"Something...something hard and great feeling is inside me...!" - - The office worker Miyuki is troubled by hip pain when she is dragged along to a chiropractor's office by her coworker. What should've been just a massage, joint adjustment and a loosening of her tight muscles... ends up with her going along with his skilled hands and suddenly being totally naked! She's blindfolded and something hot and hard is hitting her in that dripping place down there... but this is just treatment so it's not sexual, right...!? Unknowing what it could be something thick and amazing feeling of the chiropractor's is shoved deep inside her, and she cums again and again as she cries out in a sexy voice...!!
