This whole conversation just had me picture the scenario in my admittedly fucked up mind.
MC : "Hey, sorta-Dad. I'm going to go fuck not-Mom since she's horny and you kinda don't have a dick."
Athagan : "Oh thank the Goddess, she's been bugging me non-stop for oral lately. I literally can't feel my tongue. Be sure to cum inside, I think another kid would make her really happy."
MC : "Uh, ok, can she still have them?"
Athagan : "Eh, no idea, but she's a priestess that worships a sex and fertility Goddess so I wouldn't be surprised."
MC : "Cool, off I go then. Uh...wanna watch?"
Athagan : "No that's ok son. Ever since the demons cut off, burned, and then ate my cock and balls in front of me I haven't really felt that interested in sex."
MC : "..."
