If you choose Olga, you have to swallow your own semen.
I hope this forced sperm swallowing incident is limited to Olga; it's quite disgusting.
Hopefully, that part of her sex scenes will be completely removed in the next updates, or at least made completely avoidable, since it contradicts the whole point of MC's part played in them turning him into the exact opposite of what she said she wants in a man.
Olga's fine asf, and she knows it, male attention isn't something she's in dire need of, but as it's usually the case IRL too, she don't fuck with desperate simps or cucks.
Based on her own admission, she wants a manly man to put her in her place in bed and protect her outside of it... this is the part where the MC comes in and does his MC thing. Don't know what the dev was thinking when he made that disgusting beta shit unavoidable, but it should be removed or made available only if the player wants to see it.
to be clear as a monogamy player that doesn't like to be with multiple women and like to save myself for one girl
If I'm not with a girl or I reject her, she's free to find love with whoever makes her happy
I'm in love with the sister in this game, so it bothers me seeing her with anybody else besides me, regardless of gender
I don't share the woman I love with anyone, so I'm hoping that I can make her choose between me and her girlfriend
Fair enough, but you probably missed the part where the MC just
pulled a Houdini, abandoned and cut off all contact with her for 20 long years (!!) claiming she became too controlling and possessive (where have we heard this bs excuse IRL, I wonder

) simply bcz she wanted him to try his luck at becoming a businessman and he considered being shot at in the military was the better option.
Motherfucker's lucky she still talking to him, wanting something even remotely romantic with her should be out of the question, but on the plus side, it seems like she trying to get back with him, considering her suggestive remarks and the way she dresses on some occasions in the story.
On an even bigger plus, her current lover, Velina, didn't seem too bothered by the fact that the MC snuck a peek at her huge titties in her office, so maybe a future threesome or a throuple is on the table for the him and these two.
In any case, he needs to earn his sister's forgiveness first before demanding anything for the exact reason I mentioned above. Whether Irina will be available as a solo LI or not remains to be seen in the next updates.
Keeping my fingers crossed she will, but Velina coming as a sweet 1+1 bonus doesn't sound like a bad deal to me.
