Quick review: Rion plays a busty teacher who suffers sexual humiliation and abuse by school superiors and students alike, the new twist this time is her pussy is shaven.
Rion has done a few humiliation vids, this one is a bit "enhanced" relative to all her past humiliation vids that there's a bit of story plot arc, and she acted out several lines of dialogue for the plot. Specifically, she was teaching a class with a few physically healthy and menacing students who made her rather uncomfortable with their lecherous staring. She left behind a copy of the term exam papers in the classroom and found by the students. Then Rion is scolded by the principal because of her mistake. The principal decide he can forget her mistake if she would agree to his sexual perversion, he tells her to shave her pussy and come back the next day. (how odd he told her to shave herself at home by herself and (most critically) unseen by the camera)
Scene 1: she's back, in the usual teacher/OL white shirt-and-black skirt. He strips off her cloths (some fans like seeing these mild force used) and especially focus on her pussy (for once not entirely focusing on her tits). Very very strange that he puts shaving cream on her pussy and do a lot of pussy play but in fact it's already clean shaven. If he's paipan obsessed wouldn't it makes sense for him to perform the shaving? I am not crazy about this genre, but even I'm excited to see pubic hair being trimmed, cut or shaved. Obvious conclusion is that Rion personally did not agree to film the act of shaving.
Otherwise, scene 1 is fine, pretty much as you could expect in a Rion performance. The scene finished with the principal fucking her from behind (her signature sex act highlighting her massive swinging jugs) and just before he orgasmed he turned her around and make cum onto her tongue. It's a fairly weak cock and ejaculation, and Rion's her usual self, being pretty but fairly passive in the fucking. Still you gotta admit it's pretty hot watching she get sloppy sperm in her mouth and face.
Scene 2: those students who found the exam papers and caused her all the trouble pass by the corridor and noticed Rion being sexually molested, they capture a bit of the action (especially her hairless pussy) on their cell phone. Later this was found by the teacher in charge of disciplines so of course the 3 of them use this to blackmail poor poor Rion. Compared to scene 1, scene 2 is much more S&M, as they tied her up and gag her with her own black panty. And they take turn to molest and r*** her.
Scene 3: there's no transition story, a bit disappointing... Rion walks into a classroom and got surrounded by 5 students holding up photos of her previous abuses. She's far from being pleased but seems more resigned to her fate. They don't need to lay a hand on her before she started stripping herself naked. Instead of molesting and raping her, the boys only touch her lightly before making her put on an all-white one-piece swimsuit. Then they begin molesting her with slime, fingers and vibrator. Of course attention is paid to her hairless pussy lips (the swimsuit crotch stays on mostly to reduce the need for mosaic). Finally the boys switch to their own pleasure seeking instead of humiliating and abusing her. They make her such their cocks and they cum in her mouth or on her face and tits.
Scene 4: Rion is teaching again, but something is definitely off. The principal and discipline teacher enters the classroom and interrogate why she's not teaching properly. The discipline teacher seems to guess where the problem is. He pulls up her tight black skirt up to expose that she is naked inside her panty hose and a vibrator is buzzing noisily in her pussy. The principal is "shocked" as he inspect the going on closely. There's only one thing to do, the two male teacher and the 5-ish students all gang up on her and give her what she deserve, molesting and oral and vagina raping. As usual they deposit cum all over her chest and face especially the final cum load was dripped on her face and a bit into her nostril.
So again Rion is perfectly willing to have cocks (with condom I guess) shoved into her vagina and mouth and receive sperm on her chest, belly, face or even in her mouth. But she is unwilling or very weak in engaged sex and for this title she did not let the fan see her pussy being shaved.
For a Rion vid, -126 is well above average. But on the same day, S1 put out SSNI-121 starring Nana Fukuda in a very similar title (without paipan). Why S1 have their two bustiest contract girls release the same theme on the same day (even the setup and sex scenes are very similar)? It goes without saying Nana is a bit inferior to Rion for both face and figure, but is it just me? Seems Nana's sexual performance is better. So even with Rion being hotter and the added novelty of paipan I would rate the two vids about equal, overall.
