Wanda was moaning softly as she sucked Tommy's tongue writhing her ass on the couch, opening and closing her legs. Susan saw her son had his hand inside Wanda's panties. She watched as her sister pumped her fist up and down Tommy's cock, and listened to the groan of pleasure he made. She had not seen his cock before, not like this. She had seen it pressing in hardness against the front of his pants, but never standing free and naked. It was larger than she had expected.

"Well?" she finally said.

There was an immediate reaction from Tommy and Wanda. Wanda gave a little scream as she jerked her mouth away from Tommy's tongue, pulling his hand from her panties at the same time. Wanda sat upright quickly, clamping her knees together and flushing with shyness. Tommy, seeing his mother standing in the doorway, stuffed his cock into his pants. Susan almost laughed at the trouble he had because it remained hard.

"I see I got home just in time," Susan said, closing the door. She was trembling, and her cunt seemed to be throbbing with heat.

Tommy didn't appear embarrassed at all. It was Wanda who blushed and couldn't look at Susan. Susan placed her purse on a table and turned to look at her son and sister. Wanda was only a few years older than Tommy, about the prettiest blonde in their old hometown. She was sweet and cuddly and shy, with an innocent way of looking at a person that said she wasn't as innocent as she appeared. Her sky-blue eyes promised and teased. She was curvy and slender, like Susan.

"When did you get in, Wanda?" she asked. Wanda whispered something, but it was Tommy who answered. "She got here about an hour ago, Mom."
