I watched the first anniversary best collection of Otoshiro Sayaka, who debuted in AV in May 2020. With her tall and slender figure of 169cm and a smile that suits a beautiful girl, her wavering between curiosity and anxiety about the adult world is impressive. The 11 titles included range from her first sex to erotic plays using her beautiful legs, full of her charm. Dense intercourse where she seeks men on her own, large convulsive SEX that shakes her whole body, climax incontinence, and痴女intercourse that blames her nipples, etc., you can see her growth in various situations. In particular, the role of a high school girl doing 'papa katsu' is very realistic and the immersion is amazing. However, the editing that cuts off the afterglow of ejaculation is unsatisfactory. This is a common tendency in S1 works, and those who like clean-up blowjobs may find it lacking. Still, as a best collection that fully enjoys the charm of Otoshiro Sayaka, the content is very enjoyable.
