Here are my favorite picks for anime like Netsuzou Trap -NTR-. Keep in mind the list is in no particular order. Enjoy!
Scum’s Wish
Hanabi Yasuraoka and Mugi Awaya are the perfect couples for the outside world. But in reality, they share the same secret pain: they are both in love with other people they cannot be with.
Hanabi has loved her childhood friend and neighbor Narumi Kanai for as long as she can remember, so she is elated to discover that he is her new homeroom teacher. However, Narumi is soon noticed by the music teacher, Akane Minagawa, and a relationship begins to blossom between them, much to Hanabi’s dismay.
Citrus
During the summer of her first year of high school, Yuzu Aihara’s mother remarried, forcing her to transfer to a new school. To a fashionable socialite like Yuzu, this inconvenient event is just another opportunity to make new friends, fall in love, and finally experience a first kiss. Unfortunately, Yuzu’s dreams and style do not conform with her new ultrastrict, all-girls school, filled with obedient shut-ins and overachieving grade-skippers. Her gaudy appearance manages to grab the attention of Mei Aihara, the beautiful and imposing student council president. She immediately proceeds to caress Yuzu’s body to confiscate her cellphone sensually.
Thoroughly exhausted from her first day, Yuzu arrives home and discovers a shocking truth—Mei is her new step-sister! Yuzu initially tries to be friendly with her, but Mei’s cold shoulder routine forces Yuzu to begin teasing her. But before Yuzu can finish her sentence, Mei forces her to the ground and kisses her, with Yuzu desperately trying to break free. Once done, Mei storms out of the room, leaving Yuzu to ponder the true nature of her first kiss and the secrets behind the tortured expression in the eyes of her new sister.

A sequel to Aki-Sora under a new name.
Love and Lies
In a futuristic society, Japan has implemented a complex system called “The Red Threads of Science” to encourage successful marriages and combat increasingly low birth rates. Based on a compatibility calculation, the government assigns young people at the age of 16 marriage partners, with severe repercussions awaiting those who disobey the arrangement. For Yukari Nejima, a teen that considers himself average in every way, this system might be his best shot at living a fulfilling life.
However, spurred by his infatuation for his classmate and long-time crush, Misaki Takasaki, Yukari defies the system and confesses his love. After some initial reluctance, Misaki reciprocates his feelings in a moment of passion. Unfortunately, before the two can further their relationship, Yukari receives his marriage notice. He is then thrown into a confusing web of love and lies when his less-than-thrilled assigned partner, Ririna Sanada, becomes fascinated with his illicit romance.
Sakura Trick
Love is in the air when the story of Sakura Trick begins. Haruka Takayama and Yuu Sonoda were best friends in middle school and are now attending Misato West High School together. They are assigned to the same class in their first year but are given seats on opposite sides of the room! If that wasn’t enough, it is announced at the entrance ceremony that the school will be closed in three years. This doesn’t bother either of them, as they still plan on having lots of fun together during their high school years.
However, Haruka gets jealous of Yuu making new friends, so the two decide to deepen their bond. “Let’s do something we’d never do with other girls,” Yuu says, and they share a kiss in a vacant classroom after school one day. After that, one kiss leads to many kisses. The two begin to realize that the relationship they share has changed completely. But what will happen to their relationship once a disapproving older sister begins to suspect something is going on between them?
My Marriage Partner is My Student, a Cocky Troublemaker
Teacher Nano Saikawa hasn’t given much thought to marriage, but her father’s friend wants her to have a marriage interview with his son, Souichirou Takamiya.

However, when she removes his glasses, she discovers he is not Souichirou; he is one of her problem students, Souji Kuga! Things quickly heat up between them, and the two wind up in bed together.
Souji’s explanation is watertight: when he realized his brother was to be Nano’s intended, Souji posed as him to be with her. And what’s more, he is confident that his family will approve of their marriage. However, an illicit relationship with a student is the last thing Nano wants. But will she be able to resist his charms, especially when her body begins to ache for his?
