(This is a custom clip and I can make one for you too! Just email me at emmasecretmln@yahoo.com or send me a DM) Emma wants her uncle.  He's got nice things, a good job, lots of money and recently, Emma learned he had a great body with the biggest cock she had ever seen.  The only thing he was missing was a hot wife...and his current wife was a nagging, used up gold-digger.  Emma knew he loved big boobs.  She saw his porn collection on his computer, filled with pornstars with fake chests and clips with women pretending to have enormous boobs.  She also suspected he liked young girls...girls Emma's age.  He would often sneak glimpses of her friends, especially those who bloomed early and abundantly. She loves her uncle who often gives her nice things and takes care of her wants.  He deserves someone who can fulfill his fantasies.  Emma buys a potion to make her breasts grow.  Instead of a small dose, she takes the whole thing.  She's overcome with orgasmic joy.  (Either we cut to next part or show growth)Emma goes into her uncles room, her massive boobs bouncing against walls, objects, etc.  She apologizes, explaining she's had a sudden growth spurt.  Little does her uncle know she's already begun seducing him, making sure he can't take her eyes off her face and chest.  She pretends to be worried her boobs are TOO big...and gets him to compliment her enormous rack.  She toys with him further, rubbing her massive boobs against him, getting him to touch her boobs.  She knows he's turned on by the huge bulge in his pants.  She drops to her knees, rubbing her boobs against his cock.  When she pulls it out, she's shocked it so huge.  She knew it was big but this was more than she bargained for...but she presses on, turned on by her fear and anticipation.  She stuffs as much of his cock meat into her mouth as she can, sucking him as best she can.  Between the size of his cock and her boobs, she has trouble but eventually finds her rhythm. Emma says she need him to fill her up.  She'll show him what a young girl can do.  As she stretches herself out pushing her uncle's fat dick inside her dripping pussy, she bounces her boobs, rubbing and squeezing them.  She tells her uncle all the sexual things she does with the boys at school, how much she loves cum and can't wait for him to fill her up.  As she starts fucking herself on his dick, she creams, coating his cock with her girl-juices.  She asks if he's close.  She can tell he is though...and hops off his big dick so he can spray her face and tits with cum.  She jacks his dick, rubs her boobs against him, teases him with her mouth until he explodes all over her.  Just then, off screen, his wife comes in catching her newly glazed niece between her husbands legs. "He's mine now, bitch!  he's going ot fuck my brains out because I got these." She says, shaking her boobs, causing the cum to splatter.
