I'm losing my mind over my pretty sister-in-law, especially that glimpse of her armpits under her sleeveless top. I want to sniff them, lick them, and ram myself into her—my self-control is hanging by a thread. I know I shouldn't, but the temptation is too much. Get ready for the ultimate armpit fetish experience.




















A work for armpit fetishists. Abeno Miku's stubbly armpits were absolutely top-tier!
Focusing on an armpit fetish is a great concept. The opening, where they lick the armpits over and over, was exactly what I was hoping for. But after that, it just became average. Once the actual intercourse started, it turned into a completely standard scene. I wish they had stayed focused on the armpits until the very end and really pushed that angle to the limit.
There were many scenes focused on her armpits, but I doubt it would satisfy someone with an armpit fetish. I felt the scenes were overly biased toward tracking the armpits; I wonder if they misunderstood the direction of an armpit fetish, or if they were just worried about keeping the perspective of non-fetishist viewers in mind. I don't know the true intent, but in terms of casting and content, I think it's above average.
The plot is exactly as the title suggests: a brother-in-law gets turned on by his wife's sister's armpits and has sex with her. The highlight this time is the scene where Miku Abeno plucks her armpit hair with tweezers. As with most of the series, the scenes where the heroine shows off her armpits in the drama segments feel a bit forced. There are more natural settings, like during baton practice, aerobics, or yoga, rather than while the family is hanging out. In that sense, the hair-plucking scene was good. Also, despite the 'turned on by armpits' premise, the actor's performance lacks a real fetishistic feel. He does expose and lick her armpits, but he doesn't look obsessed with them. I wish he had shown more fixation, like licking them relentlessly during missionary position.
