"You'd get a bang out of anything having to do with sex," Rod said, patting his sister's firm ass. "I don't know if I can wait until we get back to Grandma's house or not."

Betty put her hand on his stiff cock and squeezed it through his clothes. "Don't waste your jism, man! I'll take a chance on being seen and blow you right here if you don't think you can wait!"

Rod saw that his mother was about to climax. She'd been fondling and squeezing her own breasts and she'd now out her hands on Mr. Anderson's bobbing head. Her fingers were digging into his scalp and her ass was wriggling against the mattress. Her pretty features were contorted with passion, her eyes were tightly closed, and her lips were parted.

He knew that his sister wanted to see their mother getting fucked, so he pushed her fingers from his throbbing cock and told her that he could wait. The house was well back from the street, and the neighboring houses weren't very close, but there was always the chance that they'd be seen. He also preferred to save himself for later when they could take the opportunity to have their sexual fun and pleasure on a bed.

Lifting his face, licking his wet lips and grinning, Mr. Anderson walked on his knees until his thrusting prick was aimed at the blonde crotch. He waited for her long finger to do the guiding and then slowly lowered himself until his big cock was buried balls-deep.

He lowered his broad chest down against her poking breasts and slipped his hands down and under and grabbed her writhing buttocks. Seeing his mother pull Mr. Anderson's wet lips to her open mouth, Rod wondered if her cunt juices would taste anything like Betty's tangy sweet secretions.

Betty had grabbed his cock again and he didn't try to push her squeezing and stroking fingers away. He thought about tugging the throbbing flesh and muscle out into the open for her and as he made up his mind to do just that Betty dropped down and moved her hand to the top of his pants zipper.
