanau Yuki, Ichika, Nanami Mihiki, and Mio Kuon, the virgin brother-in-law would want to ask to be inserted, so I hope the series continues.
