Shinichi woke up in the middle of the night, rubbing his eyes to wake himself up. He picked up his glasses and looked over at his alarm clock. The digital red numbers read 3:09 AM, way too early to wake up for the day. Wondering what had woken him up, he looked at his right hand, seeing Migi was asleep. He was confused as to why he woke so suddenly. He wasn't having a nightmare. He was having a pretty nice dream, really. Looking down, he noticed a tent in his boxers. Problem solved.
Now to fix the other problem. He hadn't even thought about jerking off after Migi took control of his hand. Shinichi was right handed, and he was awful at using his left hand. He examined his right hand again, looking at it closely.
It was just his hand. If he didn't know that Migi was asleep inside it, he would've thought it was only just his hand. Shinichi fell asleep before Migi, and Migi usually slept for a few hours…
"Eugh...gross..." The thought of using his parasite-infested hand made him nearly gag. In the same thought, he only became more aroused. Looking again at the clock, it was now 3:12 AM. He had fallen asleep around one, so Migi should be asleep for at least another hour.
“I need to get this over with before…” Shinichi shook Migi out of his thoughts in order to save his boner. With a sigh, he pushed his boxers down to his ankles and kicked them off, reaching down and rubbing his cock until it reached its full length. His body relaxed and he moved his hand, slowly stroking up and down. His desperation was obvious when he quickly started moaning and leaking precum.
He was keeping a slow and steady pace, enjoying the quiet pleasure after the past few days. Given it was a little difficult because of his lack of complete control in his hand, he moved a little faster, his breathing steadily increasing with haste.
It was then, amidst Shinichi’s panting and sweating that his hand seemed to gain a mind of its own. It rubbed in all the right places, his fingers seemed to be lighter and warmer, as if his palm had molded into something else. Finally, with a sudden growth in pace, he felt himself reaching orgasm. Cum shot from his cock to his bare legs and the clean sheets.
He laid back, his breathing returning to normal, until he felt something wet on his fingers.
“Wh-What is…” He looked down, his first thought being about blood. He saw his fingertips stretched out and they seemed to be examining the result of his orgasm.
“So this is human sperm.” Shinichi’s face flushed, a deep red tinting his skin.
“When did y-you-”
“Your increased heart rate caused me to wake up. I’m not sure I understand. What is the point of ejactulation when not into the sex organ of the opposite sex? In my readings, I found no other use of the sex organs than breeding,” Migi’s voice sounded curious, not at all uncomfortable or awkward. Shinichi attempted to give an answer the same way, but his discomfort was overpowering. Taking a deep breath, he mumbled.
“It, uh, feels good.”
“You sounded as if you were in pain,” referring to Shinichi’s moaning and panting. He tried to think of a response, but stayed silent.
“Do all humans do this? If it hurt, why would you? Are you a masochist?” Shinichi almost choked on the words coming from his hand. Migi was perplexed by human sexual nature, and simply asked questions.
“Um, I guess pain and pleasure have similar reactions?” He sounded unsure and wanted to wake up from this living nightmare. Shinichi would much rather be asleep, thinking about being chased by the undead, but instead he was having the talk with his right hand.
“I have no concept of pleasure,” was all Migi said.
“Going back to sleep, try not to wake me again.” Shinichi watched as his hand became his hand again before getting up and quickly taking a shower. He stripped his sheets, hoping he wouldn’t wake anyone.
He laid back down, glancing at the clock before removing his glasses and falling asleep.
3:48 AM.
