It's all good until you see her gut. Before you know it shes riding you and she's breathing like a smoker, coughing and can't keep up. I wouldn't hit that.
The shame to be felt afterwards would be astronomical. I'd see that fat cow getting dressed picking up 3x garments wondering how they'll ever fit, then look at her huge fupa and understand. Holding back vomit from the smell of the sweat that slob produced in the half a minute i'd spend inside her, desperately trying to blow my load hoping that it's over soon.
