So, this fat girl just moved in to the apartment next door. She was really struggling with all her boxes because your complex doesn't have a lift and she's not used to the exercise. You offer to help her out, mainly just to walk behind her jiggling ass on the stairs, but once it's all done she explains how much weight she's gained recently and since she's clearly been deprived of a good dicking since getting fat, you decide to shoot your shot.
