Hot Summer Job/Admit you were just thinking about Larissa.
Based on the topic of conversation thus far you do want to tell her, but you can't get it out right away. It still feels risky, admitting something like that. "Oh, uh... nothing."
"Well that's bullshit," notes Carrie, stopping her handjob to call you out. "I saw the look on your face just now. That was definitely something. Now..." Carrie looks down as she moves her hand up and down your dick again, but she does so slowly, seductively. You both watch for a moment, her hand tugging your thin foreskin back with a satisfying little stretch at the bottom, then pushing it back up over your thick glans, the edge of her slender finger skirting across your ridge as she goes. She looks up with sultry eyes, her voice soft but playful. "Be honest... whatcha thinkin about?"
"L-Larissa..."
Carrie doesn't even blink as she stares at you. Her expression doesn't change, not at first. Her hand just keeps a slow steady pace. You swallow the lump in your throat, completely ready for her to freak or throw you out. But she doesn't. Instead a dirty smile creeps up the corners of her mouth. She leans forward and kisses you again before rising from Kylie's bed and guiding you up as well. Holding your hand, Carrie leads you out of her eldest daughter's room just a few steps down the hall and into her youngest's.
Carrie tugs you inside and pulls the sheets back before pushing you down onto Larissa's bed. Given the evening thus far you expect her to start roleplaying as Rissa at any moment but curiously she stays silent. Once you're laid down she bends over you and kisses you again, slipping you some tongue while you play with her tits. When she stands back up you can see that she slipped off the small panties she was wearing, now in her hands. After flipping them inside out she bends down again, guides your bottom lip open with her thumb, then pushes the wet gusset of Rissa's very messy panties into your mouth.
"You want her on your tongue, don't you?" she whispers, one finger stuffing more and more of the pink cotton underwear into your mouth. You barely nod, the tension sky high as she packs her girl's panties past your lips inch by inch, eager to watch them disappear.
Once you're able to close your lips, Carrie smiles deviously, another idea crossing her mind. She darts to the corner to raid Larissa's hamper for what must be the second time tonight. She pulls out two pairs of panties and tosses them down after inspecting them, then retrieves a light purple pair that seem to satisfy her.
"Third time's always the charm, isn't it?"
Carrie hooks the front edge of the purple waistband below your chin then pushes the opposite side up over the top of your head. It doesn't really want to stay there, but then she stretches the sides out one by one, hooking behind your ears using the two leg holes to help keep it in place. You can barely see out past the inside edge of the pantie's crotch once she's done, but the gusset is stretched right along your nose. If you weren't sure about Larissa's taste before, you're pretty sure what she smells like now, the lightly crusted cloth on the inside of her underwear delivering the scent of raw fourth grade pussy straight to your nostrils.
Wearing nothing but her pigtails, a huge smile, and Kylie's tight tank top, Carrie mounts you on Rissa's bed. She rubs her slit against the underside of your flipped up cock then shoots forward to kiss your cheeks, pull on your hair, and lick your ears. The horny mom rolls her face across yours, nibbling at your lips through Larissa's underwear and taking sharp inward breaths. It takes a moment before it occurs to you that she's sniffing her own daughter's panties as they lay stretched across your face.
This lady is crayzee.
Carrie sits up after a couple minutes of humping and teasing and takes you into her pussy for the first time. She's got some sort of kegel thing going on. She grips you crazy hard once she's halfway down your rock hard dick. While squeezing, she pushes her pussy down on you, forcing your cock past her tight inner walls and stretching her lips as if you were the one forcing yourself onto her. Once she's got you good and buried she lets out a sigh and stretches her hands forward onto your chest while you rub yours along her sides.
"Mmmm... you're so baaad..." she moans, grinding her pelvis against you. "And so haaard... Your own sister wasn't enough, was she? You just had to have my daughter too..." Carrie bucks faster, her rolling hips speedily fucking you with only an inch of travel as if she refuses to take anything less than all of your cock at any moment.
"How did you talk me into this?" Carrie's tone changes suddenly, accusatory, catching you off guard. "What?! You're going to fuck her too? After you're done with me?! Shh, shhh..." Carrie reaches up and places her fingers on your lips over the cotton covering them. "It's okay Rissa baby. Don't you worry about that. You just let him lick you where he wants. Just like you did for mommy before, kay...? I know it tingles. It's okay... good girl."
Given the panties crammed into your mouth you assume Carrie is perfectly content with riding the mute cock beneath her. She likely set it up that way on purpose so she could weave her own story for herself. You're not complaining. The competing flavors that coat the forbidden fabric in your mouth sure do amplify your own arousal. You suck on the soiled underwear packed into your cheeks, trying to tease out mother from daughter, comparing its subtle musk with the stronger one hugging your nose.
"I can't believe I ate out my perfect little girl, my own daughter... her soft, sweet, tiny pussy..." Carrie leans down, nipping at your face over Larissa's panties once again. Her hips roll back, pulling herself two thirds of the way up your shaft before she slams back down, finding a new angle and rhythm that makes her head bob in front of yours.
She whispers to you as she pants rapid breaths, taunting and teasing you with her skilled pussy that is all but sucking your eager cock. "I can st-still smell her. She tastes good, doe-uhh-sn't she? Hmm? Mmm, I know she does. Her cute, mushy pussy lips. Her little thighs twitching around your head as she... moans. So delicate... pure... eh-even when she's... getting wet..."
Carrie blowing into your ear, her juicy pussy slamming your shaft, the taste and smell of her daughter overwhelming your senses... you release a muffled groan through Larissa's panties just before you release your seed inside of her mom.
"Yes... yes... yes! Give it to me, you stud!"
The crazed milf hops off of you mid-orgasm, grabbing and squeezing your slick cock to give herself enough time to quickly slide her legs off the bed and onto the floor. But even with her tight grip, your balls strain and fire a wild scattered blast of thin semen past her fingers and into the air, raining down along your side and spackling her daughter's bed sheets.
You assume as she brings her mouth down onto you that she's going to try to throat you again, to swallow what she's saving of your orgasm. But she merely sticks out her talented tongue and runs the tip over the slit in your glans and down around your ridge as her hand begins to pump you. She doesn't even try to direct the carnage; she lets your spunk fly where it may, spraying across her face, deflecting off of her tongue, splashing Larissa's bed, and showering your own pelvis with small droplets of cum.
Puffing and grunting to give her everything you've got, Carrie keeps pumping and you keep flexing. The unmotherly smile on her face as she works your straining cum fountain and drools onto your shaft gives you all the motivation you need to propel every bit of bodily fluid that your balls can muster up into the air. She just giggles to herself when your cock continues to flex under her ministrations but you have nothing left to give her.
"Have I told you how much I love high school boys?"
You give a halting nod as Carrie slips her lips over your glans and down the full length of your waning cock. She literally swallows you, guiding your tip into her throat, then bobs your head on your meat while she slurps and sucks. Your spent cock flexes uselessly and your abs along with them, your body buckling forward as your penis is given no reprieve. One final grunt and you throw your head back on Larissa's pillow as Carrie pulls off you. Deep gasping inhales through your nostrils suck in all of Larissa's scent. The smell of her panties are so familiar to you now, this orgasm ingrained in your mind, you'd swear you could smell the girl across a crowded room.
