Rachael just can't hold in a laugh as Dad hurriedly brought his chair over next to her, when she spotted his swinging penis through the flaps of his bathrobe. The two paused to look up to see if Mom noticed the sound of the heavy chair on the hardwood floor. But the running water at the sink probably helped them as her back stayed to them as she washed her plates and utensils.
"First, where is it?" she demanded to know.
Dad raised the fat envelope up from out his robe's side-pocket and then back down.
"Satisfied now?" he smiled, wasting no time in parting his robe to expose his hairy self to her.
"Now...shall we get things going then?!" he shook his leg with wild festivity.
She shook her head at his impatience over it all and slowly reached her arm out. He hunched over her texts and notebook on the table with pretend interest in helping with her studies, while he hardened quickly to her very gentle yanks.
At about this time, Mom turned off the water and started toweling dry her stuff.
"Honey, is she giving you a hard time with that homework again?" she asked, her back half-turned to them as she now returned items to the drying rack.
Rachael took this crazed opportunity to have a little humor.
"Am I really giving you a HARD time, Daddy?" she grinned shrewdly at him, feeling his full boner break the light ring formed by her thumb and index finger.
Marvin, though, wasn't really all there when his daughter turned to him. She was surprised to see him all glassy-eyed and sweaty on the face. His legs had shot out and clasped themselves together before him. He sat back in his chair as his hard, squeaking grip upon its corners told her of his forthcoming.
Luckily, Mom wasn't really into it for a response and just excused herself off down the hallway for her usual morning shower.
