A man is forced to abstain from masturbation while hospitalized due to an injury that has left him unable to move his hands. Even though it was only for a few days, his sexual desire explodes, and he can't hold back any longer, so he asks his busty sister-in-law Julia to help him masturbate...and to his surprise, she agrees! While secretly caring for his injured body in the hospital, she slowly and gently strokes his dick, and even straddles him and gives him a slow cowgirl ride with her sticky hip movements. At first she's reluctant, but her sister-in-law gets serious about his fully erect cock, and they have three vaginal ejaculations!
