It's been a while since you and your siblings had some... alone time. This time your sister has instructed you and your twin brother to not masturbate for a couple days to save up lots of cum for her, she doesn't want today to end too soon! She quickly goes to get changed into something more sexy, and wastes no time having you both take your cocks out so she can start giving you both a BJ. She then moves on to riding each of you until you creampie her, still making sure to take care of the other with her mouth of course. While you and your twin are fucking your sister you insist that she leaves her boyfriend so that she can fuck you both full time. She says that she will, but obviously not right now... she's kind of pre occupied, but you guys won't let up about it. She finally agrees to call him mid spit roast and break up with him, even telling him she's fucking two guys right now! She hangs up the phone and continues taking care of the two of you, each of you cumming in her pussy and then moving on to another double BJ for a finale of both of you cumming on her face until she can barely see. I bet you guys are happy you have your sis all to yourselves now!
