You mean with the mc being a trap? Those are quite rare, especially english-language versions.
There is
School Idol ♂ Itoshi No Qtie Cool and that's it. Aside from that there is
Trap Shrine and its sequels, also
Josou Sanmyaku and
Female Strait. Basically anything by Nounai Kanojo.
Though those all have at first reluctant MCs, who tend to need a bit of convincing before they leave the straight and narrow, so to speak. Also the MCs in those games aren't traps.
There is also
Netorare Otoko no Ko where the "MC" can become a trap, though that one isn't exactly my favorite. Which is less because of the NTR and more because of all the baby-talk.
(Male pregnancy always makes me think about Dogma's Golgothan
)
But that's basically it for english-translated eroges with traps. There are more which haven't been translated. But unless you know Japanese or are prepared to mess around with programs like Sugoi, you're shit out of luck.
There are also a couple of non-eroge trap-games here on the site, in varying degrees of quality. Those you can find by including the trap and gay tags on the "latest updates" page.
Sadly it's a fetish not that many people are into, so there aren't many devs who cater to this niche.
Which is why I'm so disappointed about how this game turned out.
Anyway sorry for the long text, just try the ones I've linked above and remember to stay hydrated.
