Ga-yung takes Kyung-Ho with her to see something interesting...it's a couple fucking outdoor. They get her all fired up and so she initiates the sex despite Kyung-Ho not being comfortable doing it outside.
After fucking Ga-yung, Kyung-ho gets out to get some fresh air where he runs into Seung-ah. Thet chit chat a bit but they horny super quick & fuck in the open.
