"You know," James smiled sarcastically at Yuma. "In the process, using ECI serum must also be accompanied by the use of other serums that support the function of ECI serum."
"What is that supposed to mean?" Suddenly Yuma shivered, there is something more terrifying here, he thought.
Meanwhile, Ivy kept wailing because she didn't know what else to do or what to say to get James to stop all the madness. She already knew what James would do to Yuma after she found out about the serum that was injected into Yuma earlier. And it was terrible for her even just to imagine.
"It means," said the female officer, standing to Yuma's left. "Without another serum, you will feel excruciating pain after the third, fourth orgasm, and beyond that you have."
Yuma gasped, he was at a loss for words at the craziness those people would do to his body. He looked up at Ivy, and the pain was deepening in his heart.
