This is a pretty nice hypnosis cheating story if you're interested in those or a fan of the artist Polinky then you'll probably like this.

This doujin pretty long at 97 pages comes in 3 distinct parts. The first part is just the standard jealous younger bro hypnotizes the wife and has lovey dovey sex with her. This first chapter is good but the little bro ends up unsatisfied as the housewife he's banging is still in love with and loyal to her husband. Getting to bang her using hypnosis is not good enough, little bro seeks a more total victory so in the subsequent parts he reworks her hypnosis to make her more resistant to the idea of cheating on her husband and then he has to use the power of the dick to mindbreak her the old fashioned way.

There's also some pretty good cosplay in this doujin. I especially love the parts where the woman, who is an older housewife, does her hair in a ponytail and wears a high school uniform. Super erotic school uniform sex exactly to the preferences of the little brother character. So good.
