Riko and Shuka, two otaku girls who met for the first time, hit it off instantly. With G-cup breasts and a giant vibrator, their 'casual' fun turns into a full-blown lesbian session that leaves them trembling.










Since others have already covered the actress details, I'll skip that. The first chapter starts with the two of them chatting, which felt like it took up too much screen time. Even after that, there were scenes of them showing off and stimulating each other's breasts and genitals, but Riko Sato's (now Umi Natsukawa) comedic personality kept peeking through, which killed the mood—a bit disappointing. Also, personally, the vibration noise from adult toys is distracting, so overusing them is a negative for me; fellow fans, take note. The final chapter was good. If I had to nitpick, I wish they had put the sports bra back on before starting that scene.
I bought this on sale without any expectations, and it turned out to be a surprise hit. First off, Shuka-san has a great figure and is cute. She has a look that appeals to everyone. Sato-san's face is borderline, but her body is so amazing that you don't even notice it; her way of speaking and gestures show such humanity and inner charm. She's the type I'd want as a girlfriend or wife. Her lesbian acting isn't exactly polished, but you can tell she's giving it her all. That said, the final nude scene on the bed was truly seductive, with an intensity and eroticism that rivaled any veteran actress.
*She's not an actress who's really good at being a lesbian. It's great to play while groping and discovering things.
The content starts with self-introductions and mundane chatter, then some fooling around, playing with toys, and ends with scissoring. It’s strictly softcore, so it’s not exactly 'convulsing' like the title suggests, though there is some trembling. There’s no moaning over double-ended dildos or vibrators; it feels more like a secret experiment between girls. Shuri-chan's (Riina Aizawa) hip movements during the scissoring were erotic, even if it was only shown for a bit.
The subtle distance between the two, evident in their overly realistic, awkward conversations and movements, creates a strange sense of eroticism in their lesbian scenes. The setup where they try to laugh because they're embarrassed also enhances the eroticism and realism. However, there wasn't a sense of them losing control throughout; I felt a certain restraint driven by reason. Those who prefer polished visuals might like it, but personally, I wanted to see them dive a bit deeper into the abyss.
