Katainaka ni Totsui de Kita Russia Musume to H Shimakuru Ohanashi is one of three hentai releases to come out during the final Friday of December. Oddly enough, all three of them made it onto this countdown. In fact, they’re the first three on this list.

Katainaka ni Totsui de Kita Russia Musume to H Shimakuru Ohanashi continues with the sexually frustrated wife, Alisa, living with her brother-in-law, Kenta. Kouta is still out of the picture as he attends an important business trip. In the meantime, Kenta has been peeping on Alisa during her late-night masturbation therapy. Realizing that Alisa is missing her husband’s touch, Kenta attempts to take advantage of the unassuming Alisa. Due to their cultural differences, Kenta teaches her unorthodox methods in order to bask in his perverted fantasies.

One positive note that Katainaka ni Totsui de Kita Russia Musume to H Shimakuru Ohanashi has going for itself, is it’s incredible masturbation scenes. Both episodes have given us some lengthy masturbation scenes of Alisa in provocative clothing. What really brings this episode out is the aforementioned revealing clothing that Alisa sports. Collaboration Works designed it so that each outfit Alisa wears becomes transparent, allowing us to see the full package. With each episode, the characters and story get even kookier, but we’ve come to accept that.

The number four spot goes to the first of two PoRO releases on this countdown. Oide yo! Shiritsu Yarimakuri Gakuen returns to our list once again with a heavy dose of anal play. PoRO has had a tremendous string of releases in 2017 and we hope that continues next year.

The fourth episode of Oide yo! Shiritsu Yarimakuri Gakuen returns with more of the peerless president, Mira Campbell and the prodigy, Kujo Shizuru. After the events of the third episode, Mira becomes curious about the effects of anal beads. Mira enters a private room in hopes that she will get some alone time to experiment with the beads, but lo and behold Yabuki walks in on her when she is literally balls deep in her toys. He shows interest in her experiment and wants to assist any way he can.

The theme for this episode of Oide yo! Shiritsu Yarimakuri Gakuen is anal sex. Nothing seems to be off limits when it comes to anal sex, including some jumbo sized beads. Most of the focus on the h-scenes is bead play and loosening themselves up for the main course. Yabuki even “skewers”, Kujo in an attempt to show up Mira and prove that Kujo is one step ahead of Mira, in terms of body preparation. Make no mistake; if you’re a fan of anal sex this episode cannot be missed. Heck, even if you aren’t an anal enthusiast, there are still enough lewd acts to please the average viewer.

It shouldn’t come as any shock to people that JK to Ero Konbini Tenchou has made our top 5 monthly hentai countdown once again. Every release for this series in 2017 has made our list, and quite honestly, I doubt that’s going to change going into 2018.

JK to Ero Konbini Tenchou very much follows in the previous episodes footsteps and picks up right after the previous episode. Yoshihiro finds himself humbled, on his knees ready to take any sort of punishment that his older sister, Mao, can come up with. It’s clear that Mao has always had control over her younger brother, even when they were younger. With Mao in the picture now, Yui and Shiori are going to have to find a way to eliminate their threats.

One of the more interesting additions to this episode of JK to Ero Konbini Tenchou was the flashbacks between the siblings. This properly conveyed the sibling’s history with each other. In doing so, it added more to this nutty story; which continues to get more and more outrageous by the episode. It’s slowly becoming one of our favorite PoRO series because it’s offered us six episodes (to this point), some stimulating scenarios and some of the best visuals to date from this hentai producer.

Coming in at number two is another T-Rex visual marvel, Kyonyuu Daikazoku Saimin. It was released on the first of December making it the earliest release on this countdown. Kyonyuu Daikazoku Saimin is the sequel to the single episode release, Kyonyuu Kazoku Saimin from 2014.

The sexual relations between stepson and mother have reached a fever pitch. It’s become abundantly clear that something unusual is going on in the Mamiya household. The neighbors have gathered around and gossiped about the indecent acts that they’ve heard. Nanae, one of the neighbors, builds up the nerve to visit Yuuichi and ask him if anything unusual is happening around the house. What Nanae doesn’t know, is Yuuichi has a Magic Penlight in his possession. It’s not long before Nanae falls prey to Yuuichi’s twisted device.

While it seems to be the norm for most hentai nowadays, we can’t help but point out how short Kyonyuu Daikazoku Saimin is. Clocking in at 16 minutes, it certainly leaves room for improvement. Apart from that, this episode was solid. It has tremendous breasts movements and detail. There’s an expansive cast of females which includes all three ladies from the previous series and several new ones to enjoy. Kyonyuu Daikazoku Saimin leaves you on a cliffhanger, but fortunately, this series is going to see more than one episode. The second episode drops next month.

We end the year off with Mary Jane’s Kime Koi! topping our monthly hentai chart. That seems fitting since we felt that Mary Jane was the best hentai producer of 2016 and now we’re ending 2017 with Mary Jane back on top, at least for this month.

The second release of Kime Koi! follows the lustful pair, Hajime and Megumi’s passionate encounters; thanks to Misa’s aphrodisiac. Misa’s pill was an obvious success for Hajime. Megumi and Hajime were inseparable. This causes Misa to become a little jealous of their situation. All Misa wanted was Hajime’s sexual attention too. She was done being the couple’s cupid. As Misa is about to leave the two alone, Megumi suggests that Misa should take the love drug. If she has true feelings for Hajime, the effects of the drug will guide her.

The second episode of Kime Koi! really took it up several notches. The first episode mainly focused on Megumi and Hajime. It ultimately left many fans disappointed when we didn’t get a threesome with Misa involved. That was rectified in the second episode, with plenty of threesome action to go around. The majority of the episode is the three going at it with each other. The positions are varied and the lust from the aphrodisiac is present. For us, it was nice to see both girls get the attention they deserve.
