My hand was steadily writing down word after word as I took great detail into the slime girl Tabitha, who was kind enough to volunteer in my studies. The blue slime was currently in a humanoid forme, something common with slimes these days. She saw an ad I had placed in the middle of town for some experiments and called this morning to see if this was still available. Thankfully it was and I have been running tests on her as well as I have been curious on how a slime really works. There have been many different cases of slimes. Some that are just a pure mass, some that appear humanoid and or in a beastial forme. There are some that do both. Tabitha has been very cooperative with all the studies so far. Aside from one though, which involved sexual intercourse with my sister Shade. She was a little uneasy with having me watch as it felt weird. There were some questions we both had. Shade being more persistent with some focused on her kinks. Like if a slime can mold its body at will, could she theoretically pose as a virgin no matter what? Cause the way their body structure works is a more gelatinous material, so compared to a thin skinned membrane of an actual hymen, a slime would be more of a liquid. Tabitha was vastly confused on this but answered profusely about how she has had many partners beforehand. Though this comes to a point on how slimes breed. Cause in all technicality due to their body structure focusing around a single core, all slimes, regardless of gender, can breed. So long as seminal or eggs are injected near the slime core, they are capable to be bred by anything plausible. Though, this does not drop out the possibilities of forming special opening inside their slime to provide extra pleasure with their partners who are not slime. Case in point with Shade, we have Tabitha mold a "fully functional" vagina into her nether regions. Now, this is coming from me. Shade will enjoy a lot of things if she can find a way to knock it up. Believe me, she can. I remember her telling me about a possessed statue she ended up pinning against a wall and pumping a few loads of cum into her stone crevice. And I did some research about said statue and found a headline about one of the statues mysteriously changing to appear in stages of pregnancy. And for Tabitha, this will end the same way regardless. Her vagina molded well against Shade's cock as she thrusted into her and the stimulation she was receiving was because of how Tabitha was manipulating her own mucus membrane. In a way of muscle relaxants to prolonged exposure, she also influenced her slime to produce an aphrodisiac effect that brought my sister down on all fours when breeding Tabitha. The slime girl did jerk her head a bit and almost sunk Shade into her after when attempting to knot the slime girl, she pushed her cock in a bit further in than expected. Tabitha tried to adjust her womb a bit as the appendage pierced through her slimy cervix and accidentally angled it to where the tip of my sisters cock slammed into the makeshift fallopian tube and sunk in slowly. To say that stars formed in Tabitha's eyes were an understatement as it put her in slight shock for such penetration. Soon to be followed by a powerful cumshot from Shade and said tube expanded with her glowing mana drenched semen and bloated over the empty ovary canal. This currently proves to be a future study as normally a slime could digest the liquids, but the pocket of magical semen still now resides in the spot. Shade apologized profusely if she caused pain to Tabitha, but the slime girl was fine and said it was okay. She was just wondering what was gonna happen since she has the semen stored in her now. From what we were looking at, it seemed to have settled down a bit as it resided in the canal, but from what I was looking at. It could be a possibility that Shade ended up creating a new core inside Tabitha by accident. It is one thing that Shade would have impregnated the slime girl in question, but to full on create a new core inside her? This is where future studies are needed to see what happens to Tabitha. Would the new core become hers, or will she give birth to a new type of slime? We have come to an agreement to have Tabitha stay in our guest room should she need it, especially if she were to start feeling extra strange from certain after effects from the experience. Wouldn't want her to suddenly hurt herself from any spells being cast out of nowhere.
