Hello, I come with a few more recommendations. What I generally look for in a game isn't one that's 100% anal since that's incredibly rare, but rather games where the game lets me choose to do only the anal scenes, and in the best case, acknowledges I've been doing so with either extra dialogue or specific endings.
With that in mind, here's a few. Forgive me if some have been mentioned before.
Ambrosia: You play as a priestess. Recommend saving often so you don't get thrown into a regular sex scene. There's a special ending if you avoid regular sex but have other like anal.
Rai-Oh-Gar: You play as the female pilot of a giant robot. In-between missions, you can roam around the city and engage in various sex scenes. One of the characters you can interact is anal only, and there's an ending by finishing all his scenes.
Wings of Roldea: This is more of an action game. You have a mechanic where you have a barrier that protects your virginity. As long as you keep it up, every sex scene becomes an anal one. Don't really remember if there's a special ending for it, it's been a while since I played it.
Virgin's Protection Magic: You play as an apprentice witch. One spell you learn is the Virgin's Protection, which while active prevents the MC from losing their virginity, and turns most sex scenes into anal ones.
Beauty and the Thug: Girl who goes on her own to the city. During each night, you get the option to train specific fetishes on the MC, one of which is anal. Based on the fetishes you trained each night, the scenes available during the day change.
