Zach was both excited and worried. He was excited to have Colin shag him in what was likely to feel more than simply shagging. No, Zach felt it - knew it wasn't the same thing. He hadn't really done that before. He hadn't...with Cedric. And he hadn't fallen in love again before Colin. Zach wasn't sure how exactly love affected it, but he knew it would. However, Colin was so new to it, knew so little. And Zach wanted to do it...right.
And the shock of everything Colin was saying and talking about sex had wiped everything else from his mind. If he were busy being all...whatever, he wouldn't be doing it right by Colin, wouldn't be helping enough.
"Yes," Zach caressed Colin's face, "Some books assume you know some stuff. I think I've got some stuff somewhere about sex between men, from before I knew much." He had known more than Colin, but the pamphlets and stuff hadn't assumed that. "We can stop if you ever want to, okay?" Zach looked more serious, "Promise me you'll ask me, us, to stop if you want to. It's most important to me that you want it, with me..." Otherwise he just couldn't, not in his right mind or not right mind as he were right then.
