MITCHELL ASKS HIS BABY SISTER MANDY TO LET HIM SKETCH HER IN THE NUDE FOR HIS ART PROJECT. SHE AGREES......BUT MITCHELL GETS A BIG BONER!!! ENTERPRISING BABY SISTER TAKES ADVANTAGE OF HER BROTHER'S "SITUATION". SHE CHARGES HIM $300 TO FUCK HER!!! Mitchell needs a favor. He has a big Project due for his Art class at school....it counts for 60% of his Final Grade.....it involves handing in a sketch of a Nude Female Body. Problem is....Mitchell doesn't have a Model. Since the Project is due to be handed in the next day, Mitchell is VERY desperate. So desperate in fact....that he actually asks his Sister, Mandy if she will agree to pose NAKED for him....so he can sketch her. Mandy, of course, is disgusted by the inappropriate request from her Brother....but after some begging from Mitchell....she agrees to take off her clothes and pose Naked. Mitchell begins to draw his Baby Sister Naked.....but within a few minutes, Mandy notices that there is something "wrong". She discovers that her older Brother has a MASSIVE erection in his shorts!!!! Like any Bratty, Baby Sister would do....Mandy immediately confronts her big Brother....and teases him and laughs at him for being aroused by his own Sister. Sensing a perfect opportunity to take advantage of her Sibling....Mandy tells her "Bonered" Brother that she will let him Fuck her.....for a price. The price is....$300!!!! Mitchell is so worked up by the site of his Baby Sister Naked....that he agrees!!! Mandy takes further advantage of her Brother by making him lick her cunt first, before letting him have sex with her. Ha Ha Ha. He pays.......she cums first. Baby Sisters are such Brats!!! Mitchell Pounds his Baby Sister until he unloads all over her tummy. Then he goes back to drawing her.....with semen on her
