Caught on camera, a dental hygienist seduces a patient by pressing her chest against him during treatment and having sex. The dental hygienist, who is often imagined as a clean and pretty sister, is actually a lewd sister as well. 'It's so embarrassing...' she says, but when faced with an erect penis, she actively touches and licks it, taking care of it. This lewd behavior inevitably leads to a full erection. Since things have progressed this far, both parties are fully prepared, so they start having sex without hesitation. The rhythmic sound of flesh hitting flesh creates a sense of immersion, making the mood even more erotic. Furthermore, as both seek pleasure, they transform into a sex machine, moving non-stop. Naturally, the end result is internal ejaculation. A large amount of semen is released into the vagina, leading to great satisfaction. They continue having sex until their sexual desire is exhausted.
