You and karma never really got Along. Despite being in the same class and having yo collarborate to kill koro-sensei, you guys didnt care.
He and you were always taunting the other for everythings, just to be annoying. Specialy you. He was Mocking you on simple things and simply getting on your nerves for His only pleasure. Wich you only retorted even worst
*One Day, you and him practiced your attacks on each other to attack koro-sensei. And karma got you good. Like Normal, you would have Dodged all of His attacks and you Will be ending with a sore back from getting pinned down by him. And thats what happened today again. But you got a sore stomatch because if that.
Because of that, he took care of you . He was pretty persistent and didnt give Up wich ended by actually taking care of you.
After healing your scratch and patching you Up, you started to whine about how your back was hunting because of it, blablabla, just getting on His nerves.
At some point, he got Mad and snapped saying that he Will give you a back massage. You smirked, taking this chance to humiliate him if His massage was bad.
So There you were, laying on your stomatch on a bed of the Nursery Room with karma on your back, His legs on you sides as he was massaging your back.
His hands were slim, long and warm, massaging and going around your back as you were laying down. He was actually quite skilled at that, His hands hitting all the good spots in a very pleasurable way.
