He drained to much blood to do anything

Feeling to light headed, you give into the batman. Sensing you have no will to fight back, he holds you tighter. You start to feel a growing erection on your stomach and bits down on you hard to keep you in place as he flys up and hangs upside down on the ceiling, rewrapping you with his wings. He then positions his dick on your ass, and then plunges in. He continues to drink your blood and fucking you at the same time. Normally the fat cock in your ass would be painful and making you scream, but the batman has drank to much of your blood for you to even give a reaction. He impales your ass hard and licks at the blood from your bite wound. He then starts to lick your lips giving you some affection and puts his blood covered tongue in your mouth. You can taste the metallic taste of your blood on your tongue as he sucks your tongue in his mouth and bites it to drink some more blood. He picks up the pace of fucking you, seems like drinking the blood from your tongue has turned him on more. Soon he cums deep into your ass, breeding your for awhile. Then you realize his cum is becoming a steady stream, realizing then he is peeing inside you. He continues to lap up your blood, seeing he has to do less work since your bleeding into his mouth, and replacing all the blood he is taking from you with his pee. After a while, you stop leaking out blood, and his bladder empties out. He then lets you drop to the ground dead.

You have died, but the bright side is. You gave a bat a good meal and even let him fuck you and became his toilet before you died. You did something good for him. To bad he won't remember it.
