Mutual Masturbation, Family Lily Lit - Slutty Sister Grounded With Her Horny Brother

Part One Lily and Alex are both grounded for having sex. Their parents expect them to just sit in their rooms alone and bored for the duration of their punishment but that isn't going to work for them. They start talking about how everyone their age is having sex and that it's completely normal and natural. Lily has an idea but she's shy to tell her brother, but he finally gets it out of her. She thinks they should watch each other masturbate and get off together since they can't go out and fuck people. Once thing leads to another and well... Part Two Lily and Alex are still grounded but they have an hour before their parents get home. Ever since he fucked her, she needs more! She straddles him, strips her clothes off and happily takes his cock until she tells him to cum inside of her.
