Getting the hang of taking it in the ass

Amateur dude is trying to get the hang of taking it in the ass and it's not going well. He's been trying for a while now and his girlfriend is getting impatient. She's a sex worker and she's supposed to be on her knees, but she's standing up because she can't take it anymore. He's got his pants down and his ass is exposed, but she's not even looking at it. She's just staring at him with this mix of frustration and disgust. He's moaning and grunting as he tries to push his cock into her anus, but it's clear he's not doing it right. The girl is petite and she's not into rough sex, but he's forcing her to take it anyway. She's not even crying, she's just numb. The video ends with a cumshot on her big ass, but it's not enough to make up for the rough and hardcore shit that came before.
