Christy's mouth gets fucked

Now Christy is sitting on James's lap. The bulge under the guys sweat pants gets bigger and bigger. Christy bites her bottom lip and puts her hand on Rob's pants, slowly pulling them down, giving you looks from corner of her eye. As she takes Rob's pants off, his massive semi-erect cock gets exposed, almost touching Christy's cheeks.

"Oh my, would you look at that John, his half hard dick puts your little hard wee wee to shame little bro" she giggles, emphasizing the word _little, _even though you're actually older. You realize James is holding her hands behind her back as she looks up at Rob with puppy eyes, "May I please, daddy?" she says with a submissive tone before kissing the tip of his cock gently and then starts licking it. With her wrists held behind her back, you'd think she might have a hard time giving a blowjob, but she actually does a good job, licking and kissing Rob's -now fully hard- cock, letting it rest on her face (it covers her whole face when she does this) and licking his balls. From time to time Rob helps her by grabbing a fistful of her hair to keep her head fixed while he slaps her face with his cock. While he does that, Christy smiles widely, looking at you to make sure you can see how she is being used by two strong guys.

Before late, Rob has put the tip of his cock on her lips, slowly shoving it into Christy's tight little mouth. She clearly has opened her mouth as wide as she can to take his cock in. Rob starts moving his cock back and forth in her mouth as he whispers "good girl". Meanwhile James has pulled her shirt up to her neck, grabbing her tits and pinching her nipples which makes her moan with even her mouth full.

James and Rob then change places, with Rob holding you little sisters head while James violently fucks her mouth. Every time he takes her cock out Christy licks her lips and thanks him with a content smile. You can't believe she's such a slut. But this just makes you so much hornier.

She's now kneeling in front of you and between the guys as she puts one hand on each of the guys dicks and starts stroking them, kissing their balls and licking them in turn, her face and her tits are not wet from her spit. "You see what a real man looks like John?" she laughs with a very mean tone. "Do you think that little thing of yours you call dick is going to make any girl happy?" she continues laughing. You really don't want to enjoy this so visibly, buy your cock starts twitching as she humiliates you. "OMG, look how much he loves being roasted by his little sister" laughs Christy, "LOSER".
