Lilly's deepthroat skills tested by Michael's monster cock

Lilly is not sister to her stepbrother Michael. She is a young girl with natural tits and her stepbrother is always teasing her about her small boobs. He has a big cock and he is always trying to prove it. Today, he decided to test her deepthroat skills. He took off his pants and she started licking his dick. It was the biggest cock she ever saw and it was hard for her to take it in her mouth. But she is a good girl and she managed to take most of it. Then she started sucking it and fingering her pussy at the same time. Michael was masturbating and enjoying her blowjob. He was asking her to take more and more of his cock in her mouth. She was gagging but she was not stopping. In the end, he came all over her face.
