Boku no Hero Academia: Izuku's Harem Academia
Disclaimer: This is amature-rated fanfiction story of Boku no Hero Academiathat I am writing for erotic fun. Needless to say, this story is AU, the characters may seem OOC to some and there will be smutty lemons. Also, I own nothing of the series other than the fanfiction stories that I make.
Chapter 3: Sumomo and Tooru
Izuku woke up from his slumber and was glad that he had Sumomo with him to keep him company as he hated the idea of waking up alone after spending two nights with Ochako and Tsuyu. He smiled affectionately at the cute ball of slime and stroked it gently, causing it to quiver in response. Sumomo soon woke up and looked up at him with a sleepy look on its "face". The slime girl then woke up fully and had a mischievous look in its eyes before it suddenly rushed into his pants.
Barely keeping himself from crying out in panic, Izuku whispered, "W-what are you doing, Sumomo-chan?"
Izuku got his answer soon enough as something warm and slimy suddenly engulfed his morning wood and even started to ooze through his urethra to reach his bladder and prostate. He quickly covered his own mouth with his hands to stop himself from gasping in pleasure while his whole body shivered and shook due to Sumomo's apparent attempt to give him her own version of fellatio. He could feel Sumomo's slimy appendage moving in and out of his urethra while the rest of her slime-like body stroked and massaged the glans of his phallus.
Normally, insertion of a foreign object into the urethra has to be done carefully to prevent urinal incontinence, damaging the urethra and infections. However, since Sumomo's soft and slimy appendage could change shape to perfectly fit into Izuku's urethra without causing harm to it, Izuku felt little to no discomfort as he felt new sensations which he did not even realise were possible.
"N-not even Tsuyu-chan can do something crazy like this!" thought Izuku.
As for Sumomo, due to being comfortable with being her true slime girl self with not only Izuku but also Ochako and Tsuyu, she was perfectly happy to make use of her increased physical and mental freedom to pleasure all three of them in her own way. Indeed, just as Sumomo was pleasuring Izuku's member with her slime-like body, her physical copies did their own versions of cunnilingus on both Ochako and Tsuyu. Both girls were rendered helpless as their respective physical copies of Sumomo started to insert themselves into their increasingly moist nether parts to the point of oozing into their very wombs. Ochako and Tsuyu's sexual pleasure only grew as Sumomo started to stroke and massage their erect clitorises and even insert narrow slimy probes into their urethras to stimulate them. Before long, Izuku started to stroke his own penis while Ochako and Tsuyu fingered their own private parts to bring themselves to orgasm.
It should be noted that, due to past trauma involving a former host who had a fetish for excrement, Sumomo stayed clear of their anuses.
Due to the intense sensations on not only his phallus but also the urethra of the said phallus, Izuku quickly climaxed which caused Sumomo's body to swell with his white seed. While Izuku breathed heavily to recover from the intense orgasm, Sumomo slowly oozed out of his still-erect member and reformed into it's previous state as a cute-looking ball of slime. Speaking of climaxes, Ochako and Tsuyu also climaxed and each copy of Sumomo fed on their expelled vaginal fluids.
After Izuku caught his breath, he noticed something off about Sumomo and asked, "Sumomo-chan, is it just me or are you changing?" Although Sumomo still appeared as a cute-looking ball of slime, it was apparent that she not only had "eyelashes" just like the previous night but even had round bright-pink blushes on her "cheeks" and a small fold which formed a cat-like "mouth".
