The months passed with Sue living in their home when Helen was away on business trips. Sue often came home from work and prepared her lovers' meals, so they could study. Chris and Jill maintained their marks, and with Sue's help, had time to love each other. The nights were filled with cries of passion, the taste of sex and the shudder of orgasm. Life was sweet and they fell into a pattern that would almost lead to their down fall. Helen remained unaware of Sue's attachment to her children. Helen knew the children loved Sue and they blossomed under her guidance; their marks were excellent. Helen felt able to concentrate on her work. Everything went smoothly until one night when Helen was in Boston. The gentleman she was to meet was hospitalized suddenly and the meeting canceled. Luckily, she found a flight home that would have her in her own bed by eleven o'clock. When Helen walked in the door, the house was in darkness. She flicked on the kitchen light and found the kitchen immaculate. She was pleased the children were keeping the place so tidy while she was away. Helen moved through the house quietly. She didn't want to disturb the children for she knew they had school the next morning. As she headed up the stairs, she heard moans coming from her son's bedroom. Worried, Helen moved to investigate.
Through the open door, in the light coming from the street lamp she saw Chris Sr., nude and thrusting into a woman. She was about to charge into the room when she realized it couldn't possibly be her husband. It was Chris Jr. screwing some woman in her house. Her thoughts raced. 'Bloody damn! I'm going to do something about this.' Then, the light fell on Sue's face. Helen was shocked by the revelation; Chris Jr. was making love to a woman her own age. Frozen, unbidden pictures of her own body beneath his came to mind. Helen understood that seeing her son, who looked so much like his father, in the act of love brought back the sweet memories of her husband and their nights of love. She stood in the doorway watching. Instead of mounting anger, passion was her dominant emotion. Helen lifted her skirt, feeling through the gusset of her panties the copious amounts of viscous fluid she produced.
The children's saving grace was the call of nature Jill had answered just moments before Helen's arrival upstairs. That call, not even passion can long disallow. Jill was in the bathroom sitting on the toilet with the door open when her mother came up the stairs. Jill watched as her mother silently lifted her skirt. If her mother stayed focused on the scene before her, Jill could easily sneak to her room. For now, Jill didn't move. Instead, she watched Helen watch Chris. Sue's moans and the bucking of her hips lent visual clues to the cause of Helen's mounting passion. Helen unfastened the buttons on the front of her dress and stood with her bra and panties exposed.
As Helen watched, the couple before her stopped and to her surprise, Chris turned around and lay down on his back. Chris' cock was rampant. Sue rolled on top of Chris taking his engorged cock in her hand as her mouth descended on it. Chris' head was clearly between Sue's legs. Although Helen couldn't see, she could imagine the hot sweetness of male tongue on her own highly aroused sex. Helen eased one of her breasts out of its cup rolling the swollen nipple between thumb and forefinger. Her other hand slid into her panties; her middle finger slid over her clitoris as it entered her body. Helen could see her son's hands gripping Sue's ass as Sue worked it against Chris' face. Watching the lovers, Helen replaced one finger with two fingers then three.
Jill put her own fingers into her snatch coating them in her juices and watching her mother's hand increase speed. Suddenly, Helen stopped, hooked her fingers into the waistline of her panties and brought them to her knees. Then, her hands resumed their pleasuring. Still unsatisfied, Helen bent, took her panties off and kicked them across the hall with one foot. Jill, still stroking herself, soon fell into a gut wrenching orgasm as she watched her mother watch her brother. Legs now spread wide, Helen stood with three fingers dancing in her pussy. Her hips thrust on her fingers in time with Sue's hips. Suddenly, Helen came with her teeth clamped shut stifling the cries she wanted to emit. As soon as she regained her senses, Helen took her hand from her pussy and rushed to her room grabbing the panties from the floor as she passed. Helen closed the door softly.
Jill hurried to her brother's bed but paused as she recognized Chris and Sue were about to achieve orgasm. She stood and watched as their bodies shook with release, loving them in their bliss. The moment they were finished, Jill rushed to speak. The fact their mother was in the house was quickly assimilated and plans discussed. They understood they had been extremely lucky. Had Jill been in bed with them as she had moments before their mother arrived, they were sure their mother would have exploded on the spot. As it was, they remained in a sticky situation. Helen knew Sue was in the house. They couldn't simply sneak Sue home. They decided Sue would stay and serve breakfast just as she had every other morning. If Helen wanted to bring up the issue of Sue having sex with Chris, they'd fight that battle when it came.
