"Hi, Matt," she beamed, still finger-fucking herself when the handsome young man walked into the room. "I'm getting my cunt all warmed up for you."

"Gee, Mom," he grinned, standing completely naked with his throbbing boner spearing straight up in front of him. "I didn't know the thing ever cooled off." He crawled onto the bed.

When Hope got over to her girlfriend's place that morning, she found out that the girl had to go shopping with her mother for some clothes. Feeling a bit disappointed, Hope pedaled her bike home.

Entering the house, she heard soft giggles coming from her mother's bedroom. Hope was about to enter the room when she was suddenly stunned by what she heard.

"Oh, Matt," her mother giggled. "I just love your nice hard cock."

The door was slightly ajar, and unable to believe what she was hearing, Hope peered through the open crack. The breath caught in her throat when she saw her mother and big brother spread out completely naked on the bed, but the thing that really shocked her was the size of the hard cock her mom was holding in her hand. Hope had never seen any pricks except on little baby boys when the mothers had been changing their diapers. She couldn't believe that her brother had such a big cock.

Hope's mother was lazily sliding the tightly stretched cock-skin up and down over her son's big naked prick while he lovingly rubbed his hands against her hard, swollen nipples.

"God, honey," Lisa smiled as she continued stroking her son's boner. "I can't believe this is the same cock that you first fucked me with."

"It's a lot bigger now," grinned Matt. "It sure is," his horny mother smiled. "It was only about four inches long then, and now it's such a beautiful big cock."

"That's because you gave it plenty of exercise," he laughed. "And now fucking is my favorite sport."

"It's mine, too," his mother giggled, giving his hard prick a loving squeeze.
