Religious Mother - Part 2

Her son fucks her in the same bed where her husband is fast asleep. The family is on a trip. Unable to reach their destination before dark, they have to spend the night in a motel, in which there is only one room available with a single bed. Father, mother, and son have to share it. They are good religious, and they commend their souls to the Good Lord before going to sleep. But as soon as the father falls asleep, the young boy and his mother can't resist the temptation.
