Krissy has proven how tough she is in the past with us, and since I have had my time with her, I decided to let Mason have a go with her. He starts exploring her body and testing her limits, only to find that she has one 'hard no', which is she can't stand drool/spit to touch her body, but, everything else she is OK with. Mason goes straight for her ass and uses everything he can find to put there. He works her ass into overtime, and pushes her body to it's breaking point. Krissy keeps screaming and Mason keeps pushing her until she is overwhelmed by orgasms and finally submits...
