Her shy, bewildered smile is adorable... In this latest work, M-girl 'Keiko Hosoda' gets her plump butt spanked with a ruler... At the girls' dormitory, she's teased by her senior, from her breasts to her belly button, then her crotch, thighs, and finally her anus, leading her to ecstasy... Handcuffed and wearing a collar, she's dragged around and made to crawl on all fours, even wetting herself... Despite her confusion, she starts to feel things and tries to hold back, embarrassed... She's definitely still under M-training, huh...? [※This is an image video.]
