COMMISSION: BETH AND SAMMY in:
Teaching Her Son For His Birthday 2

by OttersInTrousers

-----

Beth's heat continues, and she and her son, Sammy, spend his seventh birthday and the next days after enjoying one another's bodies.

It is late Sunday morning when Beth finally wakes, the chubby golden retriever woman slowly shifting and stretching out as her body returns to wakefulness. This is the latest she has slept in since—she doesn't even know. Probably since before Sammy was born, maybe during university, when she was free to stay up as deep into the night and stay in bed as late into the day as she wanted. The alarm clock on her bedside table reads 10:52. It's nearly lunchtime!

She expects the long-familiar sensation of her heat raging in her womb, the longing and the hormones and the itch she can't scratch herself. But instead, she is greeted by sore muscles and a pleasant ache in her vagina, a warmth pooled deep inside it. A weight rests between her thighs, over her soft belly, and between her breasts.

It's Sammy.

Sammy, Beth's son, is seven years old today. She allows herself a moment to reminisce about the past two days.

-----

Friday night, after a day of her heat building and building, Beth and Sammy watched a movie together—except he picked it out, and he accidentally chose something a little more adult than either of them expected. After watching the stars onscreen having oral sex, Beth couldn't really take it anymore, and she got her own pup to eat her out, then went down on him. They ended up mating right there on the couch.

Saturday was at once pleasant and tense—sex with Sammy the night before had soothed her heat, and she drifted on that high for a time, but the guilt, the uncertainty, hung over her. That night, as the discomfort of her heat returned, she resolved to do it again, nominally as a gift for his birthday and to teach him about sex and sexuality, but just as much to sooth herself and “treat” her heat. They fell asleep together after.

-----

Beth's thoughts return to the present. Now that she thinks about it, the warmth against her cervix feels fresh. Perhaps Sammy had a wet dream? It's unlikely he managed to have his way with her—and then fall back asleep—without waking her up. But now the thought of that is getting her excited—her little pup, so enticed by her scent and his nascent sexuality that he ruts her while she is asleep. She holds back a moan. She needs to wake him up before she gets too aroused.

Beth runs one hand through the golden-blonde fur of Sammy's back, petting him gently, and calls his name in a whisper.

“Sammy.” She smiles when he nuzzles deeper against her big, soft breast. “Sammy, baby it's time to wake up.”

Sammy groans a little, quietly, as he tenses up and stretches out atop her, giving a few unconscious humps of his hard little penis into her spade. Then he freezes. His eyes shoot open and he pushes himself up in a rush.

“Morning, Mama!” He looks between them, at their nude bodies, eyes darting between her boobs, over her belly, down to her spade, his smile growing all the while.

“Good morning, baby. Happy birthday.”

“Can we mate again?” He looks back up to her face, ears perked and tail a blur.

“Of course, Sammy.” She chuckles when he gives a couple of enthusiastic little humps in his glee. “Anytime you want, you can mate me.”

He sets to work immediately.

And she just lies there, basking in it—

His golden-blonde fur mingling with hers. The wet warmth blooming inside her vagina and filling her. His ragged breaths huffing against her. Her own breath raising and lowering him with her belly. His voice as he moans out, “Mama.” His hands holding onto her breasts like a lifeline. His tail sweeping back and forth against the sheet overtop them. Their scents and the smell of heat and sex filling her nose. The taste of him on her lips. She feels like she has become addicted to him—to sex with him. She needs more. And he gives her more.

With a grunt and a final thrust that sends his puppy knot between her puffy outer lips and into her passage, Sammy climaxes, pumping another fresh load of his cub cum right into his mother's vagina.

Beth sighs a pleased moan as she feels him spurt into her. She doesn't even orgasm—the previous load already in her when she woke has soothed her enough that another so soon doesn't push her over the edge—but she doesn't need to. This is enough, just being with her pup, letting him fill her up, feeling his pleasure in her. For a few minutes, Beth pets over his back as he winds down, panting between her breasts.

When he finishes catching his breath, he starts right up again, still hard and knot still engorged. Beth isn't quite sure how to feel about that. On the one paw, with his knot, it's far more stimulation than just his little cock alone—she can't help the repeated moans as the bulb grinds in against her g-spot and brings her to her first orgasm of the day. On the other paw, him not leaving the knot in—even though it's much too small to truly tie her anyway—feels tantamount to sin. As good as it feels to be knot-fucked, her body screams that it needs to be inside, it needs to stay inside, fill her up, not let any run out, hold it all in until she's good and bred.

“Sammy,” she starts, unable to help the ecstatic moan she follows it with. When he grunts his acknowledgment, she continues. “Remember what I told you yesterday, about your knot?” She gets a quiet mhm between huffs. “Well, it feels really good, what you're doing now, but just keep in mind, I need you to leave it in when you finish this time, okay? Mama needs it all inside her.”

“Okay, Mama.” Between breaths, he explains himself. “I just—I really wanted to do it again. And I didn't wanna wait. I love you, Mama.”

“I love you too, Sammy.”

When he cums again, he makes sure to press in all the way, and leave himself in until he finishes. For her part, Beth clenches down tight around his little cock, wraps him up in her arms and legs to make sure he stays right where he belongs, and coos appreciatively.

-----

The day ends up being one very long marathon of sex. Over and over, Beth guides her pup through mating her, encourages him to take her as many times as he wants. In the afternoon, she brings him back to her room and teaches him how to do it Doggy Style.

At first, Sammy titters at the name and its implications. But once she gets on her hands and knees in front of him and presents herself to him, and he gets started, he seems to rather enjoy it—Beth sure does. It's an exciting change of pace, and the way he handles her body is different, too. His thrusts come in extra-hard, slamming in with more force than he has been able to before, hips slapping against Beth's soft butt. He lays himself over her back, head resting against her shoulder blades. His hands, so small, explore the new facets of her body on display in this position—grasping as her sides, sliding down to hug at her belly as it jiggles with the force of his humping, groping at her big hanging breasts as they swing below her and clap against one another and her belly.

It's maddening, in a perfect way.

“Mama, I'm gonna—” Sammy cuts himself off with a grunt as he jams his knot in, still too small to really stick, but enough to be felt, enough to be right. He squeezes her breasts, her nipples hard against his palms.

“That's it, Sammy,” Beth coos as the first spurt of his cum enters her and she joins him in climax. “Let it go. Let it all go in Mama.” She hums her approval as he presses in just that tiny bit tighter, little sheath flush with her spade, little balls against her clit.

After they finish, when his little cock softens and falls from her spade and he tumbles to the side to recover, she kisses his snout and pets over his head, then rises from the bed.

“Love you, baby. You take as long as you need to catch your breath. I'm gonna go start on dinner, okay?”

Sammy smiles in her general direction, still so blissed out he can hardly move.

“Okay, Mama. Love you, too.”

Beth pads out of the bedroom still nude, enjoying the feeling of air across her bare fur as she makes her way to the kitchen. There, she decides to have a bit of fun, and dons her apron—and only her apron—before starting on preparing Sammy's birthday dinner.

Nearly twenty minutes into cooking, with her tail wagging and the feel of her cub's cum oozing slowly from her spade, she finally hears the bedroom door open. Her tail accelerates.

“Hey Mama—” he freezes in the doorway.

Beth chances a glance over her shoulder to find him back in his pajamas, tent straining his shorts, staring unabashedly at her bare ass. She smirks and sets down the spoon.

“Hi, Sammy. You feeling okay?” She turns to face him, putting just a little extra force to the turn so one tit spills out to the side of the apron to sag outwards. She can't help but giggle at the way he gasps. “There's my good boy.” She approaches, breast still bouncing free, to lean down in front of him. “What do you think of my outfit, baby?”

Sammy takes a comically thick swallow of the drool that has gathered in his mouth, then pants.

“Mama. I could—” he glances down, then back up to her eyes. “I could see your cookie.” One hand half-raises, and his eyes trail back down to her hanging nipple. “And your boobie is—out.”

“It's okay, Sammy.” She takes his hand, guides it up to grasp at her breast where he immediately squeezes. “You can touch it. What do you think of my outfit? Is it sexy?”

He flushes red enough she can see it through his fur.

“Y-yes,” he stutters out, then nods. “I really like it. It's—sexy.”

“Well,” Beth begins, smiling at the flustered mess he's become, “once we finish dinner, we can mate again. Until then, you look just as much as you want, okay?” She straightens back up, fixes the apron back over her breast, then returns to the stovetop.

As she finishes cooking, Sammy moves around the kitchen, setting their places on the table. All the while, she can feel his eyes all over her body, especially between her legs. She makes sure to keep her tail up for him, to stick her ass out, to bend over, all to give him a better view of the pussy he fucked only moments ago.

-----

She has just climbed into bed, pussy still painted by the load she got while tucking him in and wishing him a goodnight, when she hears him approach her doorway. She listens as, after a moment of hesitation, he opens the door and pads in.

“Hi, Sammy,” she calls out. “Having trouble sleeping, baby?”

“Hi, Mama.” He shifts from one paw to the other. “I wanna sleep with you tonight. Can I?”

She looks him over, eyes pleading and hands held together. Already, the bulge in his underwear hints that his penis is peaking its way from its sheath. She smiles reassuringly at him.

“Of course, Sammy.” She tosses the side of her covers back for him. “Come on in.”

He starts to climb up, then stops and steps back, only to tear his clothes off. Once fully nude, he clambers up on her bed and scoots right to her side and wraps his arm around her soft belly, his bare fur against her own.

“You're naked, too, Mama?” His voice is awed.

“Mhm. Mama likes to sleep naked sometimes.”

He hums a reply, nodding against her breast.

“I wanna—” he's interrupted by a yawn, “—mate again, Mama, but I'm real tired.”

“Aw that's okay, honey. Mating doesn't have to be quite so energetic as we have been. How about we cuddle? Come here.” She helps guide him over on top of her and into position. He slips his little cock right in. “There you go. Now, we can just lie here. You're inside me, and that feels good, right?”

“Mhm.”

“And anything we do will feel good, too. We can pet each other, or nuzzle each other, or just give slow, gentle thrusts.” As he follows along to her suggestions, she pets his head appreciatively. “There you go, Sammy. Soft and slow. What a good boy.”

And he does take it slow. For a little over ten minutes, he slowly gyrates his hips against hers, punctuated by the occasional hump. He coos and sucks at her nipples, one then the other, and all the while she lies beneath him, delighting in the feel of her pup inside her, mating her. When he comes, it's as gentle as their cuddlefuck has been—he gives a quiet grunt, then sighs against Beth's breast as his little cock twitches inside her then spills a fresh load of cum into her. He's asleep before he even finishes.

-----

“Aww, Mama, do I have to go to school?” Sammy whines this question with his head on the kitchen table, empty breakfast plate pushed aside.

Beth can't help her smile, but does her best to hide it.

“Yes, Sammy, you have to go to school.” She pets his head, then picks up his plate. “It's the day after your birthday, don't you want to see your friends?”

“I guess, but I wanna stay home with you more.”

“I know, honey. I'll miss you too, while you're gone, but I'll be here waiting for you when you get back, and we can mate again just as soon as you're home.”

“Promise?” He looks up at her with his best puppy eyes, pleading. She could never refuse this face, even if she wanted to.

“I promise. Now go get ready, or you'll be late.”

-----

Beth hadn't really considered how much she would miss him. His scent hangs in the air, in everything, all over the house. And her heat—well, fucking last night helped, but it's still there, she still needs. The day moves at a crawl.

When Sammy steps through the front door, wiping his paws on the mat, Beth charges him.

“Sammy! Welcome home. How was school?” She practically throws herself into him to get a hug.

“Mama!” He hugs her back, just as enthusiastic. “School was okay, but I missed you.”

“I missed you too, honey.” Beth freezes. He smells—she sniffs him a couple times. He smells too much like other things—the school, his classmates, the dirt in his clothes and fur from recess. She grimaces and holds him at arm length.

“What's wrong, Mama?”

“Well, you know how Mama's in heat?” He nods, so she continues. “Well, Mama's nose is a little extra-strong because of it, and you smell like—well, a lot of things. And it's kind of overwhelming.”

“Oh.”

“Think you can get a bath now, then we can catch up?”

“Okay!” He drops his backpack and sprints for the bathroom, not even stopping by his bedroom for a change of clothes.

Beth sighs and shakes her head with a chuckle. After fetching him some pajamas, she lets herself into the bathroom to leave them for him, but stops herself—he's probably already gotten the worst of the smell out, she could join him. With shaky paws, she tugs her sweater up over her head and fumbles with her bra clasp before dropping both to the floor. Then she tugs her pants and panties down at the same time—her panties stick to her puffy spade and peel away awkwardly. She bites back a moan at the feeling of being naked—exposed—again. She delicately runs a finger over her plump lips.

It feels so good to be naked. She hadn't really had time to bother with clothes on Sunday, with all the nonstop sex she and Sammy were having, but today she got fully dressed, and it was a lot to deal with, being fully clothed while in heat. Now, fur bare and pussy out, she feels so much more comfortable, so much more sexy. She can feel the arousal drip from her cookie. She may just have to dress more lightly tomorrow. She's sure Sammy will appreciate a better look at his Mama's body, too.

Sammy.

She turns her attention from herself back to the shower, where she can hear the pup humming a little song as he cleans himself. Through the frosted glass of the door, she can just make out the vague shapes of her pup, tail wagging as he shampoos.

“Sammy,” she calls from across the room, “I brought you some Pjs.” She approaches the shower door.

“Thanks, Mama! I kinda forgo—” 

Sammy trails off when Beth slides open the door and steps in with him. His eyes go round as saucers, trailing up and down her nude body as the water begins soaking into her fur.

“Hope you don't mind, honey, but I thought maybe I could help.”

That seems to snap him out of it.

“Uh, no Mama, I don't mind.” He shifts back and forth on his feet, then steps forward to hug her. “I missed you Mama. I missed doing—sexy stuff. Mating.”

“Awww, I missed you too, Sammy.” She wraps him up in her arms and squishes him against her soft belly. Dropping her voice to a husky whisper barely audible over the shower, she continues. “And I missed mating, too. I'm really in the mood already just thinking about it.”

Sammy giggles his excitement.

A few minutes pass while Beth helps Sammy with his shower, her wandering hands occasionally dipping down to cup his little balls or stroke his little erection.

“Mama,” he says as he watches the last of the suds slip down the drain, “I wanna mate you.” He looks up at her to add, “right now.”

Beth smiles down at her sweet boy, so precious and eager. Then she leans back against the shower wall, legs parted.

“Okay, baby. Come here.”

He practically throws himself into her, nuzzling up into her breasts, and—his cock bobs between her thighs. He's too short to do it standing like this, of course he is.

“Oh, looks like—hmmm.” Beth shifts down, bending her legs while Sammy stretches up on his pawtoes and that just barely brings his tip to her entrance. There's just no way. “I don't think we're gonna fit like this.” She strokes down his back as she considers her options, before remembering. “The stool! Sammy, run and grab your step-stool from the kitchen.”

He's gone in an instant, trailing water along behind him, his claws clacking on the floor as he sprints off. She chuckles. He's back a moment later with the little stool they keep in the kitchen so he can reach the countertops while helping her cook. The smile on his face is so bright it's like looking at the sun.

“I got it, Mama!”

She helps him place it in the shower, then he steps up onto it. It perfectly aligns them, his little penis now pressed up against her vulva.

“I'm gonna put it in now, Mama.”

Beth sighs her relief to the ceiling when her pup hilts her in the first stroke.

“Oh, Sammy, Mama needed this.”

He really gives it to her, which has her more than thankful the stool has rubber feet to keep it from sliding. His hips jackhammer into her, sending her into an early orgasm. She howls up at the shower ceiling as she feels herself clench down on him, squirt around his little cock into his pubic fur. He doesn't slow down.

He just keeps slamming in, growling with the effort of it. As she works her way down from her first orgasm, he nuzzles into her breast, first licking and then sucking at her nipple.

“Mama,” he grunts into her tit, “I missed you so much today.” His hips are a blur. Beth's pussy clenches. “I missed you. I missed the way you smell.” He nuzzles in again, and Beth feels herself approaching another orgasm, so soon after the first. “I missed mating youuuu,” he holds the last syllable out as he gives several especially enthusiastic humps into her, driving his burgeoning knot in and sending Beth tumbling into a second climax. “I missed squirting inside you!”

She feels it.

He falls completely still, sheath against her spade and knot wedged inside her, teeth clamping down and tugging on her nipple, when he cums.

Beth's orgasms come so rapidly, so close together, that she doesn't so much experience multiple consecutive orgasms as she has one very long, continuous, mind-blowing climax. She forgets to breathe for a moment.

There's so much—or at least, she thinks there is. It's hard to be sure, with the water diluting everything and washing it all away, but it feels like he's cumming far more than his usual production of a few little squirts. Maybe it's wishful thinking. Maybe it's the brain-meltingly good orgasm she's experiencing.

-----

After they finish both the sex and the shower, and Beth has made sure Sammy's fully dry, he puts on the pajamas she brought him—an oversized shirt and pair of briefs. Beth follows after him, wearing nothing but a towel.

As she fills a glass with water in the kitchen, she hears Sammy pad up behind her. Her tail raises and wags, lifting the back of the towel with it and exposing her rear to him. Though she has no proof, she imagines there's no way he can't see her spade right now.

“Mama?”

“Yes, Sammy?”

“Is that all you're gonna wear tonight?”

“For now, baby. In a little bit I'll put on my robe.” She hears him sniffing at the air. “Why, is there something wrong?” She smirks around the rim of the glass.

“No!” His reply comes lightning-quick. “I like it. It just—it makes me wanna—” he hesitates.

“Makes you wanna what, Sammy?” She finally turns around, and finds him with his underwear down at his ankles, hand grasping his penis where it's already free of his sheath.

“M-mate. It makes me wanna mate you again.”

“Remember what I said Sunday morning?” She approaches him, bending down to give him a good view of her fluffy cleavage. “Anytime you want, baby, you can mate me.”

“Mhm.” He nods, but his eyes don't leave her breasts. “I wanna—” he reaches up. His hand hesitates, then he tugs at where she's tucked the towel, freeing it from her body and sending her big boobs drooping free to clap quietly against one another.

Beth moans.

“That's it, Sammy, good boy. Here,” she takes hold of his hand, still in the air between them, and guides it to her breast. 

As he toys with her nipple, he continues jerking off.

“Let's go to bed, baby, so we can mate properly, okay?”

“Okay, Mama!”

-----

Somehow, Tuesday is even worse than Monday. Beth doesn't understand it—she even had him give her one more load right before school this morning. Yet here she is, barely 10am and desperate for the relief of having Sammy's cum, the pleasure and comfort of his little body pressed against hers. She's spent the morning listless, wandering the house aimlessly, fingering herself off and on. Beth growls. This just isn't enough—it can't be enough. She needs more than just what she can get in the evenings and mornings. She needs little Sammy here, inside her, taking care of her, filling her up with his semen, bringing her to orgasm after orgasm.

Beth comes to a startling realization. She can just check him out of school for the rest of the week.  There's nothing to stop her. Sammy's a healthy boy, he's rarely absent, he does well on all his schoolwork, he can afford to miss three days in order to fulfill his role as her son and mate. He already didn't want to go anyway. She hurries into clothes.

-----

When they get home, Beth guides Sammy directly to the shower. After they finish, and she slips on the same blue nightgown she was wearing when this all began, she turns to her pup.

“Sammy, since it's not a school night anymore, want to watch another movie?”

He perks up, ears forward and tail wagging.

“Yeah!”

She watches as he shoots off to the living room. By the time she gets there, he's already got the movie ready, sitting on the couch waiting for her. She joins him, sitting right beside him and pulling him into her side. He sighs against her breast, then wraps his arm around her belly.

A few minutes into the movie—a recent animated film that seems like the perfect blend of silly and heartfelt to have Beth invested, too—Beth notices that Sammy's hand is drifting down her belly. Down, down it goes, sliding over the satiny fabric of her gown until it lands in her lap. There, she watches and feels as his fingers gather up the extra fabric over her legs until he's grasping the hem, then he dips his hand between her thighs.

She can't help the moan when Sammy's fingers brush against her spade, breaking the silence between them. Sammy giggles.

“What are you up to, Sammy?” Beth runs her hand through the fur on his scalp as she asks.

“I wanna mate again.”

“Okay, we can—” 

“But I don't wanna stop the movie.”

Beth hums in thought.  “Well, I think I have an idea. Remember the very first time we mated?”

“After I licked you, and then you sucked on me?” He's looking at her again, excitement and arousal evident.

“Mhm.”

“You laid down, and then—oh! If we're laying down like that, I could still watch while I mate you!”

“That's right, baby. Such a clever boy.” She pets his head, and his tail wags. “Hop up.”

They both stand, and she quickly shucks her nightgown, setting it on the back of the couch, before she lays herself down along the couch, shuffling a bit to get comfortable with her head against the arm. Once she's settled, she holds her arms out for him. Somehow, he's already managed to strip himself naked, and hops right up between her legs, settling in against her.

“I love you, Mama.”

“I love you too, Sammy.”

He presses his little cock in.

With his head pillowed on her breast and turned to keep watching the movie, Sammy begins making love to his mother once again. His pace is not as frantic or enthusiastic as when they were doing it doggystyle, or in the shower, but it's far from as languid as their cuddlefuck the other night.

For her part, Beth lies back and enjoys the feeling of her pup giving her what she needs—filling her, loving her. She pets over his back, occasionally running a hand up to scritch behind his ears, as they both watch the rest of the movie together—and together.

He manages to cum inside her twice—once during the movie, and again once the credits begin and he picks up his pace, giving her all he has. The second round tuckers him out, though, and he falls asleep atop her once again.

Basking in the afterglow, Beth turns off the television and allows herself the time to simply be. She finds herself daydreaming about what they'll get up to—what she'll teach him—with the rest of the week together.
