Huh I'm sceptical on how that's gonna work, all the set up so far seems to be for her to be a secondary LI. Maybe a feminization/dom/cuckold route with James but can't see the connection with the mom.
But I'm not gonna judge it until it comes out. The content so far has been great, so it'll probably be great regardless of my doubts
There is a huge range of possiblity, honestly. However, we already got a hint that she is a slut, since she is one of the 4 girls who appears on the Halloween special party. I imagine that there is a possibility of she going bisexual and fuck Lucy, maybe even ending up pimpin her. She already talked previously that she has to spend "extra time" sometimes with the director ( considering her presence on the Halloween special, i wouldn't doubt that she is fucking him ) , which ends up ruining james date with her, she may start to blackmailing James and using him to gain power over James. There is also the possiblity of she being a source of corruption towards James in the same way Rom corrupted Lucy, and many more. We already have hints to notice that she ain't the "vanilla" trope, she even started to send James nudes even tho she barely knew him. I am pretty excited for what he's gonna come up with. Most MC's problem starts when a person meets his mom, and Anna is one of the few characters that hasn't done this yet.
James also has proven that him himself inst capable of coming up with the idea of fucking his mom, external events or people needs to be involved so they influence him to do it, Anna may do the job. Honestly i want to see some lesbian scenes of her with the mom, would be interesting. The worrying about the mom is valid, but there is 3 more women on the story, focusing only on the mom may take out the special part of her on the story, becoming more "the pattern" than "the special one".
