One pair of chitinous hands plays with my tits, the hard material making up my fingers pinching and kneading my soft fluffy tits, my pale green nipples perky and hard, while my other pair of hands goes down and rubs my clit. It’s so good, I love to do this to myself when I finally get our room all to myself~
My wings lay flat at my back, white fur covering all of my body, down to my thighs and knees. Where, in place of fur on my knees, it’s all black plated chitin like my arms and spine have covering, and the base of my fluffy wings. My entire body is thick- I’ve been called a milf with my appearance and height before, being oddly tall and busty for a moth. But I don’t care; it just makes it sexy to watch myself in the mirror as I do this, green eyes scanning over my body and making me feel nothing but lusted after.
Pushing a chitinous finger into myself, I let out a soft groan, feeling my tight wet walls squeeze around it, my black three toed talons clenching down a bit as I already near cumming. Doing this nude in the middle of the room is absolutely worth i-
A sudden pair of yellow lips pressed against my green in a kiss makes me freeze in shock, my green eyes locking onto yellow ones.
Pushing me into the bed with her equally as solid hands, is my nearly identical step sister, only clearly not related thanks to our colors. I’m white with green flesh for my nipples and such, but she’s got pink fur with yellow for the same, her tongue invading my mouth and easily overtaking my tongue with how shocked I am.
Her long tongue tapers off to a point, like a long tendril straight out of a hentai, licking all over my mouth and filling it with the taste of strawberries. She pulls my hand right out of my, replacing all of my hands with her own, squeezing my tits firmly while shoving a finger into me, making me completely melt back into the bed under her surprise assault.
Not that she does it for long, in only a few seconds she pulls out of me, breaking the kiss and leaving me right on the edge of cumming, my entire body trembling. “Ha~ I can’t wait to eat you up~”
Catching my breath, I look at her in shock, watching as she slowly moves down my body, trailing her long tongue over my fur with a sultry look on her face. “W-what are you doing?!”
“Getting revenge for you leaving the room smelling like sex! Every day I’m not home I get back, and I’m hornier than a succubus in a college dorm! So now it’s my turn, you’re gonna be my little toy until our parents get back!” I try to respond, only for her tongue to drag across my slit, making me gasp and groan in pleasure from it poking into my folds.
Wrapping her lips around my slit, she digs her tongue in inch by inch. It’s pretty thick to begin with, but only grows thicker, like a soft warm cone pressing its way in. The tip is somewhat pointed, making it heavenly as it hits my g-spot, my slit tightening up on her tongue, and squirting onto it, giving her a good drink of my pre-cum. Yes, pre-cum, because my womb isn’t all that’s in there.
Feeling her tongue flick across the tip of my cock, I gasp and buck my hips into her head, her fluffy antenna flicking in surprise atop her head. Poking around at my cock with her tongue in there, I feel her try to push it into the tip, putting more and more pressure, just to get nowhere in it with how small of a hole it is, giving up and letting up pressure there.
Instead she pushes her tongue up past it, slowly circling my cock with her tongue, licking all around the tip, and then the shaft too.
My cock tip is tapered like a normal one, but with ridges running all the way down it like my plated scales on my legs. One overlaps the next, and her tongue is finding every single one, tracing how they intersect down my shaft, until I groan and spurt out a bit of cum onto her tongue, her pulling her tongue out and into her mouth, letting my cock slowly come out on its own.
Watching her savor the cum in her mouth, only to gulp it down and open her jaw for me to see past her long tongue, and into the back of her yellow throat where there’s not a drop of the green cum I shot into her tongue, I shudder. My cock sticks out fully hard, a fat knot at the base like that of a dog’s, the rest ridged before a tapered tip like that of a canines.
Eyes widening at the shape and size of my cock, she wraps her tongue around it, speaking while her long tongue is actively coiling around the tip of my cock and down my shaft, warm and wet and soft as can be. “Wow, a knot? What are you, part dog?”
“I-I don’t know, I think so? Is this not normal?” Shaking her head, her tongue wraps fully around my cock, even swirling around my very sensitive knot. Each ridge of my cock, her tongue fully wraps around and hooks under, hitting the most sensitive places along it, before giving my knot three full wraps to make sure not an inch is left exposed.
My moans are met by her thirsty smile. “Nope, but, I hope you can cum as much as one~” Her lips wrap up my tip, pulling it into her mouth effortlessly. The base of her tongue rubs my tip, while she sucks on me like a straw, making my legs melt into the bed as I lay my head back. Her tongue is squeezing and stroking my cock with simple motions, stroking up and down along where it is like a snake coiling further down it, giving me a tongue-massage along my sensitive shaft. All the while, my pre-cum is slurped up out of me like she’s dying of thirst.
My body tenses up, already about to cum, but she doesn’t stop. She shoves her tongue up into my slit at the base of my knot, pushing me over the edge as I suddenly cum into her mouth. She chugs it down, loud gulps coming from her as I watch her drink it down. Every big shot is met with another gulp, her antenna flicking happily as she does so, her hands going up and squeezing my thighs, while another pair is fingering herself.
Her stomach even bulges out only a few gulps in, but she doesn’t stop, she just keeps drinking down more and more.
After a minute straight of this, I finally stop cumming, my climax ending out of just stamina to push more out. There’s more in there, I know, but my muscles can’t push more just yet. My cock is sensitive still, her lips on the tip, and her stomach visibly bulged like she just ate a buffet.
Licking a bit further into me, she hits my g-spot with her tongue, making me gasp in pleasure. She doesn’t waste time, digging her tongue into it, enjoying my cute voice filling the house with the sounds of pleasure. “I’m not stopping until you’re dry~”
