His Dad looks startled and yells at Billy to get out. After finishing, the Dad starts to feel guilty from screaming at his son, so he goes around the house, looking for him. After not finding him in his room and in the kitchen, he goes to Grandma' room, where he sees Billy screwing his Grandma.
"Billy, what in seven Hells do you think you are doing?" - the Dad furiously yells.
"You see how good it feels seeing someone screwing your Mom in front of you, Dad".
