The tension filling the car is thick enough to choke on. Bridget keeps her hands firmly on the wheel, but does risk the occasional glance at Ava in the passenger seat whenever it is safe to do so. The girl is sitting silently, curled against the door to make herself as small as possible, staring out the window. It’s been nearly two weeks since their previous... encounter, but that’s not what has them both on edge.
“Are you going to say anything?” Bridget says sternly. She’s angry, but trying to keep it in check. She’s used to Amelia being the child who acts out; Ava is supposed to be better than this.
“Do I have to?” Ava asks in a small voice.
Bridget clenches her teeth and counts to ten in her head. She knows, theoretically, that it won’t do much good to approach her step-daughter in anger. She tries to reach for calm and understanding. She can’t help but feel like this is her own fault anyway, somehow. She should never have let Amelia bring Ava into this situation at all. Who knows what weird thoughts it put into her head. At least Bridget was the one at home when the principal’s office called, and not Jade.
“I’m trying to understand,” Bridget says firmly. “You’ve never been suspended before. You’ve never even come close! You’ve always been a model student. And then I find out that not only are you having sex with another student, you did so in public? What on earth has gotten into you?”
“She’s my girlfriend!” Ava protests.
“That doesn’t make it okay, and you know that,” Bridget points out. “What the hell am I supposed to tell your mother?”
“You don’t...” Ava hesitates. “We weren’t trying to do it in public. I mean, we weren’t trying to get caught. It was under the stairwell between classes; no one would have seen us if that hall monitor hadn’t happened to come by.” She bites her lip, sounding like she’s on the verge of tears. “You don’t have to tell mom,” she whispers softly.
Bridget sighs. “I’ll consider it,” she concedes, in part because she genuinely doesn’t know how to begin to explain this to Jade herself. “But you’re going to have to give me more than that. You’re smarter than this. Tell me why you did it. Help me see it from your point of view.”
“Well, it’s ‘cause... you...” Ava keeps stumbling over her words, like they’re being drawn out of her against her will. Her voice has gotten so small that Bridget almost has a hard time hearing it over the sounds of traffic around them. Finally, the girl takes a deep breath and says in a rush, “it’s ‘cause you wouldn’t help me out again!”
Paused at a stoplight, Bridget turns her head to look at Ava completely, startled. The girl is still making herself as small as she can, but her hands are tightly fisted together in her lap, her arms a solid line of tension.
“What do you mean?” Bridget asks. The light turns green and she has to turn her attention back to the road again.
“Well, after... you know...” Ava hesitates once more, clearly getting up her courage. “You said- I mean, I guess Amelia said, but... you said you would help me with... with any questions I had, and... and I’m just... I’m getting so horny these days, and I don’t know what to do, and Kaylin said it would be okay, and I just...” She shrugs minutely. “I wasn’t thinking.”
Bridget curses inwardly. Unfortunately, she does remember what it was like to be fifteen. If she’s being honest with herself, her libido was only slightly worse then, at its initial onset, than it is now. Although at least now she’s had several years to practice dealing with it. When it’s the first time...
She sighs. “I don’t want your Mom to find out about this. About... what happened. Between us. It’s bad enough dealing with Amelia, I figured it would be safer to leave you alone.”
“You didn’t...” Ava’s voice trembles with unshed tears. “You didn’t like it?”
Bridget huffs. “That’s not the problem.”
“I won’t tell Mom!” Ava insists. From the corner of her eye, Bridget sees her blush and look down. “If you wanted to do it again...”
Another red light. Bridget looks over once again at her middle stepdaughter. When she’d gotten the call from Ava’s school she’d been in the middle of jerking off, and her cock happily reminds her that it was expecting satisfaction. Ava is still wearing her adorable school uniform with its short little skirt and button-down shirt.
Taking a hand off the wheel, Bridget reaches over to the passenger seat and slides her hand up beneath Ava’s skirt and over to her crotch. She hears Ava gasp as Bridget’s hand touches her through her panties. Her underwear is soaking wet, and she can feel the bulge of the girl’s cock straining to come forward; she’s still half hard.
Bridget idly kneads both sets of genitals lightly through the fabric, making Ava mewl with desire. “If I help you out,” Bridget proposes, “you have to promise you won’t try to have sex at school again, okay? There’s a time and a place for everything. And you can’t tell your mother either, obviously.”
“Mnnn,” Ava moans, “I promise. I swear I won’t!”
“Good,” says Bridget. She proceeds to drive the next block one-handed as she continues to palpate Ava’s crotch beneath her skirt. She doesn’t remove any clothing yet, knowing they’ll both still have to get out of the car once they get home, but she can feel Ava’s slick dripping down her thighs, slippery and eager.
When she finally parks the car in the driveway, Bridget takes a few deep breaths for the purposes of self control and then steps out. Ava has already bounded up to the front door and is standing there waiting for her with a sort of shy eagerness. As soon as Bridget unlocks the door, Ava darts inside and slips off her shoes as quick as she can before padding down to her parents’ bedroom.
Bridget follows at a more sedate pace. When she arrives, Ava has already dropped her panties onto the floor and is sitting in the middle of the bed, staring up innocently at Bridget with those wide eyes of hers. Bridget swallows, knowing she’s already helpless but wanting to at least project the semblance of some kind of control.
“Alright,” she says, sitting down next to Ava on the bed. “If you’re going to get used to controlling your libido better, you need to learn to get the most satisfaction for yourself when you do have the time and privacy to get off.” She helps Ava lie back, propped up against the pillows, and then reaches once again under her skirt to her now-bare privates. This time she inserts two long fingers into Ava’s young hole, slick with anticipation. Ava gasps as she’s entered without warning.
“From my experience,” Bridget says, “the orgasms from your penis will be much more intense and satisfying if you can get yourself off a few times with your pussy first.” She slides the fingers back out, satisfied with how wet and relaxed Ava is.
“Another important thing to note,” she tells the girl, tracing the shuddering edge of her hole with one damp fingertip, “is that this particular hole is very resilient and flexible. It can take a real beating, so you don’t have to bother being too gentle with it.” So saying, she proceeds to ram her entire hand and wrist into Ava’s vagina.
Ava screams. It’s a good thing that it’s the middle of the day and no one else is home; she’s definitely audible throughout the entire house. Bridget smirks and forces her arm further into the girl, almost halfway up the forearm. Then she pulls out a little bit and proceeds to thrust, pistoning her arm back and forth and slamming her hand into the depths of Ava’s girl parts over and over.
Ava writhes on the impaling hand, shuddering and moaning. With her free hand, Bridget reaches up to the girl’s top and slowly undoes the buttons one-by-one. It’s difficult to do one-handed, but eventually her shirt falls open, revealing the pale, lacy lavender bra that barely manages to contain the girl’s enormous breasts. Bridget grabs one in one hand and squeezes, kneading it in time with the continuing thrusts of her hand into Ava’s orifice.
She keeps going as Ava’s keens rise in volume, her hips lifting from the bed as she’s pleasured. It takes a while—Ava is clearly unused to getting off without using her penis—but eventually she feels the girl’s pelvis snap upwards and convulse around her wrist as Ava’s orgasm sweeps across her body.
Ava lies gasping, her massive bosom heaving up and down, as she comes down from the pleasure of her climax. Her cock is stiff as a flagpole, tenting up her skirt, but Bridget continues to ignore it. Instead she slides down to be eye level with Ava’s nethers, grabbing one of her legs in each hand and spreading them to get a better look at her delightful, eager hole.
“In addition to orgasming separately with your vagina and penis,” Bridget tells her, “many people with our parts can also experience multiple orgasms in a row. Especially from the vagina. The more you can get off there first, the more it will stimulate your cock, and the better your climax will be there when you finally reach it. Let’s see how quickly you can get off again.”
She leans down, forcing Ava’s legs apart, and brings her face to meet the young girl’s pussy. She inhales once, deeply, before sliding her tongue into the girl’s hole and going to town.
Ava lets out one more high-pitched squeal as her stepmother’s tongue comes into contact with her lady parts. Then she proceeds to settle down into a lower, rhythmic moaning and whimpering as Bridget alternates between lapping a slick trail across her hole and the very bottom of her cock and thrusting her tongue into the girl’s orifice.
As she continues to eat the girl out, Bridget lowers the hand she had been using to penetrate Ava earlier and brings it in close. With far more gentleness than she had used when attacking the girl’s primary hole, she proceeds to slowly, gradually slide a single slick finger up the girl’s ass. This causes an extra-sharp moan from Ava. Bridget pushes the finger deeper, deeper, until it’s as far in as it can go, buried up to the knuckle.
She keeps the finger up Ava’s ass the entire time she goes down on her, occasionally giving it a couple deep, earnest thrusts, but mostly simply leaving it embedded in the girl’s rear hole. When the skilled attentions of Bridget’s tongue finally bring Ava once again to orgasm, she can feel the girl’s rectum also clench and spasm around the finger, helpless under the waves of pleasure rocking through her.
Bridget backs off once more, wiping off her mouth and watching as Ava lies panting from her second climax. The girl looks absolutely wrecked, but her cock is still a desperate spike, so hard it’s weeping fluid from the tip.
Bridget backs away for a moment, just long enough to get to the edge of the bed and remove her own pants and underwear. She herself is pretty turned on as well at this point, her cock eager and ready to go. She returns to the middle of the bed, once more grabbing up one of Ava’s legs in each hand and spreading them apart around her hips.
“If you can,” she says, still dutifully fulfilling the role of teacher, “it’s almost always more satisfying to come with your cock inside of something or someone than it is to just have it exposed to the open air. There’s nothing quite like being inside a soft, welcoming pussy.”
So saying, she guides her own massive erection to Ava’s entrance and begins to push into her step-daughter. Ava’s eyes widen, then abruptly squeeze closed in bliss as Bridget’s gargantuan cock claims her, sliding home into her well-prepared and sopping wet hole. “Yessssss,” she hisses as she is penetrated.
“That said,” Bridget says as she begins to thrust into Ava, mercilessly hard and deep, forcing another inch of her cock into the girl’s well-used orifice with each movement, “you often won’t have an opportunity to do so. No matter how excited and willing your girlfriend is, there are many times and places where it’s just not appropriate to have sex with a partner.” She slams home particularly hard on that thrust, to emphasize the point. “In that case, you need to be able to get yourself to a restroom and just get off quickly, so you should practice being able to quickly and quietly jerk off with only your hand, to get yourself used to it.”
Ava blinks up at her and reaches downward, her hand heading for her own cock in order to follow her stepmother’s instructions. But Bridget bats it away and simply shakes her head. “Not right now,” she says. “I want to get your pussy one more orgasm before you get off there.”
Now that she’s completely bottomed out in Ava’s body, balls-deep, Bridget grabs the girl’s thighs in her hands and proceeds to slam into her with a savage ferocity, wrenching the girl’s hips down onto the spear of her cock at the height of every thrust. She fucks her punishingly hard, trying to impart the importance of obedience onto her with the sheer force of her thrusts alone. Ava moans helplessly at every single one, crying out in overwhelmed pleasure as her overstimulated pussy is driven into again and again.
Despite the harshness of her thrusts, Bridget takes it slow, taking her time plundering Ava’s body to her heart’s content. She’s not sure how often she’ll get a chance to enjoy this sweet, young hole, so she feels like she should make the most of it while she can. She sighs with contentment as she takes Ava over and over, impaling the girl on the thick, meaty spike of her dick.
“If you really have trouble controlling yourself,” Bridget says conversationally as she continues to fuck her daughter, “we can always get you a toy to help you out. We can buy you a big ol’ strap-in to fill you up while you’re at school, to help keep your pussy nice and stimulated.” She grins wickedly down at Ava, who doesn’t see it with her scrunched-closed eyes. “That should help make it easier for you to get off with your cock, if we keep your hole nice and well-fed like that.” She gives a particularly harsh thrust. “Or maybe a two-prong, hmm? Would you like having one big fat rod up your pussy and another up your ass at the same time, just like your sister does?” She laughs as Ava whimpers audibly at the thought. “Just let me know, and I’d be happy to buy either one for you, if it keeps you out of trouble.”
“I-” Ava tries to speak, but is clearly having trouble. Her face is flushed, though whether just from how turned on she is or from the mental images Bridget has planted in her mind is difficult to tell.
Whichever combination of the two, it is clearly too much for her; a moment later, Bridget feels Ava spasm and clench around her cock as a third orgasm rocks her body. She writhes on Bridget’s impaling spike as pleasure surges through her for nearly an entire minute before finally subsiding. Bridget keeps her cock balls-deep inside the girl through the entire climax. Only when she finally subsides does Bridget perform her own final handful of thrusts before letting go and blowing her own load inside the girl, filling her passage with sperm. Her balls clench as they empty themselves into Ava’s body.
Afterwards they both lie still for a moment, breathing. When Ava’s eyes finally open again, Bridget sits up and gestures down to the girl’s still desperately hard cock. “Now,” she says, “show me how you get yourself off.”
Gulping, Ava pulls her skirt aside and reaches for her own cock, hefting it lightly and beginning to tug at it.
After a minute or two of watching, Bridget puts her hand over Ava’s and guides her motions, showing her how to do it firm and slow, maximizing the pressure and the pleasure. She pulls her stepdaughter back into her lap for easier access, the girl’s back to her front. As she continues to help the girl please herself with one hand, she reaches up with the other to fondle the girl’s breast. Poor Ava’s boobs are so massive that even one is more than a handful, even for Bridget’s own large hands. She kneads it hard, possessively, as they continue to jerk Ava off.
It doesn’t take long. Ava cries out helplessly as her phallic orgasm hits her, a massive load of cum positively bursting from her repressed organ, firing so hard she hits herself in the face, getting cum on her nose and chin and in her open mouth. She hardly seems to notice, mouth and eyes both open wide as she barely manages to hold together on under the sheer force and intensity of her orgasm, coming and coming and coming endlessly.
As she finally comes down, panting and gasping, chest heaving with her breaths, Bridget smiles to herself and gives her chest a final squeeze before letting go. Ava collapses sideways onto the pillows, apparently unable to even hold herself up. She’s a mess: her clothes are all over the place, bra half off and exposing both her nipples, her chest, neck, and the bottom of her face are covered in her own cum, and the inside of her legs all the way down to her ankles are a crude slurry of her own slick and Bridget’s semen.
“Well?” says Bridget finally, after they’ve rested several minutes in silence. “How was that? Educational enough?”
Ava sits up and tucks her wildly disheveled hair behind one ear, not meeting Bridget’s eyes. It’s a little hard to tell with her face angled down, but she seems to be wearing a small smile. She nods self-consciously.
“Good,” said Bridget. “Now remember what you promised. No telling your mother, and no more sex at school, okay? If you need to bang your girlfriend, go to her place or bring her back here where you two will have privacy, got it?”
Ava nods again. As Bridget starts to get up, however, Ava grabs her hand. “Um!” she says, halting her stepmother in place.
Bridget pauses, sitting back down. She waits, silent, until Ava looks up at her once more from beneath her long eyelashes. “Umm,” she starts again, “would you... could we do this again...?”
Bridget sighs and thinks about it. “Well, you’re still suspended tomorrow. To be honest, I’d rather not have to explain the incident at your school to Jade either. Tell you what. I’ll drive all you girls in to school tomorrow so that she doesn’t notice that you’re not going, and then I’ll bring you back here and fuck you all day, how’s that? But after that we really have to keep it on the down-low, okay? We can’t do this too often if we don’t want her to find out.”
Ava nods her agreement, but doesn’t release Bridget’s hand. After another moment of silence while she apparently works up her courage, she eventually says, “And then... and then you can maybe, uh... get me that toy you mentioned?”
Bridget’s smirk returns. Jade’s daughters really do take after her. “Which one?” she asks.
“Um!” Ava squeaks. “Just- just the single one! Just the one for the front. F-for now.” Her face is crimson with her blush, and she’s once again not meeting Bridget’s eyes.
Bridget laughs. “Alright then, as you wish. We’ll find something to tuck up inside you nice and snug while you’re at school, to help keep those horny feelings down, hm?”
Ava swallows. In spite of how hard and how many times she just came, her cock twitches in interest at the idea beneath her skirt. Geeze. She really wasn’t kidding about the intensity of her libido. Bridget is frankly impressed.
She leans forward to give Ava a swift, soft kiss on her forehead. “Don’t worry, sweetie,” she says. “We’ll make sure you’re taken care of.”
