"Aaaah" he cried as he ran her up and down, alternating between smooth and rough movements.
Potemayo was now visibly terrified and wet herself all over his penis and crotch area. While he enjoyed the feeling of the warm liquid cascading onto his groin, he had been urinated on and saw this as a grave insult.
He picked her up and stabbed at her with his erect penis, causing further cries of fear from his pink haired captive. Mudo then noticed the source of the previous urination, which must be the equivalent of a vagina for a human. It was still trickling urine.
Slowly, he lifted her up again, then began lowering her onto his waiting cock. Potemayo began thrashing to escape, knowing that something bad was going to happen, but it was no use. Mudo's human hands were much stronger than Potemayo.
"I wonder if it will fit" Mudo asked himself as he lay poised to enter his class's mascot creature.
In one swift movement, he brought her down onto his penis, entering her opening roughly. He had no lubricant, and thus it was not an easy fit, and Mudo was sure he felt tearing and rupturing on his way in.
Potemayo let out a screech of agony as the foreign object which was Mudo's penis buried itself deep inside her. Never had she been in such pain.
After a short time of getting used to his situation, where the only thing that happened were more cries from Potemayo, he began thrusting into her. Holding her in place by her arms with his hands, he lifted her up and thrust into her, savouring her tightness around his penis. This carried on until he felt satisfied. He did not care that he was irrevocably damaging the innards of Potemayo, indeed, the pounding had made it easier to move around and the blood acted as a lubricant as it flowed down onto his shaft.
