Hinana Nanase, a Hiroshima dialect gal, makes her debut in this work, showcasing her exceptional fellatio skills. True to her words, 'It's all about the depth! If it's not deep, it's meaningless!', the film features limitless living onahole states with deep throat and vaginal penetration by well-endowed male actors. The deep throat fellatio, in particular, is so captivating that even someone like me, who wasn't particularly interested in deep throat before, was made aware of its appeal. Moreover, her superhuman skill of performing handjobs while deep throating, and her ability to keep smiling even when her face is a mess, are guaranteed to excite viewers. Even those not usually fans of threesomes will find the scenes where both her upper and lower mouths are violated to be recommendable. After watching this film, other deep throat works pale in comparison, as its quality is truly in a league of its own. With clear depictions of penis insertion into the throat, scenes of throat orgasms, and her appearance as a school gal, this is a top-tier work packed with highlights that can be enjoyed over and over again.
