Rod saw Mr. Anderson tense, then shudder violently, and at the same time his own cock jerked spasmodically and sprayed Betty's tonsils with hot jism. He made little hunching movements as his sister continued to suck greedily while swallowing the thick and sticky cream she liked so very much.

His mother and the history teacher collapsed just as Betty was draining the last drop of sperm from his rapidly softening cock. She let Rod's limber dick slip from her mouth at the same time as Mr. Anderson flopped over on his back, his big cock limp and glistening under the overhead light.

Betty had pulled her finger from her cunt. Rod knew that she'd climaxed. There was enough light for him to tell that by the satisfied look on her pretty face. He helped her to her feet and accepted her passionate kiss. He'd tasted his sperm on her lips before. She pulled her mouth and tongue from his and looked in the window. He saw that their mother was swinging from the bed, a towel clutched between her legs.

"I guess Mr. Anderson really gave Mom a good fuck," Betty whispered.

"He did that," Rod said, lifting his sister's wet finger to his lips. He took the digit into his mouth and sucked, enjoying the taste of her cuntal juices. "Are you ready to go to Grandma's house?"

Before Betty could answer another couple entered the bedroom. They'd seen the man and woman before, but they didn't know their names. The woman was short and had red hair. She had big titties and look to be about twenty-five. The man was also short and looked as if he might be pushing forty. He had dark hair and his cock didn't look to be over five inches long when thrusting stiffly – as it was doing by the time they were both naked.
