Amateur anal sex - She's in pain

The woman gives him a blow job and starts to worry when the man's dick doesn't stop growing. They had already talked about having anal sex but she didn't count on the fact that the man has a big dick. With the hard dick she gets into a doggy position and the man puts the pot in her ass. She screams in pain and the man applies lubricant to her dick but she feels the dick is in the middle. The man fucks her ass until her ass is oozing with sperm.
