This work features Yokomiya Nanami and Tenma Yui, portraying a forbidden relationship between siblings. Nanami's adorable younger sister character and Tenma's bewitching performance shine in this production. Knowing there is also a sister version available, one might be able to enjoy a more realistic development. Especially, the scene of Nanami wetting herself in the bathroom and Yui's cunnilingus scene leave a lasting impression.
