A male actor hospitalized with a back injury becomes attracted to a big-breasted, cute female physical therapist during his rehab. Though his back hurts from the long hospital stay, his erection won't go away. Every time Akagi, a huge-titted married woman, brushes her tits against him during rehab, his dick gets rock hard.
Akagi carefully massages around the male actor's dick. Seeing his erect cock, she takes off her panties and helps him jerk off. The male actor begs to fuck her as a celebration of his discharge, and succeeds in having sex while enjoying her huge tits.
Meanwhile, Mitsumori, who looks good with a short haircut, keeps asking about the male actor's girlfriend. The male actor begs her to let him fuck her on the condition that he'll break up with her.
