You're on the forums for three such games: Corruption of Champions, Trials in Tainted Space and Corruption of Champions 2. Lilith's Throne is a similar game made by a different person, though its update cycle is rather slow and tends to get delayed a lot. All of them have everything listed here to varying degrees (except LT which doesn't have Bad Ends yet but they're planned for future content), mainly that BDSM/bondage is noticeably less common than other submissive options. Also be aware that CoC is quite rough around the edges (as the writers/devs had much less experience making games back then) and runs on the recently-deprecated Flash.
You might also enjoy at least half of the six paths in Dungeon of Lewdity (namely, the Bondage -> Public Use, Bondage -> Petplay and Mental -> Submissive paths). It doesn't contain 'proper' Bad Ends but there are quite a lot of endings depending on which path you're on and when you choose to leave the dungeon.
