When I made that discovery I came again and the place in my balls was emptied but started to fill itself again. That way I could fuck until my body is exhausted, but my cock will always cum. The space enlarged itself from time to time and could hold more cum.
The demoness made me cum at least five times and the cum loads were a little bigger each load. Her face started to be filled with pleasure and it wasn't deadpan anymore. She let out some moans and her eyes rolled up. "I didn't think you would have such an endurance. I really underestimated you. You would make a good sex servant, even though you're a human. I won't kill you today by draining you empty." She did it again. She was talking nonsense again. I will maybe make her my sex slave. But I'm not going to be anybody's sex slave. But at the moment I could really do nothing. She said to the four demons, "Each one of you can get one load too. You better do your best, it's only going to be one." The one on my right leg was going first.
She changed places with the demoness and didn't fuck me, but sucked me. She started with licking and sucking my balls. It was refreshing, since I was dominated for an hour nonstop. I started to relax, but the peace didn't last long. Shortly after she worked herself up my shaft and her tongue was slightly longer that a human tongue. She wrapped her tongue around my shaft and moved up and down. Her siliva mixed with my precum and was dripping down. In comparison with the blowjobs from the schoolgirls this was heavenly. "My body is special and it's especially made for blowjobs. I bet you never had something this good, right?" She was right, but I couldn't answer, because I was in an ecstatic state.
