Birthday Buttcrack Disaster

You are at your neighbour's house, helping her prepare for her birthday party. you sit and watch as she pumps up balloons and puts up decorations with her buttcrack slowly slipping more and more out until her whole butt is hanging out of her sagged jeans! she is oblivious to the fact she is giving you quite the eyeful until she stumbles and falls, sitting on her birthday cake! she is upset, for one that you never told her that her whole ass is hanging out of her jeans and also that her birthday is ruined! she runs off to the bedroom in tears! you come in the bedroom and she is there with her big cake covered ass hanging out of her jeans, you admit how sexy you find it and begin to eat the cake off her buttcrack and ass! she encourages you to cum as you devour her cake covered butt! maybe this wasn't the worst birthday ever after all!
