I agree that it SHOULD be part of a progression if realism is what is being pursued because for many women, going down on her is kind of a cheat code to ensure she will have at least one orgasm (assuming it's done well), or so I've heardCunnilingus scenes being so entirely lacking in so many games is so weird. I've yet to meet or hear of a woman (that wasn't asexual or disinterested in sex, of course) that wasn't into it or even needed it to help get an orgasm. It SHOULD be a part of a lot of games, if only to pad out character content.
I think the fact that Meredith is MC's Mom does add a special significance to this kind of scene, given the context and I think it's an important step for both of them. You all are going to have to "eat your vegetables" if you want progress with Meredith.
For the record, I don't see a reason to have a cunnilingus scene for any of the other characters aside from Meredith.
There is kind of a blunt truth to this. Many guys DO like going down on their actual, real-life partner, but doing so for a fictional cartoon character, even for one they may have grown attached to like Meredith could be like... doing the dishes. I will try to make it interesting and/or fulfilling and maybe even make a mini game or puzzle out of it. At the end of it, MC will unlock Kissing III, which should be exciting, right?Most men aren't actually that interested in doing this, is the simple reality. So in porn games, which are fantasy, people see little reason to add these scenes.
BTW, Most women don't enjoy giving blowjobs outside of the first time or two when it's new, exciting, and/or naughty.
