Despite the blasting fury of his previous orgasms, Mike's senses were aroused enough for him to come one more time. Admittedly his load was a weak, puny thing, only a few dribbles of a very thin, watery semen, but his cock throbbed as hard as ever and the spasms of joy ripping through his loins were satisfyingly intense. Marie removed her fist from around his cock when he began bucking her faster; she dug her fingers into the cheeks of his ass and pulled him closer to her. Her propped-up legs kept her from moving very much, but she managed to twist her ass from side to side strongly enough to add a measure of participation to his strong fucking action. Crying out with feverish delight as he rammed his big prick into the depths of her strained cunt time and time again, she came with a mighty enthusiasm and shuddered powerfully when her lustful pleasure peaked once more.
***It was on Mike's third trip home that he discovered the secret of his mother's relationship with Ranger. He was partly responsible for the discovery; he had called her the night before, telling her that he would leave around noon. Upon getting out of bed late that morning, he discovered a delivery truck in the area and managed to get himself a ride into Midwood. Thus he arrived home at noon, rather than around five o'clock, as he had originally planned. Marie, who had woken up that morning in an incredibly horny mood, had tried to avoid Ranger but had eventually given in to the pounding waves of sexual desire percolating through her loins. She had already allowed the eager dog to lick her pussy into two furies of climactic frenzy, neither of which had done much to satisfy her need for deep penetration, and in despair had turned to present her ass to him. Ranger had just gotten his prick firmly planted in her hot, grasping cunt and was beginning to pound that hot, quivering tool into her twat when Mike walked in; Marie had been so aroused that she had not heard him walking up outside the house.
Thus she was bent over and receiving a cunt-full of dog cock when Mike walked into the living room. He stood there for a moment, paralyzed by shock; the sight of his mother, naked, being fucked by the eager, slavering dog completely took away his mobility and power of speech. He gaped down at the unique scene for at least a minute, unable to move. Marie soon became aware of his presence, naturally, but Ranger was so thoroughly wrapped around her body that she could not dislodge him. Fortunately the dog was extremely aroused and did not take long to finish. He slipped off, sated and limp, and began licking his prick as he reclined upon the floor beside Marie.
"You… you said you were coming later!" Marie moaned, looking up at her son with a dazed expression. "I… I couldn't wait. I just had to do something, I was so horny!"
Mike's shock quickly wore off and he came forward, smiling gently. He told his mother that he understood completely and could not blame her for resorting to the dog as a sexual outlet. She marveled at finding him so understanding and forgiving but he swore that he did not think any the worse of her after discovering her in the act of fucking their dog. He seemed only too willing to prove it and began opening his trousers and pulling them down. His life guarding duties had already given him a deep tan, and he had a narrow band of white flesh around his loins which Marie found utterly attractive. Even more appealing, however, was the big length of cock which dangled from his belly. His prick was half-hard when he came towards her and she eagerly grasped it. Upon peeling back the foreskin and bonging the heavy, meaty bludgeon close to her lips, however, she paused and wrinkled her nose suggestively. She caught the whiff of cunt and left-over sexuality; the strong scent was unmistakable. Marie knew at once that her son had recently fucked Carol, or some other willing cunt, and found that the prospect of sucking his cock while it was ripe with the taste of another woman's juices had the power of exciting her immeasurably. She closed upon the tool with her lips and sucked the head into her mouth. Her tongue dug deep into the groove between the head and the shaft; her taste buds were immediately assailed with the powerful taste of ripe, lusty sex.
"Mmmm, she tastes good!" she exclaimed, pulling her mouth away from his cock and looking up at him coquettishly. "That's a nice-tasting cunt!"
Mike flushed and looked very ill at ease. He stammered out an apology and explained, telling her that Carol had called him late the night before, after he had showered and was preparing to go to bed. She had been terribly horny, and dying to fuck. They had spent a couple of passionately satisfying hours together and he had forgotten to shower after returning to his dormitory room. Marie told him that it was quite all right, though only because Carol had such a sweet-tasting young cunt, and that she did not at all object to mouthing his prick after it had been in the girl. She learned that Carol felt exactly the same way: Mike admitted that earlier in the week he had fucked an extremely attractive married woman and that Carol had devoured his cock greedily afterwards.
"She was an hot to go over there and lick my cum right out of her cunt, too!" he added. "I never saw anybody so turned on about sex as that girl – except maybe you. The two of you together, though, are just out of sight!"
Marie again wondered at the girl's readiness for any kind of sexual activity. She had heard of women who liked it both ways – with women or men – but she had thought that they were mostly figments of certain men's imaginations. It might be, she admitted to herself, that the girl was a genuine bisexual; certainly she gave every indication of being thoroughly in favor of heterosexual fucking and sucking. To Mike, she expressed her wonder at Carol's readiness to try almost anything in the sex line and received an explanation which made her hair stand on end.
Mike told her that Carol had made a confession to him that week, revealing a part of herself which she had never before exposed to anyone. She had learned her fucking techniques, she said, from her father! Her mother had suffered a series of debilitating strokes several years ago, she had explained, and had since been confined to a nursing home. Her father had had no desire to divorce the woman, whom he still loved and revered, but he had not been able to control his rampant sexuality, being no more than thirty-five at the time and still in fun command of his sexual powers. Carol had received her sexual initiation at the hands of a lusty high-school senior, a football star and a real stud, when she was only thirteen, but the experience had not been a satisfying one for her. She knew that there must be more to sex than what the football jock had shown her, and she had set to work to discover what she had been missing. Inevitably her search led her into contact with her highly sexed father and, due mostly to her own initiative, she had succeeded in getting him to fuck her. Once the incest barrier had been broken, they threw away all sign of restraint and began a campaign of educating the girl; the result was her present highly knowledgeable state. Carol's father was a masterly lover, very well-hung and highly inventive when it came to new ways of fitting a prick and a cunt together.
"And she knows about us, too," Mike added, darting a questioning look at his mother. "Yeah, I know maybe I shouldn't have told her, but after she was so damned open with me, well… You think it'd be all right?"
Marie thought it over for a minute, then said that she could not blame him for exchanging confidences with the girl, and Mike looked considerably relieved. Marie went back to sucking her son's cock, which attracted her even more strongly once she knew the source of the strong cunt taste, and soon had him primed and ready to fire a load.
He started to disengage himself so that he could mount her and shove his big rod into her cunt, but she held onto his dick firmly; Ranger's prick had already given her cunt a taste of sexual action and at that moment she most wanted to feel his load spurting deep into her throat. He relaxed after a moment, giving in to her pressure, and began fucking her mouth with greater intensity. He held her face just above his loins with both hands and started working his cock back and forth with quick, jabbing thrusts that excited them both greatly. Marie worked the big, flaring head between her tongue and the roof of her mouth, capturing the sensitive tip in a death grip and caressing the satiny smooth flesh as strongly as she could. Mike found that particular type of fucking much to his liking and began tensing his body, preparing to loose the mighty blast she wanted so much.
