After a traffic accident leaves both of his arms injured and confines him to bed, his concerned teacher Maki visits his home. She feeds him and gently wipes down his body, but being unable to masturbate has left him painfully pent-up, and her touch makes him hard. Instead of pulling away when she notices, Maki eagerly climbs over him. Her frustrated desire turns full-body caregiving into intimate sexual service, transforming a miserable bedridden existence into blissful recovery.
