She frowned a little when he called her filthy, but it didn't last long as he started fingering her asshole. She twitched a little as his fingers went in, testing her for his manhood. At first she thought it wouldn't be so bad, that it wouldn't hurt as much as when he went inside her womanhood the first time.
Boy was she wrong. The asshole is not meant to have things go UP inside it. It was three times as tight as her pussy. That meant it hurt three times as much when he went up her. She was grateful that he was going gently, because as he pumped her, she found the pain being replaced with pleasure.
A small tear dripped down her eye when he first went in her due to the pain, but as he continued, that tear became long forgotten. Her asshole began to stretch as it tore around her hole. "OH KAMI! It's so TIGHT!" She screamed before shoving her face into her loves shoulder, biting softly into it. But she didn't relent. As he pumped up her, she would squeeze around him. pulling and holding him inside, as if the pain was being filtered and being transformed into even more pleasure
