At the beginning of our list, we come across a beautiful purple-haired girl by the name of Rio Yakumo. She and her sister Miyu, get put into a sticky situation to say the least. Their grandfather heads a Yakuza group. He suddenly falls ill while another group brings a potential takeover to him. In order for Yakumo family to thrive, they will need to make a deal with a rival group for their support; however, it’s going to cost them a female or two. Rio being the older of the two sisters sneaks out at night and heads to the rival group's headquarters. She gets taken advantage of by the leader of the group and is made to play several sick games in order to satisfy the rest of them. Miyu notices that her sister is missing and goes out to look for her. It’s not long before they seize their ultimate prize, which is getting both girls at once. Rio tries to protect her younger sibling but it’s no use, they both succumb to the lust and desire of their rival group. The sisters get used and abused, but one of the redeeming moments comes at the end of the anime. Watch for yourself and see!

Yes, you read that right, Yamato. Although females are more commonly used as slaves than males in hentai, this is one example where the male is used for two female’s desires. The battle between angels and demons has reached a pinnacle of their feud and in order to finish this competition, they’re going to have to try and win Yamato’s heart, by any means necessary. An angel named Sera and a demon named Firika contend to see what race ultimately comes out on top. The episodes are basically split between Firika getting most of the action in the first episode and then Sera getting the lion's share in the second. The series starts off with the fiery Firika demanding that Yamato signs a suspicious looking contract. His refusal to do so led her to think outside the box. She quickly realized he’s going to be harder to tame than she imagined. Sera shows up and although she’s less demanding, she can’t seem to get him to decide, even after all the joy she’s handed out. Jealousy eventually breaks out between the girls and they take on the challenge in the same room. Yamato is being used as a pawn between two ancient races. We won’t spoil the ending, but my goodness, what a tough decision he has to make.

This next selection brings us a lot of NTR (netorare) from a couple of cute females. Reiko, the president of the school council and vice president, Shintaro are tasked with looking over preparations for the school festival. During the festival, they are asked to try an unknown drink. They oblige and not long after they start to feel the effects of the beverages. Reiko decides to take Shintaro to a classroom and use him for sexual release. What she doesn’t realize initially is that the person that is taking out their lust on her is not her boyfriend. From here you can kind of guess where this leads to. The unknown rapist takes full advantage of Reiko in the dark classroom and then proceeds to record the immoral act so she will have to do what he says. It’s then that another student council member, Misaki is introduced into the story as Shintaro is unaware of Reiko’s whereabouts. Needless to say, both girls end up becoming sex slaves to the initial rapist. The h-scenes take place in several different public areas. The humiliation of both females and Shintaro reaches an all-time high while in a classroom when both girls are made to strip down and have sex with the deviant. Shintaro is excused and made to keep watch outside in the hall.

For our number seven pick, we go with two females who try and keep troublemakers in line at their school but only realize that it’s more of a taxing job than they thought. Rina and Kumi take center stage in this group setting, but there is an impressive male character named Junzo, who proves to be a hotter commodity than the girls initially thought. He even saves Kumi from being abused in the men’s bathroom from a couple of her ex-boyfriend's acquaintances. After that act of heroism, Junzo receives a reward from Kumi in the men’s bathroom. Shortly after, Kumi finds herself in an abandoned warehouse where the majority of this anime takes place. A group of sexual predators all pounce on Kumi and she does her best to fight them off, but to no avail. She even has her escape thwarted and is punished further as a result. Rina receives a phone call from the attacker telling Rina to meet them at the warehouse. Naturally, when Rina arrives she is ordered to give them sexual favors. If she is able to do that they will let them leave, but as we know in hentai, that’s generally not the case. They turn both girls into sex slaves as Rina is forced to give out many blowjobs and do other sexual acts.

The premise of this hentai is that a couple of very attractive girls by the name of Ibuki Kurata and Akira Miyauchi are tricked into thinking that they’ve won a free trip to a summer resort. Sure enough, once they reach their destination things start to plummet in a hurry. In addition to the girls being deceived they now have to struggle with the fact that they’re helpless and locked up by a group of upper-class students. Their intention is to train them to become their personal sex slaves. The anime quickly establishes the central plot with a flashback on how they got locked up at the summer resort. From there the girls are treated like a piece of meat with the guys declaring who to initiate first. Akira is the first one selected due to her feisty nature. In a sheer act of malice, they make Akira pleasure the guy she hates the most out of the group. It didn’t even take an entire episode before we see Akira submit to the male's desires. It wasn’t her lack of trying; they were just persistent to the highest degree. This anime does a great job at showcasing the female’s struggles and ultimate obedience.

We’ve approached the halfway point of the countdown and it’s only fitting that we come to Akina Shiido in Menkui! She is an example of becoming a sex slave by her own willingness to please her childhood friend. Despite what this list has shown you, there are hentai out there that showcase slaves in a more positive light. The reasoning for Akina becoming this slave for Masaru was because she wanted to get noticed by him and every advance prior was met with rejection. How he ignored her is beyond us! This anime brings a whole new dynamic to this list that we haven’t presented to you folks yet. Masaru has an unhealthy obsession with maids. Akina has a crush on him and finally sees the big picture. If she dresses as a maid for him, there is no way he will turn her down. Akina progresses along nicely becoming his maid/sex slave. She isn’t reluctant to please him at any given moment, as giving him a blowjob outside the school is proof of that. What makes this hentai unique is that his blowup doll transforms into a human. The competition between the two girls turns into ecstasy. It’s a rewarding experience when we see Akina’s motivation levels soar.

Our next pick is a science fiction space adventure involving a space criminal by the name of Donny Bogan. He happens to be captaining a ship representing the Neo Terrors. Donny has been building resentment and plotting a plan to get back at New Solar commander Lieri Bishop and her aide Naomi Evans for sabotaging his mission four years ago. His plan is to kidnap them at the Titan Space Station and then bring them aboard his ship so he can brainwash them and use them for his sexual desires. Naomi is an up-and-coming Major part of the New Solars faction. She has short purple hair and a striking set of red eyes, which matches her personality. Naomi is seen as a hotheaded individual who hates Neo Terrors. Early in the series she is shown to have exceptional fighting skills and is able to fend off numerous enemies. Once plans go awry, the girls get experimented on, which then brainwashes them and they become the Neo Terrors “Comfort Officers”; in other words sex slaves. Naomi and Lieri are in charge of keeping the morale up on the ship by any means necessary, including being tortured if the rest of the crew calls for it. The girls go through a grueling seven-day sex party all for the delight of Donny Bogan.

Inching closer and closer to the end of this list, we bring you another sex slave, Atsuko Takagi. She recently moved to a new town in order to become a teacher at a high school. Along with her younger sister Yui and her father, they plan to work off any debt that should arise. Atsuko and Yui have unwillingly become involved in a massive sex storm that they can’t escape from. A town full of watchful eyes and deceit fall over Atsuko and it’s much too late to back out now. Atsuko is a bright teacher who only wanted to further her life by taking a job at a high school. It’s not long before her life becomes a living hell due to some misunderstandings and malevolence. When candid photos of Atsuko get posted in her classroom she becomes blackmailed. It’s then when she becomes one of her student’s sex slaves and is told to do everything and anything for him; otherwise, she and the rest of her family will fall on hard times. It starts out with Atsuko being the main target of much abuse but then it proceeds to add Yui, which further escalates as they both become slaves for various people in town.

This next hentai is a sad portrayal of a female who is issued with only a number for her name at her school. “No. 3” is what she is referred to as, at a male dominated school. All the other females are tied up and used as sex slaves to further stimulate the males so they will commit fewer crimes. There is one guy in the school named Nakagawa, who feeds her and treats her like a normal human being. It’s then that he finds out her real name, Mitsuko. Out of all the characters presented to you on this list, we feel that Mitsuko is probably the most endearing character. You truly feel sorry for her and the feelings that this hentai generates is truly a rarity in this genre. She is more than just a sex slave and it radiates through the screen. It’s telling when despite knowing little about Mitsuko you can truly sense her disconnect. She is used for sexual favors and is quickly put in her place if she even as much as hesitates to please. Nakagawa is the only “normal” guy in the school. He even gave her clothes, since all the slaves just walk around naked all the time. It’s a heartfelt hentai that you should check out for different reasons.

Here we are, our number one slave in hentai goes to Yayoi Nijihara, a widow who was married to a leader of a biker gang. Five years has passed since Hiro’s brother passed away. Since the accident Hiro has been living with his brother’s widow, Yayoi. Hiro has always liked Yayoi and now that she is single once again, he can’t help but express himself. Has enough time passed for Yayoi to heal and will she reciprocate those feelings from Hiro? Well, the short answer to that question is yes. Yayoi is a busty brown-haired gem, who seemed to be a prize that many peers couldn’t attain. Yayoi had always noticed that Hiro took a liking to her and she finally gave into him one night. After that night she became fixated on him. The story took a turn for the worse when a former member of the biker group showed up and blackmailed Yayoi into having sex with him. That was the ultimate goal for this sexual predator. From then on he broke her physically and mentally. It got to a point where the deviant was the only one who could satisfy her. Be sure to check out the second part of this series that just came out in July.
