Towa(omega) is deeply in debt thanks to his ex boyfriend running out on him. That's when he meets Aiji(omega) and Seiji(alpha), twins who claim to both be marked omegas, and they offer to buy him for the night. It goes so well that Towa agrees to a slave contract where they pay off his loan and treat him as their dog. Even when Towa realizes that Seiji is really the alpha who marked Aiji, Towa doesn't mind and things seem to be going well, but as Towa starts to be able to tell them apart and encourages Seiji to differentiate from his brother, it starts to upset the careful balance between them. This one is a little dark, but I think it shows interesting character growth for the twins by the end. Trigger warning: sex work, slave contract, rape, abuse.

Ai Subeki Sadist

Complete | hakoishi tammy | 2000 released

Jun-kun gets called out by the older, working man Fumitaka after putting on a BDSM show at his workplace. Supposed "Super-M" Fumitaka asks Jun to be his queen, and Jun reluctantly agrees, but it's not so straightforward as Jun has an unhealthy relationship between himself and sex, and Fumitaka has his own sadistic side that he keeps hidden from Jun. Further complications arise when Jun's brother and the source of his trauma appears, causing him to confront his past. Trigger warnings: S&M, bondage, incest (not blood related), non-con.

Kanata always feels the pressure of being a big brother to his brother Keita, so he lets off steam by working in a "little brother" style sex shop where men spoil him. But when Keita finds out, it prompts the two to finally talk to each other and realize they've both been unfairly judging the other all along, reconciling. Only now that they're closer than ever, Keita has realized his feelings for his brother go deeper than normal familial relationships. Trigger warnings: sex work, attempted rape, incest.

Why Don't You Lift Up That Skirt And Show Me Yours, Sister?

Complete | Sakuchiru,Karine,Mai murasaki | 2019 released

Loretta and Alto are siblings not related by blood who have never gotten along due to Loretta's intense tsundere nature that makes it impossible to say what she means. But Alto recently had a one night stand with a mystery woman that he's desperate to track down, and Loretta has a secret: it was her all along. She's always loved her brother, she just doesn't know how to express it! It's pretty predictable stuff but not terrible. No explicit scenes, btw. Trigger warning: mild incest (siblings by adoption)

Soukyoku (MEGU Iroha)

Complete | MEGU Iroha | 2015 released

Ikurou and Akaya are twin brothers who couldn't be more different as Ikurou excels in school and Akaya messes around. But in reality, Akaya is in love with his brother, and not all is as it seems. Ikurou urges Akaya to try harder in school and in return he'll grant him a wish, despite the fact that Ikurou's been terrified of Akaya ever since Akaya came onto him in middle school. But when Ikurou succeeds and demands sex in return, the relationship spirals out of control. Not my favorite, nor did it make the most sense to me. Trigger warnings: incest, rape.

Nanadome No Gomenne

Complete | kojima lalako | 2000 released

Satoru loves his younger brother, Tooru, but Tooru has a stutter that has caused him to become a recluse. Even though Tooru sleeps with Satoru and seems to love him, when Satoru suggests they move out together, Tooru refuses. But when Satoru finds out it's because of their mother's abuse, he finally snaps. I'd say it's at interesting read, but upsetting and definitely not for everyone. Trigger warnings: incest, abuse, murder.

5 Seconds

Complete | Sachimo | 2000 released

Ch.1-2, 6.5 - 5 Seconds - Hayato has special eyes that have been passed down in his family. For him, this means that when he meets eyes with someone for five seconds he can copy their "sensuality," so he uses his friends to help him jerk off. The one person he won't use is his childhood friend, Tsukasa, who he's tried to avoid since he realized his ability, but Tsukasa is too sharp not to notice, and when Hayato accidentally copies some eyes he shouldn't have and goes into heat, only Tsukasa can help him. A kind of random and unexpected setup, but I liked the characters well enough. Trigger warning: dubcon(heat). Ch.3 - The Way to Nurture Love - Keiichirou is a normal working man who got dragged to a gay bar and told to pick his type, so he randomly pointed to a worker, but when they turned around he saw it was actually his long lost twin brother, Yuuichirou. Yuu seems to be living life as a woman now, and Kei isn't sure he approves, but he can't help but worry, so he invites Yuu to live with him. But the longer they live together, the more the feelings from their past that forced Yuu to leave seem to reemerge. I liked it, but it is an incest story, so don't read if that's not your thing. Note: I don't think Yuu identifies as a woman, so if you're looking for trans characters, he won't really fit the bill. Trigger warnings: incest, transphobia(?). Ch.4 - Too - An unnamed protagonist (Nameless-kun) lives an ordinary college life, except for the fact that he has a stalker following him every day, buying and wearing all the same clothes as him, and putting not-so-secret cameras in his apartment, which is especially weird since he's a nobody and his stalker, Kudou, is quite popular. Nameless-kun doesn't see it as causing any harm though, so he lets it go until one day Kudou seems to stop dressing like him, causing Nameless-kun to wonder if his affections have changed, and that's when he realizes just how much he's been watching Kudou in turn. I'm not really into stalker romances, but this one was fine for what it was. Trigger warning: stalking. Ch.5 - Itai no, Itai no - Rei spends every day at high school breaking up fights between his childhood friends, Takuma, and Shinobu, who are at each other's throats over everything but insist on spending time together because of Rei. But Rei knows that secretly, the two are in a physical relationship fueled by their shared masochism. Rei has trauma to do with pain that has caused him to develop a masochistic streak too, so he wants in on this. Not my thing. Trigger warnings: masochism, suicide, voyuerism, violence, violent sex. Ch.6 - Mushuusei no Ohisama - Aki and Asahi were friends in high school when Asahi said he'd become the best actor ever and Aki promised to be the one to shoot it on film. Now, years later, Asahi seems to have given up on his dream and only works in the porn industry, but Aki is still determined to capture the best of him. But when they fight, Aki decides to rape Asahi on camera to show him all the faces he hasn't seen yet. Or something. I wasn't really paying attention because I don't like rape stories. Trigger warnings: sex work, rape.
