NTR a Girlfriend Ver.0.355 by TMD4M - Adult Sex Game

Content Warning: This game contains sexual content, including themes of Netorare (NTR). All characters are 18+. An NTR ending is avoidable — the game is designed with both vanilla and NTR routes in mind, and vanilla is not an afterthought.
You play as Kazuya, a struggling college student torn between lies to his friends and family and his deepening feelings for Chizuru, a rental girlfriend chasing her dream of becoming an actress. When her charismatic acting partner Umi helps her land a role, is it out of kindness… or something else?
Meanwhile, another girl steps forward, determined to win Kazuya's heart.
As Kazuya, you'll spend time with the girls on dates, raise affection, and make choices that change the ending.​
