The brother did not let his sister go until she gave herself to him.

A beautiful young sister was getting ready for a date late at night, but her brother decided not to let her go. He knew she was going to have sex with her boyfriend, so he decided to take advantage of the situation. He said she could only leave the house after he came in her mouth. The sister realized she had no choice but to comply. The girl knelt down, took her boyfriend's cock in her mouth, and began to playfully give him a blowjob. After sucking him off, the girl got so turned on that she got on all fours and let her older brother fuck her hard. He did just that and, as a gift, came in his sister's mouth.
