Rei just sat there, hoping Nagisa would just let it go. But Nagisa was not going to, he would do anything to see Rei's cock, and that was that. "Rei as your professor I am TELLING YOU TO MASTURBATE!" Rei's eyes widened, he knew he loved Nagisa. He wanted to show Nagisa how he felt… But was afraid Nagisa would hate him forever if he said anything. Rei shyly slid down his pants. Nagisa smiled. He could not wait to have Rei inside of him, but he would wait for the final test. "Wow Rei-chan! That's a nice piece of meat there!" Nagisa teased. Rei slowly took his member into his hands, and began pumping. Rei usually masturbated over Nagisa, imagining how it would feel to be inside of his small body. Rei closed his eyes and thought of Nagisa. He began to pump faster, moaning louder and louder. It felt so good, but it would feel better inside Nagisa's ass. Rei came, sticky white fluid erupting from his penis. "Yay! Rei-chan you came...A lot…!" Nagisa clapped. He had never seen Rei that way, mouth open in pleasure, he looked so sexy!
"Now Rei, we have to practise hand-jobs on other people! That was just a warm up to get us both excited. Also so I found out how good you were at wanking." Nagisa smiled wider than ever, now he could touch Rei, where he'd always wanted to. In ways he'd always wanted to. "Lay down Rei!" Rei laid down, unaware that Nagisa was squirting lube onto his hands. With Nagisa fingers oiled up, he wrapped them around Rei's hard dick. Rei's eyes opened wide in shock. "Nagisa-kun, what are you doing?" "Rei, I'm giving you a hand-job! I want to teach you this way. You don't mind, do you...?" Rei blushed, he loved Nagisa. "N-No, go ahead…" Nagisa pumped faster, and Rei began moaning. Nagisa's hand felt so good on his cock. Rei looked up at Nagisa, eyes filled with lust. "Does that feel good Rei-chan?" "Yessss, faster please. I'm c-c-c-coming!" Rei came all over Nagisa's hand, cum dripping onto Nagisa's bed sheets. "My, my Rei, what a mess you've made." Nagisa said seductively as he licked his fingers clean. "Wow Rei, you taste good too!"
Later that night Rei was jogging home. He couldn't stop thinking about Nagisa. Did Nagisa love him? Would he pleasure him like that if he didn't? Rei knew he loved Nagisa, he just wanted to know if the feeling was mutual. Rei lay in bed that night thinking of Nagisa's 'Sex education' lesson. He wondered what Him and Nagisa would be doing in further lessons, the though made Rei excited. He couldn't wait to find out!
The next day after practise, Rei and Nagisa were walking back to Nagisa's house, for the second lesson of sex ed. When they reached Nagisa's house they went straight to Nagisa's bedroom. "Let lesson two of Professor Nagisa's sex class begin! Today we learn about oral sex!" Rei blushed, but was excited at the same time. Would he get to taste Nagisa now?
"Have you ever given or received a blowjob before, Rei-chan?"
"No" Rei blushed deeper red.
"Would you like me to show you?" Nagisa crawled on the bed and got close to Rei, staring at him. Before Rei could answer, Nagisa was taking off Rei's trousers. Rei laid back, giving Nagisa easier access. Rei was large, so Nagisa couldn't fit him all in his mouth. But he began sucking, and swirling his tongue around the tip of Rei's erection. Rei had never felt so much pleasure before. The wet sensation of Nagisa's mouth was almost too much to bear. Rei came into Nagisa's mouth, and Nagisa greedily gulped it all down.
"Now it's your turn to show me what you've learnt Rei!" Nagisa laid back, with his fully erect penis in full view. Rei's moans had got him hard.
"I'll make you cum Nagisa. I promise to please you!" Rei put as much as Nagisa's member in his mouth as he could. He began to move his head up and down. Swirling his tongue, like Nagisa did. Nagisa's moans really turned Rei on. He wanted Nagisa, as soon as he could.
"R-Rei-chan…." Nagisa breathed. It felt so good. "Rei I'm coming, I'm coming! Please, don't stop…" Nagisa came, so much that some of it poured from Rei's mouth. Rei swallowed as much as he could. They both fell asleep next to each other. Both of them smiling happily.
