Also posted on r/HentaiSource, but I also wanted to post it here just in case. I’m looking for a doujin I read before where basically, a girl gets a voucher for a massage and when she goes, she finds out that the masseuses are three women. They make her put on a swimsuit and give her some sensory depravation stuff (eyemask, headphones, incense) so that the girl doesn’t know what they’re talking about while they massage her. In actuality, the masseuses want to make her body super sensitive, so they oil her up and massage her sex parts while gaslighting her into thinking that this is how a massage is supposed to be. There’s also no guys in this one, girls only. I remember finding it on a website that wasn’t nhentai, but I can’t find the link again. It was also in three separate parts.
