Lube your cake cock. And push it inside your asshole. By now, you're probably all tight and relaxed, so I'm more than happy to take my time and watch you doing it with your pace. You are allowed to widen yourself with the carrot again if you have to. Is it a struggle? Life always is. Inserting a cake dildo is no exception, sweetheart.
Push it inside you until it vanishes completely. If you break the condom, you have to stop this tease and eat the filling. Better be careful!
