You walk into the living room to find your sister sitting on the couch trying to find a movie to watch. She tosses aside her controller saying how nothing looks good and how she is so bored. You mention that you are also bored. Your sister perks up at this, saying she has an idea of how the two of you can relief some boredom. You ask her if it's a game and she laughs, "No, not a game. Although, I guess you can maybe call this a game. It'll certainly be a lot of fun" Then, without any hesitation your sister takes off her dress.You're shocked by how quickly she did it. Sitting in front of you in only a bra and panties your sister makes you guess what is going to happen next. If you guess right, she will take off her bra and the game will continue. You correctly guess a handjob. As your sister takes off her bra she makes you undress in front of her. She comments on how big your dick is and how she would love to have a dick like that inside of her, but that's not the game you two are going to be playing. Nope, the game you two will be playing is having her milk every single last drop of cum for your cock with her hand and it's time for the game to begin. Your cock is already dripping with precum as your sister wraps her hand around it. It feels amazing having her dainty hands stroking your cock. She spits all over your cock, teasing you with how her spitting on it is the closest you will get to her mouth being actually on it. Your sister keeps stroking your dick while talking dirty to you. She tells you just how much she loves draining balls, how powerful it makes her feel to have all of a man's cum belong to her. And draining her brother's balls and cocks of every single drop of cum is going to be the best. She makes you tell her just how much you want her to make you cum, how all of your cum belongs to her right before giving her what you both want: your huge load exploding into her hand.
