It didn’t start sucking as I expected though. It did something else entirely, I couldn’t figure out what for the life of me, but it somehow felt as though it was entering my clit. The worm slowly flattened its tip against me, and I suddenly started to feel really weird down there. I was then pretty sure I could feel something small and thin then making its way into my urethra, but I couldn’t be sure. It detached itself from my thigh and simply hung limp between my legs, still firmly attached to my clit and the area surrounding it.
The weird feeling became more pronounced as I noticed the worm begin to change colour, and though the sensation was slow to come on, it was in an instant that I realised that I was starting to FEEL the worm, as if it was a part of my body. It was now the same hue as my own flesh, more or less, and it raised itself up, the end not attached to me swelling up as it went.
There was no mistaking what the worm now looked like. While I had always perceived them in the same way as I did a penis, it now genuinely resembled one. A really fucking big one. And it was mine. I could actually feel it when I reached down to touch it. The tip, which had swelled into a very cock-like head, was as sensitive as my clit. I shivered at the sensation, and then noticed Hannah, who had seen the whole thing. Her mouth gaping, her eyes had a look of unbridled lust. She couldn’t believe what she was seeing, but she loved the sight.
She crawled over to me til her face was mere inches from my new cock, and looked up at me wide eyed and horny. “Can I… can I have that?” she asked, quivering.
“All yours lil sis.” I replied. With that she licked it, getting a good taste of the fluid that was leaking from the hole at the tip. Her eyes lit up and she started licking more, the feeling of her tongue playing with my cock was heavenly. She wrapped her lips around it, and tried to suck as much of it into her mouth as she could. It was too thick for her to get much in, but she continued sucking the fluid from its hole and making my knees quake.
My legs just couldn’t handle the amazing sensations she was causing, and I slowly sank to the ground, Hannah’s mouth hungrily following my cock until I was fully laying down, sighing as I felt the mass of worms beneath me massaging my back. She quickly settled into our new position and wildly slurped and sucked on my cock.
“Mmm, tastes so good.” she sighed between sucks, then started bobbing her head up and down on the small part of the head she could fit into her mouth. “But I want it deeper inside me.” Hannah looked up at me, her eyes full of lust.
“Then come here.” I said, and reached down to pull her face up to mine. As soon as our lips met, our mouths practically fused together. I loved the feeling of my tongue in her mouth, hers in mine, and when they met in between. I could feel her pussy against the shaft of my cock, and she grinded against it as we kissed with intense passion. I felt it move a bit, and though I couldn’t quite tell what was going on down there, Hannah lifted her hips up a bit and before I knew it, I could feel her pussy slowly start to open up around my cock.
Hannah sat up on me and started wiggling her hips to try to force my cock deeper into her insanely tight pussy. The head had barely entered her when I felt it come up against a barrier that I knew to be her hymen. Hannah jolted from a sudden feeling of pain, but then cautiously started to put more and more weight onto me. And then, as if she suddenly stopped giving a shit, she lifted her knees enough to put ALL her weight on my cock. Her scream pierced my ears as the whole head suddenly popped in and began a slow descent into her pussy. I couldn’t tell if it was a scream of pain or pleasure, but she kept forcing herself lower and lower onto my cock regardless.
We locked eyes as she descended and she grabbed my head, pulling my mouth to hers. My own hands traced random patterns across her back, hoping to add a little tenderness to this intense, raw passion that was electric between us. It was futile though, because I soon found my hands at her lower back, pulling our crotches together as hard as I could.
I wasn’t sure how long my cock was, maybe a foot, maybe more, but it was a little over half way buried in her pussy when it met her cervix. Did I mention how tight her pussy was? It bears repeating. Being inside her felt like trying to put on pants several sizes too small. But then I felt her cervix quivering and it was almost too much. She started lifting herself up and dropping down, gasping at each impact as my cock slammed against her cervix.
“I need more Amy!” she whined. “Fuck that thing right into me!”
Well, if she insisted. It took us a couple of seconds, but we quickly found a rhythm so her downward motions were met with my upward thrusts. Each impact sent shivers up my spine which spread across my whole body, but I could feel it going a tiny bit deeper each time. Her cervix was soon open enough to allow a bit of the tip of my cock past it, but all it took was one, final thrust for it to pop in, at which point she suddenly stopped, arching her back and staring at the ceiling, mouth agape.
Her body seemed paralysed, and I just sat there and watched her sink lower and lower onto my cock. I felt the back of her womb stretching around it as her pussy consumed the final couple of inches. She was still in the same posture, just letting out one big, long sigh as she grew accustomed to being stretched so wide, and penetrated so deep.
She slowly started rocking her hips back and forth, building up intensity until she was frantically bouncing up and down on my cock. Her boobs were still leaking milk, which also covered my own chest, and I couldn’t help but reach up to play with them as she rode me. When I felt that she was definitely used to having me inside her, I began thrusting. She couldn’t keep up with me, and soon she stopped moving at all as I started really pounding into her.
“FUCK FUCK FUCK!” was all Hannah could scream as I fucked her harder and harder. Her tits bounced with each thrust. Her pussy was stretched so wide around my cock, it looked so incredibly hot and I couldn’t imagine how good she must have been feeling. It felt pretty amazing to me too, but it was such an unfamiliar sensation. I could feel her pussy squeezing every inch of my cock as I thrust into her just far enough to leave only the head in her womb.
I could feel something welling up inside me, something I’d never felt before. I didn’t really know what it meant, but with it my cock seemed to become more and more sensitive. Then I felt a worm pushing its way between my buttcheeks and up against my ass. It wasn’t gentle, but it didn’t hurt as it forced my tight hole open and wiggled its way in, deeper and deeper. It then stiffened, refusing to move with me, so instead, I moved against it as I thrust hard into Hannah. Just as I fucked her, I fucked it.
Hannah was going wild atop me, screaming and babbling incoherently as she was utterly overcome with pleasure. I grabbed her buttcheeks and held her in place and deepened my thrusts. I inched my fingers closer to her butthole all the while, before finally finding it and teasing it with my fingers. As if I’d pushed a button, that set her right off. I felt her pussy spasming all over my cock, as the worm in my ass suddenly seemed to swell up to nearly twice its size.
Hannah and I then came together, and I felt myself shooting a huge amount of liquid deep into her womb as her pussy massaged my cock. This liquid seemed to be coming from inside though, not from the worm that had attached itself to me. I grabbed onto her back and pulled her close, and she fell onto me, her engorged boobs pressing tight against my body. I gasped in shock as I felt the worm in my ass start popping out… over and over again. I quickly realised that it had become ‘ribbed for my pleasure’, and with perfect timing it pulled each section out of me, making my ass stretch and contract as it went.
I felt like the two of us were now just a pile of orgasms, and my ejaculation continued unabated. Hannah shivered on top of me as her entire system was wracked by the greatest things she had ever felt. Despite how lost I was in this orgasmic delirium, I couldn’t help but notice that her pussy seemed to be slowly sliding off my cock. I moved my hands back down to her butt, and noticed that it was a lot higher than it was just before.
The realisation that I was shooting so much cum into her that her stomach was being forced to expand to contain it all seemed to get me shooting into her even harder. I could swear I could even hear it splashing against the walls of her womb. I found myself suddenly sitting up, so that she was now in my lap, and the worm in my ass now bore all my weight, which made its journey out of me even more incredible. I then pushed Hannah down onto her back. The bulge in her stomach was now quite easy to see, and I couldn’t help staring at it growing bigger and bigger as I kept unloading into her.
I don’t know how long this took, it’s hard to keep track of time when you’re so overloaded with ecstasy you’re barely aware you even exist, but I could see her stomach swell more and more with each great spurt. By the time I was done, she looked heavily pregnant. Not as big as I’d ended up before, but maybe about 8 months along.
I let out a long, deep exhalation when the worm in my ass finally exited all the way, and my torrent of cum finally died down. I took a moment to admire my handiwork. Hannah’s huge boobs contrasted nicely with her now huge tummy, and the look on her face was one of total contentment and satisfaction. I wiggled my hips, trying to squeeze out every last drop of cum, and then suddenly I found that I could no longer feel my cock. Still buried deep inside my little sister, I watched it detach itself from my clit and started worming its way deeper into her pussy until it disappeared altogether.
It had a pretty big effect on Hannah though, as she quite obviously started cumming again. Looking down at her, I then noticed that my own stomach was now as flat as it had been before this whole thing started. It occurred to me that maybe the worm had somehow used all the eggshells inside me to help create the huge amount of cum I’d just unloaded. How efficient! I was honestly just glad to have them out of me either way, though I felt an odd urge to see my tummy all swollen again.
