Susan became more curious about Mary. The girl was either totally oblivious of being seen, or else she wanted to be seen. No one would deliberately be on a patio naked, and with a man, where they could be seen. Would they?
Mary certainly didn't look like an exhibitionist, at least not the way Susan imagined such a person would look.
It was almost as if Mary was doing it deliberately, to tease and taunt. But Mary just wasn't that sort of girl. Dressed, in public, she was a picture of virginal purity. But on the patio! Mmmmmmm! Or when she flashed her cunt in the car. Had Mary known she was exposed? Had she known that Susan and Bobby would see up between her thighs? If that was so, what was Mary after? What did she want?
Mary had always been friendly with Susan and Bobby, but not overly friendly. Perhaps Mary's smile was much brighter, sunnier than most, but Mary was a friendly, outgoing girl. Susan and Mary were not friends. The age difference prevented that, Susan thought.
The one thing Mary had done, though, was bring Susan and her son close, so very close, and to the point where they were fucking all the time. If not for Mary, Susan might not be fucking her son. For that, she had Mary to thank. It was Mary's body that aroused the boy, made his cock so very hard, and it was Mary – as Susan and Bobby looked down upon her – that caused Bobby and his mother to play around and touch each other.
Mary didn't know it, but she was the direct cause of this incestuous fucking Susan was involved in, and for that Susan was intensely thankful.
Mary was on the patio almost every minute she was home, and Susan knew where she could always find her son… at his window, looking down, his cock straining with desire, sometimes in his pants, sometimes out in the open, and sometimes he would be entirely naked.
Wearing panties and bra, Susan found her son at his window this hot afternoon.
She walked up behind him, pressing her lower body against his ass. Bobby was in his Jockey shorts, but when Susan ran her hand in front to hug him, she found his cock throbbing inside them. Looking over his shoulder, she saw Mary sprawled on the patio three floors below.
"What's she doing today?" Susan asked, peering over his shoulder.
"I don't know, Mom," Bobby said. "She's got something in her hand. Do you know what it is?"
Susan knew immediately.
It was a vibrator, cordless, run by batteries. Squeezing her son's cock through his shorts, Susan told her son the purpose of the vibrator.
"That's silly," he said. "Why use some thing like that when she can have that man's cock, Mom?"
"Maybe she's so hot she can't wait," Susan replied in a low voice, watching with him.
Mary drew the vibrator up and down between her thighs, rubbing it over her blonde-haired cunt lips. She heard her son gasp as they watched Mary insert the vibrator into her cunt and work it back and forth, fucking herself with it, bringing it close to her clit to receive the full sensation. When Mary pulled it out and began to lick at the plastic, Bobby laughed.
"Maybe she likes the taste of her cunt," Susan said. "I tasted pretty good on your cock, come to think of it."
Mary turned onto her stomach, drawing her knees beneath her body, arching her sweet, rounded ass into the air. She shoved the vibrator between her thighs, and Susan and Bobby watched her fuck herself with it again. When Mary drew the plastic up and moved it to her tight asshole, Bobby laughed again.
"Don't laugh," Susan said. "She might enjoy that. Some people have very sensitive assholes. Remember how it felt when I licked yours, fucking with my tongue?"
"Yes," Bobby whispered in a thick voice.
Susan shoved aside his shorts and gripped his cock, pumping it with a tight fist. She knew very well the pleasure Mary was giving herself down there. She wasn't surprised at all to see Mary press the vibrator against her asshole, then watch as it slipped a few inches inside. Mary fucked herself up the ass with the vibrator, twisting her hips about erotically. The vibrator fucked deeper and deeper as Mary became more excited, and now and then a soft squeal drifted up to Susan and Bobby.
Susan moved, sliding and slipping until she was leaning against the window next to her son. She shoved her panties downward, exposing her rounded ass. She pulled at her son until he was behind her, but still able to look down and watch Mary. Holding her son's cock, she brushed the swollen cock head against her ass, feeling the seeping juices from his piss hole smearing her flesh. She rubbed the head of his cock along her thigh, then drew it up and down the hot, enticing crack of her ass. She caught her son's cock between the cheeks of her ass, squeezing them. The throbbing sensation of his prick between the cheeks of her ass caused Susan to tremble with desire.
Mary was still thrusting the vibrator in and out of her asshole, slowly, with excited wiggles of her cute ass. Susan positioned the head of her son's cock against her tight asshole, feeling the tingling heat there. She arched her ass back a bit and created more pressure. Her eyes were becoming glazed now, and she could only see Mary in a hazy, indistinct outline. But that didn't matter; she preferred the ecstasy she was feeling.
Her son, leaning against her back and gazing over her shoulder, was now cupping his mother's tits, massaging and feeling through her bra. Susan's nipples burned, confined this way. She wiggled her ass against her son's cock, and before Bobby knew where his prick was going, he felt the swollen cock head move past the ring of her tight asshole. Bobby said nothing, only gasped. Susan held herself still for a moment, her asshole flexing about the head of her son's cock. The stretching sensation was intense, so very delightful.
Bobby leaned back and looked down at his mother's body. "Mom, you know where my cock is?"
"Mmmmm, do I!"
"You've got it in your ass, Mom," Bobby said. "It's not in your cunt."
"I know, darling! Oh, how I know!"
"You want my cock there?"
"God, yes!"
Bobby quickly became more interested in his mother's ass than Mary's. Leaning back, he peered down at the rounded smoothness of his mother's ass. He could see his cock, with the cock head caught inside her asshole. He gripped her hips and moved gently, pressing half an inch or so more cock up his mother's asshole.
"Ohhh, God, baby!" Susan whimpered, arching her ass to him. "Fast, Bobby! Ram your cock fast into my ass! Don't be gentle I want that cock rammed up my fucking ass hard! Real hard and fast!"
Bobby took a deep breath and, holding his mother's hips tightly, fucked forward.
"Owwwww!" Susan yelped.
The burning pain she felt as he shoved his cock into her asshole was only momentary. It was quickly replaced by a stretching, filling sensation that sent ripples of ecstasy through her. She held her body still, feeling his cock deeply embedded inside her ass.
"Oh, good?" she mewled. "Fuck me this way, Bobby! Fuck mother in the ass! Ooooo, fuck me up the ass, darling!"
Bobby gritting his teeth with the tightness his mother's asshole, began jerking his hips back and forth, watching his cock fuck in and out of that stretching asshole, seeing the pucker of it clinging to his prick. His balls smacked at the puffy, hairy lips of her wet cunt.
Susan rested on her head on the window sill, her mouth open, gasping as her son fucked his throbbing cock in and out of her asshole. She felt it burning deep inside, and the way his balls banged against her quivering cunt added to the pleasure she felt. Her asshole squeezed and flexed around his prick as he fucked in and out, almost sucking on it the way her pussy did. The contractions of her asshole were not caused intentionally by Susan; it happened voluntarily, something she had no control over. The smacking of his lower stomach against the spreading cheeks of her ass increased the erotic feelings rumbling through her. The sounds of fucking delighted her almost as much as the actual penetration.
"Your asshole sure is tight, Mom!" Bobby gasped as he fucked back and forth. "And real hot!"
"Oooo, yes, it is, baby! Fuck that tight, hot asshole! Oh, God, Bobby! I love it, darling! Ohhh, your hard, hard cock feels so fucking good up my asshole! Fuck mother's asshole… fuck it!"
Susan began to squirm about, her ass churning as her son fucked deeply. She was squealing loudly, and neither she nor Bobby realized the sounds were loud enough for Mary to hear. Susan's hair was hanging out the window, and when Mary looked up, she knew what was happening three floors above her. Neither Susan nor Bobby knew Mary was smiling wickedly as she turned onto her back and used the vibrator in her cunt now.
The deep fuck-thrust of Bobby's cock were creating an intense sensation of impending orgasm within Susan's body. It seemed to start somewhere high up, spreading out with liquid heat until she was on fire with the desperate need to come.
Susan screamed when her orgasm struck. The power of it caused her stretched asshole to clamp hard around her son's cock, and he was having difficulty fucking in and out. But fuck he did. Susan's cunt went into convulsions that made her whole body shake. Her asshole began a milking, waving, rippling motion on her son's cock, and caused him to gush come into her asshole. The creamy, thick come juice gushed so deeply, Susan expected to taste jism in her mouth. Her asshole clung to his thrusting, come-gushing cock as though starved for the come juice, squeezing and holding his cock. His balls, now pressed tightly against the puffy, hairy lips of Susan's cunt, writhed and became tight.
Susan slumped on the window sill, her tits pressed against the window sill, her head out the window, her son's cock still inside her asshole. As her vision cleared, she found herself looking into Mary's eyes. Mary was smiling up at her, and then she waved her hand at Susan.
Susan pulled herself back inside, feeling her son's cock pulling from her asshole.
"I think Mary knew what we were doing," she said to her son. "I think she knows, Bobby."
"I don't care. Mom," he said, still panting. "I don't care who knows."
"You know, Bobby," Susan said with a smile, "I don't care, either. And I especially don't mind that Mary knows."
"Why her in particular, Mom?"
"I have a hunch," Susan said, pulling her panties up. She adjusted the crotch, knowing her son loved to watch her do such an intimate thing.
"I'll tell you later," she said. "I've got to make sure first."
"Do you think I could fuck her, Mom?"
"I think that could be a distinct possibility, if I'm right."
Susan was almost a hundred percent sure she was correct in her thoughts about Mary. She was sure Mary knew all along that she and Bobby were watching her, that Mary wanted them to watch her. The thing Susan didn't know was why.
Mary had become progressively bolder on her patio. First being there naked, then playing with her pussy, then fucking with the man, and now fucking the vibrator up her ass. There must be some reason, Susan was sure. It was up to her to find out why, she decided. The idea of her son fucking that cute girl was exciting to Susan, if she could watch him fuck her. Could it be that Mary wanted Bobby, young as he was, but didn't have the nerve to approach the boy?
Maybe Susan wasn't supposed to have seen her. Maybe Mary wanted to tease Bobby with her beauty, her cunt, her tits and ass, and in that way let the boy know she was available. But why did Mary wave up at her and flash that lewd grin?
Susan and her son ate out again that evening, something they seemed to do quite a bit lately, since they had started fucking. It was almost as if she were a young girl again, going out on dates, then returning home to get gloriously, fantastically fucked by her date.
Bobby, it seemed, was bolder with his mother than ever before, even when out in public. Somehow it thrilled Susan, especially when he would gaze at her straining tits in the supermarket, or walk behind her to watch her ass. On those occasions, Susan would waggle her ass as seductively as she could and still keep a wary eye out for anyone else who might be looking.
Bobby insisted that she wear short shorts, the kind that exposed the lower curves of her ass. Susan found it excited her, too. She had seen the younger girls wearing such shorts, with the cute cheeks of their asses exposed, and now that she did it, Susan had actually climaxed once as she bent over a vegetable counter, her son behind her. The mere fact that the lower curves of her ass were exposed had caused her to come. When she had turned to look at her son, wanting to tell him what happened, she saw his cock was bulging inside his jogging shorts. She grinned at him, looked about, and quickly pulled the crotch of her short shorts to one side, giving him a brief peek at the curly hair of her pussy.
Bobby, she was delighted to notice, had almost shot his wad in his shorts then.
Susan laughed, and finished up with the shopping hurriedly. She kept her son close to her as she shopped, whispering in his ear.
"You're hard," she whispered. "One of these women will see your cock and grab it. It sure looks good, baby."
Bobby made no effort to conceal the outline of his hard cock, even when one woman stared directly at it. Susan saw the expression in the woman's eyes, and it was obvious to Susan the woman was excited, aroused, and probably had a very wet cunt at that moment.
They hurried home with the purchases, Susan burning up to have her son's cock fucking her. As they started up the stairs to their apartment, Mary came out of hers. She greeted them.
"Hi," Bobby said brightly, not concealing his interest in the beautiful girl.
Susan smiled at Mary, then saw the direction Mary's eyes went. Glancing down, she saw her son's cock still pressed out hard against his jogging shorts. Looking back at Mary, she saw the heat in those eyes.
Mary, after looking at Bobby's big cock-bulge, looked at Susan and smiled in a cute, yet wicked, manner, then left the building.
Inside their apartment, Susan dropped the bags as soon as the door was closed, grabbing for her son's cock.
"She wants your cock, Bobby," she said, her voice husky. "You see how she looked at it?"
Bobby nodded, more interested in his mother because she was instantly available.
Susan drew his cock from the leg of his jogging shorts and, releasing it, began to strip her blouse and shorts from her body quickly, her eyes hot.
"Fuck me!" she said, almost screaming in her need. "Fuck me now!"
Susan was near the couch, and she fell back on it, spreading her long legs widely, arching her hairy cunt up, her hands pulling the puffy lips of her pussy apart. Bobby dropped to his knees between his mother's thighs and, leaning forward, began to run the flat surface of his tongue up and down her wet, slippery cunt lips. Susan thrust her hips into his face, grinding and mewling. Bobby shoved his shorts down as he licked at his mother's cunt, then he raised his face from her pussy and moved his cock to her cunt.
Susan lifted her crotch high, drawing her knees back against her tits. Her ass was lifted as her son fucked his prick into her pussy.
"Ooooo, yes!" Susan wailed, grinding against his cock as he started plunging it. "Fuck me fast, Bobby! I'm so Goddamned hot… in the store, then seeing Mary look at you… ohhhh, I'm so fucking hot! Fuck mother! Fuck mother's wet cunt! Fuck me, fuck me, fuck me!"
Bobby clung to his mother's twisting hips, watching his cock being devoured by her hair-lined pussy. He could stand on his knees without moving, and his mother would fuck him frantically, doing all the work. Her cunt pulled at his prick, the pussy lips sucking it, and she kept wailing with the boiling ecstasy, her head twisting about as she whimpered and sobbed. She churned her cunt on his fucker hard and fast, and suddenly his cock slipped out. Bobby, in his rush to have his cock back inside her cunt, rammed forward.
"Oh! Yes!" Susan screamed.
Bobby's cock fucked into her asshole instead of her cunt, and it sank all the way.
"Fuck my asshole!" Susan screamed, clawing at her cunt with both hands now. "Fuck mother up the ass!"
Bobby pressed his hands at the back of his mother's thighs, fucking his cock in and out of her uplifted asshole. He stared with excitement as his mother finger-fucked her cunt with one hand and rubbed brutally at her clit with the other. The stimulation of her finger fucking into her cunt, the violent twisting and pulling of her clit, and the throbbing heat of her son's cock burning inside her asshole, sent Susan in to wild convulsions quickly.
She came, gurgling and murmuring incoherent words. She twisted and churned her ass up and down.
"Ooooo! Ohhhhh!" Susan wailed.
"Uh… uh… uh!" Bobby grunted.
Through the violence of her orgasms, Susan still felt the hot, hard throbbing of her son's cock deep inside her asshole. Jerking her hands away from her hairy cunt, she ran them down and behind her uptilted ass. She clawed at the smooth, round cheeks of her ass, pulling them widely apart, wanting her son's cock to fuck deeper and deeper.
"Come, come, come!" she yelped. "I want that cock coming up my fucking hot ass, Bobby! Ohhhhh, darling, fill mother's hot ass with that sweet, sweet come juice!"
Bobby was fucking in wild motions, grunting heavily as his prick strained, his balls drawing up very tight at the base of his cock. His handsome young face was twisted into a grimace of intense ecstasy, his eyes squeezed shut. Susan pulled at her ass cheeks, trying to spread them more so he could fuck very deep.
"I'm about to… I'm gonna… come!"
"Yes, yes!" she gurgled, fucking her ass up and down on his cock.
Bobby shoved as deep as he could with his cock, his balls pressing tightly. He gave a loud grunt, then came.
Susan felt her son's come juice as it splashed deep inside her ass, triggering a more intense orgasm inside her bubbling cunt. Her clit seemed to become knotted painfully, and the hair-lined lips of her pussy clenched in twitching delight.
With the final spurt of come juice into his mother's asshole, Bobby slumped forward.
Susan spread her knees so he could rest on top of her, his breath searing her tits. She cuddled him tightly, kissing the top of his head as he rested. Her feet dropped to the floor, the hot, smooth, inner surfaces brushing his hips. His cock dragged up to the sensitive lips of her cunt, and still another orgasm ripped through Susan.
"Ohhhhh…" she mewled softly, the orgasm not as strong as the others, but so pleasant to her.
"I'm going to get Mary for you," she whispered as she caressed his hair. "I'm going to get her for you, darling."
