One evening a week later Gramps George was in his living, room reading the paper when his daughter-in-law Lisa entered the house.

"Hi, Dad," she said, sitting down next to him on the sofa.

"Hello, dear," the older man smiled, tossing the paper aside and placing his hand on her thigh.

"Dad, I'm horny," she said, moving his hand under her skirt. "Since Mom's out I thought you might want to fuck me."

"Have I ever refused you?" he said, moving his hand between her thighs.

"No, bless you, you haven't."

For several years Lisa and George had had an unspoken agreement. When she was horny, she came to him and he gave her a good fucking. In turn, he did the same when he was horny. They had been close ever since Lisa married into the family and it seemed perfectly natural to them both that their closeness carry over into their sex lives.

Lisa sighed and toyed with the hairs on the back of his neck as he caressed her. "I wish Alan understood me as well as you do," she said.

"When he's my age, he'll have more savvy."

The big-titted brunette lay her head on his shoulder. His fingers felt so good between her legs she was sorry she'd worn panties.

"You always know just how to touch me down there," she said, reaching down and stroking the bulge in his fly.

"That's what families are for."

"Do you suppose all families are like ours?" She widened the spread of her legs when he moved his fingers over the crotch of her panties.

"If they're not they should be."

"Alan went out again and he wouldn't tell me where he was going."

"Molly said she was going to the movies with her girlfriend – but I think maybe she has a date."

"Well, she certainly is a stunning woman."

George grinned. "There ought to be a law about a woman her age looking so damn good."

"You're proud of her, aren't you?"
