Don't Tell Parents I'm A Slut

Sybil is a college student who still lives with her strict parents. They are very controlling, especially over her social life. They tend not to like most of her boyfriends, but are particularly unhappy with the young man she is currently seeing. So much so that they have forbidden their daughter from even seeing him. This of course only makes Sybil feel more strongly for him and want to do anything she can to see her boyfriend. On the night of her next scheduled date, Sybil's parents are away, leaving her stepbrother to watch over her. He has been tasked with keeping Sybil at home and away from her boyfriend. She tells brother that she has a very special surprise for her boyfriend and that she will show it to him if he promises to let her go out and not tell their parents. He is curious and agrees to let sister go in exchange for a peek at the surprise. Sybil lifts her long summer dress to reveal that she is not wearing any panties. As he looks up at her bare pussy, Sybil's brother likes what he sees. She notices him staring up at her and feels a tingle in her tight pussy. Since her surprise also included banging her boyfriend all night, Sybil was already horny. Faced with opportunity to further ensure brother's discretion and ride his cock, she had only one thing on her mind, getting his cock into her as quickly as possible. He tries to tell sis that it is wrong, but his cock is so hard that he can't think straight. Sybil has it in her mouth and looks up at him with her pretty eyes. There is no way he can resist and no way he is going to tell his parents anything. She is surprised to see that his cock is even bigger than her boyfriend's and makes her pussy drip long before she rides it. He fills her up and all she can think about is good it feels. Sybil cums so many times she loses track before finally milking a big load from brother's fat cock. He agrees to let her go, but now she knows that she doesn't have to leave the house in order to get the dick she needs.
