Aoi Saki's latest work, 'What Are You Doing!', is a passionate piece depicting the forbidden relationship between a mother and her son. Saki, playing the mother, is caught masturbating by her son Yuta, leading to a series of events that leave her bewildered, yet her extremely frustrated body reacts to the heated caresses. The film features consecutive creampie scenes, with Saki's reactions at the moment of climax being particularly captivating. Saki's performance, exuding a mature woman's charm, shines in scenes like the hugging missionary position and the under-the-thigh angle blowjob shown in the sample images. However, the male actor's monotone delivery of lines is a point of contention. Still, Saki's whispered 'Ah, I'm coming' as a conditioned reflex is super erotic, and her wavering between reason and instinct is a highlight. As a staple of the Senbire series, this is a film where you can fully enjoy Saki's sexy body.
