Big-breasted sister-in-law Hikari came to stay at her brother-in-law's house to go sightseeing. While they live together, Hikari's brother-in-law can't help but become curious about her breasts. His brother-in-law resists the temptation to push her down, but one day he finally can't stand it anymore and steals Hikari's attention from his wife, locking her in a closed room and forcing her to have a relationship with him. Hikari feels bad for her sister.
