After a senior caregiver is injured, newly qualified Saki temporarily joins a group home for elderly residents. Efficient, caring, and blessed with huge breasts, she immediately attracts the lustful attention of eight demanding old men whose sex drives have not faded with age. They crowd around her, grope and devour her mature body, insisting that sex is the best medicine for a long life. Her kindness is exploited as the residents gang-fuck her and drive her through repeated orgasms in a wild group session.
