She simply felt her son would be a fantastic fucking partner, and because he was her son, Susan refused to let that sway her judgment. She had no hang-ups about fucking Tommy, none at all.

But now, with Wanda staying awhile, it would be sure to put a damper on the growing attraction she and Tommy were feeling for each other. So far, her son looked openly at her, gazing at her flawless, firm tits, staring at her ass, or peeking at her knees. Not that Susan had exposed anything to him yet, but he looked and his expression was hungry. Once, just a day or so before, he had, touched her on her hip, and both of them had gasped and frozen far a moment. She had glanced down at his hand touching her hip, then into her son's hungry eyes. Then they pulled away, and there was no further mention of the incident, yet they both had felt the electrical charge whipping through the air.

Tommy was a virgin, she was sure. She had never seen him with a girl, and he seldom went anywhere. She didn't like him to go outside very often. It was getting dangerous to be alone on the streets, with the gangs roaming about, muggings and so on. She was lucky that Tommy didn't associate himself with a gang, she thought.

Entering her apartment building, she took the elevator to the tenth floor, and quietly opened the door to her apartment.

Tommy and Wanda didn't see or hear her enter; they sat on the couch, pressing lightly together. Susan saw that Tommy had his hand under his aunt's dress and his tongue was down her throat. The next thing she saw was her sister gripping Tommy's cock very hard. She could see the head of her son's cock bulging up, very swollen and very smooth, and the glistening beads of wetness on his pinhole. Susan stood still, her eyes wide and hot, staring at her son's cock. She was afraid to breathe, afraid to make a sound. Not because she would startle them, but because she didn't want her son's cock to disappear.
