I was hanging out with my shark buddy when he told me about a wish he had. We had always played around with each other, but what he was suggesting was more involved than usual. With a big saw he had bought in case he could convince someone to go along with it, we took turns sawing the other's head off. He did it to me, and then I had to blindly do it to him, but it wasn't all that difficult, with him guiding me. With our heads off we couldn't speak to or see each other, but we had said everything that needed to be said beforehand. I laid down on a table, he was already rock hard when he had seen my freshly-severed neck. He slid his penis into my throat, careful not to block my windpipe. This way he had sex with my severed neck until it suited him. It hurt and I could not derive much pleasure from it myself, but he told me afterwards that it was much better than a blowjob, that's for sure. I didn't do it to him, but I did find myself curiously rubbing my cock against his neck and we tried to 'kiss' with our neck stumps. After we both enjoyed feeling each other out with our heads missing we figured it was time to pack things up. He took my head and sewed it back on, and I did the same to him afterwards. Not a trace was left on my body, as I'm covered in feathers, but to this day you can still see a faint pinkish grey line around his neck.
