I don't know about any magic tricks. The lubrication that the two of you make together. Tossin' a good salad always does wonders. Try to imagine more what anal sex felt like to. If you can imagine the sensation & hold on to it that might help with some anxiety. I don't think your beau will kill you with his cock. Obviously, nearly 10 inches is a lot of dick to try & take but he knows that. Just trying sliding it in slowly. Try to swallow his cock with your ass. Use all of the lube that you can find. I think it'll be best though to let him break you again rather than using a toy. It'll be more fun, you know? Maybe. I'm speaking on my tastes for the situation.

Please try to take him as much as you can. I'd hate for him to be deprived any longer, especially if you wanna give it to him. Good luck. I'll pray for your internal organs. I'm just kidding
