I'm a college student with a girlfriend, and her younger sister, Nanami, is a high school girl. Despite her quiet appearance, Nanami is actually a masochist. One day, noticing that I'm watching her, she tempts me by showing off her masturbation. Surprised but intrigued, I decide to train this perverted sister. Secretly, behind my girlfriend's back, our relationship escalates, and through bondage sex, she is transformed into a complete masochistic slave who repeatedly reaches climax.




















It's a submission-themed piece, but if you're used to the hardcore stuff from Director Ota Migiwa, this will feel way too soft. That said, her physique is absolutely stunning, and the romantic vibe is great. The best part is her 'little devil' act, seducing her sister's boyfriend. She's so cute when she's being obedient that any guy would fall for her instantly. I love the irony of her being the 'slave' while actually dominating the man.
Damn, this is erotic. The scenes with the ropes hidden under the coat and dress are absolute gold for a quick session. But then I started wondering, "Wait, who actually tied her up?" and that plot hole totally killed the mood lol. I think using rubber restraints would have been more natural and way sexier. Also, the audio. I don't know if this was mixed specifically for headphones, but the dialogue is way too quiet. I can tell she's saying something dirty, but I can't actually make out the words.
Features Nanami Yokomiya getting her belly button licked twice. Once in a cosplay outfit, and again while tied up.
Nanami Yokomiya absolutely nails the 'obedient slave' vibe here. Watching her show off her masturbation to her sister's boyfriend and beg to be a slave, then binding herself with rope just to be trained... it hit every single one of my kinks. That scene where she sticks her ass out and begs for spanking had me shaking; the excitement just wouldn't fade. There's something about Nanami that makes you just want to ruin her. The 'pure girl who's secretly a pervert' trope is basically every guy's fantasy, and she plays it perfectly with such a devoted, fragile aura. Instead of being forced, she actively embraces the masochist role, which feels like a side of her we've never seen before. She looks incredibly erotic and beautiful while being disciplined. Even the dialogue is spot on! If you're into obedient beauties, this is a must-watch. Highly recommended.
