After seeing my twin sister Oba masturbating in VR, I impulsively asked to touch her breasts. "We're siblings! That's impossible... but, just a little..." Unable to suppress her erotic curiosity... the two eventually reached the point just before insertion and decided on a rule: "Inserting up to the first 3cm isn't considered sex," and began repeating anal sex. However, even just the tip going in and out of the vagina felt significantly good, and they gradually wanted to insert it deeper... The precarious life of a twin sibling with near-full penetration!

















The series has returned after 4 years since the previous installment, and the time gap helped avoid staleness, allowing me to enjoy the work afresh. Unlike the previous works which built up tension before going full throttle at the end, this one features a cycle of giving in and deeply penetrating, then returning to 'rules' with a scolding tone, deviating from the 'classic' flow. I thought it was very well-crafted. Goba-san's lead role was a brilliant choice, and her acting and seductiveness are both skillful, so I could watch it without getting bored until the end. The actor playing the twin brother is also handsome! This is a masterpiece, I acknowledge it.
Goba-chan has become even more beautiful and feminine lately, really shining. The story revolves around her falling into a forbidden sex with her twin brother (Chiose Kome). The way she emphasizes her butt while being handjobbed and penetrated by her brother is super lewd, with a clear view of her anal. Her body line from the hips down is incredibly beautiful, and her breasts peeking out from her rolled-up sailor uniform, along with her perky nipples, are just too erotic. Her naked body with only white high socks, moaning during cunnilingus, tongues entwined in a French kiss, being penetrated from behind in cowgirl position, and her breasts trembling like jelly while arching her back in missionary position… it was all so stimulating. This work fully indulges in Goba-chan's beautiful body line, anal, and nipples, and it's the most captivating J-style work of hers so far. Definitely a keeper!
