His little sister is a beauty and that’s why he lets her suck him
He always knew that she would be an attractive woman, he just didn’t expect that at such a young age, she would start doing big, slutty woman things. He had to discover this in a surprising way since one day, while sleeping peacefully in his bed separated from the girl’s bedroom, he heard someone enter. He opens his eyes and when he realizes, there is his little sister giving him a blowjob. He wanted to avoid it, only that he is a weak kid and lacks the will to say that it is not correct. Then, since she is a beauty, he lets her suck him and cums in her mouth.
