Tadaomi frighten a bit when he heard the other male's words. He would die of shame if the creature were to find out that he was ... actually involved in it. Koro sensei smirked reaching a tentacle to the other's entrance, the same let out a light moan as he felt the tentacle rubbing against his hole. When the yellow malepushed the tentacle in the creature stood surprised for a bit as he felt a soft meat clenching into one of his limbs like crazy, "Haha, don't tell me... Karasuma sensei fingers himself ? Amusing indeed".
The sports teacher only blushed at the question, "Ah, I'll take that as a yes then". The other male was getting slightly annoyed with the boring silence in the room, he didn't wanted to have fun all by himself, so to stir up the other teacher a little bit he suddenly stuffed one more tentacle in. With the sudden feeling of the second limb entering him, Tadaomi quivered and let out a loud moan. Koro sensei could only grin widely as he heard the sport's teacher sweet voice enter his eardrums, he wanted to hear it once again so he forcely pushed a third tentacle in, all he could feel was the quivers from the man bellow him "Agh! Ngh-ih!", 'Ah... Music to my ears...' the creature thought.
But there was still one thing he hadn't done yet, he was dying to try it right away so, to fullfil his own desires he began to move the three tentacles wilder and deeper trying to find Karasuma's sweet spot. When Tadaomi sensed the limbs hitting deep inside him, he jolted back gasping for air while tears began to well up in his eyes from the sudden intense pain "Ngh! Sto—ngh! Ih! I'm ah! Gha! Gonna ... ah ... break—ngh!". The octupus teacher tried to find the other's prostate as fast as he could, he did not wished to cause pain to the other male. In a fraction of seconds he felt one of his tentacles hit a squishy yet soft meat and as soon as he felt that he fastly moved the other limbs to the same place, "Say Karasuma sensei, is it here? Is it here that you feel good?".
When the yellow creature stopped talking a red string of blood started to fall out from his own nose as he suddenly saw the other man's state. Tadaomi sensei couldn't even say a word with the pain that now had faid to unbearable pleasure hitting deep inside him, the only think he could do was moan sweetly at the sensation of his prostate being stimulated over and over again. "Hoho, it looks like you're feeling quite good alright... Karasuma sensei... I didn't knew you could be so lewd hehe", the alien began to hear mumbles coming from the other's mouth, so he gently curled a tentacle around his chin and whispered "Talk a little louder, please ?". The sports teacher's face was a mess, his eyes were all blurry and the saliva rolling out from his mouth seemed like it didn't had an end.
"M-more ... ngh .... more"
The octupus teacher couldn't believe in what he was hearing, it was too good to be true, "I still can't hear you". Tadaomi just wanted more pleasure, and he wasn't gonna play hard now that his climax was approaching. Instead he started to move his own hips feeling the other's limbs going in and out of his horny hole, "Ngh ... I want ... to come... ah!", the creature smirked when he headr the other's plea "Oh? ... I see, I'll let you come since you're being a good boy, but ..." Koro sensei suddenly replaced the three limbs by a thicker and longer one "... you're gonna have to make me feel good too ..."the sudden action made the other man jolt back in pleasure once again.
'No way... Is this his dick? So thick and long, fucking disgusting ...' Karasuma's thoughts were contradicting is actions. He now moved his hips faster than before trying to hit his climax as soon as he could, but now there was something stopping him ... a tentacle, a tentacle was wrapped around the base of his cock preventing him from coming, "Now... Karasuma sensei... don't you think you're being a little selfish?... I just put mine in... don't be mean now". 'Mean? You're the one who's fucking raping me and you're calling me mean? Seriously I don't know what's up in your head'.
In a moment there was a big rockus and when the black haired man opened his eyes he found himself facing the alien quite straightfully, he hated that grin, he couldn't look at his face up so close, not in that moment. He tried to hid his face with his arm when suddenly a tentacle coming from nowhere stopped him from doing so pushing his arms on the wall behind him. "Come on, you can't have all the fun to yourself", the sports teacher frowned at the other's words, "And .. ngh .. who said I was having-ah .. fun .. jackass!". The octupus teacher chuckled at the others reply "Haha, your body sure doesn't thinks that ... why don't you submit to me and cry out some more Karasuma sensei ..." as he said this he reached his tongue to lick the other's ear and began to fasten up his moves.
Tadaomi moaned at the sudden feeling, he couldn't surpress himself anymore, "Please ... ngh ... Koro sensei" the creature smiled at the other's words also feeling his climax approaching, "Haha, well that's a cute Karasuma sensei". As soon as the alien released the other's member, he saw a white liquid shooting to his clothes dripping a bit to the releasor's belly. Koro sensei grabbed the sports teacher limp body as he noticed he had pass out from the exaustion, still, it wasn't enough to satisfy the alien's needs.
He wasn't that mean to continue his amusing time with a limp body nor to leave him alone like that, so, he grabbed the other teacher by his limbs and headed to the other's apartment. Luckily Tadaomi had left the key in his jacket pocket, so with that the creature opened the door. He then cleaned the black haired man, dressed him with his pajamas and placed him on his bed. He looked at the other's sleeping face and gave one last smirk before leaving the building 'That look will soon be mine'.
