definitely Bishoujo Mangekyou -Tsumi to Batsu no Shoujo- . they made toxic yuri straight. i have a thread on it too https://bsky.app/profile/nadianova.fi/post/3mawhtjeq4k2g outside of that i really really really like EXTRAVAGANZA ~Mushi Mederu Shoujo~ and its sequel despite the pacing issues that come from its ridiculous moon logic choice mazes and how 100%ing means you have to spend like half of the games runtime just listening rape moan sfx on repeat which does get a bit old when i just wanted to see all the plot there was but also i didnt want to skip through the scenes either cause they were fine just that there was too many. in one of the yuri routes a bug induced futa dick wraps around the protagonist cock and gives her a cockjob. its great
