Helen put some of sandwiches in a tupperware box and grabbed a couple of cans of soda before heading out to the beach. As she approached and noticed Dan swimming along the shore, she slowed her walk down into a sexy saunter, swinging her flared hips with every step. It didn't take long for Dan to spot her and he stood up, the water reaching his shoulders. Seeing she had her audience, Helen threw her chest out a little and started to swish her tail left and right with each step.
                She imagined what she must look like to the boy, her already impressive cleavage barely restrained by her bikini top, the white material almost blending with the creamy fur on her chest as she strode across the sand on long, toned legs. A hell of a sight, especially considering the boy had just watched a home video of her pegging his mom. He was frozen in place and Helen was surprised the water didn't start steaming off him.
                "Dan sweetie, I brought you some sandwiches in case you got hungry!" she shouted, breaking the boy from his trance.
                "T-thanks Ms. Paige!" Dan called back, looking away and hoping the vixen didn't catch him staring. 
                This will be easier than I thought! thought Helen who did catch the boy staring, and who made sure he had something to stare at. She noticed the boy's beach towel spread under a nearby parasol and decided to roll hers out next to it. She put the food and drink down in the shade and settled down for a nice nap on the beach. Or so it seemed. Truth be told, even though she and Lydia, Dan's mother, had gotten pretty frisky on the beach earlier, she still had plenty of energy left and was too excited to sleep. So she just closed her eyes and stretched out on the towel, hands behind her head, her glorious breasts on full display and threatening to spill out of her top.
                Several minutes later she heard Dan get out of the water and make his way to the shade, being quiet so as not to wake the seemingly sleeping vixen. She heard the boy tear into the sandwiches, having forgotten to have breakfast earlier. Helen let him eat in peace, her motherly side reminding her how important breakfast is to a growing boy. After he was done, still sitting beside her and resting, her sexual side reminded her it was time to get the show started and see just how much they could make the boy grow.
                She started with a low, drowsy murmur to get the boy's attention and shifted her sinuous form slightly in a way she knew would keep it. In her mind she did her best to work herself up, imagining the things she would do with the boy once he's seduced. She pictured herself letting him inside her, taking his virginity and as the cute kit thrust himself into her depths, taking his seed as well. This had desired effect, and as she rubbed her thighs together she felt herself getting wet and knowing the stain would soon be clearly visible as it soaked into her white bikini bottom.
Picking up the pace the vixen turned in her 'sleep', facing away from the boy. She curled up into a fetal position, which gave Dan a great look at her round ass and curvy thighs, not to mention a wet patch on Helen's bikini bottoms that outlined her plump pussy.
"Mmmm, Dan..." Helen moaned softly, knowing what this would do to the boy. Sure enough, after waiting to make sure the vixen wasn't waking up, she heard rustling noises as the kit reached into his swim trunks.
Dan couldn't believe his eyes. Or his ears for that matter! Here was this gorgeous, sleeping vixen soaking her panties as she had a wet dream about him! His hand reached into his trunks almost without him thinking about it and started stroking his adolescent sheath as he contemplated the sinuous ball fur in front of him. He got on his hands and knees, curious about the moist patch on her bikini and brought his nose closer to Helen's lips, now visible through the taught, wet fabric. He took one good sniff and shuddered as the pheromones of a vixen in heat hit his young brain. Slipping his swim trunks hallway down his thighs he grabbed his by now erect cock and started stroking it, all the while inhaling that scent, as the vixen in front of him moaned in her sleep.
Helen heard the rhythmic sounds the panting boy was making and decided to spring to action. She rolled over and drowsily opened her eyes, catching sight of the panicked teen trying to pull his trunks over his exposed erection while kneeling next to her. Bingo!
"Oh my God, Dan! What do you think you're doing!?" she shouted at the boy in fake outrage.
"I'm so sorry Mrs. Paige! I just came over to get a sandwich and then I heard you... uh...." Dan trailed off, too embarrassed to tell the vixen she'd called out his name in her sleep.
"Have I been... talking in my sleep?" I would like to thank the Academy...
"I... thought I heard you say 'Dan'..." the kit mumbled, unable to look Helen in the eye.
"Oh. Well I suppose it's not your fault. At your age it's probably hard enough to control your urges without a woman in a bikini calling your name out in her sleep."
"I didn't mean to. It's just that... " Dan almost said something along the lines of ' after seeing you in that video' but managed to catch himself in time "... you're very beautiful."
"You think so?" she said sitting up to face him, her arms planted on the ground in front of her, squeezing her boobs between them.
"U-huh..." was all Dan could get out of his mouth, his gaze glued to the perfectly framed cleavage in front of him.
"Dan?" Helen said softly, but loud enough to bring the kit's gaze back upwards. "Have you ever kissed a girl?"
"No?" Dan wasn't sure how to respond, his best friend's mom now looking and talking at him in a completely different way. He was sure he was going to get into trouble when she woke up, and he supposed he still might, but it was now turning out to be a much better kind of trouble.
Hellen took the boy's chin in her hand and brought her lips to his. As she kissed him she felt him tense up for a second before he relaxed and started kissing her back, lacking any experience, but not enthusiasm. As he tentatively slid his tongue inside her mouth, the vixen ran one hand along his shoulder and then his chest, encouraging the boy to explore her. With all the shyness and single-mindedness of an adolescent, Dan reached out and gently brushed her fingers over her breast. 
Helen moaned into their kiss. The boy's touch was not deft enough to make her moan, but she wanted to encourage him. It seemed to work, Dan becoming confident enough to cup her globe and give it a gentle squeeze through the fabric of her swimsuit. This reminded Helen that she was a bit overdressed for what was to come. She gently broke their kiss, giving the boy a demure but sensuous look, noting the dazed expression on the kit's flushed face.
"Would you like to see them?" she asked coyly, looking down at Dan's hand still glued to her teat.
"Y-yes?" the kit responded to what seemed at this point an entirely rhetorical question.
Helen slipped off her top and arched her back slightly, to hit the boy with the full force of her cleavage. Dan's mouth actually hung open as his eyes focused on the vixen's perfect mounds, the heavy orbs having just the right amount of sag. They rose majestically out of the vixen's fluffy, cream colored chest fur, each topped with a pink areola, the nipples stiff and inviting. Dan reached out, looking up at Helen and seeing her approving expression touched a hand to each breast, the soft orbs filling his palms as he cupped them.
The vixen let out a contented sigh, encouraging the kit to knead her tits gently. She was genuinely enjoying this part - her breasts have always been very sensitive and the boy seemed to be a natural, caressing her boobs and every now and again running his thumbs over her perky nipples. She closed her eyes and let herself savor this bit of intimacy before her seduction of the boy reached it's grand finale.
Helen let out a gasp as she felt a tongue flick over one of her nubs, and looked down into Dan's eyes, his muzzle at the tip of one breast as he looked to her for approval. She put her hand on the back of his head and guided his mouth to her nipple, moaning earnestly as the boy started to kiss and suckle on the pert tip, his hands still caressing her tender globes. Oh God, I missed this! she thought, regretting she had no milk for the eager little kit. She had loved the sensation of a little muzzle nursing from her teat and had breastfed Terry until he was four, enjoying the closeness and intimacy of her little kit curled up on her bed next to her suckling on a pink nipple as she cooed at him and ran her fingers through his hair. That would be another thing to look forward to, when the baby arrives. It also occurred to her that Lydia would be lactating at the same time, and she allowed herself to get lost in the fantasy of the two of them in a slightly different sixty-nine, each vixen nursing and suckling her lover.
But first she would have to make the baby. One glance at the boy's shinny red rod told her that he was ready, and she was sure she was going to have to peel her bikini bottom off. With some reluctance, she pulled the boy off her breast and angling his chin upwards gave him her best bedroom eyes.
"Do you want me?" she husked, certain that she was an offer the boy couldn't refuse.
The kit could only nod, eyes glued to the vixen's as she seemed to drag him up with nothing but a finger under his chin. Helen turned around and hooked her fingers through the sides of her bikini. She slid the soaked garment down her legs while bending over and raising her tail, giving Dan the perfect view of her lush heart-shaped ass, as well as her glistening slit. The boy's attempts at disrobing were not as impressive, and he almost fell over in his rush to get his swimsuit off. As she turned around, Helen got a good look at the kit's now fully erect member. She was pleasantly surprised, the boy's cock must have been 6 inches from tip to base, his knot still looking like just a slight bulge as he leaked pre from the tip. She thought about having a taste, but decided not to. She was sure Dan had emptied at least one load during or after watching the video of her and Lydia, and whatever was left inside that cute little pouch between his legs was going between her other lips.
She bent over and gave the boy a brief kiss before lying down on the beach towel, her legs spread and her moist pussy on full display for the kit. Dan knelt in front of her as if in a dream, his eyes locked on the vixen's quim, the smell of hear heat making his head swim. He brought the tip of his shaft to her entrance and looked up at her. Helen gazed back through lidded eyes, her cheeks flushed and her lips parted, giving him an unmistakable 'Fuck me!' look as she guided his young member to her eager pussy.
Dan lowered himself over the gorgeous vixen as he slid inside her, gasping as he felt her warm tunnel wrap itself around his shaft as it shot a few spurts of pre into her already sopping depths. He felt her breasts flatten against his chest, her still stiff nipples rubbing against his fur. He pushed further, until he felt his crotch bump against the older vixens and just stayed still, trying to get used to the amazing feeling of her tunnel squeezing his immature member. He felt Helen's arms wrap around him, holding him closer as the vixen passionately kissed him.
Helen was surprised by how turned on she was. The boy was smaller than the toys she and Lydia used, but the feeling of a live, warm shaft throbbing and leaking inside her made up for it. The kit's innocence, combined with her heat, brought out the mother in her as she held him close to her while they kissed. The boy had just given her his virginity, and in return she would let him set the pace of their lovemaking.
He didn't make her wait long before he started pulling out slightly, his knot now plumper but still sliding out with ease before pushing back as deep as he could go. She moaned earnestly into the kiss, their combined juices leaking out of her and soaking down into the crack of her ass as the kit gently pumped her cunny. Helen felt her heart beat faster as she allowed the bliss of the mating to wash over her, her legs splaying even more as her body showed it's desperate need to be bred.
Dan reluctantly broke their kiss, but the panting kit needed air as he sped up his thrusts, now pulling out almost all the way out before sheathing himself in Helen's pussy. He still couldn't believe his luck as he looked down at the blushing face of the vixen underneath him, letting out small yips and gasps every time he lunged into her, the feminine noises triggering masculine instincts deep inside his brain and filling him with no small amount of pride. Only yesterday Helen had been his best friend's mother, an untouchable beauty that looked at him as a child. Now that same beauty was writhing under him, looking up at him as her lover as his young shaft invaded her depths.
Between pants Helen heard herself moan encouragements to the boy, spurring him on as the heat in her loins made her desperate for every inch of his malehood. Looking behind him she could see his tail wave and his little but rise and fall every time he humped into her, wet squelching sounds accompanying every lunge. His knot was now formed, bumping against her lips every time he thrust and tugging on her sex with delicious agony every time he pulled out. She met his gaze and saw the question in his eyes, his brief display of sexual dominance pushed aside as the kid inside him asked the older vixen for permission.
"Do it sweetie... tie me!" she panted.
The kit didn't need more urging and as he lunged inside her Helen she clenched her muscles around the rod buried in her as her legs wrapped around the boy's waist. The vixen held him firmly against her, panting as Dan's knot swelled rapidly, tying the kit with his lover. She lay there, feeling Dan's heart thudding in his chest, her pussy feeling his pulse as it stretched around the bulbous knot. She had no idea how long they stayed like that, and even though a part of her was loathe to see this perfect moment end, there was an itch deep inside her demanding to be scratched.
"C'mon baby, do it... it's OK..." she whispered the kit's ear as he nuzzled her neck.
Those were the words Dan was waiting to hear as he desperately tried to hold back his climax. He gave Helen's shoulder a little possessive nip as he humped into her with very short, rapid thrusts. The dominant masculine display was somewhat spoiled a little later when he let out a boyish 'Eep!' as he felt his cock shoot load after load of seed inside his mate. The vixen let out a long moan as she gripped him even tighter, almost crushing him to her as her pussy spasmed around him, milking his cock of every drop.
When the boy's first spurt splashed against her cervix, Helen felt her climax wash over her. She wrapped herself around her lover, holding him tight while his young shaft put out the fire burning deep inside her. She moaned as she felt his seed flood her fertile womb, the kit's knot keeping every drop inside her as his warmth spread through her, replacing her heat. Her hold on the boy became less urgent and she relaxed as she held him in her arms while they shared the afterglow, his first one ever. She knew she had seduced him and taken his virginity, but she had no regrets and was sure he wouldn't have any either. She made sure his first time was gentle and loving, and with someone who cared for him deeply. As she kissed the top of the exhausted kit's head, she wondered what her own sons first time will be like...
