You go onto bed.

I decided against interrupting her. I was really tired and she would probably be too.

Turning over I let myself drift to sleep.

I wake slowly to the strangest sensation. My lower cheeks and legs were cold in the air conditioning, but a pair of small warm hands gripped them and a wet tongue licked my ass slowly. The tongue licked slowly up from my taint up to my anus, or boi-pussy as was the colloquial term now, and up to my lower back. I gasp as i feel a finger probe a single knuckle deep before swirling around the ring of muscle. Alyssa giggles and I gasp again as she smacks my ass hard with her other hand. I groan, grabbing my phone in the darkness before turning it on, squinting at the bright light and the number 2am written on the screen.

“Come on Alyssa, it is literally morning right now.”

“Its fine, just keep sleeping!” She says.

I turn back and shine the light on her face. She had spread my legs and was kneeling over my ass, half naked and sporting an erecting, her dick bobbing cutely with need. She glances up guiltily at me. Finger still buried inside me.

“Fine” I sigh, “Just be quick about it, I have school tomorrow then we need to get ready for mom to come home”.

She nods and I switch off the phone, “Back up for a sec” I say, before grabbing my pillow and putting it beneath my hips to prop up my ass, then resume my face down position. I wriggle and get comfortable before moaning as i feel her spread my cheeks wide mash her face between my asscheeks and tongue my ass. After a few more seconds she withdraws, leaving my ass warm and slimy from her saliva and my juices. There is a second of pause before I feel her elbows on either side of my chest as she positions herself behind me, mounting me from behind. Her thighs rest on my thighs, and in the complete darkness I feel her warm cock rubbing up and down my ass crack, before the warm spongy head stops. For a moment, her urethra kisses my entrance, before she slowly starts to lower herself into me. I feel the ring of my ass widening to accommodate her mushroom shaped head, and we both moan when it pops closed around. Her other elbow came down next to me. Inch by inch her dick widens the walls of my ass.

Finally i feel her hips pressing against my cheeks, her balls coming to rest lightly against mine.

Balls deep, her cock feels warm and snug inside me, I feel her sigh and she lets her entire body go limp, breasts pressed against my back, arms akimbo and legs to either side of my hips. Her dick throbs deep inside of me and the lust starts to rise in me. Despite my earlier **** we both knew how much we loved this.

“You feel so warm inside” she murmurs in my ear, making me shiver.

I dont respond but push up lightly with my pelvis with insistence, causing a schilck sound and driving her a little deeper inside.

She gets the hint and start to draw her hips back, the friction starting to scrape the inside of his tunnel. She stops with just her cockhead inside him, then lowers herself back.

She keeps this slow, loving humping and I sigh in contentment. After a few minutes she picks up the pace, and with an unspoken agreement I get up and assume the fabled face down ass up position, still connected to her.

She grips my hips and starts to pound herself into me, her strokes becoming deeper and smoother. She is not new to this, and her years of practice show. The room becomes warm and humid, filled with the sounds of slapping flesh and the wet schlick schlick of her cock pistoning in and out of me. I grip the sheet as the friction of her heats my ass almost unbearably. As I look back, on my elbows, I see my bobbing cock and feel her own sack lightly slapping mine.

I start to push back against her, meeting her stroke for stroke and driving her even deeper. I cry out in surprise and pain as she grabs my hair and wrenches my head back.

That is new, i thought. But so fucking hot I nearly came right then and there.

Every stroke of her cock sends a wave a pleasure through my cock and balls, and a shiver of delicious pain up my back. She isnt naturally big enough yet or well practiced to stimulate my prostate, but the constant pressure is enough to make me go crazy.

“Hooo fuuuck…” I mewl as she grips my hair tighter and pushes me down back onto my face. She pulls out suddenly and I feel the emptiness, the cool air brushing against my exposed inside.

“Turn over, i want to look at your face when I cum…” She pants tiredly.

I flip myself over quickly and spread my legs for her, and she quickly sidles up on her knees before angling her hips downwards. She locks eyes before hilting herself deep in one stroke, drawing a gasp from me. I lightly wrap my legs around waist, and start to work her shaft by clenching my inner muscles and assholes each time she pulls out, effectively milking her cock for her sweet girl cum. She really impressed me by grabbing my head like that, taking control of her boy like any good futa would. She grins at me as she feels the change before rewarding me with an extra hard few strokes, pounding hard enough that my cock and balls bounce back and forth.

The waves of pleasure from her strokes start to cumulate in a throbbing ache in my ass and balls and cock, my whole pelvic area, and I stop my conscious stimulations of her cock, losing control. Alyssa recognizes the change and leans forward, face wrapt with pleasure, somehow accelerates even more her pace, cute little tits heaving with gasping breaths.

“Cumming…” I whisper out, before the convulsions hit. My dick starts spurting out white ropes of runny cum onto my chest, some going so far as to hit my face, but I dont care. My ass clenches and unclenches from the massive orgasm and that sends Alyssa over the edge. I wrap my legs tightly around her not wanting to lose a drop over her semen, watching as her body tenses and buries her cock one last time into me.

“Fuuuuuck yessssssss” she moans out, her hand gripping my cock hard unconsciously. The pain is not enough to detract from the beauty, and the feeling of warmth blossoming inside me, her girl cock unloading pulses of thicc white semen deep inside me. She holds still and continues cumming for a few more seconds before she collapses in my arms. I hold her in my arms, letting my legs relax to either side of her. Gently stroking her hair as she heaves for breath. Her dick is still inside me, but I feel it slowly softening while inside me, the sensation of her softness inside of my wet, sloppy ass making me giggle. Alyssa rouses herself with a start, having fallen almost asleep.

“That was amazing ! Even better than usual !’ She exclaims, looking up from my chest.

“Yup, that was pretty fucking awesome. You are getting really good at this. Did you see how it felt when you grabbed my hair ?”

“Yas you really sucked my dick in when I did that. It was weird, i got this weird feeling and it felt right to, like, take control ? Of you ? Besides, you made my dick nearly melt off after that”. She questioned.

“Yeah that is what you are supposed to do. Any good futa will know what to do and how to take control of their partner. I think you are developing finally. You will probably start doing that more often. And to be honest, you saw how I reacted.” I say.”Let me tell you a secret. I almost came right then and there.”

She grins at that and lets her head fall back to my chest.

We spend a few minutes like that, just breathing together. Her dick is nearly flaccid now, with a twist of my hips i pull myself off of her, there is a small gush of liquid that runs down my asscheeks onto the bed. She starts and pulls back from my arms, and I let her go.

“Sorry I’ll clean up” She mumbles sleepily.

“No dont worry, let me clean you off instead”. I grab her dick, soft and flaccid, but wet with her cum, and lean down to take her in my mouth. She sighs with contentment as I swirl her around my mouth with my tongue, carefully cleaning and swallowing the remaining cum and musk. I very carefully suck on her urethra to get the last bit of cum out. Then release her with a pop from my mouth. I take a second to kiss her stomach before releasing her.

“Thanks bro, I love you,” she mutters before stumbling over to her bed and collapsing. I take a moment to admire her pale cheeks and pink lips leading up to her balls. So cute, I think.

I lay back down and dip a finger inside my ass, feeling the slimy wetness of her cum. I get up tiredly, my legs and hips feeling slightly sore from the exercise, heading to my chest of drawers. Fishing around inside the top one, I find among all the toys there a small buttplug with a wide base, a deep red color. I was too tired to take a shower and clean right now so a plug would be best not to stain the rest of my sheet. Besides, I like the feeling of her cum inside of me. It burned slightly. I push it it with a pop, the cold metal heavy and alien in comparison to the familiar and loving warmth of my sister’s cock.

Getting back to bed with a smile I make a note to myself to call my mother tomorrow morning to tell her all about Alyssa’s development.

I wake up groggy, and stumble out of bed at 10:21am, according to my nightstand clock anyway. I glance over at Alyssa’s bed, to find her still collapsed in the bed, ass exposed to the world without a care. I grin, then figured to let her sleep while I prepare breakfast before summer school in the afternoon.

I pull a pair of panties over my smooth butt cheeks, and a pair of sweats before walkingto the kitchen. I pause by the oven to grab an apron, and put it on. I still had the steel butt plug heavy in my ass. I hear the steps coming from the hallway leading. Alyssa comes, groggy eyed and hunched over. She smiles at me sleepily and takes a seat on the crunch next to the bar island.

“What is it darling?” I call over my shoulder, pourring orange juice into two cups.

“Morning bro.” She calls out, texting on her phone.

I come over to the couch and take a seat next to her with a tray, both of our breakfasts on it. Two croissants, two toasted peanut and butter sandwiches, two cups of orange juice.

After we finish breakfast, I send Alyssa off to school and sit back down on the couch, take out my laptop and open it. I have a few hours before school starts, and have to call my mom.
