Incest Seduction/Let Stacy continue
"But maybe..." Stacy continues, running her fingers up your leg. "You could put it in her ass."
"Stace... I knew I married you for a reason."
Richard kisses his wife and then leaves the room. While the kids still poke and prod Stacy she chats with you about how one time in college she went on a bender and blah blah. You barely follow the conversation, only just having stopped twitching. Besides, you have other things on your mind. The thought of doing anal is as scary as it is exciting. It’s scary for obvious reasons. It’s exciting just because it’s different. Frankly you'll do anything so long as that demonic toy leaves you alone for a while.
When Richard returns he's carrying a literal chest with him. He plops it down on the floor and opens the lid revealing it to be full of sex toys and accessories. Richard pulls out a wrapper and a small bottle as the kids abandon their mother and swoop in to investigate the weird tickle trunk that just appeared in their living room.
"You didn't need to bring the entire sex chest!"
Richard shrugs. "Y'know, just in case."
The two of them roll you even more to the side until you're fully prone on your stomach. Richard sits down on the center of the towel and Stacy spreads your cheeks squirting a dollop of cool liquid directly onto your starfish. That wakes you up a little more, bringing you to push yourself up to look back at the Taylors. Richard is putting on a condom while Stacy lubes your asshole.
"Kimmy?" She starts sweetly. "All you have to do is relax, okay? Just breathe and relax."
"Ugh-okay." She’s acting like you have a choice.
Richard grabs you a moment later, hauling you up onto your feet in front of him, facing Stacy. The two of them guide you down, forcing you to sit on Richard's lap. Stacy encourages you as her husband's fat cock presses into your backdoor, stretching you wider and wider. You've fingered your bum before, but nothing bigger than that. It feels like his cock may as well be a football the way your asshole stretches and then resists every inch.
"Kimmy! You're doing so good! God, my first time doing anal was rough!" shares Stacy with a chuckle.
You lean forward and grab the edge of the couch, needing to find something stable to ground you. With your feet on the floor and your hands on the couch you finally feel more in control and you sink down another couple of inches then lift yourself that same short distance to groan your combined relief and pleasure as you let out a breath that was trapped inside you.
Stacy rubs your thighs and shares a quick kiss with you. "Mmm, yeah, that's what we want! You fuck that dick."
Richard already pulled you down those extra few inches while you were kissing, so once you pull away you lift yourself up again. After a little more guidance you are quick to find a rhythm and start ass fucking Richard like a real little slut. You're almost twerking on his cock, rolling your hips down to take him deeper inside you. After that realization you've never felt sexier. You'd love to watch yourself doing this, bouncing your ass on a dick. Who knew you'd love anal so much? Probably mom. She was right about your insatiable hole, it just so happens you have more than one.
Stacy moves from rubbing your thighs to rubbing your pelvis. Her knees are planted firmly as she leans into you to get a better look at your still tingly pussy. You're happy to lean back to give her room but can only go back so far before hitting Richard and you lose your grip on the couch. Richard's hands were on your waist but he moves them under you now that you need more support, gripping, spreading, and lifting your ass to keep you going.
"You really do have such a cute little pussy. I never thought I would want to, but..."
Stacy darts forward the rest of the way to land some licks on your vulva. You pause on an upstroke to give Stacy an easier time and she takes full advantage of it. She spreads you open and runs her tongue straight up the middle of your slit. You would have thought your clit would have had enough by now after the vibrator, but it’s more sensitive than ever. As soon as she flicks against it one time you've never wanted anything more.
"Wuurghh."
With that unflattering grunt you throw a hand on her head to keep her close to you. Whether impatient or turned on, Richard decides he isn't going to wait for you to continue bouncing. Leaning back and resting his elbows on the couch, Richard bucks up into you with surprising speed. His thrusts are so hard that his balls manage to slap Stacy's chin as she eats you out.
Do you have some kind of weird sex aura? Does your mere presence cause others to lose control? Sure seems that way. Richard in your ass, Stacy on your pussy. Then there’s Aidan jerking it unskillfully next to a half empty chest and Kalli experimenting on the floor with a vibrator. This is crazy. This is bliss. This is perfect.
"She's ready."
"Hhhuuuuh?"
The high pitch moan you eek out sounds like it came from elsewhere. But it turns into a wild squeal when that roaring dastardly wand finds your clit again.
You buckle forward at first nearly headbutting Stacy. But bending yourself over like this gives you a glimpse of your gash. Your lips are vibrating so fast they're blurry, your pussy literally drooling its arousal onto Richard's ballsack. That's the only glimpse you get as your spine then arches involuntarily, your head whipping back behind you. You throw your arms back as well to catch you, planting your hands on either side of Richard before smacking him in the face with your ponytail. He isn't phased in the least, pounding merrily into your bum. With the pressure from his cock you can faintly feel the vibrator deep inside your ass. Your whole pelvis is tingling.
"FffuuuUUuuhh..." You jerk and moan through the pleasure, already standing on a high precipice. You are gasping for air listing on the edge until you finally fall with a scream.
Richard grabs you firmly, clasping his hand over your mouth to silence you. You fall into him but your back is locked in an arch, your ass clenching the dick buried deep inside it, and your pussy quivering as your clit is tortured in the best way imaginable.
Stacy runs a hand up your body, reaching over your slight, flexed, stretched abs. "C'mon, c'mon, god you're so close! C'mon! Do it Kimmy!"
You haven't closed your legs yet. Maybe cuz they're shaking too much. You slap your hands onto your chest, squeezing your tiny tits violently, your nails pinching your flesh. Touching your body makes you realize how hot and sweaty you are. Stuck in a hurricane of pleasure, you're desperate to give Stacy what she wants, you just don't know how.
An eternity later the vibrations stop. You draw in the first deep breath you've had in minutes as everything between your legs comes to rest. Now you're afraid to close your thighs, not even wanting your lips to touch each other.
"Oh dammit. We were right there too. I could feel it. Oh you poor girl." Stacy stands and pats your knee. "I'll get you a drink."
Stacy walks away but there's still in dick inside you. Uncle Dick. You're reminded of this when he starts moving again. Agonizing, taunting, short little thrusts as he clenches his cheeks to push deeper between yours. He's slow and deliberate, taking his time, waiting for every squeeze, every small reaction he can coax out of you. A weak groan gets muffled by Richard's hand which is still locked over your mouth.
"How is your ass even better than your tight little pussy?"
His whispered words are followed by fingers that pry at your folds. You assume they're Richard's at first but they seem very small. Your skin is still coursing with electricity, your pussy doubly so, and every little poke and prod makes you twist and moan.
"Fuck. I bet your sister's an even bigger slu-"
"Aidan!"
Stacy's shout startles you and Richard both. You look down your body to see their oldest between your legs with his hand hovering over your crotch, caught in the cookie jar.
"But you said we're touching now," he complains.
"Yes. We are..." An uncomfortable silence follows, Stacy not sure what to say next. She may not know why she even stopped him. Obviously it's a weird thing to walk in on, your young son feeling the pussy of a girl getting butt fucked. No doubt the shock of that threw her, but when she takes a sip from one of the cups she's holding and keeps walking Aidan smirks and touches you again. It's only when he notices you watching him now that he jumps and scurries away to feign innocence next to his sister. Kalli doesn’t mind as she is more than happy to show her brother the vibrator she has quickly grown fond of.
Stacy places her cup on a nearby side table then brings another to you. You're finally stood up on uneasy legs, gasping when you suddenly find more space inside your body, an unexpected euphoria coming from thick Richard pulling out of your ass. You are sat right back down onto the towel afterward, if only because you can hardly support yourself. You take an eager swig from the cup Stacy offers you expecting a refreshing drink of water but are surprised to find more margarita. You shouldn't be surprised really, she sure enjoys a stiff drink. Disappointing at first but still welcome after a little thought, you throw back the cup of confidence with a small wince followed by a sigh of relief. At least you wet your lips a little.
"You're a thirsty girl!" notes Stacy taking your empty cup. She crouches down in front of you, looking straight into your eyes. "How are you doing?"
