I watched a specialized work featuring Tanaka Nene's overwhelming 100cm I-cup bust, fully savoring the appeal of massive breasts. The opening scene, where she drools saliva and massages her own breasts, sets the tone with lewd dialogue that induces viewer arousal. In the titty-fucking scenes, stimulation through no-hands or angle variations rubs the glans against the nipples, intensifying as excitement builds. The massive ejaculation after repeated edging embodies the unique pleasure of large breasts. In the classroom scene, Nene-sensei, wearing glasses, lays a student on a desk for a 'special lesson,' guiding him to full erection through handjobs and alternating titty-fucking. With lubricated breasts gleaming and 'squelching' sounds echoing, the titty-fucking combined with blowjobs to extract semen is powerfully executed. The night assault scene uses gentle dirty talk and sideways titty-fucking to induce ejaculation, with continued action in a cuddling state leaving a sensual aftertaste. In the threesome sex, diverse positions like cowgirl and standing doggy style make the bust bounce, and Nene's satisfied smile as she licks semen while titty-fucking waiting penises marks the climax. Overall, the softness of the breasts, erotic costumes, and the actress's repeated use of 'titty-fucking' are appealing, making it a solid choice for practical use. However, the reverse titty-fucking scene ending with a breast splash rather than a sandwich shot is regrettable; fans expecting a splendid sandwich like in Miu or Momo's works might find it lacking. Additionally, the standard many-male-one-female threesome scene divides preferences. In summary, for bust enthusiasts, this is a work worth indulging in.
