Sister deep-throats her brother's manhood so he won't tell her parents she smokes

The cunning brother found a way to get his sister to take in his mouth and give her a blow job after all. He caught her smoking around the corner of the house and now if she wanted him to keep quiet, she had to give a blow job. Sis had no choice but to agree and take it in her mouth. Well after the girl sucked his dick, she took off her panties and let herself be fucked in her shaved pussy with no problem.
