Lewdness under Kimono - Widowed landlady comes in front of the grave

"I can't control my lust even though he is my husband...!"
Sanae is a beautiful proprietress who has been running a Japanese inn by herself since her husband died 10 years ago.
One day, her junior in high school, Aiko, and her husband, Teppei, come to stay. Seeing Teppei, whose face somewhat resembles her husband's, her pussy unintentionally gets hot under her kimono....
That night, when Sanae was taking a hot spring bath, she unexpectedly ran into Teppei! As Sanae rushes to get out of the hot spring, Teppei embraces her wet body with all his might! He caresses Sanae's breasts and pussy, and she can't help but scream.
Then, she accepts a man for the first time in 10 years, and her pussy is soaked with hot water and love juices...!
She is not allowed to do this, but the pleasure is too strong, and she finds herself shaking her hips...
The next day, Teppei sees Sanae going to visit her husband's grave.
