You seem like a prime candidate for an egg bed...

Finally, the tendrils thrusting stopped. My body buzzed with alien euphoria as they pulled back. Down my throat, out my stomach, and through most of my intestines, finally coming to rest in my colon, still lightly pumping ooze the whole way. I coughed, expelling some of the plant's precious cum from my throat. Finally able to inhale, I took in a deep breath, swelling my lungs. I felt as though I could burst, completely full of the plant's seed.

"Ugh, fuuuuck," I groaned between coughs as the plant retracted its tendrils from my face, "that... was..."

No words in my language were adequate, so I just shook my head, trying to clear the haze. This might be the end of the plant's plans for me, but I didn't want to hang around and find out. I already felt like I was carrying twins, so I needed to get out before it went too far.

I started by unraveling the limp tendrils from my legs. When I reached around to start pulling them from my ass, the resisted my tugging. Energy suddenly returned to them. I tried to stop them, but it was futile. There came movement coming from the ground where the plant had been. I looked over my shoulder and saw a much larger vine extending from the earth. It was thick, like a fat snake, and it was reaching for me.

"Okay, so it definitely hides... further... tools underground," I chuckled nervously to myself.

The tendrils were rather small but impressive little things, especially when united. As I was thinking of them, they withdrew most of their length, stopping at my entrance. Then, they pulled apart from each other, stretching my hole wide, spewing a small fountain of ooze from my ass, seemingly preparing it for this new member of the party.

I watched with a mix of fear and excitement as the new vine kept extending itself, finally reaching the edge of my lower entrance. Then, it plugged my leaking hole with its head, slowly pushing its way into me using its own seed as lube. I was still too tight for such a size, but it slowly stretched my ring open anyway. It was easily 10 times bigger than the other tendrils that had been using my body, so the pain returned.

"Oh, fuc- ouch... ow ow ow- oH FuCK, PLEASE!" I instinctively cried out words that would change nothing. I whimpered as the new tendril continued to stretch me, boring deeper, but it didn't stop. It still hurt, but my elixir was doing its job nicely, transmuting much of the pain straight into pleasure.

Finally, the tendril pushed all the way into my colon. It reached the pool of cum that the tendrils had just splattered my insides with; and finally stopped. It didn't seem to be doing anything at first, so I took the moment to slow my breathing. This may have been a bit more than I had bargained for. Without warning, the bigger plant tentacle hardened, once again stretching me.

"Ffffuuuu..." my voice faded as my eyes met a huge bulge in the vine slowly making its way from the base of plant, towards my ass. There was no way that would fit, "Oh gods... what? That can't be what it looks like."

I only managed a whisper, knowing there was nothing I could do to stop the large, fist-sized egg from flowing down the tentacle. It pushed between the meager resistance my legs were instinctually presenting and arrived at my ass. It paused for a moment, gingerly testing my tightness, probably making sure I wasn't capable of breaking the precious goods.

"Oh gods," I repeated as the vine probed. At last, it pressed. I bit my lip and clenched my fists, trying to hold off the agony. The egg stretched me further than I ever intended for my ass to open, pushing its way past my sphincter and fully into my butt. Once it was passed my anus, it was actually quite pleasant. I could feel it moving ever so slowly deeper into my guts, eventually reaching my colon. There, it reached the end of the tentacle, and I felt it plop inside.

"So... that's what... that's for..." I panted, realizing that this plant was going to use my bowels as an incubator for its offspring. As I finally began to catch my breath, another shape began moving its way up the vine. And another. And another. More. So much more!

I let out a low moan as the tendrils keeping me open stretched me once more, preparing my anus for more eggs, "N- no waayy..."

Before I could find the strength to struggle, the second egg reached my ass. It was less painful than the first, but I bit down on my lip again, harder this time, trying to stifle the pain, and tasted blood on my tongue. Now the third, I still had to clench my teeth and release squeaks of pain as it passed my barrier. It slipped past as well. The fourth, it was almost tolerable now, my muscles jerked in pain as it entered, but I couldn't help releasing a lewd "Aaanh!" from my lips.

My stomach was swelling of course, now looking halfway done with a normal pregnancy. Five. Six. Seven. The pain was almost gone, replaced by lighting strikes of bliss every time a new egg entered.

The tenth egg finally reached my stomach, and I knew I was about to lose it. I bit down on my lip again, but it didn't help. The egg pushed deeper, and I could feel it shifting around the others inside me. My belly was starting to expand beyond its limit like I was on the verge of giving birth. Thankfully, the injection from the red tendril earlier had seemingly increased the elasticity of my skin.

The tentacle that had been inside me for so long suddenly stopped its insertions, and I felt the egg inside me move as it switched to pushing them in further. My entire colon was going to be used as an incubation chamber for the young of this bizarre plant.

"No more..." I panted, "Please... If you keep going, I'm gonna split open..."

I prepared for an additional egg, it was about time for another, but it didn't come. Instead, it felt like the tentacle inside me was just positioning them in different parts of my insides for optimal fertilization. It didn't feel like the plant was playing with me, just that it was caring for its offspring.

I let out a cautious sigh, "Are.. you just about done...?"
