you could try: rogue-like, you have full control of the sex scene(so long the character is ok with doing it), so you could do ass to mouth for example, there is some cumplay, as the game has an addiction system, and depending on how severe they are, you could even charge them for a dose of your cum.
ring of lust has alot of blowjobs, with some minor cum addiction.
high tide harbor has a character with cum play.
Eroge! H mo Game mo Kaihatsu Zanmai. one of the characters has some cumplay as you progress her route.
lab rats has some bukkake.
take over has a scene involving cumplay(mostly cum on coffee)
superpowered has some minor corruption events.
something unlimited has a minor scene involving cum on oreos, and you can get BJs or DTs from most women.
aurelia, most female characters have blowjobs with cum swallow.
park after dark, one of the characters has sleeping blowjob. the others have bjs.
four elements trainer book 4(slave route) has a shake you can "add milk".
euphoria has a character focused on cum drinking(but that game is pretty brutal).
from this list, i think the first 4 are closer to what you are looking for, but there are others out there. also all are male MCs.
