Well i like the approach of her starting playful and her also having doubts and limitations about using him, but at the same time having this voice in the back of her head which wants her to really abuse him with no limit.

So for now i would also go with playful, but leaning more to abusive already than in the previous chapter.

Great story so far. I really like it when Women dominate men by using their natural bodily scents and tastes. I also like that the mother is still a bit conflicted about using him in all these dirty ways. Creates some suspension when she will finally not be able anymore to hold back.;P

Hope that it will gradually get more extreme though and not jump to the most extreme stuff immediately. Makes it somewhat more believable in my view.

Maybe let him get used to the smell and taste of her sweaty feet more first... let him maybe even lick clean her sweaty armpits (because she has forgot her deo and she claims its an emergency.;) ).

Oh and I like that he is not that unwilling. Meaning he gets turned on by this treatment. Imo that makes the story also more "real" in that sense that it helps the mother (and sister maybe) to overcome their limits since they just use him like he likes it anyway. :)

Another idea could be to introduce other females. Maybe e.g. a female psychiatrist the mother attends after using him as living dildo for the first time. Instead of getting her out of it she could strengthen her in her desires... and might even use him too (so she can properly judge how the mother must feel like. ;P )

Love the setting and the character portrayals. They feel so much more alive than what you read in most other stories here.

Also hoping our hero will manage to visit all one hundred prospects.;)

Btw hoping to see some dark elves or even somewhat civilized humanoid races like Orcs too.

Also maybe you can make some prospects Queens themselves , who haven´t married yet and are somewhat older than the young princesses we had so far? Would imho add some further diversity to the future "cast".

I really like the Asian woman dominates white guy setting. Maybe she could emphasize more that she sees white guys as way beneath her? Also hope she will stay "dirty" and make him worship more than just her feet in the future.;)

You may check some of the spelling though. There were a couple of very noticeable mistakes; e.g. "here" instead of "hear".

Oopps, forgot to rate it. 10 out of 10 of course. ;)

Good starts. Like the relationship dynamic if the characters and the focus on female body odors. ;P

Going forward I hope that the older sister gets influenced by the younger sister concerning how to treat the little one.:)

Doesn't have to be full sadist like another review said, but maybe have instances where she would observe him actually getting excited about certain humiliations and body odors. Maybe have him sniff dirty socks and panties of them while he thinks he is alone, and have her secretely watch.
So it wouldn't be one sided, but a progression from her and his side towards him becoming their somewhat willingly sex toy and fart sniffer. ;)

I really like the direction this is going. Hope Megan and Alexis will be successful in slowly convincing Ashley that our "lucky" hero is into smelling and tasting any kind of female body odour, and of course especially Ashley's. No matter how nasty.;P

One thing concerning the treatment of the MC. I wouldn't go the way of the Females torturing him in ways that could severely harm or kill him (like throwing him in the toilet or threatening to crush him under their feet). 
 I think it would be more powerful if they show that they care about keeping him "intact". So that they can keep him long term as nothing but a slave-toy, subjugated to worship their sweaty feet, armpits, butt cracks and pussies for many, many years to come. :)  
At least imho that is a way more humiliating and damning prospect to look forward to.
