Famous for popular harem hentai like Eroge! H mo Game mo Kaihatsu Zanmai, Tropical Kiss, and Mankitsu Happening, Collaboration Works have made themselves the hentai studio that made the 2010s an exciting decade for hentai. Tsugou no Yoi Sexfriend is their best work and should be the one to have all the accolades than the overhyped Eroge! H. It does help that you are working with the talented visual novel developer, Waffle, known for classics like Kyonyuu Fantasy, Maki-chan to Nou, and Mankitsu Happening. A match made in heaven.
When looking at the sex scenes, for the most part, they are very vanilla. Except for one involving lite BDSM, it still manages to carry its fun atmosphere without it being distracting. Ahegao galore in this hentai. So if you want something that has a cutesy personality yet has some hardcore slutty action, Sexfriend manages to balance these two elements relatively successfully.
As for the girls themselves, let's start with the weakest of the bunch, Aina Kamishima. Not to say she is terrible by any stretch; I like her a lot, but her scenes were not particularly as memorable or what I go back to fap away to. I like long-haired girls with glasses, so it is hard for me to pass her up as a useless thot. Ryouko Yanagi is all about the mole below the lip. For some reason, I always get so obsessed with a little detail like that on her. Her mature demeanor makes her the most adult of the bunch and adds a bit of oomph to the harem. Not to mention she's voiced by Mei Misonoo, who has the best MILF voice of any hentai seiyuu.
Makiko Endou, yet another mole girl! Except she is blonde, so she automatically gets a big bump above Ryouko for me. Her scene involving the main protagonist and Kotori with Makiko blindfolded was adorable with her ahegao face after her dick action. 2nd best would have to be Kotori-chan. This might be biased because I'm a massive sucker for overly moe girls that turn slutty during their sex scenes. It helps that her twin tail hairstyle boosts her cuteness and sexiness. Finally, my favorite is Misako-chan. I can see why some may not have her as their favorite because she does come across as your typical childhood friend who is a romantic interest. Yet, something about her caring nature for the protagonist and likable personality makes her even sexier. What more would want out of a cutie pie like her, her side ponytail, big boobs, and willingness to please her man?
Like I've said before, Tsugou no Yoi Sexfriend is the perfect hentai to relax. If you don't want to watch/fap to something too hardcore or heavy in its subject matter, this would be the perfect one to try out. Four episodes of harem hentai goodness get consistently better with each passing episode. Usually, that isn't the case with many hentai series, even highly produced ones to the level of Sexfriend. Hentai studios should take this hentai to heart for future generations if they want to create more quality content like this.
