"No, don't go away," she said softly, surprising herself still more. "Let's look at her, honey. Let's both stand here and look at her together. No harm in that."

She pressed her hip against him, feeling his body shaking, but he remained where he was, still trying to conceal his exposed cock from her. Susan felt so strange, so aroused, so ready! She was not herself, but someone else, a woman with a steaming cunt that seemed to be taking control of her, making her emotions whirl. She flexed the cheeks of her ass, trying to peek at her son's cock as he tried to keep his hard-on pressed against the wall.

"Would you like to… do things with her, darling?" Susan heard herself asking her son.

A mumbled grunt came from Bobby, and she pressed her hips tighter against him.

"Does looking at Mary make you excited, so you'd love to touch her, run your hands over her flesh, Bobby?"

Susan shivered, unable to stop this outrageous talk to her son. She stared down, trying to see the lips of Mary's cunt, and still could only see how the hair parted, nothing else, except those firm, upstanding tits.

Her hand moved, and she trembled over what she was about to do with her son. She squeezed her hand between his hips and the wall, and felt Bobby press harder, as if to prevent her hand from touching him.

"It's all right, darling," Susan whispered. "Just look at Mary and pretend, think of it as her hand. Think of what you'd like to do with her… how you'd like to touch her, where you'd like to touch her."

Her voice came out low, whispery, filled with heavy desire. She felt her son shaking as her hand moved between his body and the wall. Her fingertips contacted the hot hardness of his cock, and with a gurgle of success, Susan closed her fingers around the boy's prick.

"Oooo," she murmured as she squeezed her son's prick. "Keep looking at Mary, darling. Keep thinking what you'd like to do with her, to her. Isn't she pretty, Bobby? See how her breasts stand up so sweetly, those hard nipples, pink and sugary? Wouldn't you like to kiss these nipples, honey? Run your tongue over them, suck them into your mouth?"
