I really enjoy the whole lost a bet and has to pay with her body scenario. It would actually be nice to see the negotiations as well. I mean, at some point he told her, "Last time you wouldn't let me eat you out. So I want that this time." And I wonder what she wanted him to do if she won? (Probably leave her alone.)
I'm still really enjoying the slow escalation and the resistance Akiko-san continues to put up. The explanation from her research resonates with me (at least in porn world, in the real world if a woman said no, I'd scratch her off my list and leave her be). I really enjoy sadistic / femdom Akiko. It'd be funny if she somehow ended up servicing / abusing all 3 of the guys in the house, all the while wondering how this happened. I imagine that would be short lived though. Ren-san is sharp as hell and the first time she found out about it, no doubt she'd force Akiko into a ganbang where Akiko was the submissive one.
Meanwhile, I wonder what her relationship is with the other two guys. It doesn't seem like she's done anything with either of them. Though that's kind of hard to believe considering how horny the dad is. I'm also not sure she could dominate him (though he might be happy to play along once or twice). I don't have a sense for the younger brother as he's only shown up very briefly. I suspect she could dominate him easily.
Couple interesting bits of info that comes from the character sketch. Akiko is childhood friends with Yuriko (the father's second wife). She's never been married or had kids and only dated one person. She also doesn't save her money (I wonder what she spends it on).
Speaking of the sketch, Sensei seems to have refined everyone's looks lately and is sporting a slightly different art style. I like it, but I'm also a little worried as Akiko is starting to look too young and cute for my taste. I really like her as a cranky lesbian milf who is only reluctantly letting herself be used as a cum-dump. Ah, but it's kind of nice to see her cute side too and how she's slowly moving towards enjoying dominating Takayuki. Anyway, I'm looking forward to whatever Sensei writes next. In the meantime, I'll probably translate the short stories for the other women as their own release.
As a note, I moved around some of Akiko's stories to try an get a coherent longer narrative. It fits pretty well.
