"Fuck my ass," Jennifer Smith was whimpering aloud, breathing and biting into the soft pillow beneath her head. The 39 year old glasses-wearing assistant sales-director, wife, and mother of two was positioned on her marital bed on hands and knees with her perfectly shaped ass in the air. Her husband Tim was sitting in a chair in the corner pumping his own meat, and her 19 year old son Mark was sitting on his knees behind her, about to insert his 8 incher into the only orifice belonging to this mother that he hadn't taken yet.
Mark had been fucking his mother in the presence of his father ever since that day earlier in the week when they had surprised Jennifer with the fulfillment of one of her greatest fantasies. The young man and his mom had been living out their fantasies in the subsequent days while Tim stayed clear for the most part.
There were short periods during the days that Jennifer thought about how it had come to this. It was not too long ago, after all, that she and her husband barely had what could be called a successful marriage. Their sex life had gotten to be virtually non-existent.
Was it this fact, perhaps, that initiated Jennifer to start paying attention to the physical development of her son? Was it her need for sexual release, and not getting it from her husband during the past few years, that had made the brunette watch her son with an eye that was not altogether 'motherly'? It was about a year ago that Jennifer had made herself cum deliberately whilst thinking about her son. She had been feeling guilty for a short period after that. But it wouldn't stop her from repeating it, until finally she stopped feeling guilty altogether about fantasizing about, and masturbating to thoughts of having sex with her boy.
After some heavy arguments and an emotional breakdown, Jennifer and Tim had finally gotten their issues out in the open, and the process of repairing their marriage had begun. To both their delight, the love they felt in the beginning came back in spades, and their bond became even more intimate than it ever was.
When their mutual trust was earned back again, they had been revealing their innermost sexual fantasies and their sex life had never been better.
Despite the fact that their marriage was back to being the way it used to be, and their bedroom antics fresh and revived, Jennifer did not stop having her secret fantasies. The gates had been opened, and there was no turning back. The mother was happier than she'd ever been the moment she had revealed her secret incestuous fantasies to Tim, and found out that rather than having a problem with it, it turned him on to no end. It felt like a big wave of liberation crashing over her.
In a declaration of sorts of his love for his wife, Tim had secretly been working on gauging his son on the subject of taboo love, and subsequently preparing Mark to fulfill his mother's fantasies. The rest is history.
Mark had been jerking off thinking about doing his very own mother for years. Ever since the boy had gotten into the rhythm of masturbating and fantasizing, images of his mother started running through his mind. He had always loved her dearly, but his mother's physical beauty also never went unnoticed with him. When sexual imagery started playing a part in his teenage life, he started noticing the curves of her body. His sister's body didn't exactly go unnoticed either, but it was his mother that did the trick more than anything.
He would pay attention in ways unbecoming a son, to the shape of her tits behind her shirts and sweaters, and at some point even her bra when he caught her coming out of the bathroom in just her underwear. That instance was the single greatest moment of his teenage years, as Jennifer's nipples were hard and were poking clearly through the material. Outside of seeing her tits bared, there was no way he would have gotten a better view of her fleshy boobs.
Her ass didn't go unnoticed either. He would pay close attention to it when she would wiggle it while walking by, or when it was flattened as she sat down on a chair. At those moments, there was nothing he wanted more but to lay his hand on the seat of the chair, palm up, and feel his mother sit her soft rump down right on his upturned hand.
There was basically nothing about his mother that went unnoticed from that period on. The shape of her tits and ass, even if covered by clothing, were enough to stimulate his hottest fantasies. The clothes she wore could add spice to them, especially when she decided to go to work wearing skirts and nylon stockings. He would have given anything to see his mother in those hot looking lingerie things. Those garter belts with the stockings attached to it with elastic bands.
She could lick her lips and Mark would wonder how it would feel if she licked his lips instead. His fantasies about his mother turned gorgeous women that wear glasses and have their hair in a bun into a fetish or sorts. Thanks to his mother he would always find women like that hot somehow; the mousy-yet-good looking librarian types.
As the years of his teenage-dom passed by, he had also learned to sneak into his parents' bedroom, particularly when they were out of the house. He would look around and invade their privacy by checking out the cabinets and closet. He hit the jackpot one day when he found his mother's vibrator in a box in the back of the closet.
His entire body trembling with excitement and suspense, he imagined the white object being shoved in and out of his mother's cunt. The surface pushing in the ridge of her vaginal opening, and making her labia wrap around the rod as she pushed the vibrating fuck stick into her wet, sucking hole. And then the surface of the vibrator, pulling the rim of her pussy-opening outward, and her labia moving aside again, as she pulled the buzzing cunt-poker out of her hairy snatch. In his mind, Mark could see his mother lying on her bed completely naked, wearing nothing but her glasses, her brown curly hair spread out on the pillow, and panting. She would squeeze a tit with one hand, twisting the dark, stiff nipple of it between thumb and index finger. And with the vibrator in her other hand, she would fuck herself hard and fast; the buzzing fuck-stick making squelching sounds as it slipped in and out of the hair framed slit. She would spread her luscious legs wide and pull her knees up toward her tits, thus exposing her whole crotch, from her knotted clit to her dark, wrinkled asshole twitching in the crack between her soft ass-globes. Her toes would curl as she would wrap both hands around the humming tool to poke it mercilessly into her sucking, sloshing twat. Her tits would be caught between her stretched arms and bulge outward, the nipples stiffer than normal. A grimace of self absorbed lust would take over her pretty face. The contrast between the 'librarian' look of his mother, and the expression on her face would be great. A beautiful, yet somewhat nerdy looking woman, and hot, masturbating slut both in one body.
In his fantasy, Mark could almost smell it. The smell of his mother's pussy as it was being invaded time and time again by the battery powered sex tool. The scent of a hot, masturbating mother filling her bedroom.
Mark had then wondered if he would be able to smell her; smell his mother, on her electric fuck buddy. He had held the white rod under his nose and although he couldn't compare it to anything he had known, he had smelled something on the thing that sent a shiver down his spine. Could have been more the idea of smelling his mother's cunt on the vibrator than the smell itself, but it had made his knees weak nonetheless.
He had decided to take a little lick, just to find out if it tasted like... well, what was supposed to be pussy. But after a few licks he determined that he just had no real way of knowing what it was that he tasted, and whether it really was his mother's dried juice flavor.
Ever since that day, Mark would often see, feel, smell and taste the thing. Just the notion that his mother was using it to fuck her needy, horny cunt had been more enough for him to get himself off playing around with it. He had loved the idea that the vibrator was rubbing against his cock and balls, and would then later be inside his mother. Somehow, it made him think that at least somehow, part of her pussy was making contact with his cock and balls, and part of his dick and balls were making contact with his mother's vagina.
Not having been satisfied with playing around with her vibrator, Mark would also often rummage around in the dirty clothes hamper, looking for treasures. During the years he would use both the dirty panties of his sister and his mother, but mostly his mother's, to jack off. Often he would either hold the inside of them under his nose, or turn them inside out and ball them up to stuff in his mouth while he pumped his cock thinking about eating her out. Other times he would turn them inside out and wrap them around his shaft to jack off with them.
In the end, throughout the years before the present day, Mark would have turned out to have prepared himself for doing the real thing. The only thing missing had been his mother's actual participation. The thought of committing incest with his mom would not be new to him, and his father wouldn't need much to convince him after carefully telling the 19 year old about his mother's hidden desires. Quite the contrary, once Mark realized his dad wasn't kidding, he thought he had died and gone to heaven.
His mother's secret fantasy had been to fuck her son; to fuck HIM. And his dad was asking him to fulfill her wish. If only both of his parents had known just how much it had been his fantasy as well.
"Please baby, shove your fat cock up into my butt. Fuck your mother hard and deep in the ass," Jennifer whimpered, looking back over her shoulder at her son. He was teasing her by rubbing the purple helmet of his prick across her needy anus several times, further coating it with the slimy lubricant oozing out of his flared piss-hole.
Mark enjoyed watching how his practically begging mother was squeezing her anal muscles; making her sphincter contract and nip at his cock-head. It seemed to try catching his dome and drawing it into her bowels.
He looked at his wanton mother looking desperately at him through the shiny glasses on her face, and started pushing the head of his dick into her shitter. Slowly the wrinkled rim of her anus yielded, and allowed his leaking mushroom tip entrance. Once the greatest circumference of his prick-head was past the tight anal ring, the rest of it slipped inside easily until his mother's ass opening closed tightly behind it. It felt like the head of his fuck-stick had been caught in a searing hot vice. His mother really needed to relax her anal muscles if he was to go all the way in.
"GODDDD..." Jennifer wailed, a mixture of pleasure and stinging pain shooting from her asshole through her whole rump. She felt as if she had her son's fist in her ass, rather than merely his admittedly wide, purple cock helmet. Thank God for him at least wetting her anal orifice with spit and pre-cum, and for the fact that his shaft was of slightly less girth than his dickhead.
"Please move slowly, son," Jennifer groaned slowly feeling the pain subside and the pleasure of the fullness taking hold of her. "Take your time going deeper. Just, slowly move your lovely cock in and out to let me get used to feeling it slide around in my ass."
"Don't worry, mom," Mark put his mother at ease. "I want you to enjoy this as much as I do. I'll let you get used to my cock, and then I'll fuck your butt hard and make you beg me to slam it in and out of you."
Mark's words served both to relax his mother's nerves, as well as to get her back into feeling like a total, incestuous slut waiting for her very own son to relentlessly start hammering his cock into her shitter.
Slowly the 19 year old started moving his rod into his mother's back passage, the tightness of her anus around his shaft making it move inward with his tool until it was stretched inward to the max, after which Mark's pole would shove deeper into her ass canal, her sphincter moving further to the root of his dick. Just a half an inch, until Mark pulled back again, this time dragging the rim of her anus outward as it tightly clasped around his meat-stick. In again, and shoving an inch deeper than before. Out again. Slowly but surely, Mark was able to slide deeper into his mother's bowels, and simultaneously allowed her to get used to being filled up and stretched wide by the girth of her son's dick.
"Fuckkk... I feel so full. Your cock fills up my ass so good, son," the 39 year old mother croaked. "You can go a bit faster and deeper now, baby. You can fuck my ass faster and deeper now."
As Jennifer laid her head on the pillow, Mark grabbed the soft, warm globes of her butt tightly; kneading them and pulling them apart at the same time as he started fucking the tightly clasping hole in between with harder thrusts. The searing hot depths of his mother's anal caverns burned his dick with pleasure and the milking feeling of her ass chute around his rod making him feel as if being jerked off with a warm, soft glove.
Mark felt the hot, squeezing rim of her anus drag up and down along the surface of his shaft, as he poked his prick in and out into his mother's bowels deeper and deeper. Only an inch or two more until the root of his cock would be within her sphincter, and his balls would be pressing into the sensitive surface surrounding her butthole.
On hands and knees, panting and groaning in perverse delight, and her toes curling, Jennifer couldn't wait for her son to really start packing his meat into her dirt pipe relentlessly and quickly. Just the awesome feeling of having her ass stuffed and stretched to its limit with her own offspring's huge tool was enough to send nerve wracking shivers down her spine. She tried her best not to make her body convulse and thrash with the delightfulness of it. And when she finally felt the clammy, soft skin of Mark's ball sack press deliciously into the sensitive, stretched skin around her shit-opening, she knew he had tunneled his dick all the way into her ass orifice.
"FUCK YEAH," Jennifer squealed with the knowledge and feeling of being filled to the brim with family cock.
"Now fuck my butt really good and hard, baby," the passionate mother told her son with pure, incestuous lust in her eyes as she looked back at him over her shoulder. "Fuck mommy's ass hard and deep. Screw that fucking asshole. Screw my ass with your juicy, fat fucking cock. FUCK IT HARD"
"You want my cock fucking your hot ass, mom?" Mark asked rhetorically as he pushed and pulled his dong into his mother's buttery, gripping ass pipe with ever harder and faster lunges. "You want your own son fucking your hot, tight butt hard, deep and fast? You want to be your own son's filthy anal whore?"
"Oh God, yessss. I want to be my own son's anal whore. I don't want you to stop fucking me up the shitter, baby. Fuck mommy's asshole like it belongs to you to do with what you want. My ass is yours. Fuck your fucking fat cock up my butthole, son. Fuck it up there nice and deep. Fuck me, fuck me, fuck me..."
Enjoying the filthy dialogue between them almost as much as the actual incestuous buggering, Jennifer and her son let go of all the usual taboo inhibitions a mother and son have when speaking to each other. Whatever came to mind and seemed good enough to add even more fuel to the perverted, incestuous fire was good enough to say. Mark could feel his cock throb just from hearing his mother say those nasty things alone. And saying them certainly made Jennifer feel deliciously lewd, and nasty enough to contract the sheath of her ass even more tightly around her son's pile-driving pecker.
Fucking each other wasn't enough for the two of them. They had to convince each other just how much they really wanted it, by putting it into as filthy and descriptive words as possible and spit them out at each other.
Outside of the sexual activities they loved each other as any mother and son. But the moment they stepped into the realm of sex, they turned into a whole different kind of mother and son. But they were always mother and son. They loved each other as family when not having sex, and they lusted for each other as family when they were having sex.
The smacking sounds of Mark's hips into his mother's bubbling ass cheeks filled the room, in which Tim, Mark's father and Jennifer's husband, had been all but forgotten as he masturbated, being perfectly content in seeing his formerly estranged wife living out one of her deepest fantasies. He loved her more now than he ever did, and knowing that she now trusted him enough to admit to such a potentially disturbing fantasy made him feel nothing but warmth for her. In turn, Jennifer now knew just how much she really loved her husband, having been able to confide in him this secret and others, and finding him willing to help her live them out as well. With everything that had happened since they found each other's love and trust again, everything that had happened in the past couple of days, and everything that was said between herself and her son, she loved her husband more than life itself, and she would reward him in more ways than one for the rest of their shared lives for having given her this gift.
Jennifer felt the blood in her heated cheeks, almost searing heat, as her pucker was invaded by the girth and length of her son's prick with speedy and deep strokes. She felt his muscular arms wrap around her waist and the side of his head against her back, the sweat on both their bodies mingling. He was no longer behind her on his knees, but standing on his feet and almost crouching instead, fucking her ass from behind almost like a dog fucking a bitch in heat. His head moved back and forth obscenely as he pistoned his cock into his mother's shithole. Every now and then he would retract it completely, the purple helmet shaped head of his cock slipping out of Jennifer's lewdly gaping anus, before sliding it back in to his balls again. The mother had adjusted to the anal rogering where she knew how to relax her ass muscles, so her son had little problem shafting the full length of his cock in and out.
"Lay down on your stomach and spread you legs, mom," Mark ordered, and Jennifer complied. Loose strands of her brown hair matted to her sweaty neck and shoulders, she stretched out her legs and spread them wide, her toenails scraping along the sheet as she did, and laid down on her chest and belly, her tits squashed under her weight. Mark lay right on top of her back, his hips weighing down on her soft, sweaty buttocks, and used his legs to keep his mother's legs spread.
In this position he fucked down on her, his full balls slapping into the mattress as he continued pounding his cock into his mother's butt.
Jennifer liked this position too. Her tingling clit and oozing cunt were pressing into the soft sheets and she felt the full weight of her son's body on top of her. She could hardly move an inch as Mark kept filling her ass-snatch with his power-tool. His moist pubic bush rustled into and against the sweaty cleft of her ass and the hair on his balls slid along the open, drooling slit of her twat as they flew up and down with Mark's thrusting motions. The stretched rim of her asshole was burning lovely, scorched as it was by the fast movements of her son's fat dick meat. The position almost felt as if she was being ass-raped, but with her permission. She would return the favor later and rape him with her ass. Turn around is fair play.
"Goddamn it, yeah. Rape my asshole. Rape it. Fuck my fucking ass with your fat, raping cock," Jennifer whimpered with muffled voice into the pillow. Mark pounded into his mother's flattened body savagely, his hips moving up and down very fast, his loins slamming into her rump. He licked her shoulders and neck and bit softly into them as well.
Grabbing his mother around the waist, Mark lay on his side and pulled his mother with him, screwing his fucker into her hungry asshole in the spoon position. Jennifer wrapped her outer leg around her son's, arched her back and humped her butt back against her son as she felt his rock hard dick penetrate her sore anus with long strokes. With his arms around her, she turned her head and licked lewdly at her son's mouth. The desperate licks didn't go wasted on Mark, and he accepted his mother's warm, wet tongue between his lips, Frenching her as his hips continued smacking loudly into her ass from the rear.
After a minute of sweaty screwing, however, the 39 year old brunette noticed her boy was starting to have some trouble keeping up the pace, the muscles in his hips possibly cramping.
Rolling over so that her son was lying on his back, Jennifer lay on top of his chest with her back. Lifting her upper body up by planting her hands back on the mattress on either side of her son's body, the mother fucked her own ass onto her son's cock-stalk, rotating and humping her hips on top of his. Mark didn't have to move much this way, and allowed his mom to fuck herself on him.
He bent his knees while keeping his legs spread and his feet on the bed, and Jennifer planted a bare foot on top of each of her son's knees. Using her feet on her son's knees as a platform, she lifted her butt up and down from his hips, moving her own asshole up and down her son's fat shaft.
"Fuck yes. Now I'm raping you, Mark. Now your mother is raping you. Don't do anything. Just lay there and let mommy fuck her asshole up and down your fat fucking cock," Jennifer panted as her hips flew up and down on his; the tight, sucking warmth of her shit chute sliding over her son's thick, veiny pole.
Mark felt his mother's toes curl and dig into his knees as his prick was basically masturbated by his mother's moving asshole. Jennifer fucked her own shithole up and down over her son's upright hard-on, loving the feeling of the ridge of her son's cock-head sliding up and down on the inside, along the walls of her ass channel. She let the sucking sheath of her ass milk her son's dick as the movements of her body made her tits jiggle and forced the air from her lungs. She moved her right hand between her legs and shoved three fingers deep into her snatch. As her son's cock slid in and out of her butt, her three fingers slid in and out of the warm, wet, sucking depths of her cunt.
"Do you love it, baby? Do you love the way your mother is raping your cock with her ass? The way she is just using your delicious meat to fuck her own butt with? You love it, don't you? GOD, I love how your juicy dick feels in my asshole. I'm so fucking full with it. Your cock packs my shitter so full. Tell me how much you love it, Mark. Tell me how much you love feeling your mother fucking her own ass on your cock."
"You know I do, mom," responded Mark with a loud groan, feeling the cum boiling in his nuts. He didn't know much more he could take, but he would try to hold on a bit longer.
"You know I love feeling you fuck your own ass on my cock. I love everything. I love how your soft butt slams into my groin, how your tight sucking butthole clings to my shaft when you drag it up, and how it slides over my dick to the root when you push it down. I love how your toes are digging tightly into my knees because of how you feel in your ass. I don't think I've ever felt anything as hot and nasty and good as this, mom. I still can't believe we're doing this right now. I still can't believe you're sitting on top of me, with your hot asshole on my cock."
"Well, you better believe it, son, because this is no dream. Neither yours nor mine. You're really fucking your mother balls deep in her ass. Can you feel this?"
Jennifer takes Mark's cock into her ass to the balls, and then uses her sphincter muscles to squeeze tightly around his root of his cock.
"That is me, squeezing you to let you know this is really happening."
Mark was moving his hips now, fucking up at his mother's ass as Jennifer was still trying to move her own hips up and down as best she could. Mark's balls were swinging up and down, occasionally slapping up against his mother's leaking cunt. The ass fucking was savage now, with Mark seemingly trying to reach all the way to his mother's throat, and Jennifer trying to get it there. The movements became so wild and fast, Jennifer's feet slipped off her son's knees.
"Oh FUCKKK... That's it baby. Fuck your mother in the ass like a stud. Fuck my shithooooolleeee..." Jennifer whined loudly with a vibrating voice as the hammering of her son's cock into her rectum rammed the air from her lungs. The slapping sounds of Mark's pelvis pounding into his mother's butt cheeks filled the room to the point where maybe even the neighbors would be able to hear it if they listened carefully. But in this state neither Jennifer nor Mark could care less about anything other than their shameless, incestuous rutting.
"I want to see your face, mom," Mark said during a short lull in their movements. "I want to look you in the eyes when I fuck your hot shithole. I want to fuck you in the ass where I can see your tits, your cunt and your face."
Jennifer, liking the idea, climbed off of her son, - her lewdly gaping asshole slipping off of her son's prick -, and lay on her back. The 39 year old mother shamelessly raised her knees up as far as they would go toward her spongy tit-orbs, and spread her legs wide apart, opening up her crotch for her son to do with as he pleased. Her cunt-slit was leaking profusely and the thick, brown bush framing her labia and clit was matted against her skin. Her inflamed, red anal rim hung slightly open, worked out and waiting for more forceful penetration. Jennifer wrapped her arms around her legs to keep them up and apart as she watched her son take his place between her thighs, cock in hand.
As Mark settled the head of his cock inside the now slightly gaping butthole of his mother, Jennifer licked her lips and said: "Shove it in, son. Shove that fat fucker right back in, deep in mommy's asshole. Fuck it in me, baby. I want to feel you stretch my butt wide open again. Cornhole mommy, baby. Cornhole your mother. Ram my pucker with your juicy, fat fucking pole."
Mark loved hearing those nasty words coming from his mother's mouth. Hearing his own mother say things like that to him sent a nerve wracking shiver down his spine and almost forced his cock to swell and his pre-cum to drool right out of his piss-hole without any physical stimulation.
His mother wanted to act and talk like a common, cock hungry slut with him, her own son, and it made fucking her even hotter and better than it already would be without the aural stimulation.
"You want this fucker up your butthole, mom? You want your son's fat dick up your shitbox? Here it is, mom. Here you have your son's pecker, drilling right into your ass," Mark responded with broken voice, before entering his mother's ass and shoving the entirety of his cock into her ass passage to the hilt. He stopped to make her feel the full length and girth by keeping it up her back door to the root, his ball sack pressed flat against the crack of her ass, before he started humping against her and fucking his mother in the rear end with long but fast strokes.
He grabbed one of his mother's bare feet in each hand, almost using them as rowing ores, as he continued screwing her rectum.
Jennifer squeezed her soft tits as she and her son stared straight into each other's eyes, making a deep connection beyond the physical aspect of their depraved incestuous fucking. The mother deliberately milked her son's sliding fuck-rod with her anal muscles as their stare committed psychological incest. Not one shred of their whole being was being left out of the nature of their sexual activities, and to the degree that is was possible, the stare between mother and son's eyes was possibly more penetrating than Mark's cock into his mother's ass, and the nature of it possibly even more intimate.
Nothing but the creaking of the bed, and the panting of mother and son was heard for what seemed like hours, but were only minutes, until Jennifer softly spoke.
"I want you to cum in my ass. I want you to empty your balls inside your mother's ass. Please shoot your load up my butt, Mark. Shoot mommy's guts full of your cream."
The cum in his balls boiling, Mark heard his mother say it, and knew he could now drop his load. His mother had asked for it, and he had a hard time keeping up this long as it was.
He let go of any restraints he had put on himself and the tempo of his movements, and just screwed into his mother's tightly clasping anus without slowing down. The sucking of his mother's ass-tube around his dick helped make a delicious warmth spread over his loins and through his pecker, and the 19 year old knew he was about a second away from blowing his wad.
"I'm cumming, mom. I'm cumming right up your ass. Here it comes. I'm gonna shoot my load up your aaaaaaaass... GOOOODDDD... FUUUCCCKKK... MOOOOOMMMMM"
Mark's loins spasm'd as waves of hot jizz were shot into his mother's bowels. Jennifer curled her toes in her son's hands and she felt torrents of her son's warm spunk shoot up her ass pipe. She used her own fingers on her clit and cunt to bring herself to an orgasm as her darling son used the deep pocket of her rectum as a cum receptacle.
"Babyyyyy... Cum in mommy's aaassss... Oh God, yeahhh... Shoot your hot spunk up my guts, son. I'm cumminggg... MOMMY'S CUMMIIIIIINNNGGGG..."
And from that point on, no more words were said. Mark and Jennifer were both limited to cries and whimpers of joy, as they each climaxed while locked into and onto each other's bodies. Mother and son had now enjoyed the most intimate sex between them they could think of.
Jennifer had given her ass to her son, and in the back of their minds they remembered that his father, her husband, had been a silent and willing spectator to it.
As Mark finished emptying his balls into Jennifer's back hole, and was now lying on top of his mother with the both of them panting and sweating, enjoying the bliss of the aftermath, both mother and son knew that as much as they had enjoyed this newfound relationship beyond the ordinary mother and son relationships most mothers and sons share, they had Tim to think for all of it.
After everything that had happened over the past couple of days, Jennifer knew that despite the problems she and Tim have had in the past, she ended up finding out that she really did marry her soul mate.
Their family would never be the same. But Tim, Jennifer and Mark wouldn't want it any other way.
Now the only thing for them to worry about, was how to keep their new, special relationship a secret from Tim and Jennifer's daughter, Mark's sister.
